If the high side float were to fill with liquid and sink, what would be the result?

When the high side float fills with liquid refrigerant and sinks, it indicates that the float valve is not functioning properly. As a result, this malfunction can lead to an improper balance of refrigerant flow within the system. Specifically, when the float sinks, it can restrict or shut off the flow of refrigerant to the evaporator.

In refrigeration systems, the evaporator is responsible for absorbing heat from the environment and allowing the refrigerant to evaporate. If the evaporator is starved of refrigerant, it doesn't receive enough refrigerant to absorb heat efficiently. Consequently, this leads to reduced cooling capacity and overall inefficiency in the system.

Understanding the components and flow in a refrigerant system is crucial. The proper operation of the high side float is essential for managing the refrigerant flow and maintaining system efficiency. If this valve fails and allows the evaporator to starve, the system can experience inadequate cooling and increased operational problems.
