04/2005   IEA HPP Annex 28 approach for calculation method in public enquiry
The approach of IEA HPP Annex 28 for the calculation of the energy performance of heat pump system has been implemented in the European draft standard prEN14335, which has been sent out for public enquiry in the beginning of April 2005. Final results will be included during the six-month period of public enquiry. The prEN 14335 is to come into operation in January 2006.

 

03/2005   Fourth working meeting of IEA HPP Annex 28 in Vienna
The 4th working meeting of IEA HPP Annex 28 took place at Arsenal Research in Vienna, Austria on March, 7-9 2005. The principal topic was the presentation and discussion of final results on Task 2 and Task 3 of the national projects. Furthermore, final decisions on the test procedure and the calculation method have been made and the planning of the presentation of of the final result on a workshop in the framework of the 8th IEA Heat Pump Conference in May 2005 has been accomplished.
In connection to the meeting a technical tour to the STRABAG builiding, an office building, that is supplied by a heat pump for heating and cooling the RTA test rig for trains and trucks, which is the largest in Europe.

 

02/2005   Convenor of CEN/TC 113/WG 10 appointed
Mr M. Nani, the head of the Swiss national test centre WPZ at NTH Buchs, has been appointed as Convenor of the Working Group 10 of the CEN Technical Committee 113 which is committed to the testing of heat pump systems.
Subject of the WG 10 is the revision of the EN 255-3 on the testing of heat pumps for sanitary hot water production. The working group will take up work in the near future. Results of the IEA HPP Annex 28 will be presented as recommendations for the further discussion of this working group as members of the national teams of the IEA HPP Annex 28 are participating in this CEN Working group, as well.

 

12/2004   Workshop for presentation of final result at IEA Heat pump Conference
The final results of the IEA HPP Annex 28 will be presented on a workshop in the framework of the 8th IEA Heat Pump conference 2005, which will take place in Las Vegas from May, 30 to June, 2 2005. The workshop is schedule for

Monday, May, 30 2005 from 8.30 am to 12.30 pm.

More details are given in the invitation leaflet available for download.
 
    UK has to withdraw IEA HPP Annex 28 participation
Due to problems with funding the UK, represented by the company Kensaengineering Ltd., had to withdraw the participation in IEA HPP Annex 28.

 

09/2004   CEN/TC 113/WG 10 postponed indefinitely
CEN/TC 113/WG 10 committed to revising the EN 255-3 standard on testing of heat pumps for domestic hot water production has been postponed indefinitely due to the lack of a convenor, unless a candidate for the convenor comes up. Hence, CEN will probably withdraw the work item from the working programme. However, the committee can decide at a given moment the new creation of this work item.

 

    CEN management centre approved EU - Mandate M/324
The EU mandate M/324 for “elaboration and adoption of measurement standards for household appliances: Water heaters, hot water storage appliances and water heating systems” to CEN/CENELEC, which was first rejected, has now been approved by the member states. The aim of the mandate was to revise product measurement standards to deliver comparable test results for different kind of domestic hot water generation systems to enhance the market transparancy and promote environment-friendly technologies in this sector by labelling.
Even though all member states basically agree on the necessity of this objective, some comments came up in the voting process, that the suggested tapping profiles are too complex and will produce inacceptably high costs. Moreover, since the subject is comprehensive and different TC are concerned, the need for harmonisation is expressed to come to a fair assessment of the different technologies of domestic hot water production in focus.

Third working meeting of IEA HPP Annex 28 held in Yokohama
The third working meeting of IEA HPP Annex 28 has taken place at TEPCO R&D Centre in Yokohama, Japan. The principal topic was the presentation and discussion of interim results on Task 2 and Task 3 of the national projects. Further on the time schedule has been adapted to the actual project state.
The meeting was embedded in a 3-day program, which contained as well a technical tour to the Japanese manufacturer SANYO and a Workshop, where the numerous members of the Japanese national team and the participants of the IEA Annex 28 could present their work. The papers of the workshop are available for download in the category “Publications”.

 

04/2004   EN 14511 for the testing of heat pump accepted in formal vote
The EN 14511 elaborated in the CEN/TC 113/WG 8 has passed the formal vote. The standard will replace the former standards EN 255-2 for the testing of heat pumps in heating mode, EN 814 and EN 12055 for the testing of the heat pumps in cooling mode. In comparison to EN 255-2 new testing points are introduced in the standard.
Actually comments received during formal vote are integrated in the standard. Probably the standard will be implemented on the national level by 2005.

 

    CEN management centre does not accept EU - Mandate M/324
The EU mandate M/324 for “elaboration and adoption of measurement standards for household appliances: Water heaters, hot water storage appliances and water heating systems” to CEN/CENELEC has not been accepted. The aim of the mandate was to revise product measurement standards to deliver comparable test results for different kind of domestic hot water generation systems to enhance the market transparancy in the sector and promote environment-friendly technology in this sector by labelling. However, the opinion on the mandate are quite controversal. Some countries basically agree with the mandate, but like to introduce amendments. Moreover, some of the product working groups of CEN already apply the tapping profiles contained in the mandate for the revision of the respective testing standards of water heating systems. However, with the refusal of the mandate, currently no general guideline for the unification of the testing of different systems exist.

IEA HPP Annex 28 interim report
An Interim Report on the IEA HPP Annex 28 has been delivered to the Executive Committee of the IEA Heat Pump Programme. The Report gives an introduction to the framework of the IEA HPP Annex 28, i.e. the project structure, the participating countries and the national projects. Main issues are the results of Task 1, the systems analysis, the State of the Art in standardisation as well as the boundary conditions for the calculation. Decision made on the second meeting of the IEA HPP Annex 28 held in October and first results of the national projects for Task 2 and Task 3 are treated, too.

New IEA HPP Annex 28 launched in 2003
The new IEA HPP Annex 2003 started it work with 10 countries (AT, CA, CH, DE, FR, JP, NO, SE, UK, USA), who declared their interest to participate. It is the first new Annex in the IEA Heat pump Programme after a period of four years. The Annex was initiated by Switzerland, which has the lead in the Annex, the so-called operating agent, as well. The Annex 28 is entitled “Test procedure and seasonal performance calculation of residential heat pump with combined space heating and domestic hot water production”. Objectives are comprehensive test procedures as basis for easy-to-use calculation methods for the seasonal performance of different types of combined working heat pumps.
