As you study refrigeration keep in mind that every component’s function is listed or described in its name. For example an evaporator is called an evaporator because that is where the refrigerant evaporates or turns from a liquid to a vapor. A condenser is where the refrigerant condenses or changes from a vapor back into a liquid.
