Witryna15.4.1 General. In air-cooled condensers, condenser heat is rejected directly to the ambient air. Thus, the condensing temperature is a function of the ambient air dry-bulb temperature. The obvious advantage of air-cooled condensers relative to water-cooled condensers is that cooling water is not needed. Consequently, air-cooled … WitrynaAIR 41.
