Question

Write a detailed discussion about the fundamental concept of the working and function/roles of EVAPORATORS in refrigeration systems.

Please provide references if there is any.

Answer 1

An evaporator is used to change any liquid material into gas. In this process, heat is absorbed. The evaporator transfers heat from the refrigerated space into a heat pump through a liquid refrigerant, which boils in the evaporator at a low-pressure. In achieving heat transfer, the liquid refrigerant should be lower than the goods being cooled. After the transfer, liquid refrigerant is drawn by the compressor from the evaporator through a suction line. Liquid refrigerant will be in vapour form upon leaving the evaporator coil.
