A refrigeration cycle apparatus includes a first refrigerant circuit connecting a refrigerant discharging part of a compressor 101, a condenser 102, a first expansion valve 103, a first evaporator 104, and a refrigerant suction portion 205 of an ejector 105; a second refrigerant circuit branching off from connection piping between an outlet side of the condenser 102 and the first expansion valve 103 and connecting to a refrigerant inflow portion 204 of the ejector 105; and a third refrigerant circuit connecting to a diffuser (a refrigerant outflow portion) 203 of the ejector 105, a second evaporator 106, and a refrigerant suction portion of the compressor 101. Each of the first evaporator 104 and the second evaporator 106 is a water heat exchanger to exchange heat between refrigerant flowing in a refrigerant circuit including the evaporator and a liquid heat medium different from the refrigerant. The liquid heat medium is supplied from outside, and flows out through the second evaporator 106 and the first evaporator 104 in this order. |
