That is, in the air circulation building of this embodiment, the entire area under the floor is used as a common air circulation space throughout the building, and the air is circulated from the underfloor space to the inner surface of the wall and the inside of each room.

It is sufficient that the upright wall portion 22 has a sufficient space to allow air to flow under the floor. In the embodiment, however, the foundation concrete portion 20 is positioned lower than the ground 24 and the upright wall portion is provided. The underfloor space 25 is made wider than the conventional building by making the height of the space 22 relatively large. The base concrete section 20 is formed by casting concrete on the entire lower surface of the floor, thereby preventing moisture from entering from under the floor. Further, the foundation concrete portion 22 is provided with a constant thickness so that a suitable heat storage effect can be obtained by the foundation concrete portion 22.

In addition, the air inlet 40 in each room and the heat exchange ventilation fan 42 are all communicated by a duct 44 so as to communicate with the heat exchange ventilation fan 42. In addition,
The heat exchange ventilation fan 42 is installed in a space above the ceiling 38 and below the heat insulating material 10a.

Reference numeral 50 denotes an outside air introduction duct. The outside air introduction duct 50 is installed with one end protruding from the outer wall surface of the building so as to be opened, and is arranged so as to pass through the heat exchange ventilation fan 42, and inside the heat exchange ventilation fan 42, the outside air and the exhaust from each room are exchanged. Heat exchange and underfloor space 2
5 and the other end is extended to open in the underfloor space 25.
Thereby, the outside air is introduced into the underfloor space 25 via the outside air introduction duct 50.

The heat exchange ventilation fan 42 is provided with a fan for exhausting air from each room, and by driving the fan, the air is passed to form an air cycle for ventilation. The heat exchange ventilation fan 42 having a total heat exchange action is used. Total heat exchange involves simultaneous exchange of both temperature and humidity between the exhaust air and the outside air, and the temperature and humidity are reduced by alternately connecting thin tubes through which the exhaust air and the outside air flow and allowing the exhaust air and the outside air to flow through each other. Can be exchanged.

The heat exchange by the heat exchange ventilation fan 42 is performed by the correlation between the temperature and humidity between the outside air and the exhaust air. If the outside air is cold in the winter period, the outside air is warmed and introduced into the building, and the summer period. When the outside temperature is high, it acts to cool the outside air and introduce it into the building. For example, when the outside air is 0 ° C. and the humidity is about 80% in the winter period, if the outside air is warmed to about 20 ° C. by simple heat exchange, the humidity becomes 3%.
Although the humidity becomes considerably low such as 0%, the humidity is exchanged between the exhaust air and the outside air by total heat exchange, and the humidity becomes 40 to 50.
% Of the living environment.

In this embodiment, in order to effectively exchange the humidity between the exhaust air and the outside air during the total heat exchange, the exhaust air from each room is collected in the heat exchange ventilating fan 42, and the bathroom or the washroom is used. Exhaust gas is also collected in the heat exchange ventilation fan 42 from a room where high humidity is likely to be generated, and the total heat exchange is performed. Since a large amount of humidity is generated in a bathroom or the like, a large amount of dew condensation or the like is generated in a normal building. Even if the exhaust gas is returned to the apparatus, effective heat exchange can be performed without affecting the apparatus.

As described above, the air circulation building according to the present embodiment is provided with an air circulation system for taking in outside air into the building, exchanging heat between the air in the building and the outside air, and exhausting the air from inside the building. It is composed. Looking at the flow of air in this air circulation cycle, the outside air introduced from the outside air introduction duct 50 is subjected to total heat exchange with the air discharged from each room of the building by the heat exchange ventilation fan 42, and then the outside air introduction duct 50 Through the underfloor space 25. The outside air is released in the underfloor space 25 and is accumulated in the underfloor space 25, and then rises from under the floor toward each room. In the underfloor space 25, the base concrete portion 20 is heated in winter by the heat storage action or humidity adjustment action, and is cooled in summer and supplied to each room.

In the case where air flows from the underfloor space 25 into each room, as shown by arrows in the figure, the openings 3 pass through the air flow path 34 formed between the heat insulating material 10 and the inner wall 32 from under the floor.
6 to each room. As described above, the air is raised from the lower side of the air flow path 34 along the heat-insulating boat 10 so that the air is brought into contact with the inner wall portion 32 and the pillar material so that the air can be well mixed with each member. That's why. In this way, the air is not supplied directly to each room from under the floor, and the air is circulated so as to wrap around the entire building, so that the entire building can be properly ventilated and the building can be made to last longer. Insulation material 1
Since the respective chambers are effectively insulated from the outside by the action of 0 and 10a, the cooling and heating in the room can be performed very efficiently.

After the air supplied to the room is returned to the room, the air is supplied from the air inlet 40 through the duct 44 to the heat exchange ventilation fan 4.
It is exhausted to 2. In the heat exchange ventilation fan 42, the outside air and exhaust gas are totally heat-exchanged as described above. If the outside air is cold, the outside air is warmed, the outside air is introduced at a required humidity, and if the outside temperature is high, the outside air is cooled. When the humidity is high, it acts to reduce the humidity and introduce outside air. After passing through the heat exchange ventilation fan 42, it is discharged from the exhaust duct 46 to the outside. In this way, an air circulation that takes in outside air is formed, and ventilation of the entire building is performed.

As described above, the air circulating building of the embodiment is constructed such that each room is thermally shielded from the outside by the heat insulating materials 10 and 10a. Due to the hermetic structure, it is possible to provide ventilation so as to wrap the whole building, and it is possible to obtain suitable ventilation and indoor environment throughout the building throughout the season. Thereby, the cooling and heating effect in each room also works effectively, and the running cost for cooling and heating can be reduced effectively.

FIG. 2 shows an example in which solar heat is used for indoor heating. The heat insulating material 1 of the building of this embodiment is the same as the above embodiment.
0 indicates that the outer wall, ceiling, etc. of each room are wrapped around and insulated from the outside and shut off. Numeral 60 is a solar heat collecting part installed on the roof, 62 is a heat radiating part installed on the foundation concrete part 20, and 64 is a hot water supply part.
A circulation path for circulating the heat medium is provided between the heat radiating section 62, the hot water supply section 64, and the heat collecting section 60.

Normally, a hot water supply unit 60 utilizing solar heat is generally used. However, in this embodiment, a heat radiating unit 62 utilizing solar heat is installed in the underfloor space 25 to enable hot water supply and indoor heating. It is characterized by having done. By controlling the flow path of the heat medium between the hot water supply unit 64 and the heat radiating unit 62 by a switching valve, hot water supply, heat radiation, or both can be used. The heat radiating section 62 can be suitably used for indoor heating in winter or the like.
By installing 2, the entire base concrete section 20 can be warmed, and the air in the underfloor space 25 can be entirely warmed by the heat storage effect of the base concrete section 20.

As described above, in the air circulation building according to the present invention, the outside air is once introduced into the underfloor space 25, and the temperature and humidity are adjusted in the underfloor space to supply air to each room. Also in the case of utilizing solar heat as in the present embodiment, effective indoor heating can be performed by providing the heat radiating portion 62 in the underfloor space 25 to warm the air in the underfloor space.
