HPT TCP has been active since 1978, with a lot of collaborative research, development, demonstration and deployment projects. We call these projects "Annexes" and they are conducted on a combination of cost sharing and task-sharing basis by the participating countries. Here you can read about the finalized projects, from 1989 to this present date.
The Annex investigated the testing of the most common combined heat pump systems with heating of domestic hot water by desuperheating subcooling of the condensate cascade…
This project focused solely on CO2 as a working fluid in compression systems. The main objective was to bring CO2 heat pumping technology closer to commercialisation, by…
This project investigated candidate advanced system design approaches to determine their potential for reducing refrigerant usage and energy consumption for both refriger…
This project aimed to define and demonstrate the technical feasibility of new packaged systems for year-round residential space conditioning using heat pumps. The work in…
This project, which was concluded in June 1999, aimed to analyse the reasons behind the still limited implementation of absorption technology in heating and cooling. Part…
While heat pumps are sold in increasing numbers in many regions, installations are restricted to certain building types. In particular, relatively few heat pumps are inst…
Most of the substances being considered to replace chlorofluorocarbons (CFCs) and HCFCs as working fluids in heat pumping (heat pump, air conditioning and refrigeration) …
By upgrading heat at a lower temperature, industrial heat pumps use their high-energy efficiency to meet heating needs in industry, therefore helping to reduce the consum…
The need to find alternatives to the CFCs and HCFCs used in today’s heating, air-conditioning and refrigeration equipment has led to intensified interest in the safety as…
The phasing out of CFCs and HCFCs has led to a global quest to find alternative refrigerants for heat pumping equipment. Therefore the IEA Heat Pump Programme started thi…
