摘要：

Operational tests of an air-to-water heat pump in a monoblock version with the natural refrigerant R290 (propane) were presented. The effect of temp. and variable mass flow of water in the evaporator circuit and variable heat load of the condenser on the selection of electronic expansion valve settings and the cooling power of the heat pump was discussed. Tests were carried out for the heat pump in the cooling mode of a laboratory room, in 60-minute measurement cycles. For the full heat load, an av. COP of 2.20 was obtained for the entire system.
