    Abstract: 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.

    Abstract: A heating, ventilating, air conditioning, and refrigeration (HVAC&R) system (10) includes a falling film evaporator (38) configured to vaporize a low pressure refrigerant liquid into a low pressure refrigerant gas. The falling film evaporator (38) includes a shell (106), a lower tube bundle (102) and a upper tube bundle (104). The shell (106) includes a first tubesheet (240) disposed at a first end portion of the shell (106) and a second tubesheet (242) disposed at a second end portion of the shell (106). The lower tube bundle (102) is disposed within a bottom portion of the shell (106), and the upper tube bundle (104) is disposed above the lower tube bundle (102), each of the lower tube bundle (102) and the upper tube bundle (104) has ends respectively supported by the first and the second tubesheets (240, 242). An upper edge (136) of the upper tube bundle (104) extends above a horizontal midline of the shell (106) to enable the upper tube bundle (104) and the lower tube bundle (102) to distribute a force across a vertical extent of the first tubesheet (240) and the second tubesheet (242).
