More ways to celebrate success and innovation

38

At the time of writing, we know that something took place in at least 153 countries to mark the first World Refrigeration Day. As Steve Gill says on page 18, it was remarkable to see the scale and reach of the event, and to witness the global industry come together for a common cause.

It is a fantastic achievement and, with what has been learnt this year, the vision for 2020 will be bigger and better.

One of the key challenges now is to take the message of what this industry is all about to a more mainstream audience.

In the meantime, we should take every opportunity to celebrate excellence and innovation and one way to do that is by entering your project or product for the National ACR & Heat Pump Awards, which will be staged once again at Manchester’s Midland Hotel on January 23, 2020.

There are categories to cover every aspect of the air conditioning, refrigeration and heat pump sector, so this is the perfect opportunity to tell your story.

For full details of the categories, how to enter or to book places, visit: www.acrheatpumpawards.co.uk In this issue we feature a new column from an industry insider and shine the spotlight on two historic names from the Midlands, Carters and Conex Bänninger.

We look at the resurgence of chillers, some of the options available for leak detection, plus the usual mix of news, views and updates.

R32 Big PACi launched

Panasonic has introduced the Big PACi series of air conditioning equipment in 20kW and 25kW capacities, using R32 refrigerant.

The new models include a water heat exchanger option, which the manufacturer says provides an ideal alternative to traditional boiler systems for small retail spaces and office projects that are environmentally conscious.

Designed for easy installation, the new models have a more compact indoor chassis with a reduced depth by 230mm versus the conventional Big PACi R410 range. The compact design still maintains the same level of efficiency overall, with an SEER rating of up to 5.25 and SCOP rating of 3.61.

In addition, R32 PACi includes a split-able duct indoor unit which can be divided into the heat exchanger and fan parts, allowing for easier installation within narrow spaces such as small retail shops. The indoor unit is also up to 16kg lighter in weight than conventional Big PACi R410 model.

LG ADDS R32 SPLIT TO THERMA V LINE-UP LG Electronics has added an R32 split to its Therma V air to water heat pump systems.

Designed for the new and housing renovation markets, the Therma V R32 Split is described

by LG as a versatile solution that can deliver effective space heating and hot water supply, with an advanced compressor helping it to achieve the most powerful heating performance yet from a Therma V product.

The R1 is said to be the world's first ‘shaft-through’ hybrid scrollshaped compressor and LG says its technology eliminates the tilting motion of the scroll, minimizing energy waste and increasing overall reliability. It adds that the compressor makes the Therma V R32 Split quieter and more durable, and also enhances heating performance, ensuring reliable operation at a low ambient temperature of -25°C. The Therma V Split boasts a Seasonal Coefficient of Performance (SCOP) of 4.65 in heating operation and an Energy-related Product (ErP) rating of A+++ dependent on a return water temperature of 35°C. It has 100% capacity at temperatures down to -7°C. The SmartThinQ smartphone app enables remote control and monitoring, allowing users to select or change mode, set the temperature, monitor energy consumption, or even ‘pre-heat’ a room.

AERONA³ EARNS LOW NOISE ACCOLADE Grant UK's Aerona³ R32 13kW and 17kW heat pumps have achieved the Quiet Mark, an accolade which recognises some of the quietest, high performing products in the market.

Quiet Mark is the international award programme validating and awarding low-noise, high performance technologies which help to deliver solutions which can overcome noise pollution throughout the world. Associated with the UK Noise Abatement Society charitable foundation, Quiet Mark encourages companies across the globe to prioritise noise reduction within the design of their products.

Grant UK managing director Paul Wakefield said: “The awarding of the Quiet Mark to the 13kW and 17kW models is something we are very proud of as it reflects how quiet these heat pumps are, something which is important to householders. Quiet in operation and compact in size, these Aerona³ R32 heat pumps have minimal impact on their surrounds being our greenest, most efficient and quietest heat pumps yet.”

Grant recently added four new models to its Aerona³ R32 range, with outputs ranging from 6kW up to 17kW. °S tep-by-step guide to underfloor heating, page 62.

Confirming a low GWP future Carrier has confirmed it will choose low GWP HFO refrigerants for most of its commercial heating, ventilating and air conditioning products in Europe, where it says it has achieved a reduction of the refrigerant charge in its products of up to 50% over the last five years.

Carrier has been working to select the best candidate to replace R134a in screw and centrifugal chillers and R410A in scroll chillers, heat pumps and rooftop units.

For screw chillers and heat pumps, Carrier selected R1234ze to replace R134a, with R1233zd(E) chosen as the preferred longterm refrigerant for centrifugal chillers.

For scroll commercial chillers and heat pump ranges, Carrier says that currently available compressor technology is not compatible with low GWP HFO refrigerants. Some solutions operate with mid-GWP HFC refrigerants and Carrier says it is developing a full range of cooling and heating products that will comply with and exceed Eco-design 2021 efficiency requirements and operate with mid-GWP HFC refrigerants.

MODULAR CHILLERS IN ARENA SPOTLIGHT Audiences at the M&S Bank Arena in Liverpool are being kept comfortable by 46 e-Series modular chillers from Mitsubishi Electric.

In December 2017 the arena’s carpark, where the previous chillers were housed, was hit by a fire and the new solution needed to be installed in the limited space on and around the arena itself. The final design sees 11 90kW units installed on each of the four roof plant decks and two chillers installed on a gantry within the loading bay.

The design for The ACC Liverpool Group’s systems was undertaken by Redworth Associates, taking advantage of the modular nature of the e-Series which allows for up to six units to be connected in a design which best fits any given space. With a capacity ranging from 90kW to 1,080kW, they can provide space savings of up to 35% compared to traditional chillers.

During the installation, the Arena benefitted from e-Series units being available for next day delivery, rather than with the usual 8-10 week lead time which is commonly required for traditional chillers, enabling the venue to reduce the costs associated with the hire of temporary cooling. The units were installed during the winter months when cooling requirements were less in demand.

With two inverter-driven compressors per module, the chillers have a wide operating range of between 8%-100% capacity, offering exceptional part-load efficiencies. As this range is where most chiller systems will operate for most of the time, this capability provides significant real-life efficiency savings. °E mbracing the benefits of modular chillers, page 22.

TOSHIBA COMPLETES R32 SPLITS RANGE Toshiba has completed its line-up of Super Digital inverter (SDI) equipment. The latest additions to the light commercial R32 range include the new Big Super Digital inverter (SDI) outdoor unit, available in 8hp and 10hp versions, and a complete range of R32 indoor units, including ceiling cassettes, high-walls, consoles and high static pressure duct-mounted units.

The systems have energy ratings of A+++/A++ and deliver cooling with a Seasonal Energy Efficiency Rating (SEER) of up to 7.01, and heating with a Seasonal Coefficient of Performance (SCOP) of up to 4.36, depending on the model and outdoor-indoor unit combination.

As a result of design improvements and system optimisation, the refrigerant charge has been significantly reduced, from 5.9kg in the previous model to 5kg in the latest version.

Neil Hitching, sales director for Toshiba, said: “The new SDI systems have been totally redesigned to maximise safety and performance with A2L-class refrigerants, such as R32. This is great news for users of Toshiba equipment, who now have access to the widest range of R32 splits from a single supplier, backed by our industry leading warranty and customer service.”

Mark Woods takes the chair at FETA

Mark Woods is the new chairman of the Federation of Environmental Trade Associations (FETA). He replaces Nick Howlett, who remains as HEVAC president and will be closely involved in the review and update of the Building Regulations.

Mark Woods is the owner/ operator of contractor and industry consultancy RefMech and was previously managing director of Space Engineering Services. Having started his career as an apprentice at Carter Refrigeration, he has held several technical and leadership roles in his 33 years in the industry, which include being a member of the EURIS panel representing industry during the Brexit process, and also being a panel member for the new T Level qualification in Refrigeration, which is due for launch in 2021.

The BRA has also elected Mark Hughes as vice president. Mark works for Chemours, where his role is business development manager for Opteon refrigerants. He is also vice chairman of the BRA Equipment and Components section and represents the BRA on a BSI standards committee.

Hybrid solution from Coolair

Coolair Equipment has secured a £150,000 contract to install a heating and cooling system for a major office redevelopment in central London.

The commission, from mechanical services specialist VMEC on behalf of main contractor Phoenix Construction Services, is part of a multi-million-pound upgrade for Elizabeth House, close to Gray’s Inn Fields in Holborn.

Coolair will equip the building with a new Mitsubishi Electric hybrid VRF ducted air conditioning system that combines refrigerant and water to ensure leak-tight simultaneous heating and cooling. With piping carrying water instead of gas, the system’s modular two-pipe design removes the use of refrigerant and the need for leak detection equipment in occupied areas.

As an accredited Diamond Quality Partner of Mitsubishi Electric, Coolair Equipment’s new National Aftersales Division has also signed an annual maintenance agreement that includes a sevenyear warranty on the system.

LODAM RENAMED BITZER ELECTRONICS BITZER subsidiary Lodam Electronics has been renamed BITZER Electronics. The Danish controls company was acquired in 2007 and motor protection devices, IQ modules and frequency inverters from Lodam are now a key part of all BITZER compressors.

AIREDALE INTRODUCES R32 AZURE RANGE Airedale International has launched a new range of R32-optimised air conditioning products. The Azure line-up, which has been under development for almost two years at the manufacturer’s research & development facility in Leeds, has been optimised to operate at the same high level of output and efficiency as existing Airedale products whilst utilising the lower GWP refrigerant R32.

The first products to be launched are the Ultima R32 compact 30-150kW chiller and the DeltaChill 110-1100kW R32 chiller.

Additional items, including precision cooling units, are expected to follow in the coming months.

The Ultima R32 is a high efficiency, compact, aircooled single/dual circuit chiller. Optimised for R32 and now operational with an increased supply water temperature of up to 18°C, Airedale says the Ultima R32 has been engineered to increase efficiency and deliver improved performance.

New BESA president elected

John Norfolk has been elected as president of the Building Engineering Services Association (BESA) for 2019/20. He takes over from Tim Hopkinson of E Poppleton & Son, who served for two years.

Mr Norfolk is senior project manager at Imtech Engineering Services. He was chair of BESA Yorkshire region from 2010 to 2012 and is a long serving member of the association’s membership and legal & commercial committees.

He described BESA members as the association’s greatest asset and pledged to build on the technical legacy of the 115-year-old body to help tackle the modern challenges created by climate change and the need for better buildings to help address social problems.

He paid tribute to Mr Hopkinson and thanked him for taking on the “extra burden and responsibility” of a second year in office in order to “steer the Association through some choppy waters”.

“It is no secret that we went through a tricky period, but Tim managed to steady the ship in his first year before putting in place some crucial building blocks,” added Mr Norfolk.

FIRST MEETING OF YOUNG ENGINEERS

TESCO TARGETS AEROFOIL TRANSFORMATION Tesco is working with UK technology company Aerofoil Energy to transform the performance of refrigeration cabinets in its stores using of Formula One-inspired aerodynamics.

The roll-out of Aerofoils in Tesco supermarkets throughout the UK and Ireland is said to represent the largest adoption of shelf-edge technology to date. Tesco will also adopt Aerofoil Energy’s Vortex technology for its new fridges, with the aim of delivering energy and carbon emissions savings to rival that of cabinets with glass doors.

Inspired engineering The Aerofoil uses aerodynamics developed with Williams Advanced Engineering to guide cold air more efficiently down the front of the fridge and resuce cold air being lost from the cabinet.

Vortex is the future-fridge technology project of Aerofoil Energy. Using Computational Fluid Dynamics modelling with technical partner Williams Advanced Engineering, Aerofoil Energy’s Vortex technology is applicable

to both existing and new-build refrigerated cabinets.

Paul McAndrew of Aerofoil Energy said: “Rolling out Aerofoils across an estate the size of Tesco’s will have a tangible impact on energy consumption at a national level and confirms Aerofoil Energy as the number one choice for shelf-edge technology. But that’s only half the story – adopting our Vortex technology for Tesco’s new-build cabinets will set a new standard for energy and temperature performance in supermarket refrigeration.”

Craig Wilson, managing director of Williams Advanced Engineering, said: “Our mission is to deliver inspired engineering for a sustainable future and it is great news to see the adoption of this technology by such a respected global retailer.”

Sainsbury's, Asda, Boots, M&S, Scotmid Co-op and WH Smith are among the retailers who also use the Aerofoil technology. Aerfofoil Energy says it has supplied more than 960,000 units for 21 retailers worldwide.

The IOR Young Engineers’ Network met at Clade Engineering for an event which combined a site tour and opportunities for young RACHP engineers to make new contacts within the industry. The group was set up earlier this year and aims to offer a platform for engineers under the age of 35 to network and have access to sites, facilities and information sources otherwise unavailable to them.

Yousaf Mohammed, from Clade Engineering, said: “As a young engineer I was pleased to be asked to organise the first IOR Young Engineers visit to our manufacturing plant here at Clade. It was a fantastic experience and I made loads of new contacts. Being able to connect personally and build professional relationships with other engineers face to face was a really positive experience.

Also, understanding what others do in the industry, I believe, will help us and the refrigeration industry in the future.”

The Young Engineers’ Network is planning future events which will be announced in due course on the IOR’s web site and social media. To join the mailing list contact ior@ior.org.uk

VRF FOR NOVOTEL YORK Guests at Novotel’s extended York centre hotel will benefit from Toshiba heat recovery VRF air conditioning.

The 2,500 square foot extension includes 16 new deluxe rooms and six junior suites, air conditioned by four Toshiba Super Heat Recovery Multi (SHRM-e) VRF systems and additional Super Digital inverter systems, with ducted indoor units.

The project needed to meet the client’s performance specification under the Building Research Establishment Environmental Assessment Method (BREEAM) and BS EN378 and also required a particular focus on low noise operation.

The system was installed by JH Shouksmith & Sons, and equipment was supplied by Toshiba distributor Cool Solutions Distribution.

13 INSTALLERS VISIT PANASONIC FACTORY

Installers from the UK and Ireland visited the new Panasonic heat pump factory in the Czech Republic.

The factory began production of Panasonic’s air to water heat pumps last year to help meet the growing demand and ensure shorter lead times within Europe. Starting with one production line, manufacturing at the factory will progressively increase to reach 40,000 Aquarea units yearly, according to Panasonic’s mid-term plan.

Panasonic had previously exported air to water heat pumps to Europe from its Malaysian factory and says the new facility enables it to meet growing demand for energy-efficient heating and cooling in properties across the region.

For Panasonic customers in Europe, Aquarea lead times will be reduced thanks to short-haul transportation links, which also contributes to a reduction in the environmental impact of long-haul product shipping from Malaysia.

It all comes down to choice Andrew Slater looks forward to a return of increased options for the air conditioning market. contrast, has taken the initiative of offering an array of options. The priority of capital cost, operating cost or environmental benefit has been given to the customer as a choice when selecting a chiller.

The selections of available refrigerants for each application, such as R452B, R454B, R513A and R1234ze, plus multi refrigerant compressors, have made this possible.

It is important that we understand that most of these refrigerant options are only intermediary and emphasis should be on transitioning towards ultra low GWP options to meet F-Gas phase down targets, but even so there is still a choice.

Short-term solutions

The chiller market has taken the initiative of offering an array of options

It is only through choice that a competitive market place is possible. Driven through innovation and steered generally by legislation, we have seen the HVAC industry consistently progress to be more energy efficient and increasingly more environmentally friendly.

The refrigeration and air conditioning sectors have always been quite different, especially since the rise of the VRF system.

Inverter technology, flexible design options and smaller plant space requirements saw the application of small chillers rapidly replaced by the all-inclusive VRF. Now it seems that through a lack of choice the pendulum is perhaps swinging back, through changes in building certification, legislation with regards to leak detection, an increase in modular chiller capabilities and the F-Gas phase down.

Whilst including flexible design capabilities and packed with cutting edge

technologies, the air conditioning sector appears to be somewhat stuck for the moment because of a lack of viable options for refrigerants. The chiller market, in

Andrew Slater is managing director of HVAC Communications.

Through extensive marketing, the air conditioning sector seems to have been steered towards R32 as a lower GWP alternative to R410A. As a 50% component of R410A, the continued emphasis on launching R32 product ranges will eventually lead to a loss of available options for servicing the extensive number of VRF systems currently operational without exceeding refrigerant quotas.

In addition, R32 air to water heat pumps have also been introduced into a rapidly growing domestic market. Should we have used this potentially mass market in its infancy to implement the relatively large design changes in order to accommodate ultra-low GWP refrigerants? Or are we simply looking at short-term solutions with short-term gain?

It is still important that the industry focuses on recycling refrigerant to work around quotas and provide service options for existing equipment, even though the research carried out by Honeywell to find alternative refrigerants for R410A has been refreshing. First R466A, as a short-term solution to rival R32, and now development work on the longer term HDR-147 is taking place.

There are still some concessions that need to be made in terms of building regulations to return VRF to a more solid proposal, but hopefully now the air conditioning sector is moving towards having design choice once again.

Top 50 honour for engineers Industry women named on prestigious list.

Two female engineers from the refrigeration and air conditioning industry have been included in the Top 50 Women in Engineering (WE50) list for 2019.

The WE50, now in its fourth year, is organised by the Women’s Engineering Society and coincides with International Women in Engineering Day each June.

Institute of Refrigeration board member Jacinta Caden and Lisa-Jayne Cook, a fellow member of the Women in RACHP steering group, received their awards at the Royal Academy of Engineering.

Jacinta, who was named Woman of the Year at the National ACR & Heat Pump Awards in January, has been in the industry since 2003 and now works in a business development role for Critical Project Services, a management consultancy with particular emphasis on data centre projects.

She said: “The WE50 theme this year was Current or Former Apprentices and was open to all engineering-related disciplines, so to have the RACHP industry highlighted in this capacity is fantastic. Apprenticeships are not being chosen frequently enough as a route to a successful career which is disappointing and also the reason why WES decided to focus on this for its centenary year. As we all know, theory is essential but the exposure to a working environment that an apprenticeship provides is an invaluable experience to have as a foundation and move forward with.

Raising STEM profile “As an industry we are working to improve the quality of people and skills coming through. It is our responsibility as mentors, employers, parents and professionals to encourage the young people of today to consider apprenticeships. It is an ongoing exercise and we can raise awareness on the great industry we have while also taking pride in offering excellent standards of apprenticeships.

“If we are to continue providing the essential services of RACHP we need to do more, and offering quality apprenticeships

is one way to do this. I was delighted to be able to raise awareness in this way and I hope we continue to get involved in any capacity because every step forward is a step in the right direction.’’

Lisa-Jayne spent 16 years at Kelvion and also worked at Aqua Group before recently joining J&E Hall as a sales and applications engineer.

She said: “I am thrilled that both Jacinta and I have been recognised with our inclusion in the WE50 list this year. I am extremely proud of our achievement, especially considering the calibre of the other nominees. This award has provided a significant boost for our working group and has already helped us to elevate the profile of Women in RACHP. While there aren’t many of us, we are here and we are determined to level the playing field.

“WES campaigns, such as WE50, aim to raise the profile of women in STEM careers and highlight the skills shortage we are

suffering in all engineering-based fields. I hope that the valuable work both WES and the Women in RACHP group are doing will break down the prejudices we still face in such male-dominated roles, and that we will inspire the next generation to take up careers in STEM which they can enjoy without the challenges and biases previous generations have faced.’’

Dawn Childs, WES president, said: “Apprenticeships remain one of the key routes for technical education and subsequently, to qualifying as an engineer.

Consequently, we have looked at current and former apprentices in the WE50 list this year. The breadth and depth of roles and industries covered by the entries was simply breathtaking and the achievements of the individual entrants were stunning – we have definitely found another truly inspirational list of female engineers!” www.inwed.org.uk/we50-2019

The coolest (and longest) day of the year

something had changed; it was as if the floodgates had opened to let the industry tell its own message with a louder voice than ever before.

We asked founder Steve Gill for his personal recollections of the first World Refrigeration Day. So, World Refrigeration Day actually happened. How did you feel immediately afterwards?

Immediately afterwards I felt exhausted!

The Coolest Day of the Year was also the longest day of the year for me. There had been a lot going on in the run-up to June 26 but everything really took off on June 25 when I woke early (around 5am) to find over 700 new emails. The emails kept arriving at the rate of around 100 per hour; as soon as I had answered one, three or four more had arrived.

I was in Kansas City at the time and hardly left my hotel room as I worked to reply to as many as I could. By the evening I was drained but I saw a message from New Zealand saying that WRD was about to start there. I was tired, but also excited and thrilled that WRD had arrived.

After my first LinkedIn video post, I watched a live webinar from New Zealand.

Matthew Darby from EcoChill interviewed some young people in a panel-style session.

Even though it was on the other side of the world, it was easy to relate to these young people. WRD was connecting people.

After that, I watched online via social

media as WRD rippled across the globe.

I should have gone to bed but I became drawn to the fascinating event that was unfolding. By 2.30 am Kansas City time, I was due on a webinar organised by Danfoss with a great line-up of speakers from Asia and particularly India. By the time that finished I had already been awake for 24 hours, but I had to prepare for another webinar that I would be hosting for UNEP and ASHRAE. Immediately after the webinar ended, I flew down to Miami for the RefriAmĂŠricas Exhibition and Conference. As I arrived at the conference I was whisked straight onto the stage and handed a microphone and gave a short speech about WRD which was translated into Spanish as this was the main language of the attendees.

So, how did I feel immediately afterwards? Exhausted yes, but absolutely thrilled. There was a real sense that something extra special had just happened. As an industry we had become a community like never before. The scale of it and reach of it had surprised many. I also had a sense of relief, because this could so easily have failed, and a sense that

Do you know how many countries were actually involved?

We are still collecting data and continue to be surprised. At the moment we believe it was marked in some way by physical events in at least 153 countries. This is truly astonishing but it is not just the number of countries that is amazing, it is that in many countries there were multiple events. In India, for example, the national association ISHRAE organised 18 events but indications are that there were significantly more things taking place. I am working with UNEP and others to try and gather the data but, in truth, we may never know exactly how many events took place and where they were.

What made you most proud about the way the industry responded?

I think our industry united and revealed itself as a global community. After the day, I started to refer to WRD as a community project because that is what I always hoped it would be. What made me most proud is that the industry responded with a community spirit.

I was proud of the way our trade associations and professional societies responded by supporting the concept of WRD. Anyone with experience of being involved in one of these organisations will

INDUSTRY FO CU S know that they are often managed by a voluntary board that only meets a few times a year so reaching a decision can be a slow process. Thankfully, over time, they have responded and supported WRD. Some as late as the day before suddenly wished to support it, while others such as the IIR, IOR, ASHRAE, AIRAH, ISHRAE, AREA etc have been involved and supportive for some time.

Then, of course, there are the businesses and individuals working in the sector. A great many of these responded by planning events and actively being involved. We also put a call out for sponsors as the costs involved began to mount. A small number of businesses responded without hesitation and became sponsors. I will be eternally grateful for this as without them we couldn’t have done a fraction of what we did. What many people perhaps do not appreciate is that there is no funding, and the whole thing has been put together by myself in my spare time, with help from a few others from time to time. So the sponsorship was really very important.

I was also proud of our trade press, both here in the UK and abroad, who all supported WRD by carrying news items.

Is it too early to ask about plans and ambitions for 2020?

It is too early for specifics but I can tell you that we will be aiming to extend the approaches that we piloted this year; reaching out to young people and their advisers/influencers through either open days or directly going into educational establishments. We will be launching this very shortly after consulting with our partners and sponsors so that we may better resource for WRD20. We want to make a real difference and that requires year-round activities.

The Institute of Refrigeration chose the day to launch two new sections of its website for young people. The site – www.fantasticfridges.com – aims to explain the practical science behind the technology and help young people to understand the contribution that refrigeration, air conditioning and heat pumps makes to modern life – as well as the career opportunities available.

The IOR is also launching a Cool for School competition which aims to challenge KS3 students to explore the science, technology, engineering and mathematical principles that underlie refrigeration processes, and come up with a video of simple experiment or presentation to demonstrate one of these. Prizes include £2,000 worth of science kit for the winning team’s school. A number of businesses are supporting the initiative with prizes, including FJB Systems, 3CL, Airmaster, Ellis Training Works, Haier Group, Integral, J&E Hall, the JD Cooling Group, Sure Solutions, Star Refrigeration, Artic Circle, CRT, GEA, and BITZER.

Climalife UK got into the spirit by hiring an ice cream machine for the day at head office and handing out free treats to staff, friends, local businesses and customers.

Marketing co-ordinator Mel Summers said: “We started the day with the launch of our group video that looks at how cooling touches our everyday lives and then opened our doors to welcome friends, colleagues, local businesses and customers. Many of the staff suggested we have an ice cream machine on site permanently!”

At Space Engineering Services, the directors and senior managers took time out to mark the day and reflect on the incredible advancements in refrigeration. The company said it saw the day as an opportunity to not only draw the world's attention to just how vital refrigeration is, but to also celebrate the people that make it all happen.

Cutting down the risks Falling levels of competence and the problems of using generic risk assessments were highlighted at the IOR Annual Conference.

David Paget, John Ellis and Maurice Young during the morning session

The Institute of Refrigeration’s Annual Conference in Birmingham explored a series of key areas around risk assessments and refrigerant safety.

Keynote speaker Maurice Young, from Maurice Young Consulting, outlined the need for risk assessments and the crucial role they play in ensuring a safe workplace.

Meeting the legal requirements is the minimum standard for health and safety but employers must keep risks as low as reasonably practicable (ALARP).

He stressed the importance of risk assessments relating to specific sites and circumstances and went on to add that any associated costs were outweighed by the potential cost of non-compliance.

He said: “It is three years since the implementation of the UK Sentencing Council’s Health and Safety Offences, Corporate Manslaughter and Food Safety and Hygiene Offences: Definitive Guideline.

“In the first year we saw, as predicted, that the courts weren’t shy about imposing high fines for organisations and custodial sentences for individuals for breaching health and safety legislation. A significant number of cases attracted fines in excess of £1million, many in non-fatal cases, and this is a trend that is likely to continue.’’

His stark closing message was: Work safely today. Remember, someone expects you home tonight.

John Ellis, of Ellis Training Works, underlined the need for site-specific

August | September 2019

IOR conference.indd 20

risk assessments and said a declining level of competence in the industry was having a significant impact. He said: “It is common knowledge that the proportion of technicians/service engineers who have basic Level 2 qualifications which include a Health and Safety unit has fallen off significantly over the last 10 years, since F-Gas certification became the legal minimum requirement to work in the industry. This in turn provides further challenges to managers and supervisors seeking to fulfil their obligation vis a vis risk assessment, method statement and safe working procedures. It is obvious that someone with 4/5 days of training is less able than someone with 60 days of formal training!

“The outcome is often that ‘generic’ forms are developed over time and issued as ‘tick box’ assessments to be completed on site by the technician to show that a ‘risk assessment’ has been carried out. There is a common view that once boxes are ticked, the risk assessment has somehow become ‘dynamic’ with little understanding of the actual risks and liabilities to the parties who are involved.’’

David Paget, chair of the IOR Technical Committee, launched a new Guidance Note on Point of Work Risk Assessments (POWRA), which are designed to support existing processes by providing an opportunity for individuals or a team to consider their ability to undertake the task,

Dermot Cotter introduces the conference

identify the hazards and risks local to the task, just before they start the work, no matter how familiar they are with the site.

The POWRA follows four steps: Stop, Think, Act, Review; and is designed to raise awareness of health and safety considerations for both the workers undertaking the task and those in the area. It should also identify training and equipment needs, provide a dynamic and ongoing assessment in a changing workplace, be site specific and allow for a review and record lessons learnt.

The guidance note is available to download from the publications section of the IOR website.

Dermot Cotter, from Star Technical Solutions, looked at safety and risk assessments for flammable refrigerant and began by highlighting a point raised earlier

by Maurice Young, that since 2015 ALL refrigerants are covered by the Dangerous Substance and Explosive Atmosphere Regulations (DSEAR). He added that DSEAR should always form part of a wider risk assessment.

He pointed out that BS EN378 is not just about limiting the quantities of refrigerant to be used and urged delegates consider all parts of the guidance.

Andy Pearson spoke about the challenges of working on installed systems

Andy Pearson, of Star Refrigeration, looked at the particular risks associated with working on installed systems, where taking over a maintenance contract can lead to inherited problems. He said it was important to try to gauge to the previous contractor’s attitude to health & safety issues and always expect the unexpected.

The key questions, he said, whether looking at the original design, as installed or in operation, are: Is it safe? Was it ever safe? He also advised contractors:

“Assume it’s broken until you have proved otherwise!’’ He added: “Using the switch of maintenance provider as a trigger to instigate a thorough review of plant condition and performance might seem like the addition of unnecessary hassle, but it is likely to pay off through reduced operating cost, reduced lost time accidents and reduced service charges.’’

Graeme Fox, head of REFCOM and senior mechanical engineer at BESA, said that risk assessments in the building services sector were often generic. He also pointed out that anyone carrying out a risk assessment needed to be competent themselves.

Referring to earlier comments about levels of competence, he said: “F-Gas does not make people competent; that only comes with experience. It is a sad state of affairs for the industry to be in and something we need to address.’’

Putting the focus on air conditioning

systems and building services, Graeme also explained why all four parts of EN378 were applicable at different times and said he fully understood what a daunting proposition the legislative landscape could be as a former air conditioning contractor imself.

He said AREA, the European association of RACHP contractors, has produced guidance in the form of an introduction to EN378, plus an F-Gas EN378 compliance checker app.

Brian Minchin and Marcella Davies from Lloyd’s Register examined the particular risks associated with working at height. According to Health and Safety Executive figures, falls from height account for 26% of all fatal injuries (an average of 37 fatalities per year), with half of those deaths in the last five years occurring in the construction sector. www.ior.org

The innovation behind Fujitsu's new chiller range In 2017 Fujitsu General Ltd signed a strategic collaboration agreement with GI Holding Group (GIH), an HVAC product manufacturer, for the joint development of dedicated product ranges of both residential and commercial air conditioners.

A result of this agreement sees Fujitsu General Air Conditioning UK also supply a full range of Clint liquid chillers and Montair close control systems, both historical brands from the portfolio of GIH. Linked to the Carbon Road Map set by the European Union, to reduce Greenhouse Gases (GHG) by 80% compared to 1990 levels, are the F-Gas and EcoDesign directives. F-Gas focuses on the direct impact of the release of refrigerant into the atmosphere contributing to the greenhouse effect, whilst EcoDesign focuses on the indirect impact of energy consumption.

Ian Carroll, Chief Operating Officer, Fujitsu General Air Conditioning UK said: “The innovation and flexibility that GIH demonstrate makes them an ideal

ADVERTO RIAL partner, especially when applying our newly available chiller products into the UK market. They have focused on alternative refrigerant options to assist F-Gas phase down, and in doing so negates future complications with current HFC refrigerants such as availability and increases in price. With regards to performance and application, the different product lines overlap between both capacity and compressor type. The specifier can now choose quite easily a product that benefits in capital cost, efficiency and environmental impact, through low GWP refrigerants. Our dedicated in-house Fujitsu team has been placed to assist with design, selection and aftersales support of these products” An extensive range of liquid chillers, heat pumps and multifunctional ‘4 pipe units’, with scroll compressors, are available.

With cooling capacities ranging between 50 kW and 1.2 MW, operating on either R410A, R452B or R454B. Scroll and Turbocor compressor options are available from 200 kW to 3.8MW, using R513A or the ultra-low GWP R1234ze as alternatives to R134A.

23

Refrigerant variety Martyn Ives, Technical Manager for Fujitsu General Air Conditioning UK, goes on to explain: “R32 has always been a viable option for both direct expansion and hydronic applications when looking for lower GWP alternatives to R410A. GIH decided to offer refrigerant options that had a closer operating envelope to R410A and less GWP. Because of the nature of the fluids, the same refrigerant oil can be used and therefore a multi refrigerant compressor can be applied, rather than stocking a dedicated compressor to each type of refrigerant. This level of research has propelled GIH to be Danfoss’s largest customer and work closely on collective development projects. The efficiency when using R452B is 1% better than R410A, with only a 2% decrease in cooling capacity. R454B is a further alternative for those customers with a real environmental focus. Its cooling capacity is 4% less than R410A, but maintains the same efficiency, its GWP is just 467 kg CO2EQ, compared to 1924 of R410A and 677 of R32.”

“The Screw and Turbocor based products offer similar alternative options. R513A instead of R134A, and the HFO R1234ze, with an ultra-low GWP of less than 1.

Being non-toxic and classified as A2L, this refrigerant is seen also as an alternative for ammonia and propane. The cooling capacity is 18% less when compared to

R513a, but with a 3% better efficiency rating. It offers zero environmental impact and has seen projects won based on its low Total Equivalent Warming Impact (TEWI).”

Product innovation With both direct and indirect environmental impacts in mind, the collaboration in testing and development

by GIH of a new style ‘hybrid’ heat exchanger emphasises the innovative qualities embedded in its design teams.

A balanced cascade of refrigerant across the evaporator tubing, results in up to a 40% reduction in refrigerant volume when comparing to a flooded evaporator.

This new design improves heat transfer performance and maintains heat transfer coefficient at partial loads, typical of an organisation striving forward to assist the reduction of greenhouse gases.

Whilst maintaining access to Clint and

Montair’s full product line-up and associated products such as dry coolers and air handling units, later in 2019 will see the launch of Fujitsu General Ltd and GI Holdings' first codeveloped compact Mini Chiller heat pumps.

They will be available in the UK, adding to Fujitsu's extensive HVAC line-up and demonstrating the partnership’s substantial design and manufacturing capabilities.

Embracing the benefits of a modular future

Modular chillers offer a new way of solving space, performance and noise issues for our changing buildings, says Arnav Maini of Mitsubishi Electric.

In the past, there were very clear lines between what was considered a commercial zone, full of commercial buildings, offices and factories, and what was residential.

Over the years, the boundaries have blurred as an ongoing urban migration has led to people living and working in buildings, particularly in towns and cities, side by side.

This change has required us to think differently about the approach we take when it comes to our heating, ventilation and cooling systems.

Traditional chillers were often the popular choice historically, and still have a place in the market in the right situation.

However, with a rising urban population, and shifting working and living practices emerging, it’s time to revisit some of the unique benefits that a modular approach can bring to building owners and managers.

Modular chillers have been designed to use variable speed fans and compressors, and the Mitsubishi e-Series chiller operates with a two-stage cooling circuit.

By modulating temperatures individually, the e-Series increases overall system efficiencies by 4% compared to chillers with a single refrigeration cycle.

In an installation of six modular chillers of 180kW each, if one compressor breaks down, only 8% of capacity will be lost

August | September 2019

Modular chillers.indd 24

Designed for the urban environment

The 90kW eSeries modular chiller from Mitsubishi Electric runs at 77db

As a result of this level of control, modular chillers are able to closely meet the efficiency requirements of projects where the need for cooling is particularly changeable, resulting in significant energy savings over time.

Modular chillers also offer significant part-load efficiencies, and higher capacity models have been designed with more advanced controls, making them easier to operate in a more flexible manner.

In the increasingly dense urban parts of the UK, in areas with space restraints, modular chillers can readily be fitted onto rooftops to offer flexibility in both installation and positioning. Overall, modular systems can save up to 35% of space compared to traditional chillers.

The 90kW e-Series modular chillers also use a U-shaped heat exchanger, the design of which allows the units to be narrower than conventional chillers, making the units perfect for sites with restricted space or access – often found in a busy city!

As residential areas continue to be built alongside hotels, office and restaurants, sound levels become a greater concern for the managers of multi-purpose buildings.

Modular chillers, by their nature, are particularly quiet. A conventional large capacity chiller operates at over 100db; while the 90kW eSeries modular chiller, for example, runs at 77db. In practice, 20 eSeries modular chillers on a rooftop would still produce less noise than a single conventional chiller.

Modular redundancy A chiller system with multiple modules can also offer high levels of reliability, as there will be a limited impact in the event of module failure. If one module fails, the others will continue to function, and only a small proportion of capacity will be lost. For example, in an installation of six modular chillers of 180kW each, if one compressor breaks down, only 8% of capacity will be lost. On the other hand, if the compressor in a large traditional chiller fails for any reason, the system will lose 50% of its capacity.

Case Study: ASDA House

Lifetime value The durability and energy efficiency of modular chillers can also offer significant cost savings. Upgrading an old, outof-date system with new equipment inevitably brings better and more reliable performance for end users, which can result both in more efficient operation and less need for maintenance calls outs.

They are also an ‘off-the-shelf’ product, delivered to site pre-packaged, pre-piped and pre-wired, only needing to be connected to a power supply, in comparison to traditional chillers, which usually take six to eight weeks to be delivered and deployed. In time-sensitive projects, this can be particularly beneficial, substantially reducing time-on-site for installers.

The Mitsubishi e-Series modular chillers are also designed with an in-built internal header pipe, which simplifies installation and maintenance, as well as a digital indicator which shows pressure levels and water temperature to make servicing the systems more efficient. These factors, as well as lower lifetime energy use, are also likely to improve overall cost-savings.

Modular chiller technology is advancing all the time, as engineering knowledge develops and the market demands more sophisticated approaches to installing and managing chillers. They are easy to source, quick and simple to install, and meet the demands of government legislation around energy efficiency. For end users, they are a quiet and flexible product that can adapt to changing building requirements and environments.

Traditional chillers aren’t going anywhere, but for noise-sensitive, outage-sensitive, urban, space-restricted environments, it’s time to embrace the benefits of modular chillers.

ASDA House in Leeds is benefiting from energy-efficient cooling with the installation of ten Mitsubishi Electric e-series modular chillers, replacing its existing outdated system.

The site, ASDA’s three story headoffice, operates as the central hub for the company and houses several functions, including office and meeting spaces, cafeterias, and customer support teams.

The building needed a new, reliable, energy efficient chiller system to replace the existing McQuay and Trane units with shortest lead times possible and minimal disruption to the building.

ASDA House needed a chiller system which was able to meet the significant cooling demands of the building as efficiently as possible. As the company’s head office, ASDA House also needed its cooling system to be extremely reliable to deliver a comfortable working environment to the employees working in the offices.

Plug-and play A city centre location means the site faces access restrictions, making ease and speed of installation a crucial factor. With only an eight-hour window on a Saturday to remove the old units and install the new chillers, it was essential there was a modular solution that could work on a “plug-and-play” basis, sitting on the existing blocks and connecting to the building’s existing duct work. Following a consultation with Mitsubishi Electric, the team were keen to use e-Series chillers, based on the range’s efficiency credentials

and flexibility. ASDA worked with DDA Ltd consulting engineers and Yorkshire Building Services (YBS) installers to deliver 10 e-Series EACV-P900YA-N chillers, providing 900kW of cooling to the wing of the building.

The e-Series is designed with a common internal header pipe which helps to simplify the design, installation and maintenance of the range. It also helps to reduce space requirements, leading the e-Series to be the perfect solution in a restricted urban environment. Low noise levels were a key requirement for the same reasons: by using highly efficient components and a uniquely shaped heat exchanger within the chiller, the e-Series range offers market-leading low noise levels no unit exceeds more than 65 dB(A) from any one side. The e-series design also incorporates two high efficiency inverterdriven scroll compressors, allowing each unit to operate between 8-100% of full capacity. This broad operating range gives the e-Series exceptional part-load efficiencies, which is how the system will operate for the majority of the time.

An important reason for the selection of the e-Series was the product’s resilience.

This is delivered through the modular design of the system; and with over 20 compressors, if a single compressor fails, 95% of the peak load can still be provided without interruption.

It is available in 16 models offering cooling capacities from 100kW to 860kW and heating capacities from 100kW to 944kW. By delivering combined heating and cooling solutions, the Omicron considerably reduces capital, maintenance and running costs. It also helps to satisfy growing demand for more flexible solutions that can help the building services sector meet the government’s targets for reducing carbon emissions from buildings to net zero.

With the Omicron, there is no demand conflict between heating and cooling – as is often found when running separate chiller and boiler circuits – because the Omicron has in-built sequencing for load sharing.

The chiller can switch instantly into reverse cycle mode to operate as a heat pump depending on demand.

Built in heat recovery also ensures waste heat is captured and recycled to minimise energy use and the unit can be supplied

with inverter driven water pumps to further improve efficiency.

Decarbonisation The system uses lower refrigerant volumes than equivalent capacity variable refrigerant flow (VRF) and Hybrid DX systems, at less than 25kg per 100kW. “This is a great time to bring such an innovative solution to the UK market,” said Swegon’s cooling sales and product director Andy Legg. “We are entering a new phase of the heat pump market thanks to recent changes to government policy on the use of renewables and carbon emission reduction.

“The rapid decarbonisation of our electricity grid is making the environmental and economic argument for heat pumps increasingly strong at the expense of traditional fossil fuel driven boiler solutions.”

The latest adjustments to the standard assessment procedure (SAP) – used to determine the best technologies for

reducing carbon emissions from domestic buildings –strengthened the case for using heat pumps instead of boilers.

Other trends identified by Swegon that are driving demand for the Omicron include improved insulation, greater use of glazing – particularly in high-rise buildings – and the increasing amounts of IT equipment in office spaces. All of these factors are shifting the balance towards greater demand for cooling and reducing heating periods in UK commercial buildings. The Omicron makes use of the traditional 4-pipe approach but takes it to a new level by combining the heating and cooling technology in one unit.

“The decarbonisation of the National Grid is further strengthening the case for this kind of solution against traditional boiler plant,” said Mr Legg. “30% of UK electricity now comes from renewable sources and for the first time since the Industrial Revolution, Britain is obtaining more power from zero-carbon sources than fossil fuels.”

Recent improvements to heat pump technology means they are now even more suited to UK climate conditions.

“The Omicron system has impressed customers, with its ability to meet heating demand even at external temperatures as low as -17°C. “This product is a significant step forward for combined heating and cooling solutions,” said Mr Legg. “It builds on tried and tested engineering principles to deliver greater flexibility in line with the pressures on minimising energy consumption through increased efficiency.”

Carrier chillers have been chosen to air condition the high-end offices in the Royal Exchange in the City of London.

Contractor JSA Service led the project to install the two Carrier AquaForce chillers equipped with Greenspeed® Intelligence inverter drives.

Royal Exchange upgrades with AquaForce cooling

Two high performance Carrier air-cooled chillers with a combined cooling capacity of 1.17MW have been installed at The Royal Exchange in the City of London as part of a major refurbishment of premium office space in the iconic building.

Installed by contractor JSA Service, the pair of AquaForce® 30XAV-600 chillers equipped with Greenspeed® Intelligence inverter drives replaced the previous chillers made by another manufacturer which had proven to be unreliable. Carrier, a world leader in hightechnology heating, air-conditioning and refrigeration solutions, is a part of Carrier, a leading global provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies.

The Grade 1-Listed building, located opposite the Bank of England, has undergone a complete refurbishment of its upper storey high specification serviced office accommodation. A key element of the project was to replace and upgrade the building’s air conditioning to match the outstanding new environment, in order to deliver the highest indoor comfort for tenants.

Allan Wilkinson, managing director of JSA Service, said: “The client required a high efficiency solution that would deliver top quality comfort conditions and operate with low noise. Reliability and resilience were key. The Carrier 30XAV chillers provided an excellent solution, offering low noise, superior reliability and optimal efficiency, especially at part load.”

The 30XAV units are designed to meet all current and future requirements in terms of energy efficiency and operating

sound levels. This is achieved through the combination of proven best-in-class technologies that include: ° High-efficiency variable-speed Carrier twinscrew compressors; ° Variable-speed condenser fans; ° Novation® high efficiency heat exchangers with micro-channel coil technology; ° Mechanically cleanable flooded evaporator; ° Carrier’s new Touch PilotTM control system; As standard, the chiller can provide an evaporator leaving temperature down to 3.3 degrees Celsius, with proven operation for outdoor air temperatures ranging from minus 20 degrees Celsius to 50 degrees Celsius.

Due to logistics challenges on site, JSA Service had to completely dismantle the chillers to enable individual components to fit through a small access hatch. The chillers were then reassembled in position, connected up and the system commissioned.

Chris Bates, director, JSA Service, worked with the technical services team to deliver the project. “It was the first complete chiller disassembly and reassembly we’ve undertaken, necessitated by access issues,” Bates said. “The fact that it is a Grade 1-Listed building also required great care in the planning and execution of the project.

We worked closely with John Foster of Cooling Technology Limited, Carrier’s sales agent, who provided excellent technical support throughout the project.”

The project was completed and handed over to the client within four weeks, two weeks ahead of schedule. The building is now fully operational as one of the most desirable and iconic office locations in London, with a high quality air conditioned indoor environment to match.

Daikin steps up backing for reclaimed refrigerant Partnership with A-Gas forms important part of manufacturer’s environmental initiatives.

More than 500 delegates at the D1 Partner event in London heard Daikin UK announce a range of measures aimed at increasing the use of reclaimed refrigerant and promoting a circular economy within building services.

The moves are part of Daikin’s commitment to provide safe and healthy air environments while striving to make its business activities carbon neutral by 2050.

The announcements included the allocation of certified reclaimed refrigerant in selected VRV systems, the use of reclaimed refrigerant in Daikin’s Commission with Confidence service, and the launch of a new Reclaim with Confidence service in partnership with A-Gas. The first of these focused on the newly launched VRV IV+ systems and existing VRV IV S-series units, which from 2019 have certified reclaimed refrigerant allocated to them during production, meaning these units have zero impact on F-Gas quotas. The quantity of reclaimed refrigerant allocated to these units avoids more than 300,000 tons of CO2eq from being generated in the production of virgin refrigerant.

The new VRV IV+ range has been designed with a new compressor that delivers an average 15% increase in seasonal effciency over the previous range of Daikin VRV systems. As a result, it already exceeds the standards of the Lot 21 Ecodesign Directive, which is increasing the minimum effciency requirements for air conditioners over 12kW once again in January 2021.

Daikin UK also announced that its Commission with Confidence service – which offers refrigerant supply, system charging,

August | September 2019

Daikin reclaim.indd 36

Daikin UK managing director Angela McGinley

commissioning and optional monitoring, all for a flat rate – would also switch to using certified reclaimed refrigerant.

Exciting time The event also featured the launch of a new Reclaim with Confidence service, which is available solely to Daikin D1 Business Partners and D1+ Premium Partners, via A-Gas. To encourage uptake of the scheme, Daikin is offering its D1 and D1+ partners extra Business Development Fund rewards, based on the quantity of refrigerant they reclaim.

Daikin says that trials have shown that Reclaim with Confidence makes it quick and easy to recover refrigerant according to best practice, saving almost 70% of time and costs on site. During a recent reclaim in Bristol, the Reclaim with Confidence service

recovered 50kg of refrigerant in three hours total time on site, comparing with typically a day’s labour of a team of installers onsite. The service can be arranged for all refrigerants and Daikin says customers can be confident that refrigerant is recovered and reclaimed to AHRI700 standard for future use in the market.

Managing director for Daikin UK, Angela McGinley, said: “This is an incredibly exciting time for Daikin UK and proving our commitment to reducing the environmental impact of our industry. After launching Commission with Confidence last year, we are now able to introduce reclaimed refrigerant as part of this service, as well as launching our new Reclaim with Confidence service which will help to ensure a greater supply of reclaimed refrigerant re-enters the market. Together with the introduction of Certified Reclaimed Refrigerant Allocation in selected VRV ranges, Daikin is leading the industry firmly in the right direction of creating a circular economy.”

Daikin is striving to make its business activities carbon neutral by 2050 and says it aims to achieve this by: ° Promoting energy effcient technologies and energy management solutions. ° Adopting refrigerants such as R32 with lower global warming potential; developing next generation refrigerants; and recovering and reclaiming refrigerants in use.

Reducing the environmental impact of ° materials throughout the entire lifecycle of our products – from procurement and manufacture to recovery and reclaiming.

The quiet revolution now coming to a town near you Air conditioning installers have a real opportunity in the domestic market as we see changes coming to the way we heat our homes. But as Ben Bartle-Ross explains, it’s not just performance that you need to look at.

The way the nation heats its homes is changing rapidly and we will see heat pumps become dominant in the next 5-10 years as we strive to hit the zero carbon target set by government.

This presents a real opportunity for air conditioning installers who are already well versed in heat pump technology, whether they are installing air to water heat pumps or air to air versions.

Wherever you look these days, it is difficult to avoid hearing something about the ‘Climate Crisis’ and this is raising consumer awareness of our impact on the planet as never before.

At the same time, we are seeing more and more days of grid electricity coming from renewable sources, so the case for a switch to electric air source heat pumps is made even stronger.

It is true that gas is still the dominant form of heating and due to subsidies is still relatively cheap. However, heat pumps are now challenging oil heating with lower running costs, less CO2, less maintenance more convenience with intelligent, in-built, web-based controls.

Environmental awareness At the same time, we also see a growing awareness amongst the general public of the damage we are doing to our planet and this urgent need to act is starting to permeate into the public psyche.

Growing numbers of UK homeowners are interested in becoming more sustainable

This will see heat pump sales grow further with the government forecasting one million sales a year by 2030.

Couple this with ambitious zero carbon targets, along with calls for a ban on gas boilers for new homes by 2025, and we can see that the market is rapidly changing.

Within the next decade, the UK domestic heating market is going to look very different from today.

So there is a tremendous opportunity for air conditioning installers who already understand heat pump technology and how to get the best out of it, so, whether you are offering air to air, air to water, or a combination of both, you could do worse than ask the leading manufacturers about training courses and support for both technologies.

In addition to telling you what they want you to hear about their product, you should have the chance to ask them about performance, controls, installation and technical support.

The main thing to remember about a heat pump’s performance though (even the most basic one) – it will work best if properly designed and correctly installed.

Hush!

Make sure you ask about noise, too, because this is an area that will become

increasingly important as heat pump sales increase, to ensure that neighbours aren’t disturbed – which is why Permitted Development exists.

In the residential environment, sound is important because low sound output gives more flexibility in where a heat pump can be positioned.

That is exactly why we as a manufacturer have looked beyond performance and focused heavily on developing some of the quietest units ever available – A libraryquiet sound pressure level of just 45 dB(A) makes passing Permitted Development requirements much easier.

Another string Burning ‘stuff’ to keep warm is simply no longer viable in the long-term which means we have to find alternatives and we need them now.

As the production of grid electricity gets ‘greener’ by the day, the case for electric heating using heat pumps is made even stronger, and that is where modern, advanced air to water heat pumps are ready to step up with technology that is as reliable as a kitchen fridge.

There is a phenomenal market out there amongst the growing numbers of UK homeowners that are interested in being more sustainable.

So are you ready to join the renewable revolution and deliver reliable, sustainable heating?

A 100 ml bottle of press fitting lubricant has also been added. The company is continuously progressing the >B< MaxiPro range.

Richard Leigh, group deputy technical manager, said: “In every market that we have launched >B< MaxiPro demand has been strong and continues to grow. Every week we are training more installers and engineers who see the benefits of using this innovative product as a quicker-to-fit, reliable alternative to traditional brazing. As a flame-free copper press joint, there’s no need for a hot works permit and the risk of fire is eliminated.”

Unsurprisingly for a business that has been around since Louis Blériot flew the Channel and Selfridges first opened its doors, there have been many important milestones along the way for Conex Bänninger.

Few, though, can have had a more significant impact than the 2011 acquisition of parent company IBP Group by the IDD Group, a global supplier to the HVAC and sanitary markets, including IBP, headed by chairman and CEO Martin Tang.

The deal followed a challenging period for IBP, with several ownership changes, and the subsequent support and investment has enabled Conex Bänninger to build again on a proud history of industrial innovation.

Although the West Midlands-based manufacturer had produced traditional copper fittings for the ACR industry since the 1950s – and still does – it has gained a firmer foothold in recent years.

In partnership with Wieland it developed the K65 tube and fittings system for high pressure applications such as transcritical supermarket refrigeration systems. This was followed by the >B< MaxiPro flamefree press fit system, which was devised in 2012 and made its UK debut in 2017 after previously being introduced in Australia.

The system uses three-point press technology, where three presses are made, one each side of the bead and one compressing the O-ring. It is designed for use in systems with operating pressures of up to 48 bar.

At its UK launch in 2017, IBP Group CEO Mano Bakhtiari said his aim was to see press fit accounting for 50% of the ACR installation market within five years. If the target seemed ambitious it could be argued that Bakhtiari, of all people, deserved to aim high.

More than 30 years earlier, he had headed an engineering team at Triflow which developed a flame-free system called N-Grip, based on the patent application of inventor and designer Michael O’Leary.

It was launched in Ireland but a Board decision consigned it to history, as it was felt it would potentially conflict with existing products, only for a competitor to later enjoy success with a similar design.

The arrival of >B< MaxiPro, then, was a case of making up for missed opportunities and, as Bakhtiari says, there is a very different culture in the business today.

He said: “It seems inevitable the press revolution will go on; that press will

>B< MaxiPro was developed specifically for use in air conditioning and refrigeration applications. It is designed to be used up to a maximum operating pressure of 48 bar, with a maximum operating temperature range of -40°C to 121°C. It uses a 3-point press, with one press each side of the bead and one compressing the O-ring, providing a permanent, leak-free joint.

The significance of >B< MaxiPro made it fitting that trade journalists from across Europe and beyond were invited to the Conex Bänninger anniversary celebrations in Córdoba, Spain, where the system is manufactured alongside K65 and the traditional >B< ACR range.

The Andalucían city boasts a pretty strong history of engineering innovation in its own right. A 16-arch Roman bridge spans the Guadalquivir River, and the incredible structure of La Mezquita, which was built in 784 as a mosque and has served as Córdoba Cathedral since 1236, attracts visitors from around the globe.

That spirit of innovation is carried through to the 20,000 sq m IBP Atcosa factory, as plant director José Luis Jiménez explained. Established in 1975 with 15 employees, the workforce has grown to 240 despite increased automation and capacity has reached 250 million pieces per year.

A deep technical heritage means that all machinery and processes are designed and engineered within the IBP Group and the focus in Córdoba, as elsewhere in the business, is on: ° New product development ° Quality engineering and product control ° Customer service On a tour of the factory, we learned more about the drive to continuously improve all the processes to deliver efficiency, quality and service.

Most copper manufacturing takes place at the IBP Atcosa factory in Córdoba, which has an annual capacity of 250 million pieces

The remainder is in Poland, which is also home to the largest of four distributions centres (others are in Córdoba, Dubai and the global HQ at Kingswinford, UK).

Group commercial director Richard Darwin explored the entire range, which has resulted in more than 22 billion fittings installed worldwide. He also described recent applications including K65 at the Wanda Metropolitano stadium in Madrid, which hosted this year’s Champions League final, and >B< MaxiPro for a major upgrade at Luton Airport.

Mano Bakhtiari closed by saying that the challenge now was to stay ahead of the market by continuous improvement.

He said there would be significant capital investment year on year to enable the company to grow.

He also said it was crucial to recruit and retain the best people and would strive to achieve that by an increased focus on work-life balance and providing clear pathways for progress.

In a commemorative book charting the last 110 years, he said: “For more than a century, Conex Bänninger has re-shaped, evolved, renewed. Sometimes it has taken the lead. At other times it has taken steps to catch up.

“Thanks to the talents of many it has brought significant numbers of new products and services to our customers.

But while products and equipment are important, it’s people this business is really about.’’

It seems certain that innovation and individuals will remain at the heart of Conex Bänninger. After all, it has quite a history in that area.

Online training for installers Engineers and contractors will soon be able to benefit from a new e-learning module for >B< MaxiPro. The module is a feature of a new portal being introduced by the global manufacturer of fittings and valves that is dedicated to the system. It has already been launched in the UK and the USA, with similar portals for other markets due to be announced in the coming weeks.

Previously, engineers had be trained face-to-face, learning the correct method of installation to become a certified installer which brings with it the added benefit of extending the warranty on >B< MaxiPro products from one to five years (terms and conditions apply).

By logging onto the new portal and creating an account, they will have the option of online training plus access to videos, installation guides and technical information, project case studies and the opportunity to post questions.

The module includes a step-by-step guide, followed by questions to test the engineer’s knowledge, and access to a digital certificate upon successful completion.

Emma Baldwin, group marketing executive, said: “As a business, we are continually looking at ways we can add value to the first-class service offering we provide our customers. Since its introduction, >B< MaxiPro has become the pipework jointing solution of choice for many ACR engineers and with the new portal and e-learning module it means we can put all the information they require at their fingertips in an instant.”

Why tank pumps offer a robust and reliable choice

When installing either cassette or ducted air conditioning in a restaurant or gym project, a key consideration is which condensate pump to choose. With both environments having high levels of moisture in the air due to cooking and exercise, it’s essential to select a pump that can cope with high levels of condensate. Chris Forshaw, technical manager at Aspen Pumps, tells us what installers should consider when installing AC in these businesses and how tank pumps are the ideal solution.

Cooking food and pounding the treadmill both result in higher than normal moisture levels in the atmosphere, so when installing AC in restaurants and gyms there is more to consider than which type of AC unit to choose. Selecting the right condensate pump is an important factor. Condensate removal pumps give installation flexibility, allowing a pump to be fitted either in, on or above the AC unit, but different types of pumps have different capacities. Tank pumps are robust and reliable and can deal with large amounts of condensate, so in buildings where high levels of condensate are generated, a tank pump is up to the challenge.

Installation A tank pump that is easy to install and maintain is a great advantage for engineers, meaning the tank pump will perform to its optimum performance and

in turn help ensure the AC unit does the same. Manufacturers have designed the latest tank pumps with features that simplify installation and maintenance.

Water spills are particularly hazardous for installers working in a ceiling void, where live devices are installed, therefore the latest pumps, such as Aspen Pump’s MAX Hi-Flow, boast an Ingress Protection (IP) rating of 24, raising tank pump safety to a new level. IP24 means a tank pump is protected from touch by fingers and objects greater than 12 mm, as well as from water spray from any direction, making it totally splash proof – a real benefit for engineer safety during routine maintenance.

Operation also remains safe in the event of water leaks near the pump, helping protect the pump and so the AC system.

Another feature that simplifies and speeds-up installation of the latest tank pumps is a built-in spirit level, meaning engineers don’t have to balance a separate one on the tank pump, avoiding the risk of things being dropped. Some tanks pumps, such as the MAX Hi-Flow, have a red LED built into the lid that indicates the presence of power, helping to speed up fault diagnosis. The newest tank pumps feature a single screw quick-release reservoir, which means they can be serviced while the pump deck and motor are still attached to wall or rod mounts, helping engineers avoid dismantling the whole pump and reservoir water spills.

Silence When sitting down to an intimate dining experience, a noisy AC pump is enough to put anyone off their food. Until recently, tank pumps tended to be used in more industrial settings where noise was less of an issue but with the new low profile tank pumps enabling installs in areas such as restaurants and gyms, quiet running

is an essential. As a result, the new tank pumps have been designed to be not only low profile but also extremely quiet whilst still being able to handle greater volumes of condensate than other pumps, thus improving air quality in noise-sensitive applications that produce high levels of condensate. The MAX Hi-Flow tank pump is the quietest tank pump available on the market, with an operating noise level of just 44dB(A), thanks to a specifically configured motor and impeller system.

Low profile The latest compact tank pumps boast a shallow profile making them ideal for installations where space is limited, such as ceiling voids and cassette air conditioning applications, whilst still offering all the condensate capacity expected from a tank pump. The MAX Hi-Flow benefits from a lowprofile design, at only 134mm high, 144mm wide, by 285mm long.

System protection Tank pumps are known for their reliability, but to add even more peace of mind, the latest tank pumps can offer protection to the HVACR system itself. They interface fully, with their Normally Closed or Normally Open high level contacts, to any BMS or HVACR system, which means they can turn off an AC system if there is a troubleshooting problem, for instance if the condensate pump has not been maintained correctly.

So when installing AC systems in restaurants, gyms and other areas with high condensate removal requirements, tanks pumps tick all the right boxes for engineers and businesses alike. They offer a safe, quiet, robust and efficient way to remove condensate as well as being easy to install and maintain and provide a reliable solution, offering peace of mind to end users.

Late payment culture does not need to exist

In the first of an occasional series, a well-known industry figure gives a personal view on a topical issue. In this edition, we look at late payments and what action is needed to protect businesses.

When I sat down to write this article, I deliberated many times on the potential consequences that my words would have for those that read it. I work in an industry where late payments are commonplace.

So much so that our business now has the potential to achieve its first trading year in more than a decade with no bad debt. We see this as a major success. That isn’t good enough and is cause enough to write some strong words about the situation that our industry finds itself in.

I still remember my first experience of late payment. I could not compute why the agreed terms were not being adhered to.

Two months later the business experienced our first debt and it was a significant blow. We had effectively lent money to someone/a business because we knew and trusted them. They had been in business for 10 years. What could possibly go wrong?

We paid for that equipment and, in our eyes,

August | September 2019

Late payments.indd 42

“If you own a business and work within HVAC then it is almost certain that you have experienced some pain” it was our property. Everywhere we turned, we received the same answer: “tough”.

As a business owner, many of the conversations that I have with clients are with regards to financial matters.

The truth is that nearly all of my clients are experiencing significant issues with companies that pay late. Thankfully, over 95% of my clients pay within agreed terms, including those that have problems getting paid themselves. Keeping cash in their business is essential for them and this keeps them afloat.

If you own a business and work within HVAC then it is almost certain that you

have experienced some pain and have either had to fight to get paid, become dependent on late payers (which in turn potentially makes you a late payer), or have suffered from bad debts.

If you are reading this and are preparing to start a new business in the HVAC sector in the UK, the sad reality is that you will have to manage late payments and bad debt. It comes with the territory. A website developer can simply switch off your website if you don’t pay them within their agreed terms. Your utilities can be cut off, the Inland Revenue can force legal action with little warning and your solicitor can cease working on your behalf if you don’t pay on time.

A HVAC contractor cannot shut a site

Volume 5 No.5

18/07/2019 15:45

CO MMENT down if they have not been paid. If they threaten to leave site then they are in breach of contract and the client can simply employ another contractor to complete their work. Try to argue this in court and the HVAC contractor gets hit with multiple issues from their ex-client which can range from poor quality work on site, not completing a project on time, not following Health & Safety practice and not formally agreeing variations. There are too many variables for the typical HVAC contractor to defend themselves in a court of law.

It is endemic within the construction industry and the habit shows no sign of improving despite the recent collapse of Carillion and the problems encountered

by Interserve. One thing that these two companies appear to have in common is the reliance on government-funded projects. Do these projects not come with the promise of payment terms well below 60 days? In my experience, payments within 60 days are what makes industry and relationships work. Payments over 60 days are what makes industry and relationships collapse.

There is no excuse for late payments and there is a significant and moral difference between a small company not realizing that they have had an electric bill for £500 compared to the same offering a free of charge, interest-free loan to their client for the installation of a large air conditioning and ventilation project. The small utility bill carries a threat and the large loan carries fear. This is a culture that we need to change and we need our government to act urgently to enforce legislation that changes the way that contracts are managed.

1) Contracts should not be awarded to contractors that cannot finance the works. Companies with £20k of assets should not be awarded £250k projects.

2) Retentions need to be addressed immediately with legislation in place to work to a separate bank account type system.

3) Late payment legislation needs to be addressed further by government.

This has the potential to wield some power, but it will bring an end to any relationship and is too problematic to enforce. Speaking from experience, the

”An end-user should not be able to take delivery of a building where plant, machinery and equipment has not been paid for”

43

court does not offer you a pleasant experience even if you are successful and the time and complexity required to complete the process is prohibitive.

4) Implement a Considerate Payment Scheme. What power for the FM company that is a member of both a Considerate Contractor AND Considerate Payer schemes?

5) The T’s & C’s of the awarding contractor should not apply except for retentions.

The installing company purchasing plant and therefore providing a loan should have their T’s & C’s protected

by Government.

6) The government should implement legislation that protects the supply chain. In the event of a contractor bad debt where machinery, plant and equipment is on site, that equipment has been paid for by somebody in said supply chain. An end-user should not be able to take delivery of a building where plant, machinery and equipment has not been paid for. In this instance, the end-user may have unconsciously taken delivery of the building and someone, somewhere, has added the supplier debt to their bottom line. That is simply criminal and we have a reasonable right to expect our politicians and industry to protect us.

Late payment as a culture within business does not need to exist. Our industry needs to change but we cannot force change without help from the government. What business owner has the time to mount a one-man war?

Even a brief look through the Carters archives reveals plenty of evidence that this is a business which has never been afraid of change. The 74-year history of the Carter Thermal Industries Group – to give it its full title – is punctuated with examples of acquisitions, mergers and innovation.

When Carters built a new factory 15 years ago, the long-term goal was always to consolidate the group’s businesses into a single site. That vision has now become reality as Carter Synergy and Carter Environmental Engineers (CEE), plus head office staff, take up residence alongside Carter Retail Equipment at Lea Ford Road.

The consolidation allows the closure of the sites at Redhill Road, previously home to head office and Carter Synergy, and Hamilton House, which housed CEE, and the company hosted an open day for customers, guests and ex-employees to mark the beginning of the next chapter of the Carters story.

Group chairman John Scott said: “We built Lea Ford Road as a specialist factory for case manufacturing and the objective was always to move the rest of the group, chiefly Carter Synergy and CEE, onto this

Significant expansion “We then got some senior people at Carter Retail Equipment (CRE) and CEE to say what we could move into Lea Ford Road. Our priority was always that we didn’t let our customers down. Whatever we do cannot mean that we miss a delivery of a case, an engineering project or a cooling tower.’’

The service desk has been consolidated, with a significant expansion establishing Glasgow as the principal call desk, with a smaller operation at Lea Ford Road. There has also been a concerted push to keep contract engineers on. In addition, the dust extraction arm of CEE was recently sold to fellow Midlands manufacturer, Filtermist.

Even so, Carter Synergy managing director Chris Hufflett estimates the move has still seen close to 100 people moving to Lea Ford Road, either in the new open-plan office block or the factory itself, along with heavyweight equipment including a laser unit, welding bays for CEE and Franklin Hodge Industries, plus fabricating kit.

As any recent visitor to Birmingham can testify, the city is currently undergoing significant changes and the level of development has had an indirect benefit

It had previously not been possible to undertake CO2 refrigeration training in Scotland or the north of England. Tony Deith, CO2 training manager at KB Refrigeration, arranged for several of the senior staff and lecturers from Kelvin College to attend a bespoke training session at the Carter Synergy training facilities at Redhill Road. Gary Downes delivered the training and all three attendees from the college were brought up to the required standard.

Liam Noble, head of the refrigeration department at Kelvin College, said: “I would like to thank KB Refrigeration and Tony Deith for organising the CO2 training at Carter Synergy headquarters in Birmingham. I hope that the special relationship that we have with KB Refrigeration continues to grow and look forward to the future.”

Future generations Separately, a decision was reached within Carter Synergy to donate a trans critical CO2 training rig to the college. This enables the college to provide training for future generations of refrigeration engineers in Scotland and marks a first for the region.

Tony Deith said: “We have been working quite closely with the college for the last two years or so and all KB refrigeration apprentices go through the college. The main issue we faced was the cost of having suitable CO2 training delivered to our Scottish and northern region engineers in the UK due to the lack of any training facility in Scotland.

“We identified that due to internal changes to our head office and training centre we would have to move this to Hereford.

The consensus was that one of the two packs could be moved to Hereford, but not both, so the decision was made to gift this to the college, which would provide them with a training rig and allow them to then offer a certified and high level training course up to City & Guilds level 3, rather than a simpler “appreciation” level course.

“With the lecturers being aware of the impending changes to the training they then wanted to gain the same level and so we worked with them to have all four trained and certified at our training facility in Birmingham.’’

REFRIG ERATIO N exciting. Historically, the big industrial cold stores have used ammonia but now, more and more, trans critical CO2 is taking its place. We are pushing that through our partnership with Green & Cool. CO2 started in main store supermarkets and now goes all the way from the convenience sector upwards to distribution / warehousing and that is very exciting for us. In August of 2017, for example, Carter Synergy delivered a world first with the installation of a Green & Cool rotary pack solution for the Tesco Express store at Shaw.

“Moving forward we are currently working on a project which has seen us partner with our client Ornua Foods, Armstrong Fluid Technology & Green & Cool to deliver an exciting HFC replacement solution for their process chillers.’’

There are growing opportunities, also, in the export market. From “a couple of million in 2016’’ overseas sales will probably make up around 15% of the business this year. America is by far the biggest market, but Carter Retail also sells to Australia and Ireland.

John Scott noted: “We are seeing that the American supermarket business is going through a fundamental change. We have always associated them with the huge out-of-town places with big freezers. We are seeing a movement, as we have seen in the UK, to a small store format. Target, for example, have a major programme of

small format stores bespoke to the locality.

Similarly, HEB in Texas is also undergoing a refresh of their stores and really altering the look & feel of the space they have.

“For the last five years most of our business has been with low GWP refrigerants. America is a long way behind in some areas but some of these supermarket chains are looking to go green. They want the look, feel and quietness that we can deliver with our cases, and they appreciate our levels of customer service.

New markets “The route we have taken in the UK is really important because it puts us in a great place. We had a great standard range of cases which we have be able to adapt to individual customer and market requirements. Our focus this year, with our five test labs, is on how we can further develop our standard range and ensure it’s the most energy efficient case on the market. That is critically important to the UK market but it is important for our export markets as well.

“Our exports complement our UK sales, giving us essential economies of scale.

We are aware there are very few UK-only suppliers left. We have to export but you can only do that if you are doing things right for your home market. Our exports have only been possible because of what

47

we have done in the UK and we always have our home market in focus.”

The group employs around 920 people and turnover last year was £130 million, with the supermarket sector accounting for around 70-80% of that business and a pretty even split between service, cabinets and contracting.

“Supermarket refrigeration is the heart of our business,’’ said John Scott.

“We have diversified into new markets, into industrial, but we have to be the UK supermarkets' preferred refrigeration company. Preferred doesn't mean we are the biggest but I want it to be that whoever thinks of cabinets, coldstores, contracting, design, packs… they think of us first.

“The trigger for this open day was the consolidation. There were a lot of people in the room who spent most if not all of their working life at Carters and some of it was about giving them respect for the part that they have played. Our people have always been a key part of what we do and how we perform.

“I have always assumed that the customers and employees knew what we did, but that’s not always the case. People are genuinely surprised by how big and how diverse we are.

"Looking through the literature to put something like this together, it's hard not to be nostalgic, but the message is that we have always changed.’’

J & E Hall commercial condensing units have been used in a major project to futureproof facilities for the fishing industry at Whitehaven's historic harbour in Cumbria.

The units are providing the cooling for three cold rooms in the fish hall at the North Quay inner basin, which is used mainly for the short-term storage of catches by boats operating in the Irish Sea. The vast bulk of the catch is shellfish, with the remainder flatfish and whitefish. Bait is also stored on site.

The refrigeration equipment, operating on R449A, was installed by Carlisle-based Refrigeration (Mitton) Ltd. The installers were chosen by main contractors Stobbarts, of Workington, who were appointed to carry out the work by the Whitehaven Harbour Commissioners. The J & E Hall units were two JEHS 0250-B2-M3 and two JEHS 0200-B2-MS Fusion Scroll commercial condensing units supplied by refrigeration equipment wholesaler FSW. The compact and efficient Fusion Scroll units are said to be the ideal solution for commercial refrigeration sectors where noise, size and reliability are paramount. Housed in a cabinet made of electro-galvanised mild steel with an anti-corrosion treatment and coated in baked polyester powder paint, they are able to withstand the most severe weather conditions.

The integral IP54 rated control panel provides further protection to all essential electrical components. All units are acoustically lined. The Fusion Scroll units house the extremely efficient Copeland scroll compressor.

All components are fitted during manufacture to save the installer time and money and are available for medium and low temperature applications.

Refrigeration (Mitton) operates throughout north west England and south west Scotland and employs 11 people. Alex Mitton is director of the family business started in 1950 by his grandfather, Alfred Mitton. At Whitehaven the cold rooms measured 4.4m x 4.1m, 4.1m x 4.1m and 4m x 3.6m. The freezer room measured 3.5m x 3.6m.

Smooth and efficient Alex Mitton said: "The initial part of the job was to dismantle the existing cold rooms, decommission the refrigeration systems and remove them from the site. The next step was to carry out groundworks to prepare for the construction of the new panelling and goal-post protection. The new cold rooms were installed and we then added all the new refrigeration equipment and the control panels.

“Part of our contract was to supply and fit new electrical supplies which a trusted local electrician did on our behalf. The final part

was to relocate an ice-flaking machine to operate above the new freezer room which would allow the flaked ice to drop via a chute to storage bins within the freezer room.

“The original equipment featured ceilingmounted mono bloc systems around 15 to 20 years old. We specified split systems because there was a concrete pad above the rooms which would bear the weight load. Switching the systems on to separate condensing units on a plinth made it a lot safer to work on and service – and a lot more accessible.

"It was a very smooth and efficient project – something to be proud of – and from our point of view I don't think the job could have gone any smoother. We love the J & E Hall equipment. We have used it for years and I cannot recall any issues. It's always been readily available for jobs if you get an order and need to move quickly. The sales and technical support from FSW and from J & E Hall were fantastic as well."

Whitehaven Harbour Commissioners chief executive Celia MacKenzie explained that the use of the fish hall had declined over the years due to changing commercial fishing practices. She said: "We still needed the chillers but by the time the compressors had got to about 14 years old they were gasping their last breath and we had to do something.”

“We really feel we have future-proofed the facilities. These developments will benefit residents and visiting fishermen.”

The Ethos system from STS reduced carbon emissions by 310 tonnes per year for The Ice Co Storage & Logistics

Ethos efficiencies rewarded Energy management system earns award for STS.

Star Technical Solutions (STS) and The Ice Co Storage & Logistics won the Partnership Award at the Temperature Controlled Storage and Distribution Awards in Peterborough.

Star’s Ethos energy management system has reduced carbon emissions by 310 tonnes per year at just one of The Ice Co’s sites, in addition to saving the customer over £100,000 annually on electricity. The company now plans to install Ethos at other distribution centres to further reduce its carbon footprint.

Anne Flanagan, business development management at STS, said: “We’re delighted to accept this award for our ground breaking project installing Ethos for The Ice Co Storage & Logistics at its West Yorkshire distribution centre. It is a great case study and example of just how much impact our plant optimisation solution can have on existing refrigeration plants. The company has significantly reduced its annual energy spend and carbon footprint by following the system’s targeted maintenance.”

STS, the technical advisory service of Star Refrigeration, describes Ethos as a

unique concept. The consultancy led energy management software plays an important role in helping end users understand the energy consumption of different parts of their plant and the cost implications of inefficiencies. Ethos identifies where savings can be made and makes recommendations, such as altering plant settings or making immediate maintenance regime changes. Some recommendations may require capital investment for a bigger percentage loss in energy usage, but many proposals are simple control changes such as altering the condenser fan sequencing to deliver energy savings.

Joanne Webster, group compliance manager at The Ice Co Storage & Logistics said: “We are happy to be used as an example of the fantastic savings that can be made through the quick and easy installation of Ethos – in both energy savings and carbon emissions.

“Many plant users know the system is probably not running as efficiently as it could, but Star Technical Solutions have the knowledge and experience to identify exactly where savings can be made, and many of which are with minor unnoticeable changes in system operation.”

”It is a great case study and an example of just how much impact our plant optimisation solution can have on existing refrigeration plants.“

Star ice rink.indd 50

A new ice surface installed at a curling rink in Edinburgh by Star Refrigeration has reduced the energy consumption of the refrigeration plant by 9%. Home to 1600 members and 80 clubs, the rink at Murrayfield Curling required attention and Glasgow-based Star was appointed principal contractor.

The ice rink floor had become uneven and inefficient, causing irregular formation and thickness of the ice. Star provided technical support and guidance for the floor replacement project, knowing that the thicker the ice, the harder the cooling plant has to work to freeze the ice surface. This in turn has an impact on the curling conditions and energy consumption.

Star designed, manufactured and installed a glycol pump skid, fitted the composite floor and laid two layers of overlapping insulation. Star engineers were also responsible for the installation of a header system designed to supply the cold and warm glycol mats, as well as the heat recovery pump skid to feed the latter and all associated pipe work.

The consistent level of ice is thinner, delivering a level playing surface for curling at the desired temperature without requiring extra work from the refrigeration plant. The new plant has reduced the site’s energy consumption by 9%.

New energy-efficient system to meet growing demand for chilled products.

JD Industrial Cooling (JDI), part of the JD Cooling Group, has designed and installed a complete energy-efficient ammonia and glycol cooling system to enable potato farmer Albert Bartlett to meet the demands for its new chilled potato products.

Supplying over 20% of the UK’s fresh potatoes and to the UK’s major retailers, Albert Bartlett has invested in its Airdrie production site as the business grows.

JDI was tasked with providing a new central temperature control system for the whole process factory, including the refrigeration plant room, storage facilities and packing areas.

JDI’s solution features a Sabroe low temperature screw compressor, three Sabroe high temperature reciprocating with a speed range of 500-1500rpm, evaporative condenser, two spiral freezers to deliver mashed potato in sealed trays, 16 glycol air coolers and three end suction glycol pumps, each with a flow rate of 242m3/hr.

Rejected heat from the drive systems in the refrigeration switch room needed to be managed, with another glycol air cooler sized at 20kW installed to ensure that a room temperature of 20°C to 25°C is maintained.

Equipment capable of operating at very low temperatures was a key consideration of the brief as well as the hygiene associated with food production.

JDI manging director Mark Culley said: “This was an interesting project, providing a full-service solution that meets the needs of such increased demand for chilled potato products. Committed to helping clients through all their cooling system needs, we aim to truly understand the business and work in partnership to deliver the most effective solutions.”

In collaboration with JD Cooling Group’s other business units, the automation system consisting of two network protocols: Ethernet and Profibus, was designed and installed by JDI Controls. As JDI standard, the electrical automation system has been designed to not have a single point of failure and specific software that helps to optimise the running conditions of the complete system. www.jdcooling.com

Why recovery is the future A-Gas Rapid Recovery technical and training manager Roger Smith on the crucial role refrigerant reclamation is playing in the industry.

A-Gas has been working hard to extend its range of reclaimed gases available to customers. We have invested heavily in expanding reclamation facilities in the UK and in Holland as the industry rises to the low GWP challenge.

We have built two new tanks at our site in Portbury near Bristol to increase our storage capacity for reclaimed refrigerants.

A-Gas also has a base in Holland at Eygelshoven which houses a new refrigerant reclamation facility and this is expected to make an impact on supplies later this year.

Momentum is with A-Gas Rapid Recovery after its launch in Continental Europe at the Chillventa exhibition last year. This quick and easy way to recover refrigerant on site at short notice has impressed customers at home and abroad. They have told us that they like the way it saves time on site and reduces costs, while helping to maintain business as usual for the customer.

Purified and guaranteed

"Reclaimed refrigerant has been reprocessed by a licensed facility to the industry standard AHRI 700 to match that of virgin product.â&#x20AC;?

Refrigerant recovery is beginning to play a bigger role in our industry as the 2020 ban on the use of high GWP virgin refrigerant (above 2500 GWP) looms. One of the questions we are often asked at A-Gas is what is the difference between recycled and reclaimed product? I will explain how they differ. Reclaimed refrigerant is a gas that has been reprocessed by a licensed facility to the industry standard AHRI 700 to match that of virgin product. It is refrigerant that is purified, certificated and guaranteed.

A refrigerant that has been recycled is an uncertified product that is being returned for use on the same site and has not been moved between premises. Itâ&#x20AC;&#x2122;s a used refrigerant that should have gone through a basic, on site, cleaning process, normally carried out by the contractor completing the work.

Unprocessed refrigerant recovered from a system cannot be stored on site for longer than a year due to issues

around landfill. As soon as you move it from the site – unprocessed or recycled – it is classed as hazardous waste and must be sent, with the appropriate legal environmental paperwork, to a licensed facility for reprocessing or disposal.

This is where A-Gas can make a difference for contractors and end users.

We process the waste refrigerant back into AHRI certified product and this helps to reduce the short-term impact of the F-Gas phase downs on the industry. We are reclaimed refrigerant specialists and don’t sell recycled gas at all.

Refrigerant sent to our reprocessing centres becomes fully reclaimed product and is returned to the market in line with the AHRI 700 standard.

At Portbury and Eygelshoven used refrigerant undergoes chemical analysis, is cleaned of contaminants and goes through our separation plant to produce a product that matches that of virgin refrigerant requirements.

You should be aware that a product

can change composition through its life if the system has experienced leaks. This is particularly true for blends of refrigerants, such as the R407 family. Installers should act on the side of caution when looking to re-use recycled products that are not single component refrigerants. A-Gas offers a refrigerant analysis service at its custombuilt lab in Portbury where it can confirm a refrigerant’s composition, purity and help relieve that uncertainty.

Reassurance for contractors Our job is to ensure that our reclaimed refrigerant meets the same standard as virgin product. This means it is reprocessed to AHRI 700 standard and can be sold to be used in other systems. When buying reclaimed refrigerant you know it has been returned to the same standard as virgin material. This gives reassurance to the contractor and the end user and in turn ensures it performs as it should.

Installers can be reassured that reclaimed refrigerant will not lead them to breach

53

the F-Gas Regulations. Our investment in reclamation facilities highlights the commitment we have to providing the industry with the capacity and infrastructure to support the F-Gas phase downs.

Our new separation equipment will enable us to reclaim mixed refrigerants from customers across Europe. This type of waste has changed over the years as refrigerant mixtures get more complicated and we start to see much higher quantities of mixed gases.

Several different refrigerants combined together in one mix sets us new challenges and without separation technology it is almost impossible to return the gas to the same kind of quality as virgin material.

A-Gas reclaims thousands of tonnes of refrigerant a year across the globe and investing in new reclamation facilities will ensure that we continue to be one of the world’s leading reclaimers of refrigerants.

Freezing out illegal imports Sarah Hughes, Europe, Middle East, Africa and India commercial director for Mexichem’s Fluor Business Group, discusses how to tackle the illegal trade in refrigerants.

The best way to make something appealing for the black market is to make it highly regulated. As fluorinated greenhouse gas (F-gas) regulations have restricted supply of higher global warming potential (GWP) refrigerants, we are seeing an increase in illegal imports. But how did we get here and what can the industry do about it?

The landscape The F-Gas Directive, introduced in 2006 and updated in 2014, aims to reduce environmental damage from commonly used gases. Within this directive, hydrofluorocarbons (HFCs) have come under particular scrutiny and the legislation has had a huge impact on the supply of these gases into the EU. Current EU targets mean that the UK has committed to phase down HFCs by 79% by 2030. In the event of a no-deal Brexit, the UK has committed to regulating F-gas and ozone depleting substances (ODS) and the Environment Agency has also suggested that it will transfer most of the requirements of EU regulations into law.

So now when the UK has left the EU, any business placing more than 100 tonnes of Co2 will need a UK HFC quota.

A 2018 report from the Environmental Investigation Agency (EIA), indicates that Europe is facing what it describes as “a substantial level of illegal use and trade in HFCs”.

According to the EIA, as much as 16.3 million tonnes of carbon dioxide equivalent (MtCO2e) of bulk HFCs were illegally placed on the market in 2018.

This represents more than 16% of the 2018 quota and, says the report, doesn’t take into account illegal imports of HFCcontaining equipment and illegal HFCs that are “undoubtedly” being smuggled under the radar of customs. In some cases, HFCs are being mixed with lower quality,

counterfeit or illegally imported HFCs. A recent Environmental Audit Report, UK Progress on reducing F-gas Emissions, suggested that the government should ensure that adequate resources are allocated to monitoring illegal activities, especially online and that only qualified persons handle F-gases.

In April this year, German MEP Jo Leinen requested clarification from the EU Commission on steps being taken to tackle this illegal refrigerant trade. Leinen suggested that much of the trade is coming from Asia and asked that the EU work with its Asian counterparts to identify and track these illegal exports. And in 2018 Lithuanian MEP Rolandas Paksas told the EC it was making a “nonsense” of the F-gas quota system over its failure to tackle the issue of illegal F-gas imports. He also suggested the Commission should impose stricter controls at EU borders.

What’s the impact?

This illegal trade of HFCs is having a severe impact on EU emissions targets, government tax revenues and damaging legitimate businesses who are losing out to people offering illegally imported refrigerants. The EIA says: “We are concerned that the illegal trade along with stockpiling of HFCs in 2017 has produced a false sense of security in terms of availability of HFCs to meet the phase-down steps from 2018 onwards. Future quota cuts will be difficult to meet unless the transition to low-GWP alternatives is accelerated.”

At a micro-level, businesses who use these illegal refrigerants are putting their employees and customers at risk. Plus, if found to be using an illegal HFC product, businesses could face penalties such as fines, criminal prosecution, and a longlasting impact on a company’s reputation.

What’s the solution?

European Commission actions so far have included customs controls workshops for custom and F-gas experts, which include dedicated custom codes for bulk gas and equipment and checks on the registrations of companies for HFC import and export.

The EC is also creating an IT system – slated for 2020 – to allow for the tracking of all incoming related shipments. Several EU member states are working on tracking shipments, requiring written permission for import and creating databases for all relevant imports and working with the EC on how the data it collects can be used to support their own surveillance.

In addition, the EFCTC (The European Fluorocarbons Technical Committee) has sponsored an illegal trade action hotline allowing individuals to report alleged suspects offering suspect HFC. The increase in illegal imports affects us all, therefore the whole industry must work together to ensure the right measures are put in place. www.mexichemfluor.com

If you have become aware of incidents relating to smuggling, mislabelling, counterfeiting of F-Gas products or the use of illegal canisters, contact the EFCTC hotline:

LEAK DETECTIO N

55

Complete solutions Scott Davies, UK Sales Director for JAVAC UK, explains why JAVAC is the one stop shop for HVAC leak detection equipment.

Leak detection is always a tricky job.

Engineers never know what they are going to be faced with until they arrive at a job and the reality can massively vary.

From public thoroughfares where access is limited, to tight spaces and dark ceiling voids which don’t lend themselves to easy leak detection, more often than not, time is of the essence and a reliable method of leak detection is essential. JAVAC understands the challenges faced by busy engineers and is proud to supply a complete solution for HVAC leak detection with a method for every application.

For those who favour electronic leak detection, JAVAC offers an impressive range of electronic leak detection devices offering consistent and accurate responses. The Tek-Mate leak detector features soft touch switch-off, high/ low sensitivity and an automatic contamination adjustment, perfect for detecting a large leak down

to the smallest pinhole. The D-TEK Select is F-Gas compliant with ultra-high sensitivity to all standard refrigerant gases and uses an infrared sensor with a 1gm/yr detection rate which will not weaken over time.

The Atex-approved Gas Mate is twice as sensitive as its nearest competitor with adjustable sensitivity to help pinpoint leaks fast, as well as auto-zeroing for ignoring background gas levels in a leak test area. Suitable for R32 and all standard refrigerants and hydrocarbons, this clever device also detects natural gas, propane, butane, cyclopentane, ethane, ethanol, isobutane and ammonia.

Offering 1-2 year guarantees, as well as JAVAC’s outstanding 5* service and support, these devices are a staple piece of kit. The range features F-Gas compliant devices as well as offering ultra-high sensitivity and simple LED displays.

Awkward places

The D-TEK Select uses an infrared sensor

Alongside the traditional electronic leak detection systems, JAVAC also offers Spectroline - a wide range of products developed to pinpoint the exact source of every leak in any air conditioning or refrigeration system, particularly in hard to reach and awkward places. The range includes OEM-approved fluorescent dyes, sealants, high performance leak detection lamps and kits designed to meet the requirements of HVAC professionals.

Founded in 1955, Spectroline is the world’s leading manufacturer of ultraviolet equipment and fluorescent materials. With accreditations from industry leaders such

The Gas Mate features adjustable sensitivity

as Daikin, Bitzer, Fujitsu, Carrier and even Copeland, Embraco & Tecumseh, HVAC engineers can be assured that Spectroline will cause no damage to HVAC systems. The dyes do not need to be flushed out, meaning they can safely remain inside systems to find future leaks, saving time on future jobs.

The fluorescent dyes in the Spectroline range are proven to be the fastest, easiest and most cost effective way to find hard to reach leaks in awkward places and confirm what repairs are needed. Once a leak is identified, installers can inject Cool Seal to seal the leak. Cool Seal works with all popular refrigerants and oils and is safe for system components and recovery equipment. The product can be easily injected into systems without the need to turn the system off and can add years to older, out-of-warranty AC&R systems that leak small amounts of refrigerant.

JAVAC have leak detection covered as part of every preventative maintenance programme, with solutions for every job, to suit every engineer.

Spreading the word

David Todd joined PACAIR, Bacharach and a roomful of consultants to learn about refrigerant leak detection options.

Nick Ryman urged consultants to look beyond compliance for leak detection

PACAIR’s determination to provide complete solutions to the air conditioning industry has led to the beginning of a conversation with consultants about making the right choices when it comes to refrigerant leak detection.

In addition to the distribution of Mitsubishi Electric, LG and Toshiba equipment from its offices in Hemel Hempstead, the North West and Midlands, PACAIR also provides a full design service and decided to organise a bespoke gathering for consultants alongside its leak detection partner, Bacharach.

PACAIR specification manager Nick Ryman said the aim of Mitigating the Impact of Refrigerants was to look beyond leak detection in terms of compliance and focus on how environmental effect can also be reduced, at the same time as improving efficiency and performance for end users.

August | September 2019

Pacair LD.indd 56

He said: “We wanted to start a discussion around leak detection because at the moment around 99% of what we do is based on legal compliance. That is clearly very important but we also wanted to show how we can minimise the environmental impact of refrigerants, as well as cutting maintenance costs and running costs.

“Systems utilising leak detectors with lower sensing points could be losing significant amounts of refrigerant over time, so there is the expense of replacement refrigerant. In terms of performance, all test data from manufacturers relates to systems charged with the right amount of refrigerant. Leaks can mean that systems can’t perform as intended at the published efficiencies.

“We learnt things as well, thanks to Bacharach, and there were definitely some thought-provoking discussions.’’

Nick opened the event with an overview of the EU F-Gas Regulation and the ongoing phase down of HFCs which began in 2015 and will cut availability by 79% by 2030.

Stationary refrigeration equipment running on HFCs with a GWP of 2500 or more will be banned from January 2020, while centralised refrigeration systems for commercial use with a capacity of 40kW or more that use F-Gases with a Global Warming Potential (GWP) of 150 or more will follow from 1 January 2022. Single split air

Educating customers “This wasn’t about selling more leak detection equipment, it was about helping to educate our customers. What consultants want is to talk to people who can give them honest, independent advice.

Hopefully this event delivered that. We may not see any impact until a year or two down the line but we wanted to start the conversation.

LEAK DETECTION conditioning systems containing less than 3kg of F-gases with a GWP of 750 or more from will be phased out from 1 January 2025 He said that with legislation around F-gases becoming more stringent, manufacturers are looking at alternative solutions, and added that the environmental impact of refrigerants can be controlled through the right leak detection system.

Bacharach sales director Karl Roberts told delegates the key drivers for leak detection systems included safety, environmental and economic considerations.

He explained how the F-Gas Regulation requires the mandatory installation of fixed leak detection systems to monitor refrigerant circuits containing charges equal to or greater than 500 tonnes equivalent of CO2 (CO2 e) of HFC and HFC/ HFO blends. Installation of fixed leak detection reduces the required frequency of manual leak checks.

The recently revised Guidance Note 20 from the Institute of Refrigeration, meanwhile, says that refrigerants have a “practical limit” expressed in kg/m3 as specified in BS EN 378. If the charge of a refrigeration circuit in kg divided by the room volume in m3 exceeds the practical limit, then additional safety measures such as automatic detection will be required.

Potential advantages Karl also explored why leaks happen, from design and installation issues including poor brazing techniques, metal to metal contact and improper support; wear and tear because of vibration, thermal expansion or corrosion; or maintenance problems such as improperly tightened fittings or missing valve caps and seals.

Colin Anderson, Bacharach’s European sales distribution manager, went on to explain how to monitor for leaks through point detection/diffusion systems, or the more sensitive aspirated options.

HGM-MZ multi zone system

The MGS-400 gas detection series is used to detect large leaks and has a typical alarm range of 1000 parts per million (ppm).

The MVR-300 VRF system, meanwhile, is for use in occupied spaces, including hotel rooms or apartments, where the practical level could be exceeded.

Aspirated systems such as Bacharach’s HGM-MZ multi zone, meanwhile, draw samples from sensing points to the central unit and can detect much smaller leaks, with an alarm range of 1 ppm. The tubes to take samples can be split to 32 or even 48 points, with a maximum run length of 1200ft from central panel to sensing point. Among the potential advantages of this option are early detection, leading to a smaller amount of refrigerant required to top up leaking systems, and improved performance due to equipment being fully charged.

Karl Roberts said: “It is great to work with PACAIR on this project. We want to

educate clients with the range of benefits available. They can then decide if leak detection is just about compliance, or they want more than that.’’ ° PACAIR has plans to stage a similar event for consultants later in the year, looking at the potential advantages of community air source heat pumps.

Rising to the challenge

to pay for it. With the TQ31, we wanted the best possible product for a lower cost. We have definitely been pleasantly surprised with the way things have gone, particularly as the TQ31 is R32-ready.’’

TQ is ISO 9001 certified, the international standard for quality management systems.

It guarantees 100% traceability and the company believes that a large part of the success of the TQ31 stems from the fact that it is designed and manufactured in the UK. The company is very proud of the level of testing and quality standards for every unit that leaves its HQ, just minutes from the M1.

TQ moved to its current home just over two years ago and the workforce of 18 is made up of seven production staff, four service engineers, one R&D engineer, two accounts staff and two directors.

They are joined by the sales team of Mark Scott, who has been with the business since 2016, and Gary Allen, who joined from Parasense in May this year.

An impressive training room hosts one of Fujitsu’s regional training academies and also enables TQ to stage events such as the recent IOR Cool Talk, which attracted around 50 delegates.

“The move has worked out really well for us,’’ Gary Hall said. “It’s a much better fit for the business.’’

A random question helped to open up important new markets for gas detection specialist TQ Environmental. David Todd visited Yorkshire to find out more.

Mark Scott and Gary Hall of TQ Environmental

It was a chance enquiry some four years ago that provided the springboard for TQ Environmental to establish a significant foothold in the air conditioning refrigerant leak detection market.

Gary Hall, managing director of the Wakefield-based business, recalls: “A business contact got in touch and said they were having issues with their existing product and they were looking for an alternative to what was out there.’’

Part of the problem for the customer was that the sensor could be triggered by hairspray or deodorants, a particular concern for systems in hotels.

As a result of that initial query the TQ31 was developed and launched with a timed delay to offset the aerosol issue. More

than 3,000 units were sold last year, with installations in hotels, offices and high-end residential developments.

TQ was not a newcomer to the air conditioning sector, having previously won orders through the TQ4200 infra-red system which is also suitable for some refrigeration applications, but it accounted for a small part of the business five years ago and there is no doubt the arrival of the TQ31 opened up new opportunities.

Gary Hall explained: “We were always viewed as a high-end manufacturer, probably because of our involvement in marine monitoring systems and industrial refrigeration. We could offer a solution before but the cost of a sampling system meant people were not always prepared

HOW IT WORKS The TQ31 is designed as a single point, self-contained unit but can be connected to a TQ32 area alarm panel, which enables group monitoring of individual rooms for common refrigerants used in air conditioning systems or CO2 build up. Resistant to cross-sensitivity from hairspray and deodorants so can be used in hotel or office applications. A single alarm panel will typically monitor one or two floors depending on the number of sensor needed. The 3-digit LED display shows individual room numbers.

Configurable alarm outputs can provide plant trip signals and alert the reception desk, via an optional TQ35 indicator panel or third party alarm.

Carrier launches new water-to-water range Monobloc aimed at medium to large applications, says manufacturer.

Carrier’s new AquaSnap 61WG water-to-water heat pump

Carrier has launched a new water-towater heat pump for harnessing energy from rivers, lakes and industrial process applications that can deliver high temperature water up to 65°C for sanitary use or radiator heating The Eurovent-approved Carrier AquaSnap 61WG monobloc water-to-water heat pump is available in six sizes with heating capacities ranging from 29kW to 235kW at typical water conditions of 30/35°C, or 26kW to 200kW at higher temperature water conditions of 55/65°C. Carrier says it is designed for medium to large commercial applications requiring high temperature sanitary hot water, such as hotels, hospitals, universities and leisure facilities.

Alternatively, it can be used for heating with traditional radiators appropriately sized for up to 50°C, in line with current industry best practice guidance.

The heat pump is designed to replace or augment traditional gas boilers, or for use off-grid where buildings are currently reliant on oil-fired or electric heating. The system has a Seasonal Coefficient of Performance

(SCOP) of up to 5.05 (at 55°C). This means that over a typical operating season, it can deliver more than five times the electrical power it consumes in the form of heating energy as a result of harnessing and upgrading low level waste heat.

Easy installation David Dunn, Carrier UK managing director of sales, said: "There are many opportunities in the UK for harnessing energy contained in natural water sources or from output from industrial processes.

However, it is technically challenging to ensure the low level heat from these sources can be upgraded sufficiently to high temperature hot water for safe use in sanitary applications. The new Carrier heat pump achieves this and opens the way for large-capacity, commercial-scale renewable projects that weren't previously possible. This is obviously good for the environment and at the same time can potentially save building owners and end users on running costs.

"In addition, because the new heat pump is based on a compact all-in-one monobloc

design with a built-in hydronic module, installation is quick and easy, making life straightforward for the installer on site."

The heat pump is controlled via Carrier’s Touch Pilot Junior, which has an intuitive colour touchscreen and includes advanced communication technology, including web connectivity and alarm notification via email as standard.

For increased efficiency, the heat pumps can be equipped with one or two variablespeed pumps to save up to two thirds of pumping energy costs during part-load and stand-by periods.

Other options include soft start, for use on sites where electrical power is limited, a low noise version for use in applications such as healthcare and universities, and an external temperature sensor for use in weather compensation set-point control.

The AquaSnap 61WG is optimised for high temperature heating and hot water applications (above 50°C). For lower temperature applications, such as underfloor heating (around 35°C), the 30WG version is also Eurovent certified.

Living the green dream Aquarea T-Cap heat pumps play key role in family's eco-friendly self-build project.

Two Panasonic Aquarea T-Cap air to water heat pumps have helped to create an eco-friendly self-build dream home for a Cambridgeshire family.

Vincent and Jacqueline Haines wanted a reliable and renewable heating source to connect to two floors of underfloor heating for the 570sq ft Georgian-style property, in addition to a cost-effective supply of hot water for the kitchen and bathrooms.

It had always been a dream of trained architect Jacqueline to design and construct her own home and the project also incorporates triple glazing throughout and 43 solar photovoltaic panels.

The property is in a fairly remote location, and, with potential piping issues at the site, the family’s heating specialist, Roland Gurner from Eco Installer, investigated various renewable options and Smart controls allow for easy monitoring of energy usage

recommended two Panasonic Aquarea T-Cap heat pumps for the project, supplied by authorised Panasonic distributor Oceanair.

Vincent Haines said: “Panasonic is a well-known, reliable and efficient brand and proved excellent value for money. We opted to have smart remote controllers throughout the property, thus allowing us to monitor usage in each room. We have found the system to be reliable and energy efficient with the added benefit of a constant supply of free hot water.”

Ideal solution Roland Gurner said: “It was beneficial to be involved early on in this project, allowing us to look at the optimum space available for the units and advise on the best renewable solution. Two Panasonic Aquarea T-Caps were specified, partly because of the size of the property. It also means that when demand in the summer is lower and only the hot water is required, only one of the units is needed – of course this is also beneficial for the long-term impact and longevity of the system.”

Tony Holland from Oceanair said: “The Panasonic Aquarea T-Cap heat pump is very quiet compared to its competitors, aesthetically pleasing and highly energy efficient (COP of 5,08). The T-Cap stands for Total Capacity and can maintain the heating

capacity even at very low temperatures.

The T-Cap range is an ideal solution for this project as it can also be connected to a solar kit and smart controls in order to further increase efficiency and minimise the impact on the environment, which is precisely what the Haines family was looking for.”

The Aquarea T-Cap line-up can maintain the heat pump output capacity until -20°C outdoor temperature without the help of an electrical booster heater. The range is designed and produced by Panasonic and among the technologies listed on the International Energy Agency (IEA) Blue Map, whose goal is to reduce CO2 emissions to half the levels emitted in 2005, by the year 2050. www.aircon.panasonic.co.uk Two Panasonic Aquarea T-Cap heat pumps were used to heat and cool the property and supply hot water

Owner creates 'forever home' in rural setting following advice on renewable options.

A contemporary barn conversion in the North Norfolk countryside is benefitting from renewable heating thanks to Finn Geotherm.

Located near Swanton Novers National Nature Reserve, the four bedroom barn conversion was built by homeowner Michael Grand. A building supervisor by trade and with four other self-build projects already under his belt, Michael worked alongside Rutland Builders to transform the 1980s concrete beamed former grain store into a home with spectacular field views.

When it came to heating, the rural location of the barn gave Michael something to think about. He said: “The barn is off the gas grid so I looked at all the options. I’d had oil heating in my previous homes which was expensive to run and with this project to create my ‘forever home’, I wanted heating that was cheaper and self-sufficient. I did some research on heat pumps and my plumber CCHP also suggested the technology as an ideal choice for my project. I contacted Finn Geotherm and spoke to them initially about installing an air source unit.”

“The house is always warm – I installed a wood burning stove as part of the renovations but never actually need to light it!”

After completing a full site survey, Finn Geotherm recommended a ground source heat pump would be better suited to the property with its underfloor heating system. With land around the home in which to lay a collector loop, although it would be more expensive, a ground source heat pump would be more efficient and also generate a much greater income for Michael under the Domestic Renewable Heat Incentive.

Finn Geotherm specified and installed a Lämpöässä VM11 heat pump (a monoblock

unit – the same size as an American style fridge-freezer) with integrated 480 litre thermal store, capable of generating on demand and delivering up to 240 litres of hot water in one hit. A 600 metre ground array, laid in two 300 metre loops, was installed under the lawn. Michael has complemented his heat pump with the addition of solar panels on the barn roof.

He said: “I’m really pleased with my ground source heating. I am very happy with the recommendations made by Finn Geotherm to ensure the system fitted was the most suitable one for my home and my requirements. The installation went smoothly and the heat pump is working perfectly. The house is always warm – I installed a wood burning stove as part of the renovations but never actually need to light it!”

Simple steps to Uflexing your heat pump muscles The recently launched Uflex wet underfloor heating range is designed to partner with heat pumps.

Here Grant UK managing director Paul Wakefield guides us through an installation.

Grant UK’s wet underfloor heating range comprises of two systems – Uflex and Uflex MINI. Designed to partner effectively with renewable technologies, this underfloor heating solution complements and works alongside existing product ranges. Both systems are highly effective, easy to install and use the same manifolds. In this step by step we are looking at the Uflex MINI system.

Evenly distributing heat upwards into a room, the underfloor system maintains optimum room temperatures while also helping the heat source to work as efficiently as possible.

The Uflex MINI underfloor heating system has a number of features which make it an attractive option for both householders and installers. It has a very low profile, only raising the finished floor level by 15mm, which allows the underfloor heating installation to be completed without requiring significant changes to a room’s structure. Underfloor heating is also

August | September 2019

Grant UK.indd 62

unobtrusive, freeing up wall space and not impacting the position of furniture.

Utilising self-adhesive plastic panels, the Uflex MINI system can be installed by a single operative as the pipework loops simply clip into place, eliminating the need for staples. A real advantage is that this system does not require overboarding, unlike other retrofit systems, so the final floor finish can be laid directly on top of the dry screed.

Uflex MINI is therefore incredibly quick to install enabling the introduction of heat into the system within days, rather than weeks as is commonly the case with screeded systems.

The Uflex and Uflex MINI underfloor heating systems work incredibly well alongside the new Aerona³ R32 air source heat pump range. Consisting of four models in outputs ranging from 6kW up to 17kW, Grant’s latest heat pumps incorporate the more environmentally friendly R32 refrigerant

and, with their excellent SCOPs, are highly efficient. The 13kW and 17kW models also have the Quiet Mark which recognises and acknowledges their quiet operation, an important consideration for householders.

In addition, Grant UK can also provide design assistance which is really advantageous from an installer’s perspective. Available via the Professionals section on their website, Grant UK has an online design submissions form that customers can use to send in their plans and enquiries. The Renewables Team is then on hand to assist with producing outline system designs through to full drawings. Consequently, installers can turn to Grant UK for all their heating needs from design through to the product supply of heat pumps, cylinders and heat emitters through to MCS certification via the company’s G-CERT scheme. www.grantuk.com

POST-HARVEST CROP HYDRATION SYSTEMS

LINDAPTER LAUNCHES NEW CATALOGUE

Humidity Solutions offers the latest ultrasonic humidification technology to reduce dehydration suffered by crops whilst in cold storage. The natural, adiabatic process uses pure water and no chemicals to fill cold stores with a visible fog.

Rehydration maximises the pick weight, enhances quality and locks in the natural freshness.

Fixings specialist Lindapter has launched its new English (metric) catalogue with more than 100 updates including new products, more approvals and the latest technical data.

Additional benefits include lower energy costs as this process promotes more efficient cooling with less energy used due to removing field heat quickly. The produce will see an extended shelf life: crops can be stored for longer periods or when weather conditions are poor - otherwise known as strategic cropping.

This technology is gaining in popularity at a time when consumers are pushing for reduced plastic usage as crops can be stored ‘naked’, and longer shelf life helps fight against food wastage.

Our crop hydration systems can be retro fitted into existing cold stores or installed for new build.

www.humiditysolutions.co.uk

The Type CF2 clamp has been introduced into the catalogue to extend Lindapter's existing product range and meet market demand.

The new Type CF2 additions are High Slip Resistant Clamps designed to suit larger steel sections with thicker flanges. They are available in sizes M12, M16 and M20 with clamping ranges of 12-20mm, 15-25mm and 18-30mm respectively.

Another addition to the catalogue is the Type AMD which offers customers a wider choice of quality products within the Decking Fixing product range. The fixing has been developed to allow building services to be suspended from AMD60 and AMD80 decking profiles manufactured by Anglian Metal Deck Ltd. The new CE marked fixing creates genuine efficiencies for the contractor as it’s installed within seconds and is adjustable onsite without the requirement of specialist labour, expensive tools or power.

The catalogue contains information for structural engineers and other specifiers of steelwork connections, along with an enhanced layout for easier browsing.

GRANT UK UPDATES TECHBOX APP

HOT WATER UNIT TRANSFORMS VRF SYSTEM

Grant UK has updated its TechBox app for heating engineers. Changes include a new layout, new features and additional functionality.

Toshiba’s Super Heat Recovery Multi (SHRM-e) VRF system can now be used to produce hot water up to 82°C by adding a hot water module.

Grant UK launched TechBox almost five years ago, giving installers and heating engineers an electronic resource for all Grant product manuals, both current and archive. Users who download the updated app will now be able to select the content most relevant to them. The TechBox now invites users to select the product categories that they want to download.

Previously, content changes were made when the app itself underwent an update on the stores. Now, Grant UK will be able to manage document updates directly through the app so the latest manual changes will be live on the TechBox more quickly. When a manual update is made, users will be notified via a number icon in ‘Settings’.

They then simply need to navigate to ‘Manage’ and select ‘Update’ which will allow the TechBox to update all the changes within the product categories downloaded.

In addition, the TechBox has a new document search functionality and a ‘Favourites’ option. If there is a PDF download that an engineer refers to regularly, they can save it as a favourite which will allow them direct access to the file by clicking ‘Favourites’ in the app footer.

www.grantuk.com

The unit transforms Toshiba’s three-pipe VRF system into a highly efficient hot water generator suitable for use in hotels, gyms, restaurants, shops and offices. With a wide operating range from minus 25 to 40°C, the manufacturer says it can produce hot water year-round without impacting normal cooling and heating operation.

It uses a cascade heat exchanger to harness the output from SHRMe’s high performance heat pump, adding a second stage of compression to upgrade the energy to produce high temperature hot water via a refrigerant-to-water heat exchanger.

Toshiba adds that the energy costs for hot water production compared to a conventional electric immersion system are significantly cheaper. For example, heating 3000 litres of water from 15°C to 65°C using an electric system costs £23, whereas using the hot water module costs £6.62.

The high temperature hot water module is available in 5HP configuration, which is capable of providing 14kW of heating to generate hot water up to 82 degrees Celsius. Up to two modules can be combined per SHRMe system.
