PROBLEM TO BE SOLVED: To provide an air conditioning device specialized for heating, preventing drain water of an indoor heat exchanger from overflowing from a drain pan when performing a trial operation in an inverse cycle to a heating cycle.SOLUTION: The air conditioning device includes: a compressor 21; the indoor heat exchanger 42; an outdoor heat exchanger 23; an outdoor expansion valve 24 provided between the indoor heat exchanger 42 and the outdoor heat exchanger 23; a four-way switching valve 22 switching between a first state of connecting the discharge side of the compressor 21 to the indoor heat exchanger 42 and connecting the intake side of the compressor 21 to the outdoor heat exchanger 23 and a second state of connecting the discharge side of the compressor 21 to the outdoor heat exchanger 23 and connecting the intake side of the compressor 21 to the indoor heat exchanger 42; an indoor fan 43 sending air to the indoor heat exchanger 42; and a control section switching the four-way switching valve 22 to the second state in a trial operation mode. In the trial operation mode, there is provided a drain water inhibition period in which drain water inhibition control is performed so that the control section operates the compressor 21 and stops the indoor fan 43. |
