TEMPERATURE CONTROLLER AND TEMPERATURE CONTROL METHOD OF REFRIGERATOR WHICH IMPROVES THE EFFICIENCY OF THE COOLING SYSTEM BY MAINTAINING CAVITY OF REFRIGERATOR IN THE CONSTANT LOW TEMPERATURE STATE

摘要

PURPOSE: A temperature control apparatus of a refrigerator and a temperature control method of refrigerator are provided to lower the temperature of compressor rapidly since the location of the cooling fan is varied on the compressor. ;CONSTITUTION: The temperature controller of refrigerator includes: a sensor device(30); a cooling fan(23); an position changing unit(24); and a controller(40). A temperature sensor unit(31) of the sensor device senses the temperature of the compressor(21). The cooling fan cools the compressor by blowing air to the compressor. The position changing unit changes the location of the cooling fan on the compressor. The controller determines the location of the cooling fan according to the measurement value and transfer the operation signal to the position changing unit. The controller transfers the cooling fan closely to the compressor if the temperature measured at in sensor-device exceeds the set reference value.;COPYRIGHT KIPO 2011
