cooling Tower

Mixed Flow Series Principle of Operation:
1.the cooled water increases the temperature diferential between the water and the warm process fluid, which resultis in a reduced cosize, fewer coil connections, and reduced weights. this feature further reduces the tendency to fom scale on the coil since cooler wateroffers higher solubility for scale producing compounds.
2.parallel air and water paths minimize scale-producing dry spots that may be found on the bottom of tubes in conventional units.
3.the recirculating spray water falls from the coil to a wet deck surface section where it is cooled by a second fresh air stream using bothevaporative and sensible heat transfer processes.
4. water is pumped over the evaporative coil at a 6.5LS of coil face area to ensure continuous flooding of the primary heat transfersurface which enhances heat transfer efficiency and minimizes fouling and scale formation.
5. the coils section rejects heat through the fresh air evaporating, on the other side is through the sensible heat effect of pre-cooledcirculating spray water.reducing the coils evaporative cooling effect is helpful to reduce the possibility of the coils surface scaling.
