ースを経て排出される。Then, since the compressor (2) is operated to start the cooling or heating operation and the blower (9) is operated at the same time, the outside air in the ceiling space is sucked from one of the ventilation holes (15a) and the radiation fins are discharged. After cooling (17), it descends as indicated by the dashed arrow in FIG. 3, and then rises along the front and rear surfaces of the movable plate (21), bypassing the lower end (33) of the partition plate (18). In this case, the electric component (8) is cooled and then discharged from the other ventilation port (15b) to the outside of the unit body (1) via the blower (9). As described above, since the power transistor (4) and the other electric components (8) are forcibly cooled by the outside air, there is no possibility that the temperature will rise to an abnormal temperature, and the water-cooled heat exchanger (3) is provided with an evaporator. During the heating operation, the drain water condensed on the refrigerant pipe (25) and the service valves (26a) (26b) temporarily accumulates on the bottom plate (11). Since it was started from 11), there is no danger of drain water entering the electrical box (10).
1) The drain water above is discharged from the drain port (29) to the outside via a drain hose.
