文摘

CO2 and propane heat pumps for sanitary hot water production are modelled and sized. Their COPs and heating capacities are compared in different climates. A TRNSYS model with a realistic hospital and school load profile is simulated. Propane unit's seasonal performance factor is higher in warm and average climates. Control logic of these systems has a significant impact on energy performance.
