Experimental study on the hybrid closed circuit cooling tower (HCCCT) has been done having a rated capacity of 136 M Bare-type copper coil having an outer diameter of 15.88 mm has been used in the 1.14 m x 2.36 m x 3.2 m dimensional tower. Cooling capacity and pressure drop have been studied with respect to variable air inlet velocities, wet-bulb temperatures, cooling water inlet temperatures and air to cooling water volume flow rate ratio (G/W ratio). Performance characteristics from the experimental study were found to conform well to the rated ones. The results are supposed to serve as basic design parameter for the HCCCT. (C) 2008 Elsevier B.V.
