2. Description of the Related Art Ventilation of a parking building having a plurality of parking floors divided into upper and lower compartments has conventionally been performed by installing an intake fan and an exhaust fan on each parking floor and using a ventilation device including the intake fan and the exhaust fan. It is held individually for each parking floor.

[0003]

Therefore, the higher the parking building is, the larger the number of intake fans and exhaust fans becomes, and the space for installing the intake fans and exhaust fans is secured for each parking floor. This is costly and requires more space for the ventilator to be used throughout the parking building. Furthermore, in buildings that exceed a prescribed floor area, the fire prevention law requires that the fire prevention section be set to a prescribed size, and even in the case of parking buildings, the floor must be covered by walls within the fire prevention section (3000 square meters) on each parking floor. It will be necessary to partition into multiple parking lots, but if you try to ventilate by such a conventional method in such a parking building, you will have to install an intake fan and an exhaust fan for each parking lot on each parking floor, which is even more so. is there.

The degree is enough.

The present invention has been devised in view of the above circumstances, and an object of the present invention is to reduce the cost and the space for installing a ventilation device to effectively use the space in a parking building. It is advantageous to achieve the above, and particularly to provide a method of ventilating a parking building suitable for a parking building in which only a car enters and leaves by an unmanned transfer device.

[0005]

In order to achieve the above object, the present invention provides a ventilation from a lowermost parking floor to an uppermost parking floor when ventilating a parking building having a plurality of parking floors divided vertically. An air passage is formed in the building body so that a continuous air flow from the end to the end of each floor is possible, and a fire damper that can be opened and closed is arranged in the air passage,
At the lowermost parking floor, an intake fan is attached to a building frame location facing the upstream end of the air flow to suck outside air into the parking floor, and at the uppermost parking floor at the downstream end of the air flow. An exhaust fan is attached to the building frame facing to exhaust the air inside the parking floor to the outside of the parking building, and the intake air and the exhaust fan suck and exhaust the outside air to the lowermost position along the air flow. It is characterized in that it is made to flow from the floor to the uppermost parking floor.

Further, according to the present invention, the parking floor has a plurality of parking lots partitioned by walls, and the wall has a continuous air flow passing from one end of each parking lot to the other. A sub air passage is formed in the sub air passage, and a fire protection damper is provided in the sub air passage so as to be openable and closable. Further, the present invention is characterized in that the intake fan and the exhaust fan are driven when the temperature of the parking floor exceeds a predetermined value.

[0007]

[Operation] An air flow is created in the parking building by driving the intake fan and the exhaust fan, and the outside air flows from the lowermost parking floor to the uppermost parking floor by the air flow, thereby ventilating the parking building. It
