The last month has been interesting. Since commenting on wanting to hear more about combined heating and cooling solutions, I have been inundated with calls and emails on the topic. As a result, I learnt a lot about the challenges in the market including convincing and educating customers on the benefits of combined heating and cooling systems. It seems like an obvious solution to use the heat rejected from, say, a chiller and reuse it to provide hot water in the same building. But, it has surprised me how customers were not aware that they could become much more efficient by just using the laws of physics. i.e. you cannot create or destroy energy. It just moves from one form to another. In other words, why spend a lot of money cooling something down and just pump the heat into the atmosphere; and then, spend more money on a different plant to heat another part of your building up. It does not make sense when you already have the heat available being rejected from your cooling system. Yes, there are some locations where a combined system is not practical. But, I have listened to experts in the field tell me about combined heating and cooling solutions which are paying for themselves in under two years. In a time when trying to increase your profits by increasing your prices is next to impossible, surely this approach is one of the best ways to help your customers make more money? Don’t limit your thinking. Heating and cooling are subject to the same laws of physics. Use them to your benefit.

Bitzer Owner and CEO Dies
Green Point Begins Remanufacturing Other Compressor Makes Green Point, Bitzer’s compressor remanufacturing arm, today announced that it will soon include other manufacturer’s products.
Compressor manufacturer, The Bitzer Group, announced that its owner and CEO, Peter Schaufler, passed away aged 74. Senator Schaufler took over in 1979 and immediately widened the focus of the German company to more international markets. Schaufler turned Bitzer into a global business, driving innovation in the air conditioning and refrigeration industry. Schalufer grew the business to be 50 times the size it was when he started. Bitzer now has 3,400 employees in over 90 countries, and turns over €657 million (circa £463 million) a year. Peter Schaufler had great entrepreneurial drive founding, for example, a joint venture with a Chinese company in 1994 before the country’s economy took off. His values of hard work, ingenuity and high quality characterised the era, which are now embedded in Bitzer’s business. Peter Schaufler always looked ahead and rose to the challeneges, which enabled him to find new markets and bring new products, such as screw compressors in 1983 and scroll compressors in 2002. Germany recognised Peter Schaufler’s contributions to culture and science in 2010 when it awarded him the Cross of the Order of Merit of the Federal Republic of Germany. Senator Schaufler’s family held a quiet funeral ceremony recently.
When Green Point launched in the UK last year, they focused only on Bitzer compressors. The company will begin remanufacturing on non-Bitzer compressors from September 2015. Makes include Bock, Carrier, Copeland and Trane. Green Point UK’s managing director, Will Pribyl said: “The aim always was to begin by remanufacturing Bitzer compressors. Having successfully established the business, and with a growing customer base, we are now widening the offer to include machines from other manufacturers.” The company recently appointed a new ‘Remanufacture Technician’, France Bootun, to cope with the expansion in the UK.
Refrigerants Market Expected to be over £13 billion by 2020 The market for fluorocarbon, inorganic, and hydrocarbon refrigerants is expected to reach £13 billion (US$21 billion) by 2020, according to market research company MarketsandMarkets in a new report. The latest report from the researchers focuses on refrigerants in domestic, commercial, transportation,
06_NEWS_new.indd 6
industrial, stationary air conditioning, chillers, and mobile air conditioning sectors. They anticipate that the refrigerant market will grow by 6% between now and 2020. Unsurprisingly, the refrigerants market was dominated by stationary air conditioning markets until recently. But, growth in the construction industry and in the food, and pharmaceutical industries increased has recently changed the balance.

BRITISH REFRIGERATION ASSOCIATION
LAUNCHES NEW REFRIGERANT GUIDE
The BRA (British Refrigeration Association) launched its new refrigerant guide at the British Library in September. The new guide from the BRA, named ‘Putting into Use Replacement Refrigerants (PURR)’, helps ACR industry professionals understand the impact of the F-Gas regulation on them and their customers. It also helps them understand how to make a plan for their business in response to the changes. BRA President, Mike Lawrence, said: “Our aim is to help people find an appropriate response to the F-gas legislation that has come from the EU. The PURR report highlights the very real challenges that clients in the sectors, such as retail refrigeration, will face as a result of F-Gas.” The 23-page PURR is available to download for free on the BRA section of the FETA website: www.feta.co.uk/ associations/bra/publications
NAPIT LAUNCHES ONLINE NEW INSTALLER FORUM
The trade association for heating, ventilation, air conditioning, plumbing and renewable energy installers, NAPIT, has a new online forum for its members. NAPIT (National Association of Professional Inspectors and Testers) launched the new online community to help its trades-person members to get in touch with each other more easily and to find expert support. The new forum follows on from the new NAPIT website and selfcertification software. The new forum provides the following member benefits: • A new user interface to help members navigate the site more easily. • An ‘Ask NAPIT’ section where members can ask questions directly to the support team. • A resource page to quickly find useful information, services and updates. • A marketplace message board to help make selling and buying trade kit easier.

HRP CHAIRMAN KINGSLEY CURTIS DIES HRP, the air conditioning and refrigeration wholesaler, announced that its Chairman, Kingsley Curtis, died recently after a long battle with cancer. In 1964 Kingsley became managing director of HRP when his father, who set up the business in 1945, died. Before he took over as MD, Kinglsey had trained in both engineering and sales. He built the air conditioning and refrigeration wholesale business up to be one of the UK’s leading firms in the sector. Many of the industry’s largest manufacturer’s work with HRP as a chosen distribution partner. Kingsley was still involved in the business before he passed away, including a recent national tour of HRP’s chain of service centres to celebrate their 70th anniversary. Group Managing Director, Mandy Pilgrim stated: “HRP has always been a family Company, much noted for its long serving employees. Kingsley has touched a great many lives in his long career and his loss will be deeply felt by many, both in HRP and the wider industry.” HRP’s management team and shareholders are confident that the business will continue to develop and serve its customers in the long-term. Beijer Ref’s CEO, Per Bertland, HRP’s largest shareholder outside of the Curtis family said: “Kingsley has built a sound and exciting business. We look forward to further development of HRP and stand behind the management at this sad time.”
CHEMOURS MAKES R-499A AND R-513A AVAILABLE IN THE USA Chemours, made two new refrigerants available to the US market, namely R-499A and R-513A, the company announced recently. Companies use the refrigerants in commercial refrigeration and mobile air conditioning applications, as well as other applications. The US Environmental Protection Agency approved R-499A and R-513A under its Significant New Alternatives Policy (SNAP) Program because of the new refrigerants’ ‘GWP’. Chemours is increasing its capacity to make new, low-GWP refrigerants as demand for environmentally friendly alternatives from manufacturers, contractors and end users increases. Existing refrigerants, such as R-404A, 507 and 134a, have significantly higher GWPs than the new generation of chemicals. For example, R-499A has a GWP 67% lower than R-404A. R-513A has a GWP which is 56% lower than R-134a.

he refrigeration, Air Conditioning and Heat Pumps (RACHP) industry underpins everything we do. Refrigeration reaches in to vast range of fields, that we all in counter in our everyday lives. For example, without it the food supply would still be seasonal and limited to locally produced non-consumable items; data centres would not work; comfortable living conditions and certain medical advancements would be impossible.
RACHP account for 19% of UK electricity demand or around 10% of total greenhouse gas (GHG) emissions. Last month at an EU meeting in Paris, the EU agreed to intensify reductions in carbon emission further from 2020 to 2030. This will include a further 40% GHG reduction, through much greater use of renewable technologies and a massive increase in energy efficiency. As a big GHG emitter and electricity user, the RACHP industry will be at the forefront adopting different ways of reducing the energy use and carbon emission for RACHP, such as utilising and developing efficient innovative and low carbon technologies. Modern refrigeration is almost entirely based on a compression and expansion refrigeration cycle. Vapour compression refrigeration is a mature, reliable and relatively low cost technology. Over the years, the design of components and equipment of refrigeration systems, such as heat exchangers, compressors, fans, pumps, refrigerants and expansion valves were considerably improved due to extended research and developmental efforts. Anticipated improvements,
however, are incremental since modern refrigeration is already near its fundamental limit of energy efficiency. However, vapour compression is not the only cooling technology available. There are many many others. These are shown in figure 1 below included here are technologies that maybe familiar including absorption and adsorption refrigeration, however, there are some more obscure technologies such as Electrocalorics and thermoacoustics. In a series of articles SIRACH will review individual heating and cooling technologies and simply describe how they work, who has been developing them. The potential benefits of application and the challenges in bringing to market. Next month we will describe Magnetic refrigeration.

200 STUDENTS JOIN THE INSTITUTE OF REFRIGERATION for speed-networking!
The 24th International Institute of Refrigeration International Congress of Refrigeration was held in August 2015 in Yokohama, Japan and attracted 1200 delegates from 55 countries including more than 200 students. The importance to the future of the industry of these young engineers was highlighted with a special reception for Students and Young Researchers organised as a networking event for the next generation of refrigeration professionals to meet leading experts from the sector. Dubbed “speed networking” the session was jointly organised by the UK’s Institute of Refrigeration, International Institute of Refrigeration (IR) and the Japanese hosts JSARE.
BEING A YOUNG RESEARCHER
Dr Ina Colombo, Deputy Director of the IIR and an IOR Member, welcomed the students and shared her own experiences of being a young researcher at International Conferences and how her nervousness had stopped
IOR_NEW.indd 10
her approaching well know people from within the industry. This was the inspiration for founding the Institute of Refrigeration’s Young Engineers Network in the UK and the development of the international networking sessions. These networking sessions are now a popular and regular part of both IOR and IIR conferences and the Institute of Refrigeration regularly hold sessions at universities and colleges around UK.
CONFERENCE NETWORKING
Catarina Marques, current chairman of the IOR’s UK Young Engineers Network, then managed the networking session, during which 210 students from 26 countries met with more than 40 senior industry representatives. Amongst those attending were IIR’s Gustav Lorentzen Medal Winner Dr Reinhard Radermacher (USA), Dr Andy Pearson (UK), Dr Pega Hrnjak (USA), Prof Ruzhu Wang (China), Prof Koichi Watanabe (Japan), Dr Philippe Lebrun (Switzerland), Prof Don Cleland (New Zealand), Prof Alain Lebail (France) and many more. The principal of the speed networking is for the young researchers to each prepare one question and then to meet with the RAC experts in small groups for a short period of time. There is lively debate and an exchange of ideas. The networking is a valuable experience for all with both students and experts finding the
sometimes unexpected discussion topics thought provoking and leading to discussions that are both challenging and informative. Prof Graeme Maidment, President of the Institute of Refrigeration, remarked: “I am always delighted to take part in the student events, it is very encouraging to see that the next generation of engineers and researchers are as bright and innovative as we need them to be. I will do everything I can to encourage them to stay in refrigeration as this sector needs them.” The young researchers also found the event beneficial, one student commented “I never thought these people would be interested in what I have to say, now I know that I can introduce myself to them and they will listen.” The Institute of Refrigeration will be following up this success with a series of Young Engineers’ Networking Events in the UK this year. On the 1st October the network will take part in the Sustainability Innovation Network (SIRACH) meeting at the University of Newcastle. The free event will explore networks for heating and cooling. Further events are planned with students at the University of Birmingham and Brunel University. Plans are also underway for another international student event at the 12th IIR Gustav Lorentzen Natural Working Fluids Conference in Edinburgh in August 2016. If your business employs any students or researchers who would like to join the network and come to future events please contact us at www.ior.org.uk/ youngengineers.

STANDARDS SIGNPOST

POWERFUL TOOLS FOR BETTER RAC SYSTEMS By Stephen Benton and Jane Gartshore of Cool Concerns Ltd A standard is an agreed way of doing things. They cover systems, products, components and procedures and are the distilled wisdom of experts with up to date knowledge of their subject and their industry’s needs. If all refrigeration, air conditioning and heat pump systems complied with relevant standards we would have systems which are safer, more reliable, more energy efficient, leak less and are future proof. But they are often viewed as complicated and many people are unaware of their relevance, importance and value.
A LEGAL REQUIREMENT? Standards are voluntary, but are there to make life simpler, for example to design and install better RAC systems. Many standards
are harmonised with European directives. They are the best and simplest method of complying with these regulations. In our industry this includes, for example, the Pressure Equipment Directive. EN 378-2:2008+A2:2012 Annex ZA shows the relationship between the standard and the essential safety requirements of the PED. Compliance with EN378 is the simplest way of compliance with most of the requirements of the PED.
WHAT’S IN A STANDARD? Standards follow a standard format – as you would expect! The standard usually includes: • Foreword – published date, standards which it supersedes; • Introduction – background information;
• Scope – what the standard covers and does not cover; • References – other standards and documents referenced; • Terms and definitions – an accurate jargon buster; • Clauses and annexes providing the information; • Annex Z – relationship between the standard and essential requirements of various directives. Some standards are split into several parts to make them more manageable and cost effective (they can be bought individually). Standards exist at national, European and international level: BS – British Standard EN – European Standard ISO and IEC – International Standards.
KEEPING STANDARDS RELEVANT AND UP TO DATE Technical committees are responsible for maintaining standards. For complex or large standards the committee is split into specialist working groups. The groups comprise experts who are usually nominated by industry bodies such as the Institute of Refrigeration or by other organisations with an interest in the standard, such as manufacturers or environmental groups. Revisions typically occur over a five year period to ensure Continued on page 14

Continued from page 12
standards remain relevant to industry and are up to date with regulations, technology and best practice. Outside of the main revision amendments are made. Always make sure you are referring to the current up to date standard and that it has not been superseded, the best way to check is using the BSI website shop: http://shop.bsigroup.com/

Title
What we like about it
EN 378 parts 1 to 4
Refrigerating systems and heat pumps – Safety and environmental requirements
This is THE standard for most refrigeration systems. Systems designed, installed, operated and maintained to this standard are safe, reliable and efficient. Highlights include: • Basic refrigerant information; • PS and over pressure protection; • Maximum refrigerant charge sizes; • Pipe work design and joint types; • Requirements for machine rooms; • Refrigerant leak detection systems; • Repair of systems using flammable refrigerant.
ISO 5149 Part 1 to 4
Refrigerating systems and heat pumps – Safety and environmental requirements
If you are working outside Europe this is the standard for you – it is very similar in scope to EN378.
ISO 817
Refrigerants — Designation and safety classification
Refrigerants — Designation and safety classification The title says it all, and it has just been updated.
EN 60335
Household & similar electrical appliances
EN60335 has over 100 parts! Although the title suggests they are not relevant to commercial refrigeration actually some of them are. They cover, for example, air conditioners, refrigerating appliances, vending machines and motor compressors and are product standards. For example they are relevant for appliances which use up to 150 g hydrocarbon refrigerant. For larger charge sizes EN378 would be the applicable standard.
EN 60079
Explosive atmospheres
Again, a multi part standard, some of which are applicable to hydrocarbon refrigerant systems. We use this standard for area classification (leak simulation testing to determine the extent of a flammable zone in the event of a leak) and for the specification of Ex electrical components.
OUR FAVOURITE STANDARDS We love standards at Cool Concerns! Stephen Benton is on the review committee for EN378 for example (the revision is now almost complete and should be issued next year, when the cycle will start again). But we also recognise how important they are to the industry, and how much easier our job is when we have standards to follow.

hese days almost everyone has a smartphone of some description and most manufacturers are aware of this and are developing Apps that aim to help engineers answer queries or get the information they need at their fingertips whilst they are out in ‘the field’, working on live projects.
Whether it’s a list of fault codes or access to wiring diagrams, product information sheets, or heat load calculators, you could be forgiven for thinking that the day is fast approaching when there will be no more need for a classroom-type environment for real ‘hands-on’ learning. And you couldn’t be more wrong in the opinion of this engineer and trainer. Apps and downloadable information can be incredibly useful when you are on a job, and can save the time needed to call a helpline (although I do recommend speaking to a real person from time to time!). They can allow you to get the answer to a straightforward question, quickly and concisely, but they should only ever be seen as another ‘tool’ in the toolbox. There simply isn’t an App anywhere yet invented that can
replace the knowledge gained in the training centres and colleges, and backed up with on the job experience working with qualified colleagues. There is real value in sharing knowledge and gaining from others that cannot be gained in any other way than face to face. That is why manufacturers such as Mitsubishi Electric run so many training courses, and why we have invested in training centres in our regional offices, and why we are linking with more and more colleges, and why we have developed a National Apprenticeship Scheme with our partners. Like any other piece of modern equipment, air conditioning is very sophisticated and, once correctly set up, often includes self-diagnostics that will ensure it continues to run efficiently and effectively between annual maintenance checks. But you do need to know how to set the thing up correctly in the first place and this is simply not something that can be done only on a smart phone.

INSTALLATION
October 2015
Installation – process and pitfalls In a series of articles, the experienced Fujitsu technical team takes you through the process and pitfalls of an air conditioning project from start to after sales. Here Colin Goode, Fujitsu’s product and specification manager, looks at the first steps. FIRST STEPS The first step after receiving an enquiry for most air conditioning projects, in an existing building, is to undertake a site survey and meet with the prospective client. For a brand new building that is not yet out of the ground, you can only work from drawings. However, since the large majority of installations are for existing buildings, we will assume, for the purposes of this article, that the application is a two-story office building, with approximately 160m2 per floor and multiple segregated cellular offices and open plan areas. From experience, I have found
that an important factor in any successful air conditioning design and installation is managing the customers’ expectations. Yes they can have an ‘all singing and dancing’ system with all the ‘bells and whistles’, but do they have the budget for it? When they first make an enquiry, most customers do not have a clue about how much air conditioning costs, so it is important to establish what their budget is. Some customers may be willing to discuss this but others will not, especially if they have already had a price from someone else and are shopping around for a better deal. Failing this, try to give them a ballpark price early on to establish whether it’s worth them, or you, proceeding any further. Assuming this all goes well, the next step is to carry out a site survey during which the following information needs to be gathered: • Size of room(s) – internal /external walls and orientation. • Number of people in each room. • Windows – sizes, type (single/ double glazed any special coatings, internal blind or external shading). • Internal equipment heat gains (copiers, lights, PCs, servers etc). • Building construction (suspended ceiling, void depth, and external wall construction). • Location of power supplies and space for external equipment (roof, ground, wall mounted) is the roof strong enough to take the weight of the proposed
Fujitsu.indd 18
equipment? If in doubt, the client or their landlord may have to engage the services of a structural engineer. • Roof access. Can the proposed equipment be manhandled up to and onto the roof without needing a crane? Take measurements of all stairways, lift openings and doorways along the proposed route up to the roof. • Space and possible routes for pipe-work and/or ducting. • Is there any additional mechanical ventilation required to meet building regulations? This is often the case if a new occupied internal space/office is created with no external opening windows. • Check with the customer exactly what he requires in terms of temperature control and whether the system is for cooling only or heating and cooling with independent control for each area. It is also very important to find out if the client has any plans to expand or change the floor plan in any way. If he does, then now is the time to consider building in flexibility to accommodate those future changes. Chances are the client will be more interested in limiting the initial cost, in which case it is also important to point out that a system designed to a price for immediate requirements will cost more to modify or add to in the future. Having undertaken the site survey the next step is to take all the information gathered back to base and crunch some numbers to see what the cooling/heating loads will be. At this stage, you also probably have an idea of what type of system(s) you will be offering, but that is for the next instalment.

TRAINING
October 2015
Steve Dixey from engineering training company, HETA, explains how hiring well trained young engineers can help your business grow and compete
O
n 21st August 2015, The Prime Minister announced plans to increase the number of apprentice places offered by big business and especially SME’s and also look at funding these places. From our perspective as a workbased engineering training provider, SME’s have been the toughest place to recruit apprentices for even with funding available with every young person. A larger number of apprentices for smaller companies are coming on-board, compared to the numbers that
HETA_NEW.indd 22
have traditionally come from our “Blue Chip” clients. These SME’s recognise that if they are to grow or even just compete, they must recruit and retain young people with the ideas to carry the company through into the future markets.
A DOUBLE WHAMMY ON COSTS
The cost of apprenticeships suffers a “double whammy” from the fact that engineering training is expensive to deliver (consumables such as metal, tools), and the wages
a training provider pays to recruit and retain engineering specialists has to reflect market conditions. This is compounded by there being skill shortages so we compete against industry for a shrinking pool of suitable candidates. Engineering trainees don’t get extra funding to reflect this. If the government wants engineers to be trained, there needs to be measures in place to reflect that. This cost may be a disincentive to training providers and employers and this is why a specialist engineering training provider may be the best place to look. Specialist engineering

TRAINING
October 2015
training providers should have an insight into the engineering sector and be able to suggest costeffective methods that may not always look cheap on paper, but, in the long run, provide a well-trained and motivated individual that will be an asset to your company.
SKILLED ENGINEERS, PROPERLY TRAINED
The cost of training can be eye-watering at times but consider this. Cutting corners leads to training on the cheap, done by Powerpoint, by deskilling the training sector and the casualization of training appointments. None of these conditions will help to motivate an experienced engineer to go that extra mile for a learner. You end up ticking boxes and looking at what can be crammed into the available time-frame, something that reduces training to just another commodity. A good engineering training provider cannot have 30 young
HETA_NEW.indd 24
people in a “proper” engineering workshop with potentially hazardous activities going on looked after by one tutor. The health and safety aspects alone renders this a no-go. This type of environment reduces tutors to getting the kids out the other end of the training process without injuring themselves rather than producing well-rounded tradespeople.
READY FOR WORK
In addition to engineering skills, specialist engineering training providers are well-placed to turn out “work-ready” young people. At HETA we train for the workplace as much as for the skills they will need to deploy in their trades. Apprentices clock in and out, they put in a full 40 hour week, 8am until 4 pm, with two 15 minute breaks plus 30 minutes for lunch. As their tutors and lecturers worked in industry, they know what industry wants and ensure that the learners get the skills that
contribute to employability such as time-keeping, good attendance records and a good appreciation of health and safety in the workplace. We will also look to turn out apprentices that have successfully made the transition from “school kid” to a responsible young adult that is an asset to a company. As a potential employer, it is important you get involved and ask questions about the training available, challenge what you feel is not right or suggest improvements that will help get a better worker out the door at the end of the apprenticeship. That will make each training pound go further. A good engineering training provider will be happy to take your feedback on-board. HETA goes even further by having industry stakeholders on the board of directors. Their input not only steers the company but feeds through into meeting HETA have with engineering training standards bodies. www.heta.co.uk

DEFROST
October 2015
Why the future of defrost
is based on phase-change Frigesco’s flash defrost system has won a string of industry awards over the past year, and was recently crowned Refrigeration Product of the Year and Energy Saving Product of the Year in the National ACR Awards 2015.
A
CR Journal looks at the technology behind the innovation, and discovers some unexpected benefits in addition to significant energy savings. trials in working stores by major end users in the UK, the US and South Africa.
CONVENTIONAL COSTS
Frigesco flash defrost system
The main claim to fame for Frigesco’s pioneering flash defrost system is its ability to reduce refrigeration energy use, and therefore cut operating costs for end users. Field trials have shown it can reduce supermarket refrigeration running costs by up to 20 per cent, reason enough to warrant close attention by the retail industry, at a time of intense competition and pressure on profits. The technology uses a carefullycalibrated food-safe phase-change material to capture waste heat from the refrigeration system during normal operation, and use it to carry out high efficiency defrosts of evaporators. The system was developed by a team headed by Professor Tom Davies, and is now undergoing field
Frigesco.indd 26
Energy for defrosting is traditionally obtained from hot gas, via the refrigeration system itself, or directly from the mains in the form of electric defrost. The latter uses small heaters within the cabinet, near the evaporator, to melt frost build-up. There are a number of downsides to these conventional approaches. Hot gas defrost carries a significant energy and performance penalty, as it requires the refrigeration system to operate outside its optimum envelope for significant amounts of time in order to generate the heat for defrosting. This reduces the efficiency of the system and increases running costs. Electric defrost incurs a direct energy penalty, through the consumption of electricity to melt frost using heaters. The use of electric fans adds further to energy consumption.
LEGAL AND SAFETY CHALLENGES In both cases, the addition of significant amounts of heat energy to refrigerated space must be offset by increased refrigeration
input post-defrost, again leading to higher electricity consumption. On the legal and safety front, there has been concern for some time that repeated heating of food in refrigerated spaces may lead to potential hygiene risks. Due to its high specific heat capacity and good insulation properties, accumulated frost requires a lot of energy to melt it. Defrosting a refrigerated display case typically accounts for around 30 per cent of total energy used. When multiplied across a supermarket’s estate, or indeed the combined refrigeration systems in the food supply chain across a whole country, this amounts to an immense drain on energy supplies and a huge additional cost for end users.
A NEW APPROACH Recognising the problem, Frigesco began working on a new approach to defrost that overcomes the downsides of conventional approaches. After several years R&D and field testing, its lowenergy flash defrost system was recently granted full patent protection. Controlled trials have confirmed that it can cut overall energy consumption of refrigeration systems by up to a fifth. Efficiency is improved, as it does not require electrically-driven components to deliver heat energy to frosted evaporators, although small pumps can be used to improve the speed of the process if required. In addition, as it sequesters heat produced by the refrigeration system during normal operation,

maximum electrical draw, giving “head room” in locations where power supplies are near the limit, which may be vital in extreme weather conditions, as experienced in hot summer months; •The more efficient defrost process stops the build-up of frost on floors and walls in www.frigesco.com
NEW BENEFITS The new system uses much lower temperatures, better targeted to effect a complete defrost of the evaporator. This means that the temperature of stored product is maintained within much narrower limits, rather than fluctuating wildly as in the case of a traditional defrost. Although the main benefit is a reduction in energy use and lower running costs, the Frigesco system delivers other attractive benefits. These include: • Improved food hygiene and safety due to more effective defrosts, and more stable temperatures in the refrigerated space; • Longer working life and fewer breakdowns for refrigeration plant, due to more complete defrosts and improved equipment operation; • Potential reductions in equipment capital costs due to design optimisation possible with the use of flash defrost; • Reduction in a retail store’s overall

it adds a sub-cooling effect, improving performance and yielding further energy savings. In thermodynamic terms, the subcooling gain effectively pays for the post-defrost re-chilling required. Traditional defrosting methods are known to be extremely inefficient, with as little as 20 per cent of the energy being used in the defrosting process. Not only is this inefficient, it adds a significant heat gain to the refrigerated space.

CHILLERS
October 2015
Next Generation Chillers and Refrigerants Will Hawkins interviews Trane’s Jeff Moe about their new chillers and the impact of new refrigerants.
T
ell us about the next generation low GWP high efficiency refrigerant solutions for chillers, which is obviously the backbone of the products you have released in the past year.
3. To reduce by 35% the greenhouse gas produced by our own internal facilities and our own automotive fleet by 2020.
We find that sustainability is driven through legislation, especially in Europe; it is also a specific request of our customers. As a result, last year Ingersoll Rand introduced its unique climate commitment, which consists of three different elements:
People often perceive Low GWP refrigerants as less efficient than the refrigerants they are replacing. Is that the case with the refrigerants in your new chillers?
1. To reduce the climate-change impact of our product portfolio by 50% by 2020 via the introduction of new products containing next generation low GWP refrigerants and ones that are raising the bar on energy efficiency. 2. To invest $500m USD in this area by 2020 and to take a lead in the policy environment, as our belief is that the policy environment should incentivise and accelerate the use of these more sustainable technologies.
Trane Sintesis chiller at the factory
Trane.indd 28
That perception is true in some cases, but not true in others. One of the other actions we took as art of our climate commitment was the creation of an EcoWise portfolio. It endorses those products of ours that are delivering both lower environmental impact and higher energy-efficiency. The first two Trane products that came out under the EcoWise portfolio are examples of this. The first product we introduced last year - the ECTV product - is an example of where we were able to move to a near-zero GWP - the latest studies give it a GWP of 1. It is also non-flammable and non-toxic, and maintains the same industry-leading proprietary efficiency levels that we had in our prior products. The second new EcoWise product – the R513a refrigerant - is an HFO/HFC blend, which will deliver 60% reduction in GWP. It also includes some new advanced heat exchanger technology that can give up to 40% reduction in refrigerant charge versus prior traditional designs. Couple those two, and they give nearly a 75% reduction in the direct GWP-related impact by achieving similar efficiencies to 134a. There is a lot of discussion
about CO2. In low temperature refrigeration CO2 is not a bad refrigerant. But, when you are using CO2 in air conditioning applications, working within and past the critical temperature of CO2 the efficiency drops off significantly as the refrigerant temperature goes up. We would see significant loss of efficiency in use of CO2 in that way.
When will you launch the new air-cooled chillers using low-GWP refrigerants? The ECTV centrifugal chiller is shipping now – the first shipment in Europe was at the end of last year. The Sintesis EcoWise product - our air-cooled screw chiller – the first phase of that was the third quarter of last year. The new refrigerant has just recently become available and is ready for shipment now. The second phase - the larger size units - will be ready for shipment in a month or two.
You’ve mentioned working with Honeywell and Dupont - Solstice D refrigerant in the centre of that chiller, it has a very low GWP – is that in the range of products you mentioned of low environmental impact but maintaining energy efficiency? Very much so, yes. The significant elements of the fluid need to be: • low GWP • non-ozone depleting (in Europe) • able to maintain or enhance energy efficiency • able to maintain or enhance safety in use of the product • minimal emissions during the use of the product

CHILLERS
acrjournal.uk
For the first two of these new products the 1233ZD in the centrifugal chiller and the R513a in our screw chiller both of those are non-flammable and non-toxic, so we are able to cover all of the above factors.
How does the capacity of the chiller affect the refrigerant you can use in it? Firstly, specifiers select the refrigerant based on the compressor technology more than on the capacity of the chiller. There is a correlation there too, as the scroll compressors would start at smaller capacities. Then they would go up and there would be some overlap when moving into the screw chillers. After that, it is into largest size capacities. A centrifugal chiller allows for lowpressure fluids; screw and scroll compressors are going to go to the higher pressures. Within compressor technology the capacity of the chiller can be impacted by the pressure, e.g. when we introduced the new ECTV product, the 1233ZD fluid we used was not quite as low pressure as the prior fluid we used outside of Europe (123). Therefore, the little bit higher pressure means that we can deliver slightly larger sized units than before, up to 14 MW.
You’ve also announced recently a range of new small capacity chillers – where do you see them being applied, what can people expect in terms of performance and environmental impact. Those units are approx. from 17 up to 45 KW capacity in size. Today those units are only available with R410a. We are exploring alternative options over the next few years.
Trane.indd 29
Some new next generation fluids will be available earlier than others will - 1233ZD and R513a are available now. When we look at the R410a alternatives, there is no perfect HFO replacement for 410a. We have one that we think may have the best opportunity but we cannot say yet what that is at this stage.
In what type of applications and processes can you use them? The smaller chillers can fit quite well in smaller retail applications, e.g. within the wine industry.
Jeff Moe
different level of concern and increases the challenges of maintaining safety in application in larger charge systems.
Do you see the issue of flammability as a problem with Trane’s new chillers?
I imagine you would need a new whole range of infrastructure.
The answer is: that depends. For the first two new refrigerant launches, flammability is not an issue because they are nonflammable and non-toxic. In the portfolio for the 5-year outlook period – yes, some choices include the use of mildly flammable refrigerants. Is that a concern for us? Absolutely. Is it a concern that we believe we can get past and maintain safety? We certainly believe we can and will do that. Within the flammability categories, you have the new “2L” which is a subset of flammability category 2. In the past, it was just 1, 2 and 3 and today it is 1, 2L, 2 and 3 with 2L being mildly flammable. That is the category we are looking in. Within that category, we see a diversity. On the lower level end we see 1234 ZE or a 1234yf (the latter being what is looking to be the primary replacement for 134a in automotive air conditioning), for both of those we can much more readily see ways to use them safely in application. It is the higher end of the mildly flammable area that raises a
JM: Absolutely. That is why certain refrigerants have come out earlier than others. Our replacement for R123 (which is still very appropriate outside Europe), is 1233ZD. That product can be introduced with minimal changes in the install, as the industry knows how to deal with low-pressure fluids. Similarly, the 134a alternative in our Sintesis EcoWise product is 513a, whose pressures are very similar to 134a. The glide on that blend is almost zero, it acts more like a 410a; if you have some leak in the product, you can fill it up with 513a without the need to worry about the separation of components or glide. When you take mildly flammable fluids with minimal flame propagation, then the lift is not so large. If you are switching to something that is extremely different in pressures for a small servicer this is a capital investment they have to make. It is a change they have to implement. The training element is also significant part of the transition – training the staff so they know how to deal with the new gauges and troubleshoot.

hree companies were contacted by Crown to solve this problem including Thorite, the UK’s biggest distributor of pneumatic products and process systems, with a brief to supply and install advanced, energy-efficient equipment. Thorite carried out site surveys and developed a solution centred on two Parker Adiabatic Air Blast water
coolers to supply cooling water to the hydraulics of the can making equipment. The coolers consist of copper tube and aluminium Magnesium Fin Coil Blocks, direct drive axial fansets, galvanised steel casings, stainless steel collection trays, local fan isolators and variable fan controls as standard. Adiabatic cooling is achieved by mains water distributed over an evaporative cooling media through which incoming air passes. The cooled dry air then passes onto a coil for further cooling. This method prolongs the coil life by reducing coil fouling and negates the need for expensive mains water treatment. Thorite project managed this major capital equipment project from inception to completion. Each of the coolers weighed 3185kg and occupied a floor space 10.5m long by 3.5m wide. This meant there was
insufficient room to site them inside the plant so a large mobile crane was used to lift them on to the roof. Once in place, Thorite provided all ancillary requirements including fabrication, pipework, machinery supports and pipe bridges. Ian Connelly, Crown Packaging’s Technical Manager, had no hesitation in selecting Thorite to supply and install the equipment and said: “Thorite was one of 3 candidates for this project and based on their price and professional presentation was awarded the contract. Our dealings with them have provided a good all-round experience with no major concerns and the equipment is performing precisely as promised. Although it is still early days I am confident that the coolers will help safeguard and boost our output whilst contributing to our on-going drive on energy reduction.”

Keeping Carrots Cool The Norwegian carrot root and vegetable storage business, Lundstad Grønt, needed to update its cooling system which was food safe, non-toxic and biodegradable.
T
hey approached SRS Frigadon to help them to keep their vegetables in good condition for longer at their store in Kolbu. The team at SRS Frigadon, located in Stratford upon Avon, did its homework before embarking on this large 14,000m³ quadruple chamber carrot cold store installation.
THE SOLUTION
They designed and installed a solution which included Frigadon HYCOOL stainless steel chillers, AIA dual discharge coils and HYCOOL heat transfer fluids, which contributed to the huge success of the project. SRS Frigadon provided a fluid refrigeration system that operates at low pressures of only 1.5bar – tap water pressure. This is the perfect solution compared with the high pressure CO2 systems which operate
up to 120bar to the gas cooler. With the demands being to supply such a system to operate at a 98% RH at air temperature of +1°C then the HYCOOL 30 fluid (-4°C flow) was the best selected solution. Another significant factor was to minimise risks of product degradation. The higher HYCOOL operating flow temperature of -4°C enables higher evaporation temperatures and lower pressure drops which, in turn, will reduce compressor energy use. The 300kW hydrocarbon SRS Frigadon stainless steel chiller with only 4 x 5.5kg R1270 Bitzer compressor circuits incorporates the SRS WFD (Warm Fluid Defrost.) enabling a rapid defrosting with the warm HYCOOL circulated through the coils. The idea with the WFD is to allow the HYCOOL temperature to rise, thus melting the ice (if any) from within the coil minimising disturbance
to temperature and humidity balance within the carrot cold stores. Such a defrosting strategy means that the compressors run less to remove all of the unwanted defrost heat which can be generated within other types of refrigeration installations. This minimises defrosting costs.
CONTROLS
The SRS engineering design also included the SRS°Kilowatch energy management control system to ensure energy savings and monitoring. More energy saving come from the EC Low Energy fans fitted to the Frigadon air cooled chiller together with its built-in PEO (Pump Energy Optimisation). This reduces the mass flow of fluid when the cooling demands are low. Heat recovery had also been incorporated within the engineering design of the 300kW Frigadon chiller.

MAINTENANCE
October 2015
clean evaporator and condenser coils In the second “How To…” article by AC&R service and maintenance experts Advanced Engineering, we discuss the problems caused by dirty evaporator and condenser coils, and describe several methods for effective coil cleaning.
A
basic air conditioning system consists of indoor cooling coils or evaporators and outdoor condensing coils (these can be either air or water-cooled). Every part of the operating system must function correctly to accomplish the cooling job efficiently. The coils are the parts of the system where the heat transfer takes place and dirt on a coil will form a barrier to heat transfer – effectively insulating the coil. Heavy dirt build up can also clog the coil and reduce air flow. Dirty, clogged coils can cause many varied problems: • Reduced heat transfer • Decreased cooling capacity • Increased energy consumption • Increased operating pressures and temperatures • Increased wear on the system, which can lead to component damage, system malfunctions and reduced life expectancy • Reduced energy efficiency • Poor indoor air quality and potential for contamination (evaporators only) Before you begin cleaning, it’s important to note that a highimpact pressure washer should not be used to clean air conditioning coils. The water pressures involved can easily damage the coil’s delicate fins; and it is also very
Advanced Engineering.indd 36
easy to push dirt further back into the unit and out of sight, making it much harder to remove. Low pressure systems like our own HydroSprayer coil cleaner applicator are specifically designed for the job and avoid any of the physical damage associated with household pressure washers.
CLEANING THE COILS SuperClean is a heavy duty condenser cleaner with a powerful foaming action. Because it’s heavy duty, it is especially suitable if a unit is particularly dirty or has not been serviced or used for an extended period of time. Before you start any cleaning job, you need to ensure you are wearing the recommended personal protective equipment, which in this case includes safety glasses and a pair of protective gloves. Since SuperClean is a concentrated product, it first needs to be mixed with water. Combine it to the ratio one part SuperClean to three parts water. The easiest way to mix is to measure and add the fluids directly into the HydroSprayer. Usually warm (but not hot) water provides a faster cleaning reaction. Since SuperClean is a foaming

cleaner, it is recommended to start at the bottom of the coils and work across and up with the HydroSprayer. If you start at the top, the foam would naturally run down the coil making it very difficult to tell what has or has not been cleaned. Once SuperClean has been applied in this way you should wait ten minutes for the foaming action to do its work. You’ll start to see the chemical reaction taking place: the foam will develop as it pushes the dirt and debris from the centre of the coil outwards. Then the coils should be thoroughly rinsed with fresh water. This time, though, it is recommended to rinse from the top to the bottom so you’re not washing dirt onto cleaned areas below. It’s important to rinse thoroughly with water so no residual product is left to react when you’re away from the unit.
coils are particularly dirty or have been left unattended for some time they are likely to require a more heavy duty cleaner. Since it is is not a foaming cleaner, RTU CC should be applied across and down, from top to bottom. Apply the cleaner by spraying it directly onto the coils. Once you have sprayed the exposed coils you should again wait ten minutes for the cleaner to be at its most effective. Once the ten minutes is up, the service engineer should thoroughly rinse the unit with fresh water from top to bottom. As with SuperClean, a low pressure HydroSprayer is generally recommended for rinsing, but if an engineer doesn’t have a similar system s/he can always rinse out the RTU CC sprayer bottle with water and use it to spray water onto the coils to rinse the unit thoroughly. As you rinse you will see flecks of dirt rinsing straight off the coils. If you would like specific advice on how to clean your evaporator or condenser coils, contact the experts at Advanced Engineering on their support hotline: +44 (0) 1256 460 300 or visit their YouTube channel for more cleaning tips and guidance.
EasyFoam After Cleaning
GENTLER ALTERNATIVES If an engineer prefers not to use a powerful, heavy duty cleaner, EnviroCoil can be a preferred alternative. EnviroCoil is a universal coil cleaner that is biodegradable, environmentally friendly and suitable for use inside or outdoors. It is gentler than SuperClean and ideal for systems that are regularly maintained.
HASSLE-FREE DIRECT SPRAY COIL CLEANERS EasyFoam is another powerful foaming condenser cleaner, but it comes in a convenient, easyto-use, ready-mixed aerosol. It is perfect for removing stubborn dirt and for use on deep, multi-row condensers. The main benefit of EasyFoam is that it is much faster and more efficient to apply than concentrated cleaners because it doesn’t need to be pre-mixed on site. You also don’t need to use a low

Evaporator coils before and after in one short close-up
pressure HydroSprayer – instead you spray EasyFoam directly onto the coils. As with SuperClean it should be rinsed off after use. RTU CC (Condenser Cleaner) is a handy, ready-to-use biodegradable condenser cleaner in liquid spray form. It comes pre-mixed with its own sprayer, so it’s ready to go straight away. RTU CC is generally recommended for regular routine (preventative) maintenance. If your

Out and About with Will Hawkins
Fläkt Woods
Will Hawkins visits the air movement specialist, Fläkt Woods, at its factory in Colchester to hear how the business is developing.
Inside the Fläkt Woods factory
I
met Ian Morehouse, the UK Managing Director, Operational Marketing Managers, James Griffiths and Andy Cardy who gave me a detailed insight into how they are adapting to a competitive market.
Fläkt Woods has been in Colchester since 1909 producing fans. It now turns over £66 million in the UK, with around 350 employees, and makes about 7,000 fans a month. The Global business specialises in two market sectors, namely ‘air comfort’ and ‘fire safety’. Their solutions go into all types of buildings including offices, factories, shops, schools, power plants and hospitals. One fact about Fläkt Woods is that about 85,000 buildings in the UK contains one of their fire safety or
Out & About.indd 38
ventilation fans. Their products include air handling units, chilled beams, axial fans, chillers and high temperature fans. In the UK, their specialisation is making non-residential and tunnel axial fans, car park safety systems, OEM and industrial fans. Their customers include contractors, consultants and end users (building owners). Original equipment manufacturers (OEM) make up about £17 million of their UK business. These include some of the brand leaders in chillers, power generation and plant. Fläkt Woods is an impressive business, not least because of its transformation in recent years. Since moving to its new factory the business has improved its efficiency and flexibility in a purpose-built unit smaller than its previous site. One measure of its efficiency is the time it takes to walk along the entire production line. It now takes around 75% less time to ‘walk the line’ than at its previous site. That means its air movement products have less distance to travel while being made. In turn, they have more time to make more products.
SO WHAT?
That efficiency means Fläkt Woods is more responsive to its customers.
As a result, orders for custom air movement solutions are an increasing part of their business. Their flexibility means they can often turn solutions around in two weeks. In a competitive market, speed, quality and flexibility are important. It is not just Fläkt Woods’ production capabilities which have brought it success. It’s no good being able to deliver an air movement solution if it’s inefficient. Ian Morehouse was keen to highlight three of their core values which they apply to all their solutions, namely being environmentally friendliness, economy and applied expertise. A recent development is the release of their new ‘JMv’ high efficiency fan. Recent EU legislation (ErP) is driving manufacturers and end users to become more energy efficient. Fläkt Woods is meeting the challenge with new motors (a combination of AC, PM or EC motors), new impellers and variable speed drives (VSD). The measure of success is the combined Fan and Motor Efficiency Grade (FMEG).
DESIGN AND DEVELOPMENT
To make the new design possible, Fläkt Woods’ management team gave the design engineers a ‘blank piece of paper’ to come up with a new solution that would deliver
22/09/2015 14:03

‘high efficiency at a low price’. Using the design team’s strength in computational fluid dynamics (CFD), they arrived at a prototype which they believed could provide them with the efficiency they needed. Using the same motor used with the JMv fan predecessor, the JM, the new fan has 79% total efficiency compared to 70% efficiency with the JM. The FMEG results for the JMv and JM, respectively, are 65 (79% x 82%) and 57 (70% x 82%). The ErP N grade for the JMv is 58. The JM N grade is 50. Impressive results.
WHAT DOES THAT MEAN FOR END USERS?
The JMv fan can reduce energy bills by up to 24%. That builds up to high savings not just in money but in carbon emissions too. The JMv fan range is focused on smaller fans for their portfolio. The JM is still a competitive fan for solutions which need large impellers.
PRODUCTION VALUES Walking around the factory with Steve Riddleston, the Fläkt Woods manufacturing manager, he showed how the engineers make the fans and test their products. It
Out & About.indd 39
is easy to claim that you make high quality products and how your team pays attention to the detail of each unit they make. How do you show it in reality? Firstly, Steve showed us one of his manufacturing team who scans components for imperfections as they enter the factory. It was not a cursory glance at each one. He scans them using a specialised machine which produces an x-ray image of each item. While there, there was a metal component which clearly had a screw embedded into it which should not have been there. Of course, the operator rejected it. Next, at another part of the production line, one of the manufacturing team was removing parts from a sheet of metal which had just been through a metal hole punching machine. Ian Morehouse noticed that the team member was not removing the ‘punched’ items in the best way to save time. Steve noted it and promised to rectify the problem. It is this relentless focus on efficiency and quality which separates Fläkt Woods from just being ‘another manufacturer’. The team has these values in its blood.
WHERE NEXT FOR FLÄKT WOODS?
Ian Morehouse talked about their move into developing more freezer applications for the catering industry in the processing sector as a development. The company is working on industrial machine cooling solutions with clients too. The diversity of markets includes producing fan for wind tunnels, ground-based free fall centres, nuclear power stations and submarines. Recognising that you cannot rely on always hiring people with the right skills, Fläkt Woods has a program to develop internal talent. They back their employees to get further education such as gaining HNC or HND qualifications, as well as Bachelor programs. Visiting Fläkt Woods is a fascinating event. If you ever thought that British manufacturing was a thing of the past, think again. This company shows you that it is alive, well and developing.

DON’T LET YOUR BUILDING get out of By Scott McGavin of Mitsubishi Electric
L
egislation such as Part L and Part F of the Building Regulations and the Energy Performance of Buildings Directive have turned the regulatory guns on energy use within our buildings as never before and the situation is only going to get stricter as the Government looks for ways to meet the country’s carbon reduction targets.
A range of measures have already been introduced, such as the updated F-Gas legislation, which is aimed at eradicating HFCs from air conditioning equipment, and the Energy Savings Opportunities Scheme (ESOS) which will bring efficiency sharply into focus for large organisations. Scott McGavin
Mits DPS.indd 40
For many landlords the situation is also reaching a critical point with the looming deadline of 2018 for buildings which are let to reach a minimum energy rating of E. This means that landlords of F and G rated buildings will be unable to let them out after April 2018 unless they take active steps to improve the efficiency of the building. In addition, the budget set out by the Labour Government in 2008 announced the intention that all new non-domestic buildings should be zero carbon from 2019, and the Conservative/Liberal Democrat coalition government reaffirmed this stance in December 2010. The current thinking is that the overall approach to achieving zero carbon non-domestic buildings should be led by a ‘fabric first’ hierarchy of measures to reduce the demand for heating, cooling, mechanical ventilation and electric lighting in the non-domestic sector. But hot on the heels of this is the requirement to ensure that the remaining demand for services is met with high efficiency equipment. While these objectives may seem harsh, they make sense when you address the lifetime costs of a building because the vast majority of the costs which are associated with the running of a commercial building are swallowed up by the building services.
Therefore, in line with the quest for zero carbon and in order to meet the government’s overall carbon reduction target of 80 per cent compared to 1990 levels by 2050, finding ways to make building services operate more efficiently has become a key focus.
CONTROL THE LIFETIME COSTS There is no easy way to achieve true efficiency because the very nature of a commercial building means that there are numerous factors to take into account. But when you start to address the issue there is one simple word which is constantly cropping up and that is control. The British Standard BS EN 15232 deals with the impact of building controls and building energy management systems (BEMS) on energy efficiency and provides a structured list of controls and building-automation technologies which have an impact on the energy performance of buildings. The standard deals with a range of controls products such as automatic detection devices, demand-based controls such as CO2 sensors, and controlsbased strategies such as night cooling. It also gives a method to define minimum requirements for controls for buildings of different

AIR CONDITIONING
41 acrjournal.uk
complexities. Most usefully, the standard provides detailed methods to assess the impact of building controls on the energy performance of a given building. The standard can therefore be used to demonstrate the energy savings of different types of building control, to compare against the costs. But while this may sound like a very easy win, the introduction of building controls brings with it a whole new problem. One of the main issues with building controls in the commercial environment is that they are frequently used as a glorified on/ off switch and as such they are not being used to their full potential. An additional issue is that every piece of plant comes with its own control system which invariably works in isolation. It is clear that this needs to change. In order to get the best performance from a building there is a basic need for all of the building services to communicate through an effective control solution - a smarter solution that transcends brand boundaries and puts performance at the top of its list of objectives through an integrated approach.
AN INTEGRATED APPROACH Aside from better performance, there are other benefits to bringing different systems together so that they can communicate with each other on a single platform. Installation costs, for one, may be reduced thanks to integrated systems sharing the same physical network for communication. Consultants are also afforded greater choice at the design stage; with the range of devices they can choose from unshackled from the constraints of considering only one manufacturer.
Mits DPS.indd 41
Furthermore, if all building services can be operated from the same central interface, this makes for simpler and more time-efficient building operation. This was one of the driving forces behind the introduction of MelcoBEMS which provides an interface between Mitsubishi Electric air conditioning equipment and Building Energy Management Systems (BEMS) via the Modbus or BACnet protocol. This type of solution is increasingly being demanded in the commercial market by building owners and managers who recognise that the only way to achieve true energy savings and meet the legislative requirements is through the use of a flexible and intelligent solution which effectively joins the dots as far as building-wide control is concerned. The enhanced capabilities that
modern building services plant offers is something which the industry now takes for granted because the rapid evolution of technology means that we now expect a high level of efficiency from this type of equipment. But even the most efficient piece of kit has its limitations if it is not controlled effectively because the ability to anticipate, control, monitor and report performance remains a key factor in achieving reductions in energy use and running costs. It is clear therefore that the only way to get the best performance out of a building is to ensure that the building services are able to communicate and work together. This will become more important as building owners and managers seek to reduce their energy use to meet the increasingly tough environmental requirements being placed on commercial buildings.

REFRIGERANTS
October 2015
F-GAS COMPLIANCE – it really is that simple A-Gas Managing Director John Ormerod on a new tool which will help engineers and end-users meet the demands of F-Gas compliance
T
o borrow a slogan from a famous television insurance advert, change happens. Few working in the refrigeration and air conditioning industry would doubt that the pace of change in the way we use refrigerants is increasing and to a large extent it is how we deal with this that is important.
The latest raft of F-Gas Regulations which came into affect in January this year position low GWP (Global Warming Potential) refrigerants at the heart of change in the industry. The phase out of high GWP refrigerants will alter the face of the industry and set new challenges for all who work with refrigerants. How to manage this is a key element which will ultimately determine the success of the new regulations. The increased use of new and unfamiliar refrigerants will affect those working in all parts of the industry but undoubtedly the workforce that will feel the effects the most will be the engineers and contractors. The legislation that came into force at the beginning of the year set the industry the task of reporting leaks based on CO2 equivalent calculations rather than kilograms. It also demanded follow-up checks
A-Gas.indd 42
from as early as 30 days to ensure that the work had been successful.
and able to meet the changing needs of the refrigeration industry.
LEGAL LOG BOOKS
INDUSTRY INPUT
The regulations also require accurate F-Gas log books. Traditional methods of refrigerant reporting are time consuming and require a large paper trail. With this there is the added burden of endless filing and the risk of losing paper copies. So I am sure you will agree that any method that cuts down on the use of paper and provides accurate reports is welcome, especially if this lessens the impact on the environment. But with the industry largely relying on manual logs, any alternative has to fully fit the needs of the user without making the job more complicated. The only way of achieving this is to ask those working in the industry what they need to help them. This is what A-Gas did. We undertook extensive research at many levels of the industry to find out exactly what was needed to replace the old style paper-based system and provide something that was more efficient
We spoke to industry experts, distributors, engineers and end users. We quickly discovered that they wanted an easy to use tool that would calculate refrigerant usage in CO2 terms and identify leak checking requirements. They wanted a device that would track cylinder use and store customer, site and asset information ready to create jobs and record the use of refrigerants. They wanted a tool with a built-in barcode scanner that would gather accurate information in an instant. They wanted the ability to analyse performance when they needed it to meet the needs of F-Gas compliance and ensure end user customer satisfaction. The devil is in the detail with leak detection and to have a handy piece of kit which can make this simple to understand was the clear message we were receiving. Engineers wanted access to information at their fingertips. They wanted reports on what work had

been carried out on a make or model of equipment to the type and the quantity of the refrigerant used at a specific site.
TRACKING AND TRACING They wanted access to contractor reports. For example, information on every cylinder used by those involved in the work – key data that traditionally required someone to search through a mountain of paper. We came to understand that with the new regulations the ability to analyse engineer performance is also a vital component in efficient refrigerant management. The industry is beginning to recognise that the ability to track refrigerant usage by the cylinder, equipment and the customer is becoming a necessity – and if you can achieve this online, so much the better. That’s why A-Gas has launched Gas-Trak Online™ (GTO), an F-Gas reporting and cylindertracking tool, designed to make leak detecting and refrigerant management easier. Free to download on smartphones and tablets, this app comes complete with the key features needed to help users comply with the complex issues presented by the F-Gas Regulations. We quickly understood that if

Here at A-Gas we recognise the difficulty faced in trying to manage cylinder use and report leakage as the new regulations begin to take effect over the coming years. We are working in a changing industry and no amount of training and tutorial will compensate for not having a tool which will do the job easily and efficiently. Be sure that the latest F-Gas Regulations are only the beginning of a series of major changes to affect our industry. A more holistic approach in how we use and work with refrigerants is emerging around the world. Information at the touch of a button for those working at the sharp end will become increasingly valuable to determine the way we manage this. www.agas.com

Details about membership of industry asscociations and the benefits from being part of them for you (if applicable) Since 2007 I have been a member of the Deutsche Kälteund Klimatechnischer Verein e.V. (German association for refrigeration and air conditioning). This non-profit organisation provides a technical and scientific forum for the sector, promotes work in the area of refrigeration, air conditioning and heating equipment and supports the exchange of experience between members and helps them to keep in touch.
Carolin Dittmer, Market Sector Expert Supermarket. Bitzer Education: Where did you study and what course/diploma/ degree did they gain? I studied at ESaK (the European academy of refrigeration and air conditioning at the vocational academy in Maintal (Germany) and successfully graduated as a certified engineer in refrigeration system technology. My field of study was mechanical engineering and focused on refrigeration system technology and I wrote my thesis, ‘Experimental Analysis of Microchannel Cold Plates for Electronics Cooling’ in the USA at Purdue University in West Lafayette, Indiana.
Details of current employer (or own business), including location I work at BITZER headquarters in Sindelfingen, Germany. The BITZER Group is the world’s largest independent manufacturer of refrigeration compressors. This long-standing company was founded in 1934 and today is represented at 42 locations around the world. BITZER produces and distributes reciprocating, screw and scroll compressors as well as pressure vessels. Approximately 3,400 employees work at BITZER and in 2014 its turnover was about 657 million euros.
What attracted you to the industry? Enthusiasm for refrigeration systems runs in my family. My father
is a mechanic for refrigeration plant, so I had an early insight into an exciting area of work. As I studied the subject, I found that the field of refrigeration is much more extensive than just commercial refrigeration systems for the butcher or baker around the corner. My interest in the various applications ultimately led to me spending some time after my graduation in a job as a project engineer for the national area in a medium-sized company making refrigeration systems with about 40 staff. After some time, I increasingly wanted to extend my horizons and also work on international projects. At this time, BITZER offered me a unique opportunity. Their entry programme for young engineers made it possible for me to get to know a variety of departments over 18 months. I was thus able to work on various projects in design, development, application engineering and in sales, and was responsible for my own smaller projects. I was then able to complete the programme by spending three months at a production facility in Atlanta, Georgia. That was a valuable experience. It not only helped me to expand my technical and language skills, but it also convinced me that I should work for a manufacturer of refrigeration components. In general terms I find the international nature of the sector attractive. As the products are used around the world, for Continued on page 46

each project, we have to reconcile very different climatic conditions, legal requirements and specific customer wishes.
What do you specialise in now? Or, what type of projects do your work on? As a Market Sector Expert for Supermarkets, I am part of a team of the same name and have specialised in all of the associated subjects. The declared aim is to identify the requirements and needs of the mostly globally active target group and to build on that by working hand in hand with product management to initiate the development of products. An important aspect of my role consists in transferring knowledge within the organisation and in supporting the worldwide BITZER subsidiaries. In addition to that, I also train customers, for example at BITZER International Refrigeration Seminars, abbreviated as IRS.
What do you know about the industry which you wished you had known before? If I had known earlier on that I would be working in such an international field, I would have improved my language skills earlier on and would have learned another language such as Spanish.
44_Women in ACR_NEW.indd 46
Where do you see your What excites/interests you about the industry and your part in it now? career developing? I am enthusiastic about the professionalism with which refrigeration compressors are developed today. The scope of the simulations and tests is really impressive. For the best possible efficiency and operating reliability, intelligent electronics are increasingly being used in the products. I am particularly pleased when even customers who were initially sceptical respond positively to our new developments. For some years, the holistic approach has been gaining in importance. For supermarkets for instance, it is not just a question of supplying suitably dimensioned compressors for a combined system which supplies the medium temperature and low temperature systems. Instead, subjects such as air conditioning, heating and the heating of waste water are included in the design of the system and I find it very interesting to discuss all of that with planners and decision makers.
What would you say to other women who are considering coming into the ACR industry? Anyone who is interested in the technology and applications should really make use of the opportunity! There are numerous career options and fields of work, not just in design or development, but also in departments such as application engineering, sales, marketing and business development.
In a constantly growing company like BITZER and a sector as multifaceted as refrigeration and air conditioning there are always new options to further your personal development. Early in April I started the job in my new area of responsibility. Now I am first concentrating on making a success of this.
What are the challenges of this industry? It is a challenge to constantly keep developing the products for energy efficiency, sustainability, operating reliability and quality as well as optimising the operating costs. The refrigerant is also an important subject, which, depending on the country or region, is subject to varying legal restrictions. The requirements of the EU such as the F-gas Regulation or the US Environmental Protection Agency play a large role.
What are the benefits of being in your role (e.g. travelling, variety, monetary?) At BITZER, I like the diverse range of jobs and my work is full of variety. That means that I don’t just work in the office, but also regularly visit customers and work together with colleagues and customers from other countries and cultures. For me, that is the ideal combination of technical and strategic responsibility.

Toshiba innovation and training key to growth plans Toshiba Air Conditioning (a division of Toshiba Carrier UK Limited) recently revealed ambitious plans to double sales by 2020, as part of a five year growth strategy.
I
t is supporting the initiative with the launch of innovative new air conditioning products, such as its latest SMMS-e VRF system, increased UK stocking levels, a major expansion in worldwide production capacity, plus its roll-out of a UK network of training centres and a new global training facility.
Stock levels at the company’s Plymouth site are being increased dramatically with the addition of a further 44,000 sq ft of racking space, ensuring immediate availability across all popular ranges of Toshiba split and VRF air conditioning.
INVESTING Investment in research and development is also being significantly increased, both in the
Company Profile.indd 48
UK and globally, with Toshiba’s main factories taking on an additional 350 design engineers. This will enable the company to fast-track the development and introduction of innovative air conditioning technologies in the future. A major extension to Toshiba’s advanced Thailand factory is under way, including expansion of its world-class research and development facilities, due for completion later this year. This includes creation of a new global Technical Training Centre, with capacity to train 150 delegates at a time, equipped with Toshiba’s full range of air conditioning and control technology. This joins Toshiba’s award-winning network of training facilities, covering the UK and Ireland, and puts the company in the forefront of air conditioning training providers. On a corporate level, the planned growth is supported by the Building and Industrial
System (BIS) group within parent United Technologies Corporation, bringing together amongst others Toshiba Air Conditioning, Carrier Air Conditioning, Chubb Fire and Security and Otis, the lift specialists.
LATEST VRF The latest generation of Toshiba’s market-leading VRF air conditioning, the SMMS-e, was launched at Twickenham last month, alongside the opening game of the Rugby World Cup 2015. It sets a new industry benchmark for energy efficiency, heating performance and a revolutionary “no-contact” wireless commissioning system. Developments in three core technologies – the compressor, heat exchanger and advanced intelligent control – combine to ensure all outdoor units in Toshiba’s new SMMS-e VRF range have an ESEER (European Seasonally Adjusted Energy Efficiency Rating) higher than 7, an industry first. At its heart is a new dual vane twin rotary compressor, developed and manufactured by Toshiba, which uses a two-stage compression process for improved efficiency and performance. Wear surfaces on compression vanes are treated with a high-tech DiamondLike Carbon (DLC) coating, giving outstanding hardness, wear resistance and reliability. It enables a significant increase in compressor rotation speed,

resulting in a higher displacement volume – up to 50 per cent greater than for the previous generation of VRF systems. The enables a higher capacity to be obtained from a smaller compressor, with less power consumption. The system’s heat exchanger has been completely redesigned, using smaller diameter tube arranged in three rows in the coil, compared with two rows in the previous model, resulting in a 13 per cent increase in surface area available for heat transfer, further improving performance and efficiency. The capacity of the new generation heat exchanger, previously fixed, can be adjusted to match the current load and ambient conditions. The three-way variable heat exchanger enables the VRF’s control system to automatically select the optimum setting. In maximum, 100 per cent of heat exchange capacity is used to deliver full cooling in high outdoor ambient. In the mid-range option, 80 per cent of heat transfer capacity is employed in average outdoor temperatures. And in the lowest setting, just 20 per cent of heat exchanger capacity is used to provide gentle operation when outdoor temperatures are low. The SMMS-e is notable in being able to provide continuous heating, with no requirement to stop during defrosts, or having to use energy to charge other components as with alternative systems. This
8.0 7.5
is made possible by the use of a new hot-gas bypass control, which simultaneously defrosts outdoor heat exchanger coils, while allowing the indoor unit to continue operating in heating mode. David Dunn, Director and General Manager of Toshiba Air Conditioning, said: “SMMS-e is Toshiba’s latest and greatest VRF system to date. It embodies some important technical developments, not least on the compressor and controls front, which extend efficiency and the application envelope for VRF even further into new territory. “While end users benefit from reductions in running costs and enhanced comfort conditions,
installers can take advantage of the new wireless commissioning and diagnostics system, which reduces installation time and opens up new possibilities for fast data exchange – without laying a finger on a unit. We believe the SMMS-e takes VRF technology a great leap forward, and is set to be a winner.” A key element in the growth plan is to continue to build on and strengthen Toshiba’s distribution network, in both the UK and Ireland. This includes continuing to support and invest in existing distributors, while fostering the development of new initiatives to make Toshiba products available to new and existing customers.

How Montrose Port Authority Saves £37,000
a Year in Energy Costs Montrose Port Authority had a problem with their ancient oil boiler heating system which heated the organisation’s office block.
E
ach year, the Scottish port authority spent £41,000 on oil and £51,000 a year on electricity to heat and power the building which is subdivided into offices for local oil industry businesses. The port authority’s office block was built in the 1950s and 1960s, which is split into individual offices and let out to a number of businesses in the shipping industry. They were happy with the building until, when reviewing costs, they realised how much it was costing them in energy bills. The costs came to the attention after one of their tenants, an oil industry training business, wanted to refurbish its offices and needed a new cooling solution. Fortunately, local contractor Specialist Mechanical Services (SMS), run and part-owned by Graeme Fox, had a solution to the high bills and inefficient heating system.

each in six toilet washrooms as well as six small kitchens throughout the building. The building was about to have a major overhaul office by office and the client wanted all work to be coordinated during the refurbishment works which were scheduled to start in April 2013 with a completion date of January 2014. SMS opted for Toshiba heat pump air conditioning units throughout the building with a Panasonic heat pump supplying the domestic hot water and some corridor public space heating. Graeme Fox’s business wanted extremely reliable equipment which provided high air off temperatures and consistently low power usage. In addition, it was important to provide straightforward, easy to use controls for the client. Graeme decided against using VRF technology because, it was going to be difficult to install in the required stages without major upheaval and inconvenience to all tenants and the cost would have made the project less viable.
FOUR YEAR PAY BACK SMS worked on estimated running costs compared with the existing fuel and service costs. They projected annual savings of around £20,000 against a project cost of around £80,000. That would mean a four year payback. Each tenant has an individual distribution board with meter so that accurate billing is possible for energy use. It also encourages responsible energy use for each tenant. The savings (see table below) from the new system are clearly visible. Since the commissioning the system, there is no oil in use for space heating or hot water. An additional benefit from the heat pump air conditioning is the cooling capability in the summer. Tenants no longer have to open the windows in the hot months to let heat out of their offices.
Graeme Fox.indd 51
HEAT PUMP COOLING The training business approached Specialist Mechanical Services to help them keep their offices at a regular, comfortable temperature. The building’s heating system was a problem in that they could not turn it off, which made the offices unbearably hot in the summer. The oil-fired boiler provided heating through low level perimeter radiator panel heating. The system is so old that many of the baffles were broken preventing it from being controlled. The company could open the windows to let the heat out, but when ships were unloaded on the quay opposite, it became too noisy in the rooms. Graeme Fox installed a heat pump comfort cooling system for the offices to give them efficient cooling in the summer and heating in the winter.
A BIGGER SOLUTION When the Port Authority saw what SMS had done for their tenant they asked if they could look at the entire building and come up with a plan for improving their carbon footprint and reduce their annual running costs. The priority was heating because, although the first tenant wanted cooling in the summer, nobody else was asking for cooling. Domestic hot water was supplied from an old calorifier fed from the same oil boilers. It feeds four hot water taps
FURTHER REFURBISHMENT PLANS The client was clearly delighted with the results showing even greater savings than Graeme Fox had estimated. Montrose Port Authority brought forward a number of other modernisation and refurbishment plans that were originally planned for next year. The actual annual savings (~£37,000) are nearly double the estimated annual savings projected at £20,000 freeing up considerable cash for other works. The tenants themselves are delighted as they now have individual control to reflect their own needs rather than the previous situation whereby they had heat emitting from the perimeter radiators panels even if they didn’t want it.

The NIBE F470 technical diagram
Getting to grips with
exhaust air heat pumps An exhaust air heat pump is a renewable technology that works by harnessing waste heat to meet a property’s heating and hot water demands – while simultaneously providing it with a supply of clean, fresh air for ventilation purposes. Phil Hurley, managing director at NIBE, explains exactly how they work.

he exhaust air heat pump (EAHP) process relies on a system of external wall vents, which draw in fresh air from outside and circulate it around the building. This mechanical ventilation system forms an essential part of the technology – providing a comfortable, healthy living environment for residents, and helping to protect against issues like damp and mould. Given EAHPs are designed for use in smaller buildings with high levels of insulation and minimal heat loss, this circulating air is naturally warmed as it passes through
each room. Internal ceiling exhaust valves (positioned in the property’s ‘wet rooms’, such as the kitchen and bathrooms) then draw this warmed air through a series of ducts and back to the heat pump itself. Inside the unit, the warm, stale air is passed through an evaporator, which extracts the energy present (an average of 20oC) and uses it to heat the refrigerant gas. This heated gas is then passed downwards through a condenser coil found in the unit’s built-in hot water cylinder. As a result, water stored inside is heated through the cylinder’s inner jacket, and can be
utilised to provide space heating and hot water. The used cold air is then expelled outside to an external wall vent (which must be sited carefully as air leaving the system could be as cold as -10oC). As well as making the most of energy present inside a building to meet the property’s everyday heating and hot water needs, EAHP systems also provide necessary ventilation without the need to open windows and waste heat. This is a particular must for properties with high levels of insulation and airtightness, such as new builds. Getting the most out of an EAHP As is the case with any renewable heating technology, EAHPs must always be specified and installed by an expert to ensure that they perform to their full potential, and deliver optimum results for end-users. Developing a robust understanding of the applications

best suited to the technology, as well as how to design, fit, operate and maintain it correctly, is crucial – and as an installer, undertaking the right product training is a key part of this. Part of developing an understanding of the intricacies of designing, fitting and maintaining an EAHP system is correct specification; ensuring that the property itself is fit for purpose. The best way to do this is by taking an ‘insulate before you generate’ approach. The following checklist outlines what installers need to cover for a successful, start-tofinish EAHP specification: Ensuring airtightness Ensuring a property is sufficiently airtight to accommodate an EAHP (as with any mechanical ventilation system) is paramount. Not only does airtightness help to keep heat in, but it can also prevent stale air and moisture from escaping – and a supply of fresh, clean, dry air is essential to keep a building and its inhabitants healthy. It helps guard against the build-up of bacteria and moisture that can cause damp, mould and airborne allergens. Part L1A of Building Regulations on airtightness stipulates that the rate of air escaping between the cracks in a building’s fabric should never exceed 10m³/h/m²@50pa. In other words, no more than 10m³ of air should escape per hour for every m² of the envelope surface area, at an internal air pressure of 50 pascals. To put this into context, BRE research shows that houses with air escaping at 5m³/ hour use 40 percent less energy for space heating than ones that leak at 10m³/hour – and to meet PassivHaus standards, air leakage cannot exceed 1m³/hour. To reap the best possible results from EAHP technology, NIBE recommends that air leakage should not exceed 5m³/hour. If it does, the heat pump reacts by drawing in more cold air from outside than it needs – and this, in

F470) are built for larger flats and small houses with heat loads up to 4kW.
CALCULATING HEAT LOSS
LOCATION, LOCATION, LOCATION
Establishing a property’s heat loss is the next vital step. This means carrying out a full heatloss calculation using a method that complies with BS EN 12831 (based on internal and external temperatures), the results of which will indicate the required output for the EAHP itself. Choosing the right product The specific EAHP product choice can only happen after the property’s heat loss and airtightness levels have been determined. At this point, being aware of the unique capabilities of different EAHP models is a must. Factors like property size and heating requirements are always high on the list when specifying the right system for any project, and EAHPs are no exception. For example, for smaller flats with heat loads up to 3kW, more compact models like the NIBE F205 are ideal, while larger models (e.g. F370 and
When deciding on the location of an EAHP unit, always consider its size and weight. This impact on access and lifting equipment may be required. As with a conventional boiler, EAHP units need to be sited somewhere that will allow for the necessary ducting – so next to an outside wall is ideal.

Our bespoke intermediate course is aimed at experienced MCS-accredited heating engineers, enabling them to upskill to the level needed to carry out successful EAHP installations. Across the
whole heat pump industry, there is an overarching need to maintain the highest possible standards at all times – which is why we’ve made fitting by an MCS-accredited installer a condition of our manufacturer warranty.

PUTTING THE CUSTOMER FIRST Once the EAHP is fully up and running, it is also the installer’s responsibility to show the customer how to operate their new heating system correctly. Unlike the traditional on/off boilers that many consumers are familiar with, the most economical and effective way to use an EAHP is to keep it in operation at all times. The systems are designed to run continuously (similar to underfloor heating), thus providing a constant, comfortable temperature in the property, with residents needing to do very little to regulate and control the heating in their home. Installers have a vital role to play in consumer education at this stage of the process – providing invaluable support that will ensure customers get the best possible experience from their system.

HEATING AND COOLING
October 2015
When 2-pipe does
go into 3-pipe When it comes to air conditioning upgrades, refurbishment or retrofit, one of the major headaches faced by system designers is the challenge posed by having to replace a 2-pipe system with a 3-pipe system.
T
he physical disruption to the existing building fabric, coupled with the need for new hardware and ancillary equipment – not to mention time, crane-lift and labour costs – can be prohibitive.
However, system designers face this scenario as more relatively newly built; speculative commercial buildings come into first-time use. Unfortunately, today open plan office designs are making way for individual office layouts. Where you previously had, say, five floors of open-plan office space with the appropriate 2-pipe air conditioning services, building owners redesign the interiors to incorporate multiple smaller offices on each floor. Hence, the requirement for individually controlled, simultaneous heating and cooling solutions.
EXISTING 2-PIPE VRF The Mill, Barrow Street, Dublin
This was precisely the scenario faced by the system designers
when they had to reconfigure the services for the ‘The Mill’ office complex in Barrow St, Dublin for a high profile, international client. Designer Group did the mechanical and electrical installation on the project. Designer Group appointed Tech because it had completed the original installation in conjunction with Hitachi Ireland. The existing system comprised a 2-pipe Hitachi VRF set-free system with five ducted units operating off one outside unit on each floor. While the new interior office configuration called for a 3-pipe solution, conversion was no problem because Hitachi is, apparently, the only manufacturer whose outdoor units can support both 2-pipe and 3-pipe systems. Hence, there was no need for new outdoor units, just the simple addition of Hitachi changeover branch boxes.
ENOUGH CAPACITY FOR MORE Moreover, the capacity of the existing outdoor units was also sufficient to serve the additional indoor units required for the extra offices, while the modular design added multi-flex capability. “Another requirement was for
LEED accreditation and this too was achievable with the Hitachi installation”, says Paul Byrne, Technical Sales Manager, Tech Refrigeration & Air Conditioning. “Using Hitachi’s CS Net Web controller and the Hitachi HiToolKit software programme, we were able to devise the most efficient and cost-effective solution.” By using CS Net Web – and because Hitachi is the only manufacturer that has a dedicated off-coil thermistor on all of its indoor units – draft prevention is guaranteed. Other benefits of CS Net Web include: • Centralised independent control of up to 640 indoor units (four connected devices); • Remote control via Web/Lan network; • Timer: unlimited calendar configuration; • Outdoor control; • Heating fan stop during thermo off (heat draft); • Integrated email alert; • Calculation of energy consumption; • Multiple access by password; • Total control over system functionalities. “Given the many new challenges retrofit poses, especially in relation to previously unoccupied but newly-built and fully fitted out commercial premises” says Fergus Daly, Area Sales Manager, Hitachi, “clients, consultants and installers can trust in Hitachi to deliver an energy efficient, cost effective solution.” Contact Fergus Daly, Hitachi Ireland.

New portable multi-gas detector provides enhanced accuracy, reliability and ease of use Crowcon has a new portable multigas detector which integrates innovative features, providing advanced protection for employees working in harsh environments and minimising the cost of ownership through faster servicing. The T4 detector will enable companies to ensure compliance to safety standards by protecting employees against unsafe levels of the most commonly monitored gas combination carbon monoxide (CO), oxygen (O2), hydrogen sulphide (H2S), and a range of flammable gases. The clip-on filter plates make it faster and easier for users to replace the gas filter, which prevents the detector’s sensors from being compromised by dirt, dust or contamination in the working environment. The T4’s ease of use also includes one-button operation which reduces the amount of training required and is very easy to operate while wearing gloves. www.crowcon.com

Frascold Announces Howard Davis to Retire Italian compressor manufacturer announced that Howard Davis, their sales manager for the UK and Republic of Ireland, is to retire at the end of September. Howard Davis has been with Frascold for six years, raising their profile and building sales in his territory. Howard grew the reputation, presence and new business for Frascold, partly through his long and deep industry experience, but also through his passion and good humour. His great sense of humour and warm personality made Howard very approachable and popular among his customers. This was always backed up with a huge depth of knowledge, energy and enthusiasm for his work. He is a great team player and on recent road shows other exhibitors noted his sense of camaraderie and good-natured teasing. Howard liked to give everyone a nickname based upon a particular trait or story. Once you had a nickname, you knew you were ‘part of the gang’. Howard Davis started out in the heat pump and refrigeration business 53 years ago, working with some of the top companies, products and solutions in the industry. But, as Howard said: “The time has come for new blood to pick up the rein.” Frascold stated that they would like to thank their customers for the support given to Howard in the last six years, and to the company. In the meantime, Vincenzo Isgrò will be managing the UK and Ireland territory and Milena Vergottini will still provide back office support for customers until Frascold appoints a new sales manager. The ACR Journal team wishes Howard Davis a happy retirement. Steve Taliadores, from LU-VE UK, provided the ACR Journal with some amusing anecdotes about Howard, which you can read online here ( ). One concerns a story about someone’s job in the pig industry, and another about Indian food. If anyone has any interesting or humourous anecdotes they wish to share with the Journal, please email the editor, Will Hawkins willh@warnersgroup.co.uk
