The throttling device has a throttling working mode for cooling and a defrosting working mode not used for cooling. The throttling working mode and the defrosting working mode are switched with each other. The condenser has a first heat release mode corresponding to the throttling working mode and a second heat release mode corresponding to the defrosting working mode, and a heat release amount of a refrigerant flowing through the condenser in the second heat release mode is lower than a heat release amount of the refrigerant flowing through the condenser in the first heat release mode.

摘要： A method for producing capillaries from nonferrous alloys, in particular of Al, which includes the continuous cold rotary extrusion of a blank having a solid cross-section, obtained by casting, in order to produce a tube having a hollow cross-section. The deformation of the blank to be extruded is achieved only by using friction force. The method further includes at least one step of cold drawing of the extruded tube in order to reduce its diameter to the diameters corresponding to a capillary.

摘要： A heat exchanger, a heat pump system, and a heat exchange method. The heat exchanger operates in a cooling mode or a heating mode. A heat exchange medium flows through via a first flow path within the heat exchanger in the cooling mode, and flows through via a second flow path within the heat exchanger in the heating mode. A diversion component is disposed within the heat exchanger. The diversion component is configured such that the length of the first flow path is different from the length of the second flow path; moreover, a partial segment of the first flow path and a partial segment of the second flow path overlap with each other, and flow directions of the heat exchange medium therein are identical.
