Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning system in which an air duct is integrated with a structural frame. The ceiling height is secured.

[0002]

2. Description of the Related Art In order to satisfy diagonal restrictions and sunshine restrictions,
There are so-called low-rise buildings with a low height per floor. In a building with low floor height, the space between the slab and the ceiling (ceiling pocket) can be kept to a minimum, so when installing equipment members that intersect the beams in the ceiling pocket, a lower ceiling with a lower ceiling is required. It will be constructed. FIG. 6 is a side view of an air passage according to a conventional air conditioning system. On the lower surface side of the slab, girders 2 and girders 4 are projected, and girder 2 has a larger sectional area than girder 4 and floor 6
It projects to the side. Air conditioning machine room 8 in a corner of the same floor
And an air conditioner 10 is installed in the air conditioning machine room 8. A base end of a supply duct 12 is connected to the air conditioner 10, and the supply duct 12 penetrates through the partition 14 and is arranged in the ceiling pocket on the office floor side. The supply duct 12 installed in the ceiling pocket on the office floor side
The girders 2 and the girders 4 are arranged so as to intersect with each other, and particularly, the supply duct 12 at the intersection with the girder 2 is covered with a descending ceiling 18 provided lower than the ceiling 16. Further, also on the lower surfaces of the ceiling 16 and the beam 4, in order to secure a gap for disposing the branch duct 12a,
The ceiling 16 was constructed in a state in which it was slightly lowered from the lower surface of the beam 4 compared to the normal ceiling position.

[0003]

However, if the ceiling height is lowered or the descending ceiling 18 is provided for the construction of the supply duct 12, the ceiling surface will not be unified and will be unnatural, and the living environment will be reduced. Will be reduced.
On the other hand, if the ceiling pocket is made large in order to secure the ceiling height or eliminate the descending ceiling 18, the floor height becomes large and the diagonal line restriction and solar radiation restriction cannot be satisfied, and the desired number of floors and total floor area cannot be obtained. It became a building. The present invention has been made in view of the above circumstances, it is possible to secure an air-conditioning air passage without taking a large ceiling pocket, and as a result, provide an air-conditioning system that can secure a large ceiling height while having a low floor height. The purpose is to enable a comfortable living space while ensuring the desired number of floors and total floor area.

[0004]

In order to achieve the above object, the structure of the air-conditioning system in which the air passage according to the present invention is integrated with the structural frame is the same as the beam projecting downward from the upper slab of the room to be air-conditioned. The main supply duct from the air conditioner installed on the same floor as the room to be air conditioned passes through the upper slab and the body duct is installed on the upper floor of the room to be air conditioned in a direction orthogonal to this beam. It is characterized in that it is connected to a duct, the branch duct is arranged between the beams in the same direction as the beam and within the height of the beam, and the branch duct penetrates the slab and is connected to the frame duct. is there.

[0005]

[Operation] The main supply duct is inserted through the upper slab to the upper floor and connected to the body duct, and the branch duct connected to the body duct is arranged between the beams of the air-conditioned room, Beams and ducts no longer intersect. This eliminates the need to provide a gap for arranging the duct between the beam and the ceiling, enables the ceiling to be installed close to the lower surface of the beam, and increases the ceiling height despite the low floor height.
