A refrigerator has a two-stage compressor and means for switching refrigerant flow between a primary channel and a bypassing channel at downstream of a condenser that is connected with an outlet of the two-stage compressor. The primary channel extends from a first exit of the means for switching, through a first capillary tube and a first evaporator, to a gas-liquid separator, a gas-exit of which is connected with a second evaporator through a second capillary tube. The bypassing channel extends from a second exit of the means for switching, through a bypass capillary, to the gas-liquid separator. When flow of refrigerant in the second evaporator is substantially interrupted and so detected, refrigerant flow is switched to the bypassing channel, by means for controlling.
