部（図示せず）が設けられている。FIG. 2 is a schematic configuration diagram of an indoor unit during a dry operation, showing one embodiment of the present invention. In the figure, A is an indoor unit, 1 is an indoor blower, 2 is an indoor heat exchanger, 3 is a pipe through which a refrigerant flows, and 4 is a throttle mechanism. During the dry operation, the indoor heat exchanger is separated into a condenser and an evaporator via a throttle mechanism. Further, the indoor unit is provided with an operation control unit having a microcomputer in which various operation control functions are programmed, and a detection unit (not shown) for detecting humidity, temperature, and the like.

6）。When a dry operation instruction is issued by a remote controller or forced operation, the air conditioner starts operating. At the same time, the room temperature is detected (Step 301), and if the room temperature is equal to or higher than the set temperature range (Step 302), the operating frequency of the compressor is controlled based on the room temperature, and the outdoor fan is continuously operated to perform cooling. A slightly dry operation is possible, and a dehumidification operation is performed while lowering the room temperature (steps 307 and 308).
Also, when the room temperature enters a certain set temperature range by the room temperature detection (step 301) (step 302), the operation shifts to the control of the operating frequency of the compressor based on the relative humidity, and the room temperature is lowered by appropriately controlling the outdoor fan speed. Intermediate dry operation in which dehumidification operation is performed (steps 303 and 30)
Four). Further, when the room temperature is lower than a certain set temperature range (step 302), the operation time of the outdoor fan is shortened as much as possible, so that the heating-like dry operation can be performed. 305,30
