Description

[Detailed explanation of the idea] This invention relates to a heating waist wall using solar heat.

Traditionally, hot water systems are commonly known as heating systems that utilize solar heat, but they are installed on the roof, circulate water indoors and outdoors, and emit the heat from the hot water indoors. , auxiliary equipment such as piping, pumps, and radiators are required, and their construction is also troublesome.

The purpose of this invention was to solve the above problems by effectively utilizing the waist wall of the building, where furniture cannot be placed inside due to the presence of windows above, and to prevent wasteful heat collection in the summer. Furthermore, the present invention aims to provide a heating wall using solar heat that can prevent wasteful heat radiation to the outdoors when heat is radiated indoors.

In this specification, "inside" refers to the indoor side, and "outside" refers to the outdoor side.

The heating waist wall body using solar heat according to this invention includes a waist wall body made of a heat storage material, which has a solar heat absorbing film on the outer surface and is provided under the window, and a roll-up type insulation curtain placed outside the waist wall body. It consists of a movable heat insulating plate which is arranged inside the waist wall main body so as to be able to rise and fall freely and which covers at least the lower half of the window from the inside when raised.

Concrete, brick, etc. are commonly used as the heat storage body, but in order to increase the heat storage rate, it is preferable to intersperse a large number of sealed containers containing water or a latent heat storage material in the concrete. As the latent heat storage material, sodium sulfate decahydrate, calcium chloride hexahydrate, sodium phosphate decahydrate, caustic soda 1
Water salt, sodium thiosulfate pentahydrate, paraffin, ethylene glycol, etc. are suitable. The material for the container is preferably a thermoplastic synthetic resin such as polyethylene, since the container is filled with contents and then heat sealed. Suitable shapes for the containers include spherical, potbellied, and cylindrical shapes, and in order to evenly scatter them in the concrete, it is best to make them as small as possible. In order to provide a solar heat absorbing film on the outer surface of the waist wall main body, it is preferable to attach, for example, aluminum foil or thin aluminum plate treated with a solar heat selectively absorbing film to the heat storage body using an adhesive or an adhesive. In particular, a coiled aluminum foil with one side treated with a solar heat selective absorption film and an adhesive coated on the other side and covered with a release paper is prepared, and this is cut into a size that matches the area of the heat storage body. It is best to cut it before use. In some cases, an aluminum vapor-deposited synthetic resin film treated with a solar heat selective absorption film may also be used. Incidentally, the solar heat selective absorption film is generally smooth, but in order to increase the surface area, it may have a finely wavy longitudinal section. The solar heat selective absorption film preferably has a solar heat absorption rate α of 0.85 or more and an emissivity ε of 0.3 or less. It is better to paint the inner surface of the heat storage body white or black, or to attach a metal plate such as an aluminum plate with an embossed pattern to the inner surface. The roll-up type insulation curtain is
When this is pulled down, it covers the outer surface of the waist wall main body. Further, it is preferable that the heat insulating curtain is automatically wound up by a spring or the like. In this case, when the heat insulating curtain is pulled down, it is fixed with fixing metal fittings. The movable heat insulating board is made of synthetic resin such as urethane or styrene, or glass wool. The movable insulation board is
Although it is preferable that this is pulled up to the inside of the window, it is not limited to this, and in short, any structure that can be moved so that the waist wall main body can be exposed indoors may be used. In order to form the waist wall body into a unit, it is preferable that the waist wall body and the movable heat insulating board are housed in a frame-like frame made of wood or metal that has been subjected to heat insulation treatment. In addition, if the existing waist wall is made of concrete, this may be used as the waist wall main body.

This invention will be explained below with reference to the drawings.

The heating waist wall using solar heat based on this idea is the first
As shown in the figure, there is a solar heat absorbing film 1 on the outer surface.
A waist wall main body 2 made of a heat storage material and provided below the window 10, a transparent plate 3 placed on the outside of the waist wall main body 2, and a roll-up type heat insulating curtain 4 placed on the outside of the transparent plate 3. and a movable heat insulating board 5 which is disposed inside the waist wall main body 2 so as to be able to rise and fall freely and cover the entire window 10 from the inside when raised.

The solar heat absorption film 1 is provided by forming a solar heat selective absorption film on the outer surface of an aluminum foil, and pasting this aluminum foil onto the waist wall main body 2 with an adhesive or an adhesive. The waist wall main body 2 is made up of a large number of water-tight spherical containers 2b the size of ping pong balls scattered within a concrete 2a. A white paint film 6 is formed on the inner surface of the waist wall main body 2. As the transparent plate 3, a transparent glass plate is generally used, but transparent synthetic resin such as acrylic resin can also be used. A space of about 10 to 20 mm is provided between the transparent plate 3 and the waist wall main body 2, and an air layer 7 is provided here to improve heat retention efficiency. The waist wall main body 2 and the transparent plate 3 are housed in a frame-shaped wooden frame 8 which is heat-insulated. A winding case 9 of the heat insulating curtain 4 is attached to the upper surface of the upper horizontal member 8a of the wooden frame 8. The heat insulating curtain 4 is automatically wound up into the winding case 9 by the action of a spring. Further, the heat insulating curtain 4 is fixed by a fixing fitting in the lowered position. Further, a stop 12 for pulling up the movable heat insulating board 5 is provided at the lower end of the wall 11 above the window 10. In addition, in the figure, 13 is a ceiling and 14 is a floor.

The waist wall body according to this invention is used for indoor heating in winter as follows. That is, during the day, as shown by the solid line in FIG.
is placed inside the waist wall main body 2 so as to cover it, and blocks the waist wall main body 2 and the indoor room I.
Further, the heat insulating curtain 4 is wound up inside the winding case 9, and the solar heat absorbing film 1 is exposed to the outdoors. Sunlight S from outdoors O passes through the transparent plate 3 and hits the solar heat absorption film 1. As a result, sufficient heat is stored in the waist wall body 2 made of a heat storage body with the help of the solar heat absorbing film 1 which absorbs heat well. Therefore, at night, the movable heat insulating board 5 is moved to the inside of the window 10 and removed from the inside of the waist wall main body 2, as shown by the chain line in the figure, and the heat insulating curtain 4 is pulled down. Then, the heat storage waist wall main body 2 is exposed toward the indoor I, so that the heat H stored therein is radiated to the indoor I, heating the indoor I. Furthermore, since the outside of the transparent plate 3 is covered with the heat insulating curtain 4, it is possible to prevent heat from being radiated from the solar heat absorbing film 1 to the outdoors O. Moreover, since the window 10 is covered with the movable heat insulating board 5 from the inside, heat radiation to the outdoors O through the window 10 can be prevented. Of course, the indoor space I can be heated as described above even during the daytime, if necessary. In the summer, if the heat insulating curtain 4 is pulled down to cover the outside of the waist wall main body 2, heat accumulation in the heat storage body can be prevented. Furthermore, if the window 10 is covered from the inside with the movable heat insulating board 5, sunlight S can be prevented from entering the indoor room I.

FIG. 2 shows a case in which a movable heat insulating board 15 is placed inside the wall 11 on the upper side of the window 10 to cover the inside of the window 10, and the upper and lower movable heat insulating boards 15 and 5 are butted against each other from above and below. This is a modified example in which the entire inside of the window 10 can be covered, and both can be fastened together with a hook (not shown).
The upper movable heat insulating plate 15 is fixed so as not to fall under its own weight in the raised position.
The rest is substantially the same as that in FIG. 1, and these are designated by the same reference numerals as in FIG.

The heating waist wall body using solar heat according to this invention includes a waist wall body 2 made of a heat storage material, which has a solar heat absorbing film 1 on the outer surface and is provided under a window 10, and a winding type waist wall body 2 arranged on the outside of the waist wall body 2. The heat insulating curtain 4 is disposed inside the waist wall main body 2 so as to be able to rise and fall freely, and when raised, at least the window 1
Since the movable heat insulating plates 5 and 15 are arranged to cover the lower half of the room I from the inside, the indoor room I can be heated only by solar heat as described above. Furthermore, during heating, the outside of the waist wall main body 2 can be covered with a heat insulating curtain 4, so that the heat stored in the heat storage body can be prevented from being radiated to the outdoors O. Furthermore, since at least the lower half of the window 10 can be covered with the movable heat insulating plates 5 and 15 during heating, the amount of heat radiated into the indoor I through the window 10 and into the outdoor O can be reduced. . Also window 1
Due to the existence of 0, not only can the waist wall portion where furniture cannot be placed inside be effectively used as a heating device, but also the room I can be heated from below to keep the feet warm. Further, since the waist wall main body 2 is made of a heat storage material and has the solar heat absorbing film 1 on its outer surface, it can sufficiently store the heat necessary for heating. Further, since the heating waist wall body itself becomes a part of the building wall, additional equipment is unnecessary. Furthermore, when heating the indoor room I is not necessary, such as in summer, if the waist wall main body 2 is covered with a heat insulating curtain 4, heat will not be stored in the heat storage body.
