WebAdvantages and disadvantages of Dry Type and Flooded Type evaporators. The Flooded Type evaporator draws water in the tube and the refrigerant evaporates outside the tube cluster, so the heat transfer surface is substantially in contact with the liquid refrigerant. Generally, the amount of refrigerant charged in the casing is about 55% to 65% ...
