TRI-HP

The TRI-HP systems are based on electrically driven natural refrigerant heat pumps coupled with renewable electricity generators (PV), and are using cold (ice slurry), heat and electricity storages. They will be providing heating, cooling and electricity to multi-family residential buildings with a self-consumed renewable share of 80%. Two system concepts are developed for two different combinations of heat sources: i) dual ground/air source and ii) solar with ice-slurry as intermediate storage. These concepts combined with the developed heat pump types (carbon dioxide and propane) will lead to three complete systems (CO2-ice, propane-ice and propane-dual) that will be tested at the laboratory scale.
