What is the working principle of an evaporator?

[McIsla]

Evaporator works by utilizing the evaporation method, where a solution is heated to vaporize and remove part of the solvent, thereby increasing the concentration of the solution. The evaporator is the cooling output device in a refrigeration system. The refrigerant evaporates in the evaporator, absorbing heat from the low-temperature heat source medium to achieve the purpose of refrigeration. 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, the liquid reaches the larger space of the evaporation chamber, where it is separated from the vapor by its own condensation or the action of a demister.
