Description of the Related Art In a conventional heat storage type floor heating system, as shown in FIG. 2, a heat storage material 15 laid on a floor surface 14 is heated by a heater 16 or the like using late-night power to store heat, which is stored in the daytime. The amount of heat was released naturally. Further, as shown in FIG. 3, in the hot water circulation type floor heating system, floor heating is performed by circulating hot water that has been stored by the midnight power to the heating panel 11 by the daytime transport pump 13.

Further, in the emulsion or suspension state, since the viscosity is high and stirring is unlikely to occur, it becomes easy to form a temperature stratification in the heat storage tank. This means that only emulsions or suspensions can be used if desired.

熱槽１内の蓄熱材４の潜熱を有効利用する事ができるEXAMPLE First, a heat storage type floor heating system of the present invention is shown in FIG.
It will be explained based on. First, in the heat storage mode, the heat storage material 4 stores heat by receiving heat from the heat exchanger 2. When stirring is required, the use of the stirrer 3 eliminates the temperature stratification in the heat storage tank 1 and improves the heat exchange performance. Next, the heat radiation operation will be described. The stored heat storage material 4 is in an emulsion state and is taken out from the upper portion of the heat storage tank 1 by operating the transfer pump 5 and opening the flow rate adjusting valve 6 and transferred to the floor heating panel 8 through the pipe 7. By adjusting the transfer amount by the flow rate adjusting valve 6, the floor heating panel 8 can use only the latent heat of the heat storage material 4 to keep the temperature of the floor heating panel 8 constant. Then, the heat storage material 4 (in the suspended state here) that has passed through the floor heating panel 8 is returned to the lower portion of the heat storage tank 1. In this case, since the heat storage material 4 has a high viscosity, stirring is less likely to occur, and in the heat storage tank 1, temperature stratification such as suspension at the bottom and emulsion at the top occurs. By repeating this circulation, the latent heat of the heat storage material 4 in the heat storage tank 1 can be effectively used.
