The paper compares dry air-cooled condensers, water-cooled condensers with open and closed cooling towers, and evaporative condensers. Comparisons are made of operating condensing temperatures, compressor volume, power requirements, COP, cost, noise levels, and space occupied. For larger plants the evaporative condenser compares well with alternatives, its one major problem, as with other open water systems, is the risk of Legionaire's disease. Tests are reported on the use of ultraviolet light as a complete water treatment, showing it to be effective against most contaminants as well as Legionella. The main benefit of the evaporative condenser is the closeness of condensing temperature to the ambient wet bulb temperature resulting in appreciable power saving and obviating the need in many plants for condensing pressure control. An interesting design is shown for an induced water foam evaporative coolant, which eliminates the store of warmed water in most evaporative systems. D.W.H.
