The low side float should be located between which two components?

The low side float is designed to manage the flow of refrigerant in low-pressure systems, particularly in applications such as commercial refrigeration where liquid refrigerants need to be leveled before they enter the compressor. The float’s role is to maintain a sufficient amount of refrigerant in the evaporator to ensure proper operation and to prevent the compressor from drawing in vapor or causing damage due to liquid slugging.

When positioned between the evaporator and compressor, the low side float serves to regulate the refrigerant flow coming out of the evaporator. This ensures that only vapor reaches the compressor, which is critical for efficient operation and long-term reliability of the system. The effectiveness of this component is closely tied to its placement, as it relies on the conditions present between these two key components to properly manage refrigerant levels and pressure.

Locating the float between the compressor and the expansion valve could lead to improper flow regulation and potential issues with refrigerant management. It is important for the float to accurately gauge the refrigerant levels as it exits the evaporator to ensure that the compressor operates with optimal performance, thereby maintaining system efficiency and preventing any operational issues.
