Rooftop Air Conditioning Unit Shell and Tube


Water - Cooled Heat Exchanger


U-tube dry evaporator. The structure of the U-tube dry evaporator is shown in Figure 8-18, which consists


of a number of tubes with different bending radii, and the open ends of the U-shaped tubes are connected


to the same tube sheet. In addition to the straight tube type, the shell, the baffle plate and the refrigerant


and the refrigerant flow is the same way. After the refrigerant liquid throttling into the lower part of the end


of the light, after two processes of heat absorption from the top of the export, it is commonly used in small


freon refrigeration device. The advantage is that the thermal expansion coefficient of different materials


will not produce internal stress, and U-shaped tube bundle can be more convenient to pull out to clean.


Dry evaporator because the liquid filling capacity compared with the full liquid type reduced by 80% to


85%, so it does not exist the impact of static pressure of refrigerant liquid, there is no oil discharge


difficulties, cold refrigerant frozen and frozen pipe Agent surface difficult to control the same problem, but


also has a compact structure, high heat transfer coefficient.


Straight tube type dry evaporator. Its structure and full-liquid evaporator similar, the difference is in a


number of horizontal smooth copper tube with a number of blocks on the reverse arrangement of the cut


arc of the circular baffle area, the more important is the work process is completely different. In a dry


evaporator, the liquid of the refrigerant evaporates in the tube while the liquid refrigerant (water or brine)


is cooled outside the tube.
