PROBLEM TO BE SOLVED: To provide a thermal storage tank, perform preferentially an operation at an operation region where a heat source system COP ratio is increased, store surplus heat manufactured in this case in the thermal storage tank in advance, and after thermal storage action, a heat radiation operation for the storage heat is repeated to attain an energy saving under a high efficiency.SOLUTION: A thermal storage tank 14 is installed at an intermediate part of the first bypass 13 in the prior art heat source facility 1, the first three-way control valve 15 is installed at an upstream side of the thermal storage tank 14 and there is provided the second bypass 16 for connecting the first three-way control valve 15 with a downstream side of the thermal storage tank 14, and there is provided a thermometer 17 for measuring a temperature of thermal medium flowing into the thermal storage tank 14. An operation at an operation region where a heat source system COP rate is increased is preferentially carried out, the surplus heat manufactured at this time is stored in advance in the thermal storage tank 14 and after heat storage, a heat radiation operation for the stored heat is repeated.SELECTED DRAWING: Figure 1 |
