Description

INDUSTRIAL APPLICABILITY The present invention is arranged in the ceiling of a building in order to blow out conditioned air supplied from an air conditioner to an air conditioning target space in an air conditioning facility of a building, or to suck air in the air conditioning target space and discharge it to the outside. Related to the air control box.

As a conventional air control box, a box made of steel plate is generally provided with a heat insulating material such as glass wool, or a box having a heat insulating box made of a glass wool board having an aluminum foil attached to the surface thereof. and so on. For example, as shown in FIG. 9, there is a conventional air control box 100 in which a reinforcing frame 101 made of an iron plate is provided outside a heat insulating box body 102 made of glass wool board.

On the other hand, as a prior art related to the present invention, for example, there is a "air-conditioning outlet muffler box" described in Patent Document 1. This "air-conditioning outlet muffler box" has a structure in which a single rib frame having a predetermined shape is incorporated inside a glass wool assembly box.

As shown in FIG. 10, in the air restraint box 100 arranged in the space above the ceiling 103, the reinforcement frame 101 is exposed to the space 103 behind the ceiling, so that the air restraint during the cooling operation in summer. Due to the temperature and humidity difference between the conditioned air (cold air) flowing in the box 100 and the space 103 above the ceiling, dew condensation occurs on the surface of the reinforcing frame 101, and the dew condensation water increases with the passage of time. In some cases, it may be dropped on the ceiling board 104 and the ceiling board 104 may deteriorate.

In addition, the dew condensation water is transmitted to the opening 104a of the ceiling board 104 through the opening 105a of the gas outlet 105 of the air restraint box 100, and the water enters the ceiling board 104 from the inner peripheral end surface of the opening 104a. As a result, the area around the opening 104a may be soiled.
