    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.

    摘要： A heat source unit and refrigerant used in an existing refrigeration system are replaced with new refrigerant and a new heat source unit which employs the new refrigerant and is equipped with an oil separator and extraneous-matter trapping device. An indoor unit of the existing refrigeration system may be used, in its present form, or replaced with a new indoor unit. Further, connecting pipes used for the existing refrigeration are reused. After replacement of refrigerant, the refrigeration system performs an ordinary operation after having performed a cleaning operation. The extraneous-matter trapping device is provided in a refrigerant pipe close to the heat source unit or in a bypass channel connected to the refrigerant pipe close to the heat source unit. Alternatively, only the heat source unit of the existing refrigeration system is replaced with a new one, and there is employed refrigeration oil which has no mutual solubility with respect to HFC or has very low mutual solubility.

    摘要： An air conditioner has a refrigeration circuit formed by sequentially connecting a compressor 1, a condenser 2, an electronic expansion valve 4 and an evaporator 7 by pipes (6, 10). A compressor bypass pipe 12 is provided to connect an outlet of the evaporator 7 with an inlet of the condenser 2. A first on-off valve 11 is located in the bypass pipe 12. The air conditioner is controlled to switch to either a forced circulation operation or a natural circulation operation. In the forced circulation operation, the first on-off valve 11 is closed, the expansion valve 4 is opened to a first degree to allow refrigerant to pass therethrough, and the compressor 1 is operated in a running state. In the natural circulation operation, the first on-off valve 11 is opened, the expansion valve 4 is opened to a second degree, different from the first degree, to allow refrigerant to pass therethrough, and the compressor 1 is stopped.
