Abstract

To suppress decline of recirculation efficiency of conditioned air while placing a boundary girder along the boundary between an air conditioning machine chamber and an air-conditioned chamber.SOLUTION: A framework structure includes an air-conditioned chamber 20, an air conditioning machine chamber 40 which is next to the air-conditioned chamber 20 and in which an air conditioning machine 42 that supplies conditioned air to the air-conditioned chamber 20 is installed, a ceiling slab 30 across the air-conditioned chamber 20 and the air-conditioning machine chamber 40, and a boundary girder 52, which is provided along the boundary between the air-conditioned chamber 20 and the air-conditioning machine chamber 40 and below and separated from the ceiling slab 30, and forms a reflux channel 54 in the space below the surface of the ceiling slab 30 that circulates the conditioned air from the air-conditioned chamber 20 to the air-conditioning machine chamber 40.SELECTED DRAWING: Figure 2

Claims
