In a system using a high side float, what occurs if the float sinks?

In a system using a high side float, if the float sinks, it indicates that the liquid refrigerant level in the float chamber has dropped, leading to inadequate refrigerant supply to the evaporator. This situation results in the evaporator starved of refrigerant, causing it to operate under insufficient flow conditions.

When the evaporator does not receive enough refrigerant, it cannot absorb sufficient heat from the surrounding area, which can lead to a drop in the cooling capacity and potentially prevent the refrigerant from fully vaporizing. This can cause issues like reduced efficiency and even potential damage to components over time, as the refrigerant may not effectively transport heat, leading to operational problems.

Understanding the operation of the float mechanism is crucial in maintaining proper refrigerant levels in these systems, ensuring that the evaporator remains properly supplied for effective cooling.
