Hot water supply air conditioner

摘要

There is provided a novel hot water supply air conditioner in which a hot water supply system and a cooling and heating system share outdoor equipment. The hot water supply air conditioner (1a) includes a first refrigerant pipe (L1) through which a refrigerant discharged from a compressor (15) flows, and a second refrigerant pipe (L2) through which the refrigerant flows toward an electronic expansion valve (19). The first refrigerant pipe (L1) is divided into a first branch pipe (L11) through which the refrigerant flows toward an indoor heat exchanger (31), and a second branch pipe (L12) through which the refrigerant flows toward a water/refrigerant heat exchanger (21). A third branch pipe (L21) through which the refrigerant flows from the indoor heat exchanger (31) toward the electronic expansion valve (19) and a fourth branch pipe (L22) through which the refrigerant flows from the third heat exchanger toward the expansion valve merge into the second refrigerant pipe (L2).
