Claim 5:
6. The air-conditioning apparatus of claim 5, wherein
in the simultaneous heating and defrosting operation mode, the controller controls the associated outdoor fan for the parallel outdoor heat exchanger that is the defrosting target such that a control amount of the associated outdoor fan reaches a normal-time control target value set based on the outside air temperature, and
the normal-time control target value of the associated outdoor fan for the parallel outdoor heat exchanger that is the defrosting target is a target value that is required to cause the outdoor fan to be stopped or the rotation speed of the outdoor fan to be reduced to the minimum value, when the outside air temperature is less than or equal to the predetermined value in the simultaneous heating and defrosting operation mode, and that is required to cause the rotational speed of the outdoor fan to be increased to a rotational speed of the outdoor fan during a heating operation that is performed before the operation mode is switched from the heating operation mode to the simultaneous heating and defrosting operation mode, or to be increased to the maximum value, when the outside air temperature is higher than the predetermined value in the simultaneous heating and defrosting operation mode.
