What effect would a float filled with liquid have on a system using a high side float?

In a refrigeration system using a high side float, the primary function of the float is to control the flow of refrigerant entering the evaporator. If the float is filled with liquid, it indicates that there is an excess of refrigerant in the system, effectively causing the high side float to close or restrict the flow of refrigerant to the evaporator. This situation leads to a condition where insufficient refrigerant reaches the evaporator, resulting in it starving for refrigerant.

The concept of “starving” refers to the state where the evaporator does not receive an adequate amount of refrigerant necessary for proper cooling. This can lead to reduced efficiency, potential ice formation on the evaporator coils, and ultimately poor system performance. The float mechanism is designed to prevent flooding in the evaporator by managing the refrigerant flow based on its liquid level; therefore, a high liquid level in the float indicates a need to limit or stop the flow to maintain balance in the system.
