摘要： A heating, ventilation and air conditioning (HVAC) system includes a condenser (18) flowing a flow of refrigerant therethrough, and a falling film evaporator (12) in flow communication with the condenser. The falling film evaporator includes a plurality of evaporator tubes (38) through which a volume of thermal energy transfer medium is flowed and a distributor (42) to distribute a flow of liquid refrigerant over the plurality of evaporator tubes. The distributor includes a distributor box (46) and a distribution sheet (48) positioned at a bottom surface of the distributor box having a plurality of ports (56) therein to distribute the flow of liquid refrigerant downwardly over the plurality of evaporator tubes. A plurality of baffles (56) is positioned at the distribution sheet to divide the distributor box into a plurality of compartments to ensure a homogeneous flow of the liquid refrigerant is delivered through the plurality of ports.

摘要： A liquid distributor delivers a falling flow of the liquid to be distributed substantially uniformly along a longitudinal extent of the liquid distributor. The liquid distributor has a bottom wall including a longitudinally extending distribution plate having a plurality of laterally spaced and longitudinally extending channels. A shell and tube evaporator for chilling a working fluid incorporates the liquid distributor as a distributor of liquid onto the heat exchange tubes of a tube bundle disposed within an interior volume of the shell. Each channel is aligned with a respective column of the plurality of vertical columns of heat exchange tubes and is configured to deliver a falling flow of liquid refrigerant onto the respective tube column substantially uniformly along the longitudinal extent of the respective tube column.

摘要： A heating, ventilation and air conditioning (HVAC) system includes a condenser to condense a flow of refrigerant into a liquid state. The system further includes an economizer assembly having at least one separator chamber to separate liquid refrigerant from vapor refrigerant. The economizer assembly shares an upper common wall with at least a portion of the condenser and the flow of refrigerant from the condenser into the economizer assembly proceeds through a flow opening in the upper common wall. A falling film evaporator exchanges thermal energy between the liquid refrigerant and a medium flowed through a plurality of evaporator tubes in the evaporator.
