えられる。Through these 77 rotations and 270 rotations, outdoor air is sucked in through the suction ports 10 and 34 of the back plate 3 and the left side panel 33, and is discharged from the outlet grille 32. At this time, when the rotation speed of the compressor 150 increases and the vibration of the compressor 15 becomes large, this vibration is transmitted through the bottom plate 2 to the left side panel 33, which has weakened rigidity, and the back plate 3, and is fixed only in a few places by screws. This is likely to be transmitted to the partition plate 4 that is not connected. However, since the left side panel 33, back plate 3, and partition plate 4 are made of vibration-damping steel plates, the above-mentioned vibrations can be suppressed to a low level.

とができる。(G) Effects of the Invention As described above, the present invention provides a partition plate that partitions the interior of the housing into a machine room and a heat exchange room, and an exterior that is provided with a suction port, among the plates constituting the housing of a heat exchange unit. Since the panel is made of distributed steel plates, even if the vibrations generated by the operation of the compressor and blower inside the housing are transmitted to the less rigid partition plates and exterior panels, these vibrations can be suppressed to a low level and noise can be kept low. .
