The new circulator has been designed specifically forapplications like heating systems, cooling systems, domestic hot watersystems, solar systems and geothermal systems.

The smaller 100 Watt models for light commercial applications havethe unique Anti-Block Technology already existing in the ecocirc series.This technology reduces pump downtime and maintenance costs as itcompletely separates the main flow of the pumped liquid from thepermanent magnetic parts, meaning the pump is never susceptible toblockages from magnetite or sludge. The larger models for commercialapplications utilise a canned motor design with filters.

The range is made up of DN 25 to DN 100 models in single head, twin heads and bronze pump housing configurations.

The Lowara ecocirc XL and XLplus come with a variety of controloptions as standard, including proportional pressure, constant pressure or constant curve.

In addition, the “automatic night setback” mode ensures that thecirculator reduces its performance level to a minimum when not needed,thus enabling a further reduction in energy consumption and costly utility bills. All settings can be controlled by an easy-to-use display withintuitive interface design.

Terry Murray of Xylem Water Solutions Ireland commented: “Following the success of the ecocirc, we wanted to develop a circulatorfor commercial applications which could meet heating and coolingrequirements across a broad range of applications but still maintain the value and energy efficiency that we have come to expect with theecocirc series.

“Our ecocirc XL circulator offers clear energy efficient features and isvery easy to install, set and use. With this state-of-the art high efficiencydevice, we have reduced the complexity for the user to a new minimum.”

The circulator also features a very easy-to-use digital interface to keep the user informed of key pump performance information such asoperating or fault mode, flow control and set point. Further in-depthinformation such as historical pump data, the live situation as well asmany additional settings can also be easily accessed either through alaptop via a RS485 port, or through an optional wifi module and standard wifi-enabled device, such as laptop, tablet, or smartphone.

If using a smart phone, a specific app is not required as all data and settings can be accessed through the standard browser installed on the wifi-enabled device.

For use in installations with building management services, the ecocirc XLplus embeds either Modbus RTU or BACnet communicationcapabilities.

My interest in lighting wasinadvertently sparked as anundergraduate. A student ofengineering and already fascinatedwith research, I was curious as to the effect on the electrical grid ofreplacing traditional incandescentlamps with, at the time, the mostenergy efficient alternative –compact fluorescent lamps. Ipondered displacement power

factors, distortion power factors andharmonics, and what would happen if we were to all instantly switch (as thegovernment was encouraging). Inhindsight, I was suffering a severe boutof tunnel vision, but this was very muchcured by some inspiring doctors at DIT. So I veered, began reading about allaspects of lighting and soon fell in love.

Skip to the present. I am neck deep ina lighting-related PhD at DIT, working asa lighting designer with Arup and evenmore absorbed in lighting than I couldever have imagined possible. A seismicshift from where a younger selfpredicted he would currently be.

LondonJune 2nd 2014. It happened, albeitbelatedly. I shuffled nervously throughthe revolving doors, past the art gallery,then upstairs. Here I was introduced topeople whose names I knew, alreadyadmired and in some cases borderlineidolised. The Promised Land: my journeylengthy, but my stay temporary. I applied for a position in London aboutfour years ago but never got called tointerview. Now that I’ve snuck in, it’s only for a year. I’m working with, andlearning from, the wealth of knowledgethat exists in the Arup lighting team here in London.

So anyway, London,c’mere to me, what’s the craic?My perspective and outlook might bepartially skewed, or even tinted, giventhat a return home is guaranteed forme. Either way, the following are somethoughts, reflections, impressions andfeelings of my time to date in the UK’simitation of the real Big Smoke.

Thuas SealThe specific upsides of my time inLondon have been many, but theprojects, the people and some oldclose friends have made life here morethan enjoyable.

The projects … well they just don’tcompare. Each site, building or spacewe design seems to be a landmark.

Stadiums, museums, bridges andairports are doing rounds at themoment. Renowned architects almost the norm: Richard Rogers,Renzo Piano, David Chipperfield, Zaha Hadid – just some of the namesto be overhead from my desk. Theyare, geographically and metaphorically,worlds apart from what I’maccustomed to.

The London Eye, agiant observationwheel located in theJubilee Gardens onthe South Bank.

The Tower Bridge has become an iconicsymbol of London.

The world over, the

Irish are generalised

as friendly, amicable,

fun-loving people.

The rationale

behind this only

became apparent to

me when I moved

somewhere like

London: impersonal.

‘


The people … well they have what Iwant. I am here, for the most part, torefine my RADIANCE skills. For thosethat don’t know (those with sense!)RADIANCE, in its purest form, is acommand-line based program used forcomplex simulations that enablesincredible flexibility through scriptingfrom first principles. The downside …it’s not so user-friendly. The team herehave been amazing at sharing theirknowledge with me and in the first fivemonths I’ve progressed more thanduring three years of teaching myself.

The social life … well it’s whateveryou want it to be. London hassomething for everyone and while myPhD keeps me busy weeknights andmost weekends, when I take a breakmy life is mine. I do as I please andwhat I please is right at my doorstep.From the British Museum to TateModern, the Adelphi to the Apollo,Highbury to Twickenham, Brick Lane toJamie’s Italian, Shoreditch to Dalstonand Saturday nights to Sundaymornings. Like most Irish people here Ihave the opportunity to surroundmyself with a number of childhoodfriends and, if I’m out with them,excluding the sketchy Guinness, itoccasionally feels like home.

Thíos SealWhile my life here has numerousupsides, there are still countless things

about home I crave – my girlfriend, myfamily, my friends, general familiarity,Dublin humour, a decent pint of stout… the list is eternal. For weeks I tried toput my finger on what exactly, beyondthe obvious, I missed so much. One dayit hit me – Irishness – if such a termexists. The world over, we aregeneralised as friendly, amicable, fun-loving people. The rationale behindthis only became apparent to me whenI moved somewhere like London:impersonal. Personally anyway, there

truly is something different aboutworking in Dublin.

Here, my lunch is brief, it’s eatenalone and at my desk, chats whilemaking tea are rare and when they do break out, they centre on work-related small talk. Social interaction is organised weeks in advance and aFriday pint is rare and singular when it happens. To bond with colleagues I must dismantle the professional force-field they so fearfully exhibit. It’s a bigask when you haven’t got the tools.

Bíonn adharca fada aran bhó i bhfad ó láthairIn short, I guess that’s what I’veexperienced to date – six of one and a half dozen of the other. There aremany things I will learn in London and even more things I will appreciatewhen I return home. It’s a strangefeeling for me – I’m excited to leave,but I will miss London the moment my plane touches down in Dublin. ■

... experts in Field Controls

Sontay is celebrating an importantmilestone this year with 2014representing the 40th anniversary of the company, now firmlyestablished as the market-leadingmanufacturer and distributor of field control devices for the HVACand climate control sector.

Its popular wireless sensortechnology, SonNet, is having afundamental impact on how we thinkabout the cost of installation. Byeliminating the need for structuralcabling during sensor installation,wireless devices can greatly reduceengineering time and installed projectcost. This enables faster and easier

installation on new buildings, andalso opens up the opportunity forcontrol specialists to retrofit energy-efficient HVAC controls into existingcommercial and public buildings.

In projects featuring the SonNetfamily of wireless sensors such as the Guildhall Art Gallery or theCommonwealth Games TollcrossInternational Swimming Centre, weare typically finding total installedcost savings of 30% and more overcomparable wired sensorinstallations. At a time when reducingcosts is a priority on many projects,proven wireless technology can bringsignificant benefit.

CELEBRATING 40 YEARS OF SONTAY

At a time when

reducing costs is

a priority on

many projects,

proven wireless

technology can

bring significant

benefit.

‘

Evolution of SonNetIn 2010, Sontay introduced the ground-breaking and award winningSonNet wireless sensor system, an innovative solution thateliminated the need to install structural cabling and greatly reducesengineering time and installed project cost. By using the site surveykit, SonNet can also prove signal strength and map a network beforeinstallation, thus removing any hesitation when choosing a wirelesssystem over a traditional wired one.

This year Sontay introduced a RF-IOM-4A-4U input module whichworks in conjunction with SonNet sensors and routers. This cleverdevice acts as a local I/O with connectivity to typical HVACequipment, such as fan coil units or variable air volume boxes. Themodule can take any 0-10Vdc, 4-20mA, resistive or VFC signal fromwired devices in the field and transmit them to a SonNet RF-RXSreceiver. This in turn can be read by a JACE controller through aNiagara framework. The strategy within the controller uses thisinformation to calculate control values, which are then passed backthrough the I/O module to alter damper positions and other outputconnections in the field.

The Guildhall Art Gallery in London is one of many buildings to benefitfrom SonNet.

Today, not yet three years down theroad, OML Ventilation is a thriving businessemploying 17 people and still growing. Trevorstarted with a small crew, specialising in theprovision of ventilation and related servicesacross a wide spectrum of industries.However, the pace of growth took him bysurprise with the business expandingorganically, virtually all new work coming by way of word-of-mouth recommendation.

This was hardly surprising given Trevor’sstanding and reputation in the ventilationsector in Cork and throughout Munster. Fromwhen he first started as an apprentice sheetmetal worker with GB Services in 1995 towhen he finished up with the company asContracts Manager 17 year later, he gainedinvaluable experience.

“It is only in hindsight” he says, “that Irealise just how important that whole 17-yearperiod was in preparing me to run my ownbusiness. To a great extent you are too busyto notice these things but, when faced withthe challenge of establishing and managingmy own concern, I found I had a great deal ofknowledge and experience to draw on.

“In addition, I had great industry contactscovering both potential clients and a networkof qualified and experienced tradesmenwhom I could employ. Consequently, as thebusiness grew, I was able to build the teamrapidly to deliver top-class ventilationsolutions across all industry segments, from pharmaceutical through to industrial,commercial and retail applications.

“We do everything from ventilation andextraction systems through to air handlingunits, dust extraction, insulation, cladding etc.Clients include Baxter Healthcare, CorkInstitute of Technology, Merck Millipore,Johnson Controls, MSD Brinny, John Sisk &Son, Pfizers, Irish Blood Bank and many more”.

That is not to suggest that it was all plainsailing, the biggest challenge being to get thework/lifestyle balance right. Trevor is notafraid of hard work, or of putting the hours in.However, that makes for a 24-hour role, sevendays a week. It is something he is consciousof, and something he is starting to address, by building a strong back-room team toprovide administration, costing, design and project-analysis support.

Site-assessment is a critical part of theprocess with every individual situationthoroughly assessed and analysed before anysolution is proposed. This applies whether it is a new-build, refurbishment or retrofitscenario. Lifecycle costs, energy efficienciesand regulatory compliance are also primeconsiderations.

Trevor is disciplined, attention to detail onprojects and the manner in which they aredelivered being as important as the solutionitself. This also applies to the paperwork andmanuals associated with each project.

In essence, OML Ventilation delivers clientsolutions in a very professionalism mannerthat, at the same time, allows for flexibilityand common sense intervention whereappropriate. ■

OLDEN BUCKS THE TREND

When facedwith thechallenge ofestablishing andmanaging myown concern, I found I had agreat deal ofknowledge andexperience todraw on.

‘

When Trevor Olden set up OML Ventilation Ltd inMarch 2012, the building services sector was perhapsat its lowest ebb. Some would argue – and indeedmany did – that it was not the best time to go it alonebut, undeterred, Trevor took the plunge. It was thebest career/business decision he has ever made.

Whether in an office complex, hotel or residential building, in order to reduce the energy consumption of a building it isnecessary for the various functions such asheating, cooling, ventilation, lighting andshading to be adapted to one another andoptimised. At the same time, automation can significantly increase the well-being ofbuilding users, while also making energy usemuch more efficient – intelligent networkingof building services provides an energy-saving potential of up to 30% in officebuildings, for example.

However, it is not just energy costs thatcan be reduced, but also expenditure onmaintenance and personnel. This meansconsultants are faced with significantexpectations to develop integrated conceptsfor buildings in order to optimise operationwith regard to energy consumption, comfortand operating costs.

Intelligent pumps provide synergyClever pump technology makes a significantcontribution to energy efficiency, because alot of pumps are used for heating, cooling,air-conditioning, water supply and sewagedisposal. Old, uncontrolled pumps consumea lot of electricity, whereas the electronically-controlled pumps from Wilo offer the besttechnological conditions for effectivebuilding automation. These pumps have amodular bus connection concept throughout,thereby allowing them to be integrated intoany automation and control technologysystem without difficulties.

Wilo offers plug-in interface modules forthe various commonly-used bus systemssuch as BACnet, Modbus or CAN bus thatare used in building automation. As a result,Wilo pumps with IF-Module can be quicklyand easily integrated into buildingautomation systems, even retrospectively.

The appropriate module – analogue ordigital – allows electronic pumps from Wiloto be integrated as intelligent actuators andsensors in building automation. They act as a link between the hydraulic circuits and thecontrol devices of the field and automationlevels and offer significant synergy effectswith regard to the use of energy, comfortand operating costs.

The great flexibility of IF-Modules is also oriented towards the future. If theautomation system is upgraded or changedat some point going forward, it is only

necessary to exchange the IF-Module on the device, and not the complete pump.Exchanging takes a matter of moments, andsaves at lot of time and expense. This is animportant aspect for consultants who gain a great deal of freedom with this adaptable,modular solution.

With plenty of forethought, Wilo hasaccounted for the rather short life cycles ofinformation technology in its calculations.Furthermore, consultants can be sure thatthe system they have planned will remainusable for a long time.

By combining reliable high-efficiencypumps with flexible interface modules, Wilomakes consultants' everyday work easier and gives them, and their customers, thenecessary security for the future.

Advantages of IF-Modules – Unique, consistently-integrated modular

bus connection system;– Available for all conventional bus systems:

e.g. Modbus, BACnet, CAN, LON and PLR;– Retrofittable IF-Modules enable direct

data communication with controllers,actuators and sensors from othermanufacturers;

– Installation and removal using plugconnection;

– In system upgrades or replacements, it isonly necessary to exchange the IF-Module,and not the pump itself.Contact: Wilo Ireland, Technical Sales

Intelligent pumpsolutions for buildingautomation


Building automation is the key to the most efficient possible use of energyand a high level of comfort for building users. By far the greatest factor inthis is the pump technology, which is why Wilo provides a straightforwardconnection to the automation system with the flexible interface module(IF-Module), writes Derek Elton, Sales Director, Wilo Ireland.

Wilo-CAN: the high-speed interface – lesswiring required; high transfer speed andfunctionality; open standard protocolCANopen; multimaster capability.

Each pump is a complex system– a look under theshell of the Wilo-Stratos GIGA.

PRODUCT REVIEW: RADIATORS

Budget permitting, somedomestic and commercialapplications are no longer lockedinto the more traditional solutionssuch as compact or round-topradiators. These have their place andcontinue to provide a very effective,efficient and cost-effective solutionfor all types of applications.

However, where funds areavailable the use of newer, morequirky radiator styles has beenfacilitated with the increased levelsof insulation now being utilised in both refurb and new-buildprojects. The reduced heat outputrequirements means designers can be a bit more creative in theirradiator selection.

The ideal solution is a balance of the aesthetic impact coupled to space availability and theperformance requirement. Typically,most of these newer styles have alower output than traditionalsolutions so care must be taken to ensure that the heat/comfortrequirement is not sacrificed foraesthetics. In some cases theseradiators can be used as asupplemental heat source to other forms of heating.

Radiators can now be interpretedas art but it is important to realisethat art is a personal taste issue and the selection must also be fit-for-purpose, depending on theapplication. They also require moreinvolvement with the client in termsof selection and placement withinthe room so it is extremelyimportant for the designer andinstaller to liaise closely with theclient when advising on availablechoices.

Opportunity forincreased margin indesign-led, avantgarde radiator styles Previous articles focussed on the more technicalaspects of radiator selection based on the need fora detailed heatloss calculation and accurateselection of radiator output, to provide sufficientheat/comfort for the application.

In this article Frank Donohoe of Donohoe HeatingServices takes a different path and explores themore avant garde radiator alternatives now beingmade available.

Can you spot the radiator in this modern roomsetting? Clue: the artistic “wall hanging”featuring the zebra head is not all it seems!

Rads intro:Layout 1 21/11/2014 08:27 Page 1

Some radiator manufacturers arenow retaining designers to come upwith totally different solutions tospace heating. These new-styleradiators are generally marketed forliving areas, bathrooms and in somecases office space.

In living areas it is not uncommonnow to see floor to ceiling column,multi-column or vertical panelradiators. These have set the trendfor designers to think outside thenormal envelope and offer theopportunity of more style-drivensolutions. Some of these are deemed“brave” and require a client to beprepared to explore more creative

options and focus on the visualimpact.

Bathrooms have seen the use ofladder-style towel radiators becomealmost standard with chrome unitsbecoming more commonplace thanwhite. Key advantage is that thesenew design make for a “feature”radiator that provides both form and function.

From a manufacturer and installerpoint of view these more avantgarde solutions also offer anopportunity for increasedmargin/added value on a project.Given the competitive environmentpertaining we should not lose sight of these opportunities.

Now to conclude with a final note of caution. Many a selection ofdesigner-style radiators is let downby the placement of pipework, orthe valve selection. When going thisroute remember to take a holisticview of the entire installation andensure that all ancillary items are inkeeping with the “wow” factor ofthe radiator choice. ■


Is it a vertical light unit or uniquely-styled wallcabinet? No, it is the room’s radiator.

This radiator could pass for a classy, architecturally-designed, drop-down ladder providing atticaccess over the bathroom

These moreavant gardesolutions alsooffer anopportunity forincreasedmargin/addedvalue on aproject. Giventhe competitiveenvironmentpertaining weshould not losesight of theseopportunities.

For rooms such as the kitchens, space is often an issue. Consequently, vertical radiator models and towelwarmers can prove highly-effective. A vertical radiator can take advantage of the smallest wall space while thecompact design of a towel warmer means it can often bepositioned at the end of a storage unit. From traditional to ultra-modern interiors, the vast array of towel warmerdesigns on the market also allow for a dash of style to be added.

Even more discreet is the Kickspace fan convector, whichis installed in the plinth of a normal base unit, so taking up no wall space.

As for bathrooms, these can be a particularly humidenvironment and a chrome finish on a bathroom towelwarmer or radiator will cope with normal levels ofhumidity. However, for bathrooms with no outside wall and no natural ventilation, a powder-coated finish mayoffer increased longevity.

For areas such as living rooms and bedrooms, or evenstylish office spaces, the client may wish to have a designerproduct, like those in the Myson Design Collection. As wellas providing ample warmth, they are also stylish features in their own right.

Manufactures now offer radiators in styles ranging fromthose that look like the retro cast iron models from the past

to abstract vertical designs, with the added benefit of outstanding

modern performance.

The days of sacrificing appearance for functionality andefficiency are long gone, as is the “one size fits all”approach. When selecting the boiler/radiator combination,specifiers and installers should also carefully consider theheat source options, and the means by which the heatoutput is controlled.

The drive for efficiency has seen manufacturers developnew-generation heat emitters that combine the staticoperation of a radiator with the dynamic functionality of a fan convector in the one product. The Myson ULOW-E2 is an excellent example of this. The E2 technology detectswhen the air temperature drops and activates the fans toquickly boost the temperature back to a level that iscomfortable, before returning to static functionality.

Panel radiators have also been developed in recent years to ensure optimum performance in terms of energyefficiency. With lower water content and higher surfacearea provided by additional fins, panel radiators can emithighly-satisfactory levels of comfort heating from smallersizes and lower system temperatures, making themproducts of the future to be teamed with renewable, aswell as traditional heat sources.

The lower system temperature is a huge bonus to energyefficiency, especially when coupled with a condensingboiler, as the lower temperature enables the boiler to work in condensing mode for longer periods, reaping thebenefits of its energy saving credentials.

When considering heat emitters, installers and specifiersshould also consider underfloor heating. Manufacturershave made underfloor heating increasingly versatile withnew products like the low-profile Microboard beingsuitable for installation over existing floors in retrofitsituations, or as part of a new-build. It is ideal for roomswhere wall space is at a premium.

It is only by considering individual heat emitters, systemcontrols and end-user needs together that the overallheating system will deliver the most comfortableenvironment, with efficient performance, for the most cost-effective running costs.

The change is not just a cosmeticupdate. Behind it lies a reflection of thestronger alignment of the company on aglobal scale with IMI plc (to which the group belongs) and the two other divisionsIMI plc owns – IMI Critical Engineering andIMI Precision Engineering.

Since the arrival of Mark Selway, the new CEO in January 2014, a new era in thedevelopment of IMI plc and its divisions wasstarted. The group has strengthened its focuson providing customers and partners with even better products, quality and service, and the new visual identity is an expression of these changes.

With experience in over 100,000 projectsworldwide, the IMI Hydronic Engineeringdivision combines unrivalled system knowledgewith the most innovative hydronic technologyto engineer bespoke, energy-efficient solutionsfor HVAC installers, designers, consultants,contractors, commissioning agents andmaintenance companies.

With over 20% of the world’s energy used inHVAC systems in buildings, solutions that offer

savings and efficiencies while maintainingindoor comfort are increasingly in demand.That’s a tough challenge which IMI HydronicEngineering has readily taken on. In the last 12 months it introduced no less than 15 newproducts, all developed to generate efficienciesin HVAC systems without compromising on theindoor comfort of end users.

Take the Zeparo Cyclone for example. This is a new dirt separator with cyclonictechnology that removes dirt from systems up to nine times more effectively than other solutions currently available on themarket. That means less problems caused by corrosion or the breakdown of vitalelements such as pumps, boilers or even chillers.

Then there is recently-launched A-exact with AFC (automatic flow control) technology. This innovative control cartridge can be used in radiator valves orunderfloor heating manifolds and guarantees a constant flow rate once it has been set. Iteliminates excess heating power when neighbouring valves are closed, and the

HVAC system can ensure an optimumtemperature distribution in a more efficientmanner. For installers the benefits are clear too – it is fast and easy to mount, hydronicbalancing occurs automatically, and there is no need for complex hydronic calculations.

Peter Spencer, Managing Director, IMIHydronic Engineering, is very excited about the future and the recent companychanges. “Providing a comfortable indoorclimate which is also energy efficient is at theheart of what we stand for”, Peter toldBuilding Services News. “Our commitment tosaving energy in HVAC systems goes beyondjust providing our customers with innovativeproducts; it’s the understanding of the system as a whole. With 20% of the world’senergy used in HVAC systems there is massivepotential for energy efficient solutions that can reduce energy bills.

“As part of a global group with an ambitious future, I am proud to be part of the transformation we are undergoing as abusiness, and excited about the launch of the new visual identity of IMI HydronicEngineering”.

PRODUCT REVIEW: REFRIGERATION

The effects of these changes will be

dramatic and, over the course of a decade

or so, the phasing in of different parts of the

F-Gas Regulation will change the way we

design and use RACHP equipment that

utilises HFC-based refrigerants. The F-Gas

Regulation is a wide-ranging piece of

legislation and covers many areas of industry

that use F-Gases, not just the RACHP sector.

The following details the most important

points that need to be followed to ensure

compliance with both the ODS and revised

F-Gas Regulation for those working in any

area of the RACHP industry.

The Regulation (EC) 1005/2009

on Ozone Depleting Substances

• Reclaimed R22, or any HCFC sale

and usage, will be banned after

31 December 2014;

Existing equipment will not have to

be decanted of its refrigerant but it can

not be charged with reclaimed/recovered

HCFCs as from the 1 January 2015

under any circumstances;

• Any HCFCs recovered after 31December

2014 MUST be sent for destruction;

• HCFCs recovered during servicing or

maintenance after 31 December 2014

cannot be returned into the system and

MUST be sent for destruction;

Caution

If retrofitting existing HCFC plant to a

HFC-based alternative refrigerant, be very

careful what retrofit alternative refrigerants

you offer end users/customers. Do not

recommend high GWP retrofit replacement

refrigerants. Many of these products will be

hit hard by the recently-amended F-Gas

Regulation and future availability is likely

to be a serious issue.

F-Gas Regulation (EU) No 517/2014 –

the phase-down mechanism

The main plank to reduce the amounts of

F-Gases (HFCs) both placed on the market

and used in the EU will be governed by the

Revised F-GasRegulation tohave majorimpact on RACHP industryOn 1 January 2015 the RACHP industry is due a shake-up of a

magnitude not experienced in most people’s living memory. The

revised Regulation (EC) 1005/2009 on Ozone Depleting

Substances (ODS), which came into effect

on 1 January 2010, reaches its climax

and requires that all EU member states

stop supplying and using reclaimed or

recycled HCFCs (primarily R22 and other

HCFC-based retrofit refrigerants) after

31 December 2014.

The effect of this Regulation is

compounded by the recently revised

F-Gas Regulation, (EU) No 517/2014,

which will come into effect the day

after, on 1 January 2015. The revised

F-Gas Regulation will have an impact on what alternatives can

be used to retrofit existing R22/HCFC-based systems and also

on the general use of HFCs in the RACHP sector.

Dewi Garcia, MSc, MInstR, Technical Manager, Harp

International Ltd, reviews the implications of these changes and

offers suggestions as to how best deal with them.

phase-down mechanism. The Regulationintroduces a phase-down in placement onthe market involving a gradually-decliningcap on the total amount of bulk HFCs (intonnes of CO2 equivalent) placed on themarket in the EU.

The 2015 baseline amount is determinedby collecting manufacturing and sales datafrom manufacturers, importers and suppliersof bulk F-Gases between 2009 and 2012. Theaverage of this period will be the maximumamount placed on the market on 1 January2015. Over subsequent years between 2015and 2030, the amount placed on the marketwill then be reduced as detailed in Table A.

The Regulation bans few, if any, F-Gasesbut the implication of the above phase-down is obvious in that if we carry on usingHFC-based refrigerants at the current rate,then with only 21% of the amount availablein 2030 than there was in 2015, there won’tbe enough for people to use!

Another subtle effect of the legislation isthat manufacturers and suppliers will begiven an allocation quota based on CO2tonnes equivalent. So, if for instance amanufacturer or supplier is given a onemillion tonnes CO2 equivalent quota, theycan choose what refrigerants they want tomanufacture/supply. If they choose to supply

R404A, which has a high GWP (3920), then

the million tonne quota would allow them to

sell 255 tonnes of R404A. If they chose to

supply R407A (GWP = 2107), then they

could place 474 tonnes on the market. If

they choose R134a (GWP = 1430) they could

place 699 tonnes into the market. Manufacturers and suppliers make money

selling physical kgs of refrigerant, not CO2kg equivalents, and obviously will choose to

manufacture and supply refrigerants theycan sell more of, i.e. lower GWP HFCs. Sohigh GWP refrigerants, without being bannedoutright, will just wither on the vine,especially as time moves forward to 2030with ever-decreasing amounts being allowedon the market, and the use of high GWPrefrigerants in equipment being banned. See Table B.

There are very few HFCs with GWP valuesbelow 150. This leaves hydrocarbons (GWP = 3), ammonia (GWP = 0) and carbondioxide (GWP = 1) as the only viable options,along with the new fourth generation HFOrefrigerants such as R1234yf (GWP = 4) and R1234ze (GWP = 6). However, many ofthese may not be suitable for many of theapplications listed in Table B.

Servicing/maintenance restrictionsThe use of fluorinated greenhouse gaseswith a GWP> 2500 to service or maintain

refrigeration equipment with a charge size of40 tonnes of CO2 equivalent or more will be prohibited from 1 January 2020. This does not apply to military equipment orequipment intended for applications designedto cool products to temperatures below -50°C.

So what does all this talk of 40 tonnes of CO2 equivalent or more really mean forsome of the commonly-used refrigerants?

The maximum allowable charge weightsfor some of the popular high GWPrefrigerants are illustrated in Table C.

Reclaimed and recycled refrigerants with a GWP value greater than 2500 will beallowed to service equipment with chargesize of 40 tonnes of CO2 equivalent or more,but it is possible that there will not be vastamounts of them available. Contractors whoare retrofitting R22 systems over to the“easy, no oil-change retrofits” such asR422A (Isceon 79), R422D (Isceon 29),R434A (RS-45) etc should think carefully as,

after 2020, these will almost certainly not bewidely available. They could end up havingto retrofit the initial retrofit to another lowerGWP refrigerant!

Leak checksFrom 1 January 2015 operators of equipment that contains fluorinatedgreenhouse gases in quantities of fivetonnes of CO2 equivalent or more, and notcontained in foams, must ensure that theequipment is checked for leaks. This appliesto operators of stationary refrigerationequipment, stationary air conditioning

equipment, stationary heat pumps,stationary fire protection equipment, andrefrigeration units in refrigerated trucks andtrailers. Table D shows the banding and thereduction in inspection intervals if fixed-leakdetection systems are installed on the plant.

So, what does this mean in simple termsfor some commonly-used refrigerants? The answer is depicted in Table E.

There is an exemption until 31 December2016 for equipment that contains less than3kg of fluorinated greenhouse gases orhermetically-sealed equipment, which islabelled accordingly, and contains less

than 6kg of fluorinated greenhouse gases.While not subject to the detailed leak checksas outlined in Table E, this only gives ayear’s grace. The onus of ensuring the leakchecks are carried out is on the equipmentowner. I am not convinced that manyequipment owners will be aware of thisrequirement so it is important thatcontractors advise their customers of this as soon as possible.

Labelling requirementsFrom the 1 January 2017 refrigeration andair conditioning equipment placed on themarket containing F-Gases must be labelledwith a reference that the equipment contains fluorinated greenhouse gases, the name of the refrigerant, the quantity ofgas expressed in kg and CO2 equivalent,along with the GWP value of the refrigerant.See Figure A.

Obviously, newly-manufacturedequipment will have the labelling done inaccordance with the Regulation. However, if a contractor does a site install in say abutcher’s cold room and does not know thecharge beforehand, he will be required tocalculate the tonnes CO2 equivalent chargeweight once the system is charged andcommissioned, and then label the system accordingly.

These are some of the more importantaspects of the revised F-Gas Regulation that affect the RACHP industry. As I said at the start, the Regulation is very detailedand does cover many other things. Hopefully, the foregoing makes clear theduties placed upon equipment owners andthose involved in installing, servicing andmaintaining equipment containing HFCs. ■

Organisations are increasinglyseeking total project solutions for climatecontrol, from design through servicing,and demand high levels of comfortcombined with lower energy costs andCO2 emissions. To achieve these aims, a major step change was required andDaikin has delivered with the VRV IV heatrecovery system.

With its state-of-the-art equipment andsmart controls, VRV IV heat recovery

integrates heating, cooling, ventilation,air curtains and hot water, recovering“free” heat from areas requiring coolingand using it to heat other areas andprovide hot water.

For offices, hotels, restaurants, leisurecentres, healthcare environments, shops and public buildings, this means optimal comfort at very high efficiencies (COPs up to 10).

Most efficient now betterDaikin’s three-pipe heat recovery systemswere already considered among the mostefficient on the market but threerevolutionary innovations – variablerefrigerant temperature technology,continuous heating during defrost and the VRV configurator – have raised the bar even higher.

Variable refrigerant temperaturetechnology is at the heart of the dramaticincreases in efficiency. By continuallyadjusting refrigerant temperature tomatch heating or cooling demand and theoutside temperature, less power is needed,efficiency is 28% higher and comfort is improved. An added benefit is thathigher refrigerant temperatures prevent cold draughts.

Continuous heating during defrost alsoimproves comfort, avoiding a drop in

indoor temperatures during the defrostcycle as can happen with some othersystems. This makes the VRV IV systemideal when specifying monovalent heatingapplications.

Finally, the VRV configurator softwarespeeds up installation and commissioningand allows multiple systems at differentsites to be managed easily.

Flexible and efficient designWhen it comes to design, VRV IV heatrecovery systems are also very flexible.Their modularity allows them to be scaledto fit any size of building and to bereconfigured easily if occupant needs orinternal layouts change. Flexibility isenhanced by new and unique single andmulti-port BS boxes, which also makesystems faster to install and are quieterthan ever before. For a complete buildingsolution Daikin’s Intelligent TouchManager can link climate control withother third-party systems.

Fast and efficient installationInstallation and maintenance are fasterthan ever, thanks to the VRV configurator.Daikin’s single-port BS box was developedspecifically for difficult-to-reach areas such as small ceiling voids. The new multi-port BS boxes have up to 16 ports anddramatically reduce installation time whencompared with installing single BS boxesalone. With both the single and multi-port BS boxes available, Daikin offers the ultimate flexibility for installation, all while offering the advantages of a 3-pipe system.

Daikin uses a three-pipe system becauseit is a far more efficient way to recoverheat. In a two-pipe system gas and liquid refrigerant flow as a mixture, so the condensing temperature has to behigh to separate them and recover heat. A three-pipe system’s dedicated gas andliquid discharge pipes means heat can be recovered at a lower condensingtemperature, which means less energy isused and the system is far more efficient.

Among the benefits the new sensor offers are:

• Detects human activity andadjusts temperature by twodegrees (up or down) to optimise comfort and efficiency;

• If there is no activity detected for a set time, the Econavi willstop the unit or move to a newtemperature previously set;

• Modifies temperature output inreal time depending on needs of room;

• Compatible with cassette, wallmounted, hide away and ceiling systems.The Econavi detector was

designed to maximise comfortlevels, be it a hotel room, shop or meeting room. The sensoreliminates the need for physicaladjustment in order to control the temperature of a room, instead automatically adjusting thetemperature depending on a seriesof factors. These include humanactivity (presence or absence), highor low-level of movement, and theoutdoor temperature.

The sensor works in real time to detect human activity within a room. With ultimate precision, the detector will work with the air conditioning system to adjusttemperatures and energy output

accordingly, saving energy costs andefficiency. The automatic detection ofan empty room will shut down theentire air conditioning system, reducingwasted heat and energy levels.

If human activity levels are high, theEconavi sensor will consider humanheat, adjusting the air conditioningsystem to reduce the heat output andinstead set a cooler temperature. Thisalso works in reverse, detecting low-level activity and increasing thetemperature by one degree every two minutes.

If the area is empty after 20 minutes*

in the heating mode the room set pointis reduced by 2ºC and increased by 2ºCin cooling mode. After three hours* thesystem will automatically turn itself off.This real time function means thedetector is constantly adjusting forideal temperature and energy output.

The Econavi sensor is ideal for airconditioning systems located in avariety of applications. For hotels, if the guest forgets to turn the airconditioning system off when theyleave the room, the Econavi will detectand take action. For a busy shop, theEconavi will increase the air flow,improving comfort. When the shopfloor is quiet, the Econavi will reducethe air conditioning, leading toincreased savings for the store owner.

For office applications, in anunoccupied meeting room, Econavi willturn off the air conditioning. Once theroom becomes occupied, the sensorwill increase the air flow to create amore comfortable environment.

The Panasonic Econavi sensor iscompatible with cassette, wall mounted,hide-away and ceiling air conditioningsystems. The discreet box can beinstalled anywhere within a room, and arrives ready to use for easyinstallation.

The Liebert AFC combines theexceptional levels of energy efficiencyallowed by adiabatic free-cooling,together with the endless availabilityguaranteed by the multi-scrollcompressor back-up. This pioneeringadiabatic system enables waterevaporation which lowers the airtemperature entering the free-coolingand condensing coils, consequentlyincreasing free-cooling operation and mechanical efficiency.

Moreover, it maximises free-coolingall year round while maintaining100% cooling availability, even underthe most critical conditions. Theseinclude fluctuating power supplies,water shortages and extreme external air temperatures.

“This is genuinely pioneeringtechnology”, says Steve Wood, SalesManager, Core AC. “A consolidateddesign and the integration of newtechnologies have led to the mostefficient water cooler in the market,resulting in partial Power UsageEffectiveness (pPUE) of 1.08, lowerthan any other chilled water system.In addition, the Liebert AFC provides a significant increase in terms of

energy savings when compared withother efficient chilled water systemson the market.

“For example, in a typical 1.4 MWdata centre located in central Europerunning at full load, a free-coolingchiller will consume approximately963,000 kWh of energy per year,based on current market offerings.However, this is reduced to 645,000kWh over an annual period with theLiebert AFC. This reduction in energyconsumption equates to a cost savingof almost €50,000 based on anenergy cost of 0.15 €/kW.”

Emerson Network Power iscontinually striving to develop datacentre solutions for the future. Theseare designed to optimise availabilityto the customer in any circumstanceand this commitment was marked last year with the launch of its dedicated Thermal Management business. Drawing on the combined experience and industry-leading knowledge within the Thermal Management business, the Liebert AFC solution seeks to address

the complex requirements ofenterprise-scale and colocationfacilities, in order to reliably and efficiently control and manage heat.

“Over the last few years the data centre ecosystem has becomemission-critical in supporting majorinnovation trends such as cloudcomputing, the latent power of ‘bigdata’, and the exponential rise ofmobile devices”, says AustinMcDermott, Managing Director ofCore AC. “This, in turn, has made for an increase in operatingtemperatures within which ITinfrastructure functions.

“Our latest Liebert AFC adiabaticfree-cooling chiller seeks to addresssome of the evolving pressuresaround this growing requirement for heat management. Driven by our understanding of the challengesfacing our customers, we are adopting innovative methods –like the newly-introduced adiabaticcooling – to deliver pioneering datacentre solutions.”

Mark Kiely, Director, DWG RefrigerationWholesale said: “Trying to keep accuraterecords of cylinder holdings and productallocations using spreadsheet-based systems is challenging, and is always open to humanerror. However, with trackmycylinders.com, oneof the real benefits that our customers alreadysee is that it uses bar-coding technology andupdates automatically. This ensures thattransposition of cylinder numbers is totallyeradicated. It also assists in managing lostcylinder charges as these are clearly displayedwhen applicable.

“As well as showing users current cylinderholdings, the system allows the user to

allocate both cylinders and product on atransaction basis to the engineer, who canthen in turn allocate the location, the jobnumber, the refrigeration system in question,the product added to or removed from therefrigeration system, etc etc.

“With the implementation of the secondphase of the F-Gas Regulation from 1 January2015 and the need for clear, concise andaccurate record keeping, the value placed onhaving access to trackmycylinders.com reallyis immeasurable …all the information youneed is there at the touch of a button”.

All refrigerant cylinders require ahydrostatic pressure test every 10 years

under ADR Regulations. Under currentlegislation it is NOT illegal for a contractor orengineer to use a cylinder that has exceededits test requirements. Harp International hasa “duty of care” to notify users of its cylinderfleet that test dates have expired and wouldalways recommend that these cylinders arereturned for a new pressure test as soon asis practical. The system highlights this data.

When making a decision to specify,replace or upgrade refrigerationequipment, it is important to

remember that the system’s lifetime running costs are often several times greater than its initial purchase cost.

To illustrate this, Danfoss has developed a number of lifecycle software tools that compare

the energy usage of various

refrigeration condensing units so as to uncover the true cost of ownership.

By combining anticipated usage rate,energy cost per kWh and a few keypoints of data known to the equipmentmanufacturer, it is possible to producean analysis of costs within a product’slifecycle.

Stark differencesLifecycle calculation frequently showsthat over a given period, refrigerationequipment running costs can be severaltimes greater than the initialequipment purchase price. Incrediblethough it may seem, running costs arevery often overlooked in favour of asmall, short-term cost saving offered by a cheaper unit that consumesenergy at a much greater rate. Like-for-like comparisons often reveal starkdifferences in the energy consumptionand actual running costs.

For example, take two refrigerationcondensing units that are available to

achieve a desired cabinet or coldroomtemperature. Unit A is €200 cheaper topurchase and appears to be the bestoption. However, lifecycle calculationreveals that its energy consumption is500W per hour greater than the moreexpensive Unit B. In real terms, thistranslates to an additional €300 on the annual electricity bill when using Unit A.

As such, the initial €200 savingoffered by Unit A evaporates withinthe first year of use and it quicklybecomes a much more expensiveoption. Spending a little more to begin with on Unit B could potentiallysave the end user as much as €1,300 in energy costs over five years.

A contractor providing thisinformation offers greater support tothe customer and enables the end-user to make a much more informeddecision when planning to install newequipment or upgrade/replace agingequipment.

The installation of energy efficientequipment benefits us all but it doesnot have to come at a cost. Indeed,lifecycle calculation provides a greatdeal of evidence that by purchasing for the longer-term, large savings aremore than possible. Pressure faced onthe initial purchase price is reducedwhen energy consumption cost is given the proper consideration.

VALUE-SELLING THE WAYFORWARD


When it comes to refrigeration, and indeed to the entire building

services sector, understanding lifecycle cost profiling is

essential when specifying project solutions. While the initial

purchase price of new equipment is undoubtedly very important,

it is only a part of the story. Often what appears to be the

cheapest option is actually very far from it, writes Alex Williams,Commercial and Specification Consultant, Danfoss.

Improving effi ciency is a key focus of our development work. Our target is to increase pump performance while simultaneously decreasing the energy input. Thus a pump or system, e.g. as a replacement, can be sized signifi cantly smaller and yet be more effi cient.

“Perfectly coordinating performance and efficiency …… that’s what I call Pioneering for You.”Dr. Franka Schneider, Research Engineer Fluid Mechanics WILO SE
