Falling film evaporator having an improved two-phase distribution system

摘要

An improved two-phase refrigerant distributor for use in a falling film evaporator in a refrigeration chiller system defines apertures in its undersurface from which serrated collars depend. The serrations cooperate to define locations below the undersurface of the distributor to which liquid refrigerant is drawn prior to exiting the distributor. As a result, the hang-up and/or travel of liquid refrigerant on the distributor undersurface is reduced or eliminated.
