PUMP HOUSE PROMOTIONS

PANASONIC VRF BREATHES NEW LIFE INTO WAREHOUSE

The conversion of a 19th Century Dublin warehouse into o�ce space for online fashion brand Zalando featured the installation of Panasonic’s 3-pipe ECOi MF2 AC solution by Crystal Air. FKM Group picked Panasonic for the project at Dublin’s Grand Canal Quay, which needed to be completed with minimal changes to the fabric of the building. Fresh air is delivered using Energy Recovery Ventilators (ERVs) in the roof space.

Bob Gallagher, operations director of FKM, said the decision was made because Panasonic provided “a highly e�cient integrated fresh air and AC system, coupled with the high standards of Crystal Air for the installation, which was especially important as all the components are visible.’’

The project resulted in Crystal Air obtaining the Special Recognition award in Panasonic’s PRO Awards.

The ERVs of the MF2 system recover 77% of the heat in the outgoing air with the air conditioning load being reduced by approximately 20%.

During the summer months the system allows for a purge during the night, allowing the cooler night air to be present for a fresh start to the day. The number of ERVs running at any one time can be reduced depending on the number of people occupying the space, for example, during lunch times.

Gallagher added: “We have been delighted with the level of support provided by both Panasonic and Crystal Air prior, during and after the project with our client Zalando being delighted with the end result.” www.aircon.panasonic.eu

June Richardson and Paul Greengrass have become directors of Nottinghambased condensate pump and ancillary product supplier Pump House, following the decision of company founder Craig Peebles to leave the business.

Dave Bass continues as Managing Director, with June promoted to Sales and Marketing Director responsible for all wholesale in the UK and Paul appointed to the new role of Business Development Director looking after export, OEM, new product development, engineering and new markets.

Craig left his position as Sales Director almost 17 years after founding the company (brie�y CP Pumps) with former colleague Paul Ludlow.

Pump House was acquired by US supplier DiversiTech in January 2016, formalising a partnership created through a joint venture established in 2006. There was a further change on 1 June this year when ownership of DiversiTech transferred to private equity �rm Permira after an acquisition deal was struck with previous equity owner, The Jordan Company. www.pumph.co.uk

CONDAIR JETSPRAY HUMIDIFIES AT FUJIFILM

A Condair JetSpray humidi�cation system is maintaining an ideal 40-60%RH (relative humidity) at the Fuji�lm Imaging and Innovation Centre in Bedford. It has been installed to provide the optimum atmospheric conditions for paper storage and printing.

The JetSpray consists of a control panel feeding compressed air and water to rows of self-cleaning spray nozzles mounted in the area to be humidi�ed. The compressed air atomises the water as it is released from the nozzle, creating a very �ne aerosol that rapidly evaporates. www.condair.co.uk

CHANGING WITH THE TIMES The IOR’s updated logo is designed to recognise a membership which now covers all parts of the RACHP sector.

T

he IOR says the recent change to its logo re�ects its commitment to members across the refrigeration, air conditioning and heat pump industries.

President Steve Gill said “Our membership is growing and is increasingly representative of all sectors, career stages and role types both in the UK and internationally. Individuals are joining the IOR as a result of our diverse programme of publications, events and educational offerings targeted to all. Members at all levels are keen to show their commitment to their profession by having the initials TMInstR, AMInstR, MInstR or FInstR after their name. Our new logo now demonstrates that the IOR represents all of the interests in the sector equally.”

The new logo aims to provide clarification for those new to the IOR, who may not realise that its technical guidance is equally relevant to air conditioning and heat pump applications.

Over time, the IOR membership has grown to reflect the wider industry as increasingly members identify as working across all RACHP sectors including, refrigeration, air conditioning and heat pumps. As the sector becomes more integrated, so the IOR says it is working to build links between the different applications, which are all based on

the same fundamental principles of mechanical cooling or heating transfer.

Central to this is the new Trailblazer Apprenticeship that the IOR has been promoting, which will focus on RACHP principles for engineering technicians.

The IOR service engineers section now also incorporates ACHPI (the IOR’s Air Conditioning and Heat Pump Institute) bringing together those who work in service, installation and maintenance roles across RACHP applications.

To raise awareness of the new logo and encourage involvement in this specialised professional engineering institution the IOR has developed a specific logo for companies to use on their website.

Members of the IOR can apply to use a “We support the IOR” logo on their

corporate website which links back to the IOR website to help visitors access the useful information about RACHP technologies available from the IOR technical library.

The new logo is the first stage in updating the IOR materials. A new website is under development, alongside redesigns of publications and report layouts to co-ordinate with the new logo and provide easier access to the technical publications, events and reports currently vailable.

The IOR also has an active Twitter, LinkedIn and Facebook following for those who want to keep up to date with developments as they happen. All of these social media feeds can be accessed from the current website at www.ior.org.uk

DOES R32 NEED NEW TOOLS?

R

32 systems are now available in the UK and, if the experience we’ve had with our MSZ-LN units is anything to go by, then they will become common very quickly – especially with businesses who want the stylish new designs, or corporations that want to demonstrate their adoption of aircon with a lower GWP.

Since R32 refrigerant was first announced, I’ve had engineers on my training courses wondering if this meant the added expenditure of new equipment to cope with the new R32 equipment.

If we are honest, the industry itself wasn’t as clear as it could have been at first.

You will of course need to ensure that any equipment you use includes an R32 compliant recovery unit, an R32 specific vacuum pump, a torque wrench set to the manufacturer’s recommendations on your flare joints and for pipework, stick to material that is R410A rated, as this also suitable for R32.

However, equipment manufacturers have been aware of this so many tools have been R32 compatible for several years. Start off for example by checking current equipment for the extra R32 indication on the gauge dial.

Get advice

In terms of transportation, most engineers are already used to carrying flammable gases so general good practice applies We know that R32 is mildly flammable and operates at higher pressures here as well. Reclaim cylinders, though, will have to be suitably than R410A, so is new equipment an absolute requirement? classified for use with R32.

So in conclusion to the question: Do I need to replace my All air conditioning engineers will already be operating under F-Gas procedures so will naturally be following best tools? The short answer is No, contractors can use many of practice which equally applies to R32. the same installation tools as are currently used for R410A. There are a couple of changes needed but if you Installation for R32 systems is similar to R410A units and there are already a wide range of tools and currently use modern, up-to-date equipment, this is equipment that are applicable to both systems. highly likely to be suitable.

The installation of pipework is identical for both It’s always worth talking directly to your wholesaler, first, flaring refrigerants so fl aring tools, vacuum pumps, scales and supplier, or even the manufacturer fi rst, though, to get fixing other fi xing tools can also be used for both installations. advice to make sure you get the equipment that suits both you and your business.

Charles McAlpine, right, with EasyAir colleague Andy Tull

harles McAlpine has joined distributor EasyAir Conditioning as Sales Director after leaving his position as Head of Air Conditioning and Heating with Samsung earlier this year.

He said: “The opportunity really excites me because EasyAir has a clear ambition to be the leading distributor in the UK. It is a well-established business with a great reputation built on providing technical solutions.

“I have been appointed to work with the Managing Director, Neal Gooding, and Directors Adrian Terrett and Andy Tull to grow the business and build on its unique foundations as a solutions and product supplier.

“I loved my time at Samsung. It’s a company with fantastic ambition and an amazing work ethic and I learnt a lot there. It just felt the right time of my life to make this change.’’

EasyAir was established in 2001 as a distributor of residential, commercial and industrial HVAC products. McAlpine said: “The company has been built on providing the best quality products with the highest level of engineering support. It is critical that our team is involved with projects and their design at a very early stage with the client and the mechanical consultant. But it is equally important that we work closely with the appointed contractors to ensure a smooth installation, commissioning and handover of the equipment.’’

THE VAMPS FRONTMAN BRAD

CHOOSES CARRIER FOR NEW BAR

B

rad Simpson, lead singer of pop rock band The Vamps, recently opened a stylish gin bar in the West Midlands and chose Carrier air conditioning to keep the customers comfortable.

Brad and his family were looking for an energy e�cient solution to heat and cool the new venture, Simpsons in Sutton Cold�eld, and picked Carrier to complement the chic surroundings.

MSE installed the equipment in partnership with Dean & Wood, their local wholesaler, who o�ered a full package of equipment and accessories.

Hayley Billson, Brand Manager for Dean & Wood, said: “It was obvious from the �rst site visit to Simpsons that no expense had been spared with regards to the interior design. Any air conditioning chosen had to unobtrusively blend into this lovely environment. The Carrier system’s package of slick looks, quiet operation and reliability, at a realistic price, made it the obvious choice.’’

The choice and siting of the Carrier equipment and ancillaries was an important consideration for MSE, who carried out both the design and installation. Installation time was reduced and site cleanliness was achieved

by MSE using the MaxiPro pipe jointing system. This eradicated the need for hot works in brazing or nitrogen OFN purging. Both Carrier wall mount systems supplied

by Dean & Wood have Wi-Fi

FUJITSU PROVIDING COMFORT WHERE IT MATTERS MOST Working in partnership to create the ideal environment for patients and medical staff at Prime Endoscopy Bristol.

P

Isambard Kingdom Brunel’s ship the SS Great Britain is close to the new building

rime Endoscopy Bristol, part of the InHealth Group, provide high-quality diagnostic endoscopy services in the community.

They recognise that patients prefer being treated in a community setting, avoiding hospital visits. Patients receive a quality, caring service at each stage of their journey because Prime Endoscopy Bristol are passionate about ensuring the patient experience is the best possible.

Creating the right environment for visiting patients and working medical staff alike is vital to their mission, so when it came to selecting a contractor for their new Harbourside Suite building project it was natural for them to turn to a trusted partner in Friargreen Construction Limited.

Friargreen Construction, based in Orpington, Kent, have a reputation for being a friendly, approachable construction company with a multidisciplinary ethos. This excellent reputation has been built upon their belief that the success of every project

is down to a successful working partnership between the client and contractor and they always strive to be the partner of choice to develop longstanding relationships. This approach has helped them work in the health care sector and with In Health Group (working in partnership with the NHS) for at least 10 years, with this new project at Bristol being a second endoscopy project involving Fujitsu air conditioning equipment.

The project houses equipment offering better clinical outcomes and improved comfort. It also contains training and conference facilities and additional consulting rooms, reducing waiting times and supporting growth in Bristol.

Fujitsu’s involvement concerned the selection of VRF VR II Heat Recovery equipment for two floors of the new building. Cassettes, medium static ducted in-ceiling fan coil units and wall mounted units were used throughout serving typically procedure rooms, treatment

rooms, recovery rooms, training room, clean areas, staff areas and the reception.

The design was by David Smith of Technical Support Associates (TSA) and the equipment selection was agreed with Toby Sparkes, Managing Director of Friargreen Construction. Toby had commissioned David as his consultant.

Impressed

TSA is a firm of mechanical and electrical consulting engineers, with vast experience in projects ranging from small houses to the complete infrastructural design of McDonald’s manufacturing factories.

Once the shell of the new building was erected, Friargreen became involved with their full turnkey operation and the images show how well the project has been completed. In Health Group entrusted Friargeen to deliver air conditioning, ventilation, electrical, plumbing and other building related tasks on budget and on time.

Specialist paint treatment to Fujitsu cassette fascia grilles

A fan coil unit and Fujitsu’s latest remote access central touch controller

Fujitsu equipment is delivering heat recovery to two floors as designed by the consultant as being entirely suitable and cost effective for the project. Toby Sparkes was particularly impressed with Fujitsu’s state of the art Central Touch Panel Controller with remote internet access as standard. This was said by Toby to be “a crucial piece of equipment for the company and the client, enabling the monitoring of the installation from afar and being able to manipulate the air conditioning settings if need be”. The adoption of the controller has resulted in the client insisting that this be a standard item for all such installations. Toby and the client received onsite training from James Richardson, Fujitsu Technical Supervisor, during Fujitsu’s commissioning of the equipment and it is planned to have a refresher training session at Fujitsu Head Office training facility.

Prime Endoscopy Bristol is located at Bristol Harbourside, a once derelict part of the historic city centre, which has been transformed from a brownfield site of former docks and industrial activity into elegant and enjoyable places to live, work and relax, full of green open spaces and waterside walks. The new building is set amongst many eco-rated new buildings serving the local community with

Isambard Kingdom Brunel’s ship the SS Great Britain a short distance away.

This location near the coast was a consideration for Fujitsu, who supplied specialist saline anti-corrosion treatment to the condensing unit coils. Additionally, a meeting room with a black ceiling also required specialist paint treatment to some cassette fascia grilles to the RAL colour of graphite black (appears as a darker shade of grey). The treatments have been acknowledged by the contractor and consultant to have been done to a very high standard.

The overall result has been a welldesigned and smoothly executed project that has most importantly delivered the high quality internal environment for those visiting and working in the building demanded by Prime Endoscopy Bristol.

Specialised

Human comfort and care is at the heart of this project and Fujitsu, working in partnership with Friargreen Construction and Technical Support Associates, have delivered an environment with attention to detail and clinical care.

Fujitsu’s VRF Business Development Manager Mark Derriman said: “It has been a pleasure working with Toby Sparkes of Friargreen and David Smith of TSA on this project. We have all worked together to enable Prime Endoscopy Bristol to do what they excel at, which is providing medical care in a comfortable environment.

Judging by the smiling expressions on the faces around the building, we have succeeded in providing a pleasant environment. It is a good example of Fujitsu supplying comfort when it matters.”

QUALITY COUNTS ON LG FACTORY TOUR

A

team from independent air conditioning distributor PACAIR visited the LG Electronics factories in South Korea and came away hugely impressed by the scale of the operation and levels of quality control.

The PACAIR group, along with top consultants, headed to LG’s main ‘Air Solutions’ factory at Changwon, on the south coast of the country.

A trip to Korea is a signi�cant commitment in terms of the distances involved and the time invested, but the PACAIR group were left in no doubt about the value of the visit.

One of the visitors said: “It is the sheer scale of the factory that impresses you �rst, along with the volume of products that they manufacture each and every day. For example, to travel from the Multi V 5 factories to the compressor factory within the same grounds, we had to go by coach!”

They were also blown away by the quality control. One member of the group said: “All manufacturers o�er quality control, but we were all amazed that after every process stage, a quality check is

carried out, as well as the �nal check at the end. If they are checked throughout every stage, then any imperfections can be picked up immediately and corrected there, where that part of the task has taken place. They know exactly what it is that needs looking at and rectifying.”

Checks

The quality checks include leak and pressure testing using helium gas. Helium is used, despite being relatively expensive, as it has more chance of detecting a leak than an alternative gas or liquid. Every product is fully tested to the highest standard as it leaves the factory. As a seal of guarantee, every product is labelled, inputted into the system and has the details of the employee that performed each check recorded. The same quality checks applied at the compressor factory, with the factory sta� all trained engineers.

LG also took the group to see a mixed Multi V hotel installation and a Multi V S high end residential installation. A large number of high-rise buildings in Korea have LG products installed. The approach to residential projects is quite di�erent to the UK, with an outdoor unit - Multi V S -

positioned for each apartment connected to various indoor units. The outdoor unit sits against the outside wall inside a cupboard with louvres. However, the hotel building visited had a similar set-up to a UK hotel, with plant on the roof. Many of the group commented on the large size of the hotel’s control room and how in Korea someone is on site to take care of the building at all times, unlike in the UK where it seems people rely on the hotel receptionist or concierge to monitor and check the system.

Nigel Palmer, Managing Director of PACAIR, said: “There is no question of the quality of LG Electronics air conditioning products; they are built to the highest standards and the factory is taking a real interest in the UK market, having developed products successfully already and for the future. Our Korean hosts were extremely friendly and rightly proud of their country, company and culture.

“We are looking forward to the launch of the Multi V S VRF heat recovery system coming to the UK in September, an industry �rst, a side discharge 6HP unit, and a product speci�cally developed for the heat recovery market.”

‘EVERYTHING SHOULD START AND FINISH WITH THE CUSTOMER’ David Dunn tells ACR Journal Editor David Todd why building loyalty is crucial to Toshiba’s ambitions for continued growth.

I

t’s hard to imagine David Dunn ever settling for second best, whether on the rugby pitch at Sandbach or driving the business as Director and general manager of Toshiba Air Conditioning and CIAT Ozonair.

The idea of selling a product not quite as good as it could be would be unacceptable.

Which is why the reaction to Toshiba’s latest three-pipe heat recovery VRF system has proved particularly satisfying.

Like its predecessor, the SHRMe has been picking up award nominations like a Hollywood veteran and the story behind its journey in the UK provides a snapshot of the way Dunn does business.

“Everything should start and �nish with the customer,’’ he said. “I started out in this business delivering air conditioning equipment and quickly realised that if you didn’t look after the customer, someone else would. If you do look after them, and give them the best you can, you take that loyalty with you.’’

That ethos has seen the development of a nine-strong UK technical team under Neil Wooldridge that provides a range of expertise to study every new product.

Maximise potential

Dunn recalls: “When the literature �rst came out on the SHRMe, we saw

O UT A N D A BO UT

“We asked the factory to test the SHRMe on 7/8 pipe and the feedback indicated a drop-off in performance that we felt was unacceptable. The figures were still better than other products but that wasn’t the issue; we knew the system could do more and were determined to maximise that potential.

Single range PRIDE IN INNOVATION

There is a genuine sense of pride when the conversation switches to the innovation of the UK operation, which has seen the in-house development of products including the Leak detection system, the recently-launched Smart Touch controller and the RBC-AHU1 kit, and a soon-to-be-launched air curtain.

Dunn said: “Ten years ago, a customer told me he had no space to put the AHU on a chiller and wanted to put it on an outdoor DX unit.

That led us to design and develop the AHU1 kit.

It’s manufactured here in the UK and sold to customers and manufacturers here as well as across Europe, the Middle East and Africa. good innovation and positives but also identified some areas that could cause challenges in the UK. “To maximise the performance, inch pipe was needed. This is used widely in most of Europe but not readily available here. In fact, we asked a leading pipe supplier how much inch pipe they sold and the answer was none! So we had to try and guess what might happen and thought that whoever was fitting the system would go for 7/8 pipe because it was the cheaper alternative.

“The factory was very accommodating and ultimately, a number of elements needed to be changed within the modules of products in the range. The figures were then as good as, if not better, than the original results.

“But those alterations meant that we had to get a UK-coded product with all the manuals, training CDs and websites needing to be changed. It was a big investment from the factory but we were able to offer the very best possible product to our customers. That’s what we are aiming for.’’

Toshiba bucked the trend in a difficult post-Brexit year for the UK in 2016 by showing strong growth. That progress has continued this year. “The reason we have grown is the customers we were dealing with 10 years ago are still with us, and we are attracting new ones.”

One-stop shop

“Of course we want to sell as much as we can but I always say, particularly to the younger staff, don’t go out to chase the order today. If something in the design is not perfect for the customer, we don’t try to sell it to them. They appreciate that and come to trust our judgement.’’

The same philosophy is being applied to CIAT UK, now sharing Toshiba Carrier’s

SPORTING LIFE

David Dunn’s dreams of a career in professional football were ended at the age of 17 when he shattered two vertebrae.

On the books of hometown club Newcastle United as a youngster, doctors told him he would never be able to play again and potentially unable to walk without the aid of a stick. But he was back on the pitch two years later, playing just below the Football League structure, and more recently took up rugby at the age of 39.

In 2005, as a result of issues connected to his back injury, David had major knee surgery and was confined to bed for eight weeks. He used the time to create a R22 replacement software tool, which is still being used by customers worldwide (in three languages) and recorded over 8,000 hits last year.

Leatherhead base following the purchase of CIAT Group by parent company UTC Climate, Controls & Security in 2015.

A comprehensive range of products can now be offered that cover the entire HVAC segment.

CIAT UK supplies chillers, air handling units, fan coils and heat pumps. Dunn said: “We have always been strong in splits and VRF but there is an opportunity to expand into chilled water and air movement technology. CIAT has some excellent products that complement our own range and we can now provide a one-stop shop for all the key HVAC building services technologies. Few companies can offer this breadth of equipment, plus the highest levels of technical back-up and design support.

“We are trying to make it as easy as possible for customers. As well as the technical side, we have worked hard to develop pre-sales and I am lucky to have the support of a strong and stable management team.’’

‘WHEN PEOPLE TRUST THE BRAND, THEY COME BACK’

“

David Todd spoke to the new man heading up Samsung’s heating and cooling operation in the UK.

P

erry Jackson has taken on the role of Head of Air Conditioning at Samsung and is putting trust at the heart of his vision for the future.

Jackson, who has joined from Mitsubishi Electric and will lead the UK B2B Heating and Cooling division, said: “I want to make sure that Samsung air conditioning is considered a trusted brand because when people trust you, they come back.’’

The business has been restructured to focus solely on air conditioning and heating products and Jackson believes that defines a clear path for the future.

“It was previously part of a bigger consumer division and that can sometimes dilute the message. What I would like is for us to be more targeted, more focused. The Samsung brand is very powerful and we need to make the best possible use of that.

“When I looked at Samsung from the outside, I didn’t think the picture was as clear as perhaps it could be. Because of the restructure it’s close to a startup situation and the energy that creates is what makes it exciting. The opportunity was just too good to pass up.

Culture

“Part of my job will be to educate and inform people about what Samsung has to offer and there is certainly room for growth. The market is changing in terms of what the customer requires and we need to react to that.

“I also want to grow personally and to do that I have to learn the culture of Samsung.’’

Jackson will head a team of around 20 in the UK and he said: “I want to spend time with the team and find out where they are with things, and also get out and see our partners and listen to what they have to say. Relationships are going to be a big part of the process.

“The challenge is to discover as much as

WHAT I WOULD LIKE IS FOR US TO BE MORE TARGETED, MORE FOCUSED. THE SAMSUNG BRAND IS VERY POWERFUL AND WE NEED TO MAKE THE BEST POSSIBLE USE OF THAT”

I can as quickly as I can and then point the business in the right direction.

“I have an engineering mindset and it is a case of deciding what order do I put the pieces together in?’’

Even before he joined the company, Jackson says he was impressed by the innovation of Samsung products, including the 360 Cassette and the ‘draught-free’ wall mounted unit.

He said: “The Samsung model has been mainly through distributors and that will continue, although we will be looking at different channels as well.

“Innovative products like the draughtfree unit can sometimes capture the imagination of customers and end users

more than installers, and that can be another way to help drive sales.’’

Jackson has more than 15 years of experience in the industry and joins Samsung after having worked in various roles from Specifications Director to General Manager - Branch Network at Mitsubishi Electric.

He is now responsible for all Samsung cooling, heating, ventilation and control products/solutions within the UK & Ireland and said: “Samsung is the leading brand operating in this space and I’m thrilled to be part of such a successful team. With my experience and range of skills I’m confident that I can help drive forward the continued success of the division.” www.samsung.com

WIND TOWERS A

WORLD CUP How traditional Middle East architecture is providing the inspiration for keeping fans and players cool at the Qatar 2022 FIFA World Cup.

E

ngineers from the University of Sheffield’s Energy 2050 research institute, in partnership with Qatar University, have developed an innovative system to keep fans and players cool at the Qatar 2022 FIFA World Cup.

Led by Dr Ben Hughes, the research team has developed a system to passively cool outdoor air and drive it through the stadium, providing cooling in the stands, concourse and at pitch level.

Of the design challenges faced, Dr Hughes said: “Normal air conditioning wouldn’t work. The temperature wouldn’t be stable and the huge flow of air would potentially interfere with the field of play.

WINNER One of the main challenges in holding the World Cup in Qatar is maintaining the thermal comfort of players and spectators. By using innovative cooling technology, we are able to reduce temperatures and the energy needed to meet carbon neutral commitments.”

The cooling technology that Dr Hughes refers to has its roots in traditional architecture of the Middle East region.

Wind towers were used for centuries to capture outdoor air and force it through a building, thereby creating a cooling effect

Dr Ben Hughes from the University of Sheffield

by the movement of air. Wind towers have been used in the stadium cooling design, to force air into underground chambers where the air temperature is lowered as it passes over heat recovery heat pipes filled with cold water. The heat from the air is transferred to the water in the pipes and ejected elsewhere. The cooled air is then pumped into the stadium, to provide relief to the players and spectators.

The Khalifa International Stadium recently reopened after extensive refurbishment and is set to host the World Athletics Championships in 2019 and World Cup matches in 2022.

SEPTEMBER 2017

Qatar.indd 26

14/08/2017 17:03

CO O LI N G

Heat pipes are sealed tubes partially filled with a fluid used to transfer heat between fluid streams at different temperatures. Heat is transferred due to pressure changes in the pipes, as fluid evaporates and condenses at either end of the heat pipe. This is a passive process as no energy input is required to transfer heat.

The idea for district cooling as a solution, where the air required for buildings is centrally cool and is then distributed to where it is required, is becoming more commonly accepted given the cost reduction and green credentials. A benefit of district cooling is that it uses recovered heat in a mixed mode to deliver a stable, comfortable indoor environment.

The ideas for the cooling of the stadiums were generated before the dates for the 2022 World Cup were moved from the summer to the winter due to fears about the effectiveness of the technology, its environmental impact and the fact nothing could be done to

reduce outside temperatures. However, Dr Hughes said the project could have delivered acceptable temperatures in venues even in June and July, although doing it in December is much easier.

“We’re aiming for a range of 24-26 degrees but could get it down to 21 degrees. And we think we can increase efficiency by up to 50%,” he said.

The research team had studied previous World Cups with high temperatures, such as the 1994 World Cup in the United States or the 2006 tournament in Germany, to work out the amount of stress players experienced.

As a result, Dr Hughes is confident heat

Testing the system to cool the stadium

in Qatar will not be the factor many have feared and is optimistic about the benefits of the technology for the region and the United Kingdom’s chances of tapping into the Qatari construction boom.

The first venue with this system is the Khalifa International Stadium, which was built in 1976 but reopened last month after extensive refurbishment and is set to host the World Athletics Championships in 2019 and World Cup matches in 2022.

This project was made possible by a National Priorities Research Program (NPRP) award from the Qatar National Research Fund, a member of the Qatar Foundation.

WEY-TEK HD: NOT JUST A SCALE Javac’s Technical Sales Manager Dave Kingston explains the benefits and features of the Javac Wey-TEK HD.

I

f we can prove the amount of refrigerant recovered, against the quantity of new used, then the material costings can be separated.

The rest is labour. For this we need traceable evidence showing how much refrigerant we have recovered from the customer’s system and present them with an immediate record at the time the work is undertaken.

The JAVAC Wey-TEK HD, with its robust construction and Bluetooth interface to an Android or iPhone, can record the total amount of refrigerant recovered in its job log facility. This information is now available to be viewed, edited/added to and emailed directly to the customer. With this information, our customer can better understand what we are doing with their asset and can see the refrigerant volumes against costs. This is especially important if we are opting to replace their R404a with one of the new lesser GWP drop-in refrigerants.

Many larger contract customers need to monitor new and waste materials for their various site registers. To have the facility to immediately log and email both recovered and charged refrigerants is a great advantage. This is a simple ergonomic and time-saving process that also cuts the amount of paperwork needed.

A nice addition to the Wey-TEK HD scale is the alarm facility. Provided connectivity is maintained within wireless

range (30ft), an alarm can be set so that when the charge nears completion it will send an alert, allowing the engineer to return to the job and finish the charge in the normal way. This is especially useful if the charge is taking a while to transfer from the cylinder into the system.

Alternatively, the low alarm features warns when the cylinder is also running low, allowing the engineers to change with minimal fuss.

The scale measures in pounds/ounces/ kilograms/grams, giving it the ability to charge large chiller systems; multi split VRV/VRF systems right down to small domestic fridges completing every job to the highest accuracy. Furthermore, a large durable weighing platform accommodates all jobs, from small 12kg cylinders, midi cylinders and large 65kg cylinder tanks.

The heavy duty, anti-skid rubber mat on the weighing platform gives extra stability to the bottle.

The scale is ipx4 rated, meaning the scale has passed various tests to ensure the scale is protected from water splashing with no harmful effect.

With its unique job log feature, adaptability, versatility and robustness, it is clear the Wey-TEK HD is much more than a simple scale. Its cutting edge technology allows the user to stay at the forefront of F-Gas regulations, while its job-log feature ensures efficiency.

ATTENTION TO DETAIL IN AMMONIA INSTALLATION

Stonegrove Refrigeration Services has delivered an ammonia installation ahead of schedule for global logistics company Kuehne + Nagel. David Todd visited the site just before handover.

M

ost elements of an industrial refrigeration installation are on a grand scale, but sometimes it is the little things that make the di�erence. Like Stonegrove’s decision to send a key member of the team to Belgium to personally check on progress when a delay threatened to impact a £1 million-plus project.

In fact, the ammonia installation at a regional distribution centre in Greenford, west London, for logistics giant Kuehne + Nagel was ultimately completed a week ahead of schedule.

Lloyd Hopkinson, Managing Director of principal contractor JJL Design and Build, said: “The end result is fantastic, de�nitely

one of the best cold room projects we have worked on. The design, installation and �nal product is something that everyone involved should be really proud of.’’

The new cold store has six High Bay coolers and the system features two GEA inverter drive single stage screw compressors.

The loading bays have three additional coolers, plus gas-powered dehumidi�ers to eliminate moisture and keep the cold store completely frost-free.

the design of the plant room; from a new heater mat and �oor to extensive leak detection systems.

The Installation took �ve months in total, with up to 20 Stonegrove sta� and sub-contractors on site, and the Practical Completion was a week ahead of schedule.

An unexpected delay to the delivery of an evaporative condenser could have been a potential problem but Senior Project Manager Dave Forman travelled to Belgium to check on progress of the order. The condenser arrived three weeks later than originally scheduled but the Stonegrove team was able to work around the delay and still keep the overall project on track.

Future-proof

Dave said: “When we realised the condenser was not going to be in place when we had planned, it made sense to go over to Belgium and make sure things were sorted out as quickly as possible.

“We did have a contingency plan in place to bring in a replacement condenser if necessary, but that was a worst-case situation. Sometimes, going and dealing with an issue in person can make all the

di�erence. We always want to do the best possible job as quickly and e�ciently as possible.

“We have had a great team on site and that is re�ected in the way the job has gone. We had a design meeting every fortnight where we let everyone know what was coming up in the days ahead and that always helps to �ag up potential issues and deal with them in advance.

“We delivered the project ahead of schedule and the customer made a point of telling us how pleased they were with the quality of work and attention to detail.’’

Commissioning Engineer Garry Dawson helped write all the software needed to control the plant and Stonegrove can access any part of the system remotely if a fault is detected.

Garry also oversaw Stonegrove’s rigorous testing and monitoring and said: “It’s a very energy-e�cient system. Looked after properly, it will last a long time. And by choosing ammonia, you are basically future-proo�ng your business.’’ www.stonegroverefrigeration.co.uk 01279 408690

WHY HUMIDITY CONTROL IS A JOB FOR THE EXPERTS Excessive moisture in the air can play havoc with industrial processes as well as human health. Terry Stevens-Smith, Director - National Accounts at Watkins Hire, keeps it fresh and dry in this round-up of the importance of effective humidity control in industry.

T

he amount of water vapour in the air (expressed as Relative Humidity) is a critical issue for many industrial processes as well as human comfort and wellbeing.

High humidity levels are associated with the growth of mould and pathogens, which can seriously affect safety in the manufacture, storage and transport of food, and has serious implications for many industrial processes that require tightly controlled climatic conditions.

Relative Humidity (RH) is defined as the amount of water vapour present in air expressed as a percentage of the amount needed for saturation at the same temperature. People are sensitive to high humidity because our bodies depend on evaporative cooling (enabled by perspiration) to stay cool. In industry, humidity levels can be critical, with millions of pounds of production and stock at stake.

When RH increases, condensation can occur on surfaces, resulting in problems with mould, corrosion and other moisturerelated issues. As well as leading to wood rot, this can present a serious safety hazard if emergency exits freeze up.

Watkins’ range of specialist dehumidifiers

Humidity control in food manufacture can be critical

Expensive shutdown

The good news is that, with the use of modern monitoring and humidity control systems, RH can be controlled to within very fine tolerances. Depending on the local climate and internal conditions, this may require humidification or dehumidification, or a combination of both to achieve the desired stable conditions.

There is a huge range of production and technical processes in factories, laboratories, hospitals, and other facilities that require specific RH levels to be maintained within specified tolerances.

In pharmaceutical manufacture, for example, RH can be critical to product safety and quality. The amount of moisture in the air affects powders and tablets, and their tendency to clump or crumble. Unacceptable moisture content levels can lead to an untimely and expensive shutdown in production.

The power industry takes humidity levels very seriously due to the risk of corrosion during planned or unplanned shutdowns. Dehumidified air is injected into areas around critical components such as turbines, boilers, and reactors

to safeguard against damage. In some instances, low dew point air (-25°C) has to be delivered and maintained during such plant stoppages.

In data centres, RH levels may be carefully monitored and controlled in order to minimise the risk of static discharges, which can damage sensitive computer chips and related circuitry. The impact of uncontrolled static in sensitive facilities, perhaps involved in national defence or critical financial infrastructure, could be incalculable.

Key role

Even in the relative rough and tumble of the construction industry, humidity control plays a key role, due to the risk of mould growth that can despoil buildings, with the consequent effects on human health and rental value.

Once mould becomes established, the cost of remedial treatment can be high, and resultant delays in project completion can lead to retentions and penalties for overruns. In addition, controlling humidity and temperature may be required during climate-sensitive fit-outs, such as the installation of expensive timber.

In the marine and offshore sector, blast cleaning for tanks and ships and surface preparation for specialist coatings are sensitive to air-borne moisture. The integrity and longevity of treatments may depend on the stability of the environment in which the work is carried out. The lifespan of costly coatings can be extended by ensuring specified temperature and humidity targets are maintained during application (see case study).

Food production is another obvious sector where temperature and humidity levels can be critical. In addition to the safety and hygiene issues, the productivity of specialist plant, such as spiral freezers, can be maximised through the introduction of low dew-point air, to minimise frost and ice build-up in cold store areas.

Comprehensive support

Over the years, my own company has provided humidity and temperature control solutions for all of these sectors, and many more diverse applications besides.

Our specialist humidity control team provides comprehensive support for building owners and industrial end users, based on access to one of the widest ranges of humidity control equipment, available for hire from our network across the UK and Ireland.

Equipment includes both refrigerant and desiccant-based dehumidifiers, capable of treating between100m3 to 8000m3 of air per hour, and removing between 29ltr/24hr (based on 60per cent RH at 20degC) and 71 litres/hr (based upon 80percent RH at 20°C).

As part of a strategic growth plan in this important and growing sector of environmental control, we recently invested in a new fleet of state-of-the-art desiccant dehumidifiers, based on the KwikDRY system.

Equipment is now hard at work across the country in factories, sports halls, industrial buildings, restoration projects following flood or water leakage, storage facilities, food processing, and floor laying on construction sites.

CASE STUDY: Watkins helps deliver specialist marine refurbishment project in dry dock

W

atkins’ dedicated dehumidi�cation team recently designed a bespoke ventilation and dehumidi�cation solution to meet the requirements of a specialist maritime application.

A vessel in dry dock on an MOD site was undergoing a major refurbishment, and part of the work involved repairing and re-painting the hull, above and below the water-line.

Watkins Hire supplied a temporary package of dehumidifiers and ventilation equipment to create and maintain the required conditions for the repainting works to be undertaken.

The company’s specialists visited the site to assess the requirements, and recommended a tailored solution consisting of a combination of KwikVENT 1000, KwikVENT 8000 and KwikDRY 8000 units, with related ducting, mains electrical cabling and a distribution package.

The ventilation system comprised fans and ducting, which were used to remove paint fumes from the vessel and introduce fresh air to the areas needed for personnel working nearby.

The dehumidification plant successfully maintained the required Relative Humidity in the chambers within the vessel’s hull, allowing the critical paint application to be completed successfully.

All equipment provided for the project was supplied as new. Similar refurbishment projects are expected to be repeated on two further vessels during 2017.

Kenfield Doors Managing Director Tom Moloney explains how energysaving doors can make a big difference to efficiencies in supermarkets and in food processing.

THE SCIENCE OF SECONDARY DOORS

I

nsulated energy-saving secondary doors can play a key role in increasing margins in the food processing and the supermarket sectors. With money tight and end users looking for high-end savings, storing products in an energyefficient environment will make a considerable difference to the bottom line of any supermarket or food processing operation.

It is hard to believe that in some cold stores and freezers, doors are left open to allow ease of movement for staff.

These can be heavy, ill-fitting and a hazard to employees. This leads to cooling systems having to work harder and results in increased energy costs which are ultimately passed on to the customer.

Kenfield has been working on a new generation of insulated, flexible, energyefficient secondary doors over many years. In 2013 we began trialling the Kenfield K750 Insulated Energy Door with Sainsbury’s and Tesco and the results were impressive with proven savings in energy costs, workplace efficiencies, ease of use, maintenance and longer life.

Optimum level

Our uniquely designed and patented K750 door was launched that year and since then thousands have been fitted in cold stores, chillers and freezers across the UK with other supermarket majors including Asda, Morrisons, Marks & Spencer and Aldi joining our list of customers.

Often when building a cold store or freezer the main cooling system is at the forefront of the mind of the refrigeration installer or designer. But secondary doors can make a big difference to the overall energy bill and working environment and they should be included as part of the plans from the start.

Without secondary doors, the outer doors are vulnerable and poor maintenance, and the fact that they are heavy and awkward to slide, will lead to employees leaving them open.

But the outer door can stay open if secondary doors are fitted. These light, PVC covered doors – with no sharp surfaces – can be pushed through with ease by staff. They will automatically close behind them, won’t hurt them if

they brush through and will ensure that the temperature inside the freezer or cold store is maintained at an optimum level.

Prevent snowing

Fitting secondary doors also saves a lot of time in the working environment as staff will not have to open and close the outer doors when they pass through what could be hundreds of times a day. The knock-on effect is that it will take fewer people or less time to unload a lorry or restock the shelves.

Outer doors also have alarm systems to monitor their use remotely and these alert the management when they are left open. Once secondary doors have been fitted and the temperature inside the cool area is maintained at a constant level, the alarms will sound on a less frequent basis.

Secondary doors can also help prevent snowing. This occurs when you get a buildup of warm air in a cold room which leads to condensation on the ceiling which then drops down as snow. In turn this can lead to icing on the floor which can cause accidents for staff and can be particularly dangerous if heavy trolleys are being employed.

Flexible panels on our energy efficient secondary doors mean that they are versatile enough to bend around corners and this lightness and ease of use gives them the edge in the cooling environment over other alternatives. Secondary doors don’t tangle or attach themselves to passing trolleys containing foodstuffs. The K750 has two layers of insulation – with an air gap in between – which places it in a different league when it comes to keeping the cool air in and the warm air out.

Health & Safety Executive why a door was at fault at the time of an accident. With food the main product in a cold room or freezer, hygiene is a key factor to consider.

Easy to maintain wipe-clean secondary doors ensure the perfect environment for foodstuffs to pass through.

Staff are also often worried about being stuck behind a heavy door or locked inside a cold room or freezer but because secondary doors are light and easy to use this removes any of these anxieties.

Secondary doors pay for themselves very quickly. I can recall one occasion when

we tested a door it was found to be 16°C on the outside of the room and -22°C on the inside where the food was stored.

Customers have reported savings in the region of 20 to 25% on their energy bills and in this respect the figures speak for themselves. Away from the UK, customers in Europe also like what we do and I believe that the future is bright for secondary doors in the cooling industry. +44 (0) 121 451 3051 sales@kenfield.com www.kenfield.com

Low maintenance

Secondary doors have to be robust as they are in constant use. Traffic to and from the chiller or freezer in a major supermarket or warehouse can be heavy with people and trolleys passing through at a rapid rate. Knocks and bangs are a normal part of this so the doors have to be built of materials that can withstand this wear and tear. Our doors are manufactured to withstand this and have very low maintenance.

Health and safety is another important issue to consider. A door propped open can present all sorts of trip hazards and no employer wants to have to explain to the

SUSTAINABLE

SHOPPING Marta San Román, marketing leader refrigerants, Honeywell Fluorine Products, on how Honeywell has been helping Tesco to reduce its carbon footprint.

ack in November 2015, members of the Tesco executive team attended the UN Climate Change conference in Paris (COP21). It was there that they restated the company’s support for the many actions required to meet long-term climate targets.

In 2017, Tesco announced plans to switch its entire operations to 100 per cent renewable energy, and to reduce food waste with new re-sealable salad bags. These initiatives have all been very visible to consumers, but even more is happening behind the scenes.

Tesco’s climate commitments cover three main areas: engagement with policy makers on the low-carbon economy, investment in energy efficiencies and renewable energy sources, and investment in advanced refrigeration systems to drive carbon reduction.

SEPTEMBER 2017

Change needed

It’s in the latter area that Honeywell has been helping Tesco to reduce its carbon footprint. By moving to Honeywell’s Solstice N40 in about 1,200 stores, the CO2-eq tonnage relating to service leaks can be reduced by 40 per cent.

One major cause of supermarket carbon emissions is their choice of refrigerant. R404A has a very high global warming potential (GWP) of 3922, and accounted for 99 per cent of Tesco’s CO2equivalent refrigeration carbon footprint from direct emissions. To meet their sustainability commitments, it was clear Tesco needed a change.

Under the new strategy, any new store that Tesco opens will use the lowest GWP refrigerants available. Equipment that will last beyond 2022 will be retro�tted with a lower GWP refrigerant, while equipment older than 10 years will be sustained until its replacement between 2016 and 2022.

To initiate the conversion, Tesco launched a review of its current refrigerant system to determine how changes could be made in the most cost-e�ective manner. The supermarket organised a seminar for the UK and world supply chain base, to set clear goals across the business and ensure cooperation during the conversion process. Tesco also created an extensive database of existing assets, making it possible to track the age of equipment.

Product quality

After assessing the alternative refrigerants on the market, Tesco chose to trial two refrigerants in UK stores: R448A and R-449A. These �eld tests took place in four large format stores and four convenience stores, located in both the north and south of the UK to cover the varying ambient conditions.

The refrigerants were measured against product quality, system temperature performance, system energy consumption, and refrigerant leakage.

R448A, otherwise known as Honeywell’s Solstice N40, had considerable advantages as an alternative refrigerant.

It has a GWP on 1,387 (1,273 according to the �fth revision), making it the lowest-GWP, non-�ammable refrigerant

Brian Frankland, Tesco

commercially available today that can be used to retro�t existing systems as it acts as a near drop-in replacement for R404A, rather than requiring substantial investment in a whole new refrigeration system.

Following the successful trials, Tesco selected the R448A option as the cornerstone of their new global sustainability strategy to reduce refrigeration emissions.

The program began in January and by the end of March more than 50 stores had been successfully converted to R448A. More than 200 stores have now been retro�tted.

39

The success of the conversion project required a close collaboration between Honeywell and its UK partners, to ensure there was no disruption to Tesco stores and services. A-Gas, a major distributor of Honeywell refrigerants for the UK, provides a reclaim and testing facility, while Climate Center provides national delivery and collection of new and reclaimed refrigerants. Carter Synergy and Space Engineering, meanwhile, provides the expertise for the actual conversions in each store.

Every store has di�erent requirements that impact the time required for each R448A retro�t. Store size, condition and type of equipment, and whether there is a need to repair or replace parts of the circuit, can all impact the time taken.

Reduced consumption Throughout the process, Honeywell provided Tesco with technical support to minimize retro�t time and disruption to stores. The actual upgrade takes place overnight, so customers experience no disruption.

“R448A allows us to not only improve our environmental commitment though a much lower GWP, but has also helped to substantially reduce our refrigeration energy consumption,” added Brian Frankland, Tesco. “The logistics involved in the recovery, reclaim and re-use of the existing R404A has worked well.”

Tesco is just one of the many supermarkets that are turning to lower-GWP refrigerants to meet sustainability commitments. More than 2,000 supermarket installations were completed with R448A by the end of 2016, and more and more supermarket companies are using R448A in large-scale store conversions to help meet their energy e�ciency goals.

It is in the interest of all large R&AC installations to accelerate the conversion to more environmentally preferable refrigerants such as R448A. These refrigerants are available today and they avoid the inevitable legacy product scarcity that will come from F-gas phase down. Taking the initiative today means retailers of all sizes can decrease their carbon footprint, while simultaneously increasing energy e�ciency and the bottom line.

HIDDEN STEP HEIGHTENS PHASE-DOWN IMPLICATIONS

“

Graeme Fox of REFCOM and the BESA says a business-as-usual approach is no longer sustainable.

A

THERE CAN BE NO MORE BURYING OF HEADS IN SAND AND HOPING THIS WILL GO AWAY – IT WON’T”

s we approach the end of the second step of the phasedown of HFCs embedded in the EU F-Gas Regulation, it is important to look at the implications and, perhaps more importantly, the hidden step that kicked in at the start of this year and has already forced prices of higher GWP gases up and is shaping the market for the next 10-15 years.

The phase-down aspect of the F-Gas

revision has been much talked about and the message is starting to get through to contractors, but there are still thousands of clients using equipment that will very soon become obsolete due to the lack of availability of gas, at best, or the ban on use of the gas in many cases.

Our Technical Bulletin TB004 Phase Down of Refrigerants, published in February 2016 and available for download from the website or by contacting

REFCOM, was the first of a series of useful guides and explanations of what is meant by aspects of the regulations and how it will affect members. It spelt out the sharp drop from 2018 where we lose 37% of the gas allowed to be placed on the market compared to the baseline 2014/15 level, and the fact that it’s now based on GWP (expressed in equivalent tonnes of CO2) of the gas rather than physical quantities, to reflect the more significant implications of leakage of high GWP gas compared to lower GWP gas.

Potential consequences

The consequences of this have been well documented in recent months by REFCOM and others. The sharp drop in CO2 tonnes equivalent terms means that higher GWP gases like R404A will become scarce even before they become banned for use as virgin refrigerants, meaning the price of that gas will continue to rise rapidly over the coming months, as it has been doing since 2015. That has such real and potentially severe consequences for contractors and their clients that it is essential these are addressed sooner rather than later.

REFCOM has been working closely with gas manufacturers to establish

*Source: European Commission guidance on best alternatives as drop-ins and alternative solutions to the problem.

Many of the alternatives bring with them a whole new set of considerations for field technicians and designers – particularly where the gas is now flammable. New EN378 design considerations and occupancy levels all need to be considered and REFCOM is keeping constantly on top of developments and delivering guidance where required.

Of more immediate concern for contractors are the rapid price rises of HFC gases, not just R404A but also R410A and other commonly used gases that, although not threatened with service or use bans in the near future, are nevertheless seeing month-on-month price rises. Questions have arisen surrounding why this has already occurred if the next step isn’t until the end of the year and some unfair accusations have been placed upon the distributors and gas manufacturers.

TB004 spelt out this ‘hidden step’ and the implications to contractors. The crux of the problem is that, although the overall total quota amount hasn’t changed between 2016 and 2017 – in other words the total amount of HFCs placed on the single market in the EU has remained the same for these two years – the amount effectively dropped by an additional 11% from the 2016 amount because

gas imported into the EU in pre-charged split systems has now become part of that quota level since 1 January this year, whereas before it was only bulk supplies of gas in bottles that was counted.

Supply and demand

This restriction on the total amount of gas being placed on the market not already accounted for in split systems has been felt most keenly in the non-“pre-charged” sector, in other words the commercial refrigeration sector. Quota holders have far less quota available to them for placing on the market high GWP gases which take up big chunks of their quota, so many have already said they will be stopping the supply of gases like R404A from the year end and they are already placing less on the market this year. The laws of economics – supply and demand – bear out that the shortage of gas placed on the market will result in prices rising, as we have seen in recent months.

The bottom line is that a business-asusual approach is no longer sustainable.

Contractors need to start the conversation with their clients now if they haven’t already. There can be no more burying of heads in sand and hoping this will go away – it won’t.

Brexit will not affect this pattern either – regardless of

the decision on how the UK and the EU collectively divide up the quota for the market, the market as a whole will continue the phase down approach and global moves are all in line with this as well. High GWP prices will continue to rise steeply from here on in, and the sooner you and your clients get ready, the smoother the transition for all. www.refcom.org.uk

SUPPLY AND DEMAND

“

A-Gas Managing Director John Ormerod explains why rises in the cost of refrigerants are happening and how they are changing the market.

John Ormerod

T

he price of refrigerants has been rising steeply this summer as the F-Gas Regulations tighten their grip on an industry adapting to change. The higher GWP refrigerants are taking a hit as the availability of some gases is reduced and engineers and end users make the switch to low GWP alternatives.

According to Okorecherche, the research group used by the European Commission to monitor refrigerant prices under the F-Gas Regulations, the producer selling price of the industry’s go-to gas R404A – the highest GWP option – has increased by as much as 500% in the last three years.

This has been reflected by large price increases for customers in the UK. The figures also reveal that the producer selling prices of R134a, a gas commonly used in air conditioning, have risen by more than 200%. The prices of other popular HFC-based refrigerants have also risen significantly.

Broadly speaking I expect these rises to continue. Supply and demand is coming into play and those who are desperate to get their hands on high

THE PRODUCER SELLING PRICE OF THE INDUSTRY IS GO-TO GAS R404A HAS INCREASED BY AS MUCH AS 500% IN THE LAST THREE YEARS”

GWP gases are willing to pay more.

What we have started to see is the price of refrigerants starting to align with the GWP rating of the product. That’s because the overall quota system is capped on a CO2 equivalent which ensures that the GWP value comes into play. R404A, for instance, has a GWP (or CO2 equivalent) of approximately three times that of newer generation refrigerants for the same application.

As the market availability is capped by CO2 equivalent, then under normal economic theory we could expect to see R404A reach three times the price of the newer generation products – perhaps more if shortages occur.

Balance

For a long time the price of R404A was not markedly any different to that of the lower GWP alternatives but towards the end of last year, and certainly this year, that changed significantly. The price of R404A is reflecting a shift in market patterns as the new low GWP refrigerants come to the fore.

We have not seen shortages yet but it is evident that the supply and demand balance is much tighter this year. There is little surplus refrigerant on the market which you would ordinarily expect would keep prices suppressed. This year may not have been a step down year quota wise but imports of pre-charged equipment have started to come under

the regulations and this has had an influence on supply.

Pricing will more and more be driven by market behaviour and I predict that the newer generation low GWP gases will become more cost effective in comparison to the older generation refrigerants. This is another factor which will focus the minds of contractors and end users, and in turn drive people towards converting to low GWP gases.

Frequent spells of hot weather have provided the industry with a tonic this summer. Hard-working refrigeration cabinets in supermarkets and stores have had to up their game to handle the rising temperatures. Much-needed air conditioning systems in commercial buildings have also been working hard as temperatures have topped the 30°C mark. This means that engineers have also been working overtime to keep the systems up and running.

Opportunity

I have seen pictures of supermarket cases out of commission in instances where the higher temperatures have caught the end user on the hop. Sales wise we have had some very good weeks when the weather was warm but I shall wait until we are into the autumn before passing judgment on whether we have had a good summer for the industry.

In this respect a more effective maintenance regime will ensure that these breakdowns do not happen in future but don’t forget these windows do provide the installer with an opportunity to review refrigerant use

and make the switch to a low GWP alternative if necessary.

Brexit and how it will affect our industry is still very much a case of wait and see. How we leave the European regulatory framework and impose our own UK regulation regime is still up in the air. I suspect that the F-Gas Regulations will continue to loom large in our lives and the only question that will have to be answered is how the quota system will be managed away from the European Commission. It will be a number of months before we start to see what will emerge from the negotiations on this.

Within the European framework some countries like those in Scandinavia have chosen to go beyond the F-Gas Regulations and impose more stringent step downs but generally speaking most across Europe have remained in line with each other. I do not see this changing.

FANTASTIC RECEPTION FOR RAPID RECOVERY

The launch of A-Gas Rapid Recovery was the highlight of our summer in Bristol. This new, nationwide service provides an outsourced refrigerant recovery to hard-pushed contractors.

We bought the company last year in the US after we recognised that by offering a similar service in the UK it could make a big difference to the way the industry operates.

At the launch, the speed of the system surprised many people – ten

times faster than the alternatives on the market. The reaction from customers, business partners and the media was very positive. We received a fantastic reception from contractors and they can see that it will have tremendous value in how they operate – saving them time and money.

MAKING THE MOST OF

FREE COOLING

Brendan Leonard, Managing Director at STULZ UK, explains the benefits of free cooling and how it can proactively create efficiency and have a positive impact upon data centre optimisation.

D

ata centre cooling is a continually evolving science due to the amount of equipment variations possible and the number of options in terms of facility design and operation.

There is now a plethora of cooling methodologies, from hot aisle to cold aisle, row containment, rack containment and water cooling but one of the most e�ective – both in terms of cost and application – is free cooling.

Power ranger

Data centres consume almost as much energy for non-computing resources as they do in powering their servers. That is why Power Usage Effectiveness (PUE) has become such a prevalent industry metric – the closer it is to 1.0 then the better the facility is doing in managing its use of noncomputing energy – and free cooling can help lower this figure.

So what do we mean by the term free cooling? Gartner defines it as ‘any technique used to reduce the energy consumed by cooling systems or the time that the cooling units run by using the outside temperature of air or water to cool the data centre or other facilities’. Free cooling helps save energy and for most of the time UK ambient air temperature is colder than that required in the data centre – so a simple ventilation system can maintain compliant conditions.

Temperature gauge

Before looking at free cooling in greater depth, it is worth noting that there are various measurable temperatures present in a data centre including supply air, return air, room air, cold aisle, and server inlet and exit temperatures.

Brendan Leonard

Server inlet temperature and server exit temperature are well known to have a significant effect on the efficiency of any cooling system and the higher the former, the more efficient a cooling system can become.

Just as importantly, attitudes towards data centre temperatures have changed drastically over the last 20 years or so. Previously, the computer room air conditioner (CRAC) return air temperature was the main control parameter and was set to 22-24°C. This resulted in unnecessarily low supply air temperatures in a range of 12°C. Today, the best practice is very different. In a modern data centre, supply air temperature is the main control parameter and it is typically set between 18°C and 27°C, as recommended by ASHRAE TC9.9. This has resulted in return air temperatures to the cooling equipment of 25-40°C.

Different strokes

Although the concept behind free cooling is relatively straightforward, there are a number of ways to go about achieving it.

₀ Direct free cooling With direct free cooling, filtered outside air is fed directly into the data centre if the CRAC system determines that it is at the right temperature. This means that the compressors do not have to operate as often, saving electrical energy.

However, in urban areas air quality might not be good enough and is often full of particles, which can be very hostile to modern IT equipment. Therefore, direct free cooling should only be used where filtering can control the quality of outdoor air. Also, if the outdoor air is too cold, a certain proportion of warm air from the data centre must be mixed in with it to supply controlled, tempered air to the IT equipment.

Humidification also has to be controlled and methods to humidify or dehumidify air can also be very expensive and complex, with large ductwork systems often required. In addition, large openings in the building fabric are needed to bring in the outdoor air, plus an equally large ductwork system and fabric opening for the exhaust air. These openings and ductwork bring a security risk to the data centre that has to be considered and in the event of an external situation such as a fire, the system must have the ability to operate independently of the air inlet. ₀ Indirect free cooling With indirect free cooling, no outside air enters the data centre and CRAC systems can be configured to suit requirements.

However, indirect free cooling is theoretically less efficient than direct free cooling, as at least one heat transfer must always take place between the air in the data centre and the outdoor air.

Single stage indirect free cooling is based upon an air/water heat exchanger

placed on the hot water return of the chiller. Outside air is blown across the heat exchange and helps removes the heat before it gets to the chiller. Therefore, with a return water temperature of 20°C, if the outside temperature is 19°C or less, it starts reducing the activity of the chiller and reduces running costs.

Two stage indirect free cooling systems have a considerably smaller footprint than their single stage counterparts, but are less efficient, as they function with two heat transfers. In the first heat exchanger, the heat from the air in the data centre is transferred to a liquid, normally glycol. This is then pumped to the outside in relatively small pipes, where heat from the data centre is rejected to the outdoor air via a second heat exchanger. ₀ Indirect dynamic free cooling To further improve the efficiency of indirect free cooling, dynamic technology controls the mode in accordance with the current heat load in the data centre, and so increases the time in free cooling mode. Moreover, it has another operating mode – extended free cooling – that further lengthens the operational time and drastically reduces operating costs by cutting energy intensive compressor cooling to a minimum.

FREE COOLING HELPS SAVE ENERGY AND FOR MOST OF THE TIME UK AMBIENT AIR TEMPERATURE IS COLDER THAN THAT REQUIRED IN THE DATA CENTRE”

Liquid asset

Air contains a certain amount of water and the total amount depends on the air temperature and barometric pressure. As water absorbs into the air, an adiabatic process takes place – this means the temperature of the air decreases, while the energy content of the air remains unchanged.

By using adiabatic assistance in direct free cooling systems the air that enters the data centre is cooled before entering.

Indirect free cooling and adiabatic assistance is more conducive however, as the adiabatically assisted outdoor air never enters the data centre. In single stage indirect free cooling systems, adiabatic assistance reduces the temperature of the outdoor air entering the air/air heat exchanger and reduces the amount of mechanical cooling required to satisfy the supply air temperature to the IT equipment. In

two-stage indirect free cooling systems, the warm outdoor air can be cooled by adiabatic assistance before entering the dry cooler to either increase the hours of usable free cooling, or extend the mixed mode at the upper limit to reduce the use of mechanical cooling.

Last word

As the density of installed equipment in the data centre has risen, so too has the amount of heat generated. While being able to fit more kit into a smaller space is generally considered a good thing, the need to control temperature has led to the growing use of free cooling.

It should be remembered that no free cooling system is perfect though, and all have limitations. It is therefore important to evaluate what kind of free cooling is best suited to the application on a case-by-case basis. www.stulz.co.uk

THERE TO HELP, NOT HINDER Chris Wellfair, Projects Director at data centre design and build company Secure I.T. Environments, looks at the importance of regular system inspections.

I

f you are responsible for the air conditioning systems in your business, then you should already be familiar with the TM44 requirements to undertake regular inspections of the installation, to ensure that it is performing correctly and efficiently. It is not just a legal requirement, but simply good practice that can help identify maintenance issues, cost saving opportunities, reduce energy consumption and the carbon footprint of your business.

Often data centres, particularly if they are modular or in their own building can fall under the remit of the IT department for air conditioning, rather than Facilities.

Whilst we do not undertake inspections, we have certainly spoken with companies that were not clear on where the responsibility lay for looking after those specific systems. Whilst in most cases systems the estate was being fully

inspected, you certainly don’t want to find yourself in a situation where an Air Handling Unit (AHU) gets missed, as you will be fined up to £500 for a combination of failing to get an inspection completed, and not being able to produce a current certificate for all AHUs. The process of getting an inspection completed is not difficult, but because of the way companies often have their estate spread across sites it is possible for units to get missed if adequate asset lists are not maintained. Ignorance of the requirements will not be an excuse as far as the law is concerned of course, but if you already have maintenance contracts in place then this should be covered under that agreement. It is important to check though!

Responsibility

Inspections must be carried out by an accredited air conditioning energy assessor who is a current member of an accreditation scheme. Only

inspection reports which have been produced and lodged by accredited air conditioning energy assessors qualify as valid reports.

So, who needs a TM44 inspection?

Basically, every company that has responsibility for its own AC implementation that is rated at 12kW or higher – companies that are a building tenant should be covered by the building owner.

TM44 emerged following the appearance of the Energy Performance of Buildings Directive by the European Parliament in January 2003. Essentially it required all member states to introduce laws that would ensure that energy consumption and use where legislated for to ensure good practices. TM44 is published by CIBSE for those that want familiarise themselves more closely with the work of the working party that produced it.

All air conditioning systems with an effective rated output of more than 12kw must be regularly reviewed by an accredited

SEPTEMBER 2017

DATA C E N T R E C O O L I N G

ACI Inspector – inspections must be no more than �ve years apart. All air conditioning systems are now covered by TM44, but there were speci�c quali�cation dates depending on ‘into service’ date of your AHUs. The regulations require the �rst inspection of air conditioning systems to be carried out as follows: ₀ for all systems �rst put into service on or after 1 January 2008, the �rst inspection must have taken place within �ve years of the date when the system was �rst put into service ₀ for all other air conditioning systems, where the e�ective rated output is more than 250kW the �rst inspection must have taken place by 4 January 2009 ₀ for all other air conditioning systems, where the e�ective rated output is more than 12kW the �rst inspection must have taken place by 4 January 2011.

The inspection

The inspection itself is a straightforward process. The inspector will need access to each AHU, as well as associated hardware and control panels. They’ll conduct a visual inspection of each piece of equipment, as well as measure the e�ciency of the equipment. This information, along with any identi�ed

faults and suggestions for improvements to the e�ciency of the system will be included in the report provided. Critically, they will also provide a certi�cate and guidance on how to review the use of air conditioning within your business. Acted on, this guidance will lower long term costs, reduce environmental impact and improve energy e�ciency. Providing this report is a requirement on inspectors, so make sure you get it.

Choosing an inspection supplier

We’ve talked about the importance of the legislation and what an inspection involves, but how do you choose an assessor? There are four main considerations when you are choosing an assessor which we always give to our own data centre clients: ₀ Firstly, only appoint companies that are an ‘Accredited ACI Assessor’. Only inspection reports which have been produced and lodged by accredited air conditioning energy assessors are valid reports under the TM44 requirements ₀ We advise clients to choose a national company. It generally means that have better resources, are able to conduct assessments at short notice, and o�er a greater level of cover depending on the support you are looking for from them

47

₀ Inspection charges are usually de�ned on cost per AHU, so be sure to get an estimate from the company before you appoint them. This should be transparent and clearly the show inspection cost of each piece of the estate. Do not settle for a quote that is not broken down ₀ Have a clear understanding of how the appointed assessors need to conduct the tests, the overall time required and downtime that may be needed. In the case of data centres, or temperature sensitive locations, it be appropriate to schedule assessments to take place outside busy o�ce hours or times when the data centre will be operating under peak conditions.

It is easy for us all to get frustrated by red tape, but the truth is that the TM44 inspection regime can have a profound impact on the performance and e�ciency of your air conditioning systems, as well as increasing its useful lifespan and lowering the risk of failure.

If you cannot remember when your last TM44 inspection took place, then now is the time to review your air conditioning estate, check paperwork and seek out an Accredited ACI Inspector.

TACKLING THE SKILLS SHORTAGE

TO ENSURE A BRIGHTER FUTURE Malcolm Anson, President of the Building Controls Industry Association (BCIA), explains why investment in training is essential if we are to drive the HVAC and building controls industry forward.

T

he ongoing skills shortage is a well-known topic of conversation in our sector, as well as nationwide. To address this issue, a robust plan of action is essential with training high on the agenda.

Research conducted by Engineering UK found an additional 1.8 million engineers and technically qualified people are needed by 2025. The study also discovered that people are put off by a career in the industry due to not understanding the various job roles or the importance of the sector.

There is an urgent need for perceptions to change, and to increase recognition of the work that we do. We should be reinforcing the message that our industry has a substantial influence in reducing the UK’s carbon footprint and creating sustainable environments, now and for the future.

The government has made a strong commitment to zero carbon buildings and the EU requires member states to achieve “nearly zero energy” buildings from 2019.

Government targets

Furthermore, legislation requires a reduction of 9% on carbon emissions on commercial buildings as a collective, with the aim of an 80% reduction by 2050. Building controls are integral in meeting the building performance challenge and meeting the stringent government standards.

What’s more, an ongoing industry wide commitment to invest in training is required. Our own engineers, clients and other engineering disciplines need to fully appreciate building controls.

The industry will benefit from skilled and knowledgeable professionals, who have the ability and confidence to install

effective controls and systems. This will ensure that buildings achieve maximum performance as well as the ultimate objective for the end user - a return on their investment.

One of the ways in which this is possible, is to keep abreast of the latest technologies. Technicians must be able to strongly communicate and be able to problem solve – this is key. We must strive to make sure technicians are suitably skilled to help understand their client’s needs and advise them appropriately. With an ever-changing need for high performing buildings, the industry needs to continue to evolve alongside technology.

This is where training is so crucial. For example, the BCIA have their own suite of specialist training courses which are aimed at all ages. These courses offer many benefits to those transferring into the HVAC industry and for those already employed in the sector, wishing to further enhance their knowledge.

Following the recent budget, Chancellor Philip Hammond has confirmed a major investment for 16-19-year-old students to undertake technical training. New technical qualifications called T-levels

SEPTEMBER 2017

Training_BCIA.indd 48

14/08/2017 17:35

T R A I N I N G

will be introduced between 2018 and 2022, with the aim to upskill young people, as well as to simplify the process of vocational training in England for construction and engineering.

These new qualifications will be a welcome boost in raising the profile of the industry and will go a long way in helping to shape the future of the HVAC and building controls sector.

By being proactive and engaging with the next generation of capable technicians and engineers, we can continue to move the industry forward in the right direction.

We need to be boosting our productivity by reaching out to the brightest and most promising talent in the sector and showing them that a longterm future in the industry is a rewarding and fulfilling one.

Fresh thinking

However, as well as enticing skilled young talent into our industry who will provide fresh thinking and innovative ideas and solutions, we also need to consider the needs of the industry today. What about the many skilled professionals who already exist – isn’t it time that we started to showcase their skills?

Whilst it is true that we need bright, new talent in the industry, we also need the industry stalwarts who can keep the industry running at peak capacity today.

Those individuals could have learned on the job or have come from a different profession. Perhaps they trained as an

49

electrician in the first instance and then like many others, have transferred smoothly into the building controls industry. It is people like this, who are just as important to our industry, if we are to plug the skills gap which seems to get ever wider.

Industry stalwarts

Gaining new skills is only one part of the story. Demonstrating proficiency is equally important, which is why the BCIA is proud to be working with organisations who can help members of our industry to prove their hard-earned credentials.

For example, the BCIA has worked alongside JIB to introduce a new Electrotechnical Certification Scheme (ECS) card for building controls professionals – something which is instantly recognisable and demonstrates the skills which have been achieved by members of our industry.

More importantly this allows members of our industry to wear their skills and training with pride – because whether we are young or old we should be proud of our achievements.

Bridging the skills gap will continue to be important. Continuous investment and commitment to training is the only way that we can ensure we increase our knowledge and expertise. By doing so, we can achieve more sustainable, energy efficient buildings which meet ambitious government targets in order to conquer the building performance challenge. www.bcia.co.uk

NIBE MOVING TO BRIDGE INDUSTRY TRAINING GAP NIBE Energy Systems believes it is providing a much-needed skills solution with the creation of a specialised course at one of its training and education centres.

N

IBE has launched its British Plumbing Employers Council (BPEC) heat pump course, an industry recognised qualification which is required for installers to become or retain MCS accreditation at its training facility in Chesterfield.

Robin Adderley, Sales and Marketing Director at NIBE, said: “It had become apparent that installers were finding it more and more difficult to source this essential training, either to become newly qualified or to update their existing qualifications.

“As this plays a vital part in our sector of the plumbing and heating industry we decided to offer the course via our existing, well respected training centre to ensure the future of renewable heat pump systems was reinforced from an installer angle with the required support across the UK.” The course, which allows installers to satisfy the growing demand for the installation of renewable energy heat pump systems in domestic and

commercial settings, will allow installers to consolidate their ability to not only install, but also maintain, a variety of heat pump systems including ground source and air source, both of which continue to grow in popularity.

Growing demand

Candidates should ideally have in excess of five years’ experience in an associated field (plumbing or heating engineering) and a qualification which equates to NVQ Level 3 in plumbing, heating or engineering. However, the course is also available to those that are currently working towards such qualifications to allow them to gain specialised training in the newest sector of the industry.

Robin added: “Renewable energy heat pump systems are becoming increasingly popular and it is important that the correct training is given to heating installers to enable them to competently and professionally install these niche systems.

“We take great pride in training and have NIBE VIP Installers that have undergone programmes on installing our own systems. To be able to support the industry by offering this additional course will place installers in a very strong position to be able to cope with the growing demand for heat pump systems competently, and with confidence.”

NIBE’s BPEC Heat Pump Course will last place over three days at NIBE Chesterfield. It is suitable for existing BPEC holders who need to re-new and also new installers seeking the qualification for the first time. The latter is subject to qualifying conditions. The course costs £360 per person including VAT. Course dates to date are 17-19 October and 14 -16 November. www.nibe.co.uk

LIFE’S A BEACH FOR KENSA AT PERRANPORTH How ground source pumps will provide 100% heating and hot water for homes on the Cornish coast.

The drilling team and Kensa Heat Pumps on site

A

luxury housing development amongst the dunes of Perranporth beach in Cornwall will use ground source technology from Kensa Heat Pumps to provide heating and hot water to the 40 apartments and homes.

Acorn Blue is building The Dunes on the site of a derelict hotel, with completion scheduled for June next year. The groundworks stage is now complete for Kensa’s Shoebox ground source heat pumps, which will be sited inside each of the homes to provide 100% of the heating and hot water for two apartment blocks, �ve coach houses and four beach houses.

Simon Lomax, Kensa Heat Pumps Managing Director, said: “Given its spectacular location alongside one of Cornwall’s premier beaches, we applaud Acorn Blue’s pioneering decision to specify ultra-low carbon heating systems for The Dunes. Investing in ground source heat pump systems will ensure the lucky purchasers bene�t not only from the lowest possible running costs but also a

technology which is remarkably reliable and durable. Best of all, this renewable installation is entirely unobtrusive so there is no visual intrusion on such a stunning setting.”

The ground source heat pump system features communal boreholes dug in the periphery of the site, six metres from the edge of the dunes, to depths up to 130m.

In total 3km of borehole pipework has been installed.

Natural candidate

The communal system, based on Kensa’s micro-ground source heat network design, sees five district arrays consisting of 19 boreholes in total. The network approach qualifies The Dunes for 20 years of income via the Government’s Non-Domestic Renewable Heat Incentive (RHI). It is expected that the RHI income will more than offset the cost of the system.

David Stein, Acorn Blue PreConstruction Director, said: “Aside from the inherent advantages associated with the adoption of renewable energy in respect of improved SAP rating, lower carbon footprint, RHI payback and generally ‘feeling good’, The Dunes was a natural candidate for ground source heat pumps. There is no natural gas in the area and the geology is known to be highly suited to GSHPs.” The individual Shoebox pump in each property overcomes traditional issues of plant room design and is exempt from the Heat Network (Metering and Billing) Regulations. Unlike traditional district heating schemes it provides complete heating and hot water control to the homeowners, offering individual bills and freedom to switch suppliers.

Kensa will work alongside Acorn Blue’s M&E contractor to install the pump units and ensure compliance with the Microgeneration Certification Standards (MCS).

Each home is to be fitted with Heatmiser thermostats, which will talk to smart phone controls. Individual heat and electric meters will email daily heat and electric consumption data to Acorn Blue, enabling performance monitoring and compliance with RHI requirements.

EVO ‘A NATURAL EVOLUTION’

T

he new Evo series of ground source heat pumps from Kensa has received full MCS accreditation, enabling its UK-wide distribution.

The ErP A++ rated Evo series is currently available in 7kW, 9kW and 13kW models, with a 15kW model anticipated for late 2017.

Designed for larger new builds and renovation projects, the Evo will supplement Kensa’s Shoebox 3kW and 6kW models, which are aimed at smaller new builds.

Simon Lomax, Managing Director of Kensa, said: “The Evo series is a natural evolution of our award-winning product range and delivers enhanced benefits to both installers and end users. Installers benefit from substantial discounts and unrivalled technical support and discover that Kensa has created a simple-toinstall product, which has been central to our offer since 1999. End users benefit from 15% efficiency enhancements over the Compact range, which results in higher Renewable Heat Incentive income and lower running costs, whilst the new models are not only ultra-quiet but also feature an aesthetically pleasing design.

“We have involved expert installers in the development phase and have experienced a massive surge in interest: this is a long-awaited product which should ensure Kensa remains at the pinnacle of the GSHP industry in the UK.” www.kensaheatpumps.com/evo

FREE YUTAKI TRAINING FROM HITACHI

H

itachi is offering free heat pump product training to installers at its aircademy training centre in Maidenhead.

Since the launch of its heat pump course in late 2015, Hitachi’s specialist heating team has enabled more than 700 installers to get ‘hands on’ with the

full range of Yutaki heat pump products and controllers.

Led by Andy Henson, Hitachi Heating’s technical engineer and training manager, the course was initially run over two consecutive days covering design, installation and electrical considerations as well as the monobloc and splits products. Following feedback from both distributors and installers, the content has now been packed into an intensive one-day course to make it easier for busy contractors to fit training into their work schedules.

Andy said: “Since the start of 2017 we have welcomed more than 250 heating engineers into our Yutaki product training.

“We’re also training a number of installers from Ireland and Scotland courtesy of our valued distributors in those areas. Getting heating engineers excited about the opportunities presented by air source heat pumps is great for both manufacturers and distributors, and will help get the message out to the domestic market about the many benefits of installing renewables.”

The new one-day course runs weekly in Maidenhead (and by request in Dublin) and is usually priced at £95 + VAT per delegate but, for a limited time only, Hitachi is providing its Yutaki heat pump training free of charge to suitably qualified installers. Refreshments, lunch and all course materials are provided and there is plenty of free onsite car parking available.

PANASONIC’S NEW GENERATION GAS-DRIVEN VRF

P

anasonic has unveiled the next generation of its gasdriven VRF heat pump, aimed at providing a heating, cooling and hot water solution for large-scale commercial projects.

The company says use of a gas-driven engine reduces the consumption of electricity to just 9% of an equivalentsized electricity-powered VRF solution, making it ideal for projects where there are restrictions to the power supply, enabling the building’s power supply to be used for other critical infrastructure such IT servers, commercial refrigeration and other building services.

The GHP runs on either natural gas or LPG and a single-phase power supply, which reduces the capital cost required to upgrade power substations to run heating and cooling systems.

The unit claims the ability to meet high demand for DHW by capturing waste heat from the engine generated during heating

and cooling. It is able to deliver hot water at 65°C without requiring additional electric heaters.

The GE3 range boasts 100% heating capacity and DHW at temperatures as low as -20°C without requiring a defrost process. Multiple units can be combined in configurations up to 60 HP. The seasonal energy efficiency rating (SEER) has increased to over 1.9 and the seasonal coefficient of performance (SCOP) has also increased to above 1.3. The GE3 series features a number of technical innovations, including a redesigned fan, a new type of heat exchanger and larger engine pulley, which deliver more powerful and efficient performance, reduce electricity consumption even further and better partial load control.

Since the first GHP unit was introduced in 1985, Panasonic has sold over 200,000 units. www.aircon.panasonic.eu

WOME N I N ACR

WOMEN in the

ACR industry

D I A N A

M A D R A

This month, the ACR Journal interviewed Diana Madra, Lead HVAC Design Engineer for Johnson Controls, Navy Systems.

What do you specialise in now?

I design the HVAC systems for Navy vessels.

What excites/interests you about the industry?

The constant challenges and the requirement for bespoke systems and solutions. Navy HVAC systems are unique and you face completely different problems to those in commercial HVAC systems.

Thanks to working on international projects you get to meet people from many different countries and get the opportunity to see and learn about different cultures. You also need to know different rules and regulations as different countries have different requirements.

HVAC itself is also developing and the requirements changing, which requires that you constantly need to develop your own skills and knowledge.

How do you see your career developing?

Where did you study?

I studied Environmental Technology at the University of Technology in Wroclaw, Poland (Politechnika Wroclawska ), specialising in Air Conditioning and Heating systems.

What was your first job?

My first real job after graduating was providing sales support at a refrigeration equipment distributor in Poland.

What attracted you to the industry?

I thought HVAC sounded interesting because of the wide variety of tasks and challenges. It is not just about designing ventilation ducts and selecting the cooling equipment, it also involves calculating the heat loads, analysing the noise and vibration, working with customers and suppliers, resolving integration challenges, and much, much, more.

you should try do this the best you can.

It means that you need to ask questions, seek information and grow your skills all the time.

What are the challenges of this industry?

For the part of the HVAC business I am involved with, each system is bespoke, different rules apply and there are different requirements and vessel designs. Also, the space constraints onboard Navy vessels makes it extremely challenging to fit all the necessary system components, equipment and ductwork.

What are the benefits of being in your role?

KOOLTECH CLAIMS TOP SPOT ON RODNEY ON HIS BIKE FOR HRS GOLF DAY TO REMEMBER EPIC CHARITY RIDE Building services engineer Rodney Clarke is to cycle 300 miles through South East Asia for charity.

The 18-hole Stableford winning team, Kooltech

The Hampshire Refrigeration Society celebrated its 30th annual golf tournament at the prestigious Old Thorns Manor Hotel, Golf & Country Estate.

During the day 120 players took part in the activities which began with a 9-hole Texas Scramble to loosen everyone up and get to know their playing partners. After a hearty breakfast brunch the teams then competed in an 18-hole Stableford competition where the 30 four-ball teams battled for the winners’ Claret Jug and other fantastic prizes. The winning team was Kooltech, captained by Ian Waterfall, who returned to the clubhouse with 89 points. Second were Bob Scottow’s Seagulls with 87 and third John Hobley’s FSW team with 85.

The competition was very closely fought and the �rst six teams all had totals in the 80s.

Another 18 prizes were awarded, including Nearest the Pins, Longest Drive, Best Handicap winners and runners up, Best Gross and Nett Scores and the “I need to play more golf” prize. This was presented to Damian Wiszniewski of HRP, who was delighted to take the award in his �rst competitive tournament.

HRS chairman John Emm said that the day was a huge success and paid tribute to the Old Thorns sta�, the HRS organising committee and the 23 RAC companies who provided support and sponsorship.

The HRS is already organising its Xmas Fun Day Golf event for December and started planning for next year’s tournament.

Rodney, 52, who works for Dodd Group, will be joining an 18-strong team from across the UK in cycling from Saigon Neil Gibbard of Coolair, left, with Rodney Clarke in Vietnam to Angkor Wat in Cambodia over six days starting on 28 October to raise money for Challenge Cancer UK. Having smashed his individual target of £3,000 in only three months, he is now aiming to raise £5,000.

The ride has been organised by the Cannock o�ce of one of his employer’s suppliers, air conditioning installation specialist Coolair Equipment. Coolair, which has its headquarters in Manchester and another o�ce in Maidstone, led a similar expedition in 2015 that raised £90,000 for Challenge Cancer UK, which splits the donations it receives between ten national cancer charities.

Neil Gibbard, Coolair Regional Director and the event organiser, said: “Rodney has been leading the way in raising sponsorship money for our bike ride as we aim to raise a record-breaking six-�gure sum this year for such a great cause.” www.justgiving.com/Rodney-Clarke
