What would happen if the insulation was removed from the bulb of an expansion valve?

Removing the insulation from the bulb of an expansion valve would result in a flooded evaporator. The bulb is used to sense the temperature and pressure of the refrigerant in order to regulate the flow through the expansion valve. When the insulation is removed, the bulb can access external temperatures rather than just the temperature of the refrigerant. This can falsely signal that the refrigerant is too cold, potentially leading to an overfeeding condition where too much refrigerant enters the evaporator. This excessive flow can overwhelm the evaporator's capacity, resulting in liquid refrigerant accumulating in it, which is identified as a flooded evaporator. In this scenario, the evaporator cannot adequately convert refrigerant into vapor, leading to inefficient refrigeration cycles and possible compressor damage from liquid slugging.
