IEA Heat Pump Programme 3

The International Energy Agency (IEA) acts as energy policy advisor or its 28member countries as they work or reliable, aordable, clean energy or

their citizens. Founded during the oil crisis o 1973-74, the IEA initially co-ordinatedmeasures addressing oil supply shortages. Since then, evolving energy markets havebrought new challenges. The IEA’s portolio now ocuses equally strongly on climatechange policies, market reorm, energy technology collaboration and outreach to therest o the world. Scenario analysis and roadmapping play a prominent part in thework o the IEA’s teams o close to 200 sta. Energy experts and statisticians rommember countries conduct a broad programme o energy research, data compila-tion, publishing and public dissemination o the latest energy policy analysis andgood-practice recommendations. Following up on work or the G8, initiated in 2005,the IEA was entrusted at the 2008 G8 Hokkaido Summit in Hokkaido, Japan, with asecond set o tasks or leaders o the world’s major industrialised nations.

For more than 30 years, IEA technology collaboration has been crucial in advanc-ing more ecient, cleaner energy technologies. The collaborative vehicles are IEAenergy technology R&D Programmes, or Implementing Agreements. These allowinterested member and non-member governments to pool resources or R&D anddeployment ocusing on particular technologies. Operating within the standardrules and regulations o the “IEA Framework”, these Implementing Agreement Pro-grammes currently number 42. They cover the areas o: End-Use (Buildings, Industryand Transport); Fossil Fuels, Renewable Energies and Hydrogen; Fusion and Cross-Cutting Activities. The IEA Committee on Energy Research and Technology (CERT)and its Working Parties provide guidance and review the eectiveness, achievementsand strategies o each Implementing Agreement.

This publication concerns the “Implementing Agreement or a Programme o Research, Development, Demonstration and Promotion o Heat Pumping Technolo- gies” , known as the IEA Heat Pump Programme (HPP).

Chairman’s Statement 2008

It is once again my great pleasure to write the Chairman’s Statement or the IEA HeatPump Programme. In its 30 years o existence, the Programme has ostered inorma-

tion exchange and dissemination on heat pumping technologies, and stimulated thedevelopment o advanced heat pump systems. It is a tribute to the excellent collabo-ration o all members that the Programme is now well established and recognised.So, on this 30 year anniversary o HPP, I would like to thank all members or theiractive and continuing participation. With increasing energy demand, heat pumps areeven more pertinent now than they were 30 years ago. We must continue our e-orts to acilitate the implementation o heat pump systems as a central componento ecient energy systems.

This year has been marked by the accession o two new member countries: SouthKorea and Italy. On behal o the Executive Committee, I am delighted to welcomethem. I am convinced that they will be major contributors to the development o theProgramme. Their presence will increase HPPs visibility and contribute to the Pro-gramme deployment in their respective countries.

The major event o the year was the 9th International Heat Pump Conerence heldin Zürich. In this report you can read more about how successul this conerence wasin terms o quality o conerence programme, number o participants and presenta-tions. A rst class organisation was a major reason or its success. All our congratula-tions go to the members o the National and International Organising Committeesor this event and particularly to Proessor Thomas Kopp and Dr Rune Aarlien whochaired these committees. During the conerence the Ritter von Rittinger award waspresented or the second time. Proessor Predrag Hrnjak (USA), Proessor Eric Gran-ryd (Sweden) and Mr Gerald Gro (USA) received the award or having distinguishedthemselves in the advancement applications in heat pumping technologies, marketdevelopment and related dissemination activities that provide lasting internationalimpact. Also, or the rst time two awards were presented or best posters at theconerence.

Two Executive Committee meetings were held, one in Zürich, in June and one inSeoul, in November. In conjunction with the Seoul meeting, a workshop was organ-ised by the Korean representatives to present their national heat pump activities andto obtain more inormation on the IEA Heat Pump Programme. HPP was also presentat other international events such as the IEA Building Coordination Group meetingin Paris in January and the Chillventa trade air in Nürnberg, Germany, in October,which was an opportunity to promote the Programme. HPP also holds regular meet-ings with the International Institute o Rerigeration and the European Heat PumpAssociation.

For the coming year, I would like to draw your attention to the portolio o excit-ing new topics or collaborative projects that are being developed. We anticipate

that they will materialise in new Annexes very soon. I encourage you to visit the HeatPump Centre website. You will learn all about our new activities and remain at theoreront o heat pump developments.

Finally, I would like to thank the Heat Pump Centre team or their exceptional sup-port to the Programme.

The 9th International Energy Agency Heat“Advances and Prospects in Technology, Applications and Markets”

The 2008 conerence was the ninth in a series o triennial conerences sponsored bythe International Energy Agency (IEA) Heat Pump Programme (HPP), and it attracted

450 attendees rom 34 dierent countries – the largest IEA Heat Pump Conerenceever staged. Experts rom research institutions, government, energy companies andmanuacturers provided 72 oral presentations and 106 poster presentations, whichalso included six technical tours. The conerence is one o the primary activities oHPP, and is recognised as one o the most important international conerences de-voted to air conditioning, heat pumps and related rerigeration technologies.

There are two primary objectives with these conerences. The rst is to give theaudience a snapshot o international developments within the eld o heat pumpingtechnologies over the last three years, and a sense o direction or uture trends. Thesecond is to create a orum that will spur new thoughts and ideas or internationalcooperation and more widespread deployment o heat pumps. In a world with grow-ing concerns over the global environment and the consequences o escalating energyuse, we know that heat pumping technologies play, and will continue to play, a vitaland important role.

Conference organisationThe International Organising Committee consisted o members rom nine dierentIEA HPP member countries. The Chairman was Dr Rune Aarlien rom Norway. TheSwiss National Organising Committee consisted o Proessor Thomas Kopp (Chair-man), Mr Stephan Peterhans, Mr Fabrice Rognon and Mrs Luzia Arpagaus. The Re-gional Coordinators, Dr Monica Axell (or Europe and Arica), Mr Makoto Tono (orAsia/Oceania) and Mr Gerald Gro (or America), were responsible or the coner-ence technical programme.

Highlights o 2008

RoadmapDuring spring 2008, HPC together with representatives rom member countries,

contributed with a roadmap or heat pumping technologies to the IEA Energy Tech-nology Perspectives 2008 publication. The results showed that heat pumps can havea large impact in abating GHG emissions, and is pointed out by the IEA as one o thekey technologies in the building sector or a better energy uture. These importantconclusions were also stressed by Dr Antonio Pfüger, Head o Energy TechnologyCollaboration Division in IEA, in a speech at the 9th IEA Heat Pump Conerence inZürich.

The IEA Energy Technology Perspectives 2008, which was issued in June, respondsto the G8 call on the IEA to provide guidance or decision makers on how to bridgethe gap between what is happening and what needs to be done in order to build aclean, clever and competitive energy uture.

The ndings in the report werediscussed in HPP where it is believed that better

statistics on heat pumps could, in act, improve the gures even more.

The brochure ”Heat pumps can cut global CO2

emissions by nearly8%”This brochure describes the potential and environmental benets o heat pumps. Itis estimated that heat pumps could save 50% o the building sector’s and 5% o theindustrial sector’s CO

2emissions. This corresponds to a cut in global CO

2emissions o

nearly 8%.The brochure is available ree o charge on www.heatpumpcentre.org

National Teams meeting in MalmöOn the 11-12th o September a National Teams meeting was held in Malmö, Sweden.24 participants, representing both member countries and industry, were present. Themain ocus o the meeting was to discuss and develop ideas or research projectswithin HPP.

The meeting began with the ten participating countries giving a short presenta-tion highlighting new research topics o interest in their country. The main part othe meeting was devoted to discussion and brainstorming in order to give the nalshape to a number o research ideas. The primary areas discussed were industrialheat pumps, ree cooling, domestic hot water heat pumps and seasonal perormanceactors.National Teams meeting in Malmö

Programme Achievements 2008

Heat Pump CentreThe Heat Pump Centre plays a central role in the IEA Heat Pump Programme. It aims

to disseminate actual and balanced inormation on heat pumping technologies andpromoting the activities o the Programme. The ExCo has approved an extensiono SP Technical Research Institute o Sweden’s mandate to manage the Centre until2011.

ActivitiesOne o the main activities is the publication o the Heat Pump Centre Newsletter.Each issue covers a particular topic and contains articles, news and events, togetherwith a contribution rom a guest columnist. Four issues were published in 2008,available ree o charge rom the HPC website to the HPP member countries. Non-member countries can subscribe to the Newsletter.

A short version o the Newsletter, an e-Newsletter, is available ree o charge to

all countries, either by e-mail subscription or by downloading rom the HPC web-site. The number o subscribers to the e-Newsletter increased by over 50% in 2008.In addition, the newsletter is also disseminated through the National Teams in themember countries.

The Heat Pump Centre also plays an active part in generating new activities withinHPP. For example, it publishes ongoing descriptions o project proposals on thewebsite in order to stimulate the initiation o new Annexes. HPC has also compileda report with inormation on research and development and market development inHPP member countries. The report is available to the National Teams in the membercountries.

Another important activity is the website, which is continuously updated withnews, events and contact inormation. Descriptions o ongoing and completed HPP

Annexes are also available on the website as well as HPP publications, which are ac-cessible via a data base. During 2008 the website was enhanced with two new sec-tions, one about the IEA Heat Pump Conerences and one about theRitter von Rittinger award.

One o the main activities o HPC in 2008 was the close involve-ment in the arrangement o the 9 th IEA Heat Pump Conerence heldin Zürich, Switzerland, in May.

Two other important activities o HPC during 2008 were the pro-duction o a roadmap or heat pumping technologies or the IEAEnergy Technology Perspectives 2008 publication and the productiono a brochure about the potential o heat pumps to signicantly cutglobal CO2 emissions.

In September, HPC arranged a National Teams meeting in Malmö,Sweden. The main ocus on the meeting was to discuss and developideas or research projects within the IEA Heat Pump Programme.

Participating countries: France, Germany (Operating Agent) and the Netherlands

The present heat pump market or space and water heating and cooling in Europe,with the exception o Sweden, is largely concentrated on new buildings, and particu-larly on one and two-amily houses. There is, however, a very large potential in theretrot market to replace old conventional oil-, gas- and coal-red heating systemswith highly energy-ecient and environmentally riendly heat pumps.

The main barrier to the use o heat pumps or retrotting is the high distributiontemperature o conventional heating systems in existing residential buildings, withdesign temperatures up to 70-90°C, which is too high or the present heat pumpgeneration or which the maximum, economically acceptable heat distribution tem-perature is up to 55°C.

The primary ocus o this Annex has been on domestic buildings. In order to reachthe goals o the Annex, solutions have been studied and experience gained on:• The application of available heat pumps in standard buildings that have been im-

proved, resulting in a reduced heat demand.• The development and market introduction of new, compact, high-temperature

heat pumps or application in existing buildings.• The use of reversible (heating-cooling) heat pumps (air-to-air) in buildings without

centralised heat distribution systems.To achieve this promising potential as quickly as possible, barriers need to be re-

moved or overcome. It is, or example, dicult to distinguish between dierent typeso heat pumps, to decide which type o heat pump best suits a particular application,and which requirements a building should ull. A chart has thereore been createdto simpliy the selection o heat pumps (see chart below).

The Annex was completed at the end o 2008. The last meeting, held in February2008 in Utrecht, the Netherlands, was thereore concentrated on nal discussionso the results achieved and preparation o the Annex report and related appendices,in particular the presentations o case studies and RD&D projects. Two public work-shops were organised in 2008, presenting the major ndings o the Annex as wellas new developments related to the objectives o the Annex in Germany, France, theNetherlands and Sweden. The workshops were held in connection with the 9th IEAHeat Pump Conerence in Zürich, Switzerland, in May, and the DKV InternationalHeat Pump Conerence at the Chillventa trade air in Nürnberg,Germany, in October.

As a result o this work, it is today clear that in many casesheat pumps already can, or will soon, be used as a preerableretrot choice. The use o heat pumps results in greatly im-

proved eciency o heat generation, reduction in use o ossilenergy and, at the same time, permits the choice o geother-mal, hydrothermal or aerothermal renewable energy sources.

The nal results o the Annex will be published in three re-ports, intended or dierent target groups: an executive sum-mary that will be public, a ull report with all details or internaluse o the participating organisations/companies, and specialreports or inormation to specic target groups, e.g. politicians,the heat pump industry and R&D organisations and sponsors.




Annex 31Advanced Modeling and Tools or Analysis o Energy Use in Supermarkets

Participating countries: Canada, Germany, Sweden (Operating Agent), UnitedKingdom (partly) and the United States

Supermarkets are the most energy-intensive buildings in the commercial sector. Ithas been estimated that 3-5% o the total use o electricity stems rom supermar-kets in industrialised countries. In addition, it is estimated that the annual rerigerantlosses may be as high as 15-30% o the total charge, thus making supermarketsthe second largest emission source ater mobile air conditioning, according to themost recent report rom the UN Intergovernmental Panel on Climate Change. Thesupermarket sector has thereore a signicant role to play, not only rom an energyconsumption point o view but also rom the point o view o the impact o reriger-ant leakage.

The overall objective o Annex 31 is to provide new knowledge, methods andtools or enhanced energy eciency o, and thereore reduced environmental impactrom, supermarkets. The aim is also to share ideas and best practices among partici-pating countries, as well as inormation on available tools or modelling and analysis,in order to urther improve supermarket rerigeration systems. The Annex builds onexperience and ndings rom Annex 26, “Advanced Supermarket Rerigeration/Heat Recovery Systems” .

In order to achieve the objectives o the Annex, the ollowing task-sharing activi-ties are planned:Task 1 Collection o available data rom dierent supermarkets (benchmarking)Task 2 Development o perormance indices or supermarketsTask 3 Development and validation o a model library or specic supermarket

equipmentTask 4 Development o whole-building simulation modelsTask 5 Comparison o the results obtained with the dierent whole-building simula-

tion models or selected case studiesTask 6 Future perspectives and possibilitiesTask 7 Deployment o the knowledge developed (indices, guidelines, papers, act

sheets)

Meetings and workshops that were organised during 2008 were:• Meeting at ASHRAE Winter Meeting, New York, US, in January• Internet-based meetings throughout the year

• Workshop at the 9th IEA Heat Pump Conerence in Zürich, Switzerland, in May

Annex 31 is now in the phase reerred to as Tasks 3, 4 and 5. A template toreport sub-models (Task 3) and whole supermarket systems (Task 4) has been

distributed and inormation on several whole system supermarket models hasbeen collected. Notable here is a rich description o the supermarket modules toenergy plus (US contribution). Another initiative is the supermarket module orRETScreen® sotware developed by Natural Resources Canada.

A year prolongation o the Annex has been granted. This means that evalua-tion and validation o proposed supermarket models will start in 2009. Work onTasks 6 and 7 and nal report will start late spring 2009.

Annex 32Economical Heating and Cooling Systems or Low Energy Houses

Participating countries: Austria, Canada, Germany, France, Japan, the Netherlands,Norway, Sweden, Switzerland (Operating Agent) and the United States

Heat pumps are the only devices which can generate heating and cooling energy,even at the same time. Multiunctional heat pump systems or space heating, do-mestic hot water (DHW) production, ventilation and space cooling may thereore bea cost-eective means o meeting all building needs with one integrated system.

The aim o this Annex is to investigate dierent system congurations o heatpump systems, including the respective energy source and distribution systems, orapplication in low- and ultra-low-energy buildings. The principal objectives are:• to improve and further develop multifunctional heat pump systems in terms of

overall energy use, achievable comort and costs,• to gather more eld experience from real-world operation of heat pump systems,

and• to derive design guidelines for multifunctional heat pump systems and their con-

trol.

The Annex has been structured into our tasks:Task 1 State-o-the-art survey o low-energy buildings and respective systemsTask 2 Assessment o system solutions and development o prototype systemsTask 3 Field testing o systems (in parallel with Task 2)Task 4 Develop guidelines or systems and their control and document best-practice

systemsThe Annex started in January 2006, and has been extended to a our-year working

period, and will nish at the end o 2009. In the beginning o 2008, the Annex 32website was launched, which gives an outline o the national project contributionsand oers national heat pump links o the participating countries as well as down-loadable publications.

Activities in 2008 were dedicated to the work o Task 2, the investigation andassessment o prototype systems, and Task 3, the eld monitoring o present sys-tems on the market and new developments. Interim results o these tasks werepresented on a workshop in conjunction with the 9th IEA Heat Pump Conerence inZürich, Switzerland, in May. Ater the conerence France joined Annex 32 as the 10th member country. France is represented by Electricité de France (EdF) and will mainlyinvestigate economical air-to-air heat pump solutionsor low energy houses. The results have been sum-marised in an interim report o Annex 32 or the HPPExCo, which was published in November.

Main activities in the national projects are dedi-

Annex 33Compact Heat Exchangers in Heat Pumping Equipment

16

Participating countries: Austria, Japan, Sweden, United Kingdom (OperatingAgent) and the United States

This Annex is directed at widening the use o compact heat exchangers (CHEs) inheat pumping systems. It is believed that these will improve eciencies, minimisefuid inventories and reduce package size. The data collected during the Annex will,it is hoped, quantiy the possible benets rom CHE use, and also highlight any con-cerns. Ultimately, the use o compact heat exchangers should signicantly improvethe acceptability o heat pumps across all applications, by allowing improved COPsand reduced materials content.

The principal objective o this Annex is to present a compilation o possible optionsor compact heat exchangers, used as evaporators, condensers and in other roles inheat pumping equipment. The aim is to minimise the direct and indirect eect on thelocal and global environment due to manuacture operation and nal disposal o theequipment.

Specic technical goals involve identiying and documenting reasonably accuratemethods o predicting heat transer, pressure drop and void ractions in CHEs, there-by promoting their commercial use by heat pump manuacturers by simpliying thedesign and selection procedures. Integral with these activities will be an examinationo maniolding/fow distribution in compact/micro-heat exchangers, in particular inevaporators.

During 2008, Austria (represented by Arsenal Research) joinedthe Annex, bringing the number o participants to ve.

The Annex meeting in 2008 was held at the 9th IEA Heat PumpConerence in Zürich, Switzerland, in May, and was in the orm oan open workshop at which presentations by the Annex memberswere given. Included in the presentations was an overview oresearch on compact heat exchangers relevant to heat pumps byProessor Björn Palm, o the Royal Institute o Technology (KTH),Sweden. Typical o the new compact geometries being examinedor the application is the aluminium unit rom KTH shown in thegure.

In 2009, meetings are planned in Chicago (held in February) and in the UK(planned or September). This will be the nal Annex meeting.

As examples o work within the Annex, the air-side perormance o fat-tube heatexchangers, a conguration oering compactness, has been studied in the USA,as has super and near critical heat transer o R410A in small diameter tubes. InSweden, the use o natural rerigerants and hydrocarbons is o interest and KTH hasexamined the use o propane in systems involving compact plate evaporators and

condensers. Compact heat exchangers o other types, some commercially available,have been successully tested with CO

2 as the working fuid.In Japan, the compact heat pump water heater, using a novel heat exchanger de-

sign, has a large potential market and the Japanese team expects to deliver the ol-lowing: market trends o rerigeration and air-conditioning systems, a survey o R&Dneeds in heat exchangers, recent research on heat exchanger technology and recentdevelopment on heat exchanger technology.
