付されている。DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. The ceiling 1 is provided with a suction port 21 for sucking room air in the room 9 into the space 20 above the ceiling at a position away from the case body 2. A suction port 22 is provided on a side wall of the case body 2. The suction port 22 is provided with a filter 23, and the heat exchanger 7 is provided behind the suction port 22 so as to face the filter. A blower 6 is installed in a space surrounded by the air guide plate 12 and the ceiling panel 8. The ceiling panel 8 attached to the lower part of the case main body 2 is provided with only the outlet 4. The other configuration is the same as that of the conventional one shown in FIG. 2, and corresponding members are denoted by the same reference numerals.

される。When the blower 6 is driven by the motor 5 during the operation of the air conditioner, the room air in the room 9 enters the space 20 above the ceiling from the suction port 21, and the suction port 22 and the filter 23 Is drawn into the case body 2 and passes through the heat exchanger 7 to be cooled or heated conditioned air. This conditioned air is guided by the baffle plate 12 and
And is urged, and is blown out of the outlet 4 into the chamber 9.

本体２をより小型化できる。Since the indoor air inlet 21 and the outlet 4 are separated from each other, a part of the conditioned air blown into the room 9 from the outlet 4 is entrained in the flow of the indoor air sucked into the inlet 21. The so-called short circuit phenomenon does not occur. Since the suction port 22 is provided on the side wall of the case main body 2, the suction space or the suction flow path in the case main body 2 is reduced, so that the size of the case main body 2 can be reduced. Furthermore, since the refraction of the air flow in the case body 2 is reduced, the flow resistance of the intake air is also reduced. There is also a large ceiling space
Since 20 is used as a flow path for the intake air, an air duct is not required, so that equipment and construction costs are reduced and flow resistance is reduced. Furthermore, if a plurality of suction ports 21 are installed at intervals, the air stagnation in the chamber 9 will be reduced, and the distribution of room temperature can be made uniform. In addition, the suction port 22 can be provided over the entire circumference of the case body 2, and in this case, the heat exchanger 7 can also be annular, so that the heat exchange area can be increased. If a centripetal fan is used instead of the illustrated centrifugal blower 6, the centrifugal fan can be installed in a space surrounded by the heat exchanger 7 and the baffle plate 12 can be omitted, so that the size of the case body 2 can be further reduced.
