Shell and Tube Falling Film Evaporator

A falling film evaporator, also referred to as a spray evaporator, is a type of heat exchanger that is quite comparable to a flooded evaporator, yet distinctly different. Refrigerant is sprayed from the top of falling film heat exchanger on to its tubes, resulting in the formation of a thin layer of refrigerant liquid film that covers the tubes. This thin film lowers the hydrostatic pressure during boiling and evaporating, which leads to an increase in the evaporator's heat exchange efficiency. In fact, its efficiency can be enhanced by up to 5 % more than that of a flooded evaporator.

Refrigerant steam doesn't require any additional heating, allowing the evaporative temperature to elevate significantly. Compared with a flooded evaporator, the falling film evaporator boasting a 30% higher heat transfer coefficient and an astonishing 35% reduction in refrigerant charge. This evaporator is designed to work with a wide range of compressors, including screw, centrifugal, and magnetic bearing models. This liquid dispensing defoaming device has achieved the national patent,. Specifications Shell & Tube Falling Film Evaporator, Standard Type
