Condenser coils usually consist of arrays of copper tubes that penetrate at right angles closely stacked aluminium plates. These plates provide a system of continous fins for enhancing air-side heat transfer.Even though air cooled condenser coils can be cooled by natural convection, they are usually installed with fans.
An evaporator is a device used to turn the liquid form of a chemical into its gaseous form. The liquid is evaporated, or vaporized, into a gas. It can also be used to remove water or other liquids from mixtures. The process of evaporation is widely used to concentrate foods and chemicals as well as salvage solvents. One of the most important applications of evaporation is in the food and beverage industry. Foods or beverages that need to last for a considerable amount of time or need to have certain consistency, like coffee, go through an evaporation step during processing
