REFRIGERATION CYCLE APPARATUS

摘要

A refrigerant circuit is configured so as to allow a refrigerant output side of an outdoor heat exchanger (17) to communicate with a heating-side refrigerant suction port (15d) of a heating-side ejector (15), which serves as a refrigerant pressure reduction means, and to allow the refrigerant input-side of an indoor evaporator (23) to communicate with the output side of a heating-side diffuser (15g) of the heating-side ejector (15), in a dehumidification and heating mode. The refrigerant evaporation temperature in the outdoor heat exchanger (17) is reduced below the refrigerant evaporation temperature in the indoor evaporator (23) by the pressure-increasing action of the heating-side ejector (15). The amount of refrigerant heat absorbed in the outdoor heat exchanger (17) is thus increased, improving the heating capacity of air in an indoor condenser (12).
