Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention configures the entire space of an air cycle house into one closed space, forcibly generating an air flow in this space, and at the The present invention relates to a house in which fresh air is inhaled in a heat-exchanged state and the heat in the house can be quickly released to the outside in the summer.

[Conventional technology]

Houses of this kind of structure either had an air cycle only by natural ventilation, or had one forced circulation device interposed in this structure.

[Problems to be Solved by the Invention]

However, if the air cycle house with the previous configuration only heats a limited room, such as during the winter,
The entire house was not air cycled. This is because the interior wall surface and ceiling of a house and the shoji on the corridor side are heated by only one room in the house, and only the internal space in this part rises in temperature, which causes an air cycle for the entire house. However, there is a drawback in that the warm air that has risen is cooled to a certain height by other cold air, the rise stops, and dew condensation occurs. Of course, since the stove and the like are on the floor, in the air cycle space in the vicinity, dew condensation is immediately caused by contact between cold air in the underfloor space and the like and air heated at high humidity by the stove and the like.
It had the drawback of accelerating the corrosion of the base and the heat insulating material (wetting the glass wool with a rag).

[Means for solving the problem]

In view of such a point, the present invention aims to reduce the heat loss by forcibly causing the air flow in the house and performing intake and exhaust to the house through the heat exchanger in the winter season. In addition, the heat efficiency is improved by using the air in the attic space as the air for heat exchange, and in the summer, the supply pressure by intake of outside air into the underfloor space and the rising force of warm air are used. We propose a house that can be quickly discharged from the space behind the hut to the outside through the air vent of the hut.

〔Example〕

An embodiment of a house according to the present invention will be described in detail below with reference to the drawings. 1 (a) and 1 (b) are functional explanatory views showing only a main part of a house A according to the present invention.
Is an attic space, 2 is a living space, 3 is an underfloor space, and 4 is an inner / outer wall space. That is, the attic space 1, the living space 2, the underfloor space 3, and the inner and outer wall spaces 4 are spaces inside the house A,
The attic space 1 and the underfloor space 3 are connected by an inner and outer wall space 4. To further explain, the inner / outer wall space 4 is a space formed by one layer or a plurality of layers between the inner wall 5 and the outer wall 6. As shown in FIGS. 1A and 1B, the inner / outer wall space 4 has one layer. In such a case, the outer wall 6 may be formed into an outer heat insulating structure using a heat insulating material, or as shown in FIG. 2, the inner and outer wall spaces 4 may be two layers or more, and the outer wall 6 may be a heat collecting wall such as mortar. And the passing air cycle. The inner wall 5 is made of one type of gypsum board, mortar wall, wood board, concrete or the like. The underfloor space 3 is a space from the soil floor 7 to the floor 8, and is provided with a heat exchanger 9 and also functions as an air dam of the fresh air supplied through the heat exchanger 9, and also serves as a house. It is also useful for uniformly sending air into A. The heat exchanger 9 is, for example, as shown in FIGS. 3 (a) and 3 (b), and discharges the air in the house A and supplies the outside fresh air into the house A in the winter. ,
At this time, heat is exchanged between both air to reduce energy loss. To further explain, the heat exchanger 9 is connected via the underfloor ventilation port 10 and the fan 11,
It is connected to the attic space 1 by a pipe 12.
That is, the underfloor ventilation port 10 includes the ventilation port 10a for intake and the ventilation port 10b for exhaust, and the ventilation port 10a and the duct of the heat exchanger 9.
The duct 9b of the heat exchanger 9 and the ventilation port 10b are connected to each other via the fan 11. The pipe 12 is connected to the duct 9d of the heat exchanger 9, and the duct 9c is formed so as to discharge air to the underfloor space 3. In this case, fresh air outside is taken in by the fan 11 from the ventilation port 10a, flows through the ducts 9a to 9c of the heat exchanger 9, and is dispersed in the underfloor space 3. On the other hand, the air in the attic space 1 passes through the pipe 12 and passes through the heat exchanger 9
It moves from the duct 9d to 9b and is discharged to the outside through the ventilation port 10b. At this time, heat is exchanged in the heat exchanger 9, and fresh outside air is warmed by the air discharged from the attic space 1 to the outside and then dispersed in the underfloor space 3. It is also possible to use the underfloor ventilation port 10 with a built-in fan 11. Also pipe
A fan 13 is arranged at 12 to forcibly supply the air in the attic space 1 to the heat exchanger 9. Therefore, in the house A, a flow of air from the underfloor space 3 to the attic space 1 is reliably generated. Reference numeral 14 is an attic ventilation port and at least 1 is provided in the attic space 1.
More than one is provided, and heat in the house A in the summer,
It is for releasing moisture. This attic vent 14
Has at least an opening / closing device (not shown), and has a function of blocking the heat in the house A in the winter season so as not to release the heat. If necessary, an attic ventilation fan can be provided in the attic ventilation opening 14 to forcibly discharge the warm air rising in the attic space 1 to the outside in the summer.

Here, regarding the air flow in the house A, FIG. 1 (a),
This will be described with reference to FIG. FIG. 1 (a) shows the flow of air in the winter by arrows, in a state where the fans 11 and 13 are operated and the attic ventilation opening 14 is closed. In this condition, fresh outside air will be vented to the vents 10 of the underfloor vents 10.
It is forcibly taken in by a fan 11 from a and is supplied to the underfloor space 3 via a heat exchanger 9. The air released to the underfloor space 3 rises in the inner and outer wall spaces 4 and the living space 2 due to the supply pressure and the suction force in the attic space 1, and enters the attic space 1 together with the heat generated in the living space 2. Reach The air in the attic space 1 is sucked by the fan 13, passes through the pipe 12 and the heat exchanger 9, and is discharged to the outside from the ventilation port 10b of the underfloor ventilation port 10. At this time, heat is exchanged with the air taken in from the outside via the heat exchanger 9, and the heat loss in the house A can be greatly reduced. Also the first
Figure (b) shows the flow of air in the summer, in which the attic ventilation opening 14 is opened, and the fan 13 and the fan 11 connected to the exhaust ventilation opening 10b are stopped. . In this case, outside fresh air is taken in by the fan 11 from the ventilation opening 10a of the underfloor ventilation opening 10, and the heat exchanger 9
And is discharged to the underfloor space 3. On the other hand, attic space 1
Then, air is released to the outside through the attic ventilation opening 14. For this reason, in the inner and outer wall spaces 4 and the living space 2, the rising force of the heating by the sunlight causes the underfloor space 3 to the attic space 1
A flow of air to the house A is released, and heat and humidity are released from the attic ventilation opening 14, and the living space 2 is cooled by the cool air and fresh air in the underfloor space 3.
In this case, since the heat exchanger 9 functions only as a duct that does not perform heat exchange, the air discharged to the underfloor space 3 remains as the outside cold air, and the cool house A
Becomes

What has been described above is only one example of the house A according to the present invention, and FIGS. 4 (a) to (d) to the soil floor 7 of the underfloor space 3 are shown.

In particular, in the case of the dispersion pipe 15 shown in FIGS. 5 (a) and 5 (b), since the void of the communicating tissue serves as the slit 15a, it is assumed that air is released at equal pressure in any part of the dispersion pipe 15. Become. Furthermore, lay crushed stones on the dirt floor 7,
It can also function as a heat storage material in winter and a cold heat material in summer. Further, the air collection duct 16 having the same shape as the dispersion pipe 15 shown in FIGS. 4 (a) to (d) to FIGS. 6 (a) and (b), or a trumpet-like air collecting duct 16 is disposed in the attic space 1. It is also possible to connect with the pipe 12. Moreover,
It is also possible to dispose a fan (not shown) in the inner and outer wall spaces 4 to promote a smoother air flow. Moreover, it is also possible to install temperature sensors, humidity sensors, smoke sensors, etc. in the attic space 1, the living space 2, the underfloor space 3, and the inner and outer wall spaces 4 to control the attic ventilation opening 14, fans 11 and 13. is there.
It is also possible to provide intake / exhaust ports on the floor 8, the inner wall 5, and the ceiling so that the living space 2 also serves as one path of the air cycle. In addition, it is possible to dispose a moisture-proof sheet or an anti-termite sheet on the soil 7.

〔The invention's effect〕

As described above, according to the house of the present invention, the cool air in the underfloor space and the fresh air outside are circulated in the summer, so that the living space is cool and has a good habitability.
There is little heat loss because the outside fresh air is supplied to the underfloor space while being warmed by the heat exchanger. The forced air cycle ensures that the air cycle is performed and the effect can be obtained. Since air moves even in the inner and outer wall spaces, it is possible to prevent the formation of dew condensation and also the formation of mold and mites. The air in the living space is fresh air from the outside and is hygienic. The heat exchanger is commonly used to reduce heat loss due to heat exchange in winter and to release fresh air to the underfloor space as it is in summer, so that the facility cost can be reduced. The air that is heat-exchanged and released to the outside is air in the attic space that is not normally used, so that the thermal efficiency is improved. There are effects and features such as.
