In an automatically operated, flooded shell-and-tube cooler, what is the primary function of an electric float switch?

In an automatically operated, flooded shell-and-tube cooler, the electric float switch plays a critical role in maintaining the proper level of refrigerant within the shell. Its primary function is to monitor the refrigerant level and ensure that it remains within optimal operational limits. When the refrigerant level drops below a certain point, the float switch activates, controlling the flow of refrigerant into the shell to prevent potential operational issues such as compressor damage or inadequate cooling performance.

Maintaining the appropriate refrigerant level is essential for the efficient operation of the cooling system, as insufficient refrigerant can lead to overheating and reduced cooling effectiveness. Therefore, the electric float switch is vital in regulating the flow of refrigerant and ensuring the system operates safely and efficiently.
