Abstract

According to the invention, the temperature and flow rate of cooling water for removing the heat of absorption are controlled artificially according to the cold output of load water by utilizing heated cooling water after the removal of the heat of absorption or heat source water, etc. According to the invention, a coolant tank and a load heat exchanger unit are provided as separate units. A load carrier is provided for cooling the load while partly evaporating the coolant through heat exchange between liquid coolant supplied from the coolant supplied from the coolant tank through a pump and the load. Mixture fluid of liquid coolant and vapor coolant after the heat exchange in the load cooler are returned to the coolant tank for separation of gas and liquid. Because the coolant tank and the load cooler are provided separately, the heat exchange with the load is performed by utilizing the latent heat of evaporation of coolant independently of possible temperature variations in the coolant tank. It is thus possible to obtain load heat at a constant temperature.
