During the work in Annex 34 “Thermally Driven Heat Pumps for Heating and Cooling” there was a rising interest in the area of fuel driven sorption heat pumps and more and more products came closer to market. Since we learned during the process of Annex 34 that the fields of solar thermal cooling and fuel driven heat pumping need different measures for a wider market penetration, there was a common understanding to continue this work in two different Annexes or Tasks.
Therefore, the work of Annex 34 regarding solar thermal cooling is continued within the IEA SHC Task 48 “Quality assurance and support measures for Solar Cooling” while for the continuation of the fuel driven heat pumps part a new Annex “Fuel driven sorption heat pumps” was proposed to the ExCo in March 2012. After an Annex definition meeting a legal text was compiled and as draft accepted by the Exco, so Annex 43 started officially in July 2013 with a duration of four years. A kick-off meeting was held on 9./10. October 2013 in Freiburg with participants from six countries. Main topics were the finalisation of the Legal Text and the work plan and setting up the organisational framework.
The scope of the work under this Annex will be the usage of fuel driven sorption heat pumps in domestic and small commercial or industrial buildings or applications. If applicable the additional possibility of supplying cold will also be considered. The main goal is to widen the use of fuel driven heat pumps by accelerating technical development and market readiness of the technology, as well as to identify market barriers and supporting measures. A field test and proposing performance evaluation figures and optimal system layouts are among the means of this Annex.
Task A: Generic systems and system classification
Task B: Technology transfer
Task C: Field test and performance evaluation
Task D: Market potential study and technology roadmap
Task E: Policy measures and recommendations, information
