AIR CONDITIONING DEVICE

摘要

An air conditioning device capable of removing even frost deposited on a device and a member which are located downstream of airflow which exchanges heat with an outdoor heat exchanger.  In an air conditioning device (1), in heating operation, a refrigerant circulates through a compressor (21), a four-way switching valve (22), an indoor heat exchanger (41), an expansion valve (24), and an outdoor heat exchanger (23), in that order.  In defrosting operation, a control section (11) performs defrosting-operation control for stopping an outdoor fan (26) and causing the four-way switching valve (22) to allow the refrigerant discharged from the compressor (21) to flow to the outdoor heat exchanger (23), and when a predetermined condition is established, the control section (11) performs fan-defrosting-operation control for allowing the outdoor fan (26) to rotate for a predetermined time period after the completion of the defrosting operation.
