An air-conditioning apparatus includes a time constant calculation means 20 that estimates a response time constant at a time when an opening degree of an expansion device 7 is changed on the basis of specifications of a compressor 3 that forms a refrigeration cycle of the air-conditioning apparatus, specifications of a load side heat exchanger 6, and an operating state quantity of the air-conditioning apparatus, a control constant calculation means 21 that calculates at least one of a control gain of the opening degree of the expansion device 7 and a control interval on the basis of a calculation result of the time constant calculation means 20, and a control constant change means 22 that changes a control constant. |
