An evaporator is a device used to turn (or allow to turn) the liquid form of some chemical into its gaseous form. For example, an evaporator is used in an air conditioning system to allow the compressed cooling chemical (for example, Freon) to evaporate from liquid to gas, absorbing heat in the process.
