BACKGROUND ART In recent years, buildings such as buildings are often installed with heat storage tanks using water as a heat medium, which can reduce operating costs and utilize inexpensive electricity mainly at night.
In such a heat storage tank, a foot valve is installed at the end of the piping that pumps up the water in the tank and the end of the piping that discharges water into the tank, and the piping is left disconnected at the discharge part. . For this reason, the flow rate at the discharge part is high, and cold water or hot water having different temperatures mix in the heat storage tank, which significantly deteriorates the thermal efficiency of the heat storage tank. In addition, when cold water or hot water produced by primary-side heat source equipment such as a refrigerator or boiler is stored in a heat storage tank and then supplied to secondary-side equipment such as an air conditioner or fan coil unit, the above-mentioned mixing allows the cold water to be The temperature of the hot water increases, the temperature of the hot water decreases, and the high-quality cold (hot) water produced by the primary equipment cannot be used effectively.

This heat storage tank is a heat storage tank that stores hot water for heating or cold water for cooling. The high-temperature chamber has a float that moves up and down to follow the tank water level, and the opening at its upper end opens directly below the water surface, and the low-temperature chamber has an opening at its lower end. The opening is close to the bottom of the tank.

熱の利用効率を高めることができる。 The high-temperature cold water returned from the secondary equipment during cooling is discharged into the high-temperature chamber of the heat storage tank. Also, the high temperature cold water in the high temperature chamber is pumped up to the primary heat source equipment. During heating, hot water heated by the primary heat source equipment is discharged into the high-temperature chamber. Also, the high-temperature hot water in the high-temperature chamber is pumped to the secondary side equipment. During cooling, low-temperature cold water cooled by the primary heat source equipment is released into the low-temperature chamber. Also, the low-temperature cold water in the low-temperature chamber is pumped up to the secondary equipment. During heating, low-temperature hot water cooled by the secondary equipment is released into the low-temperature chamber. Furthermore, the low-temperature hot water in the low-temperature chamber is pumped up to the primary heat source equipment. From the above, the amount of water released from both the high-temperature chamber and the low-temperature chamber minus the amount of water pumped out flows into or flows into the heat storage tank through the openings. The flow velocity at this opening is kept low, so the temperature inside the heat storage tank is different from cold (warm).
Mixing of water can be minimized. Therefore, the heat storage efficiency and the heat utilization efficiency on the primary side and the secondary side can be improved.

通り、槽内に流出入する。 During cooling, this high-temperature side pumping and discharging section discharges the heated cold water (for example, about 15 degrees) returned from the secondary side equipment into the chamber 1 from the discharge pipe 2. On the other hand, the high-temperature cold water in the chamber 1 is sent via the pumping pipe 3 to the refrigerator, which is a secondary device. During heating, hot water heated by the primary heat source device is discharged from the discharge pipe 2 into the chamber 1. On the other hand, hot water with a high temperature inside the chamber 1 is sent to the secondary side equipment via the pumping pipe 4.

Alternatively, it is sent at a low flow rate to the top of low-temperature water (during heating) to suppress mixing of water in the tank. Furthermore, when cold water (during cooling) or hot water (during heating) with a high temperature at the surface layer of the tank flows into the chamber 1 from the opening 7, mixing of the water in the tank is similarly suppressed.
Note that the discharge pipe 2 opens above the foot valve 13 at the lower end of the pumping pipe 3 and the pumping pipe 4, and the air mixed with the return water discharged from the discharge pipe 2 is taken to the pumping pipe 3 and the pumping pipe 4. is prevented from occurring.
