Superheating in reefer system

• Super heating is the process of increasing the temperature above saturation temperature 
• Super heating is provided in low pressure side of the refrigeration cycle because liquid refrigerant should not go to the inlet of compressor.Liquid is incompressible if it reaches the compressor it damages the crank shaft.
• Super heating is doing in refrigeration by placing outlet line from the evaporator is placed adjecent to the outlet line form the condenser. So due to the high temperature in HP side compared to LP side, heat transfer is happening. Simply this act as a heat ex changer.
