Abstract
Provided is an air conditioning apparatus that is capable of suppressing increases in volume and cost of the apparatus and performing more suitable overheating protection. An electric compressor is an inverter-integrated electric compressor () integrally including a compressor (), an electric motor () that drives the compressor (), and an inverter () including a temperature sensor () that detects the temperature in the vicinity of a semiconductor switching device, wherein a controller () estimates a discharge temperature of the compressor () on the basis of a correlation of respective pressure loading characteristics for the detected temperature of the inverter (), for the rotational speed of the compressor (), and for the motive force of the compressor () in a refrigerating cycle ().
