持っている。FIG. 5 shows an example of a floor heating system using a latent heat storage material that has been put into practical use.
This device heats a heater by using midnight power to store heat in a heat storage body, and repeats a cycle of heat storage at night and heat release at daytime. The structure is such that a heat storage body 2 is provided below the floor finishing material 1, and a heater 3, a heat storage body 4, and a heat insulating material 5 for preventing heat radiation to the underfloor are provided below the heat storage body 2. In this structure, since both sides of the heater 3 are in contact with the heat storage bodies 2 and 4, the heat storage efficiency is better than that in the case where only one side of the heater 3 is in contact with the heat storage body 2 (there is no heat storage body 4). It has the feature that it can store heat uniformly in the entire heat storage bodies 2, 4.

割合が少ないという問題点があった。The heat stored in the upper heat storage material 2 radiates heat relatively quickly, while the heat stored in the lower heat storage material 4 becomes difficult to radiate because the heater 3 becomes a thermal resistance. .. Therefore, there is a problem that the next heat is stored while the heat is not radiated so much, and the ratio of the amount of heat radiated into the room to the input power is small.
