A few days spent in Kigali, Rwanda by government officials from around the world in October made it to the front page of media outlets. And, why?

They agreed to phase-down HFCs (Hydrofluorocarbons) in their countries at various stages to get rid of these greenhouse gases.

It was not a perfect agreement, in that some commentators wanted more phase-down faster. Developing countries said they needed more time to wean themselves of HFCs. But, the fact is that it was an important moment for the planet and humans.

The Kigali agreement means businesses and organisations will have to adopt new refrigerants with low global warming potentials (GWP). And, they will probably have to invest in new systems when their old units break down. That is good for our industry.

Big questions about refrigerants is which low GWP refrigerant to use and how long will they be viable to use? Some refrigerants have ultra-low GWPs, which suggests they might be around for longer.

Which suggests that professionals in our industry need to help their customers focus not just on the capital expense of new systems, but the total cost of ownership of a new cooling system which uses a low GWP refrigerant.

NOVEMBER 2016 Starbucks, Emsworth interior

STARBUCKS GETS FIRST SAMSUNG 360 DEGREE CASSETTES

Starbucks customers are enjoying the bene�ts of Samsung's new 360° air conditioning system, thanks to the UK's �rst installation by DCI Refrigeration & Electrical.

The American co�ee shop chain now has the 360° air conditioning cassette installed in its branches in Emsworth, Hampshire, and St. Leonards, Dorset. The installation works with ventilation system desgined by DCI, and were speci�ed because of the mix of style, modern looks and fast, all-round �ow. The circular cassettes are bladeless too.

Samsung's designers were inspired to make the 360° air conditioning cassette by wind turbines, which make air�ow more e�cient by introducing a sub-air�ow through their blades into the main air�ow. The Korean company wanted the new cassette air�ow to be similar to a natural breeze, counter to traditional cassettes which can sometimes feel as though they create cold drafts.

DCI installed four 360° cassettes in the newly-built Starbucks sites, the franchises of which are UK franchisee 23.5 degrees Limited.

B&Q CHOOSES LG FOR R22 AIR CONDITIONING REPLACEMENT IN 250 UK STORES Korean air conditioning giant, LG Electronics, is the manufacturer of choice in over 250 B&Q stores across the UK, thanks to a contract won by Sugoi Solutions.

The Bristol-based contractor worked with LG to replace the home improvement chain's existing air conditioning systems which used R22 refrigerant, now banned under F-Gas legislation.

The contract, which is worth around £1.4 million, was a logistical challenge to replace the previous units with over 1,000 LG air conditioning units. B&Q has new LG split and multi split cooling in the administration and sta� areas in its stores, which stretch from Scotland to the Channel Islands.

Sugoi created a detailed photographic inventory of all the installed units, and carried out extensive surveys, testing and assessments to ensure the success of the project.

Sugoi director Ben May, said: “We’ve attended all the sites and organised access to the air conditioning systems, organised for the safe disposal of the R22 refrigerant in each case, sorted the removal and disposal of the existing kit and reinstalled like for like equipment. We’ve audited the work throughout the process and achieved 96% scores on the on-site audits of our work and as a result of the work we’ve done we’ve secured the maintenance contracts on all the equipment we’ve installed. We’ve provided comprehensive documentation for every store and for every piece of equipment we’ve installed.

“This is the biggest single contract we’ve ever undertaken and we’re very proud of the outcome. LG equipment is excellent to work with and the support we’ve had from LG has been �rst class.”

SWEGON BUYS RUSKIN AIR MANAGEMENT

NEW REFRIGERATION RESOLUTION ANNOUNCED BY CONSUMER GOODS FORUM The organisation representing food retailers and manufacturers, the Consumer Goods Forum (CGF), announced renewed commitment among its members to phase out HFC refrigerants.

The CGF agreed a new resolution which calls on companies to rid their business of hydro�uorocarbons (HFCs) used in refrigeration and air conditioning systems. The organisation is striving to meet its goal of helping to reduce global warming. HFCs, the CGF states, make up 1.5% of all warming potential today. Experts believe that HFCs could be between 6% and 9% of all greenhouse gases by 2050 unless urgent steps are taken to eliminate them.

The Forum's resolution has four focuses, namely installing new refrigeration systems in viable markets, overcoming barriers in markets where installing refrigeration equipment is not viable now, reducing the environmental harm caused by existing refrigeration systems, and developing individual targets and plans to address the �rst three points.

Legislation is very in�uential in bringing about change and the CGF wants HFCs to be included in the Montreal Protocol.

CEO of Sainsbury's, Mike Coupe, said: "Once again CGF members are showing global and environmental leadership, and this latest move will play important role in achieving wider sustainability standards in the industry. As we move away from HFC gases and towards cleaner business practices, it's crucial that the consumer goods industry continues to lead the way and stay ahead of the curve."

Members of CGF have spent the last six years testing new, low carbon refrigeration systems in over 4,000 supermarkets, as well as using natural refrigerants in four million chiller units and industrial refrigeration systems worldwide. The results are published in their 'Refrigeration Booklet'. Their results appear positive overall with the natural refrigerants. However, the CGF announcement shows that there is still much work to do eliminate HFCs from refrigeration systems globally.

Swegon has bought Ruskin Air Management Ltd, the company known for its ventilation, �re and smoke control products.

Ruskin Air Management has 220 employees across its two UK sites in Whitstable, Kent and Bridgnorth, Shropshire. The business has been making its air management products for over 50 years.

Swegon's CEO, Hannu Saastamoinen, said: “This acquisition gives us a very strong local presence and identity in UK through the well-known RAML brands. In addition, with RAML, we add a new competence area in Swegon in form of their extensive �re & smoke product knowledge. RAML products are complementary for us and we see good potential for cross sales in the future. As a long-term industrial investor, our aim is to reinforce and further develop the local manufacturing base in both Whitstable and Bridgnorth, which are excellent in producing customized products for the local market with short delivery times."

Ruskin Air Management's managing director, Kevin Munson, said: “This is a perfect match for Ruskin Air Management Ltd. and we look forward to continue our growth momentum as part of the Swegon Group.”

Swegon bought Ruskin from Johnson Controls for an undisclosed sum.

A GAS TO INVEST £1 MILLION INTO NEW REFRIGERANT RECLAMATION SYSTEM Bristol-based refrigerant experts A Gas have announced a £1 million investment into a new refrigerant separator their operation just outside the city in Portbury.

The company is predicting that the refrigerant reclamation market will expand because of the F Gas regulations which restrict the availability of high global warming potential (GWP) refrigerants in the market.

The company predicts that the new separator will be operational by the second half of 2017. The new plant will more than double its current capacity to reclaim refrigerants.

A Gas managing director, John Ormerod stated: “The investment is in response to the F-Gas Regulations.

Supplies of reclaimed refrigerant are crucial to ensure that there is enough gas on the market to meet demand. We are already seeing changes in market patterns and as a major supplier of refrigerants we have to respond to this.

“The new separator is a key investment by A-Gas, will operate in tandem with the existing separator on our Portbury site and will more than double our reclamation capacity here.

This investment also highlights our commitment to providing the industry with the necessary capacity and infrastructure to support the F-Gas phasedown.”

A Gas will be able to reclaim mixed refrigerants which it receives from customers across Europe.

GLOBAL DEAL COULD AVOID 70 BILLION TONS OF CO2-EQUIVALENT HFC EMISSIONS

An historic, global deal was signed last week in Kigali, Rwanda which aims to control the production and consumption of hydro�uorocarbons ( HFCs) which are believed to big contributors to rising temperatures around the world.

The so-called Montreal Protocol now has an amendment cap HFC use and phases its use down from 2019 among developed and developing countries at di�erent stages.

Governments hope that the agreement, which took eight years to negotiate, will avoid 70 billion tons of CO2equivalent HFC emissions.

Developing countries, including China, will freeze their HFC consumption from 2024. However, countries including India, Kuwait, Pakistan and Saudi Arabia have agreed to freeze their HFC consumption at a later date.

EIA UK’s Climate Campaign Leader, Claire Perry, said: “Compromises had to be made but 85 per cent of developing countries have committed to the early schedule starting 2024, which is a very signi�cant achievement.

“According to our initial calculations this deal will avoid more than 70 billion tonnes of CO2e emissions by 2050 – which will be close to avoiding a half a degree of warming.”

John added: “This type of waste has changed over the years as refrigerant mixtures get more complicated and we start to see much higher quantities of mixed gases. Several di�erent refrigerants combined together in one mix sets us new challenges and without separation technology it is almost impossible to return the gas to the same kind of quality as virgin material.”

A Gas is rapidly becoming a big player in the refrigerant reclamation market. The company recently bought the US Company Rapid Recovery, and they now reclaim thousands of tonnes of refrigerant around the world each year.

n addition to extensive equipment training, we have a technical helpdesk available to advise engineers when they are on site.

One of the things I’ve noticed when speaking to our technical team though is the number of calls they get from engineers who could have found the information quicker than the time it takes to make a phonecall.

We have a number of Apps and Tools designed to provide answers to the more straightforward questions that you will face on site.

Our ME Engineer App has been designed by engineers for engineers, specifically to resolve straightforward questions and because you carry it round with you on your smartphone, it can get you the answer you need far quicker than needing to call the helpdesk.

It includes a refrigerant calculation tool as well as a spare parts look up facility and a fault code finder.

We love calls to our helpdesk and when you are out on a job and have a deeply technical issue you need to resolve, then you need to speak to an expert – and you want to be able to get through on the phone as quickly as possible.

My point though is that if you use the Apps we have developed, you will 1) solve your issue quicker and 2) leave the helpdesk free

for someone with a more complex issues.

We can also update the App content within minutes so you will always have the latest technical support, right in your hand – and the ‘favourites’ options, means you can set the App to instantly show the most used functions directly on start up.

As a responsible manufacturer, we are always looking for ways to make your job easier out on site and over the next few months I want to use this column to focus on some of the other reoccurring issues that our helpdesk have noticed to see how we can help you more.

Ben Bartle-Ross is a trainer at Mitsubishi Electric. If you have any comments on this column of any other training issue contact him by email: Ben.Bartle-Ross@meuk.mee.com ME Engineer is available from most App stores and if you do need to call the technical helpdesk, including out of hours emergency support service phone 0161 866 6069.

CHILLER CABINET SLIME: WHY CLEANING IS NOT ENOUGH Bacterial slime in the condensate tray is a leading cause of blown fan motors and refrigerator leaks.

Advanced Engineering technical director Colin Pratt explains why it keeps coming back.

E

very refrigeration engineer seems to have their own way of removing the thick slime that tends to build up in a retail chiller cabinet’s condensate tray. Pressure washing, steam cleaning, wet & dry vacuums – we’ve even seen footage of contractors competing to suck up the biggest “jelly snake”.

Chiller cabinet slime

But all these methods have something in common: more often than not, when you make your next scheduled service visit, the slime will be back.

And that’s more than just a messy nuisance. When the build-up inevitably blocks the condensate drain line, the water level will start to rise.

“

MORE OFTEN THAN NOT, WHEN YOU MAKE YOUR NEXT SCHEDULED SERVICE VISIT, THE SLIME WILL BE BACK.”

is, where it comes from, and what it does.

The microbes themselves multiply quickly, because a chiller condensate tray is a perfect environment: moist, and with a constant supply of food particles. As they grow, they excrete an exopolysaccharide layer – the slime we all know.

The exopolysaccharide forms a protective biofilm: a miniature ecosystem where various kinds of microscopic organism can flourish, shielded from biocides and most cleaning agents.

Inside the biofilm, germs are 500% more resistant to antibacterial treatments.

Importantly, the polysaccharide is not soluble in water. So even when a cabinet is cleaned thoroughly, small traces remain and begin to grow back immediately.

Microbe numbers increase exponentially, so bacterial slime can re-block the condensate tray just weeks after a visit.

The least you can expect is a leak, spilling out onto the shop floor as the tray starts to overflow – and if the water reaches the fans? There’s a reason UK retailers buy literally hundreds of thousands of replacement refrigerator fan motors every year. If the fan fails, the coil itself can become encased in a block of ice: hardly ideal for heat exchange.

Food safety risks

The chiller might limp on for weeks – leaking, and trying to maintain the set temperature with blown fans and an impaired coil – before the added duty load causes another component to give out.

It’s not ideal for food safety – and that’s before considering the microbes in the condensate tray. We sent samples from a typical UK supermarket for independent laboratory analysis, and they found up to 11 million bacteria living in a single millilitre of condensate slime.

Worryingly, these included biocideresistant bugs like Staphylococcus, as well as organisms that can cause pneumonia, fever and bloody diarrhoea. All just centimetres away from the food, in a direct flow of air into the cabinet and out into the store.

Cleaning essential, but insufficient In order to remove the bacteria fully, it’s important to understand what the slime

Advanced Engineering.indd 16

Step by step

To stop the slime returning so quickly, there are three steps which must always be followed. Before the bacteria can be treated, we need to break down the exopolysaccharide slime into smaller, more soluble molecules. This, in turn, will expose the germs to treatment. Finally, a lasting dose of biocides and surfactants will stop new slime forming.

Crucially, if you’re cleaning a refrigerator for food, all the products you use to complete the process should be NSFapproved for use in food handling areas.

AT ADVANCED, HERE’S WHAT WE RECOMMEND. 1. Clean away the exopolysaccharide Chemical hydrolysis will break the long chains of polysaccharide. DrainSafe is especially formulated for the job, and will dissolve biofilms –in the drain – in a matter of minutes. It’s also safe to use with condensate pumps.

2. Kill all the microbes Because some of the bacteria found in chiller cabinets are naturally resistant, it’s important to use a cleaner with a cocktail of biocides and surfactants – effective on bacteria, algae and mould.

Our CoolSafe cleaner fits the bill – and comes in concentrate or a ready-touse sprayer.

3. Protect the tray from re-growth Treating the condensate as it flows through the tray and into the drain, using a slow-release agent to stop microbes growing back. Our new, pink Jally Strips include the blend of surfactants and biocides needed to kill all the relevant organisms.

Amplify the effects of cleaning Jally Strips are not an alternative to a rigorous cleaning and maintenance regime, but they can make its effects last longer – up to a year in most cases – and prevent problems before the next scheduled maintenance visit.

One supermarket told us that adding this essential, final stage has directly contributed to a 3,500 year-on-year reduction in refrigerator condensate leaks.

That’s almost ten leaks fewer, every day. It means fewer callouts and a better in-store environment, as well as knock-on savings like a 25% reduction in their expenditure on absorbent floor socks. Happier customers, lower maintenance costs.

Until now, many engineers had considered it inevitable that they’d find slime under a chiller cabinet’s base plate. But with the right process, it can now be as clean as you left it a year ago.

AIR CONDITIONING:

MORE IMPORTANT FOR HOTEL REPUTATIONS THAN YOU THINK

Hotels that fail to provide good air conditioning for their guests can have a poor impact on their online reputation, a survey by Synecore recently found.

P

oor air conditioning might also show that hotels are not implementing their legal obligations to maintain their systems, according the Kent-based air conditioning business.

Air conditioning is standard in many hotels rooms around the world today. It is not only hotels in hot countries that have air conditioning fitted in guest rooms.

Hotel rooms in cooler countries like Britain also use cooling systems.

Synecore’s survey found that, in London, guests often complain about the lack of, or badly maintained, air conditioning in the city’s hotels. Unhappy guests post their feelings about the poor AC in online travel sites which can badly damage hotel’s reputation.

In fact, the well known travel review site, Trip Advisor’s ‘Trip Barometer’ study shows travel trends in 2016. The study found that 63% of travellers around the world said that air conditioning was a requirement when they looked for places to stay. Air conditioning was more

20-21 Synecore.indd 20

important to them than breakfast (40%), or a swimming pool (26%).

Synecore is a professional Mechanical and Engineering contractor that works with hotels throughout the UK helping them with their air conditioning design, installation and maintenance.

The company has set itself the task of educating hotel customers on the importance of a good air conditioning systems in their guest rooms for their online reputations. It is difficult for hotels to rebuild their reputations once guests complain online on sites like Trip Advisor.

Synecore’s HVAC manager, Gary Piper, says: “It is surprising that so many hotels do not provide good air conditioning as a basic service to their guests.

Our research has discovered that the main complaints relating to poor air conditioning in hotels are largely due to under maintained systems that don’t perform efficiently. Shockingly, complaints are often ignored, or a fan

is provided as an alternative. In these instances, we firmly believe the negative comments are well deserved.

“Keeping your air conditioning system well maintained is not difficult, especially with Planned Preventative Maintenance Schemes, such as ours, where the air conditioning system is regularly serviced, cleaned, checked for leaks and tested. Most importantly these undermaintained systems could be a sign the hotel is not fulfilling its legal obligations of remaining FGas compliant and they possibly do not hold an up-to-date TM44 assessment.

“Large air conditioning systems, often found in hotels, must be regularly leak tested to prevent the release of harmful ozone depleting gases being released into the atmosphere. A poor performing system could be a sign of a leak and it must be rectified immediately, or the hotel could receive significant penalty fines if not addressed.”

The biggest complaints about air conditioning in London hotels include: Having to open windows to get some fresh air into the room in a city when the high noise level of traffic in the streets by day and night make getting some rest difficult. Often, hotels restrict how far guests can open windows for safety reasons, which restricts the air flow in and out of the room.

Smelly and noisy air conditioning as a result of poor maintenance leaves a poor impression of the hotel for guests. And, when guests’ concerns are not dealt with quickly, the hotel is very likely to get a negative review.

Ineffective air conditioning, or systems with complicated controls frustrates guests. It also might mean that an AC unit is leaking, which is illegal. Any units like this must be serviced immediately unless the hotel wants to face heavy fines.

Air conditioning in the public spaces in a hotel, but not in the guest rooms gives the impression that paying guests are less important than the staff.

20-21 Synecore.indd 21

“KEEPING YOUR AIR CONDITIONING SYSTEM WELL MAINTAINED IS NOT DIFFICULT, ESPECIALLY WITH PLANNED PREVENTATIVE MAINTENANCE SCHEMES”

Hotels that have had negative reviews have,however, responded by updating the air conditioning in their rooms, according to Synecore. Some hotels with good air conditioning get high praise from guests which shows how important it is for them.

Hotels that ignore bad feedback about their air conditioning often do so, according to Synecore’ survey, do so because their don’t realise it is possible to install it in their buildings.

Or, they often do not have a repair contract in place.

Gary Piper responded by saying: “We design and install bespoke air conditioning systems for all types of commercial properties, there are no limits. We only use products from leading manufacturers to ensure the systems we install last. They also come with payment plans and competitive warranty periods, when combined with our Planned Preventative Maintenance (PPM) scheme, which offers a 24/7 call out service. So, there really are no excuses for hotels not giving guests the basic service of good air conditioning.”

Synecore’s tailor PPM plans to meet the needs of the individual hotel. The PPM service also ensures an air conditioning system remains F Gas compliant and has an up-to-date TM44 assessment. All businesses with air conditioning installed have legal obligations to fulfil.

Hotels that need advice on installing or maintaining an air conditioning system, or that worry that they might have an air conditioning leak should contact Synecore on 0845 241 4953 or visit www.synecore.co.uk

HEAT RECOVERY: HOW ONE POULTRY COMPANY REDUCED ITS ENERGY BILL Soanes Poultry has reared poultry in Yorkshire for over 65 years. But, the ageing air cooled condensers in its refrigeration plant were struggling to keep up with demand from their production line.

Graham Stuart, Ken Riley and Nigel Upson in front of the DK Heat Recovery water tank installed at Soanes Poultry

T

he current air cooled condensers use cold bore water spray jets in the warm summer months to help them cope with cooling needs. However, the system was barely able to keep up with the cooling demands required

by Soanes to get enough poultry products through the line.

The company needed a solution to help deliver enough cooling capacity which would pay for itself quickly. Also, Nigel Upson, general manager at the poultry firm, needed a solution which would enhance their production output and save them energy.

Suggested and Actual Solutions

The first suggestion was to install additional systems and to replace the

DK HEAT RECOVERY SOANES POULT.indd 22

existing air cooled condensers with new units. That was going to costs Soanes around £40,000.

DK Heat Recovery had another suggestion to solve the problem. Their solution would not only solve the

Kit List 1 x DK fully insulated food grade standard 2,000-litre hot water tank complete with 144kW of twinwalled food grade standard EN1717 heat exchangers.

4 x DK suction gas heat exchangers delivering improved cooling efficiency of 8%

problem; it would reduce their energy consumption and cost less than the first suggestion. DK's engineers proposed a suction gas heat exchanger solution. It would improve the refrigeration efficiency by 8%. The solution would also provide the company with 2,880 litres of hot water an hour, which Soanes could use during its production process. Soanes uses 45,000 litres of water a day in production.

Impressive Results

Using the heat recovery solution, DK helped Soanes get the room temperature they needed on time.

And, it reduced the compressor runtime, which cut out more energy costs. Half of the condenser fans worked in 'idle mode' through the hot 2016 summer thereby using less energy too. The heat recovery system diverts

“WITH LESS ENERGY USE, SOANES MANAGED TO REDUCE ITS 144kW per hour from the air cooled condensers.

With less energy use, Soanes managed to reduce its hot water boiler costs by 90% too. The business relies on LPG because of its rural location it is off the mains grid.

And, the firm did not need to use any of its precious bore-hole water through the summer to spray onto the condensers.

Soanes is set to save enough money on the heat recovery solution to make it pay for itself within two years on the hot water savings alone.

HOT WATER BOILER COSTS BY 90%...THE HEAT RECOVERY SYSTEM HAS

MANAGED TO BOOST PRODUCTION CAPACITY TOO. IN FACT, SOANES HAS INCREASED ITS PRODUCTION BY 12% BECAUSE OF THE DK HEAT RECOVERY

SOLUTION.”

In this case, there was no further disruption because of the installation. DK did the work at the same time as the work to change over the refrigerant done over four Fridays when the company stops production.

What's the future for heat recovery in the UK?

The heat recovery industry has progressed recently in the UK, and it has a prominent place in a world which demands more from less from all aspects of business. But, there are no

L T R: Nigel Upson (Soanes), Ken Riley (DK Heat Recovery), Graham Stuart MP

government incentives for heat recovery. There is no energy input. Government support overlooks this important industry. It focuses on renewable energy in the main and not on recycling energy.

During the visit to the Soanes Poultry site, local MP Graham Stuart arrived to look at what the Yorkshire firm is doing with the heat recovery solution.

He is interested in raising the profile of heat recovery or heat recycling at Westminster to incorporate it as policy in the long term.

However, to achieve that the heat recovery industry needs to organise itself with a trade body. That will make it easier for Government to liaise with a neutral body rather than single companies with vested interests.

Given the results that DK Heat Recovery is getting at the Soanes Poultry site, and the straightforwardness of the installation, it's hard to see why systems which recycle heat are not more popular in the industry, where applicable.

It's common sense.

UK AND EUROPE TAKE CENTRE STAGE IN THE GLOBAL REFRIGERANT PHASE DOWN A-Gas Managing Director John Ormerod on how the phase down of HFCs in the UK Australian Low GWP Refrigerant Switch and Europe compares to refrigerant use in other parts of the world From January 2018 end-users in Australia

R

efrigerant quota reductions are approaching rapidly in the UK and Europe. This is already putting a considerable pressure on the supply chain and the refrigeration industry is beginning to face up to the prospect of shortages of high GWP HFCs. There are a number of alternatives available, ranging from low GWP HFCs and HFOs to natural refrigerants, which are opening a new window for end users and equipment suppliers.

John Ormerod

Worldwide Effect

But, the e�ects of the HFC phase down are being felt around the world too, as countries, including the US and Australia, react to the demands of the Montreal Protocol. In terms of getting rid of high GWP HFCs, Australia is currently behind the UK and Europe but well ahead of the US. Recently, the Australian Government announced that it is committed to reducing greenhouse gas emissions by 26 to 28 per cent below 2005 levels by 2030 and reducing the use of HFCs is a key part of this.

Australia is planning a statutory phase down of HFC imports beginning in January 2018 and it is hoped that this will reduce HFC emissions by 85 per cent by 2036. The

AGAS.indd 26

phase down is viewed as more ambitious than the proposals for global reductions being negotiated under the Montreal Protocol. It has a lower baseline – re�ecting Australia’s current demand – and more frequent reduction steps.

As part of this the Australian Government is promising to reduce the regulatory burden by changing the licensing arrangements for HFCs, encourage businesses to reduce refrigerant leakage and look at ways of extending the life of equipment. The Australian market will be moving into quotas in the near future which will put it ahead of the timetable laid down by the Montreal Protocol.

will have to begin the switch to low GWP refrigerants. This includes changing to new equipment or retro�tting, something supermarkets in Europe are already doing as they move away from what was once the go-to refrigerant R404A. It is in Australia’s favour that in this market there are already a sizeable number of CO2 installations in place.

This trend followed the introduction of a carbon tax on HFCs in Australia – which drove up the price of refrigerants – and persuaded supermarkets that CO2 made a good alternative.

In the UK, supermarkets have opted for an alternative strategy. They are already trialling non-�ammable HFO blends, R448A and R449A, in low and medium temperature applications. These next generation refrigerants combine optimum cooling with improved energy e�ciency and lower GWP. Small quantities of R22 are still used in Australia – although it is heavily regulated – with reclaimed gas �lling the pipeline.

Reductions in its use are planned year on year. In Europe and the UK Reclaimed R22 has been banned since January 2015. There is a raft of alternatives to R22 available in the UK, each designed to do a di�erent job, but there are no doubt systems in the UK still running on R22 illegally.

Refrigerant Reclamation

America Needs to Catch Up

It is fair to say that the recovery and the reclamation of refrigerants will have a key part to play in the HFC phasedown throughout the world as the economic and the environmental bene�ts begin to become more attractive to end-users.

This more holistic approach to refrigerant management will feature highly in the minds of end-users.

The UK leads the way with a range of complimentary services available to end users such as easy recovery, environmentally-friendly disposal of waste and laboratory-led analysis to reclaim gases and return them to a high standard for re-use.

Leak Detection and Prevention

Supermarkets in the UK and Europe have also recognised that �xing leaks is probably the �rst step along the road to a reduction in the use of HFCs. Nobody should be in any doubt that an e�cient leak reduction programme makes a considerable di�erence to refrigerant use and saves money long term. In Europe F-Gas has made a di�erence by accelerating the demand for better leak reduction regimes and the same can happen in Australia.

Spraying soapy water can no longer be viewed as a reliable way of detecting leaks. By using the latest leak detection products like Trace-A-Gas®, a �ve per cent hydrogen and 95 per cent nitrogen mixture from A-Gas, engineers are able to locate leaks and �nd evidence of former leaks quickly and e�ciently.

AGAS.indd 27

www.agas.com

In the US the refrigeration and HVAC industry is aiming to have HFCs phased down as part of the Montreal Protocol but they are well o� the pace compared to UK, Europe and Australia. The Americans are trying to catch up but it is fair to say that they are �ve to ten years behind the UK and Europe in terms of where they are.

In Australia the phase down of HFCs is only just beginning, the mechanics are in place but in this part of the southern hemisphere the industry is still looking for more information on how it will all unfold.

Perhaps it can learn from the experiences of others.

In the UK and Europe the introduction of low GWP refrigerants and blends, including HFOs some of which are mildly �ammable, will make a key contribution to phasing out high GWP refrigerants. They have a short atmospheric life and contribute far less to global warming than more commonly used HFC blends.

Together with better equipment design, higher safety standards and improved training, these factors will keep UK and Europe ahead of the game in meeting the demands of the Montreal Protocol.

BUILDING EQUIPMENT SERVICES -

SUPPORT AND MOUNTING OPTIONS Tom Fitzsimons, Area sales manager for Flexi Support Systems at Pump House Pumps explores solutions for supporting heating and cooling systems on buildings.

W

ith the increasing focus on environmental friendliness and low carbon emissions, modern buildings are invariably designed much “tighter” than they used to be and have a high priority on keeping cold out and heat in (and vice versa in the summer).

Also, when it comes to refurbishing older buildings, much consideration is given to the above and this this means that there has been a big increase in the use of environmental building control systems. These would incorporate heating, cooling, humidity, air filtration and purification equipment in both new build and refurbishment.

Therefore, there are a multitude of mechanical, gas and electrical services needed in buildings, such as air conditioning and air handling units of various sizes, chillers, condensers and fan sets, ventilation duct works, stand by generators, chillers and even complete plant rooms.

If possible, all this kind of equipment should be placed at ground level and in a safe area where working at height is not necessary and access for maintenance is easy. However, this often is not possible, particularly in areas with high building density, where placing equipment on the roof is the only practical option.

Of course, once on the roof, all these different types of equipment need supplying with services, meaning lots of cables, pipes, drainage channels, vent hoods or ductwork, running back and forth across the roof.

All flat roofs have some sort of waterproofing system in place and therefore it is essential to ensure that

28-29 Pump House.indd 28

anything placed on the roof will not damage that waterproofing and also manage the loading of heavy equipment such as condensers, VRF units, and Air Handling Units.

The Solutions

Small Equipment Mounting For lighter items, such as cable trays, pipe runs, small condensers and fan sets, simple options such as Flexi-Feet can be used. These are one-piece moulded rubber blocks in various sizes from 250mm to 1000m long that incorporate standard galvanised 41mm x 21nn strut to allow fixing down of the of units.

Another option for supporting this kind of equipment, as well as various sized ductwork, is to use H Frame kits.

The H frame kits are supplied with 2 feet (either 320mm square or, for heavy duty applications, 2 x 500mm square feet), angle brackets and fixings and the installer supplies their own strut. This allows the installers to “custom” build H frame supports to whatever size is needed to suit the job at hand.

Mid-Range Equipment Mounting For larger pieces of equipment such as condensers, VRF/VRV units or air handling units, along with associated items like ductwork, supporting pipe work and cable trays then a Flexi Modular Support Frame is ideal.

The Flexi Frame is a simple system which allows contractors to “design” their own systems. The Flexi Frame system comes in two options – either 1200mm x 1200mm or 1500mm x 1500mm but either size option has only two part numbers.

You start with either a 1200mm base frame pack or a 1500mm base frame pack and add as many 1200mm or 1500mm extender frames packs and needed to accommodate the length of the equipment or items of equipment being mounted.

The base and extender packs are supplied flat packed, so ordering and selfdesigning a system could not be simple.

Each base and extender frame has a safe working load of 500 kilos and has been load tested up to 5 tonnes.

A Flexi Frame Base Pack comes complete with 4 x 320mm square plastic feet with integrated rubber pads, 4 x adjustable leg inserts, 2 x 40mm x 40mm box section bars and 2 x 41mm x 41mm strut bars and all associated spring nuts, fixing bolts and washers. The rubber pad is adhered to the plastic foot and incorporates drain slots moulded to the underside to allow standing water to flow under the foot.

The Flexi Frame Extender Pack comes complete with 2 x 320mm square plastic feet with integrated rubber pads, 2 x leg inserts, 2 x 40mm x 40mm box section bars, 2 x 41mm x 41mm strut bars and all the associated spring nuts, fixing bolts and washers.

Heavy Equipment Mounting For very heavy pieces of equipment such as large air handling units, chillers, stand-by generators, and even complete plant rooms, then a Flexi Heavy Frame system is available.

Using large box section steelwork and larger 500mm square feet it is ideal for managing big loads.

Safe Access Solutions Another range of important accessories often needed on roof tops with equipment on is step-overs and hop-overs to go over pipework and drainage channels, as these provide safe access for engineers to get to the equipment for service and maintenance.

Standard access solutions are available from stock and bespoke solutions can be manufactured in about 15 days.

A complete design service, along with site surveys, load calculations and full AutoCad drawing services are available.

Summary

For any Building Equipment Services Equipment that need mounting or safe access to for maintenance there is a solution available that is both practical and affordable.

UNIVERSITY LOOKS TO BIG FOOT SYSTEMS FOR THE RIGHT SUPPORT Big Foot Systems has supplied support solutions, including bespoke air handling unit supports, for rooftop plant at a new Health and Biosciences building on a University campus. The new 11.5 million three-storey facility provides 5,000m2 of teaching and research space.

F

eaturing state-of-theart clinical and diagnostic equipment for health professionals and patients, the project required both air handling units and external condensers for cooling. The challenge for contractor was installing the large air handling units (AHUs), duct and external condensers in a confined area and without penetrating the roof. Big Foot Systems therefore provided the ideal solution with its range of non-penetrative building services rooftop support.

A standard support frame was not feasible for the AHUs as a specific finished height was required by the planning authority whilst still allowing for serviceable access underneath.

Instead, Big Foot Systems supplied individual 600mm feet with a fabricated top bracket to receive AHUs continuous skid, made feasible with the roof’s integrated wind protection. In addition, associated duct and pipe work were supported by large quantities of Big Foot Systems’ 305mm H Frames.

Later on in the project, Balfour Beatty also required a further support solution and so decided to request HD Frames, also from Big Foot Systems, for this part of the project.

“Sometimes traditional supports may not be suitable in meeting the unique requirements of a project. With the aid of our technical surveyors, highly skilled engineering team and use of engineering tools such as ANSYS (FEA/CFD) Big Foot Systems can design

BIG FOOT.indd 2

innovative design, the H Frame Set 305mm is interchangeable with three strut sizes with one foot fitting all.

The support is also compatible with industry standard componentry also adding to application flexibility.

Big Foot Solution’s HD frames are designed for each project with a frame similar in design and configuration to that of a standard light duty frame product but utilising larger and longer sectional bars, typically 50mm x 50mm or 100mm x 50mm, enabling the support of a large arrays of VRF/ VRV or a large heavy unit such as an AHU.

Simplifying installation

and manufacture complete one-off solutions,” explains Sam Birch, Product Manager at Big Foot Systems.

Versatility

Quick, versatile and economical, the H Frame Set is designed to support pipework, duct, cable ladders/trays or any combination of these, helping to ensure a safe and secure flat roof.

Offering a versatile application, installers provide their own strut keeping the duct and pipe installations low-cost by fabricating the strut frameworks on site. Featuring an

Big Foot Systems’ products and systems are quick and easy to install ensuring project cost and time clarity, thus reducing the need for complex, timeconsuming and expensive detailing.

WOMEN in the

ACR industry M I R E L L

R E I S S N E R

This month, the ACR Journal interviewed Mirell Reissner, Market Sector Expert Reefer Container and Railway for Bitzer for the Women in ACR column.

Education: Where did you study and what diploma/ degree did you gain?

I started my education as a refrigeration service technician at a company called Combitherm in Germany. After one year of work experience in this job, I went back to college to get my HVACR technician degree.

standing company was founded in 1934 and is today represented at 44 locations around the world. BITZER produces and distributes reciprocating, screw and scroll compressors as well as pressure vessels and condensing units. Approximately 3,400 employees work at BITZER and in 2015 its turnover was about 686 million euros.

you have to have a solid understanding of other technical branches as well. Electrics, for example. How are they connected to each other? This is the real challenge for me and also the reason why my job never gets boring. There’s always a new assignment waiting round the corner and further exciting projects to get immersed in.

Tell us about where you work now.

What attracted you to the industry?

What do you specialise in now? Or, what type of projects do you work on?

I have been working for BITZER since 1 January 2016, at the company’s headquarters in Sindelfingen, Germany.

The BITZER Group is the world’s largest independent manufacturer of refrigeration compressors. This long-

Women in ACR.indd 32

I’ve always loved technically challenging jobs. It was my father who introduced me to the refrigeration industry – he works in refrigeration, too. What fascinates me about HVACR is the big picture: Not only do you learn a lot about thermodynamics,

I support BITZER subsidiaries worldwide in technical questions about transport cooling and look after our OEM customers. I also assist in the rollout of new products like the new SPEEDLITE

scroll compressor. An important aspect of the job is to keep customers and our subsidiaries updated about changes they need to be aware of. All of this requires interfacing with different departments, such as manufacturing and dispatch, and organising and communicating with many people across the company and beyond.

What excites / interests you about the industry and your part in it now?

On the one hand, I’m fascinated by how refrigeration and air conditioning can develop and shape technology trends. On the other hand, I like to see the daily routine of my work: It is basically everywhere. I see foods in the supermarket and know that a compressor worked hard to keep these goods cool and fresh on the way. I see it in the train or bus, where people can enjoy pleasant temperatures. It’s still exciting for me to experience the direct influence my work has in the everyday life of all of us.

What would you say to other women who are considering coming into the ACR industry?

HVACR is indeed an industry dominated by men. But in my opinion, this shouldn’t play a significant role when choosing your career path. If someone asked me, I would say: Go for it, if you like a challenge.

Women in ACR.indd 33

It’s important not to lose the chance of succeeding in an area that interests you, especially as a woman. Of course, technical understanding plays a crucial role, but this applies for both men and women. It’s all a matter of interest and learning ability, not of gender.

Where do you see your career developing?

At BITZER, I started as Customer Support Engineer. I got new responsibilities after nine months in this job and extended my role as Market Sector Expert. I’ve worked as a Service Sales Engineer before, so I am pretty much specialised in service issues already. I want to take on more responsibility and grow and develop.

Especially regarding customer projects, where I can give personal on-site support.

What are the challenges of this industry?

From the technical point of view, it’s crucial to give the customers the best possible guidance. Compressors are technically complex products which require special knowledge in their handling. The customer has to understand the compressor he’s using in order to avoid mistakes which may affect the service life of the compressor.

This is where I come in and also one of the strengths of my department: It’s

important to train the customers well and to accompany their project from start to finish.

What are the benefits of being in your role?

I enjoy helping customers make a success of projects, so that they can in turn deliver for their own customers. It is satisfying and another big plus to take the protection of our environment into account by finding solutions for efficient refrigeration systems – especially in the transport sector, where you have to take specific challenges and issues into consideration.

What industry competitions or events have you participated in?

I support my team and company at trade fairs like the InnoTrans in Berlin, and of course Chillventa. I am very fortunate to work for a company which offers extensive training possibilities, so there’s always the chance to learn something new and to meet experienced industry insiders.

FETA SETS OUT HVACR

INDUSTRY AGENDA

FETA, the Federation of Environmental Trade Associations, set out key industry priorities in the week that the UK government stated when it aims to start taking the country out of the European Union.

R

efrigerant legislation, Indoor Air Quality (IAQ), commercial building running costs and the industry’s approach to the recent Brexit vote are at the top of FETA’s agenda.

F Gas regulations and A2L refrigerants

The ever-present topic of refrigerants in the cooling industry took centre stage as President of the British Refrigeration Association, John Smith (Technical Director with Beijer Ref), explained the landscape.

The F-Gas legislation is forcing manufacturers, contractors and end users to reconsider how they will implement changes to cooling systems which use refrigerants with low global warming potentials. Fluorocarbon refrigerants will soon be phased out, and the industry needs to adapt to using gases which have very low GWPs. Hydro-Fluoro Olefins (HFOs) have lower GWPs and less flammable (so-called ‘mildly flammable’ refrigerants) than existing Class 2 and Class 3 refrigerants. The new classification ‘A2L’ came into force to differentiate them from more flammable refrigerants. A2L refrigerants have a lower burning velocity. Nevertheless, the Health & Safety Executive (HSE) only recognises flammable or non-flammable refrigerants.

John Smith stated: “The F-Gas regulation will require the use of refrigerants with significantly lower GWP to meet phase down requirements. While HFO blends can be made non-flammable, there will always be a GWP penalty.

“The industry must face up to the need to make use of these fluids and

FETA.indd 35

understand the implications of their use.”

There is a big challenge with A2L refrigerants. It is not possible to retrofit them. Therefore the industry will need to use new systems to be able to use them.

John Smith pointed out that before A2L refrigerants become widely installed in cooling systems, because of the F-Gas legislation, there is some leeway for the industry. Current A1 refrigerants with low GWPs will bridge the gap between now and when the phase-out deadline arrives.

To help the industry get ready for using A2L refrigerants, FETA said that it would bring out new guidance within weeks. The association is working across its member organisations to anticipate the deadlines and challenges, and it is liaising with the HSE, AREA and EPEE to produce reports, help and guides.

John Smith added: “The industry needs clear guidance on the use of A2L refrigerants in the field. FETA recognises that this issue is pertinent to several associations and is interacting with other organisations while also discussing the subject with the HSE to understand its viewpoint.

“Put simply, the F-Gas Regulations will not work without the introduction of A2L refrigerants and the biggest challenge will be found in the air conditioning sector, where there is no non-flammable alternative to R410A.”

of legislation which focuses on how we sit at our desks, the brightness of our screens, or the temperature of the rooms we occupy.

However, we pay little attention to the quality of the air we breathe in our offices and homes.

Russell Beattie said: “IAQ is a broad topic, and it involves a number of Government departments.

Greater awareness can only be seen as a positive and FETA will continue to communicate the importance of IAQ to a wider audience.”

FETA is working with its members to update IAQ guidance and has recently published white papers through its Humidity Group.

Indoor Air Quality

FETA CEO, Russell Beattie, highlighted the challenge with indoor air quality and growing awareness of its importance.

Most news and legislation deals with the quality of air outside the buildings where we live and work. There is plenty

which almost inevitably leads to higher operating costs.”

To address the problem, the BCIA aims to help more people in the market about the importance of looking at the expense of the building over its lifetime. Malcolm pointed out a ratio of 10-80-10, where 10% of the lifetime costs of a building are to build, 80% of costs of the running costs, and 10% are decommissioning costs.

When the running costs are such a large proportion of a building’s lifetime costs, putting so much emphasis on the cost of building it seems short-sighted.

Being Balanced about Brexit Malcolm Anson

Addressing poor building performance

Malcolm Anson, president of the Building Controls Industry Association (BCIA) addressed the perennial challenge for the building services industry of raising the importance of the long-term cost of operating a building.

He began by saying: “The focus on capital costs for construction projects is leaving building owners and managers with properties that cost them more in terms of energy and maintenance in the long-term.”

This so-called ‘value engineering’ is when contractors are forced to strip out costs, such simple building controls, because of competition on price, which could save far more money for the building owners or occupants over the whole life of the building.

Malcolm added: “So often, BCIA members find that the removal of sensors for temperature or CO2, for example, means that heating and cooling are left to be operated manually

FETA.indd 36

Mike Nankivell, president of the Heat Pump Association, spoke on behalf of FETA about their approach to Brexit.

He called on the government to ‘think carefully’ about any changes it might consider as a result of the vote to leave the EU. FETA is keen to keep important links to groups in Europe concerned with product standards and regulations.

Russell Beattie added: “We urge the Government to think carefully before dismantling agreed policies and to consult with industry before making changes to the existing regulatory landscape.”

He continued: “This is not just about manufacturers exporting to the EU and keeping the same design criteria. Ultimately it is UK customers who would pay the price when it comes to nationally specific products.”

FETA has a vital role to play in keeping the heating and cooling industry’s interests in mind when it comes to Brexit.

Beattie concluded: “Our Trade Association links within Europe will be even more important following BREXIT, and we are keen to play our part in helping to strike the right balance. We’ve had almost half a century of treaties and agreements, covering thousands of different subjects – it is vital that the Government carefully considers the potential repercussions before making changes.”

ALL ABOUT DAIKIN APPLIED Having started in the HVAC industry as a contracts support engineer, before moving into sales and now as the product manager for Daikin Applied, I have witnessed a lot of changes over my 10 years within the industry, changes both within the company and the technologies that we put into the market and within the wider industry as a whole.

by James Henley, Product Manager – Chiller Specialist

“OUR IN-HOUSE EXPERIENCED PROJECT DELIVERY TEAM AND INFIELD SERVICE ENGINEERS ENSURE ALL PROJECTS ARE MANAGED FROM INCEPTION TO PRACTICAL

I

t is these changes that make Daikin Applied and the HVAC industry as a whole such a dynamic work environment with di�erent challenges every day and a future of potential growth throughout the sector.

As you are all probably aware, McQuay re-branded in April 2015 to Daikin Applied (UK) Ltd after being part of the Daikin Group for almost 10 years. Whilst, to many this was essentially just a change in name, to us at Daikin Applied it was much more.

We have continued with the customer focused core business values, which were at the heart of McQuay across key sectors of Chillers, AHU’s and our service & maintenance business, whilst embracing the change in culture that comes with the integration of Daikin and the major advantages of being part of the leading global HVAC supplier.

Daikin Applied .indd 41

COMPLETION ALL TO THE CLIENTS.”

NEW COOLING FOR ITALIAN

ICE CREAM BUSINESS A J & E Hall Fusion Commercial Condensing Unit is a key component in a new cooling system at a flourishing Italian ice cream manufacturing business. Gelato.Cool Ltd of Lincoln chose the JEH2-0400-L-3 unit for its walk-in freezer which stores gelato ice cream.

G

elato.Cool needed a new walk-in freezer to cope with the demands of a growing business. The 3.5 sq m freezer is racked out to handle the 4.5 litre Napoli tins in which the ice cream is held but the main challenge for the cooling system is keeping the temperature in the freezer at a constant -22°C for deep life storage.

Director of Gelato.Cool Mark Weston said:

“

Reliability and efficiency are important for us and the new Fusion unit works well. It is very quiet, hugely efficient and

JE HALL GELATO COOL.indd 42

represents good value for money. It keeps the freezer at -22°C all day and we are very happy. We manufacture the gelato at around -14°C and the ideal serving temperature is -17°C. Our new walk-in freezer allows us to store the gelato at a perfect temperature all year round.”

The freezer was designed and built

by Milby Coldrooms of East Goscote, Leicestershire. The company has installed Fusion units for ice cream vendors in the past and understand the demands of the industry. The J & E Hall unit, supplied by AFR Refrigeration of Wandsworth in London, is linked to a Maxkold LFJ/14 3.8L evaporator.

Italian Ice Cream Ideas

Milby Group Managing Director Nigel Rodgers said: It was a turn-key job for us and we came recommended by another customer in the ice cream industry. We were delighted to be offered the chance to build the new freezer room and we have to make sure that the equipment we use is reliable and does all it should.

The Fusion unit was our first choice.”

J & E Hall offers an extensive range of medium and low temperature reciprocating and scroll-housed commercial condensing units using R404a. Medium temperature scroll condensing units qualify for

Enhanced Capital Allowance. This Government scheme allows tax relief for businesses investing in energy efficient projects.

The acoustically-lined Fusion range houses a reciprocating compressor which is fitted with a compressor jacket to further reduce noise.

Mark Weston came up with the idea for the business after a long weekend in Florence two years ago. It was his curiosity to see where he could buy gelato ice cream when he returned to the UK that led him to set up the venture.

The company employs five people which includes his mother Carol, sister Sarah and daughter Robyn.

At Gelato.Cool all the ice cream is made in-house with specially imported machinery from Italy. The company has more than 160 Napoli tins of ice cream in storage containing around 1000 litres of ice cream.

Production is demand driven and gelato is manufactured in advance

of the summer months to cope with the peak season.

Increasing Interest in Gelatarias

This summer, with its warm weather, proved to be a particularly good year for business. Typically, around 200 to 300 litres of ice cream is manufactured by the firm a week.

Gelato.Cool supplies ice cream to restaurants, cafes, bars and pubs in the Lincoln area. “Many of our customers are Italians who run patisseries and coffee shops,” Mark explained. “We also do quite a lot of business in the area serving at festivals and outdoor events.

Gelaterias are very much in their infancy in the UK but in Italy you are likely to find one every 50 yards or so in the main street.”

The most popular flavour manufactured by Gelato.Cool is jaffa cake – a combination of chocolate and orange. “This may come as a surprise to some but there are no limits to the flavours we can produce,” added Mark.

“We buy all our own fruit and pulp it to produce fresh fruit sorbets too – including mango, strawberry and orange flavours. Peach and Prosecco is a popular sorbet and we also supply the Bounty, a chocolate and coconut combination. Think of a flavour and we can pretty much produce it.”

WINNERS VISIT LU-VE IN ITALY The winners of the 2015 ACR Trainee of the Year Awards visited the LU-VE heat exchanger factory in Milan in September. ACR Journal editor, Will Hawkins, went with the group to see how LU-VE, which celebrates its 30th anniversary this year, operates.

T

he ever-popular awards to find and celebrate the best talent coming up through the air conditioning and refrigeration industry's training centres came to a climax in mid-September. The three winners and their employers flew out to Milan to spend two days with LU-VE as part of their prize.

Steve and Christina Taliadoros from LUVE UK organised and sponsored the prize visit to this innovative manufacturer's heart on the outskirts of Milan, northern Italy. The group included winner, Joshua Lincoln from Adcock, and highly commended winners Peter Coupe from DD Cooling and Christopher Lake from JD Cooling Systems. Also, their employers joined us, namely Stuart Dougal, Adcock and Dave Dobson, DD Cooling. Jacinta Caden from TECNAIR joined us too.

Data Centre Cooling

The group landed in the heat of Italy's late summer to be whisked off to LU-VE Group headquarters and factory a few miles north-west of Milan. There, we enjoyed a delicious, traditional Italian lunch in the staff restaurant (including wine - Who were we to turn it down?) and met some of the leading members of the team.

After lunch and a quick presentation, the group visited the data centre cooling solutions factory known under the brand name TECNAIR. LU-VE bought the company some years ago. The family that started the business is still heavily involved in the firm. TECNAIR is a small but growing brand in the UK market, as well as in the niche sector of ventilation for hospital theatres.

Nevertheless, LU-VE has their production line packed with units ready for customers around the world, and their expert team is passionate about creating its

LU-VE P44.indd 44

Chris, Josh and Pete

high-quality products in a growing market.

Next stop was the centre of Milan for dinner where we ate in a local jazz café, and Steve Taliadoros showed us the latest in Milanese, minimalist hat fashion. A few more beers later, we headed back for an early night (well, for some of us that was the case!).

Heat exchangers in the making

The next day, we returned to the factory to learn about the extensive heat exchanger business. LU-VE's production line is impressive. Any decent manufacturer makes its products using 'Lean' methods, which ensure quality while being as efficient as possible. LU-VE is no exception. But, it's the detail which impresses you most. For instance, they still braze by hand. When asked why Steve said it was because robots can't compete with humans when it comes to precise brazing.

Steve showed almost every inch of the LU-VE factory, and we must have walked several miles watching raw materials become finished products. Their speed of production is impressive, but the range of goods which they produce for their customers is remarkable too.

But, the aspect of LU-VE which is the most notable, yet least tangible, is the sense of teamwork and belonging which each employee that spoke to us showed. It means that LU-VE makes great products because their team cares. When you care, people like working with you. No wonder LU-VE is celebrating 30 years of success this year.

The ACR Trainee of the Year Award winners all said they had learnt a lot about LU-VE and how they make their heat exchangers. Another wise investment from the company in bringing people into their family.

HEAT PUMPS TODAY CELEBRATED

WITH DAIKIN UK Daikin UK celebrated a decade of its Daikin Altherma heat pump range and the success of its KEY Associate and Partner scheme at an exclusive event in Birmingham on the 8th September.

T

he conference featured market insights from Senior Analyst at Delta-ee, Steven Ashurst and an interactive polling session to gain market feedback from KEY installers, so it provided a valuable opportunity to share views on the future direction of the heating and renewables market.

Launch of the heat pump

Since its launch in 2006, more than 350,000 customers across Europe have installed a Daikin Altherma domestic renewable heat pump system, producing 12,000 GWh of renewable energy and resulting in an estimated 1.5 million tons reduction in CO2 emissions.

Integral to this success has been investment in ongoing product innovation and the formation of the Daikin KEY Installer Scheme. Offering free product training, extended warranties and dedicated technical advice, plus a wide range of business rewards and co-branded

marketing materials, the Daikin KEY Installer Scheme is designed to give members the very best support within the renewable heating sector.

Heat pump futures

In his presentation, Steven Ashurst outlined a pathway for the future growth for the domestic heat pump market in the UK. Drawing on favourable drivers such as increasing awareness of heat pump technology and the electrification of heat remaining a strong priority for Government, Steven forecasted that the number of installed domestic renewable heat pumps in the UK could reach 27,000 by 2018, growing to 90,000 in 2025.

Innovation accelerated

Reflecting on a decade of Daikin renewable heat pumps, Martin Krutz said: “In the last 10 years, the pace of innovation within the renewable heating sector has significantly accelerated. In this time, Daikin has been at the apex of this innovation, continually

improving and expanding its portfolio of renewable heating solutions and being the very first company to launch a true Hybrid solution in 2013.”

LANDMARK RENEWABLE HEATING AND PASSIVE COOLING FOR RAGT SEEDS

Renewable heating expert Finn Geotherm, has completed a landmark installation for leading European agricultural plant breeder RAGT Seeds in Cambridgeshire, to deliver both heat and passive cooling with significant energy savings.

R

AGT’s initial brief was to reduce the heating costs for its six glasshouses, which are used for developing new crops. LPG had previously been used to heat the glasshouses which, with a U value of around six, meant the boiler was in constant use in winter, leading to issues with fuel supply and heat distribution as the system couldn’t keep up with the heat being generated.

RAGT needed a new system to work with its existing grow tubes.

Kit

Finn Geotherm installed three Lämpöässä T120 ground source heat pumps linked to three Akvanti 2400litre thermal stores with a network of 21,000metres of collector loop. Controlled using Trend building management, the 350kW ground source heat pump totally replaces RAGT’s previous LPG system.

While specifying ground source for RAGT’s heat requirements, Finn Geotherm identi�ed an opportunity to utilise the new system to deliver air circulation and cooling. This would ensure a constant temperature all year round for crops to thrive in. Glasshouses had been known to reach 45°C (compared to the target temperature of 21-22°C) and

low level techniques, such as painting windows and using fans, were ine�ective.

However, the implementation of a cooling system had to be very carefully developed to ensure the system did not impact negatively on the Renewable Heat Incentive (RHI) available to RAGT Seeds for the ground source heat pump installation.

Lower energy costs

Steve Brown, Operations and Production Manager, RAGT Seeds, said: “The ground source heat pump system is delivering everything we hoped at a lower energy cost than expected. The quality of workmanship throughout the job was exceptional with obvious care and pride being put into every aspect of the installation. We fully expect the system to make a huge contribution to our energy e�ciency and to improve our glasshouse productivity, as well as dramatically reducing our emissions and enabling a reduced use of chemical fungicides. Gaining these bene�ts, with the expectation of signi�cant RHI income over the next 20 years, makes this a very successful project which we hope to replicate at other sites.”

Passive Cooling

Finn Geotherm’s team of experts devised a bespoke passive cooling system to circulate air at ambient ground temperature from the ground loop. Cool air is circulated through 24 Jaga AVS fan coil units (four per glasshouse) using a control system which activates if the temperature increases by 1°C from target.

Passive cooling delivers the reduced temperatures needed by RAGT in summer using minimal energy. Air circulation from the cooling system has made a signi�cant impact too, providing a ‘gentle summer breeze’ in the glasshouses. Along with the better regulated temperature, RAGT is also now enjoying enhanced plant growth and expects to reduce chemical inputs.

People in glasshouses…

Guy Ransom, Commercial Director at Finn Geotherm, said: “The installation at RAGT Seeds has not only revolutionised the way in which the company heats its glasshouses.

Ground Source Heat Pump

Case study: Wanstead Eco Home This eco project proves that even in the city you can have your own green haven.

Summary

A

rchitect Jason Harris was looking for a renewable heating system to complement an innovative eco home he was building in East London. Land area was restricted due to the urban nature of the site, but thanks to a unique borehole drilling method used by Ground Sun, a Kensa ground source heat pump was successfully installed.

Background

In 2015 Jason Harris, Director of East London based architectural practice, T-Space, designed and built an ultra-modern, eco-friendly home. He wanted the 550m² house to be as selfsufficient as possible and was keen to

KENSA .indd 50

Key Facts 550m² new-build eco home Kensa 20kW Twin Compact ground source heat pump Underfloor heating and polished concrete floors Solar thermal providing additional hot water Heat recovery ventilation system Low consumption LED lighting and appliances Eligible for Domestic Renewable Heat Incentive RHI.

install a renewable heating system rather than using the gas network.

He approached Kensa partner installer Ground Sun who suggested that a ground source heat pump would provide a sustainable and efficient source of heating and hot water. Ground Sun also

advised that the ground source heat pump installation would be eligible for the Domestic Renewable Heat Incentive (RHI), earning regular quarterly payments from the Government for seven years to more than offset the cost of the initial investment.

Ground Sun specified a 20kW Kensa Twin Compact ground source heat pump. Brian Connell, Director of Ground Sun said: “Kensa manufactures the highest output single phase ground source heat pumps on the market, which is really useful for large domestic jobs such as this one. Also, Ground Sun enjoys a good working relationship with Kensa and appreciate the support offered during the installation process.”

The heat pump is installed in a

basement plant room. Smart energy meters complement the system and controls are kept to a minimum, consisting of a time clock and just four thermostat zones. It was felt preferable that the heat pump be allowed to run for longer periods at a lower level to achieve optimal e�ciency, instead of cycling on and o� with the demands of multiple controls. The �ne tuning and long term balancing for each room is done by hand at the manifold.

Jason Harris commented: “This project centred more on achieving the optimal outcome than a fast completion.”

As the house is located in an urban part of East London land area was limited, and so it was determined that boreholes would be the most e�ective form of ground array.

However, as the site was accessible only via a very narrow lane, impassable by standard drilling rigs, Ground Sun utilised a radial drilling rig which could comfortably cope with the restricted access.

The radial rig is a three tonne drilling rig and has the added advantage that the hydraulic/ engine section can be separated from the drilling mat and sited away from the drilling operation thereby

KENSA .indd 51

keeping noise and disruption away from neighbours. The innovative radial drilling method is adapted from techniques used to create utility networks for powerlines and gas mains.

A main drill chamber acted as an access point from which separate boreholes were drilled. By drilling out at 65° and 45° angles, eight 50m long radial boreholes were able to be installed on site. This reduced the amount of excavation that was required and meant that the installation caused a minimum amount of disruption.

The house has a unique design which grew out of the planning constraints of the site; the planted green walls are intended to blend into the surrounding tree cover, alongside large glazed windows which encase a central internal courtyard. As the project was a new build, Ground Sun was able to liaise closely with the architect and ensure that the installation �tted in conveniently with the build programme.

Despite its size, the house was designed with as small a carbon footprint as possible, being highly insulated and predominantly of timber construction.

The property has under�oor heating installed throughout, laid under polished concrete �oors to provide thermal mass and an e�cient way of emitting heat which works very well with the ground source heat pump. Solar thermal technology will provide additional hot water capacity; a heat recovery unit provides a whole-house ventilation system and low energy consumption LED lighting and appliances combine to give this stunning property maximum energy e�ciency.

The heat pump has been running for a year so far and the owners are very happy with how it is performing.

Each property has a local touch pad controller, under�oor heating and traditional wet radiators. The system has the capacity to run 12 showers simultaneously, including high volume rain showers, without losing pressure or running out of hot water.

To maximise the energy and performance e�ciency the heat pumps run on a sequential basis allowing each heat pump to operate for the same amount of time and facilitate the peaks and troughs of the demand.

The main house would be altered at a later date. The barn would remain almost as it was, and a garage would be converted to create a one bedroom apartment with laundry facilities.

Air source heat pump solution

Following further consultative meetings Steve dale, MD of e2 and Russ Langthorne, Commercial Director, presented a concept that consisted of a remote plant room housing Daikin air source heat pumps, a bu�er vessel, boosted pressurised hot and cold water, a water softener, central controls and a standby generator.

The team sites the equipment servicing each property from a common plant room which is 85 metres away from the principal home. The air source heat pumps consisted of six high temperature Altherma out door units and six 16KW indoor units. The team also installed a 300 litre bu�er vessel. e2 recommended under�oor heating to be installed where

Following more consultations and �ne tuning e2 and the client agreed on the concept and started the project.

The net result has seen the work completed within a �ve month programme. Each property has a plentiful supply of instant pressurised hot water, pressurised softened cold

Due to the success of creating a ‘home grown’ engineer base and through their work within both the local community and local secondary education academy, e2 has recently employed another 16 year old school leaver who will be enrolling for his apprenticeship later this month and starting his path to becoming an NVQ quali�ed engineer.

The donation is part of a major three-year investment in apprenticeships that will see the same amount pledged to every major college in the UK that provides apprentice refrigeration courses.

“Service engineers are the lifeblood of our industry and we want to support the next generation of apprentices with the very best equipment available,” said Barry Lea, chairman of Advanced Engineering.

“We’ve donated 10 free recovery machines from the worldrenowned Promax family to Eastleigh College, including six of the bestselling Minimax models and four of the new top-of-the-line RG6-E refrigerant recovery machines.”

The charitable donation comes at a crucial time for refrigeration training providers; with the new A2L refrigerants starting to come in, engineers need new equipment which is able to safely handle the new mildly flammable refrigerants.

Leading air conditioning installation specialist Coolair Equipment Ltd is celebrating after scooping a top national award for charity fundraising.

The company, which has offices in Manchester, the Midlands and Kent, raised no less than £90,000 from a year-long campaign for Challenge Cancer UK which included a 300-mile cycle ride through South East Asia.

The charity presented Coolair with its first-ever Outstanding Contribution Award in appreciation of the biggest donation from any business it had ever worked with.

Regional Director Neil Gibbard, who organised the campaign, received the glass star trophy from Challenge Cancer UK Founder Mark Roberts on behalf of the company. He was also made a Corporate Ambassador for the charity.

Coolair teamed up with one of its biggest suppliers and business partners, Mitsubishi Electric Air Conditioning Systems, to recruit and lead a team of 18 staff and customers on an epic six-day bike ride from Saigon in Vietnam to Angkor Wat in Cambodia.

Coolair staff chose Challenge Cancer UK as the adopted charity for their 35th anniversary year after they were moved to learn that it distributes its funds to cancer charities throughout the journey of cancer from awareness and prevention to research and respite.

Challenge Cancer UK raises funds for cancer awareness, prevention and research, as well as patient treatment care and support for those affected by cancer. The Manchester-based charity can be reached at www.challengecanceruk.org (Tel: 0161 771 2040).

₀ Advanced Engineering appoints new Sales Director

₀ Conex Bänninger recruit to build the North East region

₀ Ebac appoints International Sales Manager

Advanced Engineering, the UK distributor manufacturer of cleaning chemicals for the air conditioning and refrigeration, has appointed a new sales director: John Barraclough.

A highly experienced sales professional, John joins Advanced from one of the world’s leading valve actuation companies where he was responsible for an international sales and support team across Europe, the Middle East and Africa.

John has a background in electronic engineering, initially completing an apprenticeship and gaining an HNC in Electronic Engineering. His career has seen him hold roles of ever increasing responsibility in the areas of engineering, customer support, technical support, internal and external sales and finally sales management.

Conex Bänninger, one of the world’s leading manufacturer of valves and pipe-fittings, has shown its intent within both the commercial and domestic sectors in the North of England by appointing Zoe Mackay to the position of Regional Specification Sales Manager for the North East.

Stationed within the Yorkshire and Humberside counties, Zoe joined IBP Group, bringing with her a wealth of relevant experience on both the manufacturer and merchant side, having spent the two years as a specification manager and subsequently four years as a commercial sales manager for a merchant chain.

This ability to see both sides of the trade coin will be invaluable to Conex Bänninger, as Zoe’s main responsibility will be to develop business with both Commercial and Domestic HEVAC contractors. The company looks to improve its strong market position, supply chain delivery and service excellence to increase market share in the North East.

Ebac has appointed an international sales manager for its water cooler and dehumidifier divisions.

Tom Teigeler, an experienced sales professional and business specialist with more than 15 years of international expertise, will be based in Belgium, to help North East-based Ebac, expand its market in two key areas: business to business sales of water coolers and business to consumer sales of its state of the art dehumidifiers.

Tom started his career in consumer electronics, as an export manager for a Hong Kong – Israeli trading company, in cordless telephone handsets, in 1996.

These were marketed in the whole of Europe, mainly to telecom operators and wholesalers. Later he joined a Belgian cable operator as CPE marketing manager, setting up a full product portfolio.

In 2003 he joined a Belgian consumer electronics manufacturer, helping them to grow from a local to a well-known European brand. He established local sales offices in Eastern Europe, Poland and Russia and an assembly and refurbishing plant in Slovakia.

Richard Harden, Sales Director for Building Services, will take over the role of Managing Director of Wilo UK and CPL from 1st October. Richard joined Wilo UK in December 2000 and became Regional Sales Manager in September 2007 followed by the role of Commercial Manager and later Sales Director. Here he worked closely alongside Gary Mannus playing an important part in the growth of Wilo UK.

Kurt Brown has joined the Wilo UK marketing team as Marketing Assistant UK/IE. Formerly working in the recruitment field, and in project and account management, Kurt is a Marketing Graduate, having studied at Staffordshire University.

He works closely with Morgan Warren-Ross, the new marketing manager at the leading pump and pumping system manufacturer: “I’m delighted to have joined Wilo and am enjoying my role working for a major player in the pumps sector.

It’s been eye-opening to get involved in the many areas of work Wilo covers – in the heating and air conditioning, industrial and water management sectors.” In his spare time Kurt is a keen football fan and bravely supports Aston Villa.
