摘要： The present invention provides a gas discharge device for discharging non-condensable gas in a refrigeration and air conditioning system, and a method thereof. The gas discharge device comprises an evaporative condenser, which isolates liquid refrigerant and non-condensable gas by condensing a gas mixture of gaseous refrigerant and non-condensable gas exiting the refrigeration and air conditioning system, and leads the isolated liquid refrigerant into the refrigeration and air conditioning system, but discharges the isolated non-condensable gas. The method comprises an evaporative condensation process, a gas discharge process and a liquid discharge process. The present invention can prevent the accumulation of non-condensable gas in a condenser of a refrigeration and air conditioning system, and thereby helps to guarantee the refrigerating capacity and energy efficiency of the refrigeration and air conditioning system, such that it operates safely and efficiently.

摘要： A falling film evaporator (100), a housing (101) thereof being accommodated with a heat exchange tube (304), a perforated plate (205) and a spraying tube (202), the perforated plate (205) being provided between the spraying tube (202) and the heat exchange tube (304), such that refrigerant sprayed from the spraying tube (202) is sprayed onto the surface of the heat exchange tube (304) by means of distribution of the perforated plate (205); spraying openings (301) on the spraying tube (202) have a strip shape, and the extension direction of the openings is perpendicular to the length direction of the spraying tube (202). By means of configuring the length direction of the spraying tube (202) to be substantially perpendicular to the length direction of the heat exchange tube (304), refrigerant sprayed from the spraying openings (301) flows substantially in the length direction of the housing (101), the flow path of the refrigerant being lengthened, avoiding uneven spraying on the surface of the heat exchange tube (304).

摘要： A condenser (100), comprising a shell (112), an inlet pipe (120), and an anti-impact plate (204). The shell (112) has an accommodating cavity (202). The inlet pipe (120) is a circular pipe having a gradually increasing inner diameter from the inlet to the outlet. The inlet pipe (120) is arranged to pass through the upper end of the shell (112), the outlet of the inlet pipe (120) being accommodated in the accommodating cavity (202). The anti-impact plate (204) is accommodated in the accommodating cavity (202), and the anti-impact plate (204) is positioned below the outlet of the inlet pipe (120). There is a gap between the anti-impact plate (204) and the outlet through which fluid flowing from the outlet can flow. The condenser (100) can reduce the friction loss and local resistance of the refrigerant gas flowing into the inlet pipe (120), such that the dynamic pressure of the refrigerant gas entering the condenser (100) is partially converted into static pressure, and reduce the static pressure loss of the refrigerant gas entering the cylinder from the inlet, thereby increasing the condensing pressure of the refrigerant gas in the condenser (100) to enhance the heat exchange performance.
