Ask anyone in our industry about the lack of young people coming into the air conditioning, refrigeration and heat pump industry and they will agree that it is a problem. Not enough young people coming in to work as engineers and technicians means that businesses find it difficult to expand and fulfil customer orders. The belief is that our industry is made up of older men. If our website figures are anything to go by, the biggest group of readers is aged between 45 and 54 (26%, in fact). You might have expected that figure. But, still, there is the worry about the lack of interest from young people in becoming refrigeration, air conditioning or heat pump engineers. Or, is there a lack of interest? Over 30% of our readers online are between 18 and 34. That number might surprise you. It suggests that we have got a lot interest from young people in our industry. We just don’t know how to engage with them properly. There is a good initiative coming along this month to encourage young people into apprenticeships through the Trailblazer programme (more news soon on that topic). This is a positive step and will, hopefully, provide a clear pathway for young engineers looking for a career in our industry. Will Hawkins Editor, willh@warnersgroup.co.uk

DIVERSITECH BUYS PUMP HOUSE

BITZER OPENS NEW

INTERNATIONAL TRAINING CENTRE German refrigeration compressors manufacturer, Bitzer, opened its new, international training centre in Rottenburg-Ergenzingen, Germany recently. The 1,500-square-metre (16,145 sq ft) training academy took a year to build and was named in honour of the company’s owner, Senator Peter Schaufler , who died in 2015. Major changes in the air conditioning and refrigeration as a results of environmental and energy efficiency laws has made training an important part of helping customers keep up to date. The academy training is aimed at system designers, manufacturers and service engineers who need the skills to adapt to the changes in the industry.

The recent F-Gas Regulation and the Ecodesign Directive are driving refrigeration system manufacturers and system designers to rethink how they approach using less energy and reducing their impact on the environment. Bitzer Chief Technology Officer Rainer Große-Kracht said: “Thanks to our training, participants will be prepared for the challenges that they will face, and they will be able to practise working with new refrigerants and technology.” The ACR Journal will bring you more, exclusive details about the new training centre when we visit the site later this month. Find out more details about the courses here: www.bitzer.de/gb/en/ service/expertise/seminars

ARNEG MOVES IN WITH MANOR CONCEPTS

Arneg has moved its UK offices in with Manor Concepts in Sandy, Bedfordshire, the company announced this week. Arneg S.p.A. bought retail refrigeration cabinet and door manufacturer in 2015 and moving the UK operations into the same building made sense for the business. Manor Concepts MD, Michael Tucker said: “The new joint headquarters is a strategic move to strengthen the benefits of the merger for both companies. It will allow us to expand our existing product range offering as well as support Arneg UK with innovative product development.” The move will not affect how Arneg UK’s MD, Dennis Hall and his field sales team work with their distributors. The company is planning to open a new sales room in the Sandy headquarters to show the Arneg and Manor Concepts ranges.

CITY UNIVERSITY BENEFITS FROM WATERLOO AIR TERMINALS

GEA ANNOUNCES RECORD SALES IN Q4 2015

German engineering company, GEA, announced record sales for the last quarter of 2015. The firm achieved €1.240 million of orders (~£930,000) which is up 7.1% on its previous quarterly record of €1.220 million in Q4 2013. GEA makes a wide range of cooling and heating products for markets, including compressors, chillers, heat pumps and freezers. Their CEO, Jürg Oleas, puts it down to their staffs’ hard work and their customers’ trust in their products and solutions. He commented: “2015 was a very special year for GEA, as the group made a fundamental transition from an agglomeration of smaller businesses towards an integrated group, taking out complexity costs by reducing the number of management layers. While all this fundamental change was happening inside the company, GEA’s employees showed their real strength by staying focused on customers and markets to achieve the highest order intake ever in any quarter.”

Waterloo Air Products’ air terminals benefited City University when specified as part of the establishments’ recent renovation and refurbishment program. The university used the company’s grilles, diffusers and VAV systems in its Tait building which contains the Schools of Engineering, Mathematics and Health Sciences in Spencer Street, London. The designed had to look good as well as have good air flows. Waterloo chairman, Rick Edmondson said: “Good air distribution is pivotal when it comes to conditioning a space and correct specification can determine the efficacy of an HVAC system and the comfort of the building’s occupants.” Waterloo has done a lot of business in the education recently. Some of its recently projects in the sector include Imperial College, Brunel University, Manchester Metropolitan University. The Kent-based company has also worked in university hospitals in London, Salford and Manchester.

AIR MOVEMENT: MANSFIELD POLLARD ADAPTS TO NEW VENTILATION REGULATIONS Mansfield Pollard, the Bradford-based air movement solutions specialist, has made sure its ventilation solutions for non-residential applications now comply with the latest EU legislation on energy savings and greenhouse gases, the company announced recently. The European Union brought out new rules in July 2014 to force ventilation solution manufacturers to make their product more energy efficient and environmentally friendly. The new rules (EU No. 1253/2014) came into force on 1st January 2016 across the European Union, including the UK. Fortunately, Mansfield Pollard has prepared its product range to be ready for the new rules. Its bespoke air handling units (AHU) comply with the new design rules. The EU Directive applies only to nonresidential AHUs used in non-hazardous environments. All ventilation units have to meet a ‘minimum energy performance’. Mansfield Pollard sales and marketing director, Andrew Glen said: “We strongly believe that as an industry we have a

responsibility to design and supply air management solutions which are energy efficient and which minimise the creation of greenhouse gases. We therefore welcome this new legislation and are working with our clients to help them understand the implications of this change in the regulatory requirements. As suppliers of tailor-made air handling units we have designed many thousands of Air Handling Units to exacting specifications and this change in the regulations is simply another criteria to which we have to adhere.” The ACR Journal visited the awardwinning Mansfield Pollard in 2015 to see their air movement products being made. The company makes ventilation units for customers in the medical and healthcare sectors, as well as for clients in the catering, data centre and governmental sectors.

THERMOZONE ACHIEVES CARBON TRUST ACCREDITED SUPPLIER STATUS

ThermOzone, the Reading-based chiller remanufacturing and servicing expert, has announced that the Carbon Trust has given the company ‘Accredited Supplier’ status. The achievement is given to companies that clearly demonstrate the energy and lifetime cost savings made by their products. Given that only Daikin and Emerson have gained the status have achieved this accredited supplier status, it puts ThermOzone ‘s achievement into perspective. ThermOzone has two chillers brands, namely ReChill and NuChill, through which they help their customers upgrade and replace their inefficient units. The accreditation is a big boost for ThermOzone. The status backs up the companies claims about its chillers. It will give new clients confidence who need evidence that ThermOzone chillers will provide the return on investment that the company claims. According to ThermOzone, most of their chillers provide a two to three year return on investment. Some pay for themselves within a year. When customers are paying in excess of £400,000 for their chiller solutions, knowing that the data behind the claims from ThermOzone is credible will be a relief for customers who need to justify the investment.

CHINA STOPPED FROM DUMPING HFC REFRIGERANTS IN THE US

The US government’s Department of Commerce has published a report which states that China is dumping Hydrofluorocarbon (HFC) refrigerant blends in the USA at ‘less than fair value’ prices. The report also includes HFC components. The refrigerants in question include R-410A, R-404A. The components include R-32 and R-125. The HFC refrigerants are used in air conditioning and refrigeration systems. Chinese HFC imports into the USA increased by 80% between 2012 and 2014. The increase put pressure on US producers as they lost market share to the Chinese, and refrigerant prices dropped. As a result, US companies felt they were trading on unequal terms and that jobs were at risk. The department began the investigation into the ‘dumping allegation’ in July 2015 when pressure group, the American Hydrofluorocarbon Coalition and its members, submitted an antidumping petition protesting against the Chinese imports. After the petition was filed, Chinese producers and importers appear to have dramatically increased their HFC imports to avoid the ‘antidumping duties’ before they were enforced. The build-up of HFC refrigerant blends meant that the Chinese firms could trade at unfair prices. Department of Commerce officials decided that the duties on the HFC blends would be retrospective, meaning that Chinese producers and importers would have to operate on equal terms. The duties came into force on certain imports made after 1st November 2015.

Institute of Refrigeration ANNUAL CONFERENCE The Institute of Refrigeration held its annual conference at the NEC near Birmingham in February. Here is a summary of the event the theme of which was ‘Emissions, Energy and EcoDesign’.

opics included system design in the future as a consequence of the Ecodesign directive, end of life treatment for temperature exchange equipment, EN 378 changes and challenges, Ecodesign case studies, updates on emission reduction and a related case study.

Ecodesign

Judith Evans from Judith Evans, London South Bank University & Refrigeration Development and Testing began the conference sessions with a details about the Ecodesign and Energy Labelling Directives, their legal frameworks, requirements and their impact on the industry. The Ecodesign directive aﬀects manufacturers making and selling more than 200,000 units a year in a product segment within the EU. It has little impact on the size of the market and its structure, and appears to be positive

10_IOR.indd 10

for business. Ecodesign aims to deliver energy savings, to improve energy supply security in the EU, to create jobs and to help the community to reach its climate and energy targets. By 2020, Ecodesign aims to save 600 TWh/yr of electricity, 600 TH/yr in heat savings and €900 billion/yr in energy costs for consumers and business. To comply, manufacturers have to design and build products which meet the directive’s technical documentation, declare conformity and produce their own technical documentation. The type of products aﬀected include cooling and heating systems, ventilation products for both domestic and commercial markets. Judith pointed out that although there is little sign of policing the directive now, the recent scandal involving car-maker VW’s emissions, makes it likely that enforcing Ecodesign will become a higher political priority.

Temperature Exchange Equipment

Julie-Ann Adams from Really Green Credentials, spoke about End of life treatment for ‘temperature exchange equipment’ (WEEE) legislation, realities and operations. ‘Temperature Exchange Equipment TEE)’ is an EU term which covers domestic and commercial heating, cooling and freezing systems. The WEEE directive is about the re-use of materials used in TEE which have been discarded in the past. When a TEE unit comes to the end of its life waste management companies have to check which materials can be re-used, such as cables, circuit boards or gases. Not every material can be reused or recovered, however. The WEEE directive aims to have 85% of materials to be recovered from 15th August 2015 onwards, and 80% of it to be prepared for re-use and recycling.

LIGHTS, CAMERA AND SILENCE When the developers of a new film and photography studio in the heart of London’s Islington were looking to refurbish an old warehouse they needed to find an energy efficient way of heating and cooling the building that would also offer a whisper-quiet performance.

he contemporary interior design provides an extraordinary creative space which is now enjoying energy efficient air conditioning and ventilation after work by contractor 361 Degrees. The contemporary interior design provides an extraordinary creative space which is now enjoying energy efficient air conditioning and ventilation after work by contractor 361 Degrees. The refurbishment is full of beautiful features including original timber beams, floor joists and exposed London stock brick and the stylish installation of the air conditioning has added to the stunning interior, whilst delivering super quiet and efficient heating and cooling. 361 Degrees, who operate throughout the country, has matched this high standard with stylish metal circular ducting that delivers the levels of comfort and control needed from the system.

A film studio also needs whisper quiet air conditioning and the installation helps achieve the best environment for creativity. “The building is home to a number of photography companies, a production house, a fashion PR company and a high end retouching studio, so they need a comfortable, creative space”, explains Lewis English on behalf of 361 Degrees. “For the filming in particular, they also need quiet solutions from the heating and air conditioning and this is where the Mitsubishi Electric systems have proved their worth, with units through all four floors of the building”. A City Multi heat pump air conditioning system was used as the main heating and cooling solution with a combination of wall mounted and exposed ducted fan coil units in the varying rooms throughout the refurbished building. The Lossnay heat recovery ventilation system also means that energy is recovered from outgoing stale air and transferred to heat up the incoming fresh.

CLEAN AIR, HOW DO HVAC SYSTEMS COMPARE? Here, Mike Booth, European Marketing Manager for Air Treatment at Fellowes UK, discusses the results of a survey, commissioned by AeraMax PRO that reveals 9 out of 10 Corporate HQ’s have experienced indoor air quality issues.

oor indoor air quality can negatively impact on employee wellbeing, health and productivity, severely denting a company’s bottom line. Within the climate control industry, it is established that HVAC systems that are not properly serviced and maintained can become hazardous sources of air pollutants. In fact, the Center for Disease Control estimates that two out of three indoor air quality problems involve the HVAC system. As ventilation air ﬁlters become saturated, microbial growth and odour concerns occur. Stagnant water contained in the drain pans or moisture inside air ducts and cooling coils can become a breeding ground for microbial growth. This leads to poor indoor air quality and consequently sickness and absenteeism amongst workers.

Lost working days

Each year, more than 130 million workdays are lost in the UK due to sickness, costing employers a staggering £32 billion in lost productivity. The annual expense associated with absent employees is estimated to be £975 per employee. For a small enterprise of 10 employees, the yearly cost can be as high as £10,000. In a competitive economy of tight margins this can be the difference between turning over a profit or not. Additionally, figures from the World Green Building Council show that an improvement in indoor air quality can increase employee productivity by 8 -11%. Despite this, a recent survey, commissioned by AeraMax PRO, investigating the reality of facilities managers’ perception, treatment and monitoring of indoor air quality

Fellowes.indd 15

within a workspace environment has revealed some interesting and alarming insights. Of the 112 facilities managers who took part in the survey, 9 out of 10 viewed indoor air quality as an important issue. Despite this, only 5 out of 10 actually monitored it more than once annually, with 3 out of 10 never monitoring indoor air quality. Nearly all survey respondents admitted to experiencing indoor air quality issues and complaints, further reiterating how routinely the issue is marginalised.

IAQ rarely measured

Although, HVAC systems are periodically inspected for the purpose of increasing eﬃciency, these inspections rarely

measure indoor air quality. Consequently, the air that employees share in areas of high occupancy continues to adversely affect their wellbeing and productivity. There is still no legally binding requirement for facilities managers to improve the air quality of a building or areas of high foot traffic. Regardless of this legislative oversight, the provision of a comfortable working environment should be of primary concern for facilities managers, installers and specifiersespecially as products now exist which aid and complement existing HVAC and ventilation systems. One such product is the AeraMax PRO, which uses a four-stage filtration process, effectively removing particles as small as 0.3 microns. A HEPA filter (high efficiency particulate air), treated with an antimicrobial layer, captures 99.97 per cent of airborne particulate. An activated carbon filter adsorbs unwanted odours and VOC’s that can lead to poor air quality and a bipolar ioniser breaks down microorganisms and odours throughout the room, providing a cleaner, more hygienic indoor environment. Incorporating EnviroSmart Sensor Technology into a sleek wall mounted unit, the machine constantly monitors Continued on page 16

the room’s air quality and occupancy, automatically adjusting its performance to maximise the quality of the air whilst reducing energy consumption and extending the life of its ﬁlters. Indoor air quality is an issue of upmost importance. Facilities managers, installers and speciﬁers should adopt a more pro-active approach and comprehend that a sole reliance on HVAC systems

Fellowes.indd 16

to maintain good indoor air quality is no longer adequate. By implementing actions that improve indoor air quality, those employed in the building services industry will be ensuring a healthier environment for those occupying the buildings they maintain and service, as well as positively impacting on organisations’ bottom line.

Work begins on Armacell

FACTORY EXTENSION PROJECT Thermal and acoustic insulation manufacturer Armacell has commenced site extension works at their ISO 9001 and 14001 certified Oldham plant.

he capital investment program is scheduled for completion in April next year and upon completion will provide a large new logistics area and warehousing, including a one way access system for heavy goods vehicles visiting the Mars Street site.

When the work is finished, freight vehicles will park at a new covered despatch area, complete with automated loading bays and additional holding lanes. The new 6,300 sq m site is designed to create a smooth flow of traffic to the new warehouse building and will help prevent congestion on the surrounding access roads. The UK plant is one of 23 Armacell manufacturing facilities worldwide and a primary location for the production of the AF/Armaflex Class O, ArmaSound RD and Tubolit insulation ranges for HVAC-R, industrial process and heating and plumbing applications. Armacell UK has been based at the 26,400 sq m Mars Street site since the mid 1960s and the approved multi-million pound development plans represent a significant investment in improving the infrastructure and capacity at the premises.

New Extrusion and Milling Equipment

The new site layout will accommodate state of the art extrusion and milling equipment for the Armaflex range and the extension building will house Armacell’s value added manufacturing activities including ArmaSound production processes, new self-seal production lines, lamination activities and pre-fabricated fittings for pipe bends, elbows and t-pieces. The extension will also incorporate a new maintenance and engineering workshop and stores. The main office building is also being modernised, with wheelchair friendly access routes to the main reception and staff entrances and a new pedestrian walkway around the perimeter of the building currently nearing completion. New windows and shutters, roof canopies, access gates, bike parking, outdoor seating, re-painting and new signage will refresh the facade of the building, whilst new LED lighting throughout the shop floor and office areas completes the planned energy efficiency and access improvements. A currently disused building on the Mars Street site is also being renovated into a new office space for Armacell’s finance and admin team, enabling them to join the firm’s 100 strong sales & marketing, logistics and production staff in the main offices. The scheduled work follows on from the recent opening of a new technical application training centre at the Mars Street premises, equipped with new pipe, valve and ductwork demonstration equipment. Armaflex application training courses are held monthly at the new centre, providing accredited instruction for thermal insulation and M&E contractors.

Huge Financial Implications

FOR OWNERS OF REFRIGERATION SYSTEMS The F-Gas Regulations are going to extensively affect everyone who owns refrigeration systems operating with HFCs. HFC’s have been the refrigerant of choice since CFC/HCFC gases were phased-out due to their environmental impact.

By Alan Jackson, Director at BJA Refrigeration Consulting Engineers

FC refrigerants have a high global warming eﬀect so they too are now being phased out over the next few years and as a result most commercial refrigeration systems will become unmaintainable and need replacement. Owners of these plants need to plan for the ﬁnancial implications now.

There is an old Chinese curse – ‘May you live in interesting times’ EC Regulation No517/2014 came into force on 1st January 2015 and was enacted in UK law as ‘The Fluorinated Greenhouse Gases Regulations 2015 No

BJA.indd 20

YEAR % 2012 CO2eq 2015 100% 2016-17 93% 2018-2021 63% 2021-2023 45% 2024-2026 31% 2027-2029 24% 2029 21%

310’. The intention of the Regulations is to reduce F-Gas emissions as part of the ﬁght against global warming They achieve this primarily by restricting the amount of refrigerant produced or imported. This restriction is based on the CO2 equivalent of the gas. The table above shows how it is proposed to be reduced over the next 13 years, of course this might alter as the F-Gas Regulations are reviewed in the future. So far we have seen very little impact on the availability of refrigerants but

from this year the reduction will become increasingly noticeable. There will be 7% less gas available this year compared with last year and the requirement for refrigeration is still growing year on year. In less than 2 years’ time the amount of F-Gas refrigerant available will have been cut by 37% CO2 eq and in 5 years’ time the amount available will be reduced to less than half the CO2 eq quantity currently available. As the refrigerants become scarce be prepared for some very serious increases in refrigerant prices!

From 2020 sales of R404A will be banned entirely and it will be illegal to charge virgin R404A into a system. Well before then, it is highly likely that R404A will be extremely hard to obtain and consequently very expensive. So the only way to keep R404A systems operating is going to be to retrofit them with an alternative gas, probably R407F, R448A or R449A as this can be done fairly easily. This might give these plants another few years of use, providing they are kept leak free. From 2020 it will be illegal to fill new plants with refrigerants with a GWP higher than 2500. From 2022 it will be illegal to fill new plants >40kW with refrigerants with a GWP higher than 150. There are other parts of the Regulations that increase leak testing requirements and the increased requirement for leak detection systems, but the cost of refrigerants will make these highly desirable anyway.

Regulations

The cost of operating a system with HFC refrigerants will increase with a risk of shortage of supply. The reduction in ‘placing on the market’ will mean that refrigerant producers and importers are very likely to either stop producing or severely limit production of the high GWP refrigerants so they can produce more of the lower

BJA.indd 21

GWP alternatives. This is likely to dramatically increase the cost of existing high GWP refrigerants such as R404A, R507A etc. which in turn will drive a need to retrofit the huge number of existing R404A systems to use one of the lower GWP alternatives. This is likely to use up a significant proportion of the quota of refrigerant CO2 eq available and increase prices further. The cost of ‘topping up’ to replace lost gas will also drive an increase in work to find and repair leaks. There will be a general move away from installing new systems using HFCs. The alternatives choices will depend largely on the application, with industrial plants continuing to use ammonia and supermarkets probably using CO2 more extensively. The HFO refrigerants are also likely to become more widespread in smaller systems, in chillers and a/c splits. Hydrocarbon – glycol systems may also find favour with some users. Unfortunately, there are still many within our industry who as yet do not have the skills and qualifications to work with these refrigerants. That situation must change. There is bound to be a large number of both end users and contractors who are reluctant to change or think they cannot afford to. They may try to find ways around the legislation by using smaller plants so that the GWP 150 limit is avoided and by ‘re-building’ existing systems to avoid the 40kW limit on new installations, and then later there may be a change of evaporators

and piped services. The definition of what constitutes a ‘new’ system will probably be tightened up to control this. It will be the massively reduced availability of HFC gases that will, in the end, make these systems impossible to maintain. Over the next 5 to 10 years the Regulations will effectively make most existing systems unserviceable due to unavailability of refrigerant. Many of these will need replacing anyway due to their age. It would be very short-sighted to replace them with new HFC systems as the new systems will almost certainly need to be replaced before the end of their useful life. This will inevitably lead to the need to replace or very heavily modify virtually all existing refrigeration plant that do not use ‘natural’ refrigerants.

Implications for Plant Owners and End Users.

This massive expenditure that may run to hundreds of millions of pounds may not have appeared yet on plant-owner’s radar. They will not have budgeted for it. As an industry, it is important to forewarn them as they will need to understand the financial and practical implications. These changes are also likely to pose a problem for our industry through having insufficient manpower, skills and capacity to cope with the changes. Interesting times are coming!

HOW R32 WILL MAKE A DIFFERENCE A-Gas Managing Director John Ormerod on why this low GWP refrigerant is making its mark in the industry

here’s been much talk recently about the rise of R32 as a practical alternative to R410A in air conditioning equipment. With its low GWP (Global Warming Potential), this emerging HFC refrigerant is the focus of discussion among sections of the industry. R32 is already available from A-Gas through our wholesale partners in a variety of cylinder sizes and from a practical perspective it is a good replacement for R410A, a high GWP gas, which is affected under the F-Gas Regulations. From 2025 any gas with a GWP higher than 750 will be off limits in low-charge split air conditioning systems and this is where R32 will make an impact. R32 is a single component, zero ODP gas with a GWP of 675, significantly less than R410A, which has a GWP of more than 2000.

Flammability?

The cooling capacity of R32 is higher and there are considerable efficiency gains to be made from making the switch. A further bonus is that the equipment used needs a smaller footprint. R32 has an ASHRAE classification of A2L and is considered mildly flammable. Ironically, R410A is a mixture of R32 and R125 with the R125 suppressing R32's flammability.

AGAS.indd 22

John Ormerod

It’s early days for R32 and that’s because there’s still not a huge amount of air conditioning equipment able to use it. Some manufacturers have begun to supply equipment which is R32 ready but this is still limited in scope and it is fair to say that it is still mainly R410A-based kit which is today’s preferred option. If there is a downside to R32, it is the A2L limited flammability, and in the short term this could hinder it’s application. We certainly need clarity with the finalisation of EN378 before we can understand if VRF systems are suitable for R32 because of the quantities of the gas needed. Ultimately there is going to be a limit to the size of R32 equipment and this will be governed by the updated version of the European standard which is expected to be published this year. R32 has always been viewed as an effective refrigerant with good environmental properties but this has been tempered by concerns about its mild flammability. However, as the influence of the F-Gas Regulations has grown, R32 has become a talked about refrigerant in todays’ HVAC industry. Regulation, historically, has been very black and white on flammability – highly flammable or not with nothing in between – but these mildly flammable A2L refrigerants fall into a grey area.

Handling R32 Safely

Engineers need to be more aware of how to safely handle the refrigerant and ensure that they have the right tools for the job. The industry has certainly got to get its head around the fact that the current recovery units and vacuum pumps aren’t going to be appropriate. Manifolds and hoses for R32 are already on the market – and there are recovery units and dedicated recovery cylinders available oﬀ the shelf for use with ﬂammable products.

New recovery units, different gauges and potentially R32-friendly hoses will dominate the thoughts of engineers but for most installers switching to R32 should be a fairly straightforward transition. Talk to your equipment suppliers for advice on this. I can see R32 being a significant player in the years to come. Air conditioning manufacturers are clearly ahead of the regulations by starting to offer R32-friendly equipment now and I have no doubts that by 2025 the industry will have caught up.

To make it easier to recognise R32, A-Gas and equipment supplier JAVAC have joined forces to raise the proﬁle of the refrigerant and its related tools. All cylinders containing R32 supplied by A-Gas and its wholesalers, together with R32 tools and equipment from JAVAC, now carry a specially-designed R32 label. It is hoped that the rest of the industry will follow suit and adopt the label for all R32 products to make them easier to spot in the wholesale network.

“

IRONICALLY, R410A IS A MIXTURE OF R32 AND R125 WITH THE R125 SUPPRESSING R32'S FLAMMABILITY”

To highlight how the industry is changing, A-Gas will also be joining equipment suppliers Fujitsu and JAVAC to answers questions on R32 in a FREE webinar hosted by ACR Journal. The webinar takes place on Thursday March 17 (2.30pm) and is the ideal platform to learn about R32 and get advice on the equipment needed and installation practices. It’s open to everyone, so don’t miss out on an opportunity to find out more about this up and coming refrigerant. Register here for free: www.r32webinar.co.uk

At last, the

INSTALLATION 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 James Richardson, Fujitsu’s technical engineer, looks at the actual installation.

he design of the building’s air conditioning system has been decided and a quote accepted- it is now time for the actual installation process to commence. Our theoretical two storey building (which we introduced in the previous columns), has a floor area of 160m2 per floor, with open plan and cellular offices and separate tenants per floor. For its efficiency and flexibility, we have selected a VRF heat recovery system, in this instance our VR-II has been selected. Before you start, you have to allow time for the installation engineers to become fully inducted onto the site, completing the necessary health and safety training. Liaising with the site manager well in advance ensures the process is completed in a timely manner. He, or she, will also need to know what will be delivered to site and when, and, at what stage other trades will have to get their part of the project up to before you can begin. With all of the above complete the installation can begin, but before any tools come out of the van, planning the job is vital for a smooth process. Things that need to be taking into account are: • Materials • Pipe runs • Condenser location • Indoor units location • Other trade services • Lifting equipment (if required) • Health and safety requirements Installation is usually broken down into two phases; first fix and second fix.

Fujitsu.indd 24

First Fix

The first fix is where we look to hang the indoor units and containment. All the indoors will be hung as close to the positions on drawings as possible. Our installation has large cassettes in the open plan areas with compact cassettes in the cellular offices. Nine times out of 10 slight changes have to be made due to various other services or a change of the drawings at the last minute.

Often with new builds such as this, the ceiling has yet to be installed so the cassettes will be hung and adjusted at the end to be level with the ceiling grid. As this theoretical installation is a heat recovery system, refrigerant branch boxes will also need to be installed in relation to the relevant indoor unit. A pipework schematic will be issued to help the installer lay out his pipework and install relevant separation tubes (see illustration).

LIAISING WITH THE SITE MANAGER WELL IN ADVANCE ENSURES THE PROCESS IS COMPLETED IN A TIMELY MANNER” 22/02/2016 12:33

Second Fix

Second fix is where we start getting towards the end of the installation and a lot of the hard work has been done. The final pieces that need completing are: • Final pipework connections completed • Communication cable pulled in and connected. • Drains installed • Levelling of indoor units • Grilles installed • Remote controllers installed Now that the installation is complete all the relevant information needs to be collated for the commissioning process, such as pressure testing and additional charge calculations. In the next column we will look at commissioning, always more of an issue than you may expect, but something that manufacturers can help you with.

A SIMPLE TOOL TO

REDUCE LEAKAGE S

chrader valves are commonly used on refrigeration & air conditioning because they are a simple, cost effective method of providing access to a system.

But they commonly leak. One cause of leakage is over or under tightening of the core. Most Schrader valve cores should be tightened to a torque of between 0.23 and 0.8 Nm.

Eliminating the guess work which results in over or under tightening will reduce refrigerant leakage. The photo shows an example of a simple torque tool. To use it simply tighten the core into the body until the tool clicks at its pre-set torque setting. The use of the torque tool also ensures that the Schrader core depressor is at the correct height, so it is not fouled or depressed when a cap is fitted, but is depressed only by the pin in the gauge line. Other ways of reducing leakage at Schrader valves include: ₀ Ensuring the correct core is used – one type does not suit all applications. You should select the core to suit the refrigerant, oil, pressure and temperature. Cores are colour coded and you should check compatibility against the manufacturer’s data sheets. ₀ Removing the core when brazing in the valve, and re fitting the core (using the torque tool) when the body has cooled to below 100C as a large number of cores are damaged before refrigerant is even introduced to the system.

Cool Concerns.indd 38

₀ Capping the valve with an appropriate cap (such as a hexagonal cap which can be carefully tightened using a spanner). The cap should be carefully selected for use with the particular Schrader core body. Access points in the system should be minimised. If possible do not fit Schrader valves, especially during installation for pressure testing where they are left in inaccessible areas such as roof voids and service ducts. Locations of access points, including Schrader valves, should be marked clearly on isometric drawings for future reference. For more information or to buy torque tools contact: hello@coolconcerns.co.uk Real Zero has more information about leak reduction: www.ior.org.uk/real-zero

A VALVE CORE comprises a machined component and a seal that screws into a separate valve body. The core seal is attached to a pin which is actuated when contacted by the depressor in your hose. An external seal on the core provides leak-free attachment between the core and body.

THE HEAT PUMP

EQUATION How Heat Pumps Can Help Commercial Buildings to Meet Building Regs and Planning Requirements

Commercial buildings must take an increasingly energy efficient approach if they are to meet the standards required by ever more stringent Building Regulations and planning requirements. Chris Stammers, from DImplex looks at how heat pumps can help a project to tick all the right boxes – and cut costs too.

“

THESE FACTORS ENSURE HEAT PUMPS ARE ALSO PERFECTLY PLACED TO HELP PROJECT MANAGERS TO MEET PLANNING AND SUSTAINABILITY REQUIREMENTS – WITHOUT HITTING THE BOTTOM LINE.”

It has been over two years since the 2013 revision to Part L of the Building Regulations came into force, a key milestone towards the government’s target for all new nondomestic buildings to be zero-carbon by 2019, and it has come as no surprise that the energy efficiency requirements of new buildings continue to rise. The 2013 revision of Building Regulations Part L2A (conservation of fuel and power in new buildings other than dwellings) demands a nine per cent improvement over the 2010 document, which itself set a 25 per cent improvement on 2006. And Building Regs are not the only driving force putting pressure on the sustainability of new projects; in many cases local planning requirements will demand even greater levels of efficiency. Specified improvements over Building Regulations such as BREEAM Excellent or the “Merton Rule”, which require new

DImplex.indd 40

commercial buildings over 1,000 sq m to generate at least ten per cent of their energy requirement using on-site renewable energy sources, are becoming more and more common. Heat pumps extract warmth from the air or the ground and compress it to provide highly efficient, economical heating. They are reliable, cost-effective and with additional income on offer from the Government’s non-domestic Renewable Heat Incentive (RHI), they can pay back sooner than you might think. In addition, the Building Regulations Approved L2A document now makes it mandatory to consider the economic feasibility of heat pumps - and give a good reason why they haven’t been selected. Together, these factors ensure heat pumps are also perfectly placed to help project managers to meet planning and sustainability requirements – without hitting the bottom line.

Simplified Building Energy Method (SBEM) – meeting targets

Building Regulations Part L is driven by CO2 emissions for the building, so low carbon solutions enable easier compliance and with lower achieved CO2 emissions than gas boilers, oil boilers and LPG boilers, heat pumps tick all the right boxes. For space heating, an air source heat pump with CoP (coefficient of performance) of 3.5 running with low temperature emitters such as Dimplex SmartRad fan convector radiators or underfloor heating will emit 0.13kg of carbon per useful kWh. Compare that with a brand new, A-rated gas boiler (0.21kg), oil boiler (0.32kg) or LPG boiler (0.29kg) and it is easy to see why heat pumps are reflected favourably in SBEM and BREEAM. What’s more, with a heat pump installation new buildings can meet their target Building Emission Rate (BER) with reduced installation costs, lower

running costs, simplicity of operation and reduced visual impact than an alternative system comprising of a boiler and Solar PV. Dimplex has launched a series of CPD programmes to support M&E contractors and project managers who are considering the benefits of heat pumps and there has never been a better time to go green.

BREEAM – earning credits

Heat pumps are well placed to meet the requirements of BREEAM too, the commonly-used, points-based assessment method for commercial buildings. BREEAM Excellent is now a requirement of all new Government buildings, Department of Health new build, DEFRA new build and some local authority buildings depending upon the local plan. For many more projects, it is a standard of excellence which is coveted but not unobtainable thanks to the continued

development of renewable technologies such as heat pumps. Simply considering heat pumps during the design process gains easy credits, which makes this technology a nobrainer for any project looking to prove its sustainability credentials.

Counting the cost

Of course, none of this would be relevant if heat pump technology was not costeffective. The biggest concern for many organisations looking to meet specified targets for carbon reduction is what impact it will have on the bottom line. With reduced installation costs, lower running costs and reduced visual impact compared with an alternative system compromising of a boiler and solar PV, there is plenty of benefits for those willing to go green. Financial incentives may also be available for commercial buildings through

the Government’s Non-Domestic Renewable Heat Incentive (RHI) scheme. Under the current tariff system commercial air source heat pumps can earn 2.5p/kWh over a period of 20 years which could mean additional income of £5,000 per year for larger premises (based on a 100kW commercial property with space heating demand of 200,000 kwh per year). Ground source heat pumps can currently earn a tariff of 7.2p/kWh, and so a similar property can expect to receive £14,400 per year over the 20 year period. All this, of course, on top of lower running costs compared to oil or LPG boilers. Inevitably, with continued innovation, improved efficiencies and higher tariffs comes lower payback periods. Now is the time to consider the heat pump equation.

HOTTING UP THE HEAT PUMP MARKET

Phil Hurley

The UK’s commitment to meeting binding EU carbon reduction targets translates to the practical challenge of installing 6.8 million domestic heat pumps by 2030. Phil Hurley, managing director at NIBE, looks at what the industry must do to take these numbers from projection to reality – including the pivotal role of the installer.

s an EU member state, the UK is obliged to reduce carbon emissions by 20% (compared to 1990 levels) by 2020 – and part of this means generating 12% of all heating from renewable sources.

These are big numbers, especially when you consider we’re currently only sourcing around 2% of our heating from renewables. If we’re serious about hitting these targets, the mass rollout of renewable heating technologies in homes across the country is the only way forward. Heat pumps have a fundamental part to play in this – and as a nation, we’ve recognised their potential by tasking ourselves to boost installations to 6.8 million by 2030. To put this into context, there are currently an estimated 110,000 heat pumps installed in UK buildings. There’s no denying that this is a huge step up. Even with the best intentions in place, it simply won’t happen without a clear strategy and the right support – both from the industry and from the government – to drive it forward. The good news is that the UK heat pump market has already

NIBE.indd 42

come on leaps and bounds in recent years, so we know continued success is achievable. But what are the steps that we, as an industry, need to take to push heat pump deployment to the next level?

Make the most of subsidies

To date, financial incentives such as the RHI have been a significant catalyst for heat pump uptake. Despite Chancellor George Osborne announcing plans to cut funding for the scheme by £700 million in his spending review last year, we mustn’t lose sight of the fact that the RHI remains an important ally in our quest to whet the nation’s appetite for renewable heat. Not only will the scheme continue until at least the end of this parliament in 2020, but the budget remains a substantial £1.15 billion – even taking the cutbacks into account. What’s more, although it’s not yet clear exactly what the new reforms will look like, or how they will affect heat pump tariffs, it’s almost certain that the technology will still be a prominent part of the RHI mix. It’s also highly unlikely that any planned changes will pass through parliament and be made official in time for the start of the new financial year in April. For this reason, at NIBE we expect to see the RHI continue in its current format for the entirety of the financial year 2016/2017 – which is positive for heat pumps as the current tariffs stand.

Spread the word

While government incentives have an important part to play in driving heat pump uptake, they’re not enough on their own to propel the technology into the mainstream. On a much broader – but arguably even more crucial – level, the industry has a responsibility to make sure potential customers know about the longterm financial, environmental and logistical benefits of investing in heat pumps. This is where installers takes centre stage. Often the first port of call for consumers looking for a new heating system, tradespeople are a trusted source of advice and expertise. This makes them naturally placed to lead the communication process – explaining the advantages of heat pump technology in layman’s terms and showing the quality, efficacy and breadth of systems available. Heat pumps are still a relatively unknown entity to many consumers (most of whom are far more familiar with traditional fossil fuel-based systems) – so they are very unlikely to be confident enough to invest without this reassurance and guidance. Reputable manufacturers should also be offering installers the right tools to showcase the benefits of heat pumps effectively. Accessible and appealing marketing collateral, such as product brochures and other sales aids, can go a long way towards helping homeowners understand exactly why renewable heat is the smart choice for the long term.

Build a strong workforce

As well as being in prime position to communicate with customers, installers also have the most important task of all: actually fitting the units in people’s homes. As with any technology, heat pumps must be correctly specified, designed, installed and maintained to ensure optimum performance and meet customer expectations. Poor installations invariably lead to poor results – which are ultimately damaging to the reputation of heat pumps and their capabilities. On the flipside, the best way to communicate what heat pumps can do is by showing a properly installed unit in action. With this in mind, investing time and money into developing and nurturing a wide-reaching workforce of highly skilled, highly motivated installers should be top of the agenda – both for manufacturers and for installers themselves. It all starts with proper training. As things stand, there are only around 1,200 MCS-accredited heat pump installers in the UK – which makes the 6.8 million installations target seem even more ambitious. While the onus is certainly on manufacturers to offer engaging training courses that entice more heating and plumbing engineers into the heat pump business, installers themselves should also be proactive about upskilling – especially given the significant

commercial benefits that are in it for them. That said, there is currently a great deal of red tape around MCS accreditation, which is understandably putting some installers off. That’s why at NIBE, we’re calling for the MCS process to be simplified and made more cost-effective. We believe this would make the heat pump opportunity even more attractive to installers – who will, in turn, make it attractive to their customers.

Drive legislative change

Last but not least, having the right legislation in place to support a steady upward trajectory of heat pump installations is vital. While short-term support from schemes like the RHI is a big help, we also need robust, long-term government policies in place – ones that are speciﬁcally designed to level

the playing field between heat pumps and traditional fossil fuel-based systems well into the future. It’s for this reason that NIBE has joined forces with other industry leaders to campaign for certain efficiency-enhancing measures to be made obligatory when gas boiler systems are installed in new-builds. For example, we want every new-build system to include a modulating heating control (like a weather compensator) in line with relevant ErP guidelines. If this were the case, systems would only use the exact amount of fuel they need to equal a building’s heat loss. What’s more, boilers can only operate at optimum efficiency if the system return temperature is below 55°C – so we are also asking for this to be set as a legal maximum. Changes like these would help lay the foundations for future heat pump installations by making today’s heating systems ‘low carbon technology-ready’. They would also have the knock-on effect of stripping away the market barriers that currently only unfairly challenge the low carbon heating industry, and not the gas boiler industry.

Bright future

When it comes to the national roll-out of domestic heat pumps, we’re already moving in the right direction. However, to ensure we meet 2020 targets and go on to achieve 6.8 million installations by 2030, we must not lose momentum at this crucial point in time. Installers, manufacturers and other industry stakeholders need to join forces and spread the message that heat pumps should be at the very heart of our vision for an energy-secure UK. www.nibe.co.uk

WHAT’S NEW

Hitachi Releases Lowest Noise Level Mini Cassette

New Condair Electrode Steam Humidiﬁer

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.

Condair is launching a newly developed electrode boiler steam humidifier that has longer lasting steam cylinders to reduce humidification maintenance requirements and operating costs. The Condair EL also incorporates the latest touch screen control technology, has BMS integration as standard and a high output of up to 90kg/h from a single unit. This new humidifier is an economic yet reliable solution for either in-duct or direct air steam humidification. It is easy to install and operate with a straightforward service requirement of replaceable steam cylinders. The Condair EL range includes models with maximum outputs of five to 90kg/h from a single unit with outputs of up to 180kg/h possible through master/slave configurations.

HELPS CHILDREN’S HOSPICE WITH AC SYSTEM

TF Solutions, the AC distributor, working with Fujitsu Air Conditioning and Lawton Tubes, recently helped out a Staffordshire children’s hospice with £30,000 of VRF air conditioning equipment. The companies donated the equipment to the The Donna Louise Children’s Hospice which helps children with ‘life limiting conditions’ throughout Staffordshire and Cheshire. TF Solutions has a long relationship with the charity, the company’s nominated charity. Since starting to work with hte hospice, TF Solutions has already raised over £10,000 through its fundraising efforts. TF Solutions designed, planned and installed the complete project for free. The project took several weeks to complete to install the new energy efficient, environmentally-freidnly system.
