Claim 9:
10. The air-conditioning apparatus of claim 9, wherein
the controller sets an initial control target value of the injection refrigerant pressure-reducing device in the simultaneous heating and defrosting operation mode at a point of time immediately after an operation mode is switched from a heating operation mode to the simultaneous heating and defrosting operation mode, and
when the injection refrigerant pressure-reducing device is in a fully closed state immediately before the operation mode is switched, the initial control target value of the injection refrigerant pressure-reducing device is set to a value corresponding to a fully opened state or a predetermined opening degree of the injection refrigerant pressure-reducing device, and when the injection refrigerant pressure-reducing device is not in the fully closed state immediately before the operation mode is switched, the initial control target value of the injection refrigerant pressure-reducing device is kept at a value corresponding to an opening degree of the injection refrigerant pressure-reducing device in the heating operation.
