2. Description of the Related Art Conventional residential ventilation systems include:
There are a central ventilation system directly connected to ducts and a ventilation system using preheated air supply.The central ventilation system directly connected to ducts uses a gap in the air supply path and constantly exhausts air from a washroom, bath, toilet, etc. with a ventilation fan, or a duct. This is a ventilation system that discharges indoor polluted air by connecting to a chimney as a ventilation path. In addition, the preheating air supply ventilation system is mainly used for houses with basic insulation floors for cold districts. There are two types of outside air intake methods, a method using the underfloor space as an air supply path, and a centralized ventilation port There is a method of taking in outside air using a ceiling via a preheating room. In addition, both the indoor air circulation and the exhaust method are based on the control by a fan.

In the above two types of proposals, the duct-directed centralized ventilation system allows natural ventilation of the house, but does not use the structure of the building itself as ventilation equipment, and the duct is a ventilation path. Is connected from each room to the chimney, and the contaminated air from washrooms, baths and toilets, which are generally concentrated on the lower floors, is directly ducted from the exhaust port to the chimney, so duct members and duct space are required At the same time, the duct work becomes difficult and the installation cost becomes high.

[0004] Further, a ventilation system utilizing preheating air supply using an underfloor space as an air supply path cannot be used except for a basic insulated floor for cold regions, and it is necessary to secure a preheating room in a preheating room and a ceiling use method. Becomes Therefore, the planar freedom of the building is reduced due to structural restrictions. Furthermore, the air supply route is provided for warming measures in cold regions, and there is a problem that the utility is low in relatively warm regions south of the Tohoku region. The present invention focuses on such conventional problems. The purpose of the present invention is to use the structure of the building itself as a ventilation path, thereby rationalizing the ventilation equipment in each room, reducing the installation cost, and achieving a relatively warm environment. It can be installed in various areas.

In a building having the above-described structure, indoor air is sucked out of the chimney by buoyancy and wind force generated by a temperature difference between the inside and outside, and air is sucked out from the pit portion of the building and the exhaust grill of the second floor living room. Then, outside air is introduced from an air supply port on the lower floor. Therefore, the air in each room naturally goes to the chimney via the building pit or exhaust grill,
An effective natural ventilation house can be provided. Further, the final ventilation openings (7a) to (7d) to the outside are formed on the chimney side surface 4 and are not much affected by the wind direction, and since the wind flows along the roof, the suction effect by the negative pressure occurs. . FIGS. 3A to 3C show the results of actual measurement of the ventilation volume over 5 days using this structure. (A) is a graph showing an outdoor wind speed, (b) is a graph showing a comparison between an outside air temperature and an average room temperature, and (c) is a graph showing a chimney air volume (ventilation air volume) every hour. Thus, the ventilation air volume of the present application fluctuates with the fluctuation of temperature and wind speed (90 to 200 m 3 / h),
In addition, a generally required ventilation rate of 0.35 to 0.5 times / h (in the case of a house having a floor area of 120 m 2 ) is secured. Therefore, by using the building structure as in the present embodiment, it is possible to cover a necessary ventilation volume by natural ventilation.

As can be seen from this graph, Example 1
Insufficient ventilation in a light wind and suppression of ventilation in a strong wind, which could not be controlled only by the structure of the natural ventilation building, can be controlled by both the fan (10) and the damper (12). You can read it. In this embodiment, the fan (10) is adjusted to a range of 100 m 3 / h or more, and the damper (12) is adjusted to a range of 150 m 3 / h or less. As a result, as shown in FIG. 10, when the seasonal change is considered, the fan (10) and the damper (1) are provided throughout the year.
It is presumed that an optimal ventilation is obtained by using both of the above 2). Thereby, as shown in FIG. 10, it is estimated that the optimal ventilation is obtained by using both the fan (10) and the damper (12). In addition, the damper (12) automatically opens and closes during strong winds to suppress excessive ventilation according to the air volume at that time.
0) is automatically driven and the required ventilation volume is maintained, so that fine ventilation volume control (ventilation volume of 100 to 180 m 3 / h, which is generally considered to be the optimal range) is possible. It is also possible to increase the ventilation according to the resident's preference.

According to the present invention, each room is provided with an air supply port for introducing fresh air from the outside, an exhaust grill connecting the room and the back of the hut on the ceiling of each room on the upper floor, and a room on each lower room. By providing ventilation holes from each room to the ventilation holes using the pits, it is possible to make the ventilation volume of each room almost constant, and to use the building itself as a ventilation path, so natural ventilation at low cost Was made possible. In addition, by providing a chimney at the top of the building, it is possible to promote ventilation by utilizing the temperature difference between the inside and outside of the building and the suction effect of wind power. Furthermore, indoor air is collected in the exhaust chamber behind the hut, and is directly ventilated outside through the chimney. Therefore, it is preferable because it does not leak indoor moisture.

By providing a damper and a flow rate sensor in the exhaust chamber, it is possible to suppress excessive ventilation in the middle of winter and strong winds. In addition, by providing a fan and an airflow sensor in the exhaust chamber, it became possible to improve the shortage of ventilation during the mid-air-conditioning, summertime, and when there is no wind. Furthermore, by providing a damper, a fan, and a flow rate sensor in the exhaust chamber, the ventilation rate throughout the year can be automatically maintained in an optimum range or a range desired by the occupant.
