ている。However, in the above conventional district heating and cooling system, it is difficult to balance the flow rate between the supply pipe 7 and the return pipe 8 connected by an open circuit, which leads to an accident such as drought or overflow in the heat storage tank 2. There is a possibility that there is a possibility that the heat exchanger 9 is provided for each heat storage tank 2, but there is a problem that the space and cost are increased. In addition, when the heat is stored at night, the temperature inside the supply pipe 7 on the heat source device 6 side must be lowered to about 4 ° C. in the case of cold water,
The target cold water of 7 ° C cannot be obtained on the side of the heat storage tank 2,
There is a problem that the operating efficiency of the heat source device is significantly reduced.

水事故を防止することができる。The operation of the present invention having the above structure will be described for the case of supplying cold water. The cold water produced by the heat source device 6 during nighttime heat storage is dropped directly into the heat storage tank 2 through the pressure holding and flow rate adjusting valve 13, and the water level in the heat storage tank 2 rises due to the cold water and overflows the weir portion 12. The cold water is pumped up by the pump 14 and returned to the return pipe 8, and the heat storage tank 2
I try to stabilize the water level inside. Therefore, unlike the conventional case of FIG. 2, a heat exchanger as in the conventional case is not required, and therefore, in the central heat source device 6, for example, it is sufficient to produce cold water of about 7 ° C. Can be improved and the space can be reduced. In addition, it is possible to constantly stabilize the amount of water in each heat storage tank and prevent drought and overflow accidents.
