The working principle of the evaporator is to use the evaporation method to heat the solution and vaporize and remove some of the solvent to improve the solution concentration. The evaporator is the cooling output equipment in the refrigerator. The refrigerant evaporates in the evaporator and absorbs the heat of the low-temperature heat source medium to achieve the purpose of refrigeration. The types of evaporators include: full liquid evaporator, dry evaporator, circulating evaporator and spray evaporator. The evaporator is mainly composed of a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation of the liquid, and promotes the boiling and vaporization of the liquid. After vaporization, the liquid reaches the evaporation chamber in a large space. These liquids can be separated from the steam by their own condensation or the role of the demister.
