Evaporator
An evaporator is used in an air-conditioning system to allow a compressed cooling chemical to evaporate from liquid to gas while absorbing heat in the process. It can also be used to remove water or other liquids from mixtures.
There are two types of evap.:

Forced Convection Type uses a fan or pump to force the liquid being cooled over the evap.
Natural Convection Type has the liquid being cooled flows naturally to the evap. due to the density differences of the chilled and warm liquid.
There are three types of evap.
1.Bare-Tube
