MERKELS METHOD FOR DESIGNING INDUCED DRAFT COOLING TOWER

In general, cooling towers are used todissipate process waste heat into the atmosphere. In this paper, induced draftcooling tower has been designed by simplified merkel’s method. The design ofcooling tower is based on Merkel’s method. The tower characteristic isdetermined by the ratio of range and log-mean-enthalpy difference. Optimizationof the operating conditions for cooling tower applications in cooling water isextremely significant in order to get the most energy efficient operating pointfor these systems. A simple algebraic formula is used to calculate the optimumwater-to-air flow rate. Merkel’s method is the most widely accepted theory forcooling tower calculations. It combines equations for heat and water vaportransfer. The objective of this paper is to present the design procedure ofcounter ? flow cooling towers in a simplified manner
