Claim 4:
5. The air-conditioning apparatus of claim 4, wherein
the air-conditioning load state detection unit is an outside-air temperature detection unit configured to detect an outside air temperature, and
based on a detection value obtained by detection that is performed by the outside-air temperature detection unit immediately before the operation mode is switched from a heating operation mode to the simultaneous heating and defrosting operation mode, the controller controls in the simultaneous heating and defrosting operation mode, a control amount of one of the plurality of outdoor fans that is associated with one of the parallel outdoor heat exchangers that is a defrosting target, such that when an outside air temperature is less than a predetermined value, the associated outdoor fan is stopped or a rotation speed of the associated outdoor fan is reduced to a minimum value, and when the outside air temperature is higher than the predetermined value, a current value is maintained or the rotation speed of the associated outdoor fan is increased to a maximum value.
