本発明は、無機水化物を含有する蓄熱材を収納

熱を放熱するという特徴を有する。特に無機水化
物の融解潜熱を利用した蓄熱材は、単位体積当り
の蓄熱量の大きなことが知られている。 In general, there are two types of heat storage materials: those that utilize the sensible heat of substances and those that utilize latent heat. Heat storage materials that use latent heat have a larger amount of heat storage per unit weight and unit volume than heat storage materials that use sensible heat, and require only a small amount of heat storage material to store the required amount of heat. Therefore, the heat storage device can be downsized. A heat storage material that uses latent heat has the characteristic that, unlike a heat storage material that uses sensible heat, the temperature does not drop as heat is released, and instead radiates heat at a constant temperature at a transition point. In particular, heat storage materials that utilize the latent heat of fusion of inorganic hydrates are known to have a large amount of heat storage per unit volume.
ところが、無機水化物およびこれらの混合物

密閉構造として、水分の出入を避けなければなら
なかつた。 However, inorganic hydrates and mixtures thereof have efflorescence properties in which water in them evaporates or deliquescent properties in which they absorb water, and the amount of water evaporation increases as the temperature rises. For this reason, the heat storage tank had to have a sealed structure to prevent moisture from entering and exiting.
しかし、蓄熱槽を密閉構造とすれば、蓄熱材の

保安上の問題点もあつた。 However, if the heat storage tank has a sealed structure, there are practical drawbacks in that it not only causes inconvenience in storing the heat storage material, but also leads to an increase in production costs. Additionally, if the structure is completely sealed, there is a risk of explosion due to expansion of internal gas due to temperature.
There were also security issues.

フツ化エチレン樹脂が知られている。 The present invention provides an inexpensive and highly safe heat storage tank in which the heat storage material does not deteriorate due to evaporation or absorption of moisture. A feature of this heat storage tank is that at least a portion thereof is provided with a semipermeable portion made of a material that has good gas permeability and does not easily allow moisture to pass through. Polyfluorinated ethylene resin is known as a material having such semipermeability.

一つである。 Polyfluoroethylene resin has a very low water absorption rate of 0.00% and a moisture permeability rate of 0.06 g/m 2 ·day, and has the characteristics of allowing air to pass through easily, making it one of the most suitable materials.
以下、本発明の蓄熱槽について詳細に説明す
る。 Hereinafter, the heat storage tank of the present invention will be explained in detail.

なく、蓄熱材はきわめて安定に機能する。 The principle of this heat storage tank will be explained by taking as an example a case where a warming heat storage material is used as an inorganic hydrate-based heat storage material. First, during heat storage, the heat storage material 3 is heated and melted. At the time of this melting, the volume of the heat storage material 3 increases as it melts, and the water vapor pressure also increases as the heat storage material becomes liquid. Furthermore, the air in the heat storage tank is naturally heated and expands. Therefore, if at least a portion of the heat storage tank is not provided with a semi-permeable part as described above, the inside of the heat storage tank will be under high pressure, and if it is heated abnormally, there is a risk of explosion. There is also gender. However, in this embodiment, as shown in the figure, since the semi-permeable part 1 is provided in a part of the heat storage tank, the inside and outside of the heat storage tank are connected with respect to air, so the inside of the heat storage tank is The pressure in the heat storage tank is the same as the surrounding pressure, so there is no abnormally high pressure inside the heat storage tank, and the load on the heat storage tank is significantly reduced compared to a closed type heat storage tank. Furthermore, in the heat storage tank of the present invention, the water vapor inside is sealed, and even if heat storage and heat radiation are repeated, the amount of moisture in the heat storage tank is kept constant. There is no deterioration, and the heat storage material functions extremely stably.

用することができる。 The above-mentioned polyfluorinated ethylene resin is suitable as a material that allows air to pass through easily but does not allow water vapor to pass through, but any material that has the function of allowing air to pass through easily but preventing water vapor from passing through may be used. can do.

もよいのは勿論である。 In addition, in the above embodiment, air can easily pass through, but
We have shown the case where one semi-permeable part, which is difficult for moisture to pass through, is provided at the top of the heat storage tank, but as long as the size, number, shape, and position of this part match the purpose of preventing moisture evaporation and absorption. Needless to say, it can be optional. Furthermore, in actual use, the heat storage tank wall has a structure in which a heat insulating material or the like is interposed between the inner wall and the outer wall. Therefore, it goes without saying that the semi-permeable portion may be provided on either the inner wall or the outer wall.

いものである。 As described above, the heat storage tank of the present invention has a relatively simple structure and has a relatively simple structure that prevents water evaporation. Deterioration of the heat storage material due to inhalation is prevented, and as a result, it is inexpensive and highly safe.
