Abstract (en)
The present invention provides a refrigeration cycle apparatus 1A. When a temperature detected by the first temperature sensor 61 is higher than a temperature detected by the first saturation temperature detecting means 51, a control device 4 operates bypass expansion means 31 such that the temperature detected by the first temperature sensor 61 comes close to the temperature detected by the first saturation temperature detecting means 51. If the temperature detected by the first temperature sensor 61 is substantially equal to the temperature detected by the first saturation temperature detecting means 51, the control device 4 operates the bypass expansion means 31 such that a temperature detected by the second temperature sensor 6 becomes lower than a temperature detected by the second saturation temperature detecting means 52 by a predetermined temperature. Therefore, it is possible to enhance the heating ability and efficiency of the refrigeration cycle apparatus 1A.
