Projects

HPT TCP has been active since 1978, with a lot of collaborative research, development, demonstration and deployment projects. We formerly called these projects "Annexes". They are conducted on a combination of cost sharing and task-sharing basis by the participating countries. Here you can read about the projects that are running right now.

Working Fluid Safety

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 aspects of working fluids. Many of the environmentally acceptable alternatives are toxic or flammable (or both). Annex 20 carried out an international study (entitled Working Fluid Safety) in five countries. This objective and scientific study provided a valuable insight into the risks associated with using refrigerants. The results play...

Thermophysical Properties of Environmentally Acceptable Refrigerants

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 this project – Annex 18 – entitled: Thermo Physical Properties of Environmentally Acceptable Refrigerants, and was an international study of refrigerant properties. The project made an important contribution by carrying out an international study into the thermo physical properties of the leading contenders. The information generated was used...
