What is the primary function of the fluid in the flooded system of a shell and tube chiller?

The primary function of the fluid in the flooded system of a shell and tube chiller is to flow through the tubes. In this system, the refrigerant is used to absorb heat from the water or other fluid passing through the tubes. The design of a flooded chiller allows the tubes to be filled with the refrigerant, maximizing surface area for heat transfer. As the fluid flows through the tubes, it picks up heat from the refrigerant, which is crucial for the cooling process. This efficient heat exchange is essential for the overall operation of the chiller, ensuring it effectively removes heat from the environment it is meant to cool.
