PROBLEM TO BE SOLVED: To improve the energy saving effect of the subject system by improving the effective utilization factor of the quantity of heat storage in a heat storage type heat source system. SOLUTION: A heat source system using a heat storage tank is provided with primary side flow rate control means 18a, 18b and 18c, for adjusting the circulating flow rate q of a primary side heating medium w1 in a primary side circulating passage 1 based on the detected temperature td of a secondary side heating medium w2 flowing from a relay heat exchanger 6, and automatically adjusting the temperature td of the secondary side heating medium w2 flowing from the relay heat exchanger 6 to target cooling temperature tds. Excessive flow rate suppressing means 19a and 19b are provided for suppressing the increase of the circulating flow rate q of the primary side heating medium w1 in the primary side circulating passage 1 under the control of flow rate by the primary side flow rate control means 18a, 18b and 18c, when the detected temperature ta of the primary side heating medium w1 entering the relay heat exchanger 6 is higher than setting temperature tas. |
