The present invention relates to a refrigerator system including a refrigerator configured to circulate a refrigerant through a compressor, a condenser, an expansion device, and an evaporator; a brine circulation pipeline through which a brine heat exchanged with the evaporator of the refrigerant to cool the load circulates; a cooling water pipeline circulating the cooling water heat exchanged with the condenser of the refrigerator as an external cooling heat source; and an auxiliary heat exchanger heat exchanging the cooling water branched from the cooling water pipeline between the external cooling heat source and the refrigerator with a heating fluid fed from the exterior. Therefore, the stability and the durability of the refrigerator system are improved by preventing the external cooling heat source from being overloaded, and the operational costs of hot water supply is reduced since waste heat is used as the preheat source for the hot water supply. |
