Provided is an air conditioning device specialized for heating, wherein when a trial operation is performed in an inverse cycle of a heating cycle, a drain water from an indoor heat exchanger can be prevented from overflowing from a drain pan. The air conditioning device is comprised of a compressor (21); an indoor heat exchanger (42); an outdoor heat exchanger (23); an outdoor expansion valve (24) provided between one end of the indoor heat exchanger (42) and one end of the outdoor heat exchanger (23); a four-way switching valve (22) which switches from a first state that the discharge side of the compressor (21) is connected to the other end of the indoor heat exchanger (42) and the intake side of the compressor (21) is connected to the other end of the outdoor heat exchanger (23) to a second state that the discharge side of the compressor (21) is connected to the other end of the outdoor heat exchanger (23) and the intake side of the compressor (21) is connected to the other end of the indoor heat exchanger (42), or vice versa; an indoor fan (43) which blows air to the indoor heat exchanger (42); and a control portion which controls at least the compressor (21), the outdoor expansion valve (24), the four-way switching valve (22), and the indoor fan (43). The control portion switches the four-way switching valve (22) to the second state in a trial operation mode. In the trial operation mode, a drain water control period in which a drain water suppression control is performed so that the control portion operates the compressor (21) and stops the indoor fan (43), is provided. |
