Abstract
A falling film evaporator includes a plurality of evaporator tubes through which a volume of thermal energy transfer medium is flowed, a separator to separate a flow of liquid refrigerant from a vapor and liquid refrigerant mixture, and a distributor operably connected to the separator to distribute a flow of liquid refrigerant over the plurality of evaporator tubes. The distributor includes a distributor inlet to receive the flow of liquid refrigerant from the separator, a sparge channel connected to the distributor inlet to flow the liquid refrigerant therethrough and exiting the sparge channel via a plurality of sparge openings in an upper surface of the sparge channel, and a distribution sheet disposed below the sparge channel through which the liquid refrigerant flows onto the plurality of evaporator tubes. A flow rate of liquid refrigerant through each sparge opening of the plurality of sparge openings is substantially equal.
