Abstract (en)

[origin: EP2746699A1] A refrigeration cycle apparatus is obtained which allows high accurate estimation of the composition of a refrigerant even when the detection accuracy of a used sensor is the same as that in an existing one. If an error equivalent to that for a first inlet temperature sensor 12 is observed in an outlet temperature TO that is a temperature detected by a first outlet temperature sensor 13, a constant-temperature line in a superheated gas state is sufficiently inclined as compared to a constant-temperature line in a two-phase gas-liquid refrigerant, and an enthalpy error ´hTO caused with the error is sufficiently smaller than that in the case of a temperature sensor 103 in a related art example.
