PROBLEM TO BE SOLVED: To increase the cooling performance right after the starting of a compressor for a refrigeration cycle device which adjusts the flow rate of a circulating refrigerant by adjusting the amount of a liquid refrigerant residing in a gas-liquid separator on the high pressure side, in response to an overheating degree of the refrigerant discharged from the compressor. SOLUTION: This refrigeration cycle device is equipped with a gas-liquid separator 7 which separates a gas and a liquid in the refrigerant on the high pressure side in the cycle, and a first by-pass passage 33 which adjusts the amount of the liquid refrigerant residing in the gas-liquid separator 7 by a variation of an overheating degree of the refrigerant discharged from the compressor 1. As the overheating degree of the refrigerant discharged from compressor increases, the amount of the liquid refrigerant in the gas-liquid separator 7 is reduced, and thus, the flow rate of the circulating refrigerant in the cycle is increased. When the compressor 1 is started, an electric fan 50 for cooling of a condenser 2 is fixed under a low speed rotation state by a controlling device 52. COPYRIGHT: (C)2003,JPO
