    摘要： A refrigeration apparatus has a refrigerant. The refrigerant is a non-azeotropic refrigerant mixture containing 50% by weight or more and 80% by weight or less of a high-boiling point refrigerant, 10% by weight or more and less than 50% by weight of a medium-boiling point refrigerant having a boiling point lower than that of the high-boiling point refrigerant, and 20% by weight or less of a low-boiling point refrigerant having a boiling point lower than that of the medium-boiling point refrigerant. The content of the high-boiling point refrigerant is larger than that of the medium-boiling point refrigerant, and the content of the medium-boiling point refrigerant is larger than that of the low-boiling point refrigerant. Piping through which the refrigerant derived from the compressor and flowing into the condenser passes includes a countercurrent flow configurator in which the refrigerant flowing through the piping is countercurrent to the cooling air.

    摘要： A single-stage refrigerating system includes a compressor, a condenser, an evaporator, and a heat exchanger for exchanging heat between a refrigerant in a path from the evaporator to the compressor and a refrigerant in another path from the condenser to the evaporator, and a non-azeotropic refrigerant mixture used in the system. The refrigerant mixture is a combination of a refrigerant having a normal boiling point of approximately room temperature and a low-boiling-point refrigerant having a normal boiling point below −60° C. A dew point of the refrigerant mixture at a pressure in the condensing process after the compression is above room temperature. The boiling point is higher than the dew point at a pressure in the lower-pressure region in a path from the evaporator to the compressor. The combination may include butane or isobutane as the high-boiling-point refrigerant component having a normal boiling point of approximately room temperature and having a low evaporating pressure and ethane or ethylene as the low-boiling-point refrigerant component suitable for achieving ultra-low temperature.

    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.
