R134A Water Cooled Screw Chiller With Falling Film Evaporator
Products Features About falling film evaporator
A falling film evaporator is also referred to a spray-type evaporator. During heat exchange, refrigerant is sprayed from the top of a heat exchanger to a heat exchange tube, and a thin layer of refrigerant film is formed only on the heat exchange tube, which refrigerant reduces static-level pressure and thus improves heat-transmission efficiency while the refrigerant is boiling.
