Performance and Optimisation of Cooling Tower by Employing Nylon Net as Fill Material

Cooling water or processed water is the need of any industry. It requires cooling water. Cooling water is one of the major constituent of industry’s annual electricity bills. This situation raise the need for research in techniques employed for functioning of cooling tower. Our project entitled Optimisation and Performance of Cooling Tower by Employing Nylon Net as Fill Material is undertaken as a part of development and improvement of cooling tower. This paper presents how the energy consumption of evaporative cooling tower can be reduced without affecting the performance of cooling tower. This type of cooling tower utilizes the principle of direct evaporative cooling. The position of inlet hot water nozzle results in increase heat transfer rate due to more time circulation of water. For increasing the travelling length of circulation of water, we used different types of patterns of nylon net such as zig-zag pattern, full length zig-zag pattern and vertical parallel pattern. This type of direct spray type evaporative cooling tower has an advantage of reduced maintenance because of elimination of matrix required for induced draft type cooling tower.
