Abstract :

The fill medium in the cooling tower which provides the surface for heat transfer,isa key factor in the performance of cooling tower.Currently used fill is made from PVC corrugated sheets with passages for air. It suffers from the limitations of scaling and more resistance to the flow of air. The range of cooling tower is 6 to 12°Cand approach of the order of 5 to 6°C. If we achieve a greater range and closure approach to wbt, the operating cost on pumping water can be considerably reduced. The reduction in resistance to air flow will save the operating cost on fan. This work is an attempt to develop the cooling tower with more porous nature of fill and without using any type of draught. The fill medium is a stretched nylon net in zigzag pattern arranged vertically in numbers. The trials conducted on cooling tower without draught gives the range of 6°C and approach of 11°C for hot water temperature of 35°C. Thus the nylon net arranged in zigzag pattern can be used as the fill medium for cooling tower with better performance. Proper combination of size of zigzag net, density of fill and height of fill has to be worked out.
