What is the primary function of the evaporator in a refrigeration system?

The primary function of the evaporator in a refrigeration system is to absorb heat. In this process, the refrigerant enters the evaporator at a low temperature and pressure. As it passes through the evaporator coils, it absorbs heat from the surrounding environment or the space that needs to be cooled. This absorption of heat causes the refrigerant to evaporate, transforming from a liquid phase into a vapor phase. This phase change is crucial, as it is what allows the refrigeration cycle to effectively remove heat from the area being cooled, thereby maintaining the desired temperature.

Understanding the evaporator's role is essential in commercial refrigeration, as it directly influences the system's efficiency and effectiveness in maintaining cool temperatures.
