Document Type and Number:
WIPO Patent Application WO2006044448
Kind Code:
A3
Abstract:
A falling film evaporator is provided for use in a two-phase refrigeration system or process system. The evaporator (80, 280) includes a shell (100) having an upper portion (102), a lower portion (104), and a tube bundle (106) having tubes extending substantially horizontally in the shell (100). A hood (112) is disposed over the tube bundle (106), the hood (112) having an upper end (114) adjacent the upper portion (102) above the tube bundle (106), the upper end (114) having opposed substantially parallel walls (116) extending toward the lower portion (104), the walls terminating at an open end (118) opposite the upper end (114). Once liquid refrigerant (120) or liquid refrigerant (120) and vapor refrigerant is deposited onto the tube bundle (106), the substantially parallel walls (116) of the hood (112) substantially prevent cross flow of refrigerant vapor or liquid and vapor between the tubes of the tube bundle (106).
