摘要： A falling film evaporator is provided for use in a two-phase refrigeration system or process system. The evaporator includes a shell having an upper portion, a lower portion, and a tube bundle having tubes extending substantially horizontally in the shell. A hood is disposed over the tube bundle, the hood having an upper end adjacent the upper portion above the tube bundle, the upper end having opposed substantially parallel walls extending toward the lower portion, the walls terminating at an open end opposite the upper end. Once liquid refrigerant or liquid refrigerant and vapor refrigerant is deposited onto the tube bundle, the substantially parallel walls of the hood substantially prevent cross flow of refrigerant vapor or liquid and vapor between the tubes of the tube bundle.

摘要： An evaporator for use in a refrigeration system includes a shell and a tube bundle, the tube bundle having a plurality of tubes extending substantially horizontally in the shell. A hood is disposed over and laterally surrounds substantially all of the plurality of tubes of the tube bundle. A distributor is positioned between the hood and the tube bundle. The hood is asymmetrically disposed within the evaporator.
