| Abstract: | This paper describes part of the detailed methodology for the thermal design of wet, counterflow and crossflow types of mechanical and natural draught cooling towers. Starting with a brief introduction, an attempt is made here to present different steps of cooling tower design. The steps include: selection of a cooling tower; determination of tower characteristic ratio; computation of moist air properties; determination of the ratio of the water-to-air loading; integration procedure for the tower characteristic ratio. The design of a cooling tower needs the use of different logical decisions, empirical relations and assumptions. The choice of a proper tower and its proper design would increase its efficiency and help conserve energy. |
