<P>PROBLEM TO BE SOLVED: To provide a refrigeration cycle apparatus that improves heating ability and efficiency by quickly achieving a proper refrigeration cycle state. <P>SOLUTION: The refrigeration cycle apparatus includes a first temperature sensor 61 for detecting a temperature of a refrigerant flowing out from a supercooling heat exchanger 23, a first saturation temperature detection means 51 for detecting a saturation temperature of the refrigerant sucked into a compressor 21, a second temperature sensor 62 for detecting the temperature of the refrigerant flowing out from a radiator 22, and a second saturation temperature detection means 52 for detecting the saturation temperature of the refrigerant of the radiator 22. When the detection temperature of the first temperature sensor 61 is higher than the detection temperature of the first saturation temperature detection means 51, a bypass expansion means 31 is actuated so that the detection temperature of the first temperature sensor 61 gets close to the detection temperature of the first saturation temperature detection means 51. When it is substantially the same, the bypass expansion means 31 is actuated so that the detection temperature of the second temperature sensor 62 becomes lower than the detection temperature of the second saturation temperature detection means 52 by a predetermined temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
