Claim 1:
2. The air-conditioning apparatus of claim 1, wherein
the controller sets initial control target values of the compressor, the pressure reducing device, and the defrosting refrigerant pressure-reducing device based on the air-conditioning load state and the operation state detected immediately before an operation mode is switched from a heating operation mode to the simultaneous heating and defrosting operation mode, and
at time of starting the simultaneous heating and defrosting operation mode, the controller controls the compressor, the pressure reducing device, and the defrosting refrigerant pressure-reducing device such that the control amounts of the compressor, the pressure reducing device, and the defrosting refrigerant pressure-reducing device reach the respective initial control target values.
