じても冷液層と温液層皓混合しないように作用゛する。The specific weight of the float is adjusted so that the specific weight of the liquid is at the optimal temperature layer that differentiates between the cold liquid layer with a large specific weight of the target heating medium liquid and the hot liquid layer with a small specific weight. According to the specific gravity of the cold liquid layer and the hot liquid layer, the liquid moves up and down on the interface between the two and floats, and the pulsation of water in the tank due to the inflow and discharge of the liquid causes the engraving of the living statement (in the contents). No change) hN' It acts to prevent the cold liquid layer and hot liquid layer from mixing.

が増加するので浮子11は槽内を上昇する。In FIG. 7, a water supply pipe 12 is connected to the lower end of a heat storage tank 10 for hot water supply.
A hot water supply pipe 13 is provided at the upper end, and connecting pipes 15, 16 and 1 are connected between the inlet side of the solar heat collector 140 and the center and lower end of the heat storage tank 10, and between the outlet side and the upper end, respectively.
7, and a float 11 whose specific gravity has been adjusted to a predetermined specific weight is inserted into the heat storage tank 10. In FIG. 7, hot water 20 collected by the heat collector 14 is stored in the upper half of the heat storage tank 10, the lower half is filled with cold water 21, and the float 11 is stored in the heat storage tank 10.
It is located at a height near the center of the Then heat collector 1
As the heat storage progresses further in step 4, the water supplied from the connecting pipe 16 is heated and accumulates in the upper part of the heat storage tank 10, and the float 11 descends in the tank as shown in FIG. Next, as shown in FIG. 9, when hot water is supplied to the outside through the hot water supply pipe 13, cold water is supplied from the water supply pipe 12 to the water reducing valve, so the amount of cold water with a large specific weight increases in the lower part of the heat storage tank 10. Therefore, the float 11 rises in the tank.

1. The tank is always shielded by a floating float 11 that moves up and down according to the specific gravity, and even if water pulsates in the tank during hot water supply or water supply, hot and cold water mixes and the temperature is neutralized. The hot water 920 at the top is not cooled down, allowing efficient use of hot water.
