ABSTRACT:
A direct cooling type refrigerator capable of rapidly and accurately controlling the temperature thereof, reducing the ON/OFF time of its compressor, thereby preventing the temperature deviation of its storage compartment from increasing over a predetermined value. The refrigerator includes an outer casing defining an appearance of the refrigerator, an inner casing arranged within the outer casing, and defined with a storage compartment, an insulator interposed between the outer casing and the inner casing, a compressor for compressing a refrigerant, an evaporator arranged to be in contact with the inner casing, and adapted to cool the inner casing in accordance with evaporation of a refrigerant passing therethrough, a temperature sensor provided with a surface contact area closely contacting the inner casing, and adapted to sense a temperature of the inner casing, and a control unit for controlling the compressor in accordance with the temperature sensed by the temperature sensor.
