るようにするのである。(Background technology) A surface heating device that uses radiant heat forms a comfortable heating system because it evenly heats the room and pleasantly stimulates the hot points of the human body. For this purpose, heat storage building materials with a heat storage structure are being used.In other words, heat generated using cheap late-night electricity, solar heat, or waste heat from other heat sources is stored in heat storage materials. The heat is then used for heating.

などが知られている。Until now, concrete and water have been used as heat storage materials. However, recently, latent heat storage materials have been used which have a larger amount of heat storage per volume than these heat storage materials and which store and release heat at a constant temperature. Such a heat storage material utilizes latent heat accompanying a phase change of a substance for heat storage and radiation. For example, hydrated salts such as calcium chloride and sodium sulfate are known as such substances.

側最表面には、仕上材１６が貼着されている。By the way, in such materials, when the thickness of the heat storage material is increased in an attempt to increase the amount of heat stored, these materials generally have a disadvantage in that their heat storage and release properties deteriorate due to their low thermal conductivity. . Therefore, as we will see in Part 2, a heat storage building material 11 was devised in which the latent heat storage material 13 is made into mini-capsules, the surface area of which is increased, and a large number of these capsules 13 are mixed into the base material 12. This heat storage building material 11 includes a heating element 14 for supplying stored heat on the indoor side of a base material 12, and the other side of the heating element 14 is covered with a heat insulating material 15. There is. heating element 1
4, various things are considered, such as an electric heater, a hot water pipe, and a hot air duct. A finishing material 16 is attached to the outermost surface of the heat storage building material on the indoor side.
このような蓄熱建材１１には、さらに、つぎのような問

２の厚みが厚くなるほど放熱面温度を一定に保つことが
できなくなるという問題である。すなわち、建材１１に
は、厚み方向に温度勾配が生じるため、室温が低下した
とき、基材１２のうち、全体で放熱が起きるのではなく
、温度の低い室内側に近い部分から順次放熱が行われ、
基材１２の内部では部分的にのみ放熱が行われるように
なる。そして、室内側に近い部分の放熱が終わり室温が
さらに低下して始めて、より内部の蓄熱材が放熱するよ
うになるので、放熱面温度は実質的に低下傾向にあり、
結局、放熱面温度を一定に維持することができないこと
となるのである。Such a heat storage building material 11 also has the following problems. That is, the encapsulated latent heat storage material 13
are made of materials having the same transformation point, so the base material 1
The problem is that as the thickness of 2 increases, it becomes impossible to keep the temperature of the heat dissipation surface constant. In other words, since a temperature gradient occurs in the thickness direction of the building material 11, when the room temperature decreases, heat is not radiated from the entire base material 12, but from parts of the base material 12 that are closer to the indoor side where the temperature is lower. I,
Heat is dissipated only partially inside the base material 12. Then, only after the heat dissipation in the area near the indoor side has finished and the room temperature has further decreased, will the heat storage material inside begin to dissipate more heat, so the heat dissipation surface temperature will actually tend to decrease.
As a result, the temperature of the heat dissipation surface cannot be maintained constant.
以上の点に鑑み、この発明は、放熱時に放熱面温度をほ
ぼ一定に保つことができる蓄熱建材を提供することを目
的とする。In view of the above points, an object of the present invention is to provide a heat storage building material that can keep the temperature of the heat radiation surface substantially constant during heat radiation.

とを特徴とする蓄熱建材を要旨とする。To achieve the above object, the present invention provides a heat storage building material in which latent heat storage materials having different phase transition temperatures are dispersed in a base material, wherein the latent heat storage materials have a low phase transition temperature on the indoor side.
The main feature is a heat storage building material that is characterized by being dispersed so that the phase transition temperature is high on the outdoor side.
以下にこれを、その一実施例をあられす図面を参照しつ
つ詳しく説明する。This will be explained in detail below with reference to the accompanying drawings, one embodiment of which will be described below.

度をほぼ一定に維持することができることとなる。FIG. 1 schematically shows the cross-sectional structure of the heat storage building material according to the present invention. This heat storage building material 1 is used as a flooring material, and has a finishing material 6 adhered to its indoor surface, and a base material 2 containing an encapsulated latent heat storage material is disposed therein. It has a structure in which a heating element 4 and a heat insulating material 5 are laminated on the lower surface which is the outdoor side (under the floor side). In the base material 2, latent heat storage materials 3a having a low phase transition temperature are dispersed on the indoor side, and latent heat storage materials 3b having a high phase transition temperature are dispersed on the outdoor side. This is convenient because when the room temperature drops and the heat storage material starts dissipating heat, the temperature distribution inside the base material and the distribution of the phase transition temperature of the heat storage material almost match. Heat dissipation by the heat storage material is carried out evenly throughout the thickness of the base material, that is, in the thickness direction of the base material, so only the heat storage material near the indoor side radiates heat, and the heat storage material inside remains in a heat storage state. Inefficient situations such as this can be avoided. Therefore, when the heat storage building material according to the present invention radiates heat, the temperature of the heat radiating surface can be maintained substantially constant until it loses its latent heat.

るようになる。On the other hand, even during heat storage, since the heat storage material 3b with a high phase transition temperature is placed near the heating element 4, heat storage in the heat storage material dispersed in the base material is carried out smoothly and effectively. It will be carried out accordingly. Therefore, in the heat storage building material according to the present invention, even when a thick base material is used, the heat storage and radiation can be carried out smoothly.

なる。The figure shows an example of a heat storage building material in which the latent heat storage material dispersed in the base material has two types of phase transition temperatures: high and low.
It is more preferable to configure the heat storage building material to have a multilayer structure by sequentially arranging various types of heat storage materials with smaller differences in phase transition temperature between the heat storage materials in the thickness direction of the base material.

などであってもよい。Various organic and inorganic latent heat storage materials are conceivable, but are not particularly limited, and heat storage materials having different phase transition temperatures may be selected as appropriate. The base material is also not particularly limited, but -C
Specifically, gypsum, cement, etc., which easily disperse the encapsulated latent heat storage material, are preferable. The heating element may be an electric heater that uses inexpensive late-night electricity, or may be a hot water pipe, hot water duct, etc. that uses solar heat or waste heat.

行うことができるので、都合がよい。Since the heat storage building material according to the present invention has the above-mentioned configuration, it is possible to maintain the temperature of the heat dissipation surface almost constant during heat dissipation, thereby realizing comfortable heating. Even when the thickness is large, heat can be effectively dissipated, which is convenient.
