Abstract
A refrigerator includes: (i) a compressor; (ii) a condenser; (iii) a decompressor; (iv) an evaporator; (v) a first pipe that connects the compressor, the condenser, the decompressor, and the evaporator, and that circulates a refrigerant therein; (vi) a second pipe that causes the refrigerant to circulate from the condenser to the evaporator; and (vii) a switching valve that switches flow of the refrigerant in the first pipe to the second pipe. A method for controlling the refrigerator includes: conducting a normal cooling operation in which a refrigerant is caused to circulate through a compressor, a condenser, decompressor, and an evaporator; and conducting a defrosting operation in which the refrigerant is caused to circulate through the compressor, the condenser, and the evaporator, excluding the decompressor.
