Japanese Patent JP5328713

B2

There is provided a refrigeration cycle apparatus in which refrigerating machine oil is reliably returned to a compressor, regardless of whether the refrigerating machine oil is miscible or immiscible with a refrigerant. A refrigeration cycle apparatus 1010 includes a first refrigerant channel in which a compressor 101, a condenser 103, a first flow control valve 104, a refrigerant storing container 105, a second flow control valve 106, and a first evaporator 107 are connected in that order with pipes and in which a refrigerant outlet of the first evaporator 107 is connected to a suction refrigerant inlet 1092 of an ejector 109 with a pipe; a second refrigerant channel in which a compressor 101 and a second evaporator 110 are connected in that order with a pipe and in which a refrigerant inlet of the second evaporator 110 is connected to a mixed refrigerant outlet 1093 of the ejector 109 with a pipe; and a third refrigerant channel branching off from a halfway point of the pipe connecting a refrigerant outlet of the radiator 103 and the first flow control valve 104 and in which a third flow control valve 108 and a motive refrigerant inlet 1091 of the ejector 109 are connected in that order with a pipe.
