<p>PROBLEM TO BE SOLVED: To provide an air conditioning device capable of executing a proper dehumidifying operation according to humidity load.SOLUTION: In an air conditioning device 1, a control portion 40 can execute a first dehumidifying operation and a second dehumidifying operation. The first dehumidifying operation is an operation to dehumidify an air-conditioned space by controlling an opening of an expansion valve 104 so that evaporation of a refrigerant is almost completed at a refrigerant outlet 138 of an indoor heat exchanger 13. The second dehumidifying operation is an operation to dehumidify an air-conditioned space by controlling the opening of the expansion valve 104 so that the evaporation is completed in a region closer to a refrigerant inlet 131 rather than the refrigerant outlet 138 of the indoor heat exchanger 13. The control portion 40 executes the first defrosting operation when the difference between the humidity of the air-conditioned space and a target humidity is out of a prescribed range, and executes the second dehumidifying operation when the difference between the humidity of the air-conditioned space and the target humidity is within the prescribed range.</p> |
