What is an evaporator
An evaporator is a type of heat exchanger wherein a liquid fluid, acting as a refrigerant, enters the tubes (fin tube coil). Due to the low pressure of the liquid, it absorbs heat from the fluid surrounding the tubes (such as air or water), causing it to boil, evaporate, and transition from liquid to gas, extracting heat from the environment and cooling it. This process earns the device its name. The performance of an evaporator depends on factors such as fluid type, heat transfer rate, pipe type, and temperature difference. Evaporators come in two primary types: shell and tube (water or water-cooled) and fin tube (air or air-cooled), both widely used in industrial applications. Typically, evaporator construction follows three designs:
1- Shell and tube type (blue or water cooled)
2-Fin tube (air or air cooled)
3-plate type
