The primary objective of a low side float in a refrigeration system is to prevent flooding of the evaporator. Flooding occurs when excessive liquid refrigerant enters the evaporator, which can impair heat exchange efficiency and lead to compressor damage. The low side float serves as a level control device that regulates the amount of liquid refrigerant that enters the evaporator. By maintaining the correct liquid level, the float ensures that only the necessary amount of refrigerant is present for optimal vaporization and heat transfer, preventing both flooding and ensuring effective operation of the system.

In contrast, maintaining low pressure, controlling refrigerant flow, and optimizing energy use are important aspects of refrigeration systems but are not the primary function of a low side float. These functions are typically managed through other components and controls within the system, highlighting the specialized role that a low side float plays in maintaining operational integrity and efficiency.
