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

The primary function of an evaporator in a refrigeration system is to absorb heat. In this component, the refrigerant undergoes a phase change from a liquid to a gas. As it evaporates, it absorbs heat from the environment, which is essential for cooling purposes. This process allows the evaporator to extract heat from the area or substance being cooled, thereby lowering its temperature.

Understanding the evaporator's role is fundamental in the refrigeration cycle, as it is where the cooling effect occurs. The efficient absorption of heat during the evaporation process directly contributes to the overall effectiveness of the refrigeration system.
