    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： An air-conditioning apparatus includes a body casing of an indoor unit formed in a substantially rectangular parallelepiped shape. The body casing is formed with a body inlet port on a body bottom, and a body outlet port is formed in each body side. The body casing houses a centrifugal fan, a fan motor rotatably driving the centrifugal fan, and an indoor heat exchanger disposed so as to surround an outer periphery of the centrifugal fan in planar view. In each of the body outlet port, a joint is protrudingly provided with a body-side duct connecting portion that connects a duct thereto. Further, outlet ports are formed. The air-conditioning apparatus includes a plurality of outlet units each protrudingly provided with an outlet-side duct connecting portion that connects the duct thereto. Furthermore, at least one of the joints is formed with a plurality of the body-side duct connecting portions.

    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≧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≦j≦N−1) component of the non-azeotropic refrigerant.
