Venturi Cooling Tower

Description: An innovative cooling tower based on the principle of venturi is developed by Cooling Concept. The process industries have already adopted the venturi effect for several gas-liquid systems like scrubbers, absorption towers and aeration with better results. Being a gas (air) & liquid (water) system, the cooling tower also requires the creation of air current for its effective mixing with water and with a large contact heat-mass transfer area. Here, venturi plays a very vital role and because of its design effectiveness, the cooling tower performs better, with almost a negligible power cost and an enhanced temperature drop with lower approach. In the venturi cooling tower, a large quantity of air is induced into the tower by cooling jets as it is injected through spray nozzles at the top of the vertical venturi plenum. No fans are utilised in this design. The effective mixing of air and water in the plenum permits evaporative heat transfer to take place without the use of any packing material. The cooling water collected in the sump is pumped back to the cooing water circuit for return cycle. The venturi cooling tower has the benefits of both fan type and natural draught type of cooling towers. Unlike the fan type, venturi tower performs without fans and fills. Therefore, it does not have associated operating and maintenance cost.
