What is the outcome of unraveling the insulation on a thermal bulb attached to a discussion pipe in a refrigeration system?

When the insulation on a thermal bulb attached to a discussion pipe in a refrigeration system is unraveled, the thermal bulb can no longer accurately measure the temperature of the refrigerant. This disruption in its function can lead to improper signals being sent to the compressor regarding the cooling load.

As a result, the compressor may fail to operate effectively, leading to a scenario known as a "flooded evaporator." In this condition, the evaporator coil does not completely vaporize the refrigerant, causing liquid refrigerant to accumulate and flood the coil. This can severely impact the overall efficiency of the refrigeration system and can result in potential damage to the compressor if liquid refrigerant returns to it.

The other outcomes related to increased compressor efficiency, cooler suction line temperatures, or compressed refrigerant leakage are less likely to occur directly as a result of unraveling the insulation on the thermal bulb.
