The heat exchanger 23 of No. 1 is pipe-connected to the use side heat exchanger 25, and the heat of the refrigerator unit 21 is used as, for example, an air conditioning heat source via the heat exchanger 23 and the use side heat exchanger 25. There is. Further, the bypass pipe 27 is branched to the use side heat exchanger 25, and the brine of the cold heat source system, which has been heat-exchanged in the heat exchanger 23, returns to the heat exchanger 23 without passing through the use side heat exchanger 25. It can be refluxed. Then, a heat storage / radiation heat exchanger 29 is provided between the bypass pipe 27 and the heat exchanger 23, and the brine passing through the bypass pipe 27 is transferred to the heat storage tank 31 side via the heat storage / radiation heat exchanger 29. It is designed to exchange heat with brine. In the closed heat storage system configured in this way,
Open / close valve 3 of bypass pipe 27 during cooling operation at light load
3, the brine (cold water) is supplied from the heat exchanger 23 to the utilization side heat exchanger 25 by driving the refrigerator unit 21, and is used as a heat absorption source for indoor cooling. Further, during summer cooling, the brine on the side of the heat storage tank 31 is circulated by the heat storage tank pump 35, and heat is exchanged between the brine after passing through the heat exchanger 25 on the use side and the heat exchanger 29 for heat storage and radiation, and the high temperature after absorbing heat.

転が望めなかった。However, in the conventional closed pipe type heat storage system, since the temperature difference between the cold heat source system brine and the heat storage source system brine is large, the heat storage operation and the cooling / heating operation are alternately performed. During the heat storage operation, the brine of the cold heat source system is passed only through the heat storage / radiation heat exchanger 29 and cannot be passed through the use side heat exchanger 25, and the night heat storage time zone (22:00 to 8:00) The air conditioning operation could not be performed. Further, in the conventional closed pipe type heat storage system, one heat storage / radiation heat exchanger 29 is shared between the heat storage operation and the heat radiation operation, while there is a difference in the required heat exchange amount between the heat storage operation and the heat radiation operation. Therefore, it is impossible to select a heat exchanger and an attached device (circulation pump, etc.) that are suitable for the heat storage operation and the heat radiation operation, respectively, so that the efficient heat storage and heat radiation operation cannot be expected.

熱システム。1. In a closed pipe type heat storage system in which a cold heat source system brine and a heat storage source system brine are circulated in separate and independent systems, a supply pipe is provided between the outlet side of the cold heat source and the inlet side of the air conditioner. An open / close valve for controlling the brine supply to the air conditioner is provided on the inlet side or the outlet side of the air conditioner, and the return pipe connected to the outlet side of the air conditioner is branched into two, An on-off valve is provided on one side and one of the return pipes is connected to a return header that communicates with the inlet side of the cold heat source by piping, and an on-off valve is provided on the other side of the return pipe and the other side of the return pipe is connected to a heat radiating heat exchanger. The bypass pipe for bypassing the air conditioner is branched from the supply pipe, an opening / closing valve is provided in the bypass pipe, and the bypass pipe is passed through the heat storage heat exchanger. Distributed to Both ends are connected to a high temperature part and a low temperature part of the heat storage tank, and both ends are respectively connected to the high temperature part and the low temperature part of the heat storage tank by piping through the heat storage heat exchanger. A heat storage system of a sealed pipe type, characterized in that pipes for heat radiation to be connected are piped through the heat exchanger for heat radiation.
