A refrigerator having a refrigerator evaporator and a freezer evaporator, capable of controlling the refrigerant circulation correctly and reducing the delay in the refrigerant behaviors. When freezer mode is to be switched to refrigerator mode, at the end of the freezer mode, a refrigerant recovery run recovers the refrigerant from the freezer evaporator and feeds it to a condenser before the refrigerator mode by running a compressor while blocking the refrigerant to the freezer evaporator and by running a compressor fan.

1. A refrigerator comprising:a compressor and a condenser connected in the recited order; an evaporator for a refrigerator compartment and an evaporator for a freezer compartment both connected in parallel to the downstream side of the condenser, and a switching unit interposed between the condenser and the two evaporators for switching the passage for a refrigerant from the condenser, between the refrigerator compartment evaporator and the freezer compartment evaporator; and a condenser fan for cooling the condenser, a cold air circulation fan for the refrigerator compartment for blowing the cold wind of the refrigerator compartment evaporator to the refrigerator compartment, and a cold wind circulation fan for a freezer compartment for blowing the cold air of the freezer compartment evaporator to the freezer compartment, whereby a refrigerating run for cooling the refrigerator compartment by feeding the refrigerant to the refrigerator compartment evaporator and a freezing run for cooling the freezer compartment by feeding the refrigerant to the freezer compartment evaporator can be individually executed by switching the passage of the refrigerant by the switching unit, wherein at the end of the freezing run, a refrigerant recovery run for recovering the refrigerant from the refrigerator compartment evaporator and feeding it to the condenser is performed by running the compressor while blocking the refrigerant to flow tot he freezer compartment evaporator with the switching unit and by running the condenser fan; and wherein after the temperature of the freezer compartment evaporator reaches a predetermined level after starting of the refrigerant recovery run, the refrigerating run is performed by switching the switching unit to feed the refrigerant only to the refrigerator compartment evaporator.
