Abstract: A refrigeration cycle apparatus includes a compressor, a first heat exchanger, a second heat exchanger, a third heat exchanger, a flow path switching valve, a first expansion valve, a second expansion valve, a third expansion valve, a refrigerant container, a first check valve, and a second check valve. The flow path switching valve switches a circulation direction of a non-azeotropic refrigerant mixture between a first circulation direction and a second circulation direction. A first port of the third expansion valve communicates with the refrigerant container through the third heat exchanger. A second port of the third expansion valve communicates through the first check valve with a first flow path between the first heat exchanger and the first expansion valve, and communicates through the second check valve with a second flow path between the second heat exchanger and the second expansion valve.

Abstract: An air-conditioning apparatus includes a refrigerant circuit including: a compressor; a high-pressure pipe for high-pressure refrigerant discharged from the compressor; a low-pressure pipe for low-pressure refrigerant to be sucked into the compressor; a first flow switching valve; an indoor heat exchanger; an expansion valve, a first outdoor heat exchanger; a second outdoor heat exchanger; and a second flow switching valve. The second flow switching valve switches flow passages for refrigerant flowing to the first outdoor heat exchanger and the second outdoor heat exchanger. The second flow switching valve includes a first chamber, a second chamber, and a slide valve that is moved by a differential pressure between the first and second chambers. At least one of the first and second chambers is connected with the high-pressure pipe or the low-pressure pipe.

Abstract: A refrigeration cycle apparatus, in which demand control is performed to adjust electric power, includes: a compressor, a driving rotation speed; a recording device that records, as data, a relationship between the driving rotation speed of the compressor and a temperature difference between a set temperature and a detected temperature, the set temperature being set as desired as a temperature control target for a temperature adjustment target, and the detected temperature being detected by a temperature detecting device disposed at a position at which a temperature of the temperature adjustment target is detected; and a main controller that, in response to a request for the demand control, calculates the temperature difference between the set temperature and the detected temperature, retrieves, from the recording device, data of the driving rotation speed of the compressor corresponding to the calculated temperature difference, and controls the compressor based on the retrieved driving rotation speed.
