Next, the mode of ventilation in the building will be described with reference to the drawings.
The building body 1 of the present embodiment is provided with the 24-hour ventilation type air conditioning equipment as described above, and this air conditioning equipment is in operation.

  First, in a warm season such as summer, as shown in FIGS. 1, 6 and 7, the opening / closing means 23 b for opening and closing the vent 23 a is in a state in which the vent 23 a is opened. The intake fan 21 rotates and draws air from the outside to the wind tunnel portion 20, and the blower fan 25 sends the air in the main pipe 24 a to the ventilation tower 22, that is, below It is in a state of rotating in the direction from the top to the top.

  Therefore, the wind tunnel part 20 can take in relatively cool air from the lower end part and send it to the upper end part. And the air rising to the upper end part of the wind tunnel part 20 will be discharged | emitted from the vent hole 23a of the said ventilation tower 22 to the outdoors, The state in which the inside of the said wind tunnel part 20 has always generated ascending airflow, Become.

Further, since the blower fan 25 sends the air in the main pipe 24a from below to above, the relatively cold air at the lower end of the wind tunnel portion 20 is shown in FIGS. It can supply to each said living area through the said subpipe 24b.
Further, the relatively cool air supplied to each living area is warmed in each living area, collected near the ceiling of each living area, and then discharged to the wind tunnel portion 20 through the exhaust port 26. The
The air exhausted to the wind tunnel portion 20 rises to the upper end portion of the wind tunnel portion 20 due to the property that warm air rises and the above-described ascending air current, and goes outside from the vent hole 23a. It is supposed to be discharged.

  Further, the cool air of the air taken into the wind tunnel portion 20 by the intake fan 21 is caused by the heat storage means 27 provided in the underfloor space of the floors 2a and 2b and the heat storage means 27 provided in the underfloor space of the floor 3a. The heat is stored, and the cooling effect on each living area on the floors 2a, 2b, 3a can be exhibited. In particular, it is easy to store cold air at night.

  Moreover, ventilation efficiency can be improved also by opening the opening part and skylight 5 which were provided in each said living area.

  On the other hand, in a cold season such as winter, as shown in FIGS. 2, 6, and 7, the opening / closing means 23 b that opens and closes the vent 23 a is in a state of closing the vent 23 a, The intake fan 21 is stopped, and the blower fan 25 rotates in the direction of sending the air in the upper end portion of the wind tunnel portion 20 and the ventilation tower 22 into the main pipe 24a, that is, in the direction from above to below. It is in a state to do.

Therefore, the wind tunnel portion 20 is isolated from the outdoors, and only the blower fan 25 is in operation. Especially on a sunny day, the air at the upper end of the wind tunnel 20 is warmer than the air at the lower end, so that warm air can be sent to each of the living areas and the heat storage means 27 and 27. At night, the air in the wind tunnel portion 20 can be warmed by the warm air in each living area and the hot air emitted from the heat storage means 27, 27. It can be sent into the main pipe 24a.
In addition, even in cold seasons such as winter, the nature of warm air rising does not change, so the warmer the air in the wind tunnel portion 20 rises.

  Also, since the blower fan 25 sends the air in the upper end of the wind tunnel 20 and the ventilation tower 22 into the main pipe 24a, the warm air at the upper end of the wind tunnel 20 is shown in FIGS. As shown, it can be supplied to each living area through the sub-pipe 24b.

Further, the warm air supplied to each living area is collected in the vicinity of the ceiling of each living area as it is, or is further heated and then collected in the vicinity of the ceiling, and is discharged from there through the exhaust port 26 to the wind tunnel portion 20. Is done.
And the air discharged | emitted by this wind tunnel part 20 raises to the upper end part of the said wind tunnel part 20, and is again supplied by the said ventilation fan 25 to each living area.

  As described above, since the building body 1 is provided with a 24-hour ventilation type air conditioning system, the building body 1 can be used in a cold season such as winter as in the building ventilation structure of the present embodiment. Even if the inside air is circulated in the building main body 1, the air can be reliably ventilated for 24 hours.

According to the present embodiment, air is circulated between the wind tunnel portion 20 and the outside by the air circulation means to take air into the wind tunnel portion 20, and the air taken into the wind tunnel portion 20 is supplied to the air supply passage. The air is guided to the living areas by the air means, and the air in each of the living areas is discharged from the exhaust port 26 to the wind tunnel portion 20, and the discharged air is discharged outdoors by the air circulation means. Since it can be sent out, ventilation in the building can be performed.
Therefore, it is possible to increase the amount and speed of air in the air supply and exhaust in the building without increasing the power of the ventilator, so that it is possible to prevent an increase in cost and cool in the building in warm seasons such as summer. Can take.
Further, air is not circulated between the wind tunnel portion 20 and the outside by the air circulation means, but the air in the wind tunnel portion 20 is guided to the living areas by the air supply means, and these are supplied. Since the air in each living area can be discharged from the exhaust port 26 to the wind tunnel portion 20, the air can be circulated in the building.
Therefore, it is possible to prevent the cold outdoor air from being taken into the building and to discharge the warm air inside the building to the outside, so that it is possible to prevent an increase in costs, and in winter. The warming effect in the building can be enhanced in cold weather.
This makes it possible to form a comfortable living environment according to the season.

Moreover, since the said air distribution means is equipped with the said intake fan 21 and the said ventilation tower 22, it can take in air from the outdoors to the wind tunnel part 20 by operating the said intake fan 21, The air taken into the wind tunnel 20 can be discharged to the outside from the vent holes 23a of the ventilation tower 22.
Further, since the intake fan 21 is located at the lower end portion of the wind tunnel portion 20 and the ventilation tower 22 is located at the upper end portion of the wind tunnel portion 20, air flows from the lower end portion of the wind tunnel portion 20 to the upper end portion. It will move, and an updraft can be generated in the wind tunnel portion 20. Then, when such an updraft is generated in the wind tunnel portion 20, the air in each living area discharged from the exhaust port 26 to the wind tunnel portion 20 is put on the updraft to allow the ventilation tower 22 to pass through. The air can be efficiently discharged from the pores 23a to the outdoors. In addition, since warm air has the property of rising, ventilation efficiency is further improved particularly in warm seasons such as summer.
Further, since the vent hole 23a of the ventilation tower 22 is configured to be openable and closable, the air in the wind tunnel portion 20 can be surely discharged by closing the vent hole 23a, and the vent hole 23a is closed. Therefore, the generation of the rising air current in the wind tunnel portion 20 can be suppressed.

Further, since the air supply means includes the air supply pipe 24 and the blower fan 25, the air in the wind tunnel portion 20 is taken into the air supply pipe 24 by operating the blower fan 25. In addition, the air can be sent out to the living areas through the air supply pipe 24. Further, since the blower fan 25 is provided at the upper end portion of the air supply pipe 24, it becomes easy to take in warm air that accumulates in the upper portion of the wind tunnel portion 20 into the air supply pipe 24.
Thereby, in the cold season such as winter, warm air in each living area discharged from the exhaust port 26 to the wind tunnel portion 20 can be sent out again to each living area. Can be further enhanced.

  Further, the exhaust port 26 is disposed in the vicinity of the ceiling of each living area, and the tip of the air supply pipe 24 is in the vicinity of the floor 2b, 3a, 3b, 4a, 4b of each living area. Therefore, in a warm season such as summer, for example, relatively cold air can be taken into the living areas from below through the air supply pipe 24, and the warmed and raised air is taken into the exhaust port. 26 can be discharged to the wind tunnel portion 20. As a result, a cycle of ventilation in each living area can be formed, so that the inside of each living area can be efficiently ventilated.

Moreover, since the living area where the height of the floor 2a is set to be substantially equal to the ground surface among the living areas is open to the outdoors, the outdoor air is diverted to the living area. Can be captured. Moreover, since the air taken into the living area is not easily exposed to direct sunlight, the temperature is low even in a warm season such as summer.
In addition, since such relatively cool air can be drawn into the wind tunnel portion 20 by the suction fan 25, the lower portion of the wind tunnel portion 20 can be filled with relatively cool air.

Moreover, since the heat storage means 27 is provided in the underfloor space of at least one living area among the living areas, and the vent 20b is formed in the wall 20a, the wind tunnel portion is formed through the vent 20b. Warm air or cold air taken from 20 into the underfloor space can be stored in the heat storage means 27.
Thereby, the temperature of the floor of the living area located above the heat storage means 27 can be raised or lowered.

  Further, since the building body 1 is provided with a 24-hour ventilation type air conditioning facility, the air conditioning management in the building body 1 can be performed by this air conditioning facility. Moreover, it becomes possible to form a more comfortable living environment according to the season by using in combination with the ventilation function / air circulation function by the wind tunnel part 20.
