REFRIGERATOR AND METHOD FOR CONTROLLING A REFRIGERATOR

摘要

A refrigerator and a method for controlling a refrigerator are provided. The refrigerator may include a pair of evaporators. When a switching valve operates, one blower fan may be maintained in operation for a predetermined period of time to more quickly collect a refrigerant, thereby realizing an efficient cycle operation.

主权项

1. A refrigerator, comprising:
a body in which a compressor and condenser are disposed, the body having a refrigerator compartment and a freezer compartment; a refrigerator compartment-side evaporator disposed in the refrigerator compartment to cool the refrigerator compartment; a refrigerator compartment-side blower fan to forcibly blow air to heat-exchange the refrigerator compartment-side evaporator with air within the refrigerator compartment; a refrigerator compartment temperature sensor disposed in the refrigerator compartment to measure an internal temperature of the refrigerator compartment; a freezer compartment-side evaporator disposed in the freezer compartment to cool the freezer compartment; a freezer compartment-side blower fan to forcibly blow air to heat-exchange the freezer compartment-side evaporator with air within the freezer compartment; a freezer compartment temperature sensor disposed in the freezer compartment to measure an internal temperature of the freezer compartment; a switching valve that communicates with an outlet of the condenser, the switching valve being branched into the refrigerator compartment-side evaporator and the freezer compartment-side evaporator to selectively supply the refrigerant into an inlet of the refrigerator compartment-side evaporator or the freezer compartment-side evaporator according to temperatures of the refrigerator compartment and the freezer compartment; and a controller connected to the refrigerator compartment temperature sensor, the freezer compartment temperature sensor, the switching valve, the refrigerator compartment-side blower fan, and the freezer compartment-side blower fan to control an operation of each of the refrigerator compartment temperature sensor, the freezer compartment temperature sensor, the switching valve, the refrigerator compartment-side blower fan, and the freezer compartment-side blower fan, wherein the operation of the refrigerator compartment-side blower fan stops after the refrigerator compartment-side blower fan additionally operates for a predetermined period of time when the switching valve is switched from a state in which the refrigerant is supplied into the freezer compartment-side evaporator from a state in which the refrigerant is supplied into the refrigerator compartment-side evaporator.
