実用化されている。In recent years, thermal storage cooling/heating has been developed, in which heat generated using cheap energy such as late-night electricity or waste heat from other heat sources is stored in a heat storage surface material using latent heat storage material and used as a cooling/heating source. has been put into practical use.

するのである。When this heat storage surface material 12 is used for heating, a material having a phase transition point corresponding to the desired indoor temperature in winter is used as a latent heat storage material 11a. For example, if the desired room temperature in winter is 20°C, the phase transition point is 2
The floor of this room will be made of N-thermal surface material using a latent heat storage material with a temperature of 0°C. In winter, when the room temperature in this room reaches 20℃ or higher, the phase transition point of the latent heat storage material, due to heating or daytime sunlight,
The latent heat storage material undergoes a phase change and absorbs latent heat. Conversely, when the room temperature in the same room is below 20℃, such as when heating is not performed or at night,
The latent heat storage material undergoes a reverse phase change and releases the latent heat it absorbed earlier, warming the same room. As a result, this N-thermal panel 12 functions to maintain the room temperature of the same room at 20° C. during the winter.

持するような働きをするのである。Such a heat storage surface material 12 can also be used for air conditioning in the summer depending on the latent heat storage material used. For example, if the floor of a room is made of a heat storage surface material 12 using a latent heat storage material with a phase transition point of 28°C, when the room temperature in this room is below 28°C during summer cooling or at night, the latent heat The heat storage material undergoes a phase change and releases its latent heat. Conversely, when the room temperature exceeds 28°C during non-air conditioning or during the day, the latent heat storage material undergoes a reverse phase change, absorbs latent heat, and cools the room. As a result, the heat storage surface material 12 functions to maintain the room temperature of the same room at 28° C. in summer.

からである。By the way, since the production cost of such a heat storage surface material is significantly higher than that of ordinary building materials, a material with high added value that can be used for both cooling and heating is desired. However, the conventional heat storage surface material is used only in either the summer cooling demand period or the winter heating demand season, and in order to be used for both cooling and heating, at least two types of heat storage surface materials are required. A latent heat storage material was required. This is because, for example, if one type of latent heat storage material with a phase transition point of 24°C, which is between the two examples above, is used, the room temperature will rarely fall below 24°C during the summer cooling demand period. Furthermore, it is rare for the room temperature to exceed 24°C during the winter heating demand period. Therefore, the latent heat material cannot exchange enough heat to be used for cooling and heating, so the cooling and heating effects that utilize the absorption and release of the latent heat are actually of little use. .
この発明は、上記事情に鑑みてなされたものであって、
１種類の潜熱蓄熱材を用いて夏は冷房に、冬は暖房に利
用できる蓄熱面材を提供することを目的とする。This invention was made in view of the above circumstances, and

とする。In order to achieve the above object, the present invention provides a heat storage surface material comprising a heat storage layer using a latent heat storage material and having a planar structure as a whole, in which the latent heat storage material undergoes a phase transition in a desired room temperature range. The gist of the present invention is a heat storage surface material characterized in that the heat storage surface material has a dot and a heat insulating material layer is stacked on the heat storage layer via a heater.

This heat storage surface material 2 has a planar heat storage layer 1 in which heat storage bodies in which a latent heat storage material 1a is sealed in a container 1b are connected.
A heat insulating material layer 4 made of a heat insulating material is stacked so as to sandwich the heater 3 provided on one surface of the heat storage layer 1. The latent heat storage material 1a has a phase transition point of 25 to 28
It was selected from those in the temperature range of ℃.

範囲にある必要がある。In this configuration, when the room temperature of the room where the heat storage surface material 2 forms the floor or the like falls below the phase transition point of the latent heat storage material 1a during air conditioning in summer or at night, the latent heat storage material 1a undergoes a phase change and its Releases latent heat. Conversely, when the room temperature in the same room exceeds the phase transition point during non-air conditioning or during the day, the latent heat storage material 1a undergoes a reverse phase change, absorbs WI heat, and cools the room. As a result, this heat storage surface material 2 tries to maintain the room temperature of the same room at the phase transition point in the summer, but in order for the latent heat storage material 1a to work as described above, its phase transition point is The temperature must be in the range between the highest and lowest room temperatures in the room during summer.

いては、その選択に特別の注意を要する。というのは、
無機水和塩系物質には過冷却現象を起こすものがあり、
これらの物質の実際の凝固温度はその融点よりも２〜３
℃程度低い場合が多いからである。By the way, the room is rarely heated to a high room temperature of 25 to 28 degrees Celsius in winter, so there is very little opportunity for the latent heat storage material 1a to absorb a large amount of heat and store it in the form of latent heat. Therefore, in the winter, the heater 3 generates heat using intermittent but inexpensive late-night electricity, and this heat is stored in the latent heat storage material 1a in the form of latent heat. During times when there is no power supply, this stored heat is released and used for radiant heating, making it possible to provide heating with low operating costs. Sumitermal 28
(manufactured by Sumitomo Chemical@), oil-based products under the product name Thermotop (
As for the paraffin type, those having a phase transition point in the temperature range of 25 to 28°C, such as octadecane, are preferable. Among these latent heat storage materials, special care must be taken in selecting inorganic hydrated salt-based materials. I mean,
Some inorganic hydrated salt substances cause supercooling phenomenon.
The actual solidification temperature of these substances is 2-3 times higher than their melting point.
This is because the temperature is often as low as ℃.
このことは、部屋の室温と相転移点とのわずかな温度差

ある。一方、油脂系またはパラフィン系の潜熱蓄熱材は
このような凝固点と融点の差がほとんどないので、この
発明に使用する潜熱蓄熱材として好ましいものである。This should be given sufficient consideration in order to store and release heat by utilizing the slight temperature difference between the room temperature and the phase transition point. On the other hand, oil-based or paraffin-based latent heat storage materials have almost no difference between their freezing point and melting point, and are therefore preferable as the latent heat storage material used in the present invention.

のである。FIG. 2 shows a second embodiment of the heat storage surface material according to the present invention. In this heat storage surface material 6, the latent heat storage material 5a is
A planar heat storage layer 5 is constituted by a series of heat storage bodies encapsulated in the heat storage body. A heater 7 is placed on one surface of this heat storage layer 5.
is provided, and a hollow part 9 is provided in between so as to sandwich the heater 7 therebetween.
A heat insulating material layer 8 made of a heat insulating material is stacked on top of the other. The latent heat storage material 5a is selected from materials whose phase transition point is in the temperature range of 25 to 28° C., as in the first embodiment.

At this time, the air in the hollow portion 9 is also cooled or warmed by the latent heat storage material 5a, similar to the air in the room whose floor etc. are configured with the heat storage surface material 6.

Also,
Even in winter, efficient heating can be achieved by converting the stored heat into warm air and sending it into the room.

Good. Furthermore, when used as a wall material, this heat storage surface material has a large thickness structure of a heat storage body and a heater insulation material, so it is necessary to pay attention to livability. When used as a ceiling material, the thickness of the heat storage surface material is thought to pose little problem in terms of design. However, consideration must be given to the finishing material of the surfaces visible from inside the room.
