Essential Information for the Air Conditioning and Refrigeration Industry

Working together for future of the industry

20

The need for our industry to work alongside education to develop its workforce of the future was highlighted at an excellent recent event organised by the Institute of Refrigeration’s Women in RACHP network.

The main aim of the gathering was to encourage more diversity in the workforce and the discussion broadened to cover many points which could have a positive impact across the engineering sector as a whole, regardless of gender.

The speakers were united in their belief that businesses need to engage with children at a younger (primary school) age and stressed the value of getting the message across to parents that engineering, and vocational training as a genuine alternative to university, can offer a rewarding career path.

Attracting talented young people into the industry is not easy but initiatives such as this can play a big part in opening up the lines of communication between business and education. A great effort from everyone involved.

BESPOKE TOSHIBA VRF FOR CROSSRAIL

A bespoke VRF air conditioning system has been developed to meet the unique demands of London’s Crossrail project.

A team made up of representatives from Toshiba Air Conditioning UK and Crossrail has provided the solution for contractor Laing O’Rourke. It will be used to provide a high quality temperature-controlled environment in ticket halls, station control centres and equipment rooms.

Key design challenges were meeting London Underground’s strict fire safety requirements, and integrating refrigerant leak detection and management systems to ensure the safety of workers and the public.

The London Underground fire-prevention code places strict limits on the use of plastics below ground. The team carried out a detailed evaluation of all components in Toshiba’s indoor units. It resulted in the drain pan being replaced with an all-metal version, and several other components – such as fans, motors, controls and insulation – being replaced with non-plastic alternatives.

The system is equipped with Toshiba’s new integrated LD2 refrigerant leak detection and management technology, which constantly monitors refrigerant charge in relation to performance. In the unlikely event of a leak, it sends an alarm signal and automatically isolates the site of the leak, preventing further loss.

The VRF condensing units connect to bespoke floor/ wall-mounted and ceiling-suspended indoor units. Toshiba is supplying around 30 of the specialist units to Laing O’Rourke, to be installed by contractors Conair UK and Skyline Air Conditioning.

Cold room distributor for trade

A new trade-only cold room distributor has been launched by Cold Store Rentals.

Refrigeration systems specialist Kevin Raworth has been appointed UK Sales Director of Cold Store Distribution, who will supply Italian-built Misa cold rooms to trade clients.

A pre-set range of 14 optimum sizes (chillers with and without floors and freezers) forms the basis of the offer, although other sizes are available. Cold Store Distribution says it is able to supply modular cold rooms within a week from its Hampshire warehouse.

Unlike Cold Store Rentals, which specialises in leasing long and medium-term rental and hire of cold rooms to the end user, Cold Store Distribution will sell to trade only, with a primary target market of refrigeration and catering equipment companies. They are the sole UK and Ireland based distributor of Misa cold rooms. www.coldstoredist.co.uk

PANASONIC CO2 UNIT ARRIVES IN UK

Panasonic’s 4kW/2HP CO2 condensing unit for commercial refrigeration is now available in the UK, aimed at small supermarkets, convenience stores and petrol stations.

Panasonic UK Marketing Manager Tony Nielsen said: “The main points to note with this product is its low carbon footprint, energy saving capacity, reliability and low refrigerant charge. Installation has also been made easy with its compact size and plug & play applications, ensuring a simple and low-cost install.”

TF Solutions are among the first UK distributors to stock the new units and Commercial Director Andy Reed said: “The new units offer a stable, natural and reliable solution that can help save on energy bills and are suitable for both freezing and refrigeration.” www.aircon.panasonic.eu

HITACHI OPENS

Glasgow office

Johnson Controls Hitachi Air Conditioning Europe has opened a Glasgow o�ce to strengthen direct sales support to its Scottish customers.

Martin Tanner, Area Sales Manager for Scotland, above, said: “The opening of the Glasgow office alongside our Johnson Controls colleagues will allow Hitachi to provide exceptional local coverage to both existing and potential customers, and will strengthen our brand position in Scotland. The decision to establish a presence in this region builds upon our strategic plans for continued growth and development across the UK.” Hitachi also has offices in Maidenhead and Dublin. The Glasgow office is at 4 Kilmartin Place, Tannochside Park, Uddingston, Glasgow, G71 5PH. www.hitachi-hvac.com

BEIJER REF IN JOINT VENTURE WITH MHI A joint venture has been formed between wholesale group Beijer Ref AB and Mitsubishi Heavy Industries to distribute MHI air conditioning and heat pump equipment in the UK and Ireland.

Beijer Ref is the majority owner of the newly-formed 3D Plus, which will operate separately. MHI products will continue to be sold through HRP and, from May, will also be available via the RW network.

Per Bertland, CEO of Beijer Ref AB, said: “The UK and Ireland markets are important to us and we continuously look at different ways of growing our market share with key partners. The technical expertise of MHI, and the distribution expertise of Beijer Ref, will be integrated to have a broader and more complete offering to the customers through this joint venture.

“It is our intention that 3D Plus will quickly become a similar size business to other Beijer Ref distribution channels in the UK. The MHI brand already has a strong market position which is a great platform for future growth. This joint venture further strengthens our

partnership and we look forward to seeing the progress of 3D Plus.”

John Billson Managing Director of Beijer Ref UK and Ireland, said: “I am delighted with this latest development. Partnering with MHI on an exclusive basis will strengthen HRP’s position whilst 3D Plus will complement it by opening new doors.”

Masayuki Fujinami, Managing Director of MHIAE, said: “MHIAE and Beijer Ref have had a successful relationship collaborating in the Scandinavian market for many years. Through the formation of this joint venture, we are happy to be moving beyond a traditional manufacturer and distributor relationship and to joining our two companies together in a way that will allow us to harness our respective expertise and experience jointly. MHIAE regards 3D Plus as a symbol of this integration and it will receive the full support of the MHI Group.”

Thermal storage to cut energy costs CIAT Group and subsidiary Cristopia Energy Systems have launched a thermal energy storage system in the UK and say it helps to reduce the load on chiller and electrical power requirements by between 30-70% for cooling production.

The system is said to reduce end users’ energy costs by shifting away from reliance on peak day-time power by harnessing offpeak electricity at night. It reduces the load on the chiller by smoothing-out peaks in the daily load profile, in the process also reducing chiller maintenance costs and the size of the combined refrigerant charge on a site.

Cristopia systems can be used for both air conditioning in buildings and industrial process applications. Air conditioning systems are traditionally designed to satisfy needs on the hottest days of the year, while industrial refrigeration systems often supply cooling energy

for short high-consumption periods, corresponding to production cycles.

David Dunn, Managing Director of Toshiba Air Conditioning and CIAT in the UK, said: “In the age of ever-rising refrigerant costs, and increasingly stringent legal requirements around F-Gas, we believe opportunities to reduce refrigerant charge will be highly attractive to end users with significant cooling loads. With better regulated cooling production and delivery across the daily cycle, there is the added bonus of reduced noise as a result of smoothing out peak chiller operation.”

The system, which will also be available from Toshiba Air Conditioning in the UK, is present in more than 3000 installations around the world, where it is transferring a combined 6 million kWh of electricity from peak to off-peak periods, saving more than 500MW of electricity.

CAREER DEVELOPMENT FOR WOMEN IN THE INDUSTRY The IOR Women in RACHP Network is hosting a career development day at Fujitsu Air Conditioning on 22 June to celebrate Women in Engineering Day 2018 (which falls on a Saturday this year) and build on the success of its recent careers breakfast.

The event at Fujitsu’s Elstree HQ in June will follow the format of last year’s day at Cool Concerns, with a practical element where delegates can gain hands-on experience of working with RACHP equipment and get a better understanding of the engineering principles involved.

Key industry and education figures debated the challenges of achieving more diversity and, specifically, attracting more women into the industry at the careers breakfast organised by network chair Samantha Buckell and sponsored by hosts Bitzer UK, Fujitsu and the ACR Journal.

Respected engineer and co-owner of training company Cool Concerns Jane Gartshore spoke of the need for a change of culture, adding: “Our industry is diverse, but only in a masculine way.’’

She said that 99% of the engineers who attended training courses at Cool Concern s were male. Jane also stressed the importance of assuring young people that it was “OK not to go to university” and consider alternative routes into the workplace.

Great success

Lisa Pogson, Managing Director of Airmaster Air Conditioning, outlined the value of building relationships and trust and described how the company regularly visits local primary schools to engage pupils at as early an age as possible. She said: “It is sometimes too late by the time they get to secondary school, so we go into the primary school, show them the CAD drawings of a project we are working on and say ‘cool, isn’t it’.

Colleague Ian Fisher, Business Development Manager at Airmaster, came into the industry as an apprentice and says he kept his job by making himself indispensable to senior engineers. As a STEM ambassador, he often talks about having the right attitude. He also pointed

Dawn Kennedy, Jane Gartshore, Shelley Bowdery, Lisa Pogson, Ian Fisher, Chris Holmwood of Shenley Brook End School and Samantha Buckell

out that most of the engineers he knew had come into the industry through family and friends, rather that more traditional routes.

Shelley Bowdery, former Head of Maths and Science at St Joseph’s College in Reading, echoed Ian’s thoughts about getting young people engaged at an early age. She also said businesses should dripfeed information about opportunities in the industry and show how relevant science is to our everyday lives. Shelley added: “This is a golden opportunity for apprenticeships because many students are looking for something that won’t leave them with a £60,000 debt.’’

Dawn Kennedy moved into teaching physics four years ago after an engineering career which saw her in

senior roles at BAE Systems, Royal Mail International and Amazon. She is now Physics Lead, KS3 Learning Leader and STEM+ Co-ordinator at Hazeley Academy in Milton Keynes and says she made the move because she wanted to “put something back.” She highlighted the disparity between the numbers of male and female students choosing science options, particularly physics, at A-level.

Samantha Buckell said: “The day definitely met all expectations and I look forward to seeing what actions do come from it. I am extremely grateful to our presenters, who not only brought great knowledge but also made the opportunity to share experience and opinions among those in attendance very easy. It was a great success.’’

Bookings for the event at Fujitsu can be made through the IOR website at https://ior.org.uk/events/ Anyone interested in getting involved in the Women in RACHP Network can join the LinkedIn group or contact Samantha Buckell samantha.buckell@bitzeruk.com

WHY I LOVE TRAINING Ben Bartle-Ross looks at the value of keeping your skills up to date.

W

e are in what I see as a really exciting period for the HVAC sector at the moment, with new technologies, refrigerants and new equipment regularly coming onto the market – and at the same time, legislation is focusing attention on the equipment that engineers are installing as never before.

Regulations such as F-Gas are forcing change throughout the industry as can be witnessed by the 700% price increase in R410A refrigerant in a very short space of time.

This is leading to new systems using R32 refrigerant as the industry grapples with the need to use refrigerants that reduce the global warming potential (GWP) of systems overall.

Manufacturers such as ourselves are also entering new sectors in a big way, with a whole new range of chillers, IT cooling and air handling unit products that could be seen as competing with our traditional air conditioning and VRF products.

And that’s even before you factor in the continuing growth of heat pump technology taken from the aircon industry to provide heating to the domestic and commercial sectors.

So just what is a traditional air conditioning engineer to make of all this change?

Things don’t stand still for long

And how can you keep up to speed and ensure you gain the skills necessary to capitalise on what are significant opportunities for growth?

Ultimately, that is why I am a trainer because I love the fact that things simply do not stand still for very long in our industry.

That certainly keeps me on my toes, getting to grips with the latest product changes. It also means that I can spend time working out the best ways to arm the engineers who come through my training rooms to make sure that they can grasp the opportunities for their business from this change.

The thing to ask yourself

For me, the big question for any traditional air conditioning engineer is what additional skills they need to be learning or acquiring to help ensure they have the right tools in their arsenal to enable them to keep healthy and growing as a business.

One thing is certain though is that things are not standing still, so neither should you, otherwise you risk being left behind and missing out on the opportunities that other products and markets can offer.

So whether that is getting to grips with new refrigerants; gaining a better understanding of the water-side of HVAC and moving into new areas; increased knowledge on how to size a heat pump for heating; or just understanding the implications of current legislation such as MEES, ErP, F-Gas, or the RHI scheme, you need to decide what is important for your business.

The next step is then looking around at where you can acquire the skills necessary to future-protect yourself and your business.

I’m sure I can find you a relevant training session at one of our regional centres…

NEW HIGH CAPACITY SLIMLINE UNITS ‘A FANTASTIC ADDITION’

F

ujitsu has extended its Airstage J-IIIL Series VRF range with the arrival of two new 40kW and 45kW outdoor units.

This increases the number of outdoor models with side discharge fans in the J-Series of standalone heat pumps to 14, with capacities from 12.1kW to 45kW. The two new side discharge units (AJY126LELAH and AJY144LELAH) have a slim profile with a low height, ensuring they are extremely compact. As a result, each product has a much smaller footprint than current models with the same output capacities.

Compared to Fujitsu’s existing Airstage V-Series 14/16HP products, for example, the new J-IIIL units are 285mm smaller in terms of depth, meaning they take up 45% less space. They are also 23% lighter in weight.

Despite the smaller footprint, Fujitsu says the optimum heat exchanger structure allows up to 40 indoor wall mounts, mini ducts, floor mounts or cassettes to be connected to one external unit. This is the maximum number of indoor units possible for a system of this capacity and Fujitsu says

The Airstage J-IIIL Series is now available in capacities up to 45kW

the new VRF systems are ideal for small room applications, including hotels and officeblocks.

levels during operation. This enables units to be installed without the need for specialist soundproofing. Plus, Fujitsu’s advanced refrigerant control technology allows for a maximum refrigerant piping length of 400m, opening up further system design and installation possibilities.

Colin Goode, Product Manager at Fujitsu, said: “These new VRF units are a fantastic addition to the Airstage J-IIIL range and we’re proud to be one of the first UK manufacturers to offer this configuration of outdoor unit in this capacity size. Their slim design offers designers greater flexibility, including the option to fit them beneath windows without blocking any views, while multiple units can also be fitted in a smaller area.

Plus, ductable fans (up to 60Pa) also allow them to be installed in ventilated plant rooms, further adding to their flexibility for city centre applications, where outside space may not be available or permitted.”

For more information about Fujitsu, visit http://www.fujitsu-general.com/uk/

The J-IIIL models also feature a large, 570mm propeller fan and a 15-120rps scroll compressor, ensuring low noise

Using R410A refrigerant, the full Hitachi Sigma VRF range benefits from a new high efficiency DC inverter compressor for precise control by 0.1Hz increments which achieves a 4.6% increase in seasonal efficiency over previous models.

Combined with a new fan design, bellmouth fan housing and sigma-shape heat exchanger, the Set Free Sigma VRF range achieves improved efficiency even at low or partial load in cooling operation, with performances increased to achieve SEER up to 8.33 and SCOP up to 5.06.

Gboyega Obafemi said: “Perfect for the UK market, the new Hitachi Sigma VRF models deliver increased installation flexibility and, when combined with our changeover boxes and valves, enables both 2-pipe heat pump and 3-pipe heat recovery from a single unit for buildings where heating and cooling are required simultaneously.”

Hitachi’s new Set Free Sigma VRF range is available from Hitachi Direct Sales in the UK and Ireland and its approved distribution network.

What’s next for JCH

The factory in Barcelona, currently celebrating its 25th anniversary, will be the location of a new training centre, opening in September.

New and extended line-up

Available from 5 to 24HP in a single unit module and up to 96HP with combinations, the outdoor unit casing has been completely redesigned and offers a total of seven new capacity models – 18, 20, 22 and 24HP (standard) and 14,16 and 18HP (high efficiency). This extended line-up achieves higher power combinations from fewer units, requiring fewer connections and delivering improved installation flexibility – meeting the needs of specifiers, installers and end users.

THE NEXT GENERATION

M

itsubishi Electric says its new City Multi YNW models are the cheapest to install and operate and offer the lowest CO2 emissions of any current VRF system.

The company adds that improvements mean the range delivers ultra-quiet noise levels, increased performance and a reduced footprint.

Jordan Jeewood, City Multi product specialist at Mitsubishi, said: “The new City Multi YNW models deliver the lowest installation costs, the lowest running costs and the lowest CO2 emissions currently available in a VRF system.’’

The YNW outdoor units include a new 4-sided heat exchanger to maximise the space available for plant by reducing the area required for air conditioning modules.

Improved compressor and fan design also help to reduce sound power, making the YNW one of the quietest VRF systems on the market.

Jeewood adds: “We’ve looked at how to improve the system in almost every area and this means improvements across the board. In the case of our most popular 34kW model for example we see a 19% increase in seasonal efficiency, making compliance with energy legislation easier to achieve.”

Air source VRF is a popular choice for commercial buildings in the UK and growing urban populations have led to an increase in multi-use buildings with office, retail and leisure spaces in close proximity to both residential and hotel accommodation. Noise and plant space has become a key issue and Mitsubishi says the City Multi YNW has been designed to address these challenges whilst meeting energy efficiency legislation.

The City Multi YNW also offers incremental capacity steps which give increased flexibility in noise output control.

This flexibility is further enhanced with multiple external static pressure settings, extended up to 80Pa which will help with long or narrow ducting requirements.

Jeewood said “We have increased the amount of cooling capacity that can be delivered per square metre of plant by 28% thanks to the advanced wrap around heat exchanger. This means less space is needed for outdoor modules and greater flexibility in where they can be located.”

Easier maintenance

These new models are available in capacities from 22kW to 150kW to offer some of the highest levels of efficiency coupled with smaller footprints, reduced noise levels and increased design options.

City Multi’s heat recovery two-pipe option also allows for phased installation, meaning that the cooling and heating system can be installed around a project build, with individual sections commissioned as required.

Up to 50 indoor units are connectable to the larger outdoor unit models and a complete new range of Branch Controller (BC) boxes is now available with reduction in height, a removable drain pan and a reduced refrigerant charge.

A completely new piping layout for the Branch Controllers (BC) boxes also increases the options for designers and installers and can help reduce installation time and make maintenance regimes easier.

SHELF EDGE TECHNOLOGY

AND THE CABINET DOORS DEBATE

Bob Hurley FInstR, Director of Retail Engineering Solutions, looks at these two visible ways of driving cabinet efficiency and highlights the challenges and benefits involved.

cold air, so shoppers may linger in the not so cold aisle longer! So far, so good.

The issue is that if 80+% (indicative) of people are ‘door happy’ (let’s not confuse matters at this stage by stating which door type), then up to 20% may not be ‘door happy’. No retailer in a saturated marketplace, with competitors often within three miles, wants to risk upsetting up to 20% of its customers, or see them browse less. And some retailers will have a bias against doors even with CQT data.

D

uring my career, I have been involved with trialling many door options – sliding, hinged and the fatally �awed universal door; hinged for replenishment, sliding for customers. These solutions were subject to myriad and diverse opinions which makes the decision-making process di�cult and few of these were based on fact. Often, the retailer in an end user business felt the door was a barrier; the engineer felt it was an energy saver. And then there is the decision of which door ‘type’ is best!

In wanting to listen to customers we carried out a number of Customer Question Time (CQT) sessions, across countries, to gather the most important opinions – those of our customers. Our customers often felt that, just as with their personal domestic refrigerators, the door kept the product colder and was also good at keeping the shopping aisle warmer. This is a key benefit of any door or shelf edge technology, if energy is reduced you must be losing less

Fact one:

If legislators determined that doors must be fitted, then everyone is in the same position and effectively the issue goes away – or at least everyone is in the same place.

Some would argue that doors remain a barrier to ‘impulsive shopping’ and in these times, where individuals are encouraged to look at dietary details and manage their intake, this could lead to doors being held open for longer while a nutritional label is read, compounding their inconvenience…

As legislation supporting the universal fitting of doors has still not arrived, and doors have had some impact but have by no means been universally adopted in the UK (mainland Europe is more pro-door in part, as stores are often planned differently, so a hinged door will not impact upon aisle space negatively), there has been an opportunity for shelf edge technology (I mention here an interest in shelf edge technology manufacturers, as I have been engaged in some work with them).

The concept originated, I believe, many years ago when Bonnet (EPTA), showed at Euroshop a new idea, with the ticket strip being spaced forward of the shelf edge, creating an extra support to the cabinet air

curtain, helping reduce turbulence.

They demonstrated this with an oil injected mist and a laser. This was an interesting first step but never evolved until, in the last few years, the involvement of significant CFD (Computational Fluid Dynamics) capability from the motor racing industry, resulted in a significant step forward. Patents were registered and many of the UK retailers began trialling shelf edge technology, as none had made the move to 100% doors, instead favouring certain store formats.

Even on selected formats, the wise retailer understands that a high turnover cabinet is best left without doors, especially hinged doors, as the resultant air change (think bellows) may not be good for product temperature, and the shopping aisle in peak periods will be congested. Although there are, of course, benefits during closed and low trade periods.

Alternatively, the sliding door may result in less air change but could be considered obstructive to the module of food either side and, most importantly, the nature of a sliding door introduces more mechanical parts and the potential for increased maintenance costs.

Fact two:

The simplest door is hinged.

Already used in significant quantities across the world as a chilled door, frozen food door and half glass door.

APRIL/MAY 2018

20-21_Refrigeration - Bob Hurley.indd 20

27/03/2018 10:20

The sliding door has a place, especially if the engineering can be improved to make it more reliable, but this is yet to be proven. The sliding/hinged door is not worthy of further discussion, it is simply too complex for a retail environment and prone to malfunction. All door solutions need great LED lighting, which does of course nibble away at the energy savings achieved. Does shelf edge technology require additional lighting? From the instore trials I have seen, it doesn’t but this can change by cabinet manufacturer and needs to be reviewed.

The sliding door was initially developed to address the issue of tight aisles and the desire not to block customer flow.

In a narrow aisle, I would argue that someone shopping a cabinet has a similar obstacle, whether the door is sliding or hinged. The key question I ask here and one I have never received a considered response to is, removing assumption and bias, when will a study with the use of CCTV and actual shopping behaviours be used to inform decision making? All too often, it is a decision based without fact or supporting data, which decides which door is used. Much of this results in a reluctance to install doors across formats in the UK, where store planning can easily result in doors facing doors and the assumption of congestion.

This is why shelf edge technology is gaining some momentum with a number of retailers adopting it across some formats, or at least trialling the solutions. The resultant savings seen in test laboratories at 25deg c/60% RH do make for some significant savings; the writer having seen up to -37%. This is of course not in store conditions, so this frequently reduces the savings obtained,

21

R E F R I G E R AT I O N

to nearer -15%. More testing and large roll outs will confirm a more consistent consensus on what can be saved at 20deg c/50 % RH. More consistent temperature banding and performance than open fronted cabinets has also been seen with this technology, though a challenge is ensuring good replenishment routines in store, so that the product is not placed on the shelf edge technology as a de facto shelf extension. A product riser can help counter this issue, but the purpose of the product riser needs to be in conjunction with staff training on correct merchandising. It is also important for shelf edge technology to be kept as narrow as possible. The deeper it is, the more prone to damage, use as a shelf extension, and less attractive to retail designers, it will become.

Fact three and summary:

deliver the best possible benefit given the challenges of a given location and trading pattern, on-going maintenance and, most importantly, deliver a positive shopping experience for the customer. After all, we want the shopping experience to remain positive or the world of .com will further accelerate.

All this is similar to the plant discussion our industry faces. No one natural solution is best. The solution selected needs to best address the challenges of the application, its ambient and local skill set, in delivering, servicing and maintaining it.

The future:

Shelf edge technology and/or doors can save energy and can improve temperature bands and product temperature. But they need to be selected appropriately and to

No-one has a crystal ball but the increase in CFD use in refrigeration cabinets (with more innovation to come?) is surely just the start. When was ducting in the HVAC industry, for instance, subject to a next step forward? I may not be aware of all that is being developed but the potential for managing air better is surely nearer the start than the finishing line. Which is an optimistic place to be in.

How F1 technology is helping to drive supermarket savings

Sainsbury’s is using technology partly developed by the Williams Formula One team to reduce electricity consumption across its stores.

The retailer says the Aerofoil technology is helping it to cut electricity usage by up to 15% – as well as making the aisles more comfortable for shoppers by reducing the amount of cold air that escapes.

Williams Advanced Engineering, the technology and engineering business of the Williams F1 Group, worked with UK start-up Aerofoil Energy to develop the device using its expertise in aero and thermodynamics. It says the programme across all 1,400 of the retailer’s UK outlets will result in energy reductions of 44m kWh a year.

Sainsbury’s believes the overall saving could be as much as 15 per cent.

The device, inspired by the rear wing on a Williams F1 car, has shown significant reductions in energy consumption and was trialled in 50 stores. Sainsbury’s is installing the Aerofoils as part of a retrofit programme, and all new fridges will be fitted with the technology as standard.

UNBELIEVABLE! Engineer Keith Simmons left humbled by IOR accolade after 45 years in the industry.

‘HE IS LOVED BY OUR CUSTOMERS AND RESPECTED ACROSS ALL AREAS OF THE BUSINESS. THAT IS SOMETHING QUITE SPECIAL’ FLOWRITE CEO TOD HARRISON

E

ven though a week had passed since he collected the Service Engineer Section Lifetime Achievement Award at the 118th Institute of Refrigeration Dinner in London, Keith Simmons was still coming to terms with it all.

Keith, who is Technical Supervisor at Maidstone-based Flowrite Services, has spent 45 years in the industry and said: “It’s unbelievable… I just didn’t think I would ever get something like this. I never really gave it a thought.

“Even when I was nominated and had the interview, I thought that would be the last I heard about it, so when I was told I had won, I was humbled.

“I just get on with my job, really, but I’d like to think I have been committed to every company I’ve worked for, so perhaps that has something to do with it.’’

Keith was nominated by Flowrite Business Manager Colin Meadowcroft, who said: “Nothing is too much trouble for Keith. He often spends his own time working to bring along the less experienced engineers. He has a great knowledge of the industry, an exemplary attitude, and is a major asset to our engineering team. He never complains, and always helps out when needed.

London That is something quite special.

“We have gone through something of a cultural change in the last couple of years and have four key aims: visibility, ownership, trust and excellence. Keith is really supportive of everything we are trying to do and it’s great to see him recognised in this way.’’

After a brief spell as a film technician, Keith took his first job in the industry with Total Refrigeration and spent 11 years there, largely on cold rooms and cabinets, before moving to Stanleys, where he worked for 12 years and built up extensive knowledge of retail refrigeration.

A chance meeting with the MD of Total saw him return for another 7-year stint, handling contracts for Iceland and Esso, and he joined Flowrite almost 17 years ago.

Keith, 67, said: “It’s a nice feeling that the company thought I had a chance of winning this award. There have been a lot of very positive changes at Flowrite over the last 18 months and it’s a good place to be.

“Of course retirement has crossed my mind but I still feel as though I’ve got a bit to offer and as long as I feel fit enough, I’d like to carry on.’’

J&E Hall Gold Medal winner Eckhard Groll with Steve Gill and J&E Hall Managing Director Mark Roberts

Kenneth Lightfoot Medal winner Rob Lamb with Steve Gill

Professor Eckhard Groll was recognised as the 2018 winner of the J&E Hall Gold Medal for his work on compressor evolution. In more than 23 years at Purdue University, Indiana, USA, he has led teams whose work has benefited heating, ventilation, air conditioning and refrigeration industries across the globe, with unique contributions in the field of positive displacement compressor analysis.

Together with colleagues and graduate students, he has developed detailed and comprehensive simulation models of hermetic PD compressors, including scroll, rolling piston, reciprocating, linear, rotating spool, bowtie and S-RAM using different working fluids including HFCs, HFOs and natural refrigerants.

Professor Groll said: “I am very excited to receive this award, particularly considering the history of J&E Hall and the fact that the company was the inventor of the first CO2 compressor. I have worked in this area throughout my academic career at Purdue. The link is absolutely fascinating for me.”

One of the first comprehensive models Professor Groll and his team developed focused on predicting the performance of horizontal hermetic scroll compressors. The research enabled Panasonic to successfully develop a new version of their scroll compressor, the e-scroll, in the early 2000s.

He is currently working on achieving isothermal compression processes in linear and twin screw compressors by 3D printing internal cooling loops inside the critical compression parts to achieve hotspot cooling.

Professor Groll said: “I know many of the accomplished people who have won this award over the past decade or so and I feel I am being elevated into an elite group. I love this job. I am also educating students and this has always been at the forefront of everything I do.

Rob Lamb of Star Refrigeration won the Kenneth Lightfoot Medal for the best evening paper for Refrigerant choices for small scale industrial refrigeration.

The paper looks at how small refrigeration systems are often overlooked when discussing the future of refrigerants but play an important role in providing cooling to a wide variety of markets. The paper looks to provide an insight into the refrigerant options available with the aim of aiding end users and contractors in selecting the optimum refrigerant for their application. The paper is free for IOR members and is available for download from the IOR website.

FREEZING OUT WASTED ENERGY

The food sector remains a major consumer of energy. In fact, the resources needed to cultivate, process, package and bring food to the table of consumers accounts for an astounding 18% of the total UK energy use. Shaun Evers, Managing Director of Stonegate Instruments, explains how cutting-edge technologies are helping to reduce energy use and make equipment run more efficiently.

A

ccording to the latest research, refrigeration costs account for up to half of some organisations’ energy bills. And while upgrading to the very latest, energye�cient equipment may be beyond the reach of many businesses, a combination of simple steps and technologically advanced devices can help give huge electricity bills the cold shoulder.

With sustainability at the forefront of decision-makers’ minds, those tasked with identifying savings are looking to do so alongside reducing carbon emissions, as a result of increasingly stringent industry regulations.

Generally speaking, the harder a system has to work to stay at the right temperature, the more energy it will use.

Therefore, minimising the heat load is an essential part of energy management.

Over-filling a refrigerator will also increase energy use, as without sufficient room for air to circulate, the cabinet will have to use up to 20% more energy.

Users should ensure that neither the grilles at the front of a unit nor the coolers in cold rooms should be blocked as this not only results in increased energy use but can compromise temperatures at which food is stored.

Keeping a unit at precisely the right temperature also plays a key role in reducing energy consumption; in fact, the Carbon Trust estimates that overcooling by just 1°C can lead to a potential rise in annual heating bills by up to 8%.

One simple yet effective way to ensure equipment is operating at the correct

temperature is to install a thermometer that is easily visible from a distance. This does not necessarily need to be huge; in fact, the latest designs are both compact yet easy to read thanks to a brightly lit display.

Cause and effect

Shaun Evers of Stonegate

According to figures from WRAP, the Waste and Resources Action Programme, food and drink production accounts for around 20% of the UK’s C02 emissions. This includes the energy needed to produce the 10 million tonnes of food that goes to waste each year; while consumers are being encouraged to shop wisely to reduce this, the supply chain also has a part to play in ensuring food is not spoiled before it reaches the supermarket shelves.

Produce needs to be stored and transported at exactly the right temperature to avoid it being spoiled and thrown away, therefore refrigerated equipment all needs to be functioning correctly.

Energy inefficiencies in refrigeration can occur for a number of reasons, including equipment failure and doors being left ajar. However, gas leaks are the foremost contributor to energy loss in modern cold stores.

Many refrigerated stores were built more than 20 years ago, so it is no surprise that some of these older systems are somewhat prone to gas leaks. The Carbon Trust estimates that such leaks reduce the efficiency of refrigerated units by around 11%, which in turn impacts on the amount of food wasted.

APRIL/MAY 2018

Stonegate.indd 24

27/03/2018 10:22

R E F R I G E R AT I O N

Spotting and rectifying gas leaks not only reduces energy usage but helps protect both the environment and employees. Workers who have been exposed to refrigerant gases can suffer irritation to the eyes, throat and skin, frostbite or chemical burns, and in severe cases, have sustained lung and brain damage.

Left unrepaired, even a minor leak can become costly in terms of both energy used and the associated costs – after three months it could account for an extra 10kW in use, or around £1,400 extra on an energy bill. Current EU legislation requires all appliances with 300kg or more of refrigerants to be fitted with a leak detector, while cold stores with between 3kg and 30kg must be tested annually and those with 30kg or more need to be tested twice a year.

While technology cannot as yet pinpoint when a leak is imminent, it can alert workers immediately as soon as one does happen. The latest generation of gas detectors are equipped with audio and visual alarms and can detect a large range of toxic and non-toxic gases.

Alarms such as those manufactured by Stonegate Instruments can detect CFCs, HCFCs and HFCs, accommodating up to 24 remote refrigerant sensors connected to a compact central monitor. In the event of a gas leak, these activate an alarm and LED lights, which pinpoint where the leak occurred.

PRODUCE NEEDS TO BE STORED AND TRANSPORTED AT EXACTLY THE RIGHT TEMPERATURE TO AVOID IT BEING SPOILED AND THROWN AWAY”

While gas leaks are the biggest contributor to energy loss in refrigerated systems, leaving doors open can also contribute.

What may seem like a small error can prove to be costly, as a system must work harder to stay cool when a door is left open, incurring higher energy costs.

Installing a warning system can prevent doors being left open for long periods of time, reducing energy usage as well as preventing food becoming spoiled. www.stonegate-instruments.com

OPENING THE DOOR TO ENERGY SAVINGS A new innovation designed as an alternative to the night door for food retailers has been welcomed by a number of supermarkets and other key customers.

T

hermal insulation specialists Seymour Manufacturing International (SMI) says its latest innovation can offer significant savings to major retailers.

The Green-Door (which is actually blue) is available for both freezers and chillers and has been designed as a more lightweight and user-friendly replacement for the heavy sliding night door, with the potential to save a considerable amount of energy and physical effort for users.

After years of research and nearly a decade of testing at sites across England, Scotland and Northern Ireland, the company says it is now opening the door to savings through the use of SMI’s Tempro, claimed to be the world’s thinnest and most thermally-efficient material of its kind.

Andrew Watson, store manager at ASDA Glasshoughton, Castleford, said: “The Green-Door has brought lots of benefits since installing it in place of the old night door.

“It is much lighter to use – reducing the risk of injury - much easier to clean, and saves us energy and money too.

“I would have no hesitation in recommending it, particularly in an area where there is a great deal of footfall.”

SMI Chairman Brian Seymour said: “Cheap flip-flap doors have been used in chillers for several years, despite having relatively short lifespans, high maintenance costs and breakage.

Little maintenance

“We researched the real needs of the food industry and targeted economic performance, being user friendly, and longevity.

“With Green-Door, the aim was to create a quality door that would require little maintenance, was easy to use and saved significant amounts of energy, and carbon.”

SMI has been running low-key trials at a number of supermarkets to test the

product’s performance under realistic and gruelling conditions – and the company says it is delighted with the positive feedback.

Brian Seymour added: “Green-Door makes the much-hated supermarket night-door redundant in chillers and freezers, saving capital, maintenance costs, nuisance value and labour.

The advantages and savings are enormous.

“It is easy to use, it saves expensive energy and carbon, it reduces maintenance costs and the need to fit the hated timewasting, labour-intensive, costly night-door.

“In fact, when return on investment is considered, the Green-Door could pay for itself on day one, depending upon what size and cost you pay for a night-door.

The saving on maintenance and labour can just be treated as a bonus.”

Dave Perry, SMI’s Divisional Sales Manager, said: “Put simply, our Green-Door is a ‘fit and forget’ item which allows easy access for staff, a constant closed-door solution, and is virtually maintenance-free.

“With a lifespan of many years, it is incredibly cost-efficient in comparison with a standard sliding chiller door.

Our first Green-Door set up at a test site in Taunton back in 2009 is still going strong.”

SMI is based on the Stafford Park industrial estate in Telford, Shropshire, and has been saving energy and money for some of the world’s biggest and best-known businesses since the 1980s.

The company’s client list includes retailers Waitrose, Morrisons, ASDA, Sainsbury’s, Marks & Spencer, The Co-operative, and Lidl.

It also works with the NHS and the Ministry of Defence and has become a leading thermal insulation supplier for the protection of food, chemicals, agricultural and home delivery products.

GREEN POINT GEARING UP

TO MEET GROWING DEMAND

G

reen Point UK has invested in new compressor testing facilities and expanded remanufacturing capacity as part of its strategic growth plan.

The new facility enables Green Point UK, Bitzer’s compressor remanufacturing arm, to carry out full run tests on remanufactured screw compressors inhouse, rather than transporting them to Green Point’s base in France. As a result, turnaround time on remanufactured compressors has been reduced from around three weeks to three days.

It enables the company to run-test open drive screw compressors at Milton Keynes, with full control and oil separation.

The testing station includes a new control panel and associated switch gear.

Will Pribyl, Green Point UK’s General Manager, said: “Turnaround times can be important on some projects, as, despite our comprehensive stock, it is not possible to stock all models that might be required. The new rapid turnaround time gives customers an edge, enabling them to deliver for their own clients and get systems up and running quickly.’’

The investment includes the addition of further production capacity, to meet growing demand for Green Point’s high quality remanufactured compressors. It will be accompanied with new technical and office support staff over the coming year.

Alongside, stocking of fully remanufactured screw compressors of popular models is being increased, providing a same-day or next-day delivery service on live projects.

The latest investment follows Green Point’s introduction of new valueadded services to enhance its support for customers. These include turnkey logistics for managing compressor removal and replacement, offsite preventive maintenance, and specialist onsite commissioning support.

Logistics support covers a full compressor “lift and shift” service by

a dedicated team, which manages all aspects of removal and replacement with as-new remanufactured exchange compressor/s. The specialist team can manage all aspects of complex compressor handling operations, from restrictedaccess plant rooms in deep basements to the top of multi-storey buildings.

Green Point’s preventive offsite maintenance service covers scheduled proactive replacement of hard-running compressors in critical applications, such as process cooling and food storage, to pre-empt problems or potential breakdown.

Will Pribyl added: “Following Green Point’s launch in the UK in 2014, we are now gearing up to meet growing demand for remanufactured compressors. With the addition of value-added services, increased production capacity and the ability to fully test systems in-house, we now provide a comprehensive service that is highly flexible and responsive, all underpinned by BITZER’s high quality approach to engineering that ensures reliability and efficiency.”

Engineers from industrial refrigeration specialist Pennine Environmental Services completed a one-day training course in the latest screw compressor technology at Green Point UK. Three engineers, two experienced and one trainee, attended the course in Milton Keynes, with sessions led by Mick Nicholson, Green Point’s senior compressor remanufacturing technician.

The engineers were tasked with disassembling a returned semi-hermetic screw compressor and assessing the reasons for failure. The project was completed by reassembling an open-type unit to full operational status.

Mark Bailey-Stansfield, Pennine Environmental Services’ Technical Operations Manager, said: “Our engineers found the day extremely worthwhile, and the hands-on experience particularly valuable. It gave the opportunity to strip a screw compressor down to the component level, examine and report on the findings, and then rebuild a unit from scratch.

“This is something you simply don’t have the opportunity to do in the field with the expert support of Green Point at every stage of the process.”

COMPLIANCE WITH NEW R

NEVER COME AT THE E

Martyn Cooper, Commercial Manager at the Federation of Environmental Trade Associations (FETA), highlights the dangers of charging a system with a refrigerant that it was not originally designed to use.

T

he current F-Gas regulation, introduced in 2015, is now having a major impact on the refrigeration, air conditioning and heat pump markets. Organisations such as FETA have put much e�ort into getting over the issues surrounding the regulation, such as the publication of the PURR report in September 2015, subsequently updated in January 2018 to re�ect market developments over the last two years.

An A2L refrigerants working group has been formed to co-ordinate FETA’s activities in this area and a guidance note entitled An introduction to A2L refrigerants and their use in Refrigeration, Air Conditioning and Heat Pump applications has also been released. [Both publications available as free downloads from www.feta.co.uk] Compliance with new regulations should never come at the expense of safety. It was therefore of great concern for us to learn of some instances of R410A (classified as A1; non-flammable) being completely removed from an air conditioning system, and the system simply being recharged with R32 (classified as A2L; low flammability).

A2L gases in retrofits

R410A has been used in many types of air conditioning and heat pump systems in Japan, Europe and the United States since the 1990s, but with its Global Warming Potential (GWP) of 2088, manufacturers are now leading the way in moving towards more environmentally friendly products that

make use of R32 as a replacement for R410A. Like R410A, R32 is an HFC, but with a much lower GWP of 675, and is classified as A2L (low flammability).

It is vital to underline here the fact that refrigerant manufacturers have clearly stated that A2L refrigerants must only be used in new systems designed specifically to take into account their flammability characteristics. They are not suitable for

IT IS CRUCIAL THAT MANUFACTURERS, INSTALLERS AND END USERS WORK TOGETHER AND HELP EACH OTHER TO GET A GRIP ON THEIR RESPECTIVE RESPONSIBILITIES” retrofit without a full risk assessment being undertaken, any necessary modifications being made, and the whole process being recorded in the system’s logbook. A system that was originally designed for R410A will not have taken into account the safety factors required when using an A2L refrigerant and could create a significant safety hazard. Systems specifically designed for use with R32 will, for example, have different pressure switch regimes, altered inverter profiles, and specially designed heat exchangers.

Due to their lower flammability, A2L refrigerants are intended for use in equipment specifically designed for these products and should always be used in accordance with the relevant national and international standards. If in doubt, the manufacturer of the existing system should always be consulted regarding which refrigerants can be used in an air conditioning retrofit.

EN378

The European refrigerant safety standard EN378 specifies the charge size allowable for different applications of flammable gases which ensures they cannot form a flammable atmosphere and hence are safe in use.

Charging an existing system with R32 could leave the system non-compliant with this standard, leading to the possibility of forming a potentially dangerous environment in a leakage situation.

Potential damage and risk of liability

If you replace the refrigerant in a system with another refrigerant, for which that system was not designed, then you are increasing the likelihood of causing damage. R32 has a higher compressor discharge temperature than R410A, and will increase wear on the compressor, reducing its life significantly. Installers are therefore leaving themselves open to potentially huge personal cost by retrofitting A2L gases into systems that weren’t designed for their use because the liability will rest with them if the replacement refrigerant

W REGULATIONS SHOULD

E EXPENSE OF SAFETY’ causes any problems or damage to the existing system.

Most air conditioner and heat pump manufacturers will offer a warranty on their products to cover repairs and replacements when required. Using a refrigerant not specified for the system will render any relevant warranty invalid.

It would also mean that the system would no longer be compliant with its original CE marking or the Pressure Equipment Directive specifications, and could have insurance implications.

Positive action

New products and technologies are being developed as quickly as possible to make air conditioning systems more environmentally friendly and we as an industry must take positive action to ensure the necessary communication, training and skills are in place to implement these systems correctly.

All technicians carrying out work on stationary RACHP systems must hold an F Gas handling certificate. This requirement applies both to in house staff and to personnel employed by external contractors.

FETA and ACRIB have been closely involved in the development of Trailblazer apprenticeship schemes for the industry, and much work has gone into incorporating the changes anticipated by the advent of the regulation. A new training course dealing with all types of flammable refrigerants has also been developed.

As stated earlier, the F-Gas regulation is going to have a significant impact on the RACHP industry, and it is crucial that manufacturers, installers and end users work together and help each other to get a grip on their respective responsibilities.

Failure to do so will inevitably lead to serious consequences.

THE HEAT IN THE F-GAS REFRIGERANT MARKETS R ecently, the Carbon Trust worked with the Kigali Cooling Efficiency Programme, the International Institute of Refrigeration and ASHREA to produce a KCEP service brief. The brief outlined the scale of global emissions due to refrigeration technology and the potential to save perhaps 20% of these emissions by undertaking simple, low cost or no cost measures.

In 2016 Total Global GHG Emissions was 53.4 GtCO2-e and of these between 3.8 and 4.1 GtCO2-e (7-8%) were caused by the approximately 3 billion pieces of cooling equipment is use (e.g. fridges, air conditioning, mobile air conditioning).

Breaking down the refrigeration emissions further, 1.5 GtCO2-e were direct emissions from the release of refrigerant gas and 2.6 GtCO2-e were indirect emissions of electricity use. If left uncontrolled, cooling related emissions could easily double by 2050. Cooling related emissions were probably about 435 MtCO2-e in Europe and were 34MtCO2-e in the UK (7.2% UK emissions). Of the UK’s emissions 12.6MtCO2-e are due to refrigerant emissions subject to control through the F-Gas regulation.

Across Europe the F-Gas regulation is focused on substantially reducing these emissions. The second and most substantial phase down step in the F-Gas regulation occurred on 1 January 2018.

A 37% reduction compared to the 2015 baseline of the 183 MTCO2-e is, when taking sales of new pre-installed charge equipment into account, actually a 44% reduction. Before looking forward to what might happen in 2018, let us step back and see what happened in the recent past.

Market reaction to F-Gas regulation

It is now very clear to all in the refrigeration market that the F-Gas regulation directly affected the price and supply of refrigerant product across

By Paul Huggins, Associate Director, Programmes, at the Carbon Trust.

But price is not the only way in which the refrigeration market is reacting – it is transforming. The recent report by the European Environment Agency on Fluorinated Greenhouse Gases (2017) makes interesting reading on the dynamics of the F-Gas markets: ₀ 2014 was an exceptional year for placement of F-Gases on to the market, with an approximately 80 MtCO2-e one off increase in refrigerant product placement on to the market when compared with other years. Multiple explanations have been used to explain this jump, such as better F-Gas reporting or industry stockpiling.

Europe in 2017. Those products with the largest GHG emission impact are being most impacted (e.g. R134A, R404A).

Perhaps not surprisingly in hindsight, the F-Gas market began to react strongly to an impending reduction in the supply of these gasses in first quarter of 2017.

Since then the price of a wide number of refrigerants, but particularly R404A have risen by more than 400% when compared with early 2017 pricing, or 600% when compared with early 2016 pricing.

This very strong 2015 price signal should encourage clients to switch to lower GWP refrigerants and suppliers to ensure they’ve a strong stock of alternative lower GWP refrigerants which clients can buy.

PRICE IS NOT THE ONLY WAY THE MARKET IS REACTING - IT IS TRANSFORMING”

₀ What is now clear is that some of this additional supply may have been used to recharge refrigerant equipment sooner than planned. This point is made as both the level of reclaimed refrigerant and destroyed refrigerant have changed notably since 2014.

Between 2014 and 2016 the level of destroyed F-Gases increased from 1MtCO2-e to ~7.5MtCO2-e in 2014, 11MtCO2-e in 2015 before falling back to ~5MtCO2-e in 2016. Over the same time period reclaimed refrigerant gas increased from 1.8MtCO2-e, to 2.4 MtCO2-e then 4.1MtCO2-e. ₀ The market didn’t consume the available F-Gas market quotas in 2015 or 2016, falling short by 8% in 2015 and 4% in 2016, but still much higher than the 2018 quota. ₀ Since 2017, OEMs have had to purchase an authorisation to use the F-Gas quota from a quota holder before they can place their refrigeration, air conditioning and heat pump (RACHP) equipment on to the market. Presently there is a stockpile of such authorisations equivalent to

₀ Since 2014, the bulk composition of the basket of refrigerant products supplied to the market has changed. Prior to 2014 the average GWP of refrigerant gas sold in Europe was 2,468 (7 year average). In 2014 average GWP had reduced by 7%, by 11% in 2015 and by 13% in 2016 to be 2,141. All appreciably higher than the typical annual 2% background variation in average GWP of refrigerant.

What does this all mean when looking ahead?

It is very clear that prices for refrigerant product will continue to increase due to the impact of the F-Gas regulation. The highest price increases in 2017 were in the refrigerants with the highest GWP impacts. This is likely to remain the case in 2018. At the same time, it is quite likely that the price of other refrigerants with lower GWPs will also rise, particularly if demand for the lower GWP exceeds short-term supply.

emissions related to cooling.

The Kigali Amendment will come into effect on 1 January 2019, one year to the day after the latest F-Gas regulation phase step down. Conceptually the Kigali Amendment is similar to the F-Gas regulation. The global HFC phase down under the Montreal Protocol Kigali Amendment introduces limits to the consumption of HFCs, starting in 2019.

In 2016, HFC consumption in the EU was the lowest since reporting started in 2007 and was already 14% below the first limit for the EU under the Montreal Protocol Kigali Amendment. Europe is likely to be well prepared to meet the requirements of the Kigali Amendment, however most other nations will not and this could impact the future supply of F-Gases to the EU market.

Assuming actual demand for refrigerant gases across Europe is not appreciably different in 2018 than it was in 2017, then the 44% reduction in available quota (assuming OEMs buy allocations) means the average GWP of the basket of refrigerants sold across Europe will have to be 1,200 – a GWP reduction of nearly 1,000. There will have to be an exceptional difference in the refrigerant choices of clients to achieve this average GWP. Refrigerant manufactures and suppliers have done their homework and let us hope that they are ready to work with their customers to identify the right lower GWP product for them.

Percent

22% of the maximum available HFC amount for 2017. This stockpile gives OEMs flexibility to sell new products for, according to the European Commission, the next 18 months.

The commission also argues that this in turn frees up the F-Gas quota to be used for refrigerant supply. This assumes that further authorisations are not sold to OEMs and there is no evidence that this might happen. If further allocations are sold then the F-Gas market will tighten further – something you might ague is the purpose of the F-gas regulations!

THE F-GAS HONEYMOON P

ITâ&#x20AC;&#x2122;S TIME TO MAKE THIS M Allan Harper, Managing Director of IDS Climalife UK, talks to the ACR Journal about his market predictions.

M

any IDS Climalife customers will remember me saying last year that the honeymoon period with F-Gas is over and now we have to make the marriage work! We have certainly seen some changes.

The price of refrigerants rose steeply during the course of 2017 with R404A bearing the brunt, reaching a 900% increase in less than 12 months. The good news is that we have seen a big move from the industry to the much lower GWP refrigerants and as I write we have not seen any problems with any of our customers using the HFO blends R448A and R449A as replacement products for R404A. During the course of 2017 I think all of us faced some tough challenges in dealing with the implications of the quota and my feeling is that 2017 gave us a good lesson on how we could expect to manage the major cut in quota at the start of this year.

All quota holders will have to reduce the CO2 tons equivalent placed on the market by 32%. This is a major reduction and is

basically designed so that end users stop using high GWP refrigerants such as R404A or R507A. Although some might see this as excessive, there are plenty of replacement options with much lower GWP values which in theory will ensure that F-Gas will be successful and that there will not be any major shortages in the supply of refrigerant.

Another transition

In the UK we always tend to be a little bit ahead of the curve and it has been great to see that we have seen many announcements from the major retailers on their plans to move to the low GWP refrigerants. This unfortunately is not the case in some parts of Europe which seem to be much slower in making this transition but I am happy to report that all of our

N PERIOD IS OVER…

S MARRIAGE WORK Climalife offices across Europe are working really hard to help customers to meet the F-Gas requirements and challenges.

Over the coming months we will have a big push on helping our customers and the wider market to understand more about A2L refrigerants. As many readers will be aware, A2L refrigerants are mildly flammable but as such they come with even lower GWP values than those containing an HFO blend (non-flammable).

Some might say that the industry is still coming to terms with the new products such as R448A & R449A but we have to remember we started talking about these products over two years ago. We now need to start another transition of working with

OVER THE COMING MONTHS WE WILL HAVE A BIG PUSH ON HELPING OUR CUSTOMERS UNDERSTAND MORE ABOUT A2L REFRIGERANTS”

these new mildly flammable refrigerants which again will ensure that the demands of F-Gas are met. Remember that we started with 182 million CO2 tonnes equivalent in 2015 and in 2030 that figure needs to be no more than 33 million! This can only be done by choosing the lowest possible GWP refrigerant according to system and charge size.

We have a huge opportunity this year to really drive down the use of higher GWP refrigerants. As someone that’s always been passionate about the planet and the environment I can proudly say that I’m leading a company which is helping to contribute to a better and safer environment.

F-GAS FAQS -

ARE YOU READY

The phase-down of HFCs, driven by the EU’s F-Gas legislation, is well underway, with 2018 being the first of two significant dates for those affected. Here, Robert Franklin, Sales Director, Refrigeration and Air Conditioning at Wolseley, outlines the 2018 and 2020 legislative milestones and explores some key questions the market is asking as we start to feel the effect of the first significant supply cut.

T

he European Union F-Gas regulations have been cited as one of the most complex and signi�cant changes to the refrigeration and air conditioning market in recent times. Price hikes and a strategic phase-down of HFC use have made many businesses slow to respond, but this is now changing.

What is the F-Gas regulation?

The 2014 EU F-Gas regulation (517/2014) aims to better control the production, import, export and use of fluorinated greenhouse gases across Europe.

Refrigeration contractors and end users must ensure that existing systems are compliant with the F-Gas regulation and that the rules are taken into account when selecting new equipment.

The regulation has set strict targets to lower the use of the most impactful fluorinated greenhouse gases, or F-Gases. These gases have the highest levels of Global Warming Potential (GWP) and are therefore most damaging to the environment. They include the widely used R404A, which will be banned from use in commercial applications by 2020 – the second of the two significant dates.

The UK signed the Montreal Protocol on ozone depleting substances alongside more than around 200 other countries. In 2016 the Kigali Amendment to the Montreal Protocol created new international controls on HFCs and introduced an international phase-down in HFC production and consumption. Although Brexit will adjust how the legislation is scribed in UK law, it is reasonable to assume that the phase down and overall objectives will remainuntouched.

In other words, Brexit will not change this legislation and businesses who remain non-compliant will be heavily penalised.

To drive the phase-down of F-Gases, a quota system has been introduced to control sales of gases like R404A across the EU market. This quota system affects all HFC producers, importers and exporters, and is based on control of bulk Hydrofluorocarbon (HFC) production and distribution. There are additional controls in place for the import of precharged products.

Will anything happen this year?

Whilst 2020 marks the ultimate ban of virgin refrigerants over 2500 Gwp in systems containing more than 40t equivalent CO2, 2018 is a key date for the available CO2 quota. Combined with precharged equipment, the CO2 quota will reduce by 44%, effectively decreasing the physical amount of refrigerant available to the market by half. However, the good news is that low GWP alternatives to the old refrigerants are readily available and will negate the physical reduction.

Businesses need to be proactive in adopting these lower GWP alternatives to avoid being hit by depletion in supply and price escalation of the older refrigerants.

For some businesses this is hugely impactful, with many teams being retrained on safe working practices for the recovering and charging of flammable refrigerants and how to deal with a sensitive customer conversation.

Other considerations include the need for additional space onboard vehicles, which now need to transport a larger variety of refrigerants.

You may need to consider purchasing new tools and gauges too, especially in relation to R32, as well as introducing

37

I’ve noticed a hike in price, why?

Robert Franklin of Wolseley issues a reminder that 2018 is a key date in the HFC phase-down

a new labelling system and reporting software to cut down on electronic F-Gas log books and reports.

Is it just the EU restricting the use of HFC refrigerants?

Will Brexit change things?

Reducing carbon footprint is a primary objective of The European Union and the F-Gas regulation is a key part of this. It is important to remember though that the HFC phase-down in the UK and Europe is part of a global shift change with the US, Japan and other countries making similar demands.

When the F-Gas legislation was announced in July 2014, many companies stock piled the now regulated gas in order to keep prices low and avoid supply issues. This stockpiling sheltered the bottom of the supply chain from the change, because everything was seemingly ‘normal’ with no real price change or sense of urgency.

This is now no longer the case, and things are suddenly changing dramatically, with stockpiles dwindling and the cost of conventional gas choices like R404A sky-rocketing since the end of 2017.

DON’T PANIC YES, YOU DO NEED TO SWITCH BUT R404A IS STILL AVAILABLE

A-Gas Commercial Director Enzo D’Alessio offers reassurance on the way forward.

L

et me begin by reassuring you that R404A is still available for installers and end users. The recent pressure on high GWP refrigerants, such as R404A, has been immense due to this year’s phasedowns under the F-Gas Regulations. R404A, with a GWP of just under 4000, has been particularly hard hit and this year’s 37% cut in the quota – 44% if you include pre-charged requirement – for the production of virgin gases has taken its toll.

A GAS HAS INVESTED HEAVILY IN ITS RECLAMATION AND RECOVERY FACILITIES”

The good news is that last year’s aggressive price hikes for high GWP refrigerants appear to have ended and the market has to some extent now stabilised. The supply of virgin high GWP refrigerants has decreased and refrigerant reclamation is playing a key role in this shift of emphasis. Under the quota system, the availability of recovered gases is having a significant effect on supplies to the market as reclaimed refrigerant is quota exempt.

Retrofit refrigerants

A-Gas has invested heavily in its reclamation and recovery facilities over the years and this has been reflected by the recent addition of a new high capacity gas separator in Portbury. In the reclamation process we use distillation technology to separate refrigerants of different boiling points. Once a gas leaves the separator it is sampled, certified to the meet the AHRI 700 standard and re-supplied to the market outside of the quota system. This source of supply is reassuring for users who are yet to make the switch to a low GWP refrigerant.

I am pleased to report that a steady stream of R404A continues to make its way back to A-Gas as installers and end users are making the switch to lower GWP gases. That said, market behaviour APRIL/MAY 2018

around reclaiming product appears to have changed, with users now keeping hold of recovered refrigerant that they would have otherwise returned. There are strict guidelines governing this and the reclaimed gas can only be used on the same premises and only once it has gone through a basic cleaning process.

I am pleased to report that we are selling less R404A than we did a year ago.

The message about the importance of switching to lower GWP refrigerants has

39

been taken on board by many users and this has been reflected in the market place. An achievement we as an industry should be proud of.

What will happen to the use and price of R404A is anyone’s guess. Yes, you do need to switch, but if you haven’t done so yet we are confident that your service and maintenance needs will continue to be covered for the foreseeable future.

For those looking to change there are several suitable retrofit refrigerants for R404A available but Opteon XP40 (R449A) and Solstice N40 (R448A) are the ones that can really make a difference. They are currently the lowest GWP replacements (around 1400) and are closely matched to R404A in terms of refrigeration capacity.

What’s more, the gap between the cost of R404A and its low GWP alternatives is narrowing in the industry.

Further rises

Another refrigerant feeling the pressure as a result of the phasedowns is R410A which is widely used in air conditioning systems.

There have been significant cuts in the quota for virgin R410A and this has had an effect on availability – especially as the refrigerant used in pre-charged equipment is to be taken from the quota allowance.

I suspect that there may be further prices rises ahead for R410A. The good news is that as far as the mildlyflammable A2L replacements like R32 are concerned they are being seen as a viable alternative for new equipment, although use in retrofitting has been slower as A2Ls are far from being drop-ins and a different approach is needed by the contractor.

As an industry we are working hard to meet the F-Gas challenge. We are moving away from high GWP refrigerants and opting for lower GWP alternatives. We are making good progress in our use of A2Ls and these refrigerants have the potential to make a real impact on the industry and ease the pressure on contractors as the stepdowns get steeper.

New refrigerants will continue to emerge to offer solutions for the installer and the end euser. It is no doubt a time of change and it is important that we stay open minded to what may develop as we make the switch from high GWP gases to their low GWP alternatives.

HEAT SHIELD FROM JAVAC: Join the brazing revolution

Heat damaged o-ring gaskets? Burnt or charred components? No water available for a wet rag? Keeping things cool on site can be a problem for engineers, says Scott Davies, UK Sales Director for JAVAC UK.

U

sing a wet rag to stop heat travelling through copper when brazing, soldering and welding is the traditional method of protecting heat sensitive areas around a welding site.

If a wet rag can even be found on site, the method presents issues for the engineer. A wet rag can be awkward to position and can fall off the pipe. It can dry out from the inside; attaching itself to the pipe meaning it needs to be doused.

Additionally, despite the heat blocking intentions of using a wet rag, heat does transfer to components when welding.

A wet rag can create warpage and damage, as quenching the weld may harden it and make the surrounding metal more prone to cracking.

Components can heat up despite using a wet rag, whereas using a heat blocking putty like JAVAC Heat Shield protects the pipe and keeps it cooler for longer.

Proven to block conductive heat transfer, Heat Shield putty protects pipes, surfaces and sensitive areas from heat damage. Simple to use and reusable up to 40 times, apply the putty to the area that needs protecting; braze, solder or weld, allow to cool, peel off, remould and reuse.

No rag, no worries!

Time-saving, non-toxic and with a no-mess formula, Heat Shield is the perfect tool for combating conductive heat transference.

Technical specification ₀ Non-flammable ₀ Insoluble in water ₀ Direct heat - blocks direct heat up to 2000°F ₀ Use up to 40 times ₀ Indicator DYE - special dye fades over time to indicate when replacement is needed ₀ Non-toxic ₀ Use with Map/ Pro, Oxy/Acetylene, Mig, Tig, Arc and Propane torches

HEAT PUMPS RENEWABLE ENERGY

I

n a world with an everincreasing focus on renewable technologies, the role of the heat pump is destined to increase as products continue to develop and knowledge and awareness grows.

Many businesses and homeowners are taking a keen interest in using green

technologies in offices and homes and that trend seems certain to continue.

Heat pumps extract heat from a range of sources, enabling them to supply more energy than they consume.

The heat can be drawn from the air, warm

exhaust air, water sources such as rivers, the ground or even waste water. And unlike other systems, heat pumps can also be used for cooling.

Read about some of the companies who are working hard to raise the profile of these technologies on the following pages…

LG….a growing force in heating and cooling technology

The LG brand is well known across the world and in the UK its association with consumer products – particularly TV’s and smart phones – have seen its relatively new air conditioning and energy solutions business gaining ground quickly and becoming a significant player in the marketplace. In particular, its reputation for the latest and most effective controls has seen its products in demand, particularly with those keen to maximise the connectivity of systems and the ability to integrate heating or air conditioning systems with building management systems and the like.

Its sales in the air conditioning and the heating sectors, with its high quality air to water air source heat pumps and its increasingly sophisticated variable refrigerant flow (VRF) solutions, has seen it carve a niche in these highly competitive marketplaces, and one that is growing year on year.

LG operates out of its impressive headquarters building just inside what is left of the historic Brooklands banked motor racing circuit, in Weybridge in leafy Surrey. As well as being the headquarters building for LG in the UK its also home to a mighty impressive training academy, allowing those taking courses there to have ‘hands on’ experience with all the LG equipment available. The training centre was opened in 2015 and has trained more than 4,000 people since, on equipment that includes the Therma V ranges of air to water heat pumps which have been immensely popular, its Multi V VRF range of equipment, the engineered solutions on offer from LG and the wide range of user interfaces from simple controls to the most advanced options that can interface with the most complex of building controls systems on commercial properties.

The latest heating product range introduced and promoted to the UK housebuilding sector is LG’s Therma V range of air to water heat pumps: “Selecting the right air to water heat pump is about carefully thinking through the lifestyle requirements of the home in which it will be installed,” says Andrew Slater Engineering Manager for LG UK and Nordic. “LG’s LATS Therma V is a selection program with quick and easy results. By specifying a number of parameters, LATS Therma V shows annual energy costs compared to conventional heating systems and a CO2 annual amount, monthly energy amount and costs and total amount of Therma energy in kWh.” In modern homes, with several bathrooms it’s common to see heating demand halved and hot water demand tripled – so high temperature air source heat pumps are ideal in this scenario – perfect for many refurbishment projects and spot on for new build properties.

Multi V 5™ - LG Electronics Variable Refrigerant Flow (VRF) solution was launched in the UK in late 2016, equipped with a host of technological advancements. These include a ‘Dual Sensing Control’ system, which monitors both temperature and humidity levels, reacting to both sensible and latent heat loads.

The new Multi V 5 features LG’s own 5th generation ultimate

inverter compressor and a larger system capacity offering, along with improved seasonal efficiencies, making Multi V 5 the ultimate climate control solution.

An industry first - the LG Multi V S™ Heat Recovery - boasts superior energy efficiency, as evidenced by a 3.90 energy efficiency ratio (EER) in cooling operation and a 4.39 coefficient of performance (COP) in heating operation, whilst it is capable of achieving an ESEER value of 8.05 and a heat recovery potential COP of 9.57, in nominal operating conditions. Designed specifically for small to medium-sized spaces, this compact and lightweight model offers simultaneous heating and cooling as well as the production of domestic hot water, with considerable installation flexibility and efficiencies.

The Multi V S Heat Recovery offers a host of unique LG technological developments, including LG’s own 5th generation compressor equipped with a High Sided Shell (HSS) and a new Polyetheretheketone (PEEK) bearing which allows an all inverter system compressor to operate between 10Hz – 165Hz, increasing partial efficiencies, extending capacity, and increasing reliability. Both these systems – the Multi V5 and Multi VS Heat Recovery can connect to LG Hydro kits for the production of hot water and have been installed in high end residential properties as well as commercial applications.

More recently, LG has launched a new range of air-cooled, inverter scroll chillers into the UK market. The new heat pumps are available in from 70kW up to 211kW models offering superior performance and industry energy efficiency in ‘part-load’

conditions. The Inverter Scroll Chillers boast an impressive EER 2.65 / COP 3.2 / ESEER 4.79 . The new range is ideal for applications where space is an issue – these chillers are compact, with a foot print area of only 4.9m2, ideal where space is at a premium. The LG units feature low noise - at just 68dB(A) and can offer reduced noise levels at night, simply by adjusting the fan RPM.

Grant UK, Hopton House, Hopton Industrial Estate, Devizes, Wiltshire, SN10 2EU

Sustainable heating from Grant

Today’s society is becoming increasingly greener with its thinking. From Government legislation through to changes in individuals’ behaviour, sustainability is flowing through all aspects of day to day life. Heating is one sector which has embraced environmentally friendly concepts with cleaner, more efficient technologies at the forefront of product R&D. Here, Grant Engineering (UK) Ltd explores the important role that air source heat pumps could play in heating the homes of generations to come and why installers should be on board.

Grant Engineering was formed in Ireland in 1978. Over the course of the past forty years, the Grant brand has established itself as a market leader in the off-gas heating sector with its Vortex oil-fired boilers being the favoured choice for many engineers. The Company’s founder, Steven Grant, has always strived to develop and manufacture innovative heating solutions and, over the years, Grant Engineering has often been the pioneer, bringing new concepts to the market first.

While the Grant brand is synonymous with oil-fired boilers, its presence in the renewables sector has continued to grow, a reflection of how the Company’s product portfolio has adapted to meet the demands of the marketplace.

Homeowners are more aware of the alternative ways to heat their properties, spending increasing amounts of time researching how they can incorporate greener technologies into their home. Interest in renewable energy continues to strengthen and, while some factors can limit the number of householders able to install green energy in their homes,

there can be no denying that renewables will have a place in the landscape for heating tomorrow’s homes. To meet this demand from consumers, installers and manufacturers need to embrace the opportunities that renewable energy can present to them.

In 2010, Grant launched its first air to water heat pumps and today, the Aerona3 range is their third generation of air source heat pumps. Consisting of three models which are available in outputs of 6kW, 10kW and 16kW, the Aerona3 inverter driven ASHP range has been designed with both the end-user and installer in mind.

Compact in size, Grant’s Aerona3 models incorporate a series of features which are included as standard. Every unit is supplied with a factory fitted HE pump, flexi hoses, condensate drain elbow, isolating valves and remote controller, features which help make the installation quicker and save time for installers onsite.

With its simplified electrics, the Aerona3 is straightforward to install and the positioning of its main components towards the front of the unit makes maintenance and servicing simple too.

In addition, the Aerona3 has high SCOP’s and is available with a guarantee of up to 7 years (subject to T&Cs), providing the consumer with added peace of mind.

To further aid the installer, Grant supplies an extensive range of ancillary products which complement the Aerona3. Heat pump packs, which consist of the heat pump unit and its key accessories, are now available from Grant which not only simplify the order process, but they deliver cost savings as well. Grant

also has a range of stainless steel cylinders which are specifically matched to the Aerona3 and, in Spring 2018, this cylinder range will be further expanding. The new products will include a 50ltr buffer, 30ltr volumiser, and six new cylinders. The new cylinders will all incorporate the buffer as a combined unit with three of the models available as pre-plumbed units. These ancillary products are designed to maximise the heat pump’s performance while also delivering added benefits to the end-user.

For testimonies on the Aerona3, the feedback received from developers, homeowners and installers alike serves to highlight the product’s features and benefits. In Ramsbury, Wiltshire, a development of four luxury properties is underway and, at each new build, a 6kW Aerona3 model is being installed. The first installation took place before Christmas and the comments from both the developer, Polgate Ltd, and the installing engineer highlight how easy it is to work with Grant’s air source heat pump.

Howard Porter, of Polgate Ltd, writes, “I am impressed by two of the unit’s key features – its small size and incredibly low noise levels. This combination makes the unit very unobtrusive, something which was essential for this build because aesthetics were important.” Meanwhile, IND Plumbing and Heating, the G1 installing engineers, comments, “It took myself and my colleague approximately a day and a half to complete our first Aerona³ installation - we found the install much quicker than previous heat pump installs.”

Furthermore, the Aerona3 is also award-winning. At this year’s ACR and Heat Pump Awards, the Aerona3 was selected as a Finalist in the category for Heat Pump of the Year 2018 in which the range was awarded Highly Commended. This HC Award ranked the Aerona3 as the highest placed air source heat pump product in the category, recognition of the product and its innovative technology.

Change can be a daunting concept but Grant has always aimed to support engineers, helping them to evolve in accordance with their ever-changing workplace and embrace the opportunities it presents. To complement their product offering, Grant UK has an award-winning Training Academy which delivers product specific and industry courses at their HQ in Devizes and at other satellite training centres throughout England, Scotland and Wales. Equipping heating engineers with the knowledge they need in order to work effectively in the field has always been a core principal for Grant UK. Installer interest in product training continues to remain strong with Grant UK welcoming hundreds of engineers through its doors each year attending sessions, such as the two-day ASHP training which is one of the Academy’s most popular courses.

Grant UK also offers a wide range of services designed to further help the engineer. In 2017, Grant UK launched the G-Cert Scheme through which Grant can

certify renewable installations for MCS accreditation on behalf of the installer. Through G-Cert, approved installers can work on a sub contract basis with Grant UK to deliver their customers an MCS compliant heating system, without the installing company needing to be MCS accredited themselves. This initiative has proved popular amongst installers and, in particular, has attracted the interest of engineers who have not previously worked extensively with renewables. G-Cert allows its members to access new customer bases, specifically householders wishing to claim RHI support, thus further increasing the range of benefits that installers can gain from today’s market.

Air source heat pumps should no longer be considered a minority in today’s market. They can meet the heating demands of domestic properties efficiently, reliably and sustainably which has made them an increasingly popular choice for homeowners. In response, installers need to equip themselves with the relevant expertise and partner with manufacturers who strive to deliver complete product packages designed to make installation and maintenance user-friendly. When it comes to green thinking, consider an air source heat pump. And when considering an air source heat pump, think Grant.

PUTTING WASTE WATER TO WORK

Russ Burton says heat pumps are the cornerstone of the SHARC technology

How a pioneering process is making the most of an inexhaustible resource to recover heat. David Todd reports.

S

HARC Energy Systems is aiming to use a breakthrough year in 2017 as a platform for growth across the UK and Europe for its unique heat recovery system.

The heat pump-based technology takes the natural warmth from waste water and transfers the heat to the clean side of the heating system via a heat exchange mechanism. The recovered heat is then amplified via heat pumps to generate the appropriate temperatures for use in buildings.

Although based in Newark, SHARC is enjoying significant success in Scotland, partly due to the renewables policy north of the border and a strong partnership with Scottish Water.

SHARC and Scottish Water Horizons recently won the Innovation Award at the Scottish Green Energy Awards for its project at Borders College, in Galashiels.

That came just weeks after the same project won the Best Newcomer Award at the Green Gown Awards, which celebrate sustainability initiatives in the university and college sector.

The partnership with Scottish Horizons was further strengthened ith the creation of a joint venture to expand and accelerate

APRIL/MAY 2018

of a number of key green energy projects which are currently in the advanced stages of planning.

Scottish Water Horizons will provide commercial funding for the projects, with SHARC Energy providing the design, build and operational expertise for the green energy installations.

The Scottish Government is supporting the schemes by providing 50% grant capital support through its LCITP (Low Carbon Infrastructure Transition Programme).

The joint venture has been set up to manage the installation and maintenance

The Borders College scheme intercepts waste water from the nearby town sewer line operated by Scottish Water. It supplies the campus with the majority of its annual heating and hot water demand, enabling it to save 150 tonnes of carbon per annum.

The heat produced is being sold to Borders College under a 20-year purchase agreement, producing savings in energy, costs and carbon emissions. The scheme is the first of its kind in the UK and the first time the technology has been integrated with the public sewerage system.

SHARC opened a Glasgow office in July last year and has several more projects

in the pipeline, with the Aqualibrium Leisure Centre in Campbeltown and Kelvingrove Art Gallery and Museum in Glasgow forming part of the Bandwidth Project supporting Scotland’s decarbonisation programme.

The leisure centre currently uses five 135kW gas boilers to generate space heating, pool heating and domestic hot water. SHARC says gas consumption from April 2014 – March 2015 was 1,516,204kWh with a peak demand of 632kW. The proposed solution will have a peak capacity of 800kW and will aim to supply 90 per cent of the leisure centre’s annual demand. An estimated carbon saving of 144 tonnes of CO2 per year is expected, increasing annually as the electricity grid decarbonises.

Support

At Kelvingrove, the building uses four gas boilers rated at 895kW each on a duty standby basis. The consumption over the same period was 1,720,587kWh with a peak demand of 1108kW. SHARC’s proposed SHARC solution will be a packaged plant room in the grounds of the museum, with a peak capacity

of 1,400 kW, and will aim to supply 100 per cent of the site’s annual demand, resulting in an estimated carbon saving of 175 tonnes of CO2 per year.

SHARC will also be working on two district heating schemes, at the Clyde Gateway regeneration area in Glasgow and a project for Stirling Council.

Chief Operating Officer Russ Burton said: “We have had great support in Scotland and while the English market may not have

embraced us in the same way, some of that is due to where our focus has been.

“But we are determined to grow in the rest of the UK and Europe and hopefully the success and recognition of our completed projects in Scotland will help us to do that.

“Heat pumps are our cornerstone technology so a lot of what happens in the future will come down to how heat pumps are viewed as an energy source.’’ www.sharcenergy.com

HOW IT WORKS SHARC’s system is built on capturing the wasted energy that comes from water being heated, used, then flushed down the drain.

It estimates that more than 330 billion litres of wastewater is discharged through the sewer systems of North America and the EU each day.

The technology, which was originally developed in Canada, uses a clog-proof sewage filtration system and heat exchange technology that conducts the heat from untreated waste water and then re-distributes it.

The average temperature of waste water leaving buildings is 21°C (77°F) and because waste water is an inexhaustible resource, SHARC says it can guarantee customer price and supply certainty.

The company provides a design, manufacture and installation service and says the system can be used for new build or retrofit on commercial and residential developments.

TEAM COOLAIR RAISES £80,000 IN CHARITY CYCLE CHALLENGE Clients, consultants and employees of Cannock-based air conditioning installer Coolair Equipment have raised more than £80,000 for a cancer charity by cycling 300 miles through South East Asia.

Coolair Regional Director Neil Gibbard led the 17-strong group on the six-day journey from Saigon in Vietnam to Angkor Wat in Cambodia in aid of Challenge Cancer UK. After 12 months of training on UK roads, Team Coolair faced cycling for up to eight hours a day along narrow paths and unmade cross-country tracks in crushing humidity and on one day high winds.

Neil, who led a similar charity ride two years ago, after which he was made a Corporate Ambassador for Challenge Cancer UK, organised the challenge with the support of his company’s supplier and business partner Mitsubishi Electric Living Environmental Systems.

Neil, who also raised the largest individual sum of £9,030 towards the £80,846 total, said: “The team were all new to such a challenge and included biking novices, but everyone exceeded their physical and mental expectations - and their fundraising targets. Our many supporters and sponsors were tremendous in their encouragement and generosity.”

Accompanied by a local guide and a support vehicle for their bags, the party of 16 men and one woman cycled around paddy fields and along temple-lined tracks in the lush Mekong Delta in Vietnam and then through the dry lands of ancient Cambodia.

Team Coolair celebrates at the finish line at Angkor Wat in Cambodia

Team Coolair comprised Martin Atkins (Skerritt Electrical), Rodney Clarke (Dodd Group), John Ensell (Mitsubishi Electric), Mark Garstang (Coolair), Neil Gibbard (Coolair), Scott Lydon (Clancy Consulting), David Massey (Core Group Projects), Paul Mawdsley (Coolair), Lee Moores (Coolair), Carl Morphew (BSE3d), Joseph Pavitt (Norman Disney & Young), Lee Rattenbury (Grummant Heating), Craig Scott (GDM Partnership), Simon Seaton-Smith (Couch Perry Wilkes), Ian Webster (Kosco Interiors), Laura Welsh (Coolair) and Carl Wood (AF Connell). www.challengecanceruk.org

STAR EARNS THANKS FROM

WHEELCHAIR CURLING SKIPPER Team GB’s wheelchair curling team captain paid tribute to the work of Star Refrigeration before �ying out to the Winter Paralympics in South Korea.

Alasdair Sinclair was a mechanical engineer with Mexichem and studied at the University of Manchester

MEXICHEM SCHOLARSHIP

IN MEMORY OF FORMER COLLEAGUE

Refrigerant manufacturer Mexichem has launched a scholarship to support mechanical engineering students at the University of Manchester.

The Alasdair Sinclair scholarship, organised in memory of a Mexichem colleague who passed away, is awarded to a student with an interest in the chemicals manufacturing sector.

Mexichem Site Manager Tipu Salahuddin said: “Alasdair was a popular mechanical engineering manager who worked at our Runcorn site for 27 years. We were all shocked and saddened by his unexpected death in December 2015 and wanted to do something positive and long-lasting in his memory.

“We have worked with Alasdair’s wife, Marie, to develop this scholarship in his honour. The scholarship will provide financial assistance to deserving students at Alasdair’s alma mater, the University of Manchester.

Every year, one first year student will be chosen to receive the scholarship, which they will continue to receive each year of their four-year course. In addition to receiving £2,250 a year, the student will be eligible for a four-week placement with Mexichem in the summer following their first and fourth year. www.mexichemfluor.com/

The team has been training at the first National Curling Academy in Stirling and Star played a part in constructing the new curling rink as well, as the rink at Braehead Arena where bronze medallist Aileen Neilson trained for the Sochi 2014 games.

She said: “It is good to train and practice on different ice conditions but there is nothing better than training on ‘world class’ ice every day in preparation for playing at the major competitions.

I would like to thank Star Refrigeration for their continued support, and all the ice rinks we have used over the years.’’

Alan Walkinshaw of Star Refrigeration, who oversaw the project at the NCA, said: “We are thrilled to be developing top level training facilities to help UK athletes succeed in their chosen sports and reach their full potential.” www.star-ref.co.uk

Brymec backing brings water to Ugandan village A new well in Uganda is providing clean, fresh water for almost 1,000 people, thanks to funding from the charitable arm of building services provider Brymec.

The Kidoko well is the 635th to be drilled by charity Fields of Life and will supply 230 homes in the community. Kidoko is in the Tororo district of eastern Uganda where access to water is extremely limited.

Debbie Cameron, head of development and fundraising at Fields of Life, explained: “The nearest water source for this community was an open water source located 1.5km away which meant people from the village had to spend many hours walking long distances to collect water and would have to do this arduous journey numerous times throughout the day.

“This task usually fell to the women

and children resulting in children missing valuable school hours and women missing work. The water they were forced to collect was contaminated with many waterborne diseases which led to many in the village becoming severely ill and some loss of life.”

Joe Morris, marketing co-ordinator at Brymec, said: “We are delighted that we’ve been able to help people in desperate need of fresh water by funding the construction of the well at Kidoko. We hope it will be the first of many.

“The Brymec Foundation was established to formally structure how the company can fulfil one of the company’s core objectives - to help others.

The company actively promotes the foundation to support this cause.”

Swegon introduces latest addition to its GOLD Air Handling Unit The latest addition to the renowned Swegon GOLD air handling unit is the RX/HC – a fully integrated reverse cycle heat pump, developed to complement energy recovery from the unique thermal wheel and provide tempered fresh air to the ventilation system.

control system is self-learning to minimise defrost times and the number of defrost cycles.

Complete with the latest, digital inverter-controlled compressor technology the temperature control is delivered effortlessly and efficiently.

The package requires no other boiler, chiller or associated pipework, pumps and valves etc, so reducing the overall capital cost to a project and reducing risk by all requirements delivered in one smart package.

The overall efficient package, with a small footprint, creates the perfect solution for space saving versus traditional AHU and Condensing unit solutions and reduces the size of the refrigeration system and gases, vital in futureproofing against reduced availability of refrigerant gases.

The unit can be supplied with airflows up to 6.5 m3/s and provide up to 110kW of Cooling or up to 40 kW of Heating. The heat pump controller is combined with the GOLD AHU controls to provide seamless and optimised temperature control and all settings can be viewed or amended from one single HMI.

Developed in Sweden, the range has been fully tested to operate at temperatures down to minus 20°C so delivering a risk free solution. The unique defrost

SafeGarde your heating

Heat Shield from JAVAC

With more than 35 years’ experience in developing chemicals for ACR engineers, Advanced Engineering has turned its attention to heating, launching the threeproduct SafeGarde range.

The SafeGarde SG1 system cleaner and flusher is suitable for both newly installed and existing systems. It’s highly effective at removing debris, sludge and scale: in a typical domestic system it takes less than 60 minutes… with or without a powerflush machine.

The SafeGarde SG2 multi-metal corrosion inhibitor protects high-value components against limescale and corrosion, while the boiler-noise eliminating SG3 is safe to leave in a system for up to 14 days.

Using a wet rag to stop heat travelling when brazing, soldering and welding is the traditional method of protecting heat sensitive areas around a welding site. However, a wet rag can be awkward to position, can dry out and needs to be kept wet.

Proven to block conductive heat transfer, Heat Shield putty protects pipes, surfaces and sensitive areas from heat damage. Simple to use and reusable up to 40 times, apply the putty to the area that needs protecting; braze, solder or weld, allow to cool, peel off, remould and reuse.

No rag, no worries! Time saving, non-toxic and with a no-mess formula, Heat Shield is the perfect product for combating conductive heat transference.
