摘要： In order to modify the composition of a non-azeotropic mixed refrigerant circulating through the refrigeration cycle of a refrigerating and air-conditioning apparatus using a refrigerant rectifier column, the level of the liquid refrigerant rich in the low-boiling point fraction that is obtained from a refrigerant rectifier column (11) and which collects in a refrigerant container (14), as well as the level of the liquid refrigerant rich in the high-boiling point fraction that collects in an accumulator (6) are adjusted so as to modify the composition of the refrigerant circulating through the refrigeration cycle. The circuit structure can be made simple, and the energy need not be supplied during the cooling and heating operations to modify the composition of the non-azeotropic mixed refrigerant.

摘要： In the detection of circulating compositions in the cycle of a non-azeotropic refrigerant composed of three or more kinds of refrigerants, there have been drawbacks in that the number of sensors required is large, and large errors are contained in the circulating composition which can be detected. To overcome these drawbacks, the refrigerating and air-conditioning apparatus comprises at least a compressor, a condenser, a pressure reducing device, and an evaporator, and in a refrigerant cycle which uses as a working refrigerant a non-azeotropic refrigerant composed of N kinds (N.gtoreq.3) of refrigerants and is provided with composition detecting means for detecting the circulating compositions of the non-azeotropic refrigerant, circulating compositions are determined by using (N-2) relations on compositions among a first component to a j-th (2.ltoreq.j.ltoreq.N-1) component of the non-azeotropic refrigerant.

摘要： An air-conditioning apparatus has different two modes including a response detection diagnosis in which a control unit diagnoses a trouble of a component device during the trouble diagnosis operation based on presence or absence of a response from the operational state sensor when the mode has forcibly changed the device operation, and a performance detection diagnosis in which a trouble is detected by a detection value of the operational state sensor at a time when the operational state of the trouble diagnosis operation is stable, and the performance detection diagnosis is executed after the response detection diagnosis is executed.
