  • Cooling apparatus and control method thereof
    Patent number: 9970700
    Abstract: A cooling apparatus includes a storage compartment, an evaporator to cool air in the storage compartment by evaporating a refrigerant, a compressor to compress the refrigerant evaporated by the evaporator, an air blower to supply the air cooled by the evaporator to the storage compartment and to remove frost formed on the evaporator, a storage temperature sensor to sense a temperature of the storage compartment, a driving unit to drive the compressor and the air blower, and a controller to perform a defrosting operation of operating the air blower to remove frost formed on the evaporator when a cooling operation of cooling the storage compartment is terminated and to perform the cooling operation, wherein the controller defers, when the defrosting operation is being performed, operation of the compressor, even if the temperature of the storage compartment is greater than or equal to the storage upper limit temperature.
