Abstract:
Cooling towers are evaporative heat transfer devices in which atmospheric air cools warm
water with direct contact between the air and the water by evaporating cooling of water. The
main objective of this study is to analysis the cooling tower performance, comparing the
performance of natural and induced draft cooling tower and finding out the effect of adding
toner to circulating cooling fluids. This was done by establishing and modifying experimental
set up constructing computer program and varying the quality of circulating fluids by adding
together at different ratio. Natural and induced draft cooling tower and computer program gives
us the various data required for calculation. From the result obtained a comparative study on
terms of tower characteristics (kav/L), water to air flow ratio (L/G), efficiency, range,
percentage of make-up water and evaporation heat loss are presented in graphical form. The
graph showed that the performance of cooling tower is affected by the type of cooling tower
and the quality of circulating fluids. The graphical analysis shows the cooling tower
characteristics and efficiency decrease with an increase in (L/G) the induced draft cooling
tower shows better performance than natural draft cooling tower. The result also shows that
with the adding of toner with water cooling tower performance increase and as tower
percentage increases the tower performance also increase.
