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. |
