Conventionally, there is an "overflow weir" type heat storage tank that is said to have an excellent temperature stratification effect and good thermal efficiency. As shown in Fig. 4, this type of tank consists of a large number of tanks 2 separated by partition walls 1, and two adjacent tanks 2a and 2b have an overflow weir 3 that opens at the upper part of one tank 2a, and an overflow weir 3 that opens into the upper part of one tank 2a. Slip weirs 4 that open to the lower part of the water layer 2b are provided on both sides of the partition wall 1, and a through passage 5 is bored in the partition wall 1 between them.
It is configured by connecting two water tanks 2a and 2b.

らないことが知られている。 However, in order to promote the formation of thermal stratification in the heat storage tank, it is necessary to increase the outflow velocity and inflow velocity v (m/sec) of the water in the water tank 2 at the edge of the submerged weir and overflow weir.
is known to have to be designed to satisfy, for example, the following:

difference in density of water. (Kg/m 3 ) ρ 0 : Density of water that is storing cold (heat). (Kg/m 3 ) However, in actual use, the water level in the tank constantly fluctuates due to turning on and off of the circulation pump, or controlling the flow rate of the circulating amount of cold storage (heat) water in response to fluctuations in the heating and cooling load. Therefore, in the above equation, when the value of d becomes small and the flow velocity v becomes large, the inequality no longer holds true, heat diffusion due to water mixing increases, the exergy of cold storage (hot) water decreases, and heat storage There was a drawback that efficiency decreased.

まれる。 The flow of cold water when the heat storage tank of this embodiment is in a cold storage state will be explained below with reference to FIGS. 1 and 3.
Initially, the water tank 2a was filled with lukewarm water after being used for cooling, but the cold water supplied from the refrigerator through the pipe 16 in FIG.
The water is sent to the bottom of the tank and gradually replaced by lukewarm water. The open end ring 1 of the pipe line 6 in Fig. 1 where the interface between cold water and lukewarm water gradually rises and floats on the upper layer of the tank.
When the 0 position is reached, the cold water flows through the pipe 6 into the lower part of the water tank 2b. Aquarium 2b or aquarium 2
As in step a, lukewarm water is replaced with cold water. This exchange of lukewarm water and cold water occurs between the upper and lower water tanks and between the water tanks, and the upper layer of the water tank 2h at the final end has the highest temperature water. This water is sent to the refrigerator via a flexible conduit 17 that opens in the upper layer of the tank.

め設定した一定値を越えることはない。 At this time, the distance d from the water surface of the open ends of the pipes 17 and 6 that open to the upper part of the water tank 2h and the water tank 2a is always constant regardless of the height of the water level. Therefore, the flow velocity v of the outflowing water does not exceed a preset constant value. Even at the inflow opening end of the water tank 2b, since the distance from the opening end to the tank bottom is always constant, the flow of water flowing in will never exceed a preset constant value.

The open end of 8 is moored to the bottom of the tank with a cable 13, and is also connected to a float 14 floating in the water by a tow cable 15 and pulled upward. However, the method is not limited to this method. For example, a support rod may be provided protruding from the bottom of the tank, and the pipes 16 and 8 may be fixed to the support rod so that the open ends thereof are kept at a predetermined distance from the bottom of the tank. In short, the pipes 16 and 8 may be fixed so that the open ends maintain a predetermined depth from the tank bottom.
