Abstract: A refrigerator includes a first compressor configured to compress a first refrigerant, a first condenser configured to return the first refrigerant to the first compressor during a freezing cycle, a second compressor configured to compress a second refrigerant, and a second condenser configured to return the second refrigerant to the second compressor during a refrigerating cycle. The refrigerator includes a controller configured to control a radiating fan for the first condenser and the second condenser based on an operation state of the first compressor and the second compressor, and a refrigerant loop channel configured to allow the first refrigerant passing through a refrigerant channel that is located between a body and a door of the refrigerator. The refrigerant channel is coupled to the first condenser, and, for a predetermined time interval, an average operation time of the freezing cycle is longer than an average operation time of the refrigerating cycle.
