22 Essential Information for the Air Conditioning and Refrigeration Industry

Keeping it clean as well as cool

Even at the height of summer, it’s worth re�ecting that keeping people and things cool is only one of the crucial areas of expertise this sector has to o�er.

The recent National Clean Air Day again highlighted the problems of outdoor pollution and campaigners, backed by BESA, have called for agreed Indoor Air Quality levels to become part of the planning process.

BESA also used the event to announce plans for the first comprehensive IAQ standard and there is a wealth of knowledge out there to aid this process. We have recently carried a range of articles looking at many aspects of air management and IAQ and this issue includes a report looking at the importance of proper ventilation in schools.

Clean air benefits everyone and, encouragingly, there seems to be a growing awareness of the need for more of our buildings to become ‘safe havens’ from pollution.

ASPEN PUMPS ACQUIRES Aspen Pumps has acquired JAVAC UK, the air conditioning and refrigeration tool specialist. Founded in 1973 by the Davies family, JAVAC UK has grown significantly from its early days as a niche supplier of refrigeration and vacuum equipment.

Adrian Thompson, CEO of Aspen Pumps, said: “We are delighted to announce that we have formed a closer relationship with JAVAC UK. It’s a natural fit for both businesses; we share the same core values.

Steve and Scott Davies have done an excellent job in making JAVAC the UK’s number one.”

JAVAC UK Managing Director Steve Davies and Sales Director Scott Davies

UK

are both committed to remaining with the business. Talks have been going on for around 12 months and the deal is expected to see new investment at the Middlesbrough-based business.

Steve said: “This is a great opportunity for JAVAC UK and Aspen to form an unbeatable partnership within the refrigeration and air conditioning industry.

We are all excited at the prospect and our business can now only develop and grow.”

JAVAC UK is Aspen Pumps’ second investment within two months, following the acquisition of Salina SAS (France) in May. JAVAC Pty Ltd, the Australia-based business, is not part of the transition and remains a separate company under private ownership.

ECOSTAR PERFORMANCE

BOOSTS UK ATHLETES Bitzer Ecostar systems are at the heart of major investment to support UK athletes. Around a dozen hightech sports laboratories have been equipped with temperature-controlled training facilities, enabling athletes to train in controlled conditions that can mimic those experienced anywhere in the world.

Refrigeration contractor Cold Control installed a system at the University of Kent, enabling sports scientists to control temperature, humidity and oxygen levels for athletes in training.

Working with Tiss Environmental, Cold Control designed the refrigeration system around a Bitzer Ecostar LHV6 packaged unit, which comes equipped with a built-in inverter. It is designed to maintain conditions between -25°c and 50°c, with varying levels of relative humidity and atmospheric oxygen within the chamber.

The 4m x 4m x 3.1m controlled space has a fully insulated envelope, designed to freezer store standards, with a

heated floor and cool-running LED lighting. Conditions in the test chamber are controlled by bespoke software, developed by Tiss Environmental, which integrates with the Ecostar control system, and enables researchers to control conditions to very tight tolerances.

CLIMATE CENTER INVESTS IN R448A Climate Center is now stocking R448A, an alternative to R404A, in all 55 branches nationwide. The race is on ahead of the R404A ban in 2020 to find alternatives for refrigeration and the significant stock investment aims to make it easy for customers to access this alternative before demand for R404A outstrips supply.

The changes to the F-Gas Regulations came into force on 1 January 2015 with the aim of encouraging users to use refrigerants with a lower global warming potential (GWP). From 2020 a ban on using new refrigerants with a GWP higher than 2500 for servicing most commercial refrigeration systems and in new stationay refrigeration systems comes into effect.

Robert Franklin, sales director at Climate Center, said: “If companies don’t act now, they run the risk of not being able to access the higher GWP refrigerants as quota reductions limit availability of high GWP blends.” www.climatecenter.co.uk

ICS COOL ENERGY ADDED TO GREEN BUSINESS DIRECTORY

ICS Cool Energy has been added to the Carbon Trust’s Green Business Directory as an accredited supplier.

In order to achieve accreditation, suppliers must meet particular criteria set out by the trust in order to prove they are able to deliver appropriate energy efficient solutions consistently.

Sales Director Richard Metcalfe said: “Finding a suitable and energy efficient temperature control solution can be a complex task so the scheme is of great benefit for end-users who are given clear guidance as to trusted suppliers they can approach and can access the latest energy efficient opportunities and equipment.” www.icscoolenergy.com

LG’s new ARTCOOL Mirror unit

LG has launched a new range of wall mounted air conditioning units with new features including embedded Wi-Fi and compatibility with its multi-split range.

In addition, the 10-year compressor warranty that already applies to its single split wall mount units is now extended to include the multi split range.

The range includes the new outlook ARTCOOL Mirror, the Deluxe and the Standard Plus models. All units are A++ in cooling, and have added to the ranges existing high efficiency rating with A+ in heating, along with active energy control, and smart diagnosis.

Artcool and Deluxe models are also equipped with Plasmaster Ionizer Plus filters, said to sterilise up to 99.9% of all bacteria and deodorize the air .

All three units feature embedded Wi-Fi, enabling users to access air conditioners via smart internet devices such as Android or iOS based mobile phones.

Smart diagnosis allows users to check set up, installation, troubleshooting and other related information direct from a smartphone. This is achieved by utilising LG’s ‘LG Smart ThinQ’ App. partner.lge.com/uk

CRS INCREASES PORTABLE FLEET Carrier Rental Systems has invested in a new fleet of 400 high-performance portable air conditioning units to meet summer demand.

The ACU 3.5kW comes with a discharge hose up to 3m long, giving flexibility of placement within rooms and buildings. Extended cable lengths of 2m are also supplied.

A built-in condensate management system overcomes the need to manually dispose of accumulated condensate.

Moisture is evaporated by heat generated by the system’s condenser coil and also ejected as warm/damp air via the extraction duct.

In addition to the standard cooling mode, the unit features a dehumidification setting with the capacity to remove up to 54 litres per day. www.carrierrentalsystems.co.uk

SPIN BITS PROMISE SPEEDY

FLARING AND SWAGING Drill bits allowing �aring and swaging to be completed in seconds are now available in the UK from Advanced Engineering. The Spin technology is compatible with the most common diameters of HVAC tubing (1/4”, 3/8” and 1/2” with wall thickness up to .8mm and 1.0mm for 5/8”) and suggested for use with drills and screwdrivers that are 1,800 RPM and 500 watts or higher.

The bits have been designed so that they are the perfect dimensions for standard tubing, claiming to ensure an even wall thickness on the pipe, and have a collar on the bit that prevents it from going deeper than necessary. Flares made with Spin tools are compatible with high-pressure refrigerants and, because the method takes copper above recrystallisation temperature, drill bits can be used with hard or soft copper tubing. Tools have been optimised for use with soft-drawn copper.

Traditional cold working swaging and �aring can result in hardening, a leading cause of microscopic cracks and leaks.

The Spin method heats up the tube through friction, with no hardening of the expansion area. www.advancedengineering.co.uk

GLOBAL FOCUS ON HFO REFRIGERANTS

An international conference looking at the use of HFO refrigerants will be hosted by the IOR in Birmingham next year. The inaugural IIR International Conference on 2-5 September 2018 will bring together global experience on the use of low �ammable A2L classi�cation refrigerants.

It will cover essential information for designers, manufacturers, end users and installers about characteristics of low GWP refrigerants, system and component design, lubricants, �ammability, legislation, codes of practice and standards.

The event is at the Austin Court Conference Centre in central Birmingham. For more information or to register an interest, visit: www.hfo2018.com

‘TRAINING KEY TO FUTURE OF BUILDING CONTROLS INDUSTRY’

SONTAY OPENING

NEW OFFICE IN UAE Field controls specialist Sontay is opening a new o�ce in the United Arab Emirates, with Ali Jabr appointed as Middle East Area Sales Manager following the retirement of John Cameron.

Sandy Damm, Sontay Managing Director, said: “This is a fantastic growth step and shows how our dedication and hard work in the area is coming to fruition. I would like to thank John Cameron for his loyal service and commitment. He has built up a great customer network in the Middle East, and we wish him all the best in his retirement” www.sontay.com

The Building Controls Association (BCIA) believes the key to a sustainable future in the industry is to invest in young people and �nd skilled role models for the next generation.

Technical quali�cations called T-levels will be introduced next year for 16-19 year olds following investment from the government. Construction and engineering are set to be two of the key areas which will bene�t from this.

Malcolm Anson, President of the BCIA, said: ” We can all play a signi�cant role in helping shape the future of the building controls industry. Let’s unearth the next crop of controls engineers and demonstrate our passion for the sector.” www.bcia.co.uk

IAQ COULD BECOME PLANNING ISSUE Developers could soon be required to achieve an agreed standard of Indoor Air Quality (IAQ) to gain planning permission for new buildings. The Mayor of London is being urged to include IAQ levels in his revised London Plan for buildings over a certain size following intensive lobbying from the Clean Air in London campaign.

The proposal has the backing of the Building Engineering Services

Association (BESA), which hosted an IAQ event on Clean Air Day in June. Chief Executive Paul McLaughlin said: “The beauty of focussing on IAQ is that it can make an immediate di�erence. While the lengthy debates and legal challenges over how to address outdoor air pollution rumble on, our industry can make an instant impact by putting measures in place that protect the health of building occupants.”

MITSUBISHI’S MR SLIM POWER WITH R32

Mitsubishi Electric has launched a new range of air conditioning units utilising R32 refrigerant at the same price as the equivalent R410A units. The R32 Mr Slim Power Inverter split type modelsare the second product range in the company’s UK line-up to utilise R32 refrigerant – which has a low global warming potential (GWP).

The range includes ten outdoor units o�ering single-phase and 3-phase options, with a capacity range from 3.5 to 14kW. 25 individual indoor units are also available as ceiling cassettes, ceiling concealed ducted, wall-mounted and ceiling suspended models. Mr Slim Power Inverters are also available in twin and triple multi-split con�gurations delivering complete �exibility for system designers.

Mitsubishi says the systems o�er better performance at the same price and also o�er longer pipe runs with 100 metres available on the 10kW, 12.5kW and 14kW models – 25 metres longer than the equivalent R410A versions and the longest currently available on the market. This includes a 30 metre lift that is unique in the UK. The longer pipe runs are designed to make Mr Slim R32 more �exible and allow systems to be installed where previous site restrictions would not allow. www.timeforr32.co.uk/pr5

SAVING ENERGY IN TIGHT SPACES

LATEST TECHNOLOGY FOR HOTEL PROJECT Coolair Equipment has made use of the latest pipework technology during the renovation of a top London hotel. The company’s Maidstone o�ce installed a new heating and cooling system with aluminium piping and joints to serve all 326 bedrooms of the Sheraton Grand London Park Lane.

Instead of using copper tubing that requires hot working, Coolair installed a new Mitsubishi Electric variable refrigerant flow (VRF) heat recovery system, switch room, generator, and air handling units connected to all guest rooms and suites through the largest European use of the Reflok pipe system.

It uses precision compression instead of brazing for pipe coupling.

The £1m commission from international interior fit-out specialist Beck Interiors was part of a multi-million-pound refurbishment of the 1920s art deco Mayfair hotel, carried out in two phases over two years while the rest of the five-star hotel remained fully operational.

Fan and motor manufacturer ebm-papst has unveiled a compact energy-saving fan for use in the rear walls of refrigerated display cases.

Fans in refrigerated and deep-freeze cabinets are operated almost continuously, so they o�er especially large potential energy savings.

The energy-saving fan from ebm-papst is now available with a diagonal impeller for tight spaces.

Expected lifetime is more than 40,000 hours, which equates to approximately 4.5 years of continuous operation. The manufacturer says the fan is also suitable for use in ceiling air coolers, for example

in small commercial cold storage. The diagonal positioning of the blades redirects the incoming air radially toward the outlet. The fan is available in sizes 200 and 250. www.ebmpapst.co.uk

ABB DRIVES CUTTING POOL ENERGY COSTS

A leisure centre operator has cut energy use at its pools by 30% following the installation of variable speed drives (VSDs) from ABB. Drives rated between 4 kW and 30 kW have been installed on air handling units (AHUs) and pool circulation pumps in 60 of the leisure centres operated by Places for People Leisure. This has signi�cantly reduced power consumption by matching the speed of the motors driving the applications to the required demand.

AHU fan motors in older systems are frequently oversized and will operate at full speed 100% of the time, regardless of demand. By installing VSDs, the fan speed can be reduced to match actual demand.

The ABB drives were retro�tted

by Powermaster Leisure, a company specialising in energy-saving technologies. www.abb.com

Taking time out

FOR EXHIBITIONS W

e recently held our own trade show and exhibition at the fantastic London Velodrome and I spent the day in these iconic surroundings talking to our customers, showing them new R32 products and generally chewing the fat over the industry in general.

This was our �rst venture into exhibitions and overall we were delighted with the attendance as we understand how di�cult it can be to take time away from the tools to get to what seems to be an increasing number of trade shows.

I also felt there was a real buzz about the place but maybe that was just me having too much ca�eine!

Competing demands

So where do you go for your information? And how do you choose which shows you must attend and which you simply don’t have time for?

Our MEET2017 event took place on the second day of PHEX at Alexandra Palace, so we already knew that we were making competing demands on some of our heating engineer partners but we did have a couple of customers who managed to make it to both shows.

Coming up over the next few months, there are at least six relevant industry trade shows that you could choose from – and that’s before you look at regional shows, Chamber of Commerce events, and even the numerous training courses that manufacturers such as Mitsubishi Electric put on.

Too busy?

Most of the trade shows I’ve been to over the past few years though seem to struggle to get people through the doors. Is everyone simply too busy getting on with the daily workload?

Or have the days of major exhibitions had their day?

And if you don’t manage to get to any of the trade shows aimed directly at you, where do you �nd out information on new products, tools, skills and advice that could help you sustain and grow your business?

Do let me know. We’d love some feedback on how you keep up to date with what you need to help you in your day-to-day activities.

ACRIB WEBSITE

RELAUNCHES TO HELP

FIND INFORMATION FAST

ACRIB (Air Conditioning and Refrigeration Board) has unveiled a new website featuring links and summaries to help end users and employers negotiate some of the complex areas around training, qualifications, technical issues and legislation.

New features include: ₀ an interactive map of training providers allowing users to search for centres by post code and check which qualifications or courses they offer. ₀ links to trade association databases of members to encourage end users to use reputable contractors. ₀ downloadable application forms for ACRIB SKILLcard – the voluntary ID card scheme that provides evidence of an operative’s refrigerant qualifications ₀ brief summaries of technical issues and legislation for equipment users, employers, technicians and manufacturers

Guide to industry recognised qualifications

It can be di�cult for end user and employers to keep up with the changing national quali�cations, mandatory certi�cations and short courses available.

The ACRIB website gives an overview of apprenticeships, short courses, F Gas training. It also explains how the ACRIB SKILLCard can be used to provide evidence of a technician’s quali�cations.

Those that already hold ACRIB SKILLcards, which is part of the Engineering Services SCSC scheme, know that this card is a convenient way for technicians working on RACHP equipment to show that they have the required F Gas Certi�cation. The F Gas Regulations also stipulates that equipment owners can only use F Gas Certi�ed personnel to undertake refrigerant handling activities on their equipment, so a simple card featuring the individual technician’s image and listing their F Gas certi�cate number as well as all of their other refrigerant handling quali�cations such as Hydrocarbon, Ammonia or Carbon Dioxide certi�cates is essential. The ACRIB SKILLcards are “smart-card” format which means that a

scanner can be used when the individual arrives on site to read all the quali�cations registered to that card holder. On the ACRIB website there is a full list of required and optional quali�cations that can be included on the cards. A unique feature of this card is that operatives do not need to have a Level 2 or 3 NVQ to gain the construction related operative level “white” card, if they only need this for refrigerant handling work.

Online help and guidance

The ACRIB website is a central point to access free information available from the reputable trade associations, industry professional institutes and government websites. Links to relevant guidance notes are included in regularly updated Technical and Legislation advice sections. ACRIB has also provided brief explanations of some of these requirements and technical issues as an introduction to the topics for those from non-technical backgrounds. The technical guidance section covers a range of topics such as ammonia, carbon dioxide, safety standards and why GWP values change, with handy links

to relevant web sites if you need more detailed information. A summary of the most critical legislation provides updates on F Gas regulations, Energy Savings Opportunity Scheme (ESOS Regulations), Energy Audits, Energy Performance and Building Regulations. There is also a news and press section for visitors to keep abreast of the sector’s latest developments and users can register to receive regular updates to the ACRIB site.

What is ACRIB?

For anyone who may not have heard of ACRIB, it was founded in 1995 as an umbrella body for the key trade associations and institutions active in the refrigeration, air conditioning and heat pump sectors. Members represent trade associations made up of end users, manufacturers, contractors and professional institutions cover refrigeration, air conditioning and heat pumps in the stationary and transport sectors.

A DAY IN THE LIFE OF A GREEN POINT MANAGER Will Pribyl is Business Manager for Green Point UK, the service organisation of compressor manufacturer BITZER, which maintains, overhauls and repairs BITZER compressors as well as those of other manufacturers.

What “makes” your day as a Green Point manager?

Seeing an order come in from a new customer. Our retention rate is high, due to the quality of service and the end result we provide, so it can mean much more than just one compressor sale.

How much time do you spend on the shop-floor, talking to staff and keeping in touch with the hands-on part of the project progress?

It varies, but 40% is probably about right.

It’s a key aspect of the job, keeping in touch with projects as they progress and ensuring clear communication throughout the process between all parties, to ensure we deliver for our customers.

Is there such a thing as a typical day for you?

Every day is different, which is one of the attractions and challenges of the job. As with most companies, there is a daily business routine, but we often have unexpected and sometimes surprising requests, which keeps things constantly interesting and unpredictable.

What is normally the first thing you do business-wise in the morning?

Go around and say good morning to the team, and have a brief chat about the day ahead with Emma, my colleague and key anchor person.

What are the three items currently at the top of your To Do list for this week?

Finalise terms and conditions with a global supplier to forward upcoming sales orders; coordinate the necessary marketing

information with Bitzer headquarters for the UK version of the new global website; and start the process for hiring a sales person for the UK.

What is the most satisfying aspect of your job?

Getting positive feedback from customers about our compressors and our services.

At the end of the day, it doesn’t matter how well we think we have done; what

Looking ahead, what are your strategic priorities for the year ahead?

Sales, sales and more sales! Amid all the variety and the daily routine, it is the constant drive that underpins everything we do. It’s why we are initiating the recruitment drive, and why it’s high on my list of priorities.

How often do you travel?

Honestly, not enough. Again, it’s one of the reasons we have taken the decision to employ an additional sales person in 2017, to ensure we raise the profile and see key existing customers and potential customers, so we maintain momentum to build the business.

matters is keeping our promise, on both time and quality, to enable our customer to deliver in turn for their customer. To hear we have helped save the day, helped clinch an order or secured a valuable relationship for a customer, is obviously immensely gratifying.

What is the most challenging?

For me, time management. Being responsible for most aspects of the business means that you have to use your time carefully. It is very easy to get drawn into the operational side of things at the expense of the strategic.

I guess it is an issue for all business managers. You need to keep a clear eye on and a �rm grasp of both, and move forward on both levels in tandem.

How do you lead and inspire your team concerning the central Green Point brand values and philosophy?

I hope by example, in everything we do and in the way we behave, towards customers and each other. We’re providing a local o�ering of a global service. Being the only global remanufacturer in the UK means upholding Bitzer’s exceptional standards of service and approach. It distinguishes us from the competition, and is a gold standard that permeates everything we do.

Do you have a suggestions box?

I encourage ‘continuous improvement’ and an ‘open door’ approach. Colleagues are encouraged to come forward with new ideas at any time. This has already resulted in an overall increase in the e�ciency of our remanufacturing process, and a better understanding of our customers’ needs – which feed into further business success.

How important is a good communication with Bitzer HQ in Germany?

Are you currently engaged in any development projects?

As mentioned, Green Point is a global business, owned by Bitzer. Being part of this strong and international network o�ers many advantages and resources, channelled through Bitzer headquarters.

Our excellent relationship with colleagues in Europe and elsewhere on a daily basis only furthers and strengthens the Green Point business here in the UK.

On average, how many times a week would you talk to colleagues there?

Yes, our UK Green Point website has been coming to fruition over recent months, and will be constantly developed. We are always looking for new and better ways to connect to our current customers and to new customers as well.

Do you have a personal motto or slogan that sums up your approach to work?

We talk on a daily basis. Our range of products and services, as well as the international Green Point network, provide huge potential for sharing information and supporting one another, to the bene�t of our customers.

I actually do: We will always o�er a solution to our customers. We never simply say ‘No’.

Do you ever make the drinks in the office?

Absolutely, if Emma made all the co�ee we get through at Green Point, she wouldn’t have time to do her job!

‘WE’RE BEING ASKED TO SUPPLY

SIGNIFICANTLY MORE UNITS

FOR BOTH COOLING AND HEATING’

M

ulti split air conditioning equipment has been used to provide the primary heating source as well as comfort cooling in the refurbishment of a Victorian detached home in the Home Counties.

The project is a joint venture between air conditioning manufacturer LG, M3R Climate, an air conditioning specialist from Milton Keynes, and air conditioning contractors KV Cooling, from Stanmore.

And Ryan Kontoh from M3R Climate says the heating requirement of the project re�ects a growing trend.

As a result of a range of refurbishment activities, the home stands out from surrounding houses on the road close to the M25, with the owner keen to incorporate a wide range of renewable and energy saving elements.

Less energy

The property features triple glazed window units, air conditioning with a traditional condensing boiler ‘back up’ heating system, under�oor heating downstairs, high levels of insulation and solar panels on the south facing roof.

The homeowner says the LG Artcool gallery units heat and cool brilliantly and use less energy than a boiler, providing rapid response from the remote controls that come with the units. Two multi split condensers [model ref: MU4M25.U43 and MU3M19.UE3] are wall mounted outside the property each connected to two Artcool gallery units indoors – two in the lounge and two upstairs – one each in the master bedroom and in the children’s bedroom. The upstairs Artcool units can deliver a cooling capacity of 2.64 kW and a heating capacity of 2.93kW, while the downstairs units can deliver 3.52kW of cooling and 3.87kW of heating.

“We’re being asked to supply signi�cantly more of these units to provide primary heating and summer

There is an expectation that the equipment will be top of the range and it is. They are genuinely impressed with their purchase and decision.”

admit it was pretty impressive,” said Kish.

“The performance statistics are good and the feedback from the customer is very encouraging – we like to have happy customers and that’s what this system has given us in this case.” www.lg.com/business HVAC.marketing@lge.com Yovan Popov and Kish Vaghela from KV Cooling

Impressive performance

“It’s certainly something we are seeing across the country,” says Andrew Slater, LG’s Technical and Research Senior Manager. “There is a growing awareness of the �exibility of our equipment and a willingness to see what we sell as air conditioning as a heating system that has the capability to provide comfort cooling in the summer months. It’s just a case of interpretation.”

KV Cooling’s Managing Director Kish Vaghela and Senior Engineer Yovan Popov were both impressed by the ease of installation and performance of the LG equipment. “We haven’t installed a lot of LG equipment before but have to

CONCEALED,COMPACT

AND WITHOUT COMPROMISE Martin Passingham, Product Manager for DX at Daikin UK, discusses how modern trends in the retail and light commercial sectors demand a discreet, compact, cost-effective and high-performance air conditioning solution.

Martin Passingham

alancing the requirements of customer or sta� comfort against the aesthetic and logistical realities of installing an air conditioning unit can be a major dilemma for many businesses. This is especially true in urban areas where outdoor space is restricted.

The condenser element of air conditioning systems can be relatively bulky and thus is most commonly installed

on a roof, basement or in a side alley.

However, this may not be feasible in densely populated areas where buildings routinely serve a mixture of commercial, residential, leisure and social purposes. Consequently, roof space may be occupied by penthouse apartments, basement space utilised by car parking and strict planning permissions may prohibit installing a system in a side alley.

While available building service space shrinks, the focus on employee wellbeing is growing. Shifting cultural attitudes brings with it more expectation from workers when it comes to a workplace’s physical environment. There is also a growing trend among progressive employers to place more credence on the day-to-day experience of their employees. Creating stimulating, inspiring and dynamic workspaces is thought to have a positive e�ect on both morale and productivity, and is now viewed as a priority by many organisations.

Comfortable

Aesthetic and atmospheric considerations are also of paramount importance in the retail and light commercial sectors. Increasingly, a signi�cant amount of thought, planning and research goes into every design decision and its a�ect on consumer behaviour. Retailers want to present their o�erings in the most eye-catching and appealing manner. This often means the incorporation of sleek and minimal design, where elements such as piping, plumbing and air conditioning are hidden from view. In addition, restaurants and bars want to create a comfortable and ambient atmosphere where any potential noise from a building’s services is kept to a minimum.

However, maintaining a comfortable temperature is always a key stipulation for businesses of all kind, so it is imperative that installers provide their customers with energy e�cient and cost e�ective air conditioning solutions that can meet all their needs.

Keeping pace with the changing demands of evolving built-environment trends, the most forward thinking air conditioning manufacturers have developed solutions that can service any conceivable building requirement.

Invisible

The Daikin VRV I-series offers ‘invisible’ air conditioning

For example, the Daikin VRV i-series, which is now available in an 8hp version, is speci�cally designed for applications where outdoor air conditioning units are not possible due to space limitations, architectural considerations or planning constraints.

Overcoming the issue of outdoor space, the innovatively compact unit is mounted entirely indoors with only a grille visible outside. Furthermore, by

“

The interior unit is compact and can be discreetly positioned

using decorative elements of a building’s façade to hide the grilles, installation can be rendered completely invisible from street level.

Speaking of this unique design element in reference to a recent installation of the Daikin VRV i-series at Leon restaurant in London, Gary Piper, HVAC Manager at Synecore, said: “To be able to install such a discreet and highly e�cient air conditioning system will hugely bene�t many high street retailers across the UK, where sourcing outside space for a condenser can be challenging. At Leon Fenchurch Street, you will not visibly see any sign of the air conditioning system on the exterior of the building.”

Cost-effective

The heat exchanger of the VRV i series is integrated within the ceiling, with an outside vent. Its V-shaped heat exchanger and high performance fan combination o�ers higher air �ow and

static pressure, resulting in higher e�ciencies compared to a standard outdoor unit installed indoors. The compressor element is compact and can be installed indoors, within an o�ce, storage room, kitchen or technical area.

In the case of Leon restaurant, the compressor was installed completely out of sight in a cupboard.

The Daikin VRV i-series also facilitates faster and more costeffective installation as the components can be transported in a simple and straightforward manner.

This means premises can be opened quicker as building permits are easier to

obtain and building regulations are easier comply with.

As commercial and retail space becomes an increasingly scarce commodity and the comfort of employees, customers and end-users becomes evermore important, installers face new challenges to meet customer requirements. However, by including the latest systems within their portfolio, installers can reap the bene�ts of hassle free installations, whilst o�ering their clients an invisible, cost e�ective and high-performance air conditioning solution. www.daikin.co.uk

KEEPING IT COOL

IN THE WORKPLACE Specialist contractor and installer Heritage Heating and Cooling outlines the importance of air conditioning for business.

A

s business owners, the wellbeing of employees is of the utmost importance to ensure that they are comfortable in their working environment. In turn, it will enable them to be more productive and add value to any company during the height of summer.

The climate of an o�ce, building, or store can change very quickly and the absence of a fully functioning air conditioning system can see stress rise and productivity drop o�.

Being too hot in a workplace may result in employees su�ering from dizziness, fainting, and even heat cramps. The Chartered Institute of Building Services Engineers recommends the following temperatures for di�erent working areas; ₀ Heavy work in factories – 13 °c ₀ Light work in factories – 16°c ₀ Hospital wards and shops – 18°c ₀ O�ces and Dining Rooms – 20°c

So, what other factors make air conditioning so important for business during this time of year?

Improved concentration

Not only will employees work harder with air conditioning, they will work smarter.

It has been proven that those working in o�ces without air conditioning make more mistakes, as their energy and concentration levels decrease. Not only this, but the temperature is the number one cause of o�ce arguments. Being too hot makes individuals more irritable, and the performance of the business could decrease rapidly if it’s �lled with people who are feeling restless.

Having air conditioning increases employee concentration spans, making it easier to solve complex problems. You want your employees to be sharp and on task while at work, and this can prove di�cult when they are overheated.

Restriction of productivity

80% of o�ce workers complain about the temperature of their workplace, and an unsatis�ed worker is unlikely to be a productive one. 92% of workers lose up to an hour per day due to an uncomfortable o�ce temperature and 6% spend over an hour not working each day for this reason.

Overall, 2% of o�ce hours are wasted due to temperature alone, which could cost the UK economy more than £13 billion annually. The time that employees are wasting due to soaring temperatures are costing businesses money. Air

conditioners keep employees working harder, saving money and making the business more e�cient.

Better for customers

If you own a store, customers won’t spend long in your shop if the temperature is too hot throughout the summer. Similarly, for o�ces, clients won’t enjoy being shown around a building that is sti�ing.

Air conditioning could be a big draw for people walking past and result in increased foot tra�c as potential customers look for a way to stay cool. Don’t miss out on what could be a lucrative business opportunity by ensuring that you have properly working and maintained air conditioning throughout the summer.

Energy efficient

Air conditioning technology is constantly evolving and systems of all types, from simple split systems, to larger heat recovery VRF systems, are becoming more e�cient. They are able to e�ciently cool and heat a building, providing a constant and comfortable temperature. This could minimise energy use, reduce utility costs, and reduce the carbon footprint of a business.

Controllable comfort

Air conditioners provide high levels of comfort, as the systems respond rapidly to changes in temperature.

Sophisticated systems are able to recover heat from warmer areas and redistribute to cooler areas, making them extremely e�cient.

Protects critical business equipment

As modern workplaces are packed with technology that generates heat, the unwanted heat needs to be removed from the environment to ensure that delicate equipment remains operational.

Air conditioners take heat and humidity out of the surrounding atmosphere, dispersing that energy elsewhere where it’s needed, ensuring business-critical equipment is safe.

Improves air quality

Busy o�ces can be a breeding ground for coughs and colds. Air conditioning �lters purify the air, reducing the number of bacteria and dust particles, odours, and potential allergens. Employees and customers bene�t from clean, �ltered air, this is particularly important for those who su�er from allergies or respiratory problems.

Reduces humidity

No employee likes to feel hot and sticky at work and increased humidity can make an environment feel hotter than it actually is. This can be combatted through installing an air conditioning system, as it will remove excess moisture from the air to eliminate that uncomfortable feeling.

Air conditioners employ the

23

same operating principles and basic components as the home refrigerator; using heat from the interior of the workplace and transferring it to the outside environment.

Air conditioning in the workplace contributes towards the health and safety regulations put in place to lower the risk of any injuries or health problems. Furthermore, by removing the humidity and excess contaminants in the air, it provides a feeling of freshness without causing a draught and leads to higher levels of productivity throughout any business.

Air conditioning does much more than provide great comfort within a workplace in a cost-e�ective manner; it has a knock-on e�ect that will assist the longterm growth strategy of any business. www.heritageheatingandcooling.co.uk

AIR CONDITIONING RATES

HIGHLY AMONG HOME BUYERS

“

Cooling in the home has been named one of the UK’s most desired property features, according to figures from property website sellingup.com.

I

n a consumer survey of more than 2000 people, 57% said that air conditioning �tted in living and sleeping spaces would make a property more desirable, with just 7% saying otherwise.

Air conditioning has not, historically, been a major consideration for UK residents, but a wealth of evidence suggests this is set to change. Research from the University of California suggests that 700 million air conditioning units will be installed worldwide by 2030, rising to 1.6 billion by 2050, with the UK playing a signi�cant role in this uptake.

Brits have become accustomed to air conditioning at work, in their cars, whilst shopping and, of course, while on holiday, so it’s no surprise many are taken with the idea of temperature control at home, too. However, there are a number of other factors pushing its popularity.

Temperatures are rising around the globe, and the UK is no exception.

According to the Met O�ce, the UK can expect increasingly milder winters and warmer summers for the next �ve years, with heatwaves becoming the norm across Europe by the 2040s.

Consumers will no doubt turn to domestic air conditioning, particularly in sleeping

BRITS HAVE BECOME ACCUSTOMED TO AIR CONDITIONING AT WORK, IN THEIR CARS, WHILE SHOPPING AND ON HOLIDAY”

areas, for the relief from sti�ing weather that open windows and desk fans can’t achieve.

The in�ux of foreign property buyers to the UK will also play a part in the increasing popularity of air conditioning.

The number of overseas buyers looking for a home in the UK has jumped since Brexit, with the pound’s fall against the dollar sparking a surge of interest because of the discounts on o�er. Air conditioning is a feature which comes as standard in most other western and developed countries, and is therefore likely to be a consideration for overseas purchasers when it comes to renovations and investments.

Weather patterns and economy aside, however, the UK’s uptake in air conditioning can also be attributed to a growing national interest in home environment.

More onus than ever before has been put on interior design and smart technology, and as the survey indicates, top-line features such as under�oor heating and remotely-controlled curtains and blinds rate highly with would-be buyers (with 65% and 36% respectively claiming they make a property more desirable). Such features make a home more comfortable without intruding on often carefully-considered aesthetics and design, a bene�t also o�ered by air conditioning.

HOW DO YOU KNOW WHEN YOU HAVE A CLEAN FAN COIL? (Here’s a clue: the answer isn’t as always straightforward as you might think)

R

egular cleaning and maintenance of ACR units not only helps to prolong the life of the units, but helps your bottom line by reducing power consumption — as well as your carbon footprint.

Katrina Palmer explains the benefits of VerteX in the new video from Advanced Engineering

But when it comes to cleaning the coils, are you actually doing what’s best or are you in fact causing yourself more issues in the long run?

The problem — which won’t come as a surprise — is the dirt itself. Dirt comes in many di�erent forms: grease, fats, organic debris, rust, scale, inorganic salts and more, and this is the nub of the problem.

Di�erent types of dirt can be at wildly di�erent places along the pH acid–alkali spectrum and need di�erent pH cleaners to combat them, so �nding the correct cleaner is paramount.

Extreme build-up

You can typically categorise dirt into one of four types depending on where it sits on the pH scale and the oil–salt scale.

Fundamentally, you have acidic oils, basic oils, basic salts, and acid salts.

HVAC cleaning products tend to skew sharply towards one end of the pH scale or the other to go in strong on particular dirt types. These products can be perfectly �ne to use from time to time, when there may be an extreme build-up which needs shifting.

However, if you �nd yourself employing these harsh chemicals for regular maintenance, it may come at a high cost. While application of these chemicals may make them appear shiny and new and give the understandable impression of a job well done, they can strip the aluminium coils of their oxide layer, leaving them vulnerable to further dissolution. This will result in coils with a reduced mass and a signi�cant reduction in energy e�ciency.

Effective cleaning

As a response to this industry-wide problem, Advanced Engineering spent three years developing a product which could provide e�ective coil cleaning – across all four types of dirt – on a regular basis… without the detrimental side-e�ects.

The result was VerteX: a full-spectrum pH-neutral aqueous -based cleaner speci�cally designed for condensers and evaporators.

Unique within the HVAC market, the formulation of VerteX means it is able to adapt its pH value to better deal with dirt it comes into contact with… without damaging or etching coils.

VerteX has a low VOC (volatile organic compound). What’s more, VerteX has odour-neutralising properties, non-carcinogenic and SUPERenvironmentally-friendly (this means that every ingredient in VerteX is 100% nonbioaccumulative, and that the chemistry framework is based on organic salts).

This ensures it is suitable for use, even during daytime shifts.

So, how clean are your coils?

If the answer is too clean then it could be time to switch your maintenance regime.

For more information on VerteX, suppliers and engineers can call Advanced Engineering on 01256 460300 or visit advancedengineering.co.uk.

IGNORING THE W WILL SPELL TROUBLE A-Gas Managing Director John Ormerod explains why warnings about refrigerant shortages could become reality if action is not taken by everyone.

John Ormerod

From 2020 R404A will be banned from use in commercial refrigeration and so it is bizarre that contractors are still opting for it in new installations. Along with other commentators in the industry, I have warned about the dangers of adopting this ‘head in the sand’ attitude.

Balanced market

T

Let’s be clear that a 37% decrease in supplies is a big cut and those ignoring these warnings are only storing up trouble for the future. This is a 37%

carbon dioxide equivalent reduction of all refrigerants placed on the market and as R404A has the highest carbon dioxide rating of them all this will have a disproportionate e�ect on how the quota is consumed.

A 37% cut from its CO2 base means that if we want to continue to buy the same tonnage of refrigerant as we currently do, then we need to make an enormous shift to lower GWP products in order to keep the market balanced – otherwise we run the riskthat we use

he shift towards the industry buying low GWP refrigerants is gathering pace as 2018 nears and a 37% reduction in the quota for the production of virgin gases becomes a reality. Prices of refrigerants have risen throughout the year and now a major cut in supplies is only �ve months away the market is bracing itself for further upheaval.

The phase-down cli� in 2018, as described by industry observers, has sharpened some minds but has dulled others. In the former, camp Honeywell has announced that it will stop selling R404A and R507 and this has given a clear indication to the market that change is on the way.

In simple terms the 37% reduction means that an enormous chunk of gas supply to the market will disappear next year. If the industry continues with the current mix of products it is buying and installing then we will de�nitely have shortages of gas in 2018. This cut in high GWP refrigerant is going to hit hard R404A supplies – the most widely used gas in commercial refrigeration.

E WARNINGS

E IN THE FUTURE

“

up all the quota selling R404A and there won’t be any left for other refrigerants.

Honeywell’s announcement has been described by some observers as a brave decision but to my mind this points to the reality of the situation. Honeywell have done their homework on the amount of quota they will have available and quickly �gured out that combined with the 37% cut, if they carry on selling R404A at the current rate it is probably going to use up more than half of their overall quota.

In this scenario there will not be the availability of other refrigerants to make the transition away from high GWP gases like R404A. By taking this decision it means that Honeywell can guarantee that they will have su�cient volumes of the next generation low GWP gases available.

Real risk

Contractors and users of refrigeration equipment simply cannot wait until next year before they make the switch to the alternatives. They need an exit plan in place for R404A now.

If installers and end users do not change to low GWP options there is a real risk that there will not be enough of these alternatives to go round to service the market. If as an industry we carry on buying large quantities of R404A at the rate we are doing, the fall from this cli� will be a steep one.

One of the quirks of the quota system is that attaching these reductions to a CO2 equivalent tonnage allows the market to grow if people make the change to low GWP products. But if users fail to switch – and in some cases up to now this has been the experience we’ve come across – the quota systems will

FROM 2020 R404A WILL BE BANNED FROM USE IN COMMERCIAL REFRIGERATION AND SO IT IS BIZARRE THAT CONTRACTORS ARE STILL OPTING FOR IT IN NEW INSTALLATIONS. ALONG WITH OTHER COMMENTATORS IN THE INDUSTRY, I HAVE WARNED ABOUT THE DANGERS OF ADOPTING THIS ‘HEAD IN THE SAND’ ATTITUDE”

have the opposite e�ect on the market of cutting supplies which in turn will lead to shortages.

To some extent if you let the market run its course within the F-Gas reduction programme you can easily run into these kind of problems. That’s why the message that everyone in the industry should take on board is to make the switch now before it’s too late. Sales of R404A have been declining over the last few years but in some respects not fast enough to demonstrate the fact that everybody has understood the challenge of 2018.

Price rises

I can only think that installers and speci�ers who are still recommending R404A for new equipment are doing so because it is an easy decision.

To be fair to them they are probably

used to working with the gas and �nd the switch unsettling.

But if they are unsure about what to do, help is there from their refrigerant supplier who will be happy to advise on the right choice for the job. That aside, price rises driven by supply and demand will probably be the �rst thing that will in�uence the minds of the latecomers to the party.

The good news is that the supermarkets have understood the issue because they have a large amount of refrigeration equipment to run and maintain. The recent announcement about the Tesco conversion programme illustrates this and generally speaking the major store chains have grabbed the bull by the horns. It is now up to everyone in the industry to follow suit. www.agas.com

DON’T LET FAKE OILS

COMPROMISE CHILLER PERFORMANCE

The increase in of sub-standard counterfeit oils on the market threatens chiller performance and, in the worst cases, can result in total mechanical breakdown. ACR Journal looks at the issue and what one leading manufacturer is doing to protect its customers.

O

il is a critical component in refrigeration and air conditioning systems.

Compressor designers and system manufacturers go to great lengths to ensure effective oil management within plant, because performance and reliability depend on it.

Similarly, the precise properties and formula of lubricants used in cooling systems have a big impact on performance, efficiency and reliability. The phrase “liquid engineering” sums up the importance of oil in the overall system, and encapsulates the precision required in its formulation for a particular application.

The role of refrigeration lubricants in protecting wear surfaces, maintaining leak-tightness, ensuring long-life and, not least, enabling proper performance and efficient operation, is crucial. Lubricants also play a vital role reducing corrosion, which can quickly result in serious internal damage and / or mechanical breakdown.

Sensitivity

Due to the sensitivity of refrigeration systems to contamination and the mechanical and thermodynamic stresses that lubricants are subjected to in working systems, the precise formula and properties of oils used in refrigeration is particularly important.

This is why the recent appearance of sub-standard and counterfeit refrigeration oils on the market is of such concern. A contaminated or out-ofspecification oil can break a compressor, or result in poor performance, reliability and reduced working life.

Responding to the problem, leading chiller manufacturer Johnson Controls recently issued a global initiative to alert installers and end users about the risks of using counterfeit oils in plant.

Alpesh Trivedi

Alpesh Trivedi, Product Manager, Johnson Controls IR & HVAC parts in Europe, says: “Low grade counterfeit oils are increasingly common in some markets. They often have inferior ingredients and may contain contaminants such as harmful additives, and generally do not adhere to the tight specification laid down by the original equipment manufacturer.

“This can result in chemical breakdown within a chiller, resulting in acid build up which can have devastating consequences for chiller performance. In the most extreme cases, it can lead to total mechanical breakdown. If this happens, the small cost savings from using counterfeit oils are completely eclipsed by the cost of repairing or even replacing the chiller, not to mention the inconvenience for building owners or loss of productivity in process applications.”

To protect customers from the risks of counterfeit oils, Johnson Controls has introduced a range of uniquely branded and authenticated lubricants, YORK PureOil, guaranteed to meet the specifications for particular chillers and mechanical cooling applications.

The gallon containers carry a YORK seal of authenticity, to reassure contractors

and end users, and deter those seeking to pass off inferior products as genuine components supplied by the original equipment manufacturer.

The lubricants contain no damaging additives, have a high flash point, and are resistant to high temperature breakdown.

They also have a guaranteed low moisture content, and low pour points to discourage oil congealing in condensers and evaporators.

Johnson Controls recommends that oil in working chillers should be analysed on a regular basis to assess the internal mechanical condition of the plant. “In a similar way to a blood test in medicine, oil analysis can give vital clues to the way the system is operating and if any potential problems are brewing,” says Alpesh Trivedi.

Reassurance

“The company sees this as a two-stage approach to protection. Contractors should make sure they use only authentic lubricants in equipment in the first place; and, then, throughout the life cycle, carry out periodic tests to ensure everything is operating normally.

“Continuing the medical analogy, blood transfusions require scrupulous matching of blood type between donor and patient.

We advocate taking a similar level of care with the use of refrigeration oils. Given the potential harm that can be done to the system by sub-standard or contaminated oil, it is part of the contractor’s duty of care to their customer to ensure that the correct lubricants are used.

“The launch of authenticated York PureOil as a global product gives reassurance to contractors that the lubricant is produced to the highest specification and will perform exactly as required”

CAREER DEVELOPMENT FOR WOMEN IN RACHP

T

he Institute of Refrigeration held a career development workshop for Women in RACHP to coincide with International Women in Engineering Day 2017.

The two-part networking session, hosted by training and consultancy specialists Cool Concerns in Tewkesbury, began with a practical event enabling non-technical sta� to gain a hands-on understanding of refrigerant handling and brazing. This was followed by an interactive career development workshop with handy tips on career management and planning.

The workshop received excellent support from the industry with many organisations becoming sponsors and sending delegates to the sold-out event. HRP, Space Engineering, Carbon Data Resources, Bitzer UK, Fujitsu, Star Refrigeration, Adande Refrigeration and Daikin UK were all represented.

Miriam Rodway, CEO, Institute of Refrigeration, said: “Our industry is currently facing a skills shortage and it’s never been more important to encourage

women to choose a career in refrigeration and air conditioning engineering.”

According to the Women’s Engineering Society, there is now very little gender di�erence in take-up and achievement in core Science, Technology, Engineering and Maths (STEM) GCSE subjects, yet only 9% of the engineering workforce is female, meaning that there is a large skill pool currently untapped.

Great idea

Samantha Buckell, PA to the Managing Director at Bitzer UK, said: “I really enjoyed having the opportunity to take part in a practical session as this has given me a better understanding of how our industry works and I’ve made some fantastic contacts working in the various RACHP sectors.”

Another participant, Catarina Marques, Engineering Manager at Adande Refrigeration, said: “I felt it was a great idea to have a two-part day as technical knowledge and career planning are both incremental parts of a successful career path.”

Attending the event were: Elizabeth Dunlop, Kat Hill, Sam Parris, Alice Thornton and Hayley Webb (all HRP), Emily Fagence and Cat Whiting (both Space Engineering), Carole Bond (Carbon Data Resources), Sam Buckell (Bitzer UK), Kelly Bullivant (Fujitsu), Fern Dane (Star Refrigeration), Catarina Marques (Adande Refrigeration), Karen Perry (Daikin UK), Lisa Waters (IOR) and Imogen Soper, along with Jane Gartshore, Stephen Benton and Alan Snelling from Cool Concerns.

The IOR is planning further events for Women in RACHP and has an active RACHP network with a LinkedIn Group that is open for all to join.

DEALING WITH HUMIDITY

ISSUES AT SOURCE Ed Whinyates of Stonegrove Refrigeration and Simon Mills of dehum examine the issues that moisture can cause in cold storage facilities and the most efficient and cost effective solutions to resolve this.

H

igh humidity can often play havoc within many manufacturing processes.

Unfortunately, it is hard to detect and often overlooked as the reason why production is being a�ected or even halted.

The psychrometrics¹ involved in understanding how products and processes can be improved by controlling the relative humidity (RH%)² and dew point (dpt)³ levels can be complicated.

Creating the correct environment can improve production e�ciency, reduce downtime, eliminate bottlenecks, ensure consistent production rates and improve Health & Safety standards.

Chilled food distribution centres and commercial cold stores present their own unique issues to deal with. Anywhere that reduced temperatures are required BEFORE: A door in a cold store with a build-up of ice

to protect or store chilled or frozen products, has the potential for serious issues in relation to: ₀ Ice and snow inside the cold store ₀ Risk of falling ice ₀ Frost shock on product ₀ Failure of door mechanisms ₀ Increased running costs of refrigeration plant ₀ Increased defrost cycles ₀ Health & Safety

Why does moisture develop?

We have all seen snow and ice on product, ceilings and internal evaporators within cold storage facilities. This is created when store openings allow moist warmer air in adjacent areas (marshalling or ambient stores, for example).

Each time a door is opened to a cool or cold area, air and moisture enter from AFTER: The door (minus ice) once a dehumidification system has been installed

any adjoining untreated source. This air is then rapidly cooled and the moisture contained within it is deposited on the coldest surfaces. Depending on the temperature in the room, this moisture will then appear as condensation or frost.

This can build up and create Health & Safety issues for personnel and for the transportation of goods.

How can moisture be prevented?

The use of a desiccant dehumidi�er⁴ in these instances deals with the moisture at source and the units themselves create a low dew point in the air in any neighbouring areas. By removing the moisture at source, the dew point can be reduced dramatically to a point where there is simply not enough moisture to condense on the cold surfaces. This means that when the doors into the cold areas are opened, there is insu�cient moisture to create condensation or snow/ ice within the facility.

Simple dew point control can be incorporated into the control software in the units to ensure that only the minimum amount of energy is consumed to create the condition needed to overcome the risk.

Removal of moisture in this way also has the added bene�t (for the cooling plant) of removing the latent elements of the load from the air, allowing evaporators to run drier, with fewer defrosts and improved plant e�ciency.

What should you do next?

Speak to a specialist in this �eld and arrange a site visit, so your facility can be assessed. dehum has a range of dedicated cold store machines which have been developed to deal with the rigours of installations in these types of hostile environments and e�ectively manage the humidity within cold storage.

¹ Psychrometrics – the science behind the behaviour of air. Used to calculate how the various conditions that interact with air can be modified, to produce the ideal conditions required by a multitude of production processes. ² Relative humidity (RH%) – measured as a percentage of the amount of water vapour in the air relative to the amount of water the air can hold at saturation. ³Dew point (dpt) – measured in °c dpt, it is the temperature of the air at saturation. The point at which the air can no longer hold the moisture; 100%RH is reached and water starts to condense. ⁴ Desiccant dehumidifier – a specific type of dehumidifier used to extract moisture from the air.

A desiccant dehumidifier uses a slowly rotating wheel which holds the desiccant material. It is particularly effective, even when used in extreme temperatures.

DAIKIN ON SITE HELPING

HOSPITAL PROVIDE CRITICAL CARE

How a new remote monitoring system is helping England’s first purpose-built emergency hospital maintain the highest levels of treatments for patients.

A

specialist hospital in Northumbria is using the Daikin on Site remote monitoring system to help make sure its operating theatres and wards are available to care for seriously ill and injured patients across the region.

DoS has been developed by the Daikin Applied (UK) (DAPUK) applied chiller engineering design team, working closely with Daikin Applied Service (DAPS UK) to provide a browser-based real-time view of a site’s chiller and AHU operation.

Launched in February, the system is proving successful with end-users and facility management teams, offering greater levels of service through a proactive approach. DoS has been installed at a number of sites throughout the UK and Europe, including Northumbria Specialist Emergency Care Hospital in Cramlington.

Opened in 2015, the hospital provides specialist emergency cover for seriously ill and injured patients from across Northumberland and Tyneside. It is England’s first purpose-built specialist emergency care hospital, with emergency consultants on site 24 hours a day, seven days a week.

Real-time information

The building has three Daikin Applied 1150kW air cooled inverter screw chillers to cope with the demand of the hospital.

Due to the critical nature of the building and the need for the water chillers to be available to service operating theatres and wards 24 /7, the hospital trust entered into a maintenance contract with Daikin Applied Service and response times to any potential problems or failures was key to the trust’s decision making. DAPS were able to offer DoS as part the contract, which brought a new dimension in remote monitoring of the chillers.

Unlike other remote monitoring

solutions, a DoS enhanced chiller (standard feature available on all current generation chillers) is equipped with a LAN address em bedded in the controller, once activated with an internet connection the chiller connects to the DoS cloud and begins to send real-time information which is then stored in the cloud.

This information can be retrieved by a DAPS technician, remotely enabling review of historical trends or issues. Data logging of real time operating parameters can be done on the fly and this information can be exported into an excel sheet for analysis.

Real-time intervention can also be made.

In the event of an alarm on the chiller an email is sent to the DAPS service team and the unit can then be accessed by a fully trained technician. The technician can assess the problem, make any resets necessary or adjustments to the controls as required. Alternately they can use the real time history, look at the operating

condition of the unit prior to a fault or an alarm occurring and assess what is required to bring the unit back into full operation. DAPS can then dispatch a technician to site with the right parts to give a first fix and bring a failed unit online quickly.

Exciting development

For the trust this means that response times is now measured in minutes not hours, in fact in most cases when a fault occurs a DAPS technician is already looking at the problem before the customer is aware of an issue. This was put to the test in a recent incident, when a problem occurred on the chiller installation over the holiday period affecting all three units. DAPS were able to identify the cause of the issue, using the real time data and historical data stored in the cloud. With this information, it was possible within a few minutes for

the technician to make adjustments to the unit controls to overcome the issue while leaving the units in safe operating condition and advise the client the likely cause of the external problem all without an engineer stepping foot on site.

Daikin Applied Service’s National Service Manager Barry Coe said: “Daikin on Site is the most exciting new development in the chiller servicing industry in the last 25 years. It enables us as a service provider to give our customers even faster reaction times, real time advice on improving the system efficiency and prevent issues before they occur.

We live in a technological advancing world with ever increasing demands and Daikin on Site will help us to exceed current client expectations taking chiller servicing to new heights.”

Profile monitoring

The platform also has multiple user roles which can enhance the overall performance of the system. Users can create personalised dashboards so that the customer only sees what is important to their installation and the system becomes

second nature in assisting the running an efficient chiller installation onsite.

Historical working condition data and alarm history is available for the whole life cycle of the chiller operation at a single click and automated reporting setup is possible to provide tailored reporting for when and where needed. Access to multiple site installations through one web portal is no issue for the DoS solution as the web platform allows users to set up their own site profiles and they can view their own installations anywhere.

DoS allows remote monitoring and operation of the chiller equipment both in real time and based on historical trends. This can include energy usage via an energy meter but also includes all operating parameters of the compressor, fans, refrigeration circuits and thermal load. The installation profile monitoring and analysis of the information can result energy saving proposals including Variable Frequency Drives (VFD) for compressors, condenser fan upgrades or improved controls. www.daikinapplied.uk

₀ Energy efficiency – up to 20% lower energy cost when unit is controlled and working in an optimised operational envelope, which can only be achieved with real world site working conditions. DoS prevents the risk of uncontrolled and undiscovered energy consumption increase, which may be experienced in case of inadequate system operation. ₀ Remote assistance – allowing for faster reaction and better preparation prior to service engineer site attendance, increasing the uptime of the equipment. ₀

Alarm – any alarms generated by the unit are emailed to the helpdesk 24 /7, leading to less time to resolve the issue.

₀ Breakdown – fault diagnostics can begin before an engineer arrives on site, making sure that the right parts are brought to site. ₀

Life expectancy – interaction with the client and adjustment of the chiller configuration together with the smarter service solution will increase the life of the chiller and also avoid unnecessary equipment stress by incorrect operation.

₀

Expertise – direct insight into the optimum use of equipment, including advice from a Daikin Applied expert.

NEW FCU SELECTION TOOL

SPEEDS UP PROJECTS The sheer number of models and options available for fan coil units can be confusing, even for the initiated.

ACR Journal reports on a new tool by CIAT which promises to speed up selection, and produce fast and accurate project quotes for installers and designers.

D

espite inroads by DX multi-splits and VRF systems in recent years, fan coil units (FCUs) remain an important product category in the UK’s building services industry. Advances in design have dramatically improved FCU efficiency in recent years compared with traditional early systems, which has given them a boost.

The wave of refurbishment of offices and commercial buildings that went up in the building boom of the 1970s and 1980s has also resulted in demand for FCUs, as old systems are replaced with modern, higher performance units.

For those managing such projects, as well installations in new builds, a perennial headache is the number and diversity of fan coil equipment options and designs.

With a myriad of types, models and variants it can be confusing to specify the right tech for a particular project.

Mistakes can be expensive and result in costly delays.

Detailed list

CIAT, a major global manufacturer of FCUs and air handling units, produces six styles of fan coil with up to seven different chassis sizes, and 17 model capacity sizes in each style. In addition, units can be dressed in a number of ways, and come with the option of standard or high efficiency EC fan, and several plenum and valve options, before even getting into the realm of controls.

The possible combinations and permutations of these variants literally run into thousands. While it means there is no project where FCUs cannot be applied, the number of options can be dizzying.

“

To address the problem, CIAT has developed an online selection tool designed to speed up the process and minimise errors in specifying equipment for a project.

It takes installers step-by-step through the selection process, and produces a detailed list they can plug into the project design and costings for their customer. If they win the contract, the installer has an accurate and costed procurement list ready to place.

It enables a contractor or consultant to select a fan coil or range of fan coils, and add them to a basket as they would if shopping online in the normal way. The basket keeps a tally of the accumulating contents, and totals up the number, type and cost of the fan coils added.

The user selects the type of fan coil required, whether ducted, chassis, cassette and so on, and then selects it as a 2-pipe indoor, 4-pipe indoor or 2-pipe with electric heat.

Comprehensive data

Power settings and static pressures can be varied, as required, enabling precise speci�cation of units. FCUs can also be selected on the basis of capacity (kW) or, if there are noise sensitivities on a project, selected on the basis of sound power rating.

The tool shows capacities in terms of cooling (including sensible) and heating, air�ow and noise rating at high fan speed, medium fan speed and low fan speed.

Prices are also shown for all models, variants and sizes.

CIAT floor-standing FCU

THE POSSIBLE PERMUTATIONS RUN INTO THOUSANDS AND THE NUMBER OF OPTIONS CAN BE DIZZYING”

If the user needs comprehensive data on a particular unit, there is a download button under each model reference, providing a full data sheet on the speci�c unit, which can be used in the wider project design and as supporting technical information in a tender.

At the end of the process, the user prints o� a summary and a quote for the selected units. They can also enter their own discount code to deliver a �nal price. To assist with project designs, BIM icons are available for each FCU unit for incorporation into a design scheme.

The selection system is built on an optimised web-based tool, so can be used on a PC, laptop, tablet or smart phone. It is fully automated and removes the manual labour from what has traditionally been an all-too-often complicated and time-consuming task.

High performance

The FCU has long been a workhorse of the industry, but recent innovations are opening up new high performance, high e�ciency options. For example, CIAT has

introduced its EPure air quality �ltration system to its latest generation of fan coils, guaranteeing excellent indoor air quality with 90% of air-borne particles removed within 30mins.

And the company’s Coadis FCU has a visual Coanda-e�ect di�user grill with a 360 deg throw, to prevent draft issues and provide a more comfortable environment for occupants.

Delivery lead times for equipment can be an issue for fast-track projects. The lead time for a base CIAT FCU is reckoned to be around two weeks, which is ahead of the industry norm, but for nonstandard variants involving controls and valves it takes a little longer.

Currently CIAT FCUs are stocked in mainland Europe, but the company is looking to start stocking locally in the UK later this year, enabling a faster turn-around for UK customers.

COOL I NG

COOLING WITH Cooling towers are often responsible for the most widespread and high-profile cases of Legionnaire’s disease. While chemical dosing is essential in keeping cooling towers clean, inefficient use can cause other issues such as corrosion.

Steven Booth, Associate Director for Guardian Water Treatment, explains how best practice maintenance and construction can improve hygiene, therefore reducing the need for excessive dosing.

Excessive use of chemicals can result in corrosion

W

e are all aware of the damage a Legionnaire’s disease outbreak can cause to human health and a business’s reputation. HVAC systems that include too much bacteria are also prone to inefficiency, with essential components clogged and therefore more power required to run the system.

Ensuring water is clean in cooling towers begins with how a tower has been constructed and the water treatment methods chosen at its

inception. Some non-chemical methods, for example, seem to struggle with the demands of controlling the conditions in cooling tower water, particularly as systems age. In Guardian’s view, dosing will always be needed to ensure hygiene - even the most advanced non-chemical technologies need to be installed with a chemical back up. The amount of chemicals used can be greatly reduced, however, if proper maintenance regimes are adhered to. Cutting the overuse of chemical is important to minimise costs and corrosion – excessive bromine, for example, can degrade pipework.

Cooling tower design and layout

If a cooling tower system is designed correctly, e�cient dosing and control can be maintained. Dead legs in pipework and any areas where water is allowed to collect and stagnate will increase the risk of legionella and mean that dosing may be ine�cient. Poor design and badly balanced systems can also lead to water wastage and therefore unnecessary increased chemical usage.

Where issues are flagged up as soon as they occur, they can be dealt with swiftly, preventing major disaster at a later date. The root cause of a problem can also be identified and rectified, rather than just throwing in more chemicals which will only serve to temporarily mask the issue. This information will also steer maintenance practices, which should be based on actual usage, rather than a ‘one-sizefits-all’ approach.

Cooling tower problems

There are various types of cooling tower and evaporative condensers.

In all evaporative cooling systems it is the evaporation of a small amount of water that takes waste heat away from the system – it is a very efficient method of cooling.

Cooling towers are however in essence, massive air scrubbers, and, as such

the most problematic issues will arise from external contaminants entering the water supply, such as pollen or silt.

These contaminants foul surfaces, contributing to conditions in which bacteria can thrive. Apart from silt, scaling, which occurs due to calcium carbonate, can build up also causing system fouling and poor water hygiene.

Bespoke approach

With cooling tower construction and usage varying from site to site, maintenance teams should be trained in a way that is bespoke to their building – a generic understanding of ACoPL8 may not be enough. How this legislation is applied to a particular situation is essential, with classroom learning only falling short of real, practical experience.

Understanding the nuances of a particular cooling tower will improve maintenance regimes and allow for the correct dosage of inhibitors and biocides.

Human safety should of course be

the primary concern, with building managers and installation engineers initially focused on keeping occupants safe by preventing Legionella and other waterborne pathogens. A safe approach can also be an efficient one, however, and by taking a bottom-up view, from construction through to whole-life maintenance, chemical overuse will be reduced and HVAC systems will work more efficiently, saving money in terms of repairs and wasted energy.

Guardian Water Treatment provides cooling tower construction and ongoing water treatment and has recently introduced a new bespoke training programme for cooling tower operatives to teach the requirements of ACoP L8. Training takes place on-site, covering cooling tower operation, weekly testing, as well as site-specific requirements. For more information, visit: www.gwtltd.com

WOME N I N ACR

WOMEN in the

ACR industry

R I N K U

P A T E L

This month, the ACR Journal talks to Rinku Patel, CFD and Mechanical Design Engineer at Airedale International Air Conditioning.

What do you specialise in now?

I specialise in CFD (Computational Fluid Dynamics) – one specific aspect of Mechanical Engineering. CFD is a computational technology that uses numerical methods to solve and analyse fluid flow and temperate related problems.

Within the CFD computer software we create a 3D model of the space or object and visualize the temperature, velocity, pressure and airflow distribution for a given scenario. This type of analysis helps to predict the situation before making huge investment and also helps to find the airflow and temperature-related problems.

What excites/interests you about the industry?

How would you describe your role?

As a CFD and Mechanical Design Engineer I am responsible for creating special mechanical drawings and work instruction sheets for any production order for the manufacturing department. This is so that manufacturing understands exactly how the unit should be built and what the associated components and any special requirement from the customer is. I am also responsible for conducting all CFD analysis on our customers’ data centres to understand the airflow and temperature distribution within their data centre.

Where did you study?

I did my Bachelor of Mechanical Engineering in India and a Masters (MSc) in Mechanical Engineering at Northumbria University, Newcastle, UK

What was your first job?

I was an Internal Sales Support Engineer at Airedale. I think this is a great start for anyone to understand any manufacturing industry, its products, its customers and the company’s position within the market.

What attracted you to the industry?

I was more curious to understand the workings of the mechanical objects surrounding us, which we use in our dayto-day lives, such as refrigerators, car engines etc. From my teenage years I’ve had this curiosity and hence I chose the field of mechanical engineering. During my studies in India I found refrigeration and air conditioning the most interesting as a subject, as I guess this is more closely linked to our day- to-day lives.

I studied a module in Computational Fluid Dynamics during my MSc, and using this technology and knowledge to resolve the industry airflow and temperature problems for customers can be challenging and fun.

How do you see your career developing?

It is developing steadily but I think there is lot to gain yet. I want to gain the CEng title and more hands-on experience of handling projects like the design and development of customers’ bespoke products.

What is the best piece of advice you were ever given?

“Believe in yourself”. This gives me more confidence to face the challenges of the industry.

RISE OF THE Richard Paine, Product Manager for Domestic Heating and Renewables at Daikin UK,discusses the opportunities for the heat pump sector in 2017 and beyond stemming from the updated Renewable Heat Incentive (RHI).

However, the tari� increase is a clear indication of the Government’s support for the renewable heating technology.

Lower costs

F

Richard Paine

ollowing a signi�cant consultation process, in December 2016 the Government announced the proposed changes to the RHI. The anticipated reforms plan to ‘boost the UK product supply chain and installation numbers’ of renewable heating solutions.

Received positively across both the heat pump sector and wider renewable heating sector, Dr Nina Skorupska, Chief Executive at the Renewable Energy Association (REA) stated that the reforms were “an improvement to the earlier consultation” that would “go some way to grow an e�ective renewable heat sector”.

In an e�ort to increase the size of the ‘carrot’ available to property owners, the airsource heat pump tari� has been increased by 35.5% from the current level of 7.51 p/kWh to 10.18 p/kWh. Allowing homeowners to claim signi�cantly more funding for choosing renewable heating technology, all RHI applications made after the 14th December 2016 are eligible for the new tari�.

Plans to introduce these changes in spring have been interrupted by the recent General Election, with the proposal yet to receive Parliamentary approval.

O�ering lower fuel costs and superior energy e�ciency, heat pumps can reduce the impact of fuel poverty and support the UK in reaching renewable energy targets.

In a recent podcast, research and consulting experts Delta-ee said that the updated RHI is set to have the biggest impact in the private homeowner sector.

Enabling homeowners to instantly bene�t from reduced heating costs and Government funding, the updated RHI is set to catalyse the growth of the heat pump sector by attracting new customers to the technology.

However, for installers to truly capture the business potential of the reformed RHI, technical knowledge and awareness of the requirements for RHI applications is needed.

This is of signi�cant importance as Delta-ee previously reported that awareness and education are the key drivers to increase the homeowner uptake of heat pumps. Detailed knowledge of the reformed RHI and its bene�ts alongside expert product insight can therefore lead installers to signi�cant business growth.

submit an RHI application, an air source heat pump that is Microgeneration Certi�cation Scheme (MCS) accredited must be selected and installed by an MCS accredited installer. Furthermore, the RHI application must be made within 12 months of commissioning.

The timing of the application is also vital as the RHI reform makes electric metering for all heat pumps mandatory and puts in place a cap on annual payments for a single property. Limiting RHI payments to 20,000kWh for air source heat pumps, all applications made after the new tari� comes into e�ect will be considered inline with the new eligibility criteria.

To fully demonstrate the bene�ts of the RHI and renewable heating technology,

Timing vital

Consider, for example, a typical 1930s three bedroom, semi-detached property that requires 18,000kW/hrs of heat. The increase in RHI funding equates to an additional £1,970 over the seven-year period, with RHI payments totalling £8,305.

It is important to fully inform customers of the RHI scheme rules. To be able to

installers should lean on the technical expertise, support and tools available from leading manufacturers.

Providing a host of free marketing materials, Daikin UK’s KEY Installer Scheme gives members exclusive access to extended product warranties, technical support, as well as industry and product focused training sessions.

Product focused training courses - such as the Daikin Altherma Monobloc LT heat pump installation course - support installers on their first steps into the industry, presenting the ideal stepping stone to larger units that require F-Gas qualifications.

Incorporating electric heat metering within the units, the MCS accredited

Daikin Altherma heat pump range ensures it is as simple as possible for homeowners to claim RHI funding.

Online tools

Furthermore, for installers new to renewable heating technology, the KEY Installer Scheme offers support and a discount when seeking MCS accreditation. Alternatively, for those without accreditation wanting to offer their customers the benefits of the reformed RHI, Daikin UK can recommend nominated MCS partners to ensure the true potential of the RHI is reached.

KEY membership also gives installers access to digital online tools, accessible

onsite, which can provide instantaneous estimates of RHI funding, property heat loss, as well as technical support.

The RHI reforms are set to catalyse the growth of the sector and strengthen the supply chain. To reap the business opportunities expected from the increase in RHI tariff, installers should look towards leading manufacturers such as Daikin UK. Free -to-use tools, marketing materials and manufacturer support can ensure installers are fully informed of the financial benefits of air source heat pump technology to attract new customers and grow their business.

FLYING THE FLAG FOR

GROUND SOURCE FIRST Matt Smith, Contracts Manager at Flagship Group (left), with Guy Ransom, Commercial Director at Finn Geotherm, in the plant room of the new district heating scheme at Orchard Close, Watton

T

he �rst installation of a communal ground source heat pump for domestic use by housing association Flagship Group is set to cut its customers’ heating bills by hundreds of pounds a year.

The system at Watton, South Norfolk, was installed ultimately to improve the quality and a�ordability of customer heating systems and living conditions in the 30 �ats at Orchard Close.

Previously, the residents at Orchard Close had electric economy 7 storage heaters which were ine�cient and expensive to run.

The new system, which draws energy from the earth, will not only cut people’s energy bills by two thirds, but it also results in zero carbon emissions.

Customers started using the system in April, and although it is communal, each home is individually metered and customers are only charged for the energy they use.

The installation quali�es for the Renewable Heat Incentive (RHI), a government scheme which assists with the project’s capital cost, allowing Flagship to

roll out the much-improved heating system into other homes in the future.

Fantastic solution

Strategic Director for Asset Management at Flagship, Stuart Longbottom, said: “Ground source heat pumps are a low maintenance, sustainable way of heating our homes which are a fantastic solution for our customers.

We are committed to continually improving our renewable energy sources to help tackle fuel poverty and reduce our carbon footprint, and this system does that. Capital investment by Flagship as well as the RHI provides a positive and sustainable return for us and our customers.”

Renewable heating experts Finn Geotherm worked in partnership with Aaron Services to install the system.

Finn Geotherm’s Commercial Director, Guy Ransom, said: “I’m delighted that Flagship have decided to use the technology for their customers. Heat pumps are a well tried and tested technology. Finn Geotherm have been installing systems in the UK, in all kinds of properties, for more than 10

years. The systems themselves are made in Finland where they experience extremely cold weather conditions, so we know how e�cient it can be. Ground source heat pumps are extremely reliable as they should last for more than 30 years. This provides additional reassurance for Flagship and their customers.”

The system is also connected to the Finn Geotherm o�ces, allowing it to be monitored wirelessly.

KEY BENEFITS

₀ Reduced energy bills – immediate and long term ₀ Zero CO2 ₀ Encourages customers to heat their homes, positively impacting on their health – reduction in damp and improved air quality ₀ Low maintenance requirements ₀ Less intrusion for customers as equipment is stored in an external plant room ₀ Lasts three times longer than a conventional boiler

TO O L S TA L K

DIGIMON DELIVERS Dave Kingston, Technical Sales Manager at Javac UK, addresses the requirement for multi-refrigerant temperature scales.

T

he refrigeration manifold is the engineer’s mainstay and most will carry both two and four valve, for various applications.

Analogue gauge manifolds are great but will always be limited by the number of temperature scales on the dial. With the new GWP quotas now in force, 2017-18 will see lower GWP refrigerants and drop-ins coming in with a rush.

The REFCO DIGIMON digital manifold addresses this by o�ering 55 selectable refrigerant scales, covering A2, A2L, A3 and CO2-subcritical, which are identi�ed according to vapour or liquid. This is available at http://www.javac.co.uk/ refcodigimondigital/digimon-test/.

After the required temperature scale is selected, high and low pressure is displayed on screen to class 1 accuracy, in both digital and analogue. Resolution is 0.01bar and the scale will operate between -0.95 to 60bar.

Superheat and sub-cool are taken care of using the K type wire plugin probes or the optional pipe clamp and the display shows a direct calculation, making adjustments to the system much easier.

Although the DIGIMON o�ers a basic

vacuum gauge on screen, the addition of the DIGIMON-VAC plug–in external sensor upgrades it to the same standard as the REFCO REF-VAC digital vacuum gauge. This is a really cost-e�ective way of gaining a high-quality electronic vacuum gauge, within one instrument.

To complete the set and keep everything safe, the uniquely designed carry case securely holds the manifold and all the necessary accessories, including several spare hoses and connectors.

PRIMARY POINTERS

FOR SCHOOL VENTILATION Schools should be an environment where productivity and concentration are paramount. Andy Williams, Technical Consultant at Jaga Heating Products UK, highlights why education design consultants must understand the importance of excellent Indoor Air Quality (IAQ), and identifies the top considerations when selecting a ventilation system for schools.

S

Andy Williams

chools are places where parents send their children each day, with the expectation that they will learn in a safe, productive environment. Education design consultants must make the right decisions when it comes to selecting elements of a school building, including its fabrics, the heating, ventilation, spacing and lighting.

A study by the Education Funding Agency reported that just 5% of the 59,967 school buildings studied were classed as performing as intended and operating efficiently .

If we are to provide an optimum learning environment for future generations, it is crucial that a school’s design is carefully considered. Over 90% of teachers believe that well-built and well-designed schools which consider elements such as lighting, spacing and ventilation will be able to improve educational outcomes and pupil behaviour .

If a school building isn’t effectively ventilated and the Indoor Air Quality (IAQ) is poor, it can trigger respiratory problems, and hamper the concentration and productivity of pupils. With regards

to the UK’s educational outcomes, England currently sits at 27th in the global performance tables for its exam results .

Good quality ventilation in a school could be the key to unlock pupils’ performance potential. Capital investment for schools is an important consideration, particularly as many schools are struggling with a lack of funding. As such, future proofing considerations play a key role. So what qualities should an effective ventilation system possess?

System adaptability is key

Building Bulletin 101 (BB101) “Guidelines on ventilation, thermal comfort and indoor air quality in schools , recommended that when measured at seated head height, during the continuous period between the start and finish of teaching on any day, the average concentration of carbon dioxide should not exceed 1500 parts per million (ppm) (1000ppm for mechanical or hybrid ventilation systems) in a school classroom.

It is crucial that the system chosen can

deliver this. The document also states that, unlike previous versions, schools which are undergoing refurbishment are also advised to adhere to these guidelines.

It is also essential that the system can adapt depending on the number of occupants in each room. It can be a challenge to continuously regulate the air inside a building, which is why a demand controlled ventilation (DCV) strategy is often the most appropriate for a school as it enables the careful monitoring of a space, taking account of the number of people and their activity levels. A DCV strategy enables a system to do exactly what it needs to, when it needs to. A mechanical, DCV solution constantly measures the concentration and rate of change of CO2 in a room via carefully placed sensors,and automatically adjusts the volume of fresh, filtered air that is brought into the room, matching it with the quantity of stale air extracted.

It is also advisable that the school building remains ventilated when pupils are on holiday or outside of teaching hours to minimise overheating for those who use the school for other purposes during this time.

How discreet is the system?

It is important that the chosen ventilation solution blends into the fabrics of the school and doesn’t disrupt the learning

environment. Whilst opening a window is a simple and effective natural ventilation method, it doesn’t allow true control of air quality, and can lead to cold draughts.

Furthermore, if the school is located in a bustling, inner-city location, opening a window could lead to increased noise and air pollution. A demand controlled mechanical ventilation system should be designed and installed to ensure that it can provide enough ventilation to maintain the appropriate air quality, which can then be supplemented by the opening of windows in the right circumstances to bring in additional fresh air on a warm day.

Is it essential that factors like these are properly considered.

Is the solution user-friendly?

Over-engineered schools, with government-specified equipment that very few people know how to operate, is costing schools £150 million per year – a cost which could be minimised if systems and equipment were easier to understand and use. It is recommended that education consultants choose ventilation systems that are simple and intuitive enough so that teachers and other staff can make changes easily. In order for this to work, teachers must be able to understand what the ventilation system does, and how to get it to operate in a different way when necessary. Teachers will instinctively

know that opening a window will allow air to pass through the building, but do they understand the impact that a mechanical DCV system can have?

If educational consultants take these considerations into account when designing a ventilation system, then it is likely that excellent air quality will become commonplace in our schools, and this can help to drive up educational outcomes and enhance the wellbeing of pupils and teachers, as well as giving better control over future running and maintenance costs.

CIAT launches Floway Access compact AHU

CIAT has announced the launch of Floway Access, its new single block compact air handling unit, which extends the range that leads in its category in terms of eco design, energy efficiency and ease of use.

Not only is the Floway range fully compliant with the 2016 Ecodesign Directive passed by the European Commission, it meets the requirements on energy savings and reduced carbon footprint already announced for the Commission’s next regulatory upgrade. In addition, Floway air handling units, as well as the heat recovery units, are certified by Eurovent, a leading industry association active in Europe, the Middle East and Africa.

The highest performance standards are met thanks to its brushless motor and high efficiency plug fan, which allow a wide airflow modulation range, resulting in a motor efficiency up to 90%. In addition, panels are thickly insulated to ensure a quiet operation and range aims to provide a plug and play solution to customers. www.ciat.com

Meet Swegon’s Parasol

A new model in Swegon’s award winning Parasol range has been launched.

Parasol Zenith adds another dimension to the already impressive flexibility of the existing Parasol range, offering greater scope for connection positions, additional unit sizes and a much wider working range and higher capacity. The Parasol has all of the features and energy benefits of a chilled beam as well as the flexibility of a fan coil. Adjustability of both air volume and direction on all four sides gives Parasol the flexibility that has been the only drawback of chilled beams in the past. With no fan, Parasol runs silently and consumes no fan power. www.swegon.co.uk

K65 system provides ultimate high-pressure tube solution

Conex Bänninger, in partnership with Wieland K65 tubes, has developed its K65 fittings for the commercial sector, a solution for high-pressure ACR applications.

Conex Bänninger CO2 solutions can deliver pressure ratings up to 120 bar (1740 psi).

The K65 system also enables businesses to retain their green credentials by utilising the highly pressured CO2 R744 refrigerant. Suited to a range of highly pressured refrigeration and air conditioning applications such as installations in office blocks, high rise apartments, schools and supermarkets, the K65 system simplifies specification as there is no tube gauge variation in both Wieland’s alloys and Conex Bänninger’s complementary fittings range.

Both the tube and fitting components of the K65 system are UL 207 certified. The K65 range’s excellent processing properties, similar to those of copper, mean fittings can be easily brazed to the tubing without special equipment. www.conexbanninger.com

Daikin’s self-cleaning solution for internal duct �lters Daikin UK has launched new product to keep internal duct filters clean on its VRV and Split units.

The Auto-Cleaning Duct accessory also claims lower maintenance and running costs, a longer lifespan for systems and 20% energy saving.

Designed for hotels, offices and residential applications, the accessory will prevent dust formation within indoor ducted units by keeping the filter consistently clean thanks to an automated filter cleaning system. Collecting debris in a dust box that can be simply emptied using a standard vacuum cleaner, the Auto-Cleaning Duct accessory promises easy maintenance access and minimal disruption on site.

Daikin UK’s Martin Passingham said: “This is a cost-effective and energy efficient answer to ensure the units do not become clogged with dust and consequently reduce the system’s efficiency and lifespan. The kit also offers easy installation, while reducing maintenance needs and filter system cleaning time on site.’’ www.daikin.co.uk

ADVANCED SUPPORTING

NEXT GENERATION

Advanced Engineering is supporting the next generation of engineers by donating 25 new refrigeration recovery units worth £33,000 to the College of North West London.

Students training at the college for careers as air conditioning and refrigeration engineer had been learning their trade on ageing equipment, which was costing the college around £3,000 a year in service and maintenance costs. Advanced has also included a three-year package of support to ensure that, should the need arise, the units will be repaired at no cost to the college.

Luke Levens, Sales Manager at Advanced Engineering, said: “Our partners at the college have been doing fantastic Precision Refrigeration work withBritish these manufacturer young people, so we’re doing our bit as is helping triathlete with her and aims they usher through the nextFrancesca wave of airHall conditioning to win a gold medal at the 2024 Olympics, the refrigeration experts.” company announced this week.
