PROBLEM TO BE SOLVED: To provide a cold heat supply device which prevents heat exchange between heat generated in a condenser and outer air to prevent emission of heat into atmospheric air.SOLUTION: A cold heat supply device comprises: a heat generation circuit 18; a cold heat generation circuit 12; an operation medium circulation passage 2 connecting the heat generation circuit with the cold heat generation circuit; an underground heat exchanger 20 for heat radiation which is buried in ground 29; a heat radiation side circulation passage 23 which connects the heat generation circuit with the underground heat exchanger for heat radiation to flow a heat radiation medium therein. The cold heat supply device is formed so as to transmit heat generated in a condenser 5 at the heat generation circuit from the underground heat exchanger for heat radiation to the ground.SELECTED DRAWING: Figure 1 |
