Aerofoil driving ahead

TF Solutions to sell Mitsubishi Electric TF Solutions is to sell Mitsubishi Electric equipment as part of the manufacturer’s Value Added Reseller (VAR) network. Andy Cherrill, managing director of TF Solutions, said: “Our mission is to work together for success and this principle has allowed us to remain a vital part of our customers’ successes over the past 18 years. We see this new association with Mitsubishi Electric as continuing on that path towards success, by allowing us to offer our customers the very best products available.’’ The news followed the announcement in December that Dean & Wood was switching brands from Mitsubishi Electric to Mitsubishi Heavy Industries.

LU-VE BUYS AL AIR Four new major customers have been announced for Aerofoil, the Formula One-inspired energy saving device for openfronted retail fridges from Aerofoil Energy. Following extensive trials, Marks & Spencer has seen proven energy savings, with the added benefit of a more comfortable in-store temperature. Results from existing client adoption of Aerofoils have shown that customers can save up to 30% on refrigeration energy costs through the retrofittable solution. Aerofoil is influenced by Formula One aerodynamics from Williams Advanced Engineering, part of the Williams Group that also includes the Formula One team, and is similar in appearance to the rear wing of a Formula One car. It uses aerodynamics to guide cold air down the fridge more efficiently, meaning substantially less cold air is lost from the chiller unit, resulting in lower energy use, fewer carbon emissions and warmer aisles in stores.

Transformative The M&S news was followed by the announcement that global travel retailer SSP Group is also to use the technology for its chilled food cabinets. SSP operates a portfolio of more than 500 international, national, and local brands in 33 countries around the world. Brands receiving Aerofoils include M&S, Café Ritazza, Millies Cookies, Starbucks, Camden Foods, Upper Crust and Spar Express. Ignite Energy conceived and implemented successful trials of Aerofoil in several SSP-operated stores in the UK, paving the way for the adoption of the technology more widely. Community retailer Scotmid Co-operative has also adopted the Aerofoil. The initiative is led by Impact Shopfitting, who specified the equipment after excellent feedback from store trials. Impact will manage the installation in Scotmid’s 186 convenience stores across Scotland and the North of England. And leading high street brand WHSmith has chosen to fit Aerofoils to its open-fronted refrigerators in more than 430 of its travel stores. ASDA and Sainsbury’s are among other retailers already using Aerofoil technology.

LU-VE has announced the purchase Alfa Laval’s commercial/ industrial air heat exchanger business and says the deal will put the company in the top three global operators in the sector. For the 12 months ending June 2018 Alfa Laval Air Heat Exchangers Division had revenues of €97.8 million. AL Air, based near Vicenza, owns brand including Fincoil and Helpman and manufactures in Italy, Finland and India. The deal will include the transfer of about 400 employees mainly based at the production sites.

KEEPING IT SIMPLE Electrician Karl Pettit has developed a cable tray mounting spacer which he says offers improved installation time of all sizes of light and medium duty cable tray for air conditioning and refrigeration contractors. TraySimple, which has taken four years to develop, is a plastic spacer that replaces the need to use either metal channel or stand-off brackets when installing cable tray onto walls and floors. The individual spacers clip into a perforation on the tray, which is placed in position then drilled and fixed through the tray and spacer, securing the cable tray to the wall. One spacer can be used to space the tray 21mm from the wall, to match up with tray already installed on shallow channel, or two spacers can be clipped together to provide a spacing of 41mm, to match up with deeper channels. Nottingham-based Karl said: “I am an electrician working in the air conditioning industry and the one job I did not look forward to was the cutting of metal channel and the installation of cable tray. It’s ideally suited to external and internal pipework risers and around the floor of a compound or the roof of a cold room.” TraySimple is available from Trentside Fixings in Nottingham, FCC in Mansfield (part of the ERF Electrical Group) and nationwide from Edmundson Electrical.

TOTAL SOLUTION WITH FLOWAY DX

Obituaries Ian Ramsay, a fellow of the IOR and veteran of the refrigeration industry, has passed away following a short illness. Ian was a refrigeration consultant and managing director at refrigeration design software specialist White Rose Software. He had spent more than 50 years in the industry and will be greatly missed. Allan Maguire passed away in early December following a short stay in hospital. He retired from Glasgow Kelvin College in August after a long career as a lecturer in Building Engineering Services. A popular, wellloved colleague and a real gentleman, Allan is missed by family and friends. Chris Lack, former technical director of Elta Fans, died in November following a battle with ill health. He joined Elta in 1984 as a technical manager and played a crucial role in the development of the company’s impeller ranges. He retired in 2010. David Ball, chairman of Elta Group, said: “Chris was a key part of a team of individuals who were the driving force behind the position and integrity and reliability that Elta Fans upholds across the world today.”

CIAT UK has joined forces with Toshiba Carrier UK to develop an integrated air handling unit (AHU) and direct expansion (DX) system.

CAREL OFFERS INTEGRATED PROTECTION Carel has introduced a new series of speed drives for DC compressors. The manufacturer says PSD2 comes with unique integrated and certified compressor protection to guarantee unit safety, with external protection devices no longer needed. With PSD2, thermal overload devices (Klixons), circuit breakers (thermal over-current relays) and electromechanical devices (contactors, if used exclusively for compressor protection or activation in the event of overpressure) are no longer required, resulting in cost savings, less space requirements and simplified wiring. The drives guarantee compliance with IEC and UL 60335-1, where applicable, as well as IEC and UL 60730-1, thanks to the integrated protection. Compliance with these standards, as well as guaranteeing safety and protection for users, is a legal requirement for all manufacturers. In addition, the “safe torque off” (STO) input is certified according to EN13849-1 for use with safety devices, such as high pressure switches.

Carrier picked for prestige project Carrier’s AquaForce Vision 30KAV chiller has been chosen to provide air conditioning for the new International Convention Centre Wales (ICC Wales). The project at the Celtic Manor resort is an £83.7m joint venture between the resort’s owners and the Welsh Government. The new venue, which opens this year, will accommodate 5,000 delegates and includes a 4,000sqm pillar-free main hall, a 1,500 seated auditorium, 12 flexible meeting rooms, a double-height glass atrium and a 2,500sqm plaza for outdoor events. Two Carrier 30KAV chillers equipped with Greenspeed Intelligence inverter-driven screw compressors have been selected to air condition the new facility, each delivering 791kW of cooling. They are being deployed in a duty-share configuration, with each chiller sized for 58% of the diversified load to provide resilience and continuity of cooling. Carrier says the 30KAV offers energy savings of 25-35% per year compared with conventional chillers, with smart energy monitoring enabling users to track real-time electrical consumption, cooling output and instantaneous efficiency ratios.

Cooling system fit for purpose Coolair Equipment is helping fans of a new fitness craze to keep cool. The contractor’s Cannock office provided energy efficient cooling and ventilation packages from manufacturing partner Mitsubishi Electric for the roll-out of seven Blaze Studios at David Lloyd clubs in England, Northern Ireland and Holland. The studios have been designed for Blaze, a new workout class that combines mixed martial arts, intense cardio and strength training synced to upbeat motivational dance music. The contract with PDS Design & Build of Wakefield, worth around £160,000, involved collaborating in the design and installation of the latest comfort cooling and heat recovery ventilation technology for seven Blaze Studios across England, Northern Ireland and Holland. Coolair installed a twin direct expansion (DX) split system incorporating four-way-blow cassettes to directly cool incoming air, along with a Lossnay unit mounted above the ceiling to extract the stale air and replace it with fresh incoming air heated by the outgoing air, in each Blaze Studio.

RANKINE CONFERENCE 2020

The Institute of Refrigeration will be hosting the International Institute of Refrigeration Conference, Rankine 2020 - Advances in Cooling, Heating and Power Generation, in Glasgow next summer. It coincides with the bicentenary of the birth of scientist William Rankine and will explore the synergy between the disciplines of Organic Rankine Cycle (ORC) and Refrigeration Air Conditioning and Heat Pumps (RACHP), with a view to generating a flow of ideas between the two fields. The conference, organised in association with the Knowledge Center for Organic Rankine Cycle and IESIS, will take place from 26-29 July 2020 at the University of Glasgow, where Rankine worked and studied. It will provide a platform to discuss the shared environmental challenges being faced today and there will be an anticipated 120 papers which will give delegates insights into new opportunities to deliver efficient, sustainable and environmentally friendly solutions. The event will look at Rankine's ground-breaking research to see what modern engineering can learn from this great Victorian innovator. It will also offer a forum where the different disciplines of power generation, refrigeration, air conditioning and heat pumps can come together to discuss their common challenges. www.rankine2020.com

Compact solutions from Trane Trane has launched three new compact chillers and heat pumps below 400kW for heating and cooling small commercial buildings, industrial facilities and industrial processes. Trane says the City products are 38% more efficient at part load than the 2021 Ecodesign requirements, future-proofing building owners’ investments. They are designed with R1234ze refrigerant and use renewable energy, geothermal sourced water and waste water to deliver heating capacity up to 80 degrees Celsius. Meanwhile, Trane has also introduced a new line of high efficiency large air-cooled heat pumps and says the CXAF units can fulfil both cooling and heating demands of medium to large sized commercial buildings and deliver best in class efficiency levels. The heat pumps are available in capacities ranging from 280 to 700 kW and can operate down to -15C producing hot water of 40-45C without the need for auxiliary heating. Trane has also launched Airfinity XL, a larger addition to its range

HPA BACKS EFFICIENCY CAMPAIGN

The Heat Pump Association (HPA) is backing a campaign for improved thermal efficiency in all buildings to reduce energy use. Renovate Europe, a political campaign group targeting an 80% reduction in energy use in buildings across Europe by 2050, has reported that the EU is well behind target, particularly in the domestic sector. There are an estimated 200 million dwellings in the EU in need of renovation and improved energy conservation measures. The current rate of renovation is 1% per annum whereas 3% pa is required to meet the 2050 target.

HPA president Graham Wright said: “Improved insulation and energy efficiency of dwellings makes sense whatever the heating system deployed since this will reduce emissions and fuel costs regardless of technology. Although there is an urban myth that heat pumps can only be installed in highly thermally efficient buildings, there can be additional benefits for heat pumps when retrofitted in renovated buildings.”

CAMFIL WELCOMES EUROVENT UPDATE

ECODAN DELIVERING COMMUNITY COMFORT A new residential development in Manchester is meeting environmental planning requirements with an Ecodan system from Mitsubishi Electric providing community heating to 105 homes. The Aaben development in Hulme is a mix of apartments and town houses. The original design was based on a ground source heat pump, but the costs proved prohibitive for the required budget, so design consultant Engineering Design Partnership (EDP) recommended the Ecodan system. Proline installed eight CAHV-P500YA Ecodan systems on the main roof of the development. These provide hot water to a heat interface unit located within each dwelling, providing hot water and heating for the occupants. Each tenant is charged accordingly via a heat meter measuring how much heat energy is taken from the network. The system has a capacity of 344kW and can operate at sufficiently high temperatures to provide heating and domestic hot water. A 6,000-litre buffer also enables the system to store energy for short peak demand periods.

INVERTER DRIVEN CHILLERS FROM CLIMAVENETA

Mitsubishi Electric has added two new chillers to its Climaveneta line-up. The i-NX air-cooled range is offered in both standard and low noise options, whilst the smaller i-BX air-cooled range is available in both single and three phase variants. The new models employ inverter driven compressors which ensures maximum efficiency at partial loads. The i-BX range offers capacities from 4kW to 35kW to deliver flexible and reliable units that adapt to the most diverse load conditions, whilst offering accurate temperature control and high levels of energy efficiency both at full and partial loads. All of the hydraulic components for installation are also already included within the outdoor unit reducing added cost. For larger applications, the i-NX delivers capacities from 43kW to 129kW to offer

Filter manufacturer Camfil has welcomed the new classification for air filter energy efficiency introduced by Eurovent. The Eurovent Energy Rating 2019, which came into force on January 1, is based on ISO 16890:2016, the international standard for particle filtration in buildings that replaced previous test standards on June 1, 2018. Under the new classification, the demands on energy efficiencies have increased, meaning many filters previously considered A+ have been downgraded to A, forcing manufacturers to improve filter performance and acknowledging the general developments within the industry since the original Energy Rating was introduced in 2015. Tobias Zimmer of Camfil, who worked with Eurovent to develop the new classification, said: “The energy consumption of air filters in general ventilation systems has become the focus of attention as energy prices increase, and demands to reduce CO2 emissions get tougher, not to mention our increased understanding of the effect of ‘bad air’ on our health and wellbeing.

These models incorporate a fixed speed scroll compressor and a scroll inverter compressor working together in the same circuit, with the promise of greater levels of efficiency than traditional fixed speed compressors systems. The i-NX low noise version delivers a reduction of up to 7dBA over the standard models, increasing the flexibility of where systems can be installed, which is becoming a major factor in today’s congested urban environments.

HY-EXPECTATIONS Steve Davies of JAVAC explains the benefits of the REFCO HY-EX-6 hydraulic tube expander. Refrigeration tube expansion has for many years been achieved with the plier style of expander. These are very common but have drawbacks and limitations, particularly in tight spaces with the space needed to expand the copper tube by force. REFCO addressed this problem with the recent introduction of the HY-EX hydraulic tube expander. The HY-EX-6 hydraulic tool kit with 6 expander heads covers all imperial sizes tubes of 3/8”, 1/2”,5/8”, 3/4”, 7/8” and 1 1/8” diameter. The soft handle rubber grip and single handed operation gives easy and accurate swaging for all sizes. The set includes a sturdy deburring tool and is delivered in a handy foamlined plastic case. Using hydraulic power, this lightweight expander makes a perfect expansion of soft copper and aluminium tubing with only a few operations of the pump trigger.

As an added benefit, the HY-EX-6 can be upgraded to the HY-EX-7, which includes the 1/4” head and the HY-EX-10 is also available with extra 5/16”, 1 3/8” & 1 5/8” heads. All sizes are also available in metric from 6mm to 42mm.

Complete package The complete package for all applications, with a total of 13 different sized imperial heads being available, this tool makes the installer’s life much easier on site. The REFCO HY-EX is a flexible robust expander tool for the HVAC industry and gives engineers a range of options for completing swaging of copper to the highest standard, helping to prevent future leaks and problems.

Easy single hand operation The hydraulic mechanism and release button makes one-handed swaging possible in the smallest of spaces and at any angle or elevation. Simply select the correct laser-engraved expander head, thread it onto the tool, and make a quality swage.

Small space capacity The compact pistol shape allows it to fit into the smallest and hardest to reach places at an angle of 120 degrees, plus the HY-EX system requires less effort than conventional tube expanders and offers complete flexibility. The interchangeable heads fit all common HVAC/R Imperial size copper tubing, but heads for all metric size copper tubing are also available, with sizes ranging from 6mm to 42mm. The HY-EX is compatible with the REFCO standard expander system and most other tube expander heads, making this a great upgrade to existing expanders.

R32 now mainstream but are you ready?

Air conditioning trainer Ben Bartle-Ross looks at what installers need to know about the refrigerant. as the main heat transfer medium and therefore removes any refrigerant from the vast majority of occupied spaces within buildings. We’ve had huge interest in this as it still provides the only R32 VRF solution for large scale applications.

Training and support

As a trainer, I see lots of installers both young and old and I’m still getting questions about the ‘new’ refrigerant, R32, which says to me that some in the industry are yet to embrace the change and the opportunity it brings. We know there is still a lot of R410A equipment on the market and this will be the case for a few years to come, so there is still good business to be done for installers in the short term. But looking further ahead, what opportunities to grow your business are you missing out on by not getting to grips with R32? “R32 systems is rapidly changing the air conditioning market here in the UK”

Transitioning market Certainly when it comes to our big corporate customers, most of them have embraced R32 models because they want to benefit from using equipment with a lower global warming potential (GWP). In the main, these models are also more efficient, bringing even more performance

We’ve been including R32 in our training course for several years now although any F-Gas qualified installer will have the skills necessary to deal with this. I therefore make a direct appeal to anyone in the industry who has yet to get their head around R32 because they are missing out a growing area of work for their business.

and benefits to customers. They do this using about 20% less overall refrigerant as well which helps with general installation costs. This means there will be savings in running costs to benefit from as well – something that customers both large and small can benefit from. There is now an R32 solution in almost all kinds of RAC and PAC air conditioning systems, including our own recently launched Mr Slim Standard Inverter and Inverter models which join the hugely popular R32 Power Inverter units. Not forgetting the technological advances as well, with indoor units that come with built-in sensors that can detect the temperature of individuals in the room and tailor the air conditioning to suit. So, there’s little to stop most jobs converting to R32 now with the choice of indoor and outdoor units available.

Final thoughts The introduction of R32 systems is rapidly changing the air conditioning market here in the UK and it affects anyone who uses it, commissions it, designs, installs or maintains it. This change is therefore coming to a building near you soon, especially as more and more customers realise that they notice little difference – apart from lower carbon emissions, higher efficiency and lower GWP. So, if you haven’t embraced R32 yet, please sign up for one of our training courses and make sure you are ready.

What about VRF? For larger systems, R32 has posed technical challenges for most manufacturers and so far, no manufacturer has released a VRF system utilising R32 – with one exception. The notable exception is our own Hybrid VRF system of course, which uses water

The quest for a greener gas Every right-thinking person agrees that global warming is a danger to the planet but there are ways for installers to help reduce its impact, says Christian C Rudio, European director of portfolio management, YORK HVAC. Unacceptable

There is a fundamental paradox at the heart of the chemistry of refrigerants – improving one element of a refrigerant gas means another will suffer. Using a refrigerant with a low global warming potential (GWP) to reduce the impact of global warming, for example, will probably mean the gas is more flammable (although this flammability remains low compared with a hydrocarbon, such as propane or butane). Over the last decade or so, the industry’s focus has been on reducing the GWP, which is a relative measure of how much heat that specific greenhouse gases trap in the atmosphere standardised to carbon dioxide (CO2) (which has a GWP of 1). Fluorinated (or F) gases are manmade gases used in a range of industrial applications including refrigeration and fire protection; there are three groups – hydrofluorocarbons (HFCs), perfluorocarbons and sulphur hexafluoride. F gases used as refrigerants are particularly brutal in terms of their greenhouse effect with GWPs of 1500 to 4000 (that is 1,500 to 4,000 times more powerful than CO2). That’s why efforts to regulate them have grown over recent years.

"It is very important to find the right balance between low GWP and efficiency when looking at alternatives"

However, as the GWP of a refrigerant (or refrigerant blend) falls below about 1000, these products tend to start exhibiting flammability, albeit low. So, the only way to have a non-flammable fluid is to accept a higher GWP. The trouble is, this has become unacceptable under environmental rules, including the F-Gas Regulation (see box on facing page). As a result, in recent years, the HVAC industry has invested heavily in the development of products using nextgeneration refrigerants and this trend is set to continue. For example, my own company, YORK, has launched the YLAA scroll chiller, available with low global warming potential (GWP) R454B refrigerant from 190 to 530kW cooling capacity. R454B is the lowest GWP replacement for R410A and provides similar properties and operating performance without major modifications to equipment design. With a GWP of 476 (75% lower than R410A), R454B is a next-generation refrigerant that provides the same capacity, but it operates at a higher efficiency than R410A as well as

The YORK YLAA scroll chiller and (facing page) the YZ centrifugal chiller

offering incomparable performance in both normal and high ambient conditions. R454B is a hydrofluoro-olefin (HFO) based refrigerant. This means it offers the best possible balance of properties to replace R410A in positive displacement, direct expansion air-conditioning, heat pump and chiller applications.

Efficiency There are also other alternative refrigerants including R513a or R1233zd. YORK’s YZ magnetic bearing centrifugal chiller, for example, is optimised for use with R1233zd(E) refrigerant – a low-pressure fluid that is also low in toxicity, nonflammable and has a GWP of 1. But, so far, only a few next-generation refrigerants have been classified as nonflammable. Next-generation refrigerants classified as being mildly flammable can be used safely, but some building owners may have concerns about using them. Hence, we can expect greater awareness and training on the use of mildly flammable refrigerants, as well as continued research into non-flammable alternatives. But there really is no need to worry about using low flammable refrigerants because are very difficult to burn. They can, for example, be ignited with a bare flame, but as soon as the flame is taken away it goes out; the flame doesn’t propagate in a way that it would with a hydrocarbon such as propane or butane. Finally, bear in mind that low GWP refrigerants impact on the efficiency of the units to which they are installed, which tends to mitigate against the other important regulation – Ecodesign. That is why it’s very important to find the right balance between low GWP and efficiency when looking at alternatives. Remember that 95% of the emissions are related to the indirect effect coming from energy use.

THE F-GAS REGULATION IN A NUTSHELL F-Gas is a European Union (EU) regulation on the use of fluorinated (or F) gases like HFCs. The original F-Gas Regulation published in 2007 was designed to reduce emissions from F gases, but it only really involved actions like leak testing, monitoring and servicing systems. The only true ban it introduced was that automotive air conditioning would have to move to a refrigerant with a global warming potential (GWP) of less than 150 for new models by 2012 and for all cars from 2017. The second F-Gas Regulation, which came into force in 2015, introduced a phase-down mechanism involving a gradually declining cap on the total placement of bulk HFCs on the market in the European Union. The fundamental aims of the latest regulation include: • Better containment of F gases. • Recovery of F gases from products and equipment reaching the end of their life. • Training and certification of technical people and companies working with F gases. • Reporting of production, import and export data within the EU. • Labelling of certain products and equipment containing those gases. The overarching objective of the latest F-Gas Regulation is to contain and reduce emissions through responsible refrigeration practice. To this end, it sets out caps and phase down schedules for the sale of F gases. So, in 2015 there was a starting point volume allocated to companies that had placed F gases on the market between 2009 and 2012. They were given a proportion of the ‘quota’ of gases allowed based on sales. In 2016 and 2017 respectively there was a 7% reduction. However, the big reduction came last year with a 37% reduction in quota. By 2030, only 21% of the current amount of HFC refrigerants used by the industry should remain in circulation.

Working with a passion David Todd visits Aermec in Italy and discovers that the manufacturer has its own way of doing things. Business success can be measured in different ways. Increasing profits, growing market share and keeping hold of existing customers can all provide valid evidence that a company is heading in the right direction. But less obvious indicators, like a contented and committed workforce and sustainable long-term strategy, can be just as important. Anyone who spends time at the Italian headquarters of air conditioning manufacturer Aermec would probably say it has the balance exactly right. Export sales area manager Michele Gioachin and Aermec UK managing director Paul Lawrence acted as tour guides at the impressive 130,000 sq m factory and testing facilities at Bevilacqua, between Venice and Verona. And the welcome for visitors from employees at every turn revealed a unique culture which dates back to the creation of Aermec 65 years ago. Michele, raised in the neighbouring town of Montagnana, said: “We don’t refer to colleagues, they are brothers and sisters. We work with a passion and that passion comes from the top of the business.’’ If you ask the questions, or pore over the company literature, you will discover that Aermec is: ° The only independent air conditioning manufacturer in Europe ° The biggest air conditioning manufacturer in Italy, and ° The biggest manufacturer of fan coil units in Europe It has also seen regular and significant growth, with sales up from 103million euros in 2001 to 210m in 2017. Exports have increased to 49% of the output. But that’s not really the part of the story that Aermec enjoys telling. The team would rather focus on the way they go about their business. Targets are shared to prevent individual employees from feeling isolated and the talented chef who served up lunch had been moved from a role in the factory because he mentioned at an appraisal that it had always been his dream to cook professionally.

An extract from the company vision reads: “Aermec needs to have employees that love to work for us. Not like, but love, which means they work with passion regardless of their salaries.’’ That is a big ask and only possible if the employees feel truly valued and motivated. So how did Aermec get to where it is today? After emigrating to Brazil and then returning to Italy, Ettore Riello set up a manufacturing company in 1922 and produced his first oil burner in 1923. Fast-forward four decades and Ettore’s grandson, Giordano, produced the company’s first air conditioning unit in 1961 and created the Aermec brand in 1963, moves which the company feels give it a valid claim to being possibly the first air conditioning manufacturer in Europe. Giordano is now chairman of the company and, at the age of 90, is still looking ahead to the next five years. As Michele said, the passion comes from the top of the business. Aermec remains wholly owned by members of the Riello family, with Giordano’s children Alessandro and Raffaella running the business. It forms part of the Giordano Riello Group, which has more than 1,600 employees in six manufacturing companies and five international sales companies, including Aermec UK, plus 70 distributors worldwide.

Robotics More than 90% of all Aermec products are made at the factory in Bevilacqua, a measure of the commitment to the local community and economy. Ignoring the obvious temptation of moving manufacturing elsewhere, Aermec continues to invest heavily on home turf with impressive levels of robotics and automation, along with some of the most advanced testing facilities to be found anywhere in the world. That level of

Up to 36 of the 96kW WWM units can be combined and, importantly, each will fit into a standard goods lift

EXCITING TIMES FOR AERMEC UK Paul Lawrence recently celebrated three years with Aermec UK, latterly as managing director after initially joining as sales and service director from Carrier. Although the company has completed numerous significant projects, including Wimbledon’s Centre Court, its profile in the UK has been low compared to some manufacturers. But Aermec’s reputation is growing and Lawrence believes its modular chiller innovation and free cooling solutions for data centres will lead to further growth. He said: “I came to Aermec because of the unique culture and I firmly believe these are exciting times for the business in the UK. There will be a lot happening through 2019 that will help us to strengthen our position, although any growth will never be at the expense of listening to our customers and delivering what they want.’’ Recent product additions include the NRV outdoor modular air-cooled chiller with free cooling coils, enabling up to nine 105kW units to be connected for a cooling capacity of 945kW. Lawrence said: “This is a real problem-solver for somewhere like London, where getting a single large chiller onto the roof can be very difficult. We already have lease and hire purchase options and we are looking at going into rentals with this product. “We offer a full support service in the UK, with 24-hour cover and 4-hour response, and 35% of that servicing is for data centres.’’ Further modular development arrived in the shape of the award-winning WWM heat pump chiller for indoor installation. Up to 36 of the 96kW units can be combined, giving up to 3.45mW of cooling. The modules each boast high-efficiency scroll compressors and, crucially for many applications in buildings with restricted space, will fit into a standard goods lift. Lawrence added: “There are so many applications for modular chillers, in particular where large chillers are located in either basements or high-level plants rooms that are difficult to access.’’ Nine NRV chiller modules can be connected for a cooling capacity of 954kW

testing helps the factory achieve a fail rate of 0.003% Robots and technology aside, when it came to improving efficiency at the factory Aermec worked with consultants from Porsche, who said significant improvements could be achieved with relatively small changes. By taking on board suggestions such as building templates for regular welding tasks and ensuring all tools are kept in the same position at every workstation, efficiency has since risen from around 80% to 95%. A self-contained section of the factory is devoted to fan coil units, with around 270,000 produced last year and the capacity to increase that figure to 400,000 according to demand. The core of the business, though, is an extensive range of chillers and heat pumps, with the 22,000 shipped in 2017 making up more than 40% of sales. Aermec is proud of the quality of every piece of equipment which goes through the factory gates. There is equal pride in the way it got there. TECHNICAL EXCELLENCE Aermec prides itself on being a business driven by R&D and nowhere is that more evident than its testing facilities, claimed to be the most extensive in Europe. The largest climatic test chamber, top, certified to Eurovent and AHRI standard, can accommodate single air cooled chillers up to 2MW. It can also test to -20C to +50C, enabling Aermec to fully measure the performance of its free cooling systems. It is also able to offer data centre simulation testing. There is a full suite of other chambers, including semi-anechoic for sound power level and sound intensity mapping, above, and a ventilation chamber for heat exchangers. Aermec also works closely with external partners... an impeller for its fan coil units was designed in conjunction with aviation engineers at Padua University.

UK first for Daikin R32 chillers An office building in Berkshire has seen the UK’s first installation of chillers with Daikin’s Bluevolution technology, based on R32 refrigerant. The EWAT-B units replaced two R407C chillers serving chilled water fan coil units and air handling units in the two-storey Astor House building in Newbury. They were installed by Daikin D1 Partner Klimatec, which had upgraded a similar installation for a neighbouring building in the business park to Daikin R410A units before the R32 chillers became available. Klimatec director Adrian Griffiths said: “The new technology appealed to us because of its increased energy efficiency and reduced refrigerant requirement. It was also an opportunity to future-proof Astor House because of the lower global warming potential of R32 in comparison with R410A.” The new generation of high efficiency air-cooled scroll chillers improve seasonal

The EWAT-B units are based on R32 refrigerant and feature Daikin's Bluevolution technology

energy efficiency ratios (SEER) by 10% in comparison with the previous R410A range. They are available for cooling only and heat recovery applications from 80kW up to 700kW cooling capacity at nominal conditions.

Daikin offers two efficiency versions (Silver and Gold), and three sound configurations (Standard, Low and Reduced) – as well as full customisation on projectspecific requirements. Options and accessories include refrigerant leak detection, fully integrated hydronic kits for fixed flow or variable flow operation and partial or total heat recovery for sanitary hot water production. The series is compatible with the Daikin on Site cloud-based remote monitoring platform. Master/slave functionality is standard, allowing sequence management of up to four units on one system – without the need for external control devices. The Intelligent Chiller Manager (iCM) option caters for more complex sequencing installations to maximise total plant efficiency.

DAIKIN ALTHERMA 3

JGR BUILDING SERVICES

Daikin’s Bluevolution technology combines highly efficient compressors with the energy efficient and environmentally friendly refrigerant R32, ensuring the Altherma 3 delivers exceptional performance. The Daikin Altherma 3 is available in 4, 6 and 8kW versions. The split wall mounted unit is a flexible system and includes an optional connection to deliver domestic hot water. It can be combined with a separate domestic hot water tank of up to 500 litres, with or without solar support. The integrated controller includes the “Daikin Eye’, which constantly displays the status of the unit. Performance of the single fan, low-height outdoor units has been enhanced by increasing the heat exchanger surface area by 9% and by incorporating a new-design fan motor and a hermetically sealed swing compressor. The units also have additional corrosion protection. The outdoor units can extract heat from the outside air even when the temperature is -25°C. Systems can deliver temperatures up to 65°C, which means water is stored at 60°C, reducing dependence on direct acting immersion heaters and thus reducing energy costs. The range is A+++ rated, with a heating efficiency of 5.1 COP at 7 - 35°C and a DHW efficiency up to COP 3.3 (EN16147. Its weatherdependent set-point controls and inverter compressors maximise the system’s efficiency, ensuring consistent room temperatures.

JGR Building Services chose two HT R744 CUBO2 Smart transcritical condensing units from SCM to trial a non HFC alternative system for convenience/petrol forecourt applications with Lincolnshire Co-op. The units provide cooling for five 5 Pastor Frigor HT cabinets with MPXPRO controllers and one HT cold room with an 85 bar g LU-VE evaporator on an UltraCella controller. The cabinets and cold room are fully networked to the units. An RDM controller monitors the cold room and cabinet temperatures and plant fail inputs and is connected to an RDM data manager for local and remote access.

Energy efficiency This is an R744 transcritical solution utilising advanced, complex software which is as simple to install as the traditional HFC units it replaces. The result is a high efficiency, reliable installation. The potential for leakage for is minimised by rated pressure of 80 bar g on the intermediate and low pressure parts of the system, virtually eliminating the venting of R744 if the system is shut down for any reason, all brazed joints in the construction of the condensing unit (apart from machine-made mechanical joints for transducer connections), and K65 tube and brazed joints for interconnecting. Energy efficiency is maximised using a Carel control system which accurately matches the unit capacity to the load. CMYKCMYK / .ai / .ai CMYK / .ai

34 Everything you need for the supply, installation an Focus on flammability air conditioning and refrigeration system R E F R IGE R A N T S

While increasing numbers of lowGWP fluids are being developed, more and more products on the market are classified as flammable. How are these fluids classified? What measures should be taken into account? What fluid charge can be loaded into equipment? This article from Climalife aims to shed light on the subject, particularly on A2Lclassified refrigerants.

Refrigerants are safety classified according to ASHRAE 34 standard, using approved test methods to assess their toxicity and flammability. The classification from the ISO 817 standard is used to identify these categories. The letter indicates the level of toxicity, A= low toxicity refrigerants and, B= the higher toxicity ones, whilst the number indicates the level of flammability, 1= Non-flammable, 2= flammable, 2L= lower flammability and 3= higher flammability. With the need of F-Gas to move to lower GWP refrigerants, a new group was created some time ago with a classification of A2L and is being integrated step by step into various standards. This is particularly the case with the latest revision (2016) of the EN378 safety standard about environment of refrigeration installations and heat pumps, recognising the A2L classification and allowing for greater charge sizes than A2 and A3 refrigerants based on the lower flammability limit. Examples of A2L refrigerants are R1234yf, R32, and R455A. A requirement of an A2L refrigerant is that it has a burning velocity below 10cms/second and they have a restricted flammability area compared to A2 and A3 refrigerants. By combining these various criteria, the final classification is shown in this ASHRAE classification diagram.

A2L fluids: how to use them and for which applications

A few examples of applications: ° R32 is recommended as a replacement for R410A in new split systems with charges of less than 3kg. R32 cannot be used as a drop-in replacement for R410A because the thermodynamic characteristics and its classification as an A2L-category refrigerant requires design changes. ° R1234yf is widely used in car airconditioning systems for all enginedriven vehicles produced since 1 January 2017. ° R1234ze is now used as a replacement for R134a in new installations adopted by most chiller manufacturers. Its properties are perfectly suited for high-temperature applications. ° A2L blends containing R32, R1234yf or R1234ze have been developed for other applications and have been certified or are in the process of being approved by equipment manufacturers. R455A and R454C in particular are being used, mainly as a replacement for R404A in commercial cooling systems, as well as in industrial applications. R452B and R454B are considered potential alternatives to R410A.

And much, much more! Under European legislation, very lowGWP fluids must be used for certain applications, both currently and in the future. In order to meet these requirements, producers have thought ahead and developed new HFO molecules in order to achieve a global warming potential of less than 1. But the lower the GWP, the higher the flammability. A compromise therefore had to be found between flammability and GWP in order to meet professionals’ needs as effectively as possible and provide solutions that were both environmentally friendly and efficient. The new A2L fluids can be used for many applications and various different processes – as could HFCs and HCFCs – while at the same time complying with current legislation and recommendations associated with their low levels of flammability. Currently, they must only be used with new purpose-built equipment or with systems specially designed to operate with these products. Under no circumstances should a system operating with a non-flammable fluid be retrofitted to run on a flammable fluid without carrying out studies or preliminary reclassification and authorisation in order to ensure continued compliance with current regulations.

A2L fluid charges: which reference should be taken into account? Fluid charges in refrigeration and airconditioning equipment are governed by international and European standards, as well as local regulations. For equipment manufacturers, for example, the main priority is to ensure compliance with the product’s safety standard (eg: the EN 603352-24 standard for domestic refrigeration appliances). If the new A2L classification is not incorporated, the second priority is to use the group’s safety standard. The reference in use today is the European EN378: 2016 standard. This does not apply to systems designed before the date on which it came into force. It does, however, apply to extensions or alterations carried out on systems after its publication, or in the event of systems being transferred and then used on a different site. It introduces the concept of risk assessment. The EN 378 standard can be used to calculate an installation’s maximum charge, taking three criteria into consideration: the characteristics of the refrigerant selected, access category and equipment location.

° Calculations are for guidance only and do not cover all the details specified in the EN378 standard. Individual companies must ensure they comply with EN378.

Maintaining equipment with A2L refrigerant charges The relevant training is mandatory for technicians and personnel. To ensure safety when working on systems in enclosed areas, a few best practices should be adhered to, for example: ° Install safety and ventilation systems that are appropriate for the location and for A2L-category fluids. ° Install a leak-detection system in the working areas. ° In the event of an accidental leak, ventilate the area before entering it. Use breathing equipment, if necessary. A2L-category fluids must be recovered for compliance with regulations. They must be packaged in special packaging for flammable fluids, and then labelled and identified as such in order to prevent any accidents. The maintenance equipment used will

depend on the type of systems concerned. Although certain tools, such as hoses and manifolds (care should be taken to avoid contamination) may be used, tools incorporating electric circuits or motors must be specifically designed for use with A2Lcategory fluids, and must be in compliance with local regulations (ATEX, for example). Vacuum pumps, recovery machines and leak detectors, for example, must meet specific requirements if they are to be used with A2L-category fluids. Never use equipment designed for A2L-category fluids to handle A3-category flammable fluids.

Goodbye virgin R404A A-Gas managing director John Ormerod on progress being made by the industry to meet the new challenges laid down by the F-Gas Regulations. Change can be unrelenting in the refrigeration industry. The F-Gas Regulations move into a new gear in 2020 and installers and end users will need to understand fully what’s happening and how it will affect their business over the coming years. Next year there’ll be a ban on the placing on the market of stationary refrigeration equipment using high GWP refrigerants (>2500 GWP) with an exception for equipment operating below -50°C. The ban on the use of virgin refrigerants with a GWP of more than 2500 will give the industry plenty to think about. Irrespective of the size of the system, this means you will be unable to install refrigeration equipment that uses gases above this threshold. This effectively brings the installation of new R404A equipment to an end.

of CO2 equivalent – that’s equal in amount to approximately 10kgs of R404A. Users of equipment still running on R404A could be forgiven for feeling confused with all these thresholds that mean you can service smaller equipment with virgin R404A but not larger equipment. If the system contains a charge of gas that’s more than 10kg of R404A the ban on servicing that equipment with virgin product will mean that an alternative low GWP refrigerant is needed. The good news is that this is not the only option as reclaimed R404A can be used up until 2030, regardless of the charge size. There will also be a ban on servicing existing equipment with virgin refrigerants that have a GWP of more than 2500 and where the charge is greater than 40 tonnes

Less pressure I strongly suspect that refrigerant suppliers will simply remove all stocks of virgin R404A from sale and switch to reclaimed

REFRIG ERANTS R404A. In truth this will make it easier for the contractors who will at least know that they can use all they are buying without falling foul of the regulations. We’ve passed through two years where there’s been a great deal of uncertainty about refrigerant availability and if there will be sufficient amounts of the new generation gases to support the phase down. What 2018 has taught us is that it’s going to be a mixture of new – and reclaimed refrigerants – that will support the transition away from high GWP gases. There’s less pressure on supplies and what has emerged is that the market has now stabilised and we can plan for the future with some degree of confidence. One thing you can be certain of is that this year the major refrigerant suppliers will say goodbye to virgin R404A. It is significant that the big supermarkets and many in the food processing industry have adapted well to the change. The last two years has seen this sector make considerable progress in converting to lower GWP gases and

utilising the A-Gas Rapid Recovery offering to ensure a smooth transition. Pretty much all the major supermarkets are well advanced on reducing their reliance on R404A. Most seem to be moving to interim replacements like R448A and R449A which will give them some breathing space to the mid to late 2020s.

Significant drop If you roll forward into 2021 and 2022 greater change is on the way. In 2021 there’s the next stepdown in the F-Gas quota when virgin refrigerant availability will drop by another 29 per cent, on a CO2 equivalent basis, taking the industry down to 45 per cent of the 2015 baseline level. This is quite a significant drop and some market volatility is to be expected. In 2022 the bar for the use of virgin HFCs is raised even higher when the threshold drops from

2500 to 150 GWP for hermetically sealed equipment and multipack centralised refrigeration equipment above 40kW. This will really ramp up the pressure on the industry. In the meantime, enjoy 2019 and the slow run up to the major changes taking place in the years to come. Our advice at A-Gas to installers and end-users, is don’t hesitate to seek advice from your refrigerant supplier, especially if you are unsure on how to react. Experts are on hand to help. The A-Gas website has a wealth of information to help you switch to a low GWP refrigerants. We are also happy to provide advice at the end of the phone. You can be sure that however difficult the journey may appear to be at the start, there is always help available to guide you in the right direction and a positive outcome. www.agas.com

Logicool is a technically biased and customer focused specialist distributor of Hitachi, Mitsubishi Electric and Panasonic air conditioning and heat pump products, including parts & spares. We excel in customer service and project support. Logicool promise an unrivalled and unbiased approach to all project enquiries, always providing a solution for every application. Established in 2008, Logicool are celebrating our 10th anniversary this year. The last 10 years have seen us witness numerous challenges and experience unforgettable high points that have made us what we are today. Formed in 2008, at the height of the recession, Logicool has grown into a £6.5m turnover business with 15 staff and a growing reputation in an ever-challenging market. The business retains a strong ethos based on values which promote respect, standards and teamwork throughout our involvement in the supply chain. Logicool sits in an almost unique place in the AC service sector. Only a handful of companies are able to offer the level of support and attention to detail that Logicool are able to offer. This positioning allows us to grow primarily through reputation. This unique offering can be explained as follows: The air conditioning supply sector in 2019 is split into two typical service offerings, both of which offer challenges for designer, the purchaser and especially the installer.

° T he “direct” market, where the contractor purchases the equipment only directly from the manufacturer ° T he wholesale market where the contractor purchases the air conditioning equipment and their installation accessories and ancillaries from a “one-stop shop” business model. The direct approach does not typically offer a quick turnaround response time for enquiries. Going forward, the onus seems to be shifting towards the contractor preparing their own quotations and selections rather than relying on the manufacturer to assist with their superior product knowledge. The wholesaler route offers more choice but less technical support and less product knowledge. This is due to the wholesaler having 50,000+ products in their armoury. The Logicool approach offers speed of response, pre-sales product knowledge and the after-sales technical support. We remain in favour of a phone which is answered in less than four rings by a person that introduces themselves. Quotations are dealt with immediately with same-day being a worse-case scenario. This is proven by Logicool spare parts division alone achieving sales in excess of £1.25m annually. In addition, we treat all enquiries equally and one of our mantras is that “it is never “only” a 2.5kW wall mount”. It is a customer enquiry. The size of the order or the margin comes secondary to issuing the quotation and selecting the correct equipment.

Our relatively small team have a combined experience of over 200 years’ experience in the air conditioning sector. Our technical support team are ex-engineers and each of them take individual responsibility to train the newer members of our team. We believe that modern businesses requires realistic thinking. This does not mean “blue-sky” ideas but working together and respecting our responsibilities and expectations. A supplier to the Building Services sector cannot rely on a culture of digital marketing. It needs to promote real communication and understanding of our customers’ requirements. We try to educate new staff with the reality that employees within the air conditioning sector cannot expect to walk into work with a plan. Everything changes by 9.00am and we, as a supplier to the HVAC market, need to be able to understand that environment and embrace the challenges that it presents to us daily. These facts represent the core of what and how we educate our staff. We try to understand our clients and offer the best possible service that they can expect. This isn’t always possible, but it is how we deal with things that either reduces or increases our reputation with the Logicool client base. We exist in a market which is presenting challenges that we have never faced before. Presently, F-Gas and Kigali do not offer us a clear view of what the marketplace will look like when we celebrate another 10 years. We understand that the air conditioning market may see very little growth over the next ten years and therefore we expect Logicool 2028 to look very different. We aim to continue to grow our air conditioning sales by taking more of the market share via our growing profile and commitment to great customer service whilst also focusing on emerging products and technologies.

We expect that this will include growing sales in heat exchangers, air to water, chillers, air handling units and IT cooling. What we will not do, however, is lose focus with the clients that have got us to where we are today. Our strategy is to grow together.

CDL’s newly opened 15,000ft2 head office has started bringing in stock, with the total level to be close to £2M

From modest beginnings a little more than a decade ago, Cool Designs Ltd has grown to become one of the UK’s largest independent air conditioning distributors. Early on the company notched up a significant accolade by becoming the first air conditioning supplier in the UK to achieve carbon neutral status. Darrel Birkett, founder and managing director, says: “Environmental factors are obviously a key driver in our industry, and early on weidentified this is a leadership issue. We wanted to put the businesson a carbon neutral footing not only because it’s the right thing to do as custodians of the planet, but to demonstrate it could be done, and could also be good for business.” Another key to its success has been its emphasis on customer service, and the provision of high quality training. In the past few years, more than 3000 engineers have attended its courses on technology, application and servicing at the company’s three centres around the country.

CDL relocated its head office in January 2019 offering an additional 10,000ft2 storage as well as increased capacity for training. Having well-established branches in the North East, North West and Scotland, where it employs some 28 staff, it is now looking to expand coverage further South, with local stocking to ensure the same level of rapid response as the rest of its network. Over the years, its biggest selling unit has been Toshiba’s RAVSM806KRT 7kW wall mount, an efficient, reliable workhorse used in a wide range of applications. To date, CDL has shipped some 6,000 of the units to customers across the UK. Flexibility is a core theme in CDL’s approach. Darrel says: “We understand that life and business are dynamic, and things can change and sometimes go wrong. We stay in close touch with our customers, and are responsive to changing needs and situations.” The company’s portfolio was expanded significantly in 2018 with the addition of CIAT products, adding a comprehensive range of HVAC systems to its established DX range. The addition has proved highly successful in its first year, widening

CDL has a reputation of being highly tech-savvy, and has harnessed its in-house digital skills to develop high quality online video training, bespoke controls and other customer enhancements. On the digital theme, do they foresee a time when orders will be placed directly online, without the need for human intervention? “That is possible now, and we are exploring ideas around this. However, I wouldn’t like to see the human element removed. The personal touch is important, and sometimes we can make suggestions that benefit our customer and the end user.” Whatever legislative and technical developments emerge, with its vision and customer-centred approach, CDL is laying the ground to build on its success in the years ahead.

the range of projects CDL can cover, effectively enabling it to offer a one-stop solution, from splits and VRF to AHUs and Fan coils – and even chillers. Is air conditioning still a good sector to be, and how does the future look? “It’s still a great industry to be in,” says Darrel, “but there are some obvious uncertainties to navigate. The situation over R32 is a case in point. The view emerged that this is an interim solution, and that something better will emerge in time. We await to see developments with interest.”

FRIDGENIUS - THE SMALL TOOL WITH A BIG AT Head Office Details: 293 Sopwith Crescent, Merley, Wimborne, Dorset BH21 1XQ

Fridgenius was established in 1995 by David Slydel, Managing Director. The company is a family business which is now run by his son, Chris Slydel. Under Chris’s leadership, Fridgenius has grown and fully established itself as the leading supplier of Solenoid Valve Operating Magnets – The Small Tool with a Big Attraction! The company has seen much growth and is proud to supply national and international distributors.

when recovering refrigerant from a plant that has already been decommissioned and the power removed. In emergency situations, such as the failure of a solenoid valve coil, it can be used to keep the system operating whilst a replacement coil is found. Proving to be a crucial and adaptable tool in an engineer’s toolkit, the Solenoid Valve Operating Magnet controls and assists in the installation process, commissioning and decommissioning of plant and machinery, and the recovery of refrigerants. The Fridgenius Solenoid Valve Operating Magnets are highly flexible, easy to use

The Solenoid Valve Operating Magnet was invented and designed in 1995 by David Slydel to solve the problem of operating a solenoid valve manually when a system is not under power. The Solenoid Valve Operating Magnets are available in three sizes, 10mm (up to 10mm stem size) which comes in white, 15mm (up to 15mm stem size) which comes in orange and 18mm (up to 18mm stem size) which comes in red. The Solenoid Valve Operating Magnet fits all make of solenoid valve. The Solenoid Valve Operating Magnet converts an electrically operated solenoid valve into a hand-operated valve in seconds and is the same shape and size of a large cotton reel. When the tool is placed onto a solenoid valve (with the coil removed), it causes the armature to open or close. This enables the valve and system to be controlled by the engineer. This eliminates the need to wire up the system or to worry about the correct voltage. It can be used

Why CO2 is a viable option

Carbon dioxide offers a wealth of benefits when used as a natural refrigerant, says Ed Whinyates of Stonegrove Refrigeration.

In a period of massive change for ozone depleting HFC refrigerants, the impact is being felt within the perishable goods industry. As a designer and installer, we appreciate how this is impacting on refrigeration installations. Because of regulation on the â&#x20AC;&#x2DC;phasing outâ&#x20AC;&#x2122; of certain refrigerants, it is important to work with customers to offer the best possible solution for their long term needs; this entails designing and installing plants with longevity. By moving away from environmentally harmful refrigerants towards installations using natural refrigerants - like ammonia (R717), propane (R290) and CO2 (R744) - we can future proof refrigeration equipment.

Natural alternative CO2 is is not new to refrigeration, with its initial use traceable back to the mid-19th century. However, with the advent of man-made refrigerants during the 20th century, the use of CO2 within the food and drink industry was vastly reduced

REFRIG ERATIO N with the introduction of CFCs and HFCs. With global legislation putting pressure on refrigeration users to reduce their environmental impact, the knock-on effect is a move away from both commercial and industrial HFC systems to natural alternatives. When used as a natural refrigerant, carbon dioxide has a wealth of benefits.

Myths surrounding CO2

There are some common myths surrounding CO2, one being that it is too dangerous in a refrigeration system. Given the wrong conditions, all refrigerants can potentially cause harm. With proper design and installation, CO2 is just as safe as any other refrigerant. There is also an assumption that it requires more in the way of leak detection compared to other refrigerants. CO2 does require leak detection, as it is colourless and odourless vapour, but this requirement is no more or less important than other HFC refrigerants. A third myth is that it is more expensive to install and operate. There is a very strong argument to say this is no longer the case.

Important and noteworthyÂ characteristics:

Non-toxic & non-flammable Natural refrigerants can sometimes be limited due to toxicity and flammability concerns. CO2 lends itself to applications when these issues arise (primary, cascade or secondary), so offers an excellent solution. Environmentally benign It has an Ozone Depletion Potential (ODP) of zero and an extremely low Global Warming Potential (GWP) = 1. This is directly comparable with other natural refrigerants; propane ODP = 0 GWP = 3 and ammonia ODP = 0 and GWP = 0 High pressure benefits Compressor capacity is significantly higher compared, for example, to ammonia. It has good potential for heat reclaim, which will help with refrigeration plant running costs. Compressors can be up to six times smaller than more traditional applications (R22 for example). It also has a higher suction pressure with improves efficiency. High refrigeration volumetric capacity This leads to a reduction in pipework sizes (up to five times that of 404A), and a significant reduction in suction line valve costs, so a big saving on installation costs.

High heat transfer characteristics This allows an evaporator to operate at higher temperatures. The lower temperature difference between the refrigerant and the air offers increased efficiency. This results in an increased capacity in heat exchangers. Material compatibility Because CO2 is an inert and stable substance, there are no concerns over chemical reactions with polymers. As it is non-corrosive with most materials there are very few differences to the materials used in HFC systems.

Inexpensive and readilyÂ available There are cost benefits when installing a CO2 system. With a high refrigeration capacity due to a high volumetric cooling capacity (approximately up to six times that of R404A), this has a positive impact on the compressor displacement and the sizing of heat exchangers and pipework. Smaller evaporators and condensers are required due to the high heat transfer, high pressure and density. Due to high discharge temperatures there is greater potential for heat reclaim. Because CO2 is a stable molecule there is a lower potential for decomposition within the refrigeration system, which gives it a much greater life span compared to HFC systems. The overall investment cost of a CO2 refrigeration installation has reduced in recent years and is now comparable to other refrigerants for both industrial and commercial applications. CO2 itself is inexpensive to produce and widely available.

Efficiency advantages It has been argued that it offers better operating conditions. It is not affected by higher pressure drops so the impact of long suction lines and liquid lines is diminished. The lower temperature differences between the refrigerant and the air increases efficiency. Lower compression ratios means the compressor doesnâ&#x20AC;&#x2122;t have to work as hard.

Solutions for CO2 in refrigeration

The first area where CO2 has made a successful comeback is within the industrial refrigeration sector, where it can be used either as the low-stage refrigerant in cascade installations or as a secondary coolant. Due to the continued advances in design and technology, it is also becoming a more viable option in the commercial sector - where in the recent past the only assumed solution would be man-made refrigerants.

Packing a punch

BITZER equipment helps deliver pizza plant solution with ‘game-changing’ ammonia system. Kevin Glass

Two BITZER ammonia compressor packs (ACPs) with a combined cooling capacity of 1.4MW are delivering high performance refrigeration for a major new pizza production plant in the north of England. The industrial scale single-stage pumped ammonia system serves all the cooling needs of the 60,000sq ft facility for one of the UK’s leading food companies. The installation by Integral UK uses the BITZER ACP systems to deliver multi-temperature cooling for the plant’s 2°C chill store, -5°C spiral chillers, -18°C freezer cold store. Integral UK designed the multi-compressor packaged ammonia solution to maintain the highest levels of efficiency, whilst minimising payback time on the project. Resilience was also a key design factor, with built-in standby capacity provided by the BITZER design combining with the company’s renowned reliability to ensure continuity of cooling around the clock, 365 days a year. The ACP units selected have three compressors per pack, giving standby capacity and resilience needed for such critical process applications. It enables engineers to service a compressor while the others remain operational, reducing process down-time and improving life-cycle cost. Following commissioning earlier this year, the plant has operated smoothly and quickly established itself as the most energy efficient plant of its kind operated by the food production company.

BITZER ACPs.indd 56

Highest quality The ammonia packs are based on compact screw compressors, which BITZER says result in a smaller footprint than equivalent-capacity reciprocating compressors. In addition to the inherent efficiency of screw compressors, the speed of the lead compressor is controlled by an integrated variable speed drive (VSD), which significantly increases part-load efficiency and enables soft-start. Efficiency can be further enhanced with the addition of an optional economiser module. A further benefit for end users is that screw compressors have much longer maintenance intervals than reciprocating compressors, which substantially reduces the cost of ownership over the lifetime of the plant. Kevin Glass, managing director of

BITZER UK, said: “This superbly executed Integral UK project is an excellent example of how to harness the strengths of BITZER’s modern ammonia refrigeration systems to deliver an efficient, safe, resilient and costeffective solution. Ammonia systems have traditionally been built as one-offs, often in less than ideal conditions. BITZER builds ACP units in a pristine factory environment, ensuring the highest possible quality and integrity, absolutely necessary when working with ammonia. “The modular design means that contractors can quickly connect up ACP units on site with a few simple pipework and electrical connections. This dramatically speeds up with whole process of installation and commissioning. We believe it is a gamechanger for industrial refrigeration.”

HEAT PUMPS

Don't fall for the fiction

In the first of a series of columns for ACR Journal, Graham Wright, president of the Heat Pump Association (HPA), explores some of the stories casting doubt on heat pumps as a viable long term option and separates the fact from fiction. In 2018 the UK continued to commit to more energy efficient building practices and this was underlined in May in a speech by Prime Minister Theresa May, which committed the UK to reduce its building energy usage by half. Mrs May’s reference to more energy efficient buildings and smart technologies was certainly welcomed by the HPA, as heat pumps represent one of several environmentally friendly heating solutions for the long term. Although a major short term shift to solely heat pumps would be neither practical nor sensible, it cannot be denied that heat pump systems of all genres are capable of significantly reducing carbon emissions. Misinformation inevitably has led to concerns in some quarters over whether heat pumps present a suitable option for enough properties for them to be considered a viable long term heat source, but in my view the case for heat pumps was made a long time ago. We need to ensure that our focus on delivering heat pumps to the domestic market is sustained as it has been in the commercial sector with significant success and recognition in aspects of building design.

Fabric insulation One of the most common and longest running myths suggests that heat pumps only work with well insulated buildings. While it is true that heat pumps do work better in well insulated buildings, the same can be said for ALL heating systems, in the sense that this means less energy output,

wherever it is derived from, is required. However, if a building needs heating to a particular level then it will need a finite amount of energy (kWh) each year to achieve that, regardless of the source of heat. Hence the most optimal method to provide that amount of energy will need to be sought. You can find many examples of low energy, low running cost heat pump systems installed in thermally poor buildings, including Grade 1 listed buildings with no insulation and original leadlight glazing. A badly insulated building may require slightly higher flow temperatures than ideally desirable if existing heat emitters are to be re-used, which may reduce the efficiency slightly. Take an old Victorian house with no insulation in the cavity and 50mm in the roof void. If the radiators have been selected using a crude rule of thumb it may be they are massively oversized when working at say a 70°C flow (typical of condensing boilers). With no additional treatment of the building they could provide enough heat output at a reduced temperature of, say, 55°C from a heat pump, but that is not

the ideal operating temperature for a heat pump. However it’s discovered (by checking all the radiator outputs at 45°C) that by increasing the size of all of the radiators requiring a flow of, say, between 45-55°C, the system can run at design conditions at a maximum flow temperature of 45°C and satisfy the heat demand. Hence by uprating certain radiators the system is more efficient and this will result in lower running costs. Of course, by insulating the cavity the overall heat demand will reduce and now the existing heat emitters may be sufficiently sized to provide the new demand at a lower flow temperature that suits heat pumps. This will have the added benefit of reducing the energy demand for heating and hence reduce fuel bills, regardless of the heating system employed.

Floored understanding Another false belief that is widely expounded is that heat pumps only work with under-floor heating. In fact this is just a slight misapplication of a correct principle, the principle being that heat pumps work better with as low as possible delivery (load side flow) temperature. Under-floor heating can work effectively at flow temperatures of 35-40°C if correctly designed and the building can be effectively heated with a low temperature source (see above). Natural or fan convector heat emitters will generally need to be larger than previously or run at slightly higher temperatures, resulting in small reductions in efficiency. www.heatpumps.org.uk Next issue: Noise and the UK climate.

Making a difference How heat pumps technology can help transform the way we live.

Heat pumps have an important role to play in changing the way we build the homes of the future, according to Mitsubishi Electric. Consultants, specifiers, architects and housing associations attended an event at the company’s Hatfield headquarters. Among the presenters at Transforming the Housing Technology Mindset was architect, campaigner and TV presenter George Clarke, who is an ambassador for Mitsubishi Electric’s Ecodan air source heat pump. He said much of today’s housing was still built in largely the same way as the Romans and highlighted the advantages of using modern methods of construction (MMC), where buildings are produced in a factory environment and then constructed on site. He said this helped ensure the quality of materials and reduced building times. He said “When you look at almost all other aspects of our life, the pace of change and revolution has been exceptional. A government report released in 1997 recommended sweeping changes to the way homes are built and heated. When you consider this report was released a year before Google was founded, you only need to look at the technological revolution that followed for this to see how far behind the

housing industry really is. Unfortunately, the housing technology market has made very little progress since 1997. We need systematic change at a global, national, local and personal level to get houses to a standard they should be. It’s time for the housing revolution.”

Huge opportunity “Other industries have moved on, with staggering levels of R&D and disruptors coming in. We are still building houses like the Romans.’’ He also stressed the importance of convincing the public of the benefits of renewable options, including heat pumps: “Without education, nothing will change. The public need to understand and until we help to change that mindset, they will still order a gas boiler.’’ Also speaking was Professor Nick Whitehouse, an experienced fellow architect and part of the Build Offsite organisation. Mitsubishi Electric believes heat pumps technology is ideally placed to be used alongside MMC. Max Halliwell, Martin Fahey and Stuart Bell from the host company looked at the way we heat our

homes and how that is expected to change as we are forced to reconsider our reliance on fossil fuels. Martin Fahey, head of sustainability at Mitsubishi Electric Living Environmental Systems, identified heat pumps are a key technology in the move towards an electric economy and said properties off the gas grid should be moved very soon, according to the Committee for Climate Change. He added: “Demand for heat in the UK accounts for a third of all our carbon emissions and half of all greenhouse gases. This represents a huge opportunity and is an area that needs to change if we are to ever cut our own carbon emissions, and it’s an area that can change quite quickly if we apply the technology. Heating is one way in which we can take a step towards making a difference. We need a mix of low carbon heating solutions and better thermal efficiency of buildings. Embracing innovative and renewable heat sources, like air source heat pumps, we can become prosumers – both producers and consumers of energy.”

Market growth Max Halliwell, communications manager for renewable heating, described living with an Ecodan, having had one installed in the family home eight years ago. He also traced the development of the range from its arrival in 2007, with almost 60,000 since installed in the UK. It is now available from 4kW-48kW and the line-up includes the Ultra Quiet Ecodan, built in Scotland and launched this year, which the manufacturer says is based on 10 years of knowledge and sets a benchmark for others to follow. His thoughts on market growth were echoed by national specification manager Stuart Bell, who said heat pumps accounted for more than 50% of new heating installations in Germany last year, significantly ahead of figures for the UK despite a similar climate and population. He said a fully electrified UK heating market would see 425,000 air source heat pumps (ASHPs) installed in 2030 – around 20 times the current figue. Even moderate predictions would see 100,000 installations by 2030, he added, bringing the UK into line with the French market.

EFFICIENT BUILDING S

Education is key to change Andrew Slater predicts a major move towards more efficient buildings to protect the environment. As a new year rolls in, bringing with it a period of political uncertainty, one thing remains clear: the drive to improve the environment we all live in will continue. Whilst attending a series of seminars last year, I listened intently to some highly passionate, intelligent individuals showcasing their research. They discussed how changes to the built environment should take place, and the lobbying in government that seems to have fallen on deaf ears. One point right at the end of a Q&A session really stood out for me; a point that no one had a counter-argument for. It came from what I believe to be an undergraduate engineer. She stood up and said: “Whilst I understand perfectly the points from today, when I discuss these topics with my peers from other industries or professions, they only have knowledge from the mainstream media and so cannot understand fully how to utilise the buildings we provide them. We find ourselves so immersed in our own industry and our responsibility to solve all problems, do we not think it is better planning to educate tomorrow’s generation on the importance of reducing our carbon footprint and the methods of doing so?” The 2018 progress report produced by the Committee on Climate Change suggests that we need to reduce emissions by 3% as a whole each year to meet the 2025 and 2030, 4th and 5th Carbon budgets. Using 66% of all electricity produced, the built environment accounted for 19% of the total UK emissions in 2017, generated through both direct and indirect means. Even though the power sector has seen the greatest reduction over previous years, a lot more progress directly within the building sector is required.

Increased responsibility April last year saw the introduction of minimum energy efficiency standards for domestic and non-domestic property, using restrictions on financial gain in forcing landlords to increase a building’s rating. Referencing the world renowned NABERS1 scheme in Australia, the Better Building Partnership (BBP) found a poor correlation between building rated efficiency and operational efficiency. Working alongside

of change reassures in that restriction, eliminating a clash of purposes between optimising the built environment’s efficiency and individual wellbeing.

Hindering development

forward-thinking consultant bodies and property estates, the BBP has started producing sample sites with a view to implementing in the UK. Building modelling and environmental simulation will be introduced as more and more focus is placed on operational efficiencies. Designs, manufacturers’ data and control strategies will be put to the test when the reality of operation is compared to simulation results. A prolonged building handover and optimisation will create a dynamic of increased responsibility from consultant, manufacturer and installer. Hopefully using more frameworks like BSRIA’s3 Soft Landings. Education is the key. A complete skillset will be critical and levels of upskilling in design, specification and commissioning have been identified as required across the UK. With operational efficiency a priority, a system will not just be able to be switched on and left to run, it will need to be controlled and regulated as designed. However, complete automation of a building poses its own complications. People want control of their environment, but with restricted manual control options. A firm understanding of why and how a building is reacting and the consequence

The Committee on Climate Change has advised that ‘low carbon heat’ should be promoted and headway is being made for possible heat networks. However, the push in the domestic heat pump market is expected to bigger than ever. RHI2 details, currently awaiting an update, but recently quite settled, give weight to convincing a nation of gas consumers to switch to renewable technologies. With the rise of ‘pop up’ renewable experts who follow government grants, we run the risk of ruining this sector before it has really taken off. Public conception of air to water heat pumps is that they are expensive to run and unreliable. The industry contains some fantastic products and is full of well-trained, reliable, competent people, but it’s a shame that the cheaper ‘pop up’ option from people who are only present short-term hinder its development. Introducing ‘mildly flammable’ refrigerant in the form of R32 to domestic AWHP is further reason to educate these individuals and companies. Education is critical to the development of any sector and we should remember that continuing professional development is just one side of the coin. We also have to think about how industry outsiders view and interact with us, and to ensure the broader knowledge of future generations. Without their co-operation, we can only achieve a fraction of what is possible with the buildings we provide. °A ndrew Slater is managing director of HVAC Communications. www.hvaccommunications.com

Off-site increasingly vital in the quest for quality Wider adoption of modern methods will be crucial if the building services industry is to meet increasing demand for its expertise, says BESA president Tim Hopkinson. Building engineering services will have to take a leaf out of the manufacturing industry’s book as it strives to deliver an increasingly challenging workload. Over the next two to five years, we will see modern methods of construction starting to redefine the way we work. Building engineering contractors will have to become less and less about people working on sites and more about digital procurement and design linked to off-site manufacture. Like product manufacturers, we will have to focus on producing more complete modules off-site. This will be partly driven by our acute skills and resource shortages, but also by a need to improve quality and compliance. Born of necessity, it will also herald a new era that will bring with it many technical, social and financial benefits – and make our industry a far more appealing career prospect for a wider cross-section of our population. Adopting more of a production line approach will allow us to develop a less disruptive supply chain management and payment model. Successful off-site construction depends on collaboration, which in turn will produce to a new contract model that removes old areas of conflict – like late payment. It should also ensure that the finished product works better in the long run – so addressing many of our performance and safety problems.

This, along with many of the other things that make our industry so unattractive to young people, will be transformed. Off-site construction is inherently safer, cleaner and more technologically driven – and if this makes it more profitable and less adversarial, building engineering services suddenly looks like a much more appealing career.

Transformation However, this is not just about medium to long -term transformation of our industry, there are also immediate problems confronting building engineering firms that must hasten the adoption of new ways of working. ‘Mega projects’ like HS2, Heathrow’s controversial third runway and two new nuclear power stations will put an increasing strain on our pool of available skilled manpower – and our departure from

the EU will step up the pressure still further. Heathrow is likely to need up to 15,000 site workers and the two planned nuclear power stations at Hinkley Point and Wylfa Newydd could each pull in more than 6,000 site-based technical staff. HS2 will absorb people from all over the country and it was recently reported that Crossrail was still recruiting M&E workers despite the ninemonth delay on the project being put down to purely train-related issues. These high profile projects have the pulling power and the budgets to attract the labour they need, but often at the expense of other employers who have their own commitments to fulfil. Next year engineering, infrastructure and housing projects of all shapes and sizes face the prospect of not being able to meet deadlines due to staff shortages. The industry is already at full capacity; there are tower cranes all over our major cities and we are continually being exhorted to employ more skilled people, but where are they going to come from? EngineeringUK says we need 1.8 million new engineers (in all fields) by 2025. The latest call from the Chartered Institute of Building suggested construction needs more than 150,000 new recruits by 2021 to keep up with the current demand. Increasingly, these figures look simply unattainable. In the past, the knee-jerk reaction would have been to flood projects with labour from

CO NSTRUCTION the EU. That will no longer be an option once the UK leaves, but on the other hand, that could well turn out to be one of the long-term benefits of Brexit. Rather than simply bringing in people with varying levels and types of qualifications, we will have to ensure that everyone has completed the right training and has appropriate skills in line with these new working approaches. We will still be short of people, but our lack of manpower will add fuel to the offsite revolution, which will also further improve quality. If you build something in a factory – rather than on a building site – you have a far better chance of ensuring it is finished to the right quality. You can manage the quality control process much more easily and provide better and safer working conditions for your people. The House of Lords has spotted the importance of a big shift to offsite and modular methods of constructon. Its Science and Technology Committee recently reported that offsite manufacture could improve productivity by as much as 70% while also delivering better and more energy efficient buildings.

"EngineeringUK says we need 1.8 million new engineers (in all fields) by 2025. The latest call from the Chartered Institute of Building suggested construction needs more than 150,000 new recruits by 2021 to keep up with the current demand. Increasingly, these figures look simply unattainable."

“There are clear and tangible benefits from offsite manufacture for construction, which make a compelling case for its widespread use,” said committee chair Lord Patel. “The construction sector’s business models are no longer appropriate and are not supporting the UK’s urgent need for new homes and infrastructure.” He highlighted that the construction industry’s current culture is not well suited to offsite methods and needs a radical overhaul. The report, Offsite Manufacture for Construction: Building for Change, attacked the fragmented culture of the sector and the lack of trust, which led to poor levels of the collaboration needed to make offsite manufacturing work. It also criticised the tendency for public sector procurers to put low cost ahead of “lifetime value”, which had often mitigated against adopting more modern approaches.

Uncomfortable truth The report highlighted the fact that off-site manufacture for construction provides clear and tangible benefits including: ° Better quality buildings and infrastructure ° Enhanced client experience ° Fewer labourers and increased productivity ° Creating more regional jobs away from large conurbations ° Improved health and safety for workers ° Offering building safety advantages— making it easier to ensure buildings meet quality assurance standards ° Improved sustainability of buildings and infrastructure ° Reduced disruption to the local community during construction. Off-site may address some of our immediate concerns with delivering existing and imminent projects, but it also requires significant long-term investment to really make inroads into some of our more fundamental problems. Not least, the current and future workforce will need

re-training. The Lords committee urged the government to work with the industry to make sure that new technical qualifications will close this skills gap and equip the workforce for off-site working. It also welcomed the Government’s commitment to changing its procurement models so that the public sector can procure for whole-life value rather than upfront cost. This, along with the Government’s ‘presumption in favour’ of off-site manufacture across five departments, will provide an important signal to the construction sector that there will be a consistent pipeline of projects, allowing companies to invest in off-site manufacturing facilities. Designers, contractors and suppliers must all have early involvement in a project for off-site manufacture to be successful. This requires a change in business models among both private and public sector clients. Off-site usually requires greater upfront investment than ‘traditional’ construction techniques, but it is better placed to deliver building lifetime benefits like energy efficiency and low maintenance costs. However, to secure these long-term gains procurers will have to wean themselves off the habit of always going for the cheapest upfront price. However, it is not only our clients who have to change. The uncomfortable truth for our sector is that many of the barriers to the greater uptake of off-site manufacture, such as a lack of collaboration and attitudes to risk, are cultural and can only be dealt with by the sector itself. That is our challenge and one that we should embrace. Tim Hopkinson is serving his second year as BESA president and is managing director of E Poppleton and Son.

Star's community spirit shines through Star Refrigeration has contributed more than £10,000 to good causes proposed by staff following the introduction of a formal corporate social responsibility scheme. The Star Community Involvement Programme is aimed at supporting charitable efforts, educational initiatives and community development projects all over Britain. It was instigated by Dr Andy Pearson, group managing director, who said: “SCIP support can take the form of funding, resources or time dedicated towards furthering a good cause that is in some way connected to the department or branch itself. The programme is open to any branch, office or department as long as the lead applicant is both a Star employee and personally connected to the cause, with registered charities and established educational organisations preferred targets of support.” To date Star has contributed over £10,000 to causes proposed by staff, not counting the time and material support also given. Examples include: °M acmillan Cancer Support: In September 2018, the Derby and London branches of Star Refrigeration held a coffee and cake morning complete with delicious baked goods, a raffle and prizes. The events raised £548 for Macmillan Cancer Support. °C hildren’s Hospices Across Scotland (CHAS): In support of the great care CHAS provides to families for children with lifeshortening conditions, a team of 15 staff from Star Refrigeration’s Thornliebank office signed up for a day of volunteering in May. This involved helping the Robin House Hospice with a day of gardening as part of their spring tidy-up activity.

°G lasgow Kiltwalk 2017: To commemorate their late father Billy Campbell, who had served as executive director of Star Refrigeration, his daughters undertook the Kiltwalk in 2017 and raised an incredible £7,350 for the British Heart Foundation. Star aided their efforts with a donation from the SCIP fund. J ° ohnstone Jets Youth Cycling Club: George Hamilton, a draughtsman in the Thornliebank design department, received a grant of £500 in 2017 to finance the training of two new coaches for the youth arm of his cycling club.

°D iverse Abilities: Operations training manager Dave Bartlett recently set himself the goal of running 12 half-marathons in as many months and, along with the help of his daughter Abigail and the support of SCIP, not only achieved his own target of finishing a half-marathon in less than two hours, but also raised £1,575 for the charity. In addition to the cases mentioned above, Star has also provided financial support, resources and staff time to a community theatre, a choir, a respite home, several junior sports clubs and other charities.

COOLAIR NIGHT RIDERS RAISE £2,000

Coolair Equipment colleagues Steve Valentine and Scott Lighfoot have raised more than £2,000 for charity on a 56-mile night bike ride. Regional director Steve and sales & design engineer Scott rode from Manchester to Blackpool in aid of the British Heart Foundation. Steve took on the fundraising challenge in memory of his dad, John, who died suddenly from a heart attack this year at the age of only 68. His fundraising appeal inspired Scott, who had undergone heart surgery, to join him. Having completed the 400-mile Agra to Jaipur Cycle Challenge in 2014 for Save the Children, Steve Valentine (left) and Scott Lightfoot celebrate at the finish line in Blackpool Steve found his latest ride equally demanding. He said: “The midnight start, hill climbs and freezing conditions, with the thermometer dropping to minus one degree centigrade, made this just as tough as my cycle ride across India. At the finish I was freezing cold and very tired but thrilled at having completed my first-ever cycle ride through the night. “When I started training I set myself a target of raising £600 and increasing awareness of heart disease amongst friends, families and customers. I was delighted that we raised so much money, which will be split between the British Heart Foundation and a local BHF store.” Contractor Coolair, which has offices in Manchester, Cannock and Kent, provides cooling and heating services to the retail, residential, commercial, education and hotel sectors.

Students claim Italy prize with Clivet

Susan Crombie (second left) and Mercedes DeQuer (fourth left) with fellow students and Graham Evans of Clivet (back left) and John Wincott from Fife College (back right)

College students Susan Crombie and Mercedes DeQuer have won a trip to Italy to visit the Clivet factory and learn more about heat pump systems. A competition to design the interior of a Fife College ecohouse challenged students to take the blank canvas of a basic house and design an interior that makes it into a home. The college has been working with Clivet on a project that will use the company’s ELFOPack heat pump systems to demonstrate and teach the theory and practice to students. The ecohouse, based at the College’s Stenton Campus, will also be used to demonstrate the system to possible users, builders, and local councils, so that they have a chance to see it in operation in a ‘real’ house.

Graham Evans, Clivet residential heat pump & light commercial business development manager, said: “Clivet Group UK are pleased to offer the students and staff the opportunity to understand the importance of renewable energy and in particular heating, cooling and air quality. It is our intention and responsibility to introduce these products to the next generation of installers and designers and what better place to start than Fife College, where the enthusiasm to learn and embrace the technology is clear and very welcome.” John Wincott, environmental services coordinator, said: “Fife College is delighted to be working with Clivet and using our ecohouse project to demonstrate this innovative use of heat pump technology. One of the biggest challenges facing the domestic heating marketing going forwards is our reliance on gas central heating. The Clivet system provides heating, cooling and hot water in one integrated unit, as well as filtering the air in the house to ensure that the home environment is as comfortable as possible. The system is ideally suited to new build properties where energy efficiency is part of the design. For our Interior design students to be involved in this project illustrates how wide-ranging the skills requirements are in modern building projects.”

Tom Woolston Star Refrigeration Trained by Eastleigh College

Employer Statement Tom Woolston joined Star Refrigeration in September 2017 as a 3rd year apprentice and has become a valuable member of the engineering team at Bristol, assisting with a variety of tasks from maintenance visits on large industrial ammonia refrigeration systems to reactive works on a variety of refrigeration systems. The engineers that Tom works with say he is a very good apprentice, able to carry out tasks assigned to him from maintenance logs on large ammonia systems and being able to identify faults through the interrogation of the logs taken. Every time I have observed Tom working on site I have been able to question him on the function and operation of system components and their integration into the large systems that Star Refrigeration typically work with.We are now exposing Tom to more complex tasks and sites. He is likely to progress to become an engineer by the end of the year and I fully expect him to rapidly rise through the Star grading system.

apprentice with knowledge and experience with larger systems he decided that he would work with another student with less experience in the practical sessions and show him how to strip down a C02 semi hermetic compressor. He also put himself up for the National SkillFRIDGE competition and got through to the regional finals. Having spoken to Tom’s employer, I wasn’t really surprised that they all hold him in such regard. From a lecturer’s point of view, Tom is a pleasure to teach as he really wants to learn. Watching young men like him moving into our industry fills me with pride, knowing that we are helping to produce good quality engineers for the future.
