However, in the case of conventional ventilation equipment, in order to ventilate a plurality of floors 101 to be ventilated, a plurality of induction blowers 104 and floor main exhaust fans 102 and floor main exhaust fans 102 are provided on each floor 101 to be ventilated. A machine room to be installed must be provided for each floor to be ventilated, and the facility cost and the operating cost of the entire equipment increase, and there is a problem in terms of space in each floor 101 to be ventilated due to the installation of the machine room was there.
In addition, the main exhaust fan 102 for each floor is not provided, but a large exhaust fan 102 ′ for ventilating the air A in the entire ventilation target floor 101 through a duct or the like connected to each ventilation target floor 101 is provided. The problem of space in each ventilation target floor 101 due to the installation of the machine room for providing the main exhaust fan 102 for each floor is solved, but a huge amount for exhausting the air A in the entire ventilation target floor 101. The operating cost was a big problem.
In view of this situation, the main problem of the present invention is to effectively solve the above problems with a rational improvement.

The first characteristic configuration of the present invention is:
In a ventilation facility using an inductive blower consisting of a wind guide cylinder and a fan that blows air into the cylinder in a state where the space between the cylinder is open to the periphery,
The attraction-type air blower is disposed in a vertical space in a sinusoidal space extending over a plurality of floors of the building, the cylinder is positioned above the fan, and the plurality of floors of the building are located in an attraction area between the fans and the cylinder. one or more upper side of the ventilation target floors faces of, and ventilation different one or more of the lower side of the ventilation target floor of the upper layer side of the multi-storey the building to the suction area below said fan It exists in the point arranged in the state where the target floor faces.

In other words, in the attraction area between the fan and the cylinder disposed in the sinus space, the air discharged from the fan attracts and discharges the air in the upper floor of the ventilation target floor and discharges in the suction area below the fan. Because the air in the floor of the floor to be ventilated on the lower layer side is sucked and discharged by the suction force of the floor, each floor main exhaust fan for discharging the air in the floor from each floor to be ventilated like the conventional ventilation equipment There is no need to provide the floor, so that the equipment cost and the operation cost of the ventilation equipment as a whole can be reduced, and the ventilation equipment can be made favorable in terms of energy saving. Since the machine room for installing the main exhaust fan on each floor is not required, it is advantageous in terms of space saving of the ventilation facility on the ventilation target floor, and the effective use area on the ventilation target floor can be expanded.
In addition, in the conventional equipment having a large exhaust fan for exhausting the air in the floor subject to all ventilation, the exhaust fan is large in order to suck and exhaust the air in the floor subject to all ventilation. This requires operating power, and thus the operating cost of the exhaust fan increases enormously, but air is released into the cylinder while the space between the cylinder for guiding air and the cylinder is open to the surroundings. In the case of equipment of this configuration using an attraction-type blower composed of a blow-in fan, the floor air of the floor to be ventilated facing the attraction area between the fan and the cylinder is attracted by the discharge air from the fan and discharged. Since it is discharged through the cylinder together with air, the exhaust air volume can be increased as a whole without increasing the operating power of the fan (in other words, the amount of air sucked and discharged by the fan) compared to conventional equipment. it can.
In other words, since the air in the floor to be ventilated facing the attraction area is attracted by the air discharged from the fan and is discharged through the cylinder together with the air discharged, the same amount as the exhaust air volume as a whole in conventional equipment In order to secure the amount of exhaust air, the amount of air sucked and discharged by the fan can be reduced by the amount of the induced air, so that the operating power of the fan can be reduced as compared with the conventional equipment.
In short, with this configuration, it is possible to obtain a ventilation facility that is superior in terms of exhaust efficiency and energy saving compared to conventional facilities, and the operating cost of the entire ventilation facility can be greatly reduced.

The second feature configuration of the present invention is a preferred configuration in the implementation of the first feature configuration.

The point is that they are arranged in parallel in a focused manner in a state of being arranged in parallel corresponding to the arrangement.

  In other words, with this configuration, the shape of the parallel arrangement of the attraction-type blower is appropriately selected according to the shape of the sinus space (particularly, the shape in plan view), and the sinus space is effectively used to the maximum. In this state, it is possible to efficiently arrange a plurality of attracting blowers, and to ensure a large exhaust capacity while effectively achieving space saving. The air in the floor can be discharged more efficiently.

The third characteristic configuration of the present invention is a preferable configuration in the implementation of the second characteristic configuration.
A partition member is provided at a position on the air inlet side in the parallel arrangement group of the cylinders so as to suppress mutual interference between the air blowing paths to the cylinders and located between the air blowing paths to the cylinders. In the point.

  In other words, with this configuration, the air flow blown from the fan to the cylinder in each of the attracting blowers arranged in parallel is blown into each cylinder without mutual interference by the partition member, so no partition member is provided. Compared to the configuration, the air flow from the fan to the cylinder can be maintained in a rectified spiral shape with good induction efficiency, so that the air in the upper floor of the ventilation target floor facing the induction area of the induction blower It can be attracted and discharged efficiently.

The fourth feature configuration of the present invention is a preferred configuration in the implementation of any one of the first to third feature configurations.
The sinusoidal space is a space that also serves as a piping space for vertical pipes extending over a plurality of floors of the building.

  In other words, with this configuration, the sinusoidal space can also be used as the piping space for the vertical pipes to further reduce the space for ventilation equipment in the building and to increase the effective use area of each ventilation target floor as a whole. Can do.

The fifth feature configuration of the present invention is a preferred configuration in the implementation of any one of the first to fourth feature configurations.
An auxiliary air blower for assisting the movement of air in the floor to the attraction area or the suction area facing the ventilation target floor is provided on the ventilation target floor.

  In other words, with this configuration, even if the floor to be ventilated is not structured so that the floor air flows linearly from the air supply side to the exhaust side, the auxiliary air blower is installed in the floor air of the floor to be ventilated. Is guided to the attracting area or the suction area where the floor to be ventilated faces to form a desired flow of air in the floor, so that the floor to be ventilated can be efficiently ventilated.

The sixth feature configuration of the present invention is a preferred configuration in the implementation of any one of the first to fifth feature configurations.
The entrance side runway that leads the vehicle to the floor to be ventilated as a parking lot is provided in a tower-like or tunnel-like runway space,
The vehicle entrance from the entrance side travel path is arranged on the side opposite to the sinusoidal space on the ventilation target floor as a parking lot.

Is arranged on the opposite side, so that the air flow from the entrance to the induction area or the suction area facing the floor to be ventilated from the vehicle entrance from the entrance side runway that is the air supply source forms the ventilation as a parking lot. The target floor can be effectively ventilated.
Then, when the vehicle travels on the entrance-side travel path to the floor to be ventilated as a parking lot, a conveyance effect is obtained in which the vehicle pushes the space air in the travel-path space of the entrance-side travel path, and thereby the floor to be ventilated. Since air is efficiently supplied through the travel path space, it is possible to promote exhaust by the attractive blower and increase the ventilation efficiency. In addition, this makes it possible to reduce or eliminate the need for large air supply fans arranged on the floors to be ventilated, even when air supply fans for ventilation have been required. Since the machine room for installing the air supply fan is not required, the facility cost and the overall operation cost of the ventilation facility can be reduced, and it can be made a good ventilation facility in terms of energy saving. It is also advantageous in terms of space saving of the ventilation facility in, so that the effective use area on the floor subject to ventilation can be further expanded.

In other words, with this configuration, the exhaust air from the separate ventilation system facility is discharged to the entrance-side travel path between the vehicle entrance and the entrance that is the supply source of the ventilation target floor as a parking lot, Since the exhaust from another ventilation system facility can be supplied to the ventilation target floor as a parking lot through the entrance side runway, there is no need to provide an air supply fan on the ventilation target floor as a parking lot. Since the machine room for installing the air fan is not required, it is possible to save space and reduce the equipment cost of the air supply fan. In addition, the entire building including the separate ventilation system facility can be ventilated smoothly. Therefore, the operation cost required for ventilation can be reduced and the energy saving can be improved.
In addition, even when there is no traveling vehicle on the entrance-side travel path and the effect of transporting the space air in the travel path space by the vehicle cannot be expected, an attraction area or suction that faces the ventilation target floor as a parking lot from another ventilation system facility A flow of air flowing to the area can be formed, and in addition to the effect of transporting the spatial air by the vehicle, the floor to be ventilated as a parking lot can be ventilated very smoothly.
