What is the function of an evaporator?

[McNoah]

Evaporator's function is to evaporate the low-pressure refrigerant coming from the expansion valve, absorbing the heat from the air inside the vehicle, thereby achieving the purpose of cooling the interior. The working principle of an evaporator is to use the evaporation method, where the solution is heated, causing part of the solvent to vaporize and be removed, thus increasing the concentration of the solution. Types of evaporators include: flooded evaporators, dry evaporators, circulating evaporators, and spray evaporators. The evaporator mainly consists of two parts: the heating chamber and the evaporation chamber. The heating chamber provides the heat required for evaporation, promoting the boiling and vaporization of the liquid. After vaporization, it reaches the larger space of the evaporation chamber, where the liquid is separated from the vapor by its own condensation or the action of a demister.
