In order to prevent breakage, leakage, etc., it is desired to leave the air layer without filling the entire container with the latent heat storage material. This air layer needs 5 to 20% of the entire volume in the container, and in this case, the latent heat storage material occupies the remaining 80 to 95% of the volume in the container.

  However, as in Patent Document 1, when the container enclosing the latent heat storage material is accommodated in the floor material body, the air layer formed in the upper part of the container becomes the indoor side and heat between the floor material body is generated. Since the movement is hindered, the effect of the latent heat storage material cannot be fully exhibited.

  Therefore, as shown in Patent Document 2, a liquid such as oil is enclosed in the container together with the latent heat storage material, and the liquid layer is communicated to the external container through the communication path, so that the volume of the latent heat storage material is changed. It has been proposed to prevent the formation of an air layer in the upper part of the container by supplying and discharging liquid to and from the external container.

The container 10 assembled | attached to the flooring main body 1 and the back surface cover material 7 are provided, and it is constructed | assembled on a floor base material (not shown) in the indoor floor part.

  The floor material body 1 constitutes a heat transfer object. This floor material body 1 is usually made of, for example, a wood material as in general floor materials, and a plurality of container housing portions 2, 2,... Recessed in a rectangular shape, for example, are formed on the back surface thereof. The container 10 is accommodated in the accommodating portion 2. The back cover member 7 is integrally attached and fixed to the back surface of the floor material body 1, and the back surface of the floor material body 1 is covered with the back cover material 7, and each container housing portion 2 has a container 10. The opening is closed in a state in which is accommodated.

  As shown also in FIG. 3, the said container 10 is a thin plate-shaped thing of the magnitude | size which can be accommodated in the container accommodating part 2 of the flooring main body 1 back surface, for example, consists of heat-transfer materials, such as aluminum, As shown in FIG. 1, a latent heat storage material B is enclosed inside. As the heat transfer material of the container 10, for example, polyethylene, polyolefin, PET, ABS or the like can be used in addition to aluminum, but it is necessary to use a material that does not dissolve or swell with the latent heat storage material B to be filled (latent heat storage). Paraffin as the material B swells olefin and the like). Moreover, what vapor-deposited aluminum to the composite of PET and polyethylene can be used.

The latent heat storage material B performs heat storage and heat dissipation by repeatedly melting and solidifying depending on the temperature, and becomes a solid at a temperature lower than the melting point and becomes a liquid at a temperature higher than the melting point (Note that each embodiment and reference) In the drawing showing the form , it is shown in a liquid state). As the latent heat storage material B, for example, normal paraffin whose main raw material is n-octadecane or n-hexadecane is used. This normal paraffin has a melting point of 23 to 28 ° C., basically becomes a solid at a temperature lower than the melting point, and becomes a liquid at a temperature higher than the melting point. The normal paraffin as the latent heat storage material B is used as it is enclosed in an aluminum container as the container 10 as it is, and changes in phase with solid / liquid according to the temperature change. The specific gravity of normal paraffin is about 0.8.

  As the latent heat storage material B other than normal paraffin, inorganic hydrate salts (calcium chloride hexahydrate, sodium sulfate decahydrate, etc.), fatty acids (palmitic acid, myristic acid, etc.), aromatic hydrocarbon compounds (benzene) , P-xylene, etc.), ester compounds (isopropyl palmitate, butyl stearate, etc.), alcohols (stearyl alcohol, etc.), polyalkylene glycols, and the like can be used.

The heat storage material contact portion 15 can transfer heat to the floor material main body 1 in a certain area or more by the contact portion 4 on the bottom surface of the container housing portion 2, so that the latent heat storage material B and the floor material main body 1 in the container 10 are transferred. (Heat transfer object) is always maintained in a heat transfer state. Thereby, the heat transfer between the latent heat storage material B in the container 10 and the floor material main body 1 is performed reliably and efficiently, and the constant temperature effect of the floor surface or the room temperature can be enhanced.
