Final answer:
Too much Superheat can result in the evaporator being starved, as it causes the refrigerant vapor to be too hot, reducing the cooling efficiency and potentially damaging the compressor.
Step-by-step explanation:
Increasing the Superheat too much may starve the evaporator. In refrigeration and air conditioning systems, the term 'superheat' refers to the number of degrees a vapor is above its saturation temperature (boiling point) at a particular pressure. Too much superheat indicates that the refrigerant vapor is too hot, and this over-heating can cause insufficient refrigerant to evaporate in the evaporator coil. Without adequate refrigerant, the evaporator cannot absorb enough heat, leading to inefficiencies in the cooling process and potential damage to the compressor from the ingestion of superheated vapor.
