Another name for the evaporator used in cooling systems is the evaporator. Evaporator is also called cooling coil. Evaporator; It is the section in the cooling system where the refrigerant enters as a liquid and leaves as a gas after evaporation. When the refrigerant enters the channels of the evaporator, it absorbs the heat from the cooled substance or the environment, and while absorbing the heat from the environment, it starts to boil and evaporates. As a result of these processes, the evaporator performs the cooling event, which is the general purpose of the entire system.
