暖房用の蓄熱装置に使用するのは得策ではない。
As a heat storage device that stores thermal energy (including so-called cold storage; the same applies hereinafter) by introducing warm or cold air, granular thermal storage materials that utilize sensible heat, such as those made by depositing gravel, have been known. There is. However, the apparent heat capacity of gravel is about 350kcal/m 2 ℃, which is about one third of that of water.
Accordingly, a large heat storage capacity is required, and the heat dissipation rate is fast. Therefore, it is not a good idea to use this as a heat storage device for long-term heating.

その構成上採用が困難である。 In addition, conventional heat storage devices in which latent heat storage materials such as magnesium nitrate/hexahydrate sealed in aluminum capsules are deposited have a low-temperature area below the melting point on the outflow side of the heat medium during the heat dissipation period. This has the disadvantage of significantly reducing the thermal response speed, but by providing a packed layer of sensible heat utilization granular heat storage material such as alumina balls on the above-mentioned outflow side of the heat medium,
Attempting to speed up the thermal response speed (Japanese Patent Application Laid-open No. 1983
-10696 Publication) is known, but it is impossible to use this as an underfloor heat storage device for floor heating.
Due to its structure, it is difficult to adopt it.

As is clear from the above description, the device of the present invention includes a sensible heat utilization granular heat storage material body having an inlet side header and an outlet side header formed on both sides, and a member constituting a floor or substantially a floor (in the embodiments). Since a heat storage material body using latent heat is interposed between the upper wall 1a) of the housing 1, the warm air sent to the inlet side header through the air supply duct is transferred to the granular heat storage material body using sensible heat, and the heat storage material body on the opposite side. The heat is sent into the room through the outlet header and the air supply duct, and is stored in the sensible heat utilization granular heat storage material body. As a result, the latent heat-utilizing heat storage material body also stores heat while causing a phase transition effect, and then slowly causes a reverse transition and performs floor heating isothermally over a long period of time by dissipating the latent heat. On the other hand, when the latent heat storage material body reaches its freezing point, its thermal conductivity rapidly decreases and it functions as a type of heat insulating material, which helps maintain the heating effect.

する。 In addition, the cold air sent to the inlet side header through the air supply duct is also
The coolant is sent into the room through the outlet header and air duct on the opposite side, and is stored in the sensible heat utilization granular heat storage material body. Thereby, the latent heat utilizing heat storage material body maintains a solid phase and functions as a heat insulating material that protects the sensible heat utilizing granular heat storage material body, and prevents dew condensation on the floor surface.
本発明はさらに次の効果を奏する。 The present invention also has the following effects.
潜熱利用蓄熱材体は、概して平面積が広くし

容積を縮小して全体をコンパクトにできる。 Latent heat storage materials generally have a large surface area and can sufficiently store heat even if they are thin, which is also advantageous for heat dissipation. As a result, the heat transfer area per unit area can be increased, and the volume of the sensible heat utilization granular heat storage material body can be reduced to make the whole body compact.
潜熱利用蓄熱材体の潜熱の放散による暖房熱
の供給を等温的に長時間にわたつて行うことが
できるため、その省エネルギー効果も大であ
る。 Since heating heat can be supplied isothermally over a long period of time by dissipating the latent heat of the latent heat storage material body, the energy saving effect is also large.

蓄熱材は本装置の蓄熱容量を増大するよう機能
する。 Sudden temperature changes within the equipment are absorbed within the capacity of the latent heat of solution possessed by the latent heat storage material to maintain a stable bed temperature, and the latent heat storage material increases the heat storage capacity of this equipment. It works like that.
顕熱利用粒状蓄熱材体の両側にヘツダーを設
