The EU project TRI-HP is aiming at developing trigeneration integrated solutions that provide heating, cooling and electricity by means of PV-coupled natural refrigerant heat pumps using multiple renewable energy sources. Within the TRI-HP project, three kinds of heat pumps have been developed. One is the so-called dual source/sink heat pump, featuring two potential heat sources and sinks using propane as a refrigerant (R290-dual). These two sources are brine from a ground probe eld and ambient air. The other two heat pumps use a water source that can be supercooled to produce ice slurry but employ different refrigerants: one uses propane (R290-ice), while the other uses CO2 (R744-ice) with a transcritical cycle. R290-ice and R744-ice use solar thermal collectors as heat sources for the evaporator in a concept known as solar-ice. This deliverable presents the fitting of simple quadratic model functions to experimental and simulated data of the three types of heat pumps investigated in the current project. These model functions allow a runtime efcient integration of these heat pump types into transient system simulations. The simplified heat pump models have been integrated into TRNSYS using pyrosis 1 and will be used to study the energetic and cost efficiency of these heat pump systems coupled with photovoltaics around Europe.
