I recently read a report about the distinct possibility that energy could be free in the near future. The free energy would come as a result of technology in development which uses renewable energy sources.

Some of the technology includes solar panels which are sprayed onto glass. Using renewable energy would mean that we use far more solar energy than we now do. And, with the cost of systems which convert the solar energy into electricity dropping in price quickly, it would be more affordable for everyone.

Just imagine what that would do for cooling industry – free energy!

But, is it free? The big challenge, of course, is storing all that ‘free energy’.

Battery technology is not very good, in reality. And, you still need to spend money on the renewable energy systems.

However, when battery technology improves (it’s not far off, I understand), it could revolutionise parts of our industry.

Until then, energy efficiency is still one of the most important topics for all of us.

CIBSE Publishes Guide B on HVAC Hargreaves Supplies Ductwork Solution to Chernobyl Nuclear Plant The Chartered Institution of Building Services Engineers (CIBSE) has published new guidance on heating, ventilation, air conditioning and refrigeration in the latest edition of their ‘Guide B’.

The new edition is is bigger and includes revisions on noise and vibration control, and new legislation. There is a new chapter, B0, which covers designing different building functions. The chapter is ideal for new engineers, or more experienced engineers new to the topic.

The CIBSE Guide B was last updated in 2005 and is one of the organisation’s main publications. The guide provides practical help for designing HVAC systems.

Chair of the Guide B Steering Committee, Roger Hitchin said: “We are delighted to be able to release this comprehensive update to Guide B, which has required years of stringent work as one of CIBSE’s most important guides to one of its core areas of expertise.

“The inclusion of Part 0 to the new Guide has been driven by changes we have seen in the industry, which has seen more and more engineers join building services from other disciplines or more general engineering degrees.

The intention is to make this transition easier and to make their future work more effective by helping them to understand the issues created by different contexts, and their relevance to HVAC design.”

Buy the new guide in print or digital format (Part B0 is a free, digital-only download) online here: www.cibse.org/ knowledge/cibse-guide

UK HVAC company, Hargreaves, has won a contract to supply 6,000 metres of ‘high integrity ductwork’ to Chernobyl nuclear site in the Ukraine. The Chernobyl site is one of the biggest engineering projects in the world at the moment.

Hargreaves won the multi-million pound contract with Novarka, and it is the only British contractor on the innovative project, the so-called Chernobyl New Safe Confinement (NSC).

The Hargreaves contract means the company will have to deliver a bespoke ventilation and containment solution for the NSC. The project includes consultancy, design, manufacturing, engineering and procurement.

The project has a 108-metre high arch which will prevent radioactive materials from being released from the nuclear reactor for, at least 100 years. The Hargreaves project will mean they need to supply 36 HEPA filters, 77 fans and 38 air handling units, and instrumentation.

It is a massive HVAC project. There will be more than 2,000 people from 21 different nationalities working on the project. Thankfully, there will be 60 radiation experts on site to keep everyone safe. The money for the whole project comes from European Bank for Reconstruction and Development (ERBD), plus other contributors to the €2.5 billion.

BREXIT:

Business As Usual for A-Gas

A-Gas managing director, John Ormerod, provides his opinion on the outcome of the EU Referendum result and how it will impact the UK air conditioning and refrigeration industry.

He said: “The outcome of the referendum has ushered in a significant period of uncertainty for the HVAC industry and the broader economy. The exact terms of Britain’s exit from the EU have still to be determined and are likely to take several years to complete. In the interim, it will be business as usual for A-Gas. The result has however, raised a number of questions from customers seeking clarity on some key issues.”

How does this affect the F-Gas regulation?

“The F-Gas regulation has been adopted into UK law and therefore the provisions in it will still apply to the UK even after Brexit.”

What about exchange rates?

“We have already seen significant volatility in both the £/€ and £/$ exchange rates. This is likely to have an effect on the volatility of refrigerant prices as the cost of production is based on these currencies.”

Will Brexit affect refrigerant availability?

“We do not foresee specific problems in the supply chain arising from the referendum outcome. Our supply chain is protected by supply contracts and our own sources of reclaimed refrigerant place us in a good position to continue to meet our clients’ requirements.”

Adande Opens New Test Facility

Adande, the Lowestoft-based innovators in refrigeration solutions, opened its new research and testing facility last week.

Liz Truss, the Conservative MP and, at the time, Secretary of State for Environment, Food and Rural Affairs officially opened the facility at Barley Way in the Suffolk town.

She stated: “The British food and drink industry is leading global innovation right across the food chain. The energy saving technology on show today and Adande’s investment in research and development are fantastic examples of how the sector can become more competitive through reducing its environmental impact. Not only will this technology help to reduce energy consumption and cut costs, it will keep food at its best for longer and help reduce food waste.”

Adande has invested £4.2 million into the business recently, £500,000 of which was used to design and build the new laboratory. With its partners, Adande intends to boost the development of its unique retail refrigeration solution, Aircell, and bring it to market.

Aircell, is a patented air flow management system which reduces the amount of energy needed in refrigerated display cabinets used by supermarkets for groceries. The investment will speed up Adande’s development program for Aircell so they can supply more retail customers in the UK and abroad.

BUILDING SERVICES:

Big Companies Should Help Small Companies In his inaugural speech as President of the Building Engineering Services Association (the BESA), Malcolm Thomson has encouraged the organisation’s larger members to select smaller members as preferred suppliers.

At the BESA annual general meeting, recently, Thomson stated: “We must emphasise to clients the high levels of technical competence, commercial capability and adherence to safety best practice that members are required to maintain – and we must address the skills shortages that threaten to limit the extent to which members can take advantage of commercial opportunities.”

He continued to say that it was vital for the BESA members to ‘protect and enhance’ the reputation of the association’s members for quality and reliability. Thomson emphasised his wish, during his presidency, to encourage ‘major members to use its smaller members as preferred sub-contractors’.

Smaller companies join the BESA to understand the best practices of the bigger members. In turn, they learn to be more professional, to innovate and be more efficient.

Malcolm Thomson believes that better relationships between large and small members of the BESA will be mutually beneficial.

CRYOHUB TECHNOLOGY – A STEP CHANGE IN ENERGY SAVING FOR FOOD COLD STORES AND FOOD PROCESSING FACTORIES

F

or designers, owners and operators refrigerated food cold stores and food processing plant; energy is big business. In an attempt to look at how the food processing and chilling industry use energy in a new way a team of engineers and researchers under the title of CryoHub are looking at using energy storage techniques which allow power to be supplied back into the grid as well as providing cooling for cold stores and food factories.

What is CryoHub?

CryoHub uses the fact that an industrial refrigeration plant has a significant demand for electricity to produce cooling, and that sites in areas that are highly suited to renewable energy generation. However renewable energy production tends to be intermittent, and the site needs a continuous and reliable supply.

By employing renewable energy sources first to liquefy and then store cryogens, CryoHub can overcome this. “The potential

10_IOR.indd 10

is enormous,” says project leader Judith Evans of London South Bank University. “Not only can this help to balance the power grid, but it is also ideally suited to using waste heat from equipment and components in refrigerated food warehouses – everybody wins!”.

With the UK gearing up to the challenging target of 20% of its energy demand satisfied by renewal energy sources by 2020 it means that renewables are going to become increasingly widely available in the next few years. Also, demand from the food cold chain for energy is increasing as the market for refrigeration expands.

Cryohub will help match these two key trends. The Cryohub technology could allow food producers a readymade package to integrate on-site management of heating, cooling, energy storage and waste generation.

The big benefit here is that they will be able to sell any excess energy back to the grid at peak demand times!

Become a CryoHhub Champion now

If you think there could be an opportunity for your business, whether you are a cold store/factory owner, consultant or designer/installer, please get in touch with the CryoHub group to see if you would be suitable to become a CryoHub Champion Site. We are currently looking for a small number of sites that will benefit from EU funding for installation and equipment.

The sites will also benefit from the expertise of the CryoHhub team who will carry out in-depth monitoring to ensure that sites achieve savings and supply/demand is balanced. As a part of the CryoHub, it is an opportunity to boost your company’s sustainability credentials as an environmental pioneer and test out cutting-edge technologies for energy saving.

Matching renewable energy supply and demand

A map of both UK and EU, which overlays cooling demand against potential renewable energy supply sites, is being developed. The map will help owners of refrigerated cold stores and food processing facilities to plan for how they could integrate renewable sources into their energy mix in the future.

If you own or operate a food processing site using greater than 0.5 MW of electricity for refrigeration (on average), please get in touch via our Survey at www.surveymonkey.co.uk/r/cryohub so we can add you to the cooling demand map.

Find out more about this exciting opportunity at www.cryohub.eu or contact Judith Evans at London South Bank University (j.a.evans@lsbu.ac.uk).

HPA POSITIVE ABOUT

DEMISE OF DECC

New Business, Energy and Industrial Strategy Department a welcome nod to joined-up government, says Nankivell.

C

ommenting on Theresa May’s new cabinet, Mike Nankivell, President of the Heat Pump Association (HPA) said:

“Few could have predicted the political upheaval that resulted from the BREXIT vote, or that we would now have a new Prime Minister and a radically restructured cabinet.

The HPA is pleased to congratulate Theresa May on her appointment as Prime Minister. Mrs May is the HPA’s local MP, as her constituency includes Hare Hatch near Reading, where we are based.

She has always been very receptive to our communications and appeared to

support strong action on climate change.

In 2014, she readily agreed to be the keynote speaker at the 30th Anniversary of the Federation of Environmental Trade Associations (FETA), under whose umbrella the HPA operates.

The HPA has always worked closely with government departments - in particular, the Department of Energy and Climate Change (DECC) - and we were initially somewhat alarmed at the news reports that DECC would be amalgamated with another government department.

We have had occasion to be concerned in the past that critical synergies on

environmental matters could not be effectively achieved because of communication difficulties between the separate departments such as DECC, DCLG, DEFRA and BIS. We believe that the new Business, Energy and Industrial Strategy Department could, in fact, be an extremely positive and welcome step towards greater joined up thinking on stimulating the take up of heat pumps, renewable heating and carbon reduction.

Refrigeration system energy consumption typically accounts for 50-70% of an operators running costs. Through good practice and taking advantage of available technology, operating costs associated with refrigeration can be reduced through: ₀ Retailer operation ₀ Service and maintenance ₀ Store Refitting ₀ Replacement Daily operation

An operator can improve efficiency by ensuring good disciplines are followed: ₀ Optimising air flows through eliminating obstructions, e.g. ensuring products do not cover display case air return grilles. ₀ Ensure a manufacturer’s maximum fill line isn’t compromised as over loading a display case will restrict air flow. ₀ Switching lights off when there is no requirement to illuminate product. ₀ Keeping cold room doors closed. ₀ Ensuring night blinds are used correctly.

Service and maintenance

Alan Jackson, BJA Refrigeration Consultants

Maintenance can play a significant role in improving efficiency during routine maintenance visits. Examples include: ₀ Ensure evaporation set points are maintained at the manufacturer’s recommended conditions. ₀ Optimise and maintain compressor set points by ensuring the suction pressure is only as low as it needs to be and that the discharge pressure is set as low as possible. ₀ Ensure that condensers are clean and have free air flow to them. Blocked condenser fins will result in higher condensing temperatures, and for each 1°C the power used by the compressor will increase by c. 2-4%.

ENERGY EFFICIENCY

By Alan Jackson and Stewart Bonner from BJA Refrigeration Consultants

BJA.indd 16

₀ Perform system leak checks; alongside the environmental impact, leaking refrigeration systems can also increase energy consumption.

Store Refitting

Refitting presents a significant opportunity to improve efficiency. The following examples of investment are worth considering: ₀ Installing doors to display cases will significantly reduce energy consumption and load. A new initiative that will reduce energy consumption to open fronted display cases is to install them with Aerofoil Energy technology. Aerofoils are patented shaped strips that are fixed to the ends of display case shelves and positioned to sit in the outer edge of the air curtain. Aerofoils reduce energy costs and air curtain spillage through improving the direction of air flow.

N.B. If the cooling load is reduced on an existing refrigeration system, care and consideration must be given to the effects the load reduction might have on the system reliability: • A reduced load means the plant may now be too large and cause shortcycling of the compressors • Reduced load also means reduced mass flow in the piped services and this could cause problems with oil return ₀ Replace traditional lighting fixtures in display cases and cold rooms with LED lights. ₀ Replace thermostatic expansion valves with electronic expansion valves. ₀ Maintain air tightness and thermal integrity by repairing any fabric leaks in cold rooms. ₀ Replace condenser fan motors with EC fan technology. ₀ Installation of inverter control technology to compressor packs will

alternatively can be used to support a store’s hot water requirements. ₀ Installing a condenser with a sub-cooling circuit will ensure that the refrigerant is colder than the saturation temperature; increasing the quality of refrigerant at the expansion device. ₀ Install display cases that utilise doors or Aerofoils and LED lighting. ₀ Remember that what you cannot measure you cannot control. Installing a high quality control and monitoring system assists you to do both.

optimise compressor operation through ensuring that staging is ‘smooth’ as the system load demand changes. This will minimise compressor starts and reduce energy consumption. ₀ Investing in condenser fin corrosion protection extends the life of a condenser whilst also presenting energy savings. ₀ Replacing pipework insulation that is damaged or has broken down over time will prevent unnecessary heat gain.

Replacement

Equipment replacement present a significant opportunity to improve efficiency. The following examples of investment are worth considering: ₀ Replace multi-condensing unit systems with centralised plant. Alongside efficiency benefits the number of brazed connections will also reduce that over time will minimise leakage potential. ₀ Select refrigeration plant that has the potential for heat recovery. This can be used to supplement a store’s heating requirements as low grade heat, or

Summary

This article identifies steps that can be made to improve energy efficiency, whether through daily operation, service and maintenance, retrofitting or replacement. The suggestions connected with retrofitting and replacement have a varying capital cost, however when considered against the life cycle of a systems operation, these improvements will provide a return on investment through reduced energy consumption.

KEY ROLE FOR J & E HALL CONDENSING UNITS AT BAKERY

Six J & E Hall Fusion commercial condensing units are playing a key role at a Cumbrian bakery, which suffered a devastating fire last year.

C

arlisle-based Lakeland Bake was destroyed in a blaze last May and once the dust had settled, it was decided to rebuild the business from scratch and move into larger premises.

Lakeland Bake had built up a good reputation supplying crumpets to national supermarket chains and other retail outlets over the years. As well as a range of classic nutritious crumpets – characterised by their light and crispy texture – they also pioneered popular Christmas tree-shaped crumpets supplied to Asda.

The J & E Hall equipment was chosen for the two yeast chiller rooms and the vitally important area where crumpets have to be carefully cooled, under controlled conditions, to ensure optimum quality prior to packing.

The installation work was carried out over a two-month period by Carlisle

JE Hall Bakery.indd 20

Refrigeration led by senior engineer, Tom Atkinson. Carlisle Refrigeration service and contracts manager Paul Ferguson said: “It was an empty unit so we effectively had a blank canvas to work with.”

For each of the two yeast coldrooms a JEHR-0140-B2 M-1 Fusion medium condensing unit was chosen to work in tandem with a Searle KEC25-4L evaporator.

Keeping the Crumpets Cool

In the crumpet cooling area, four J & E Hall JEH2-1000-M-3 Fusion twin-fan condensing units were teamed with Searle DSR 1000-3 dual discharge evaporators. “There were no issues with the job, everything went according to plan,” said Paul. The units were supplied

by FSW of Preston.

J & E Hall Fusion units offer the perfect solution for commercial refrigeration sectors. Energy efficiency is key to product

design and the fully factory-built units are quiet and easy to install. A future-proof design process, evolved over a number of years, ensures the units comply with all relevant European standards and the latest legislation. Fusion units can be used with confidence in applications including cold stores, convenience stores and petrol forecourts.

“As far as J & E Hall units are concerned, we have always found them to be very reliable,” said Paul. “They are very easy to work on and components are easy to access. Parts are readily available off the shelf should they ever be needed.”

Carlisle Refrigeration was founded in 1973 and also operates out of Glasgow and Gateshead. Paul said that the business was delighted to help Lakeland Bake build a brighter future after a traumatic few months. “It feels good. We had worked with them prior to the fire. We are very proud of the whole installation.

It has been completed to a very high standard,” he said.

Director of Lakeland Bake, Nigel McKerr said: “Carlisle Refrigeration has an

excellent reputation. Their service cover is second to none and they are experts at what they do. They are on the neighbouring industrial estate so they are readily available.”

Controlled Crumpet Cooling

Controlled cooling is a key part of the crumpet production process, as Nigel explained: “Too fast would be aggressive and damaging to the product. Like any baked item, if you blast it, it can have a detrimental impact on the eating quality. What we sought to do with Carlisle Refrigeration is put in place a solution which isn’t just on or off but gives us an infinite degree of control.

We have bought very energy-efficient equipment. It’s early days but the proof of the pudding will be in the long-term running.

First impressions are very good.”

The new premises are double the size but the major challenge ahead will be in

winning back trade lost while the business was out of action.

Nigel added: “May 9th last year was a dark day when we lost our bakery of 10 years standing, but we decided to rebuild.

We have a faith in the quality of our products which is undiminished and I think we have something different to offer the market. We have taken the opportunity to develop some new and improved recipes and we shall be launching some exciting new products.”

PEOPLE NEED

MAINTENANCE TOO! W

hy is it that we can plan and implement effective Planned Preventative Maintenance (PPM) for RACHP equipment and systems, but we seem to struggle with the concept that ‘People Need Maintenance Too?’

Integral’s Industrial Refrigeration Director, Dave Bostock, explains the impact that developing their employees has on their business.

Our most valuable asset, our people, often receive the least proactive (planned, preventative) attention!

I say proactive on purpose, because most RACHP companies have lots of processes and procedures to manage reactive (breakdown) situations when something goes wrong with our people.

A lack of maintenance, whether it is people or equipment will inevitably lead to more breakdowns. It delays the inevitable.

Good service begins with good people

At Integral Refrigeration we believe that people need maintenance too.

Whether you are a contractor and service provider, or a product developer and manufacturer; it all starts with people.

Without good people we cannot develop good products and make them to a high quality. As a contractor/service provider, where you really only have people as your product; unsurprisingly, you cannot provide a good service without good people.

PPM with people is really just investing in their training and development to ensure smooth, efficient, reliable running following an agreed plan. This is Planned, Preventative (Proactive) and Maintaining (Retaining) them.

One service company I know had a rule-of-thumb that equated the cost of replacing a lost field service engineer to one full year’s revenue (revenue and not just salary).

Integral.indd 23

refrigeration

If we can persuade a customer that PPM has long-term financial benefits so it is worth the investment, we should also believe the same is true for our people.

Do it better

At Integral Refrigeration we aim to recruit, train and develop staff primarily based on the right attitude; those who want to learn and grow. We can teach them all the technical information they need or want to know then guide their real world experiences to add practice to the theory.

These behavioural skills are finally being recognised as not only important, but essential to the development of good people. These are the people who can, and want to, grow with us and our customers.

Dave Bostock

As a leading RACHP organisation we want to be constantly challenging ourselves, our suppliers and our customers to do it better. This is a mission, not just a job.

As a truly independent solution provider, at Integral we are free to choose the optimum system designs and equipment selections to achieve the best result across all capacities and applications. We can choose from all manufacturers and product ranges. This is a powerful advantage for our customers, also a great opportunity for our staff to learn and experience a complete range of refrigerants and technologies.

Developing young people

I spend a lot of time involved with various trade associations and institutes discussing training and development within the RACHP industry and it is quite common for the primary concern to be attracting new, young, bright people.

In recent discussions about new Engineering Technician Trailblazer Apprenticeships, I have discovered that very few apprentices were taken through to Level 3. I was told that ‘we will not be able to retain them, keep them satisfied, or meet their ambitions’. I was a little surprised at this.

10/08/2016 12:30:20

24 SEPTEMBER 2016

To keep customers happy and engaged with us as their provider we need to show not only good service, but continuous improvement. Of course this needs continuous improvement in our own thinking and perhaps being challenged a bit by our juniors!

The strength of our industry lies in the grass roots, customer-facing elements.

This is the area, in my opinion, that we need to further develop as a priority and then implement continuous improvement in the form of professional development.

Shaping the RACHP industry

That is why at Integral we play a proactive role in industry trade associations, Institutions and work groups, and we are currently active as stakeholders in the Engineering Technician and new Higher Level Apprenticeship for Design and Applications Engineers Trailblazer Apprentice Schemes. We also have staff members active in the BESA, BIFM, BRA, ACRIB and IOR to name just a few of the industry bodies we engage with.

We want help shape our industry, not just follow. We share the passion and commitment to raising standards and continuous improvement.

“

In my perfect world everyone who touches or has an influence over the specification, design, installation, commissioning, maintenance and service of RACHP equipment should be a professional. In our industry one definition or measure of professional competence can be registration with the Engineering Council. This measure also embodies the principle of continuous improvement through Continuous Professional Development (CPD).

The learning and the growing should never stop. Job satisfaction and staff retention have been linked to realistic and practical learning and development opportunities. Stretching ourselves just a little on a regular basis keeps us fresh and engaged. CPD is just a structured (Planned) method to ensure that people get sufficient attention (Maintenance), and this ‘People PPM’ provides continuous payback in retaining a company’s investment.

Get involved

At Integral Refrigeration we encourage and support our people to apply for Engineering Council registration so that we, and this really means them personally, and our customers, can recognise their

competence and professionalism – and take pride in it.

Why would bright young people want to join our industry, and what career path can we offer them? Can we show and inspire them to forge a route from apprenticeship to being a senior Director of a £500m business with challenging, rewarding and ultimately satisfying roles all along the way?

We see Integral Refrigeration as a team of professionals with innovative solutions to help you stand out and advance your career.

Personally, I have been on a more than 30 year fantastic journey in our industry along just such a route and, at Integral, I believe I have found a place where anyone with the right attitude and determination will find guidance, encouragement, investment, support and opportunities to blaze their own trail to job satisfaction and professional fulfilment.

Every journey starts with a single step, so if you are looking for something more, then contact us and we can search together. At Integral we want to put passion and professional pride back alongside procedures and enjoy the journey: refrigeration@integral.co.uk

RETROFITTING R404A A-Gas Managing Director John Ormerod with ten top tips on how to maintain best practice when replacing R404A with a lower GWP refrigerant Why is it important to make the switch from R404A to a lower GWP refrigerant?

This is the time to focus on replacements for R404A, one of the most widely used refrigerants in the industry. The F-Gas quota system is making an impact as the push towards reducing the amount of high GWP refrigerant in use gathers pace.

R404A, with a GWP of just under 4000, will be one of the hardest hit by the changes and everyone agrees that if business continues as usual, by 2018 there won’t be enough of this refrigerant to go around to meet the needs of the industry.

How do you decide on which refrigerant to choose for the retrofit?

It must have similar operating characteristics to R404A in terms of being a medium or low temperature replacement. To achieve this you must match the refrigeration capacity as closely as possible with the lowest GWP refrigerant that is available. The industry should banish the word dropin because there really is no such thing.

With the introduction of any replacement refrigerant an adjustment will have to be made to the system to get the best out of it; it is not a case of simply dropping it in.

AGAS.indd 26

What is the easy way to record the amount of refrigerant recovered?

It is a key aspect of the retrofit to discover what the system has been running on beforehand. It is also important to record the quantity of refrigerant put in or taken out of the system to satisfy the obligations of the F-Gas Regulations.

Online reporting tools like Gas-Trak Online™ (GTO) from A-Gas make this easy. They allow engineers to cut down on paper use by producing electronic F-Gas log books and reports.

John Ormerod

Which retrofit refrigerants spring to mind?

Your refrigerant supplier will be able to help you in the selection of the most appropriate refrigerant for the system. You should consult with the equipment manufacturer too before making a final decision.

There are several suitable retrofit refrigerants on the market – R407F is a medium GWP option but Opteon XP40 (R449A) and Solstice N40 (R448A) offer a lower GWP alternative. They are currently the lowest GWP replacements on the market (around 1400) and are closely matched to R404A in terms of refrigeration capacity.

How should you dispose of the old oil from the compressor?

An oil change is a vital part of a refrigerant retrofit. Getting rid of waste oil, especially small quantities, has traditionally been a problem for engineers. Remember that this old oil can contain refrigerant and safe storage and responsible disposal is key. A-Gas offers an oil disposal service through its wholesale partners to take care of recovered oil. Each container has a venting cap to ensure any refrigerant absorbed in the oil does not cause the waste container to expand. This is a safe and environmentally friendly way of dealing with what has been in the past a tricky problem.

How does the choice of refrigerant affect the charge size?

To avoid any issues with a retrofit, first measure the operating conditions.

This includes discharge, suction pressures, suction line temperature, compressor amps and super heat before using the liquid sight glass as a guide.

Follow the refrigerant manufacturer’s recommendation regarding initial charge size before making adjustments to the system. Use dew point pressure as a reference in determining the appropriate temperature for a superheat setting. To determine the saturated temperature for a sub-cooling calculation use bubble point pressure.

Why is leak testing so important?

Leak detection is a key part of ensuring that the F-Gas Regulations do achieve what is expected of them; if a system doesn’t leak, it won’t require topping up, and this in turn helps the industry meet the phase-down under F-Gas. A retrofit, with the gas out of the system, is a great opportunity to raise the bar on this. Making sure a system doesn’t leak has never been more essential and this will clearly save the customer money in the long run.

The route to success is to follow best practice, so relying on pressure or vacuum decay – or using bubble spray – won’t be enough. Technologies like Trace-A-Gas® from A-Gas can provide a high tech and economical solution. Using a suitable detector, this method is 100 times more sensitive than bubble spray.

Leaks can be detected in the smallest quantities and very quickly.

AGAS.indd 27

How should you monitor the system performance?

This is a crucial part of a retrofit and you should start monitoring while the system is still running on R404A by recording the typical running conditions. All the standard system operating parameters should be checked to establish the benchmark temperatures and pressures.

Why is labelling so important?

The F-Gas Regulations have changed the labelling requirements. Not only must you now record the amount of refrigerant in the system but you should now record what the GWP is and its CO2 equivalent value. GTO has a handy calculator which

can make this a quick and easy task. As the regulations march on it is likely that we are going to have many different types of refrigerants used, so labelling has never been more relevant. It is also important for engineers to know exactly what’s in a system. Generic F-Gas refrigerant tape is now available to allow systems to be labelled accordingly with all of the required information.

How important is it to dispose of the old refrigerant correctly?

This is a legal obligation because it is classed as hazardous waste. Under the F-Gas phase down it is crucial that as much old refrigerant as possible is recovered, reprocessed and made available to the market. The phase down is a steep curve and leading industry organisations are pointing to the fact that reclaimed refrigerant is going to play a major part in keeping the supply chain moving beyond 2018. www.agas.com

Top Ten Tips for Maintaining Retrofit Best Practice: Look at all lower GWP refrigerant options Decide which retrofit refrigerant to use Switch to a lower GWP refrigerant Record the recovered refrigerant Dispose of recovered oil responsibly Consider the charge size Leak test the system Monitor system performance Label the system correctly Dispose of recovered refrigerant responsibly

CLOSING THE NET ON

THE BLACK MARKET Dr Stuart Corr, techno-commercial director of Mexichem’s Fluor Business Group, discusses the details and what the industry can do to combat this.

I

t is fair to say that historically, highly regulated products make the trading of goods “under the radar” a more attractive option for operators at the fringes of the market. As the F-Gas Regulations quota system will increasingly restrict the supply of higher GWP HFC refrigerants, it’s possible that such a “black market” trade may increase.

As the large 2018 reduction in F-Gas quota availability draws closer, industry attention is focussing on how the move away from widely used, higher GWP HFC refrigerants such R-404A can be managed. Given the slow speed of this move to date, it is possible that we will face a situation where demand for the likes of R-404A begins to outstrip the volume that suppliers are permitted to place on the market.

This may lead some in the market to seek alternative options in securing these HFCs which can lead to a number of problems. In some cases,

Mexichem.indd 28

HFCs can be deliberately or unwittingly mixed with lower quality, counterfeit or illegally imported HFCs. With few checks and controls in place, such HFCs could result in reliability or performance problems with little or no comeback on the supplier – in effect, those operating in such a fashion take their chances.

By nature, black markets can have the effect of distorting economic data because transactions are undocumented.

As a result, it is almost impossible to give a true estimate of the amount of illegal HFC imports in Europe. Unregulated importers, trading outside of the F-Gas quota, have no responsibility to report to the European Commission, making this underground trade even harder to police.

Action on Refrigerant Black Market

There are several actions the industry as a whole can take to ensure black market trading does not increase.

First, buy from a reputable supplier who is happy to confirm their entitlement to quota. Secondly, those currently using higher GWP HFCs such as R-404A should seek alternatives as soon as possible.

Lower GWP HFC options such as R-407A offer an effective short to medium term solution given their reduced environmental impact and relative ease to retrofit which has been repeatedly proven in use.

The industry must also continue to discuss how to best monitor and control HFCs to close the net on black market suppliers – helping the authorities by reporting any instances of suspected illegally imported products is an important step in doing this.

The facility is a hub of technology and research excellence in the development of second generation biofuels produced from wastes and non-food crops, and features seven laboratories. This impressive facility required a range of rooftop services which needed support, including chillers, air handling units, fans and ducts and a large elevated louver screen.

Roof Support Solution

Because the roof was constructed using a delicate single ply membrane, a support solution was needed that would not damage it. The contractor on the project, therefore, specified Big Foot’s nonpenetrative supports as the ideal solution, selecting a broad range of products to support these services.

Following on from the initial work, Big Foot Systems was then approached to assist in the re-installation of the surrounding rooftop louver screen to meet both acoustic and aesthetic demands set by the local Planning Authority. As space around the periphery of the roof was exceptionally tight and penetrating the roof or parapet wall was unacceptable, a bespoke non-penetrative solution was required.

Big Foot Systems worked closely with the contractor to design the support solution. The result was four different methods of support, dependant on location, some of which cantilevered off existing Big Foot Systems products supporting other plant.

Education: Where did you study and what course, diploma or degree did you gain?

B.S. Mechanical Engineering – University of California at Berkeley M.S. and Ph.D. Mechanical Engineering – Georgia Institute of Technology

A D R I E N N E

This month, the ACR Journal interviewed Dr Adrienne Little, Fellow at the Advanced Research Projects Agency – Energy (part of the U.S. Department of Energy) about her career and insights into the diverse world of cooling and heating.

Thermodynamics would set me up well to work on a variety of energy systems.

As it turns out, I was right.

While my Ph.D. focused on the development of ejector waste heat recovery systems to produce cooling, I also had the chance to explore other thermal system areas related to data center cooling, dynamic modeling of supercritical CO2 bottoming cycles for power plants, and concentrated solar thermal power generation, to name a few.

Who do you work for and where do you work?

The Advanced Research Projects Agency – Energy (ARPA-E) advances high-potential, high-impact energy technologies that are too early for private-sector investment. ARPA-E projects have the potential to radically improve U.S. economic prosperity, national security, and environmental well being.

We focus on transformational energy projects that can be meaningfully advanced with a small investment over a defined period of time. ARPA-E empowers America’s energy researchers with funding, technical assistance, and market readiness. ARPA-E Program Directors and Fellows serve for limited terms to ensure a constant infusion of fresh thinking and new perspectives.

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

http://arpa-e.energy.gov/

What attracted you to the industry?

My professional aspirations have always been driven by a desire to make the most difference in the world. Early in my undergraduate education, I identified the need for clean and ubiquitous energy sources to be one of the most challenging problems, and a core issue linked to many problems we see related to poverty, environment, equality, and technological development.

L I T T L E

In order to best position myself to make an impact in the energy industry, I chose to study Heat Transfer and Thermodynamics in graduate school and joined the Sustainable Thermal Systems Laboratory under the direction of Dr. Srinivas Garimella. Because nearly all power generation and energy utilization goes through some sort of thermal pathway, or at least has a thermal consideration, I thought a strong background in Heat Transfer and

My current position as a Fellow at ARPA-E is unique. While I do use my expertise in thermal systems to evaluate funding proposals in the area, the spirit of ARPA-E encourages me to expand outside my area of expertise. As such, I have been developing my knowledge base in multiple areas that can be interpreted as orthogonal to Heat Transfer and Thermodynamics, but in many ways complementary.

Since many forms of innovation seem to occur at the interface between two technical areas that have traditionally been kept apart, I have targeted interesting combinations of different fields with Heat Transfer and Thermodynamics. Some candidate fields I have identified are Manufacturing, Materials, and Active Matter Physics.

As a Fellow at ARPA-E, I am looking for new materials and manufacturing methods, as well as radically different working fluids that can aid in expanding the existing thermal

system engineering toolbox. For example, this can range from additively manufacturing heat exchangers out of materials that allow anisotropic conductivity, or using newly developed active fluids to eliminate the need for fluid pumps.

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

There are very good reasons why things are done the way they are in industry today.

Typically, systems are designed and constructed to reduce cost and to have easily manageable product lines.

Especially during my time at ARPA-E, I have been gradually exposed to different examples of this way of thinking. One cannot simply make a great technology and expect that its technical merits alone will ensure its widespread use.

One must understand how that technology will interface with existing product lines, manufacturing facilities, and markets in order to make a notable impact.

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

I am excited by the fact that there are so many opportunities for innovation.

In many ways, the heat exchangers we use today look very similar to the ones we used a century ago. The set of components we get to choose from to design a heat pump have stayed fundamentally the same.

With new advances in manufacturing, biostructuring of materials, and active fluids, we can potentially bring about extraordinary changes in thermal systems the way we have seen extraordinary changes in other technical areas.

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

Think outside the air conditioning unit box. Especially as a younger engineer entering the workplace, position yourself to make higher-level impacts that can

Women in ACR.indd 33

fundamentally change how people think.

How can we eliminate the compressor of a vapor compression unit? How can we tailor the properties of a refrigerant in real time to match environmental conditions? How can we modularize a heat pump to make it smaller, cheaper, and useful for a wide range of applications?

Consider alternate applications. How can you use your skills to help people more effectively? Can you make a lowcost AC unit to harvest water in humid environments where electricity might not be available? Can you imagine a mini cooler that could ship vaccines more effectively? Can you design clothing that would eliminate the need for air conditioning in buildings?

In the end, the most effective people are those who have a wide network, especially outside of their area of expertise. This is because with multiple ideas and more information inside of your head, you can make more interesting and creative connections than other people can. That is the key to innovation. So be curious, ask people questions about their own background, and leverage your own unique background and connections to imagine a new technology.

Where do you see your career developing?

Everyone needs a thermal systems engineer. Batteries, computer chips, and turbine blades all need to be cooled.

Power plants need to be designed and constructed for maximum efficiency and lowest cost. Building energy efficiency needs to be optimized. Because of this, my career as a thermal systems engineer can go anywhere.

In the near future, I will start employment at a major company in Silicon Valley, California. After being in industry for a few years, I hope to become faculty at a university where I can do research, teach, and mentor graduate students, because I enjoy sharing my ideas as much as I enjoy developing them.

What are the challenges of this industry?

As is the case in any industry, any new technology needs to be cost competitive with existing technologies. It is especially difficult to do this in the AC&R industry because the price of vapor compression air conditioning units is already quite low, and so is the cost of electricity.

Compounding this challenge is consumer acceptance of a new technology. As we move to new refrigerants that are often flammable, toxic, or operate at higher pressures, there are many regulatory challenges that need to be addressed.

Blind development of technologies without consideration for these complexities leads to wasted time and effort. Therefore, the main challenge lies in developing diverse teams in industry that can tackle all parts of the problem at once.

What are the benefits of being in your role?

While my position as an ARPA-E Fellow includes many benefits like extensive travel, high visibility, an independent work schedule, freedom of thought, and interaction with leaders in academia and industry, probably the most valuable benefit of the Fellowship is the ability to see today’s most cutting-edge technologies.

As a Fellow, I am developing an intimate understanding of the work going on at national labs, large and small companies, and university campuses today, such that I know what is going to be published and developed in the next year or two.

This gives me the ability to predict where various industries will go in the next threeto-five years, amplifying my ability to be an informed and effective technical leader.

What industry competitions or events have you participated in?

None specifically in industry.

In high school, I participated in FIRSTÂ robotics.

THE IMPORTANCE OF APPRENTICESHIPS The ACR Journal welcomed Ernie Bate, Managing Director, Sauermann UK to its head office in Bourne to discuss how far his business has come and to understand why they see the ACR Trainee of the Year Awards (TOTY) as such a vital event for the sector.

Tell us about Ernie Bate

I trained as an Engineer via an apprenticeship scheme many years ago now. These beginnings actually led nicely into why Sauermann UK is committed ‘4 year’ sponsors of TOTY. It was always thought that the natural progression of engineering was once you’d done your time on the shop floor the next step was into the offices. I took this step and became a qualified draftsman. It soon became clear this route wasn’t for me. I’m probably too much of a people person and missed the interaction I’d had previously.

I chose to take voluntary redundancy and spent a year travelling, much of this time in Australia, working my way around the country. I learned many life skills in that time.

Once back, I then went into sales for a trade magazine based in the North of the country. This was an interesting time and over the 4 years I became attached to the industry. The career path I anticipated taking was actually moving in a different direction, so I decided to move on. It was when I was saying my ‘goodbye’s’ to a client that I was offered another opportunity, different to the one I was going to.

My contact at WJ Furse Ltd in Nottingham, had said he was shocked to see me leaving and promptly offered me a positon within their organisation.

After an exciting and educational 3 years I then helped form another well-known Nottingham based company. Then of course I moved across to ACES before my final move.

such great support from the industry that we outgrew that space within 6 months.

We promptly relocated to Blackpool, where the business has subsequently moved into becoming a key supplier to the HVACR industry. Continuous growth and development sees our new training room opening at the end of 2016. We will invite a selection of shortlisted and winning entrants from TOTY 2016 to the premises for a hands-on training day in 2017. This will be followed by a team building and networking opportunity (a chance to let their hair down).

What’s next for Sauermann UK?

It’s exciting times for the company. Apart from the hands-on training suite, we will have launched our new acquisition, which is an instrumentation manufacturer. More information on products and services provided will be ready soon.

In addition to this, we will continue with our strategy of working with key distribution partners and OEM’s.

Why would our readers buy a Sauermann Pump?

Inside every mould is a pump. Every pump inside our moulds is a Sauermann Pump, manufactured by us, not for us. Our R&D department is second to none, which means that our customers benefit from increased performance, reliability and low running sound levels.

Why support TOTY (ACR Trainee of the Year)?

Ernie Bate

me in excellent stead and brought me to where I am today, Managing Director of a very successful company with new and exciting challenges ahead.

This industry luncheon is very important. It has always been seen as the networking event for higher management people, an excellent platform for sharing knowledge and vision between themselves. But also for the apprentices lucky enough to attend. Held at The Belfry, Sutton Coldfield every December, that added to the fact it is a ‘not for profit’ event makes it a definite industry diary date. A way to wind down and treat valued clients and staff just before Christmas.

Sauermann UK are proud to have signed up to a 4 year sponsorship deal. This event is all about the students recently there haven’t been enough apprenticeships businesses had struggled to offer them.

There had also been a school of thought as ‘why bother to train them, then once qualified go somewhere else’. Fortunately this tide is changing. If you don’t train them they will go elsewhere.

My training consisted of modules which had to be completed. Loyalty was cultured and I felt there was a value to my apprenticeship. Rewarding apprentices at this event helps to encourage and add to that value.

I look forward to seeing you all there!

What’s the history of Sauermann UK?

It was after this time, October 2004, that I brought Sauermann to the UK. We had a small office, based in Preston. It was due to

Coral First Past the P

DAIKIN’S ‘INVISIBLE’ A After seeing the launch of the VRV i-series at a Daikin event, a new Hertfordshire Coral betting shop is the first site in the

inding a suitable location for outdoor climate control units is a reoccurring issue for urbanbased stores and offices, with the units traditionally located on rooftops or at the back of premises.

This was the exact issue faced by a new Coral store in the town centre of Hatfield. Lacking sufficient space for an outdoor unit, the 78m2 store could not install a traditional VRV climate control system.

Looking for a new system, Coral attended a Daikin product launch presentation. After the event, Coral quickly expressed an interest in the ‘invisible’ VRV i-series as a climate control solution for the planned premises at Hatfield.

Specifically designed for VRV applications where outdoor units are not possible due to space limitations, architectural considerations or planning constraints, the Daikin VRV i-series is the ideal solution. Overcoming the issue of outdoor space, the innovative unit is mounted entirely indoors with only a grille visible outside – and even that can be hidden from public view.

Splitting the ‘outdoor’ unit in two, the VRV i-series has a small-footprint compressor unit that is just 701mm high and needs only 600x554mm of floor space.

This compact design makes it easy to install in a storeroom or back office. The separate heat exchanger unit can then be mounted in a ceiling void with air intake and discharge through a grille to the outside, providing a discrete, ‘hidden’ system,

the

UK to boast ‘invisible’ air conditioning. perfect for storefronts that do not want to compromise aesthetic appeal.

An added benefit for this particular installation was that the VRV i-series reduces the usual planning approval issues. This meant that the installation could begin as soon as possible and ensure that the store would promptly open.

A nominated contractor – IAC Service Group Limited, installed the Hatfield store’s system. A Billericay-based Daikin UK D1+ installer, IAC Service, has been installing and servicing the betting group’s air conditioning systems in London and the South East for 15 years.

Vince Mann, IAC Contracts Director, said: “The heat exchanger unit can be installed virtually anywhere as its maximum static pressure of 150Pa allows fairly lengthy suction and discharge ducts, but in this case we installed it against a grille at the rear of the premises.”

“The compressor unit serves a wall-mounted fan coil unit in the staff area and two self-cleaning Roundflow cassettes in the customer area.”

As the first UK installation of the new system, engineers from Daikin UK and Daikin Europe attended the system’s commissioning, shortly before the new betting shop officially opened.

A complete climate control solution, the Coral’s 5hp i-series has nominal capacity of 14kW in heating and cooling, Coefficient of Performance (COP) of 3.8 and Energy Efficient Ratio (EER) of 3.20.

Connecting to a maximum of 10 indoor units from the full VRV IV range as well as

DAikin VRV.indd 39

air handling units and Biddle air curtains, the VRV i-series is suitable for traditional VRV applications.

Installation Benefits

Offering significant flexibility with regards to the system installation, the maximum piping length between the compressor and last indoor unit is 70 metres.

Furthermore, the height difference between the compressor and indoor units can be up to 30 metres as long as the difference between highest and lowest indoor units is limited to 15 metres. This allows for the system to be completely hidden within the building, and be invisible to the public eye.

Easy to transport and handle due to the unit’s compact design, the VRV i-series offers a simple and fast installation, reducing the potential for any onsite disruption or delays.

Operating at just 47dBa, both the heat exchanger unit and the compressor cause minimal disturbance, ideal for urban retail and commercial buildings with nearby residential properties.

Alongside the installation benefits the compact unit presents, inside the store the benefits continue, for example, the self-cleaning Roundflow cassette has an automatic daily cleaning cycle to prevent dust accumulations on its décor panel.

Following a year-long trial at Coral’s Wolverhampton branch, the cassette has become Coral’s product of choice after results showed it to be 49% more cost efficient to run than a traditional Roundflow cassette with a standard décor panel.

IDEAL FOR THE

BRITISH SUMMER... …and Spring, Autumn, and Winter

Colin Goode

ujitsu VRF (variable refrigerant flow) air conditioning systems are the ideal, cost effective solution for the British climate given their ability to heat simultaneously and cool, combined with design flexibility and highly efficient performance.

Welcome to another British summer!

The weather and the British obsession with talking about it – often puzzles outsiders until they experience for themselves all four seasons in one week.

For heating and cooling engineers, interest in the variability of the British weather is far more than a passing cultural habit. The challenges of the very real potential for part of a building requiring cooling, while another area in the same building demands heat.

Many buildings require both heating and cooling during some part of the year, and there are those that require both at the same time. There are two types of VRF systems. It is important to understand the difference between them. The two types of VRF systems are the 2-pipe, and the 3-pipe or heat recovery type.

About 3-Pipe VRF Systems

Three-pipe VRF systems, such as the Fujitsu VR-II models, can heat and cool at the same time which is a requirement for many buildings in the UK. On autumn, summer and even winter days, one side of a building can be cold, while sun streaming through the windows on the other can make those rooms too warm; a three-pipe VRF system can cool the warm side at the same time as it is heating the cool side.

With the use of heat recovery, it can move the heat via the refrigerant pipework from the warm to the cold side and save considerable amounts of energy.

In an ideal 50/50 cooling/heat scenario, the overall VRF system efficiency (kW power input vs. kW Heat / Cool output) can be as high as 7.6 or 760%.

About 2-Pipe Systems

Two-pipe VRFs, such as the Fujitsu Airstage V-III, can cool or heat, but not both at the same time. These systems are particularly suitable for cooling and heating homes, smaller offices or buildings, or buildings that just need cooling where a heating system already exists.

The design approach for 2 and 3-pipe VRF systems is (should be) completely different.

For 2-pipe heat or cooling systems, the outdoor units should serve indoor units that are all on the same side/face of a building or all internal areas.

Each room should also have a similar heat load profile & occupancy levels.

Internal/external or north/south areas should never be served by the same outdoor unit because this will result in simultaneous heat/cool demands which a 2-pipe VRF system cannot accommodate.

The only exception to this would be if a 2-pipe VRF system you used for cooling only, in which case the same system can serve internal/external or north/ south areas.

and heating at the same time you should connect to the same outdoor unit/system.

VRF air conditioning systems are inherently efficient, especially the 3-pipe heat recovery variant. However, to achieve maximum efficiency, the VRF system as a whole must be designed to access the potential for heat recovery.

An accurate heat load/loss calculation of the building will reveal the areas that have simultaneous heating and cooling requirements. You see this in the spring and autumn when north facing areas require some heating and south/west & internal areas need some cooling.

Some interior areas can also require cooling in winter when perimeter areas need heating. To maximise heat recovery potential, you should include these areas on the same 3-pipe heat recovery VRF system. In this way, the possibility of heat recovery from a zone to another is maximised.

Different Design Approach with 2-Pipe Systems

This design philosophy for 3-pipe heat recovery VRF systems is the complete opposite to that required for 2-pipe systems which can only heat or cool i.e. not simultaneously. For 2-pipe changeover, VRF heat pump systems demands for cooling & heating at the same must be avoided at all cost.

Only include rooms with similar heating/cooling loads that occur at the same time & rooms on the same side/ orientation of a building should be on the same 2-pipe system. Failure to observe

this fundamental requirement for a 2-pipe system will cause temperature control problems and complaints from dissatisfied occupants.

The ideal scenario to achieve maximum energy efficiency in a 3-pipe Heat Recovery VRF system is a 50/50 demand for both cooling & heating at the same time.

VRF Benefits

VRF systems are very easy to retrofit into existing buildings. Their low running costs, flexibility, the speed of installation and complete control system make them the system of choice for both new and old buildings.

It is far easier and quicker to route relatively small diameter refrigerant pipework around the building than large ducts or water pipes.

Theoretically, there is no building too small for VRF and systems such as the Fujitsu 14kW J-IIS Mini VRF outdoor unit is specifically designed to occupy the smallest possible footprint so that you can site them on balconies, in gardens, on small flat roofs or even on outside walls on suitable brackets.

So, while the general population will continue to debate whether sunglasses, an umbrella, or an overcoat is required, heating and cooling engineers can discuss the most versatile and cost-effective VRF solution for the majority of buildings all year round.

A guide to...

VRF COMMISSIONING The commissioning of a piece of equipment is a standard procedure across the industry, however if done incorrectly, customers can find themselves at risk of unexpected equipment failure and downtime leading to extensive costs.

P

ete Mills, Commercial Technical Operations Manager at Bosch Commercial and Industrial outlines the process of VRF commissioning and what Bosch offers.

The commissioning process of any installation is extremely important as it provides official certification and confirmation that a piece of equipment is performing as it should. It takes place once the installation is complete and is usually performed by an engineer on-site, who will take a systematic approach to testing the piece of equipment.

What is involved?

For our VRF systems, the commissioning process begins with a pressure test using nitrogen to find leaks, testing the system at a certain level. It is kept in this condition for a minimum of 24 hours to ensure it can maintain the same pressure level, before the nitrogen is allowed to die out. This first section consists of three elements – a leak test, a pressure test and a strength test. Although the commissioning process in general is fairly standard across the industry, customers should ask what the system’s pressure requirements are, as this will vary depending on the manufacturer.

The next step is a vacuum test which is done at 0.5 Torr for an hour to dehydrate the system and ensure it is free of any dirt or moisture. A specific amount of refrigerant is then added into the system, which is likely to vary between manufacturers.

The final step is to test the equipment – the power is switched on for a minimum of 12 hours so the outdoor unit can heat

Worcester Bosch.indd 43

up. From there, the cooling and heating is tested which is essential for ensuring the system is ready for the customer to use.

Most manufacturers use a standard process which consists of a regular pressure test followed by a vacuum.

Although it is not a legislative requirement, Bosch engineers champion using a triple evacuation system whereby there is a pressure test followed by a vacuum test and this process is repeated three times. This is the best way to be certain that any dirt or moisture which may have found its way into the system has been removed and delivers far better results than a standard vacuum process.

Free VRF commissioning

Having entered the air conditioning market earlier this year, Bosch has introduced a free commissioning service to its VRF offering, with every first project purchase. This ensures that consultants, contractors, and engineers can reap the benefits of a flexible heating and cooling system as soon after the installation as possible.

VRF is a new product to Bosch and one that a lot of our customers wouldn’t have necessarily seen or used before, so we

want to offer our customers a relaxed approach to the commissioning process and to the Bosch brand, as a completely new entrant into the VRF market. The commissioning process can vary from one manufacturer’s VRF system to the next, so we’re keen to eliminate any potential inconsistencies by having one of our own engineers commission the system at no extra cost.

The service we offer also includes onsite training which consists of hints and tips about how best to benefit from the installation. When we come out to site, we teach the customer how to commission and test a VRF system to ensure it is set up correctly and to make the customer feels more at ease with our equipment.

Ultimately, through a thorough commissioning process and on-site training, engineers and maintenance staff can ensure their VRF system will make a real difference to the comfort and efficiency levels within their building. www.bosch-industrial.co.uk or call 0330 123 3004.

CREATURES GREAT AND SMALL

BENEFITTING FROM RENEWABLE HEATING An expanding veterinary practice in Norfolk is benefitting from heating and hot water with reduced energy bills, thanks to a ground source heat pump installed by the renewable heating experts, Finn Geotherm.

Finn Geotherm was shortlisted in four categories in

the 2016 National ACR & Heat Pump Awards.

Hannah Kelly, owner of Wood Farm Vets, started the practice in 2014 to care for large and small animals.

Initially, Hannah ran the practice from her home, a farmhouse in Wymondham, South Norfolk, but rapidly outgrew the premises.

“The vets really started in the back of my car but quickly moved into my farm office,” explains Hannah. “We soon began taking over the various other rooms in the house, from the kitchen to the hallway, as more and more patients came in. When my lounge became the waiting room, I knew we had to find a better solution.”

Horses to hamsters

Hannah began to renovate a Grade II listed former corn barn on her land to create a modern mixed practice, capable of treating all animals from horses to hamsters on-site. As part of the renovation, Hannah needed a heating and hot water system that would be able to cope with the demands of her busy business, as well as servicing her house, which had previously relied on an oil boiler.

Wood Farm Vets wanted a sustainable and future-proof solution so ground source heating was ideal.

With a generous amount of land available for a 1700m collector loop, Finn Geotherm specified and installed two Lämpöässä Esi 14 ground source heat pumps with a 1000 litre Superheat thermal store. A former outhouse, complete with built-in bread oven, was transformed into the plant house for the pumps and thermal store. The vets had both underfloor heating and radiators installed to work with the new heat pump, while Hannah’s house used its existing radiators. While the single

phase electricity in the premises initially presented Finn Geotherm with a bit of a challenge, the careful specification of a system with two heat pumps working in tandem achieves outputs of around 30kW, which is way above other similar systems.

“I am so pleased with my ground source heat pump,” said Hannah. “The entire practice is warm – even dogs in the kennels can enjoy underfloor heating – and my team and I have access to up to half a tonne of hot water in one hit if we need it, which is brilliant when we’re dealing with larger animal patients. My house has never been warmer too, so after a hard day at work, I know I can return to warm home and don’t even have to think about lighting the fire.”

Benefit from RHI

The installation at Wood Farm Vets and Hannah’s home will also benefit from the government’s Renewable Heat Incentive (RHI), a Government financial incentive which rewards people and businesses for opting for renewable energy.

NEW APPROACH IS CRITICAL

FOR INSECT BREEDING Highly efficient and eco-friendly heat pump technology from Samsung Electronics was the commercial heating solution for local UK business, Peregrine Livefoods, an insect breeding plant based in Harlow, Essex.

A

s a business that runs and relies on a consistent temperature of internal heating to breed insects for the pet food market, when faced with a significant construction of the two storey and 17m square factory, with six 11x6m breeding rooms, a new approach to heating was critical for Peregrine Livefoods.

Previously the breeding rooms which house the insects were heated using oil filled radiators causing a number of problems, including high running costs, intensive labour requirements to check and reset the thermostats daily, and inconsistent heat across the rooms. The insufficient heating resulted in varied growth rates of the insects requiring increased labour to continually move the breeding boxes around.

To overcome these problems a system was designed by Aztec Solar Engineering with assistance from The Energy Lab and Freedom Heat Pumps.

The solution included installing a pair of high performing and economical Samsung 16kW EHS Air Source Heat Pumps, heating a 1000 litre buffer tank to 480C. Each of the breeding rooms had 11 1200x600 radiators installed with independent circuits taking energy from the central buffer. Each circuit is controlled by an ESBE GRA111 blending valve, reading temperatures at four

locations on the system, providing a consistent heat required by the factory.

Temperature within 0.5 degrees

The project was taken on to heat three rooms used for the insect breeding process within the factory and required to be kept within 0.5 of a degree at all times.

The Samsung 16kW EHS Air Source Heat Pumps installed are eco-friendly, compatible with green energy systems and are highly efficient using an all-in-one system with high performing heat pump technology, ideal for an environment requiring such precision heating.

The Samsung 16kW EHS Air Source Heat Pump system met all requirements, being compact, quiet and energy-efficient, along with features and controls that suited this unique business. The weather compensation feature of the heat pumps was introduced as the seasons changed and summer arrived, with the system bringing the buffer temperature down to prevent the breeding rooms temperatures from over running. This allowed the breeding rooms to be controlled at 33.40C with a consistent and even temperature across the room ideal for the insect breeding facility.

“Peregrine Live foods faced a challenge in sourcing the most efficient and cost effective solution for heating their insect breeding factory,” explained Paul Brooks Director of Aztec Solar Engineering. “When taking on this project, we understood the requirements for a high performance and economic heat pump technology and believed Samsung’s range of EHS Air Source Heat Pumps would be ideal for this business.

The Samsung heat pumps ultimately solved all the limitations of the original and expensive method at a much lower electricity cost and higher performance.”

No longer struggling after 20 years!

The Samsung heat pump system is now in its second year running automatically and has met the satisfaction of Peregrine’s needs after struggling for almost two decades. s

236% RETURN?! £862k boost for livestock auctioneer in renewables overhaul.

A

n auction house in Northumberland is set to make a 236% return on investment, reaping an estimated £862,000 in energy savings and commercial RHI payments over the next 20 years, after installing solar PV panels and a NIBE ground source heat pump system.

Located in the historic market town of Hexham (25 miles west of Newcastle), Hexham and Northern Marts specialises in the auction of livestock and cattle to farmers across the north east of England. In a bid to slash overheads and diversify its revenue streams, the business decided it was time to replace its old gas-fired heating system with a more sustainable alternative. One that would not only reduce energy consumption and running costs, but also earn additional income through the Government’s Renewable Heat Incentive (RHI). Minimising any impact on day-today operations during the transition was another key consideration. Managing Director, Robert Addison, tasked renewable energy specialist and NIBE VIP installer, Calibrate Energy Engineering, with finding the right solution to meet the heating and hot water demands of the 112,050 sq ft building.

The team at Calibrate specified, designed and installed a 300 kW renewable heating system made up of five 60 kW NIBE F1345 ground source heat pump (GSHP) units. They paired this with a 50 kW solar PV array, fitted to the roof of the main pen area, which partially powers the NIBE GSHP system. The in-ground heat collectors required for the GSHP were laid in the fields around the buildings, with the controls units sited in a prefabricated plant room to the rear of the premises.

Replace an energy guzzling system

Susie McDonald, Director at Calibrate Energy Engineering, explains: “Hexham and Northern Marts’ priority was to replace its energy-guzzling gas heating system with one that would deliver a significant, tangible return on investment, without disrupting trading. By opting for the NIBE GSHP units and solar PV panels, we were able to do just that. Both systems are situated outdoors, away from the bustle of the auction house, and use their natural surroundings as an energy source.

“The GSHP system generates enough renewable energy to heat the sales centre (including its reception area and three sales rings), while the solar PV array provides renewable electricity to complement it. What’s more, the installation took just three months from start to finish, and during this time it was business as usual for Hexham and Northern Marts.”

Meets Demand

Docked together in a cascade for greater output capacity, the five NIBE F1345 GSHP units now meet 95% of Hexham and Northern Marts’ 394,000 kW/h annual heating and hot water demand, with a seasonal performance factor (SPF) of 3.38. Meanwhile, the 50 kW solar PV array generates enough free electricity to offset a significant 50% of the power needed to run the GSHP system.

Instant Reductions

Robert Addison, Managing Director at Hexham and Northern Marts, says: “We couldn’t be happier with our new renewable heat and power sources. As well as delivering instant reductions in energy usage and subsequent savings on heating bills, the NIBE GSHP solution is providing us with a steady stream of income for the next two decades, thanks to the RHI. The power produced by the solar PV panels is an added bonus, and makes running the heat pump system even more cost-effective.

“As a result, we’re expecting to see returns of more than double our original investment over the next 20 years – which is absolutely invaluable from a business point of view. Not only this, but we’ve got an efficient, reliable renewables setup that’s fit for the future, and will continue to deliver ongoing savings for years to come. Working with the Calibrate team

OUTDOOR CENTRE HEATED

USING NEARBY RIVER Haven Banks is a £5.6 million outdoor education and training facility located on Exeter’s historic canal-side. It provides 25,000 young people a year with the chance to participate in courses on sailing, canoeing, kayaking, windsurfing, climbing, caving, orienteering, archery, raft building, team building and first aid.

S

pecially built in 2013, renewable energy was an essential part of the building’s design specification. Kensa Heat Pumps were able to provide a sustainable and efficient supply of heating and hot water by extracting heat energy from the River Exe using ground source heat pumps.

Being able to extract heat energy from the river made the system particularly efficient, as water is an excellent conductor and has a higher heat transfer rate than the ground.

The river current provides a replenishing energy source and as there was no need to dig any trenches or boreholes, the installation cost was greatly reduced. The building has underfloor heating installed throughout, which further increases the efficiency of the heat pump due to its low outlet temperature.

Due to the large size of the building and its very high heat load, Kensa supplied two 30kW Plantroom units to supply heating and hot water to the activity centre. The heat pumps are housed in a plant room and controlled by a bespoke building management system linked to

a gas boiler which only operates if the ground source heat pump system needs additional back up.

Kensa assembled ten specially designed ‘pond mats’ made up of 250m of coiled pipes mounted on stainless steel frames. Each pond mat was sailed over to the quayside next to the building where they were submerged in the river and connected to the centre’s heat pumps one by one.

As the granite wall on the canal-side is protected, the pipework and manifolds that connect the pond mats to the heat pumps are housed in a custom built wooden shelter, therefore avoiding any drilling through or under the wall.

Exeter-based renewable company, SunGift Solar, were responsible for the installation which took around seven days.

Jamie Burnham from SunGift Solar said: “This was a particularly exciting project for us as we were harnessing power from one of our most affluent local resources – the River Exe. We’ve worked with Kensa many times before. Overall, the system was simple to install and very similar to the domestic kits we are familiar with, however. it was a bit tricky trying to manipulate coils of pipe from a floating pontoon on a windy day in January!”

He continues: “Kensa provided us with lots of great advice prior to the installation and everything worked out as planned. The Kensa kit has delivered well, as always, and we continue to use them as our preferred ground source heat pump supplier.”

TESCO HUFF AND PUFF GOLF DAY ADDS TO CHARITY FUNDS

The 2016 Tesco Huff and Puff Charity Golf Day on 16th June 2016 added yet more funds to its charity, with £5,750 raised on the day, and a total of £59,000 to date.

The event, organised by the tireless John Hughes, has raised over £53,000 in the six years since it started. Numerous industry teams meet at Greetham Valley golf course in Rutland to battle for the nearest to the post and furthest drive prizes, and the

overall winner prize. All the teams are suppliers to Tesco for their engineering requirements across the stores.

This year, the rains and the winds held off until the ACR Journal editor’s team made it to the 18th hole. At which point, the heavens opened sending torrents of rainwater across the green making it impossible to play. It was just as well. The editor, Will Hawkins, had just about run out of balls.

PRECISION REFRIGERATION SUPPORTS BRITISH TRIATHLETE British manufacturer Precision Refrigeration is helping triathlete Francesca Hall with her aims to win a gold medal at the 2024 Olympics, the company announced this week.

The 21-year old already represents Team GB and she will be competing in Austria in the European Middle Distance Championships, followed by the Zell-am-See Ironman in the Netherlands. That triathlon covers over 70 miles including a 1.9 km swim and 21 km run.

Francesca finished 5th in her age group at the ITU Duathlon World championships at Aviles in Spain.

She said: “Precision is helping me cover the cost of competing in the events – it’s a huge help. Athletes like me just couldn’t afford to take part in these events without support from family, friends and sponsors. My aims are to compete as an elite/pro at the 70.3 mile distance and, ultimately, to represent Great Britain at the Olympics.”

Francesca is no stranger to commercial refrigeration and Precision. Her Dad, Jeremy, used to be the company’s sales director.

She concluded: “Here’s hoping I can repay them by winning a few races.”

₀ Terry March retires

₀ Integral Grows HVAC Team

Industry veteran Terry March is to retire from the industry after a career spanning more than 46 years, his employer Emerson Climate Technologies announced this week.

Terry joined Prestcold in 1969 as a technician apprentice in the days when the Prestcold Theale plant produced semi-hermetic reciprocating compressors under licence from Copeland Corporation in the USA. Throughout his tenure, Terry was directly involved in the roll-out of a number of important technology developments, none more so than the early launch and promotion of scroll technology for both air-conditioning and refrigeration applications. The Emerson organisation wishes him all the best for a long and happy retirement.

Integral, the buildings services firm, is developing its industrial refrigeration and HVAC team with the recent hire of Ian Hussey into the team.

Ian has the task of developing the company’s specialised UK HVAC (heating, ventilation and air conditioning) business. Ian has been in the industry for over 30 years, where he worked for Denco Happel in their compressed air drying, industrial lubrication, and process cooling division.

Furthermore, he has deep experience in precision air conditioning designing computer rooms and delivering clean room technologies.
