Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a solar heating building that can effectively heat indoor rooms using solar heat.

[Technical background of the invention and its problems]

Recently, the use of solar heat has attracted attention from the viewpoint of energy saving, and various solar heat-utilizing buildings have been proposed that use the solar heat to heat indoor rooms.

That is, FIG. 1 is a partially cutaway perspective view schematically showing the above-mentioned solar heating building, in which a transparent plate 1 such as glass that transmits solar heat is attached to a part of the outer wall. On the indoor side of 1, a space 2 is provided, and a heat storage wall 3 such as a concrete wall is provided in parallel with the transparent plate 1.

When the sun shines during the day, the heat storage wall 8 is gradually warmed from the space 2 side by the solar heat that comes in through the transparent plate 1 and the space 2, and the entire wall reaches a high temperature by evening. Therefore, this heat is released into the room by radiation and natural convection, heating the room.

FIG. 2 is also a principle diagram showing the method of heating a building using solar heat, in which hot air heated in a greenhouse 4 is heated by solar heat coming in through a transparent plate 1 such as a glass window. The heat flows into a heat storage tank 6 disposed under the floor, is stored there, and is radiated into the room 8 via the floor surface 7.

However, the systems shown in the above figures do not use a blower in either case, so there is no need for power costs, but there are problems in that the heating performance is not necessarily sufficient.

On the other hand, as shown in FIG. 3, heat from the sun is received by a heat collector 9 installed on the roof, and the warm air obtained by the heat collector 9 is sent under the floor by a first blower 10. The heat is supplied to the heat storage tank 11 provided, and the heat is stored in the heat storage tank 11. During heating, the second blower 12 is driven to circulate indoor air to the heat storage tank 11, and the air whose temperature has risen there is used for air conditioning. There is also a system in which the air is supplied to the room 16 from the outlet 15 through the duct 13 to heat the room.

However, although the performance is sufficient in this case, there are inconveniences such as high equipment costs and high running costs because it is necessary to install two blowers 10 and 12, an air conditioning duct 13, etc. .

[Purpose of the invention]

In view of these points, it is an object of the present invention to provide a solar thermal building that combines heat storage walls, heat storage tanks for floor heating, etc., and is capable of reducing running costs and improving heating performance. .

[Summary of the invention]

The present invention provides a first greenhouse that is formed by a space between a transparent plate that transmits solar heat and a heat storage wall that is arranged on the indoor side of the transparent plate, and that is provided on one side wall of a building and a ceiling. a second greenhouse having a skylight arranged in the section and communicating with the first greenhouse via a damper; a heat storage tank for floor heating that is communicated with a second greenhouse and whose other end is communicated with the first greenhouse through a communication port, and a damper is provided in each of the hot air passage and the communication port. It is characterized by

[Embodiments of the invention]

FIG. 4 is a diagram schematically showing the solar thermal building of the present invention, in which on the base 20 having heat insulation properties,
Hot air inlet plenum 21 and hot air outlet plenum 2
A heat storage layer 23 consisting of a large number of frame stones is filled between the two,
A heat storage tank 25 with a floor surface 24 placed on its upper surface is disposed.

On the other hand, a transmitting plate 26 such as glass that transmits solar heat is installed on a part of the side wall over its entire height, and a heat storage wall 27 such as a concrete wall is provided on the indoor side of the transparent plate 26. A first greenhouse 28 is formed between the heat storage wall 27 and the transmission plate 26.

In addition, a second greenhouse 3 has a skylight 29 equipped with a transparent plate made of glass or the like that transmits solar heat on the roof.
0 is provided, and the second greenhouse 30 and the first greenhouse 28 are communicated via a damper 31. Further, the second greenhouse 30 is connected to the hot air inlet plenum 21 via an air guide pipe 32, and the air guide pipe 32 is provided with a blower 33, and the inlet portion of the warm air inlet plenum 21 is connected to the second greenhouse 30. Dampers 34 and 35 are provided at the outlet portions of the ventilation outlet plenum 22, respectively. Further, a blind 36 is provided inside the transparent plate 26 of the first greenhouse 28, and a louver 37 is provided outside the skylight 29 of the second greenhouse 30.

Thus, daytime sunlight passes through the transmission plate 26 and the skylight 29 and enters the first greenhouse 28 and the second greenhouse 3.
When the solar heat enters the first greenhouse 28, the heat storage wall 27 is heated and heat is gradually stored therein, and the air inside the greenhouse 28 is heated. Furthermore, the air within the second greenhouse 30 is also heated by solar heat. Therefore, when the blower 33 is driven, the hot air in both greenhouses 28 and 30 passes through the air guide pipes 32 in turn, and from the hot air inlet plenum 21 to the heat storage layer 2.
3, and while the hot air flows through the heat storage layer 23, the heat of the hot air is stored in the heat storage layer 23. Further, the air leaving the heat storage layer 23 is returned to the first greenhouse 28 via the hot air outlet plenum 22.

On the other hand, when heating the room, each damper 31, 3
4 and 35 are closed, the blower 33 is stopped, and the heated air in the first greenhouse 28 and the second greenhouse 30 is prevented from flowing. Therefore,
The air flow flowing along the surface of the heat storage wall 27 toward the second greenhouse 30 prevents heat from being removed from the surface of the heat storage wall 27, and the first greenhouse 2
The heat storage wall 27 is heated by the heated air of 8, and the heat is stored in the heat storage wall 27. The heat stored in the heat storage wall 27 is radiated into the room from the back surface thereof, and the room is heated by natural convection of indoor air in contact with the back surface. In addition, natural convection of air occurs in the heat storage tank 25 disposed under the floor due to the heat storage in the heat storage layer 23, and the heat from the warm air is radiated into the room through the floor surface 24, and the indoor floor heating is performed. It is done. In addition, during heat dissipation at night, by closing the blind 36 provided inside the transparent plate 26 of the first greenhouse 28 and the louver 37 provided in the skylight 29, heat dissipation from the relevant portion to the outdoors is prevented. to improve insulation performance.

FIG. 5 is a sketch showing the three-dimensional arrangement of the solar heating building shown in FIG. Heat can be radiated to the chambers provided on the left and right sides of 28. Also, the first
The hot air obtained in the greenhouse 28 and the second greenhouse 30 passes through the air guide pipe 32 and is sent by a blower to the heat storage tank 25 disposed under the floor of the room, where the heat is stored and the heat storage layer is The warm air coming out of 25 is returned into the first greenhouse 28 through an outlet 38. Furthermore, it goes without saying that solar heat is taken into the building through ordinary windows 39a, 39b, 39c, and 39d.

[Effects of the Invention] As explained above, in the present invention, heat is stored in the heat storage wall in the first greenhouse, and the first greenhouse
Heat is stored by collecting and heating hot air in the greenhouse and the second greenhouse and sequentially sending it to a heat storage tank installed under the floor.When heating, the heat released from the heat storage wall and The room can be heated by both the heat released from the heat storage tank through the floor surface, and the heating efficiency can be improved. In addition, forced air is only used when storing heat, and heat is radiated from the heat storage tank through the floor during heating, so there is no need to install two blowers or air conditioning ducts.
It is possible to significantly reduce equipment costs and running costs.
