An evaporator is a device used in a process to turn the liquid form of a chemical substance such as water into its gaseous form vapor. The liquid is evaporated, or vaporized, into a gas form of the targeted substance in that process. One kind of evaporator is a kind of radiator coil used in a closed compressor driven circulation of a liquid coolant. That is called an airconditioning system A/C or refrigeration system allowing a compressed cooling chemical, such as R22 coolant or R410A, to evaporate/vaporize from liquid to gas within the system while absorbing heat from the enclosed cooled area for example, a refrigerator or indoor room in the process. This works in the closed A/C or refrigeration system with a condenser radiator coil that exchanges the heat from the coolant into the ambient environment. A heat exchanger condenser coil is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in heating and refrigeration. An example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant. Features.
