    摘要: A refrigerating apparatus (81-91) using a non-azeotropic refrigerant is provided with a variable capacity compressor (1), a heat-source heat exchanger (5), a throttling device (4), a user-side heat exchanger (3), a variable capacity fan (7), a discharge pressure detector (16), a suction pressure detector (13), a refrigerant cyclic-composition detecting device (15). The detected cyclic composition is used to determine the state of the interior of the refrigerating apparatus; in addition in order to prevent malfunction of the apparatus, the refrigerating apparatus (81-91) is provided with detectors (24,28,35,36,37) to detect directly parameters which cannot be determined accurately owing to an error or the like in the detection of the refrigerant cyclic composition.
