In the flooded shell-and-tube evaporator, the low-pressure liquid-vapor refrigerant mixture enters the manifold, installed along the entire bottom of the evaporator.
Small openings along the manifold provide uniform spray of refrigerant over the tubes inside the shell and tube evaporator, where the refrigerant absorbs heat from the relatively hotter water flowing through the tubes. This heat transfer causes the refrigerant to evaporate on the pipe surfaces. The resulting steam passes through an eliminator on its way back to the compressor suction. The eliminator prevents liquid from being sucked into the compressor along with the refrigerant vapor.
The now chilled water can be used in many applications such as process and comfort.
