Abstract

A refrigeration cycle apparatus includes a second bypass pipe 13 and control means 16, one end of the second bypass pipe 13 is connected to a portion of the pipe extending from the supercooling heat exchanger 8 to the decompressing means 6, the other end of the second bypass pipe 13 is connected to a portion of the pipe extending from the evaporator 7 to the compressor 3, second flow rate adjusting means is connected to the second bypass pipe 13, the second bypass pipe 13 does not exchange heat of a refrigerant which flows out from the second flow rate adjusting means with heat of a refrigerant flowing through the supercooling heat exchanger 8, the first flow rate adjusting means and the second flow rate adjusting means are operated by a temperature detected by the control means by means of the temperature sensor 15, and the refrigeration cycle apparatus swiftly suppress the abrupt discharge temperature rise while maintaining a stable operation of the refrigeration cycle.
