General Information/Equipment Design
Evaporative condensers are used when the water supply is insufficient to operate a water cooled condenser, or when the condensing temperature is lower than air cooled condensers can achieve. A water/air mixture, the coolant, is sprayed into a chamber through which the hot vapor passes. As these substances come in contact with each other, the water quickly evaporates. The loss of this heat of vaporization causes the vapor feed to condense. This process requires much less cooling water than water cooled condensers, making evaporative condensers practical for hot, arid regions.
