Evaporative Condensers :
In systems involving heat transfer, evaporative condenser is a device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. In so doing, the latent heat is given up by the substance and transferred to the surrounding environment. Condensers can be made according to numerous designs, and come in many sizes ranging from rather small (hand-held) to very large (industrial-scale units used in plant processes).
For example, a refrigerator uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. Evaporative Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants and other heat-exchange systems. Use of cooling water or surrounding air as the coolant is common in many condensers.
- The heat exchanger section wraps around the sides of the unit with the compressor inside.
- Evaporative condensers can be used inside or outside of a building and under typical conditions, operate at a low condensing temperature.
- Typically these are used in large commercial air-conditioning units.
