TRI-HP (H2020) – Trigeneration systems based on heat pumps with natural refrigerants and multiple renewable sources

The overall goal of the TRI-HP project is the development and demonstration of flexible energy-efficient and affordable trigeneration systems. The systems will be based on electrically driven natural refrigerant heat pumps coupled with renewable electricity generators (PV), using cold (ice slurry), heat and electricity storages to provide heating, cooling and electricity to multi-family residential buildings with a self-consumed renewable share of 80 %. The innovations proposed will reduce the system cost by at least 10 - 15 % compared to current heat pump technologies with equivalent energetic performances. Two natural refrigerants with very low global warming potential, propane and carbon dioxide, will be used as working fluids.


The project is lead by SPF and supported by the research programme H2020 of the European Union – grant agreement ID: 814888
