Abstract:
A refrigeration cycle apparatus (1A) includes: an evaporator (23) that retains a refrigerant liquid and that evaporates the refrigerant liquid therein; a condenser (22) that condenses a refrigerant vapor therein and that retains the refrigerant liquid; a vapor channel (2A) that is provided with a compressor (21) and that directs the refrigerant vapor from the evaporator (23) to the condenser (22); a liquid channel (2B) that directs the refrigerant liquid from the condenser (22) to the evaporator (23); a condensation-side circulation path (4) that allows the refrigerant liquid retained in the condenser (22) to circulate via a heat exchanger for heat release (41) and that is provided with a condensation-side pump (45) at a position upstream of the heat exchanger for heat release (41); and a back-flow path (7) that directs a portion of the refrigerant liquid flowing in a section downstream of the heat exchanger for heat release (41) in the condensation-side circulation path (4) to a section upstream of the condensation-side pump (41) in the condensation-side circulation path (4) or to a bottom of the condenser (22).
