What will happen if a low-side float is being used in a refrigeration system?

In a refrigeration system, a low-side float plays a critical role in maintaining the appropriate flow of refrigerant. It operates based on the level of liquid refrigerant present in the evaporator or the low-side of the system. When the liquid level drops below a certain point, the float mechanism activates to allow more refrigerant into the evaporator. This ensures that the evaporator is adequately filled, promoting optimal absorption of heat and preventing issues such as compressor cavitation.

This control of refrigerant flow is essential for maintaining the efficiency of the refrigeration cycle. While other components may be responsible for system shutoffs or pressure maintenance in the condenser, the primary function of the low-side float is to regulate the amount of refrigerant that circulates through the evaporator, thus directly influencing the system's performance.
