Leak detection – does it matter?

10

Of course, that’s a stupid question.

Leak detection is important and it matters. Most systems will leak at some point in their lifetime. Some systems leak all the time.

Detecting where the leak is in the system can be a challenge. There are plenty of signs to show that a system is leaking (e.g. pressure drops, decreasing efficiency or, perhaps, the smell). To find the leak there are simple methods (e.g. soapy water), handy methods (e.g. handheld detectors), chemical systems and highly sophisticated methods (e.g. infrared). All are valid and have their pros and cons.

In addition, the EN378 legislation (Refrigerant Leak Prevention and Minimisation) is still evolving but it is close to completion. Unsurprisingly, EN378 has become a top topic on the ACR Journal website (see article here: http://w2u.eu/EN378Update).

And, the debates continue on which is the best solution or approach to preventing and curing refrigerant leaks.

Which refrigerant leak detection and prevention methods do you use?

DISTRICT HEATING: TOSHIBA LAUNCHES 7-YEAR WARRANTY SCHEME ASSOCIATIONS COLLABORATE

FOR TECHNICAL EVENING Dr Andy Pearson (right)

The ASHRAE UK Midlands Section in association with the IOR, CIBSE West Midlands, BSRA, and the BEI (Birmingham Energy Institute) will be holding an evening technical meeting titled “Low carbon district heating” by Dr Andy Pearson who recently become a Fellow member of ASHRAE. There has been a rapid and remarkable increase in discussion of industrial-sized heat pump systems for district heating in the UK over the last three years. Heat networks are not a new idea but they have traditionally been seen as a very “unBritish” way of delivering domestic heating.

There have been significant technical challenges to overcome. Using one installation as a case study example, Dr Andy Pearson, ASHRAE Fellow and Group Managing Director of Star Refrigeration Ltd, will describe the concept, the difficulties faced and the ways in which they were overcome.

ASHRAE UK Midlands Section President Steve Gill said that “We are delighted to have Andy present on such an important subject. There are has already been a lot of interest from people wishing to attend so will be also be the Section’s first webinar”.

Steve, who is also President of the IOR said that it is wonderful how the five local societies have worked together to open this event to members from them all.

“We advance by sharing knowledge to this industry and by working closer with our fellow associated professionals.”

Toshiba Air Conditioning has a new seven-year warranty scheme to the market which targets the skills and competence of installers.

Toshiba’s UK director and general manager, David Dunn said: “The industry’s approach to warranty cover has traditionally been based on how much a customer spends with the manufacturer. This is unhelpful and illogical, as in practical terms what matters for warranty purposes is the technical proficiency of the installer, and how competent they are in carrying out installation, commissioning and on-going servicing of the equipment.”

“The new Toshiba scheme recognises this, and gives proper weight to the level of technical training and competence of installers, translating this into a commensurate level of warranty cover.”

The new, enhanced warranty is an addition to Toshiba’s existing, standard seven-year scheme. Installers will need to be F-Gas registered and have completed three ‘relevant’ Toshiba training courses. In addition, installers

have to file project commissioning and maintenance reports online.

The standard seven-year warranty scheme only requires installers to complete three relevant Toshiba courses and be F-Gas registered. Installers with F-Gas registration but who have not completed Toshiba training are limited to five-year warranties.

David Dunn added: “Linking warranties to competence is a completely sensible approach. Our aim is to incentivise installers to raise their game by taking advantage of Toshiba’s training programme to improve their knowledge and skills.”

Longer manufacturer warranties have a reputation for driving greater loyalty and higher sales from contractors and installers in the air conditioning and refrigeration industry. Toshiba’s move should prove to be an attractive benefit of installing Toshiba’s solutions.

Targeting better skills amongst its partners is a wise move by Toshiba to help increase its sales.

The event is free. See details below: Date: 14th June 2016 Time: 6PM Location: Birmingham University, room McE-G26 in the Civil and Mechanical Engineering Building y3 Map link: http://www.birmingham. ac.uk/Documents/university/ edgbaston-campus-map.pdf

Honeywell announced last week that it has signed an agreement with Chinese refrigerant manufacturer, Juhua Group, to make their auto air conditioning refrigerant, Solstice yf.

FGJuhua Group will make Solstice yf (R1234yf) in China for Honeywell to supply the local, USA and European markets. Juhua will start making the refrigerant in late 2016. Honeywell already makes R1234yf in the USA for the local market. The new, Chinese manufacturer will boost supply into the USA to meet growing demand.

Solstice yf is a ‘near replacement’ for R1234a and has a global warming potential (GWP) of less than 1.

R134ahas a GWP of 1,300.

Ken Gayer, Honeywell vice president and general manager of the company’s fluorine product division said: “This agreement with Juhua will ensure supply to meet growing global demand as well as to help support future adoption of low-global-warmingpotential products in China in response to concerns about increasing global greenhouse gas emissions.”

Honeywell has invested around $300 million into the production of Solstice yf to keep up with the growing demand.

The refrigerant is commonly used in mobile air conditioning systems.

New Apprenticeship Scheme L

FOR THE ACR AND HEAT PUMP IN The refrigeration, air conditioning and heat pump (RACHP) industry took a major step forward this week in the challenge to encourage more young people into the sector with the launch of its new Engineering Technician Apprenticeship scheme.

T

he new apprenticeship, co-launched by ACRIB, the Institute of Refrigeration and employers as part of the national apprenticeship objectives, focuses on practicalities and fundamentals of refrigeration, air conditioning and heat pumps to help apprentices develop their careers.

The new apprenticeship, co-launched by ACRIB, the Institute of Refrigeration and employers as part of the national apprenticeship objectives, focuses on practicalities and fundamentals of refrigeration, air conditioning and heat pumps to help apprentices develop their careers.

The ‘RACHP Engineering Technician Trailblazer Apprenticeship’ is a Level 3 training scheme which takes three years to complete. Its designers describe it as the ‘new standard on fundamental scientific principles and the application of knowledge’ for the industry. The new apprenticeship will provide national and professional recognition for the individual when they the qualify.

Employer Recognition and Involvement

Importantly, the new ‘Eng. Tech.’ qualification ensures employers have a vested interested in bringing new entrants into the RACHP industry through government funding.

Employers, such as Sainsbury’s, Carter Synergy, Star Refrigeration, Space Engineering, Daikin, Mitsubishi Electric, Adcock and Integral, have got behind the apprenticeship to help them fill skills gaps in their businesses.

The government is supporting the scheme with funding through its national apprenticeship scheme. Employers have to contribute a third of the cost for the three-year scheme, the cap for which is £9,000. The government will fund the remaining two-thirds (i.e. up to £6,000).

Work On Anything, Practically

To gain the qualification, apprentices have to be ‘competent to work on any refrigeration, air conditioning or heat pump system [which uses] the vapour compression cycle.’ The group which designed the Engineering Technician apprenticeship for the RACHP industry have made it a very practical scheme, something which has been lacking, as far as employers are concerned.

Much of the apprentices learning will be ‘on the job’. In fact,

10_IOR.indd 10

the scheme is about 80% hands-on where apprentices will have to implement theories learnt with their employers and training organisations for real.

John Ellis, from Ellis Training, who is part of the team that brought the apprenticeship together, stated: “We have not really tested apprentices over many years to see if they can apply the basic principles.

“Application of skills and knowledge are essential. Having knowledge alone is too limited. Applying knowledge is fundamental.”

He continued: “We give people certificates but they only tell people they have passed an examination. And, that is not good enough. This is what the new apprenticeship scheme addresses. Employers have to be involved in the development of the apprentice.”

What do the industry training companies think about the new apprenticeship?

The ACR Journal contacted Stephen Benton FInstR of Cool Concerns for his reaction: “Our industry has needed to regain control of its own apprenticeship schemes for a long time. The Trailblazer process will allow us to return to a tried and tested method of training and assessing with the final

qualification being ‘signed off ’ by an industry panel of experts. The return of the pass, merit and distinction is a positive step forwards.”

Addressing the Skills Void

The RACHP industry has very few people coming into it with Level 3 qualifications in refrigeration, air conditioning and heat pumps.

Apparently, fewer than a 100 people a year reach Level 3. The designers of the new, Level 3 Eng. Tech. apprenticeship scheme hope to have around 500 apprentices a year qualifying once it is running.

Importantly, the final assessments of the Eng Tech apprenticeship, the so-called ‘End Point Assessment’, focus on an apprentice’s behaviours, as well as their skills and knowledge.

The aim is that apprentices will have developed communication skills, shown adaptability, taken responsibility and demonstrated self-motivation too.

Representing employers and Chairman of the industry group, ACRIB, David Bostock from Integral explained his perspective on the Eng. Tech.

“How do we attract the right people into our industry?

“Not by money. We need to show a higher position, show a clear career path, and raise the standards, recognition and status of apprentices entering the industry.”

The next scheme in the pipeline will be a Level 6, Higher Level Apprenticeship for European Design and Applications Engineers which will provide an Apprenticeship Standard for those recruited at the Incorporated Engineer level into the industry. The working group has had approval to begin work on the Level 6 scheme.

s an industry, we are fairly hidden from the ‘average’ person, who only notices the air conditioning or heating equipment we manufacture, install and maintain, when the weather makes it hotter or colder than usual.

Yet air conditioning engineers actually have a hugely important role to play in helping us all mitigate the effects of modern life on the environment.

There is now a pressing need to address rising fuel prices, climate change and energy security, and the UK Government is introducing tough legislation to help, but clearly, this can only go so far.

To make a real difference, everyone involved in the built environment has to work together to ensure that we all minimise energy requirement.

The country is facing stringent, legally-binding carbon reduction targets, and buildings of all forms currently accounting for over 40% of carbon emissions in the UK. If we can address the largest draw on energy - the way we heat, cool and ventilate these buildings – even the smallest improvement will have a significant effect in reducing total energy consumption and help to lower bills.

Simplifying the Controls

As the industry responsible for this equipment, we have a key role to play in ensuring that it is designed, fitted, commissioned, and maintained to deliver the most effective and efficient system.

Part of this process lies with us as the manufacturer finding more ways of increasing the efficiency of the equipment. We also need to constantly look at simplifying the controls for systems, so that end users can simply get the best out of their kit.

Up to Speed on Energy Saving Technology

A large part though lies with you the installing engineers, who not only need to be completely up to speed on the latest energy saving technologies, you also need to be fully supported throughout the process from design-stage to customer handover.

Certainly that’s what we try to deliver on our training courses and I think it is vital that we all now approach our jobs with this energy reduction, planet saving philosophy in mind.

CHALLENGE FROM

THE CHINESE Global air conditioning giant Gree is set to challenge the status quo in the UK air conditioning market with the launch of Gree UK Limited.

P

art of the London-based Calibre Services Group, Gree UK will supply the manufacturer’s full range of splits, VRF, heat pumps, chillers and award-winning photovoltaic-powered systems across the UK. The company has already secured orders with national air conditioning specialists and has many active enquiries in the pipeline for major projects.

Gree is the world’s largest air conditioning manufacturer, with sales of more than £16bn and employing more than 8,000 research and development engineers in 570 laboratories and five research institutes across the world.

The company’s success has been built on a continuous stream of innovation, resulting in more than 20,000 technology patents, nearly 7,000 invention patents and some 300 million users of its air conditioning systems worldwide.

Roberto Mallozzi, managing director of Gree UK Ltd, said: “In a lifetime of experience in this industry, Gree is one of the most impressive and innovative air conditioning manufacturers I have ever encountered. The name may not be that well known in the UK at present, but that is something we intend to change.

“One in three air conditioning systems produced in the world today

Roberto Mallozzi

Gree R&D facility

is manufactured by Gree, a measure of the company’s commercial success and seriousness as a global player. The fact that Gree makes units for most of the world’s premium air conditioning brands says a lot about its quality credentials and approach, and its high standing even among competitors.”

Gree’s range covers all main air conditioning and heat pump technologies, from mobiles and small splits for domestic and light commercial applications, through VRF heat pumps, up to large centrifugal chillers with several megawatts of cooling capacity.

The company is investing heavily in the development of renewable and energy efficient systems. Its pioneering PV-powered, inverter-driven centrifugal chiller has won a string of awards for its ability to generate cooling from sunlight, and feed power directly into the grid.

Gree UK is backing the launch with substantial investment in stocks for immediate availability, a comprehensive spare parts service and a generous warranty scheme giving buyers peace of mind.

Gree UK has its own dedicated sales, technical and administration headquarters near London, and is currently recruiting additional staff for support positions. It includes a showroom and full training facility to demonstrate equipment and train engineers to install and commission Gree technology.

It is planning to install working examples of PV-powered cooling systems, to Continued on page 16

anopen and CLOSED case Buildings that have high levels of insulation can lead to the legionella thriving.

Here, Anthony Barnett, Marketing Manager at Armacell, looks at ways to reduce the risk.

“

ON AVERAGE THERE ARE AROUND 15,000 LEGIONELLA CASES EACH YEAR.”

L

egionnaires’ disease is a severe pneumonia caused by the legionella bacterium. People are most commonly infected when they inhale aerosols from a contaminated source. These fine sprays are created by heating and plumbing pipework, air-conditioners, swimming pools and whirlpools The bacteria multiplies where the water temperature is between 20-45°C and nutrients are available. As more insulation is incorporated into building designs it can result in cold water pipes warming above 20°C and in these situations legionella is a risk. When this is combined with extended periods of stagnation it results in optimal conditions for bacteria growth.

Traditionally, flushing systems have been used to beat legionella, although this is water intensive and relies on personnel carrying out the task on a regular basis.

Summer presents peak conditions for growth of legionella bacteria because during the holiday period water stagnates and super-insulated buildings, combined with improved air tightness, cause internal temperatures to soar, making cold water pipes an ideal breeding ground

Armacell.indd 20

for this hazardous bacteria. Elderly people are usually worst at risk of legionella or those who have pre-existing conditions, such as diabetes, lung or heart disease or have problems with immunosuppression.

That makes it a particular concern in multi residential homes as well as hospitals and schools. On average there are around 15,000 legionella cases each year.

CHECKLIST ₀ The temperature of hot drinking water pipes should not fall below 55°C ₀ The temperature of cold drinking water pipes should not exceed 20°C ₀ Hot and cold water pipes should be laid a sufficient distance apart to prevent temperature transfer ₀ When installing pipework, ensure that there is enough space for insulation ₀ Only closed-cell insulation materials should be used on cold water pipes to prevent condensation and energy loss ₀ The insulation thickness on cold pipes should be roughly equal to the pipe outer diameter.

Insulate hot and cold pipes

One of the most effective preventative measures for reducing the risk of legionella is to insulate both hot and cold water pipes with suitable materials such as closed-cell insulation. That is because poorly chosen insulation can lead to the HVAC system operating in optimum conditions for the bacteria, which usually means the ‘cold’ water temperatures regularly rising to above 20°C, although poorly insulated hot water pipework could also create the same conditions if temperatures fall below 45°C. There are a number of steps that heating engineers can take to maintain water temperatures at a level that doesn’t support bacteria growth.

In terms of pipework layout too, there are some simple steps that can be taken, such as ensuring that pipes for cold drinking water don’t follow the same routes or run adjacent to space heating or hot water pipes. Cold water pipes should also be protected against heat gain by ensuring sufficient clearance or, preferably, by insulating properly. Similar requirements apply for hot water pipes to protect them against heat loss.

If hot and cold pipes are laid in one duct or wall cavity, or wherever water is not circulated regularly, we recommend using what is known as 100% insulation.

That is where the insulation thickness roughly corresponds to the pipework

Armacell.indd 21

outer diameter. For example, if the pipe is 22mm diameter, insulation thickness used would also be 22mm. This not only prevents legionella in hot water pipes but also protects the pipes against unnecessary energy losses. For cold water pipes, the insulation provides protection against freezing in cold weather as well as providing protection against unwanted temperature rises.

Suitable insulation materials also prevent condensation. The best material for this is again closed-cell insulation, which has a high resistance to water vapour diffusion, making it ideal for use on cold water pipes where condensation is likely to occur. Plus, by preventing moisture ingress and providing no ready food source, closed cell insulation discourages the growth of microbes. AF/ Armaflex Class O closed cell insulation also has an additional anti-microbial protection built in, giving active protection against microbial growth.

Conversely, open-cell insulation materials, whether specified with or without a vapour barrier, do not

sufficiently prevent moisture ingress as a result of diffusion. This means that there is a danger of water vapour in the air penetrating open cell insulation, condensing and saturating the insulation material. As the material becomes damp, its thermal conductivity increases and insulation properties deteriorate, causing greater energy losses, and a greater risk of hot water pipes creating conditions for legionella bacteria. Furthermore, corrosion and other expensive consequential damage can occur.

Contaminated air-conditioners, showers, drinking water, swimming pools and whirlpools are well-known sources of Legionnaires’ disease. However, the root cause is commonly errors made in the choice of insulation. One of the most important preventative measures to avoid this potentially fatal disease is to insulate hot and cold water pipes with closedcell insulation.

Everyone wins

Plant owners like reducing running costs, contractors who save their clients’ money win favour, and everyone benefits from lower global warming effects by reducing CO2 emission from power production.

The F-Gas Regulations were introduced to limit leakage of high GWP refrigerants.

However, the CO2 released from the production of power used by refrigeration and air conditioning systems contributes far more to global warming than the direct leakage of refrigerants.

So why aren’t all fridge systems as efficient as they could be?

Market forces and lack of knowledge

Alan Jackson, BJA Refrigeration Consultants

Saving Energy in Refrigeration Systems

IS A WIN-WIN FOR EVERYONE

By Alan Jackson - BJA

BJA.indd 22

One answer lies in the effect of market forces. Suppliers of refrigeration systems need to win projects to survive so are tempted to offer the lowest capital cost systems to get the order. This invariably means skimping on the selection of components and system designs. Energy efficient systems almost always have a higher initial cost. Many end-users do not have a technical understanding of the relative merits of different refrigeration systems so they are ill-equipped to make value judgements about which system would be best for them in the longer term.

Even when a contractor offers an efficient system and explains the benefits they may not be believed or the purchaser may not be able to afford his plant.

Another reason many systems do not work as efficiently as they could is a lack of understanding among some refrigeration engineers. For instance, there is a common belief that it is necessary to maintain artificially high head pressures even though there are thousands of systems working perfectly well with lower ‘floating’ condensing temperatures. Every 1°C condensing temperature that can be reduced can save around 3% energy.

Maintenance can significantly reduce energy consumption

A lack of maintenance of systems causes excessive energy use. If air-cooled condensers are not kept clean the condensing pressure can rise significantly leading to high energy consumption.

End users may not wish to pay for and engineer’s time if the plant appears to be

working OK and their product is cold but it could save a lot of money by reducing their electricity bill.

To improve the energy efficiency of the average refrigeration system there is a need to improve the understanding of all concerned with buying, maintaining and operating them. This is never going to be easy. A low capital cost for a new system is always going to be attractive to a client and a man whose job is making and selling food products will see learning about the efficiency refrigeration as being low on the list of important things he needs to do, and the refrigeration industry’s main

aim is to sell goods and services to the user and if the user wants a cheap system that is what they will sell.

However, it’s not all gloom. Having tried to sell efficient systems against cheaper ones for nearly 40 years, in the past 5 years I have found a growing interest in energy saving by end users. Perhaps it is high energy prices, perhaps is a growing awareness of global warming but should all encourage this interest and do our part in informing the user of the benefits of buying the efficient plant.

After all, as I said at the start of this article - it is in everyone’s best interest.

HEAT RECOVERY: GEYSER THERMAL HELPS HEALTH CENTRE WITH HEATING 2016

NACRHPA_WIN_HC logos for print.indd 1

Lolli Olafsson

Geyser Thermal won the ‘ACR Ancillary Product of the Year’ in January for its heat recovery system in a health centre which provides hot water using heat from an air conditioning chiller.

Will Hawkins met Lolli Olafsson to see the system in action.

04/02/2016 10:10

The Geyser Thermal Heat Recovery Unit

L

olli’s client was looking for a solution to lower their energy use and costs, and was open to alternative solutions.

His heat recovery system is as about as simple and effective as you can get, he said, when I saw the unit installed at the Nuffield Health Centre in Hatfield. That’s a good thing. There are no moving parts bar a small pump to move liquid around the system. It is low-maintenance too, almost ‘fit and forget’, it is that reliable.

Geyser Thermal give a lifetime guarantee on the system, they are so confident of its effectiveness and reliability.

The unit in the health centre takes heat

from the air conditioning unit outside and pipes it back into the hot water system (the hot water tank for which is located in the plant room nearby). The hot water is used for the showers. It is a good solution for the gym where they have a lot of hot customers working out who then need a good shower after their exertions. It is also ideal for pubs, schools, hospitals and buildings containing lots of people.

The heat recovery system saves the health centre £800 a month in energy, which means it will pay for itself within two years. Since its installation, the Geyser Thermal system has saved over 168 megawatts of electricity.

The close proximity of the hot water tank is a bonus for the heat recovery system. If the chiller had happened to be on the roof, then it is more challenging laying pipework around the building. But, Lolli stated, the Geyser Thermal system will work with around 90% of systems in operation in the UK. Often, consultants are reluctant to work with heat recovery systems, but Geyser Thermal’s solution is proving its worth through its simplicity and efficiency.

Heat recovery technology is not as ‘sexy’

The hot water tanks

as some renewable energy solutions, and does not attract government incentives.

Nevertheless, good heat recovery systems, like that of Geyser Thermal, make use of energy that you have already paid for, twice, at least. But, when the payback is so quick, you don’t need a subsidy for it to work.

Get in touch with Lolli. He will happily show you the data backing up how his heat recovery system saves money and energy. You will see why it won an award.

This month we take an in-depth look at the New VETO PRO PAC Tool Bag range.

ith prices ranging from £44.00 for the small meter bag up to a whopping £199.00 inc Vat for the laptop rucksack, we ask, “Can any tool bag be worth paying that kind of money?”

First and foremost these bags maybe expensive, but I have NEVER seen a tool bag built to this high standard in the 37 years I been in this industry.

They simply ooze quality, from the minute you pick up any of the Veto bags you realise immediately the materials they use to construct them are all first class. The waterproof base, weatherproof nylon body fabric, heavy duty plastic zips with oversized zip tabs, industrial strength nylon double stitching and marine grade rivets. They have really gone to town a delivered a superb quality tool bag. But let’s not get carried away, lets see what the review crew thought when they field tested these bags for a month.

The biggest surprise to me was that 50% of the review crew struggled to fit all their tools from their existing tool bags into the Veto Bag they chose to test.

If you intend to buy a Veto Bag then we recommend you choose the correct bag for your needs. Do your homework first, to avoid any disappointment.

All the Veto tool bags have too many small pockets that you’ll be hard pushed to find anything to put in them. It’s as if the bag designer thought “oh there’s a bit of space there, we’ll fit a pocket”. This is evident in the Veto Tech Pac, it could

Robs Review May 2016.indd 28

do with another row of screwdriver slots above the lower ones rather than all these little pouches and pockets.

The review crew loved the fact they could immediately see if anything was missing from the bag before they left site.

One thing became very clear, doing this review: most engineers carried more tools than they actually needed.

The 5 Year “Zero Downtime Warranty” Veto offer is very good. As long as you haven’t driven over your tool bag, stabbed screwdrivers through it or dropped it from a great height, it’s a relatively hassle free experience.

I was keen to speak to customers who had recently purchased a Veto Bag to see if they had trouble fitting all their tools from their old tool bag into the Veto and all of them said No. In fact, they were quite surprised when I mentioned the review crew’s concerns regarding the bags capacities.

That’s why we do these reviews. It is our job to give you as much information as possible about the products we review.

This should then enable you to make an informed decision before you make a purchase.

Veto Tool Bags are not for everyone.

Some engineers simply wont pay the high prices they charge. But for those engineers that do, provided you choose the bag that best suits your needs, you will not be disappointed.

I like the fact you can store your manifold in the front pouch. Love the hook to hold bag onto ladder grab rail whilst you climb up onto roof.

Could do with more vertical pockets rather than so many small zipped pockets.

This is a specialist rucksack designed for engineers carrying laptops tablets and paperwork, You keep the hook but lose the manifold pouch and sacrifice tool storage. A very engineer/job specific rucksack.

As an ex-service engineer the XL is my favorite.

Easy to see if tools are missing before you leave site. Carry strap included. Adding a centre storage pocket for manifold would improve it’s versatility even more.

Smaller version of the Tech XL, but great if your looking to have a go-to bag to store tools for specific jobs, such as maintenance work or commissioning engineer, that doesn’t need to carry loads of tools to site.

For those of you who like open tool bags you wont find a better quality one than the Pro Pac OT-LC. Good bag for both install & service work.

Comes with padded carry strap, that velcro’s to carry handle to stop it dragging in the dirt.

The MC is smallest and lightest of the bags shown on the top row, But perfect for job specific tool set up, such as test meters etc.

The TP4 is a mini toolbag that can be clipped onto the side of any of the larger tool bags shown above or carried via the detachable rubber handle. Makes a good diagnostics bag, as designed to hold a test meter and small amount of tools.

When I gave out all the Veto tool bags to my review crew this was the only bag they left behind.

The TP3 may be the perfect bag for someone. But for us it was simply too small to justify paying £44.00 for it.

The TP4 is a much better buy.

The Veto MB is a meter tool bag designed to be carried alone or clipped onto the sides of your Veto toolbag. I like the idea that you can create a modular tool bag system that works with you as and when you need it.

The MB2 is taller than the MB to accommodate larger meters, digital vacuum gauge and digital thermometers the MB and MB2 also hold a small amount of tools. I also like the PVC tape straps on all the small bags.

You could argue that having paid £200.00 for a tool bag it would hold ALL your meters without having to pay out another £55 to add more bags. But I know engineers that will and I fully understand why. Once you buy into the Veto range you will want to own more.

This month, the ACR Journal interviews Lisa Pogson, Resources Director at Airmaster.

Women in ACR.indd 30

After leaving school at 16, with a handful of GCSE’s, I earned an HNC in Business Studies at Rotherham College and subsequently, a Masters Degree in Management Resources from the University of Hull as a mature student.

Airmaster is a leading mechanical engineering services company which designs, manufactures on-site, installs and maintains bespoke, energy efficient heating and air conditioning systems for most market sectors across the UK.

What attracted you to the industry?

I joined Airmaster in 1995, having previously worked in the building industry. Initially, I worked in a part-time capacity to help out my future brother in law Richard (our MD) with admin and bookkeeping. As business and staff numbers grew, I took on a full-time role.

The diverse range of contracts that we were working on, particularly in the service and maintenance sector fascinated me.

What do you specialise in now and what types of projects do you work on?

I specialise in managing finance, HR, and internal operations, whilst being involved in overseeing customer service, and expanding our networks. We are currently undertaking ISO 9001 and 14001 certification and I recently spearheaded an investment in technological innovation and IT infrastructure that included replacing engineers’ hand-written job sheets with iPads. This saved money by massively reducing the time required to implement design changes between clients and the designer, and also resulted in a significant surge in the level of our customer service.

What do you know now about the industry which you wished you had known before?

I now understand that there is a whole science behind workspace planning. Thermodynamics is a fascinating subject. The importance and impact of natural light and ventilation on staff morale and services within a building cannot be overvalued. Air conditioning doesn’t have to be expensive and can actually be an efficient heating and cooling system if installed and used properly. However, it is integral to understand how all your building services work to help save energy and create a comfortable work environment to keep your staff happy.

What excites and interests you about the industry?

It is intriguing to see the way that the industry is responding to new technology and changes in refrigerants. I recently visited a Daikin factory in Plzen, Czech Republic and saw the production line first hand. The factory was so clean, tidy and organised, and really showcased how technology can complement efficient production. The construction industry’s continuing embracement of BIM is also very exciting, bringing flux and the need to constantly upskill.

Women in ACR.indd 31

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

I would tell them to aim high and not accept regressive gender roles within employment.

This year we are holding an International Women’s Day event in Sheffield City Region with the ATHENA award being sponsored by Airmaster. Culture is key to how a business will change and we need to be part of that. I am not keen on gender quotas to achieve this – women can be on boards on their own merit, they just need confidence and mentoring. Inspiring the next generation of women within this industry is one of my prime passions. I am PresidentElect at Barnsley & Rotherham Chamber and involved in the Chamber’s Women in Business group. I am also really proud to be a STEM ambassador, working with local schools and colleges to keep encouraging children into STEM subjects in school and university.

Where do you see your career developing?

Airmaster has witnessed substantial growth in recent years and have put some succession planning in place, with our Operations Director, Mark Staniland, and I planning to take the role of Joint MD later in the year. We are looking forward to opening a new chapter at Airmaster.

In 2017, Airmaster celebrates its Silver Anniversary – 25 years in business.

What are the challenges in this industry?

One of the biggest challenges for the industry is to continue to strive to provide technologically innovative air conditioning systems that are also ecologically sound. We promote energy efficiency through initiatives and services such as TM44 air conditioning energy assessments, expert advice on FGas compliance and close control air conditioning.

Airmaster has won the EcoStars award at Level 3 with plans already in place to achieve level 5.

We are also part of the Sustainability School, which promotes a sustainable supply chain.

Therefore, we only work with suppliers and manufacturers who have sustainability in mind such as the Carbon Trust accredited, Daikin UK.

What are the benefits of being in your role?

One of the major benefits of my role at Airmaster is the opportunity it enables me to aid and witness the professional and personal development of our staff. I am passionate about affecting positive change in young people’s careers. I want to ensure they become more employable and entrepreneurial - particularly those young people who may not have had many chances in life. I have led apprenticeships and developed colleagues to management positions. In fact, almost every employee at Airmaster and all senior managers started off in the industry as apprentices.

Mr Williams appears in a short testimonial video about the installation of the City Multi-Hybrid VRF system, which uses R410A refrigerant between the outdoor unit and a Hybrid branch controller box, but then uses water to transfer simultaneous heating and cooling around the building.

This means that it does not need leak detection equipment installed in occupied spaces and can save not only

“As an industry, we face a step change to the type of refrigerants we can use in the coming years”, explains Mark Grayston on behalf of Mitsubishi Electric. “We can either use refrigerants with a lower GWP value or use less of the existing ones and this is the approach we’ve developed with the HVRF”.

on installation costs but also on-going maintenance costs.

BS EN378 is currently best practice for refrigerant-based air conditioning when it is installed in a building with occupied spaces, such as hotels and smaller meeting rooms.

The standard will not only help minimise the risk to health should a refrigerant ever leak into a room, it is also part of the drive towards refrigerants with a lower GWP (global warming potential).

The company has set up a dedicated website to enable anyone to discover the benefit of adopting a hybrid approach, which includes the video with Tony Williams.

Air conditioning installers and customers are invited to watch the video and join the discussion about the future of air conditioning by visiting hybridvrf.co.uk/contractors.

BUILDING AN AERODYNAMIC W

FOR FAN PERFORMANCE M Mike Cook from Pole Star Products and Dr Jun Yao from the University of Lincoln’s School of Engineering explain their research into achieving energy savings with fan and motor combinations.

etting the right airflow from a fan is critical to the overall performance of any refrigeration equipment.

Manufacturers run many exhaustive tests to ensure that the correct motor power, speed, fan blade diameter and pitch are selected to give the best overall performance for their piece of equipment. With energy saving EC (electronically commutated) fan motors, many companies are retro-fitting stores refrigeration equipment to achieve much improved energy consumption but are they fitting the correct fan/motor combinations in line with the original equipment design?

With fan exchange & compatibility in mind, Pole Star Products Limited enlisted the help of (MEng) Mechanical Engineering students at The School of Engineering, University of Lincoln, to build a test facility capable of producing accurate performance data and detailed fan curves.

Armed with this data, customers can be sure that replacement fans will give very similar airflow, as specified by the original manufacturer. Figure 1 represents typical fan components in service supplied by Pole Star Products Limited.

The School of Engineering at the University of Lincoln has developed a type of innovative research informed teaching method to support students for their industrial curriculum development by undertaking industrial challenging projects, i.e. liquid nozzle injection.

The state of art engineering facility further enhances the quality of school teaching/research.

Figure 1 New “State of the Art” Engineering and Science Facility

Under the guidance of Dr. Jun Yao, a specialist in computational fluid dynamics and Dr. Rebecca Margetts, an expert in dynamics and vibration, the 4th year Masters students Jordan Westoby and Samuel Ward have developed a small sized subsonic wind tunnel/test rig, which can meet the requirements of airflow measurement requested by Pole Star Products Limited.

The fundamental of wind tunnel design concept is acquired from international standards set up by American National Standards Institute (ANSI) and the European ISO standards. Figure 2 illustrates the wind tunnel/test designed

to thoroughly test new products (specifically EC fans) ensuring that they meet the specifications of the original cabinet manufacturers. Working with the University of Lincoln’s School of Engineering students enables them to put into practice some of the theories learned and helps them to “get a feel” for working in industry.

The open circuit axial-flow fan type of the test “Rig” is constructed from clear Perspex with Pitot rings mounted in 3 locations around the “Rig” to monitor the pressure distributions.

Air settling means are installed inside the main chamber and an air damper fitted to the outlet to adjust internal pressure. Using a transparent material in the design enables the students to introduce “Smoke” which will give the students the chance to visually study airflow movement. Installed fans will also be monitored for electrical performance to give accurate power consumption.

On completion of the wind tunnel/ test rig experimental measurements, Computational Fluid Dynamics (CFD) will be employed to quantify detailed flow structures for the wind tunnel system and performance assessment.

Conclusively, the new facility will give Pole Star Products the ability

KEY ROLE FOR

LEAK DETECTION A-Gas Managing Director John Ormerod, on the technologies the industry is using to sharpen its game in this area.

L

eak detection is one of the key planks in ensuring that the F-Gas Regulations will achieve what is expected of them. With the refrigerant quotas starting to bite, making sure that a system doesn’t leak has never been more important. If a refrigeration system doesn’t leak, clearly you save money not having to top it up.

economical solution for the HVAC industry.

A hydrogen/nitrogen based leak detection mixture can deliver a non-flammable, nontoxic, safe and highly effective solution.

As we move down the curve to lower GWP refrigerants, working with flammable and mildly flammable refrigerants will become unavoidable. Up until now, a system running on non-flammable refrigerants has been viewed as desirable in terms of safety and the cost to the end user, but with the introduction of flammable and mildly flammable refrigerants, having an effective leak detection regime will now grow in importance.

Fast-moving hydrogen is one of the smallest molecules, enabling it to move rapidly through the system and to locate leaks quickly. Using a suitable detector, this provides an effective method of tracing leaks up to 100 times more sensitive than bubble spray. It has also been proven to be more efficient than other trace gases such as helium.

Trace-A-Gas® from A-Gas is a leak detection system with a five per cent hydrogen and 95 per cent nitrogen mixture.

Case studies have shown that by using this, leaks can be detected in the smallest of quantities and very quickly. This means, that engineers can sleep at night knowing they have done their very best to ensure a system is not leaking.

Robust Leak Detection

The key to success is employing best practice, which some engineers are already doing. Employing robust leak detection becomes even more important with new installations, as you will have to take a closer look at how you detect leaks.

Relying on pressure or vacuum decay, or using bubble spray is no longer the most efficient way of detecting problems in systems that leak. There are now far more sensitive methods that you can use.

Trace gas technologies were for many years the preserve of the nuclear and aerospace industries, but with the increasing availability of low cost detectors, this method can provide a high-tech and

THE FOCUS ON LEAK REDUCTION ALSO MEANS THAT THE INDUSTRY IS NOW HAVING TO UP ITS GAME REGARDING WHAT IT DOES, WHEN LEAKS ARE DISCOVERED."

All Areas Tested

This kind of technology can test all areas of a system, including insulated or difficult-to-access pipework. It also means that engineers have to spend less time on site and it helps reduce costs by avoiding re-work.

Not only will the adoption of this technology result in the efficient detection of leaks that were previously considered impractical, it will also help to reduce the effect of the HVAC industry on global warming and the ozone layer.

The focus on leak reduction also means that the industry is now having to up its game regarding what it does, when leaks are discovered. It is no longer acceptable from a legal perspective to allow a system to continue to leak and do nothing about it. Recording what action has been taken and where the leaks have been found is crucial.

CO2 Equivalent Calculations

The legislation that came into force at the beginning of last year set the industry the task of leak testing based on CO2 equivalent calculations, rather than kilograms in a system. It also demanded follow-up checks from as early as 30 days to ensure that the work had been successful.

The law also requires accurate F-Gas log books. Traditional methods of refrigerant reporting are time consuming and have required a large paper trail. With this comes the added burden of endless filing and the risk of losing paper copies.

Online technology can now monitor systems that leak and record this information at the touch of a button.

More mportantly this can be carried out while the engineer is out of the office by using a mobile phone or tablet.

AGAS.indd 37

Keeping Track of Refrigerants

A-Gas has employed 20 years’ experience in refrigerant reporting, leak testing and cylinder tracking to find an alternative to the paper trail. By talking to industry experts, distributors, engineers and end users it was able to develop Gas-Trak Online™ (GTO), an app which provides a simple way of meeting F-Gas compliance.

The F-Gas regulation requires that fixed air conditioning or refrigeration equipment containing F-Gases is listed on a F-gas Register. The app is able to log all refrigerant use and summarise the data in a unique online F-Gas log-book. The app’s GWP calculator will calculate the CO2 equivalent of refrigerants for you and track refrigerant cylinders.

Improved leak detection is very much a part of the F-Gas Regulations and will have an increasing influence on the industry. Some engineers are already sharpening up on leak detection and I am impressed by the way, that they are now adopting trace gas and online technologies to achieve this. Improved leak detection forms part of our rethink on the lifecycle performance of systems.

This is a key factor for customers and engineers and we are now getting better on leak detection as this more holistic approach in managing refrigerant use is adopted.

PART TWO

In Part One of Advanced Engineering’s guide to the perfect service of an external air conditioning unit, we looked at initial visual inspections, general housekeeping and internal maintenance and leak checks.

Now the focus switches to the heat exchanger and external leak checks.

Cleaning the heat exchanger

Dirt that accumulates on the coils comes from airborne particles, insects, leaves, etc. which in conjunction with the high temperature of the coil can become ‘baked’ on and prove very difficult to remove unless you’re using the right cleaner.

Advanced Engineering.indd 38

Evaporator coils before and after in one shot

So called “mechanical cleaning” using a brush or other tool is a good first step, but to clean the coil thoroughly you should consider a chemical cleaner. They cost pennies and the difference compared to mechanical cleaning can be profound, especially when it comes to maximising the unit’s efficiency and extending the period between services.

While there are products available that are environmentally friendly, for stubborn deposits you may wish to use a more heavy duty solution like SuperClean.

R CONDITIONING UNIT

Apply a protective coating to ensure long term corrosion protection This is a simple step that’s easy to do and can save you a great deal of time, effort and money in the long run. Use a good protective spray like EasyCoat, which is an acrylic protective coating for coils that has an indicator dye so you can ensure complete coverage. It dries quickly so this shouldn’t take long.

This is particularly important if the unit is near the sea. Due to the high levels of salt in the air in these environments, the aluminium fins can become corroded very quickly which will affect the unit’s ability for effective heat transfer.

External leak checking

It’s now a good idea to leak test all accessible joints, both primary and secondary seals, in accordance with EN 1516/2007.

Replace face panels

When replacing the facia panels ensure the casing fits correctly and snugly. Turn the unit back on at the isolator to make sure it functions appropriately.

Advanced Engineering.indd 39

You then want to check for vibrations, so operate the unit and force it to come on cooling; ramp the heating up to check this.

Listen and look at the unit to check it sounds as it should, and ensure the compressor or fan is not vibrating on bouncing on its brackets.

Final checks

Now it’s time to ensure all sealing caps on connections to the refrigeration system are replaced. There will be two connections, one on the high side and one on the low side (they have valves on them and plastic caps).

Engineers can use existing caps unless they’re worn or have deteriorated, but it is a good idea to invest in tamper-resistant security caps.

Spanner-operated security caps prevent a member of the public from opening and venting the unit maliciously (like a car or bike tyre), and they also act as an extra level of security if the valve fails.

Visual check and completion of the F Gas Label

And finally, check the panel and complete the F Gas label, documenting the service

and any leak checks. It is also a good idea at this point to perform a leak check of pipework with the system running.

Focus on flared joints, as these are mechanical connections, and braised joints (again, you may need to move insulation out of the way). Engineers should also detail the weight and gas in the system on the F Gas label.

Before you leave, simply clean the fascia and case, remove any grease, fingerprints or grime using with a finishing case cleaner like EasyFinish.

Prioritised Comfort

WITH HUGE SAVINGS! Matrix Energy Solutions superb Viessmann installation demonstrates why it deserved to be the Winner of the Domestic Air Source Project 2016, held at the Town Hall, Birmingham, in January.

W

hen the Davies family approached installer Matrix Energy, they had an even greater than normal need for reliable heating and hot water system due to their son’s 24 a day care needs.

The family also required their two storey barn conversion to be future proofed against rising fuel prices, and for it be as carbon neutral as possible.

Gatton Barn Farm had previously been an open barn without insulation or a heating system. The conversion saw it become a living area, care facility and home for the four members of the Davies family, with additional space for two carers who live permanently on site.

The close proximity to wildlife, trees and ground shading, meant air source heat pump technology was chosen rather than a ground source. The choice also fitted with Mr Davies requirement for a delay free installation, as it avoided the necessity of planning permission.

As well as seeking a system for low carbon emissions, the Davies family prioritised comfort as a key factor for the project, due the amount of time Daniel spends on the floor. The system also needed to have intuitive controls – switching the best available technology whist being robust and reliable.

Several technologies were considered for the site in the initial consultation. Oil was discounted due to it not maintaining the sustainable theme of this site, whilst biomass was also discounted due to the access issues for fuel delivery.

Ground source heat pumps were considered for the project, however

Matrix.indd 40

ground shading and wildlife issues prevented this from reaching the performance standards required. This meant that air source heat pumps, supplemented by solar thermal and PV technology was the most viable option for the site.

70 Percent Savings!

Matrix Energy designed and installed a renewable heating system comprising of 2 Viessmann Vitocal 350 – A 14kw air source heat pumps, a Vitocell 30 cylinder 300L and 2x40 sets of Vitosol 300-T solar thermal tubes. Each governed by the Vitotronic 200 controls, which decides which energy source is best used any time.

The energy gathered from the solar thermal tube collectors, located on the properties roof, feeds into a hot water cylinder during the day, whilst the air source heat pump provides continuous hot water for the underfloor heating of the 18 rooms.

The 28kW delivered from the two heat pumps covers the demand for heating and hot water of the main house and the lodge, easily offering a comfortable environment while lowering running costs. In fact, Gatton Farm Barn costs less to run that the owner’s previous three bedroom detached property. In comparison to an oil fired system, this is a saving of around 70 percent per year, equating to £5700.

Dear Paul,

Just a quick note to say a well-deserved “thank you” for what you and your company have done for my family. The renovation to our 400 year old barn and surrounding farm buildings has been a resounding success and a year on I cannot believe we actually live here. The solution we were looking for was a tailor made solution to meet our family’s entire needs. You made it easy for to understand each option fully and therefore the decisions we made were fully informed.

Added to this, it’s comfortable and flexible to meet all our needs including that our youngest son who breathes via a tracheotomy and suffers with a circulatory condition. This limited us to certain types of heating systems and the fact that we spend a lot of time on the floor playing with him is marvellous as the underfloor heating, both upstairs & downstairs, is so comfortable.

Because of our sons condition it was of paramount importance we installed a reliable system for medical needs. We have been through 2 winters now and have complete confidence in the system….”

Ground Source Heat Pump WINS GEOTHERMAL AND DIMPLEX AWARDS Geothermal and Dimplex do it again… read on about how they’ve won the Domestic Ground Source Project 2016, held at the Town Hall, Birmingham in January.

T

homas Vaughan, Managing Director of Geothermal says “When you get shortlisted it is very good PR but if you can win an award it gives the company very good credibility. We also won another heat pump category in 2013 for our commercial monitoring systems. Over the years we’ve put forward 12 different entries and am pleased to have been shortlisted as well as win on the night.

“The collector design in this installation pushes out the boundaries beyond industry standards in which we are achieving higher than normal CoPs. We have even improved on this design since within some commercial installations.”

Alan Bell, owner of the house situated in Kincraig, Scotland approached BRE Scotland in August 2014, looking for a recommendation for a company to install a ground source Heat-pump, using a Burren (river) beside his house, as the heat source.

Built 20 years ago, this house was very forward thinking with high levels of insulation and under floor heating. It was heated with an oil boiler existing heating system comprised of a 15lt copper cylinder and an open vented system with expansion above.

GEOTHERMAL.indd 42

Why this solution?

The oil usage records for the previous 3 years were obtained, to establish that the actual energy consumption of the building was. The run times of the existing system were calculated, resulting in the monthly and daily requirements of DHW used for the year. Records of the water temperatures of the Burren for the past 5 years to establish the lowest water temperature available as a heat source.

The Burrens water levels were also monitored, to establish the low level flow

FIGURES During sub-zero temperatures the lowest flow temperature from the collector was 4.9˚C An external temperature of 1.5˚C had a collector flow of 5.1˚C An external air temperature of 8.6˚C resulting in collector flows of 8˚C The average flow temperatures achieved have a COP of 4.5 with heating water flow temperature of 40˚C

rates. It was also proven that the Burren had not frozen over in the previous 20 years. It was at this point, when all the above data had been calculated, that an average water flow temperature of 2.5 degrees C and a COP of 4 at W35 was achievable.

We decided to install a Dimplex S1H11ME , which is a high temperature HP. Due to the design parameters it was pertinent to install a system that would achieve a higher COP than a normal temperature HP. The installation is currently on target to make a saving of 5.47 tonnes of Co2 per year.

What was installed?

₀ 2 x Kw energy meters on the hydraulic side ₀ 1 x electricity Kw energy meter installed on the power supply ₀ Temperature sensors on the HP flow and HP return

₀ Sensors on the DHW temperature and Collector temperature - where data is extracted from The installation was situated in the basement, alongside the existing boiler, which meant it was ultimately designed as a bivalent system.

Key Milestones and Timings

The complete install was set up to be complete in 10 days. However, due to unusually heavy rain, the water level rose from its normal level of 1 meter to over 2 meters. For safety, it took an additional week to ensure the safety when installing the Collector.

Geothermal have a policy of ensuring clients are without hearing or DHW for no longer than 4 hours, during installation. So they complete installation and switching off of the existing systems happens in the early part of the days, allowing the integration of the existing system to be carried within the shortest possible time.

How does it work?

The client, and his local plumber were given a short run through on the day of implementation. This explained all the settings that were recommended.

The filters are shown, to allow for basic maintenance requirements.

Five days later a call is made for another run through, just in case the client needs any adjustments to suit their specific needs.

The customer’s feedback

The customer is delighted with the HP and the installation. The boiler was only required for 35 hours throughout the cold Scottish winter. The house is extremely comfortable, and operates with flow temperature which is 10 degrees lower than the previous system.

After 2 months, an inspection was carried out to ensure that all settings were being optimised for achieving the highest COP. Filters were cleaned and flow rates are checked.

There was a small amount of air getting trapped in the collector, due to the fact the collector is a slinky. A slight increase in operating pressure moved this air and the efficiency when even further improved.

Having monitored the system over the winter, it’s proved to be performing event better than anticipated and such are getting even better heat transfer than the industry norm.

Monier launches self-adhesive HVAC pipe wrap

Hitachi Releases Lowest Noise Level Mini Cassette

WRAPTEC from Monier is a universal, self-adhesive cladding and jacketing material used to weatherproof HVAC pipes, ducting and insulation.

Its backing welds to the facing on laps giving a watertight bond which withstands the harshest weather conditions. With no need for primer, adhesive, sealant or heat activation, it is a quick and cost-effective means of preventing corrosion under insulation (CUI) at the duct pipe and ideal for detailing work and irregular surfaces. WRAPTEC can be cut by scissors and stretched up to 50% in either direction without loss of functionality.

Rolls are available in 4 sizes from 70 to 560mm.

Hitachi Air Conditioning Europe has a new mini cassette which has the lowest noise level on the market, the company claims. The Hitachi’s new RCIM FSN4 mini cassette range is the widest on the market, with capacities ranging from 0.6HP to 2.5HP (1.9kW to 8.5kW nominal capacity in VRF system heating mode).

The improved 3D twisted blade of the turbo-fan and the air outlet also achieves a very low noise performance; the 0.6HP to 1HP units noise pressure level is only 24.5 dB(A), the lowest on the market.

Its 620 x 620mm dimension has been reduced by 80mm compared to the previous model so it can be installed into a grid ceiling with a 600 x 600mm opening.

DAIKIN HELPS KEEP AIR AMBULANCES AIRBORNE Air conditioning and heating systems from Daikin UK are helping to keep air ambulance helicopters airborne across Essex and Hertfordshire.

The new Essex and Herts Air Ambulance Trust (EHAAT) head office in the Business Centre at Earls Colne Business Park, near Colchester, has a range of Daikin VRV, Split and Sky Air systems for climate control. A Daikin Altherma Low Temperature heat pump provides domestic hot water.

The Daikin systems provide a comfortable working environment for the Trust’s 30-strong support staff whose behind-the-scenes efforts ensure the vital life-saving service can continue to remain operational 365 days a year.

EHAAT is a Charity that depends entirely on business and public support.

EHAAT occupies 500m2 of a 680m2 block, newly built on the edge of a World War 2 airfield in Essex. The Trust’s section includes general offices, meeting rooms, staff room and an IT server room.

The Daikin systems were installed by appropriately named By-Air Conditioning of Colchester.

By-Air project manager David Newman says: “The main system has two VRV IV Heat Recovery condensing units which deliver a total of 73.5kW of heating. Indoors are nine

Chilly Chatter.indd 48

wall-mounted fan coil units in various capacities from 1.9kW to 4kW and seven Roundflow cassettes from 4kW to10kW. “The Split and Sky Air systems provide heating and cooling for the smaller rooms, including the server room, which is cooling only.”

All the systems are individually controlled by wired remote controllers which are easy to use and offer energy saving functions.

The Daikin Altherma LT heat pump is a shared system, providing DHW to the EHAAT offices and the adjoining offices.

Daikin systems were specified for the new development on the strength of a positive experience with Daikin equipment elsewhere in the business park, says Bob Ely, spokesman for the developer, E Hobbs Farms.

He says the Business Centre is the latest phase of the airfield redevelopment, which began in 1965 when Eric Hobbs acquired the 450 acre site, initially for farming.

“Development of the Earls Colne Business Park began in 1980. It now occupies about 40 acres of the site. The 18- and 9-hole golf courses, clubhouse and driving range occupy another 300 acres. The remainder includes the remaining active runway, roadways, grassland and wooded areas,” he says.
