Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Thermal processes and apparatus (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 6:
7. The air-conditioning apparatus of claim 5, further comprising:
a high-pressure sensor that detects a pressure of the refrigerant flowing between the refrigerant-refrigerant heat exchanger and the first expansion device;
a second liquid temperature sensor that detects a temperature of the refrigerant flowing between the refrigerant-refrigerant heat exchanger and the first expansion device;
a two-phase temperature sensor that detects a temperature of the refrigerant flowing between the bypass expansion device and the refrigerant-refrigerant heat exchanger; and
a low-pressure sensor that detects a pressure of the refrigerant flowing between the second flow switching device and the compressor,
wherein the controller senses a refrigerant composition, based on the pressure detected by the high-pressure sensor, the temperature detected by the second liquid temperature sensor, the temperature detected by the two-phase temperature sensor, and the pressure detected by the low-pressure sensor.
