<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of removing even frost adhered to an apparatus and a member located at the downstream side of an air flow exchanging heat with an outdoor heat exchanger. <P>SOLUTION: In the air conditioner 1, a control part 11 performs defrosting operation control to stop an outdoor fan 26 and guide a refrigerant discharged from a compressor 21 toward the outdoor heat exchanger 23 by a four-way switching valve 22 during defrosting operation, and performs pressure equalizing operation control to stop the compressor 21 and operate the outdoor fan 26 after completion of the defrosting operation control. When a predetermined condition is satisfied, the control part 11 performs fan defrosting operation control to rotate the indoor fan 26 for a predetermined time while continuing operation to guide the refrigerant discharged from the compressor 21 toward the outdoor heat exchanger 23 after the completion of the defrosting operation, and during that time, operates the outdoor fan 26 at a rotational frequency lower than that during the pressure equalizing operation control. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
