As a water-cooled condensers, evaporative cooling of condensers first transfer of heat into the water, and then from the water outdoors. Evaporative condenser, however, combines the functions of a cooling tower and condenser are located in one package. Condenser water evaporates directly on the condenser tubes. Each pound of water evaporates thus removes about 1000 Btu refrigerant from flowing through the tube. As the water evaporates, mineral deposits left in the condenser and tend to accumulate. Thus, condenser water lost through evaporation, and some blown out in much the same way as what was done to the tower.
Capacitor discharge air containing water vapor, with its latent heat of vaporization is rejected outdoors, and a new air brought in to replace it. Evaporative condensers may be located under the direct access to the open air. They can also be in the room exhaust air is ducted to the outside of the building. Periodic cleaning of water deposits outside of condenser pipes is necessary to maintain the energy efficiency of the system.
Evaporative condensers are the least popular of the three types of condensation system. Their capacity ranges from 10 to 1000 tons.
In a comfort air conditioning system under normal design conditions, the temperature of the refrigerant in the condenser will be about 105F. Thus, the evaporative condenser offers the same energy saving benefits of a cooling system, as it does with water-cooled condenser.
Here's a simple, smaller than the evaporative condenser organization of the system, which is very popular, when less than 3 tons of cooling capacity. This, however, is not labeled, or often thought of as evaporation, condensation system. Many maintenance of air conditioning condensate from the evaporator is drained via a capacitor unit area. Condenser fan is designed to pick up and throw droplets of condensate water in the condenser coil, thus turning it into an evaporative condenser. This process disposes of condensation in a way that improves the device efficiency. Condensate water is really distilled water and, as a rule, leave very small Deposit on the condenser coil. If the condensate does not form on the evaporator, or when it is very lightweight device simply functions as an air-cooled system...
