摘要
A heat-pump refrigeration cycle is constructed using a compressor, a four-way valve, a water heat exchanger, a receiver, and air heat exchangers. The compressor draws in, compresses, and discharges refrigerant. The four-way valve switches a direction of refrigerant flow, and a water heat exchanger allows an exchange of heat between inflow refrigerant and water supplied from a water supply unit. The receiver stores liquefied refrigerant, and a parallel circuit of a plurality of air heat exchangers allows an exchange of heat between the inflow refrigerant and indoor air. The water heat exchangers are positioned at a location higher than the receiver, which, during the cooling operation, permits liquefied refrigerant generated at the water heat exchanger to run down into the receiver. This prevents the refrigerant from remaining in the water heat exchangers.
