Abstract: A refrigeration cycle of a refrigerator includes a first refrigeration cycle in which a first refrigerant flows along a first refrigerant tube and a second refrigeration cycle in which a second refrigerant flows along a second refrigerant tube. First and second compressors compress each of the first and second refrigerants, and a combined condenser condenses each of the first and second refrigerants. First and second expansion valves phase-change each of the first and second refrigerants passing through the combined condenser, and first and second evaporators change the refrigerant passing through each of the first and second expansion valves into a low-temperature low-pressure gaseous refrigerant.

Abstract: Provided is a refrigerator, which includes a main body, a door, an evaporator, a defrosting heater, a defrosting sensor, and a control part. The main body includes a food storage space and an evaporation compartment. The door selectively closes the food storage space. The evaporator is disposed in the evaporation compartment. The defrosting heater is disposed at a side of the evaporator to remove frost from an outer surface of the evaporation compartment or the evaporator. The defrosting sensor is disposed at a side of the evaporation compartment or the evaporator to sense a frost formation amount. The control part receives a sensed value transmitted from the defrosting sensor, and controls an operation of the defrosting heater according to the sensed value. A sensing period of the defrosting sensor is varied according to a frost formation amount sensed by the defrosting sensor.

Abstract: A control method for a refrigerator includes sensing a temperature of a storage room; operating a cool air supply at a cooling power when the sensed temperature of the storage room is equal to or above a first reference temperature; operating the cool air supply at a delay power, which is less than the cooling power, when the sensed temperature of the storage room is equal to or below a second reference temperature, which is less than the first reference temperature while the cool air supply is operating at the cooling power; and adjusting the cooling power or the delay power of the cool air supply according to the temperature of the storage room while the cool air supply is operating at the delay power, and operating the cool air supply at the determined adjusted cooling power or delay power.
