Description

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

As a prior art, there is a solar heating device with an outside air cooling device as described in Japanese Patent Application Laid-Open No. 153443/1983. This device has openings for outside air intake or exhaust on the top and bottom of the outside of a solar heat collection box installed on the outside wall of a building, and openings on the top and bottom of the inside, and these openings are equipped with opening/closing devices. Thereafter, just a blind is placed in front of the wall with an airflow gap in between. The rear wall is said to have heat insulation or heat storage properties as needed. Therefore, if the back wall has heat insulation properties, the solar heating system cannot be expected to have heat storage properties, and on the other hand, if the back wall has heat storage properties, the solar heat captured by the blinds will Because heat is stored in the rear wall, there is a problem that the room becomes hot in the summer.

The purpose of this invention is to provide a heating wall that solves the above problems.

In order to achieve the above-mentioned purpose, the heating wall according to this invention consists of a frame-shaped peripheral wall that is fitted into an opening made in a building wall, and a heat storage body that has a transparent top plate and a solar heat absorption film on the front surface. with a double front wall,
It consists of a rear wall arranged with an air circulation gap behind the heat storage body in the front wall, and an upper communication opening and a lower communication opening are provided at the upper and lower parts of the rear wall to connect the air circulation gap and the indoor space. The rear wall is made of a heat insulating material.

In this specification, "front" refers to the outdoor side, and "rear" refers to the indoor side.

As the transparent top plate, a transparent glass plate is generally used, but transparent synthetic resins such as acrylic resins can also be used. 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 with water or latent heat storage material in the concrete. Suitable latent heat storage materials include sodium sulfate decahydrate, calcium chloride hexahydrate, sodium phosphate dodecahydrate, caustic soda monohydrate, sodium thiosulfate pentahydrate, paraffin, and polyethylene glycol.
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 promote heat dissipation, it is better to paint the rear surface of the heat storage body white or black, or to attach a metal plate such as an aluminum plate. As the heat insulating material for the rear wall, glass wool or synthetic resins such as urethane and styrene are used. During seasons when heating is not required, an insulating shutter is placed further forward on the front wall of the case. The insulation shutter is
It can be detachable from the case, or it can be a hinged type,
It may be in the form of a sliding door, or it may be a shutter or blind that moves up and down. Furthermore, a canopy may be provided on the upper side of the case instead of the shutter. It is preferable to provide a blower fan on the lower communication opening side so that warm air can be supplied from the lower side of the room.

An embodiment of this invention will be described below with reference to the drawings.

The illustrated solar heating wall body includes a frame-shaped peripheral wall 3 that is fitted into an opening 2 formed in a building wall 1;
A double front wall 7 composed of a transparent top plate 4 and a heat storage body 6 having a solar heat absorbing film 5 on the front surface, and an air circulation gap 9 placed behind the heat storage body 6 of the front wall 7. An upper communication port 10 and a lower communication port 11 are provided at the upper and lower parts of the rear wall 8 to communicate between the air circulation gap 9 and the indoor space.
is made of a heat insulating material.

The case peripheral wall 3 is made of extruded aluminum and is suitably insulated. An air layer 12 is formed between the transparent top plate 4 and the solar heat absorbing film 5 to improve the heat retention effect. The solar heat absorption film 5 is a solar heat selective absorption film formed by treating the front surface of an aluminum foil with a solar heat selective absorption film, and this aluminum foil is attached to the heat storage body 6 with an adhesive or an adhesive. The heat storage body 6 is made up of a large number of watertight spherical containers 6b the size of ping pong balls scattered within concrete 6a. A black coating film 13 is formed on the rear surface of the heat storage body 6. In the lower communication port 10,
An intake port 15 with a movable louver 14 is provided. The lower communication port 11 is provided with an exhaust port 17 having a blower fan 16 . In the figure, 18 is a ceiling, 19 is a floor, and 20 is a sliding door.

Next, the function of the heating device wall will be explained.

During the day, sunlight S from the outdoor O is transmitted through the transparent top plate 4.
and hits the solar heat absorbing film 5. the result,
Sufficient heat is stored in the heat storage body 6 with the help of the solar heat absorbing film 5, which absorbs heat well but emits little heat. The heat stored in the heat storage body 6 is radiated to the air layer within the air circulation gap 9.
The heated air is supplied to the lower part of the room from the exhaust port 17 through the lower communication port 11 by driving the blower fan 16 . On the other hand, indoor air flows into the air circulation gap 9 from the intake port 15 through the upper communication port 10. Indoor and air circulation gap 9
In this way, air circulates between the two and heats the room. Heating continues at night due to the action of the heat storage body 6.

Although not shown, the exhaust port 17 is provided with a damper, so that both the ports 15 and 16 are closed together with the louver 17 of the intake port 15 in the summer.

In addition, although the ventilation fan is provided in the above embodiment, this may not be necessary. In this case, the heated air in the hollow portion flows from the bottom to the top, so the exhaust port in the above embodiment is changed to an intake port, the intake port is changed to an exhaust port, and the air circulation path is reversed.

According to the solar heating wall body of this invention, since the heat storage body is provided with the solar heat absorbing film on the front side, it is possible to sufficiently store the heat necessary for heating. In addition, the solar heat absorption film is covered with a transparent top plate.
Since it is not exposed outdoors, there is no risk of damage and is durable. Also, this heating wall is equipped with a frame-shaped peripheral wall that fits into an opening in a building, so it can be used as a heating wall in a building. Easy to fit into wall openings and easy to install. Furthermore, the rear wall is made of insulating material, so the interior will not heat up in the summer.
