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: To eliminate a fear of electrolytic corrosion even in the case where a heat exchanger to be connected to the outside of the plate-type heat exchanger has a copper piping, and to prevent any damage from being given to the brazed portions of the plate-type heat exchanger at the time of joining pipes and to prevent faults from being generated in joined portions. An intermediate pipe made of a material in which the value of polarization potential becomes lower than that generated between a body of the plate-type heat exchanger and the copper piping is interposed between the plate-type heat exchanger body and the copper piping. Further, the plate-type heat exchanger body is disposed in a position out of a vertical line of a joined portion between the copper piping and the intermediate pipe. Further, a joint constituted by an intermediate pipe and a copper pipe joined in advance through brazing or welding at a temperature higher than a temperature of brazing of the plate-type heat exchanger body is brazed at the same time of brazing of the plate-type heat exchanger body under the condition that the joint is arranged so that the intermediate pipe side of the joint is joined with the end plate of the heat exchanger body.

摘要: An air-conditioning apparatus is capable of suppressing refrigerant flow noise regardless the refrigerant state of an inlet of an expansion mechanism. In parallel to a flow control valve, an opening and closing valve that opens and closes a refrigerant passage and an expansion mechanism having porous bodies capable of passing a refrigerant therethrough are connected in series with each other. In a heating mode, in the case where a controller stops an operation of one or more of a plurality of indoor units and causes the other indoor unit(s) to operate, the flow control valve of the stopped indoor unit is fully closed and the opening and closing valve of the stopped indoor unit is opened.
