Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat storage wall that forms the outer wall of a building and allows solar heat to be used for indoor heating.

Conventionally, as shown in, for example, Japanese Patent Application Laid-open No. 58-55691, "a heat collection plate and a heat storage plate are arranged facing each other, a heat pipe is connected from the heat collection plate to the heat storage plate, and the evaporation part of the heat pipe is collected. A heat storage wall has been proposed that is connected to a heat plate and has a condensing section connected to the heat storage plate, and is arranged so as to rise and slope from the heat collection plate toward the heat storage plate. According to the heat storage wall already proposed above, the heat collected in the heat collecting section is transported and stored in the heat storage body using a heat pipe, and the heat stored in the heat storage body is radiated indoors at night when the room temperature drops. becomes possible.

However, in the heat storage walls already proposed above, the heat storage body is installed indoors, so when the weather is bad and the heat storage body is cold, the room cannot be heated using other heat sources. In this case, the amount of heating heat in the room is absorbed by the cold heat storage body, which inhibits the rise in room temperature, that is, the start-up characteristics of heating.

An object of the present invention is to provide a heat storage wall that does not inhibit the startup characteristics of indoor heating using heat sources other than solar radiation.

In order to achieve the above object, the heat storage wall according to the present invention has a heat collecting part facing the outdoors and a heat radiating part facing the inside facing each other in a separated state, and a heat storage body is provided in contact with the inner surface of the heat collecting part. , a heat insulator is provided between the heat storage body and the heat radiating part, the heat storage body and the heat radiating part are connected by a heat pipe, and the heat pipe is arranged to rise and slope from the heat storage body toward the heat radiating part. It was designed so that

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, a heat storage wall 12 is built into the south side of the building 11 to form an outer wall.

The heat storage wall 12 has a heat collection part 13 facing the outdoors and a heat radiating part 14 facing the inside, which are arranged to face each other in a separated state, and a heat storage body 15 is provided in contact with the inner surface of the heat collection part 13, so that the heat storage body 15 and the heat radiation part A heat insulating body 16 is provided between the parts 14 and 14. The heat storage body 15 is made of a material with a large heat capacity such as concrete, brick, or a phase change substance such as sodium sulfate, and the heat insulator 16 is made of a heat insulating material such as glass wool.

Furthermore, the heat storage wall 12 has a built-in heat pipe 17 as shown in FIGS. through the condensing section 1
7B is connected to the heat radiation section 14. The heat pipe 17 is connected from the heat collecting section 13 to which the evaporating section 17A located on the lower side is connected, to the heat dissipating section 14 to which the condensing section 17B located adjacent to the upper side of the evaporating section 17A is connected. It is arranged so that it rises and slopes towards the side of the building. Further, the heat pipe 17 is also tilted upward in the evaporating part 17A connected to the heat collecting part 13 and the heat storage body 15, and in the condensing part 17B connected to the heat radiating part 14. That is, the heat pipe 17 is arranged in the above-mentioned upright and inclined state, allowing only heat transfer from the heat collecting section 13 and the heat storage body 15 toward the heat radiating section 14, and can prevent heat transfer in the opposite direction. Therefore, heat transfer by the heat pipe 17 of the heat storage wall 12 can be restricted only in one direction from the outdoor side to the indoor side.

In the above embodiment, a cover 18 made of glass or transparent plastic is provided on the outermost surface of the heat storage wall 12 to suppress heat radiation from the heat storage body 15 to the outside.

In addition, in the above embodiment, in order to prevent heat from entering the room during the summer when heating is not required, awnings that reflect light well, insulated doors, etc. are provided, and the upper and lower parts of the heat storage wall 12 are installed. The air in the space formed by the cover 18 and the heat storage body 15 may be evacuated by providing an intake/exhaust opening that can be opened and closed.

Next, the operation of the above embodiment will be explained.

During the day, solar heat collected in the heat collecting section 13 is stored in the heat storage body 15. as in the night,
When the indoor temperature decreases and the difference between the indoor temperature and the temperature of the heat dissipation section 14 becomes large, the heat stored in the heat storage body 15 is efficiently transferred to the heat dissipation section 14 by the heat pipe 17, and then the heat is transferred indoors. , allowing indoor heating.

However, in the above embodiment, the heat storage body 15
Because the heat insulator 16 is arranged on the indoor side of the room, even when the room is heated by another heat source when the weather is bad and the heat storage device 15 is cold, the amount of heating heat in the room is reduced. Heat is not absorbed by the cold heat storage body 15, and the heating start-up characteristics are not inhibited.

As described above, in the heat storage wall according to the present invention, the heat collection part facing the outdoors and the heat radiating part facing the room are arranged facing each other in a separated state, and the heat storage body is provided in contact with the inner surface of the heat collection part. A heat insulating body is provided between the heat storage body and the heat dissipation part, the heat storage body and the heat dissipation part are connected by a heat pipe, and the heat pipe is arranged to rise and slope from the heat storage body toward the heat dissipation part. This is what I did. Therefore, according to the present invention,
The start-up characteristics of indoor heating using heat sources other than solar radiation are not inhibited.
