Abstract: A refrigerator is provided. The refrigerator may include a body having storage chambers formed therein, and a compressor, a condenser, an expansion device, and an evaporator that form a refrigerating cycle to cool the storage chambers. The condenser may include a refrigerant condensation channel through which refrigerant from the compressor passes and a working fluid evaporation channel through which working fluid is evaporated due to heat exchange with the refrigerant passing through the refrigerant condensation channel. The condenser may be connected with a hot line, through which the working fluid evaporated through the working fluid evaporation channel flows and discharges heat to reduce condensation.
