Open Cooling Tower Structure, Fill Material & Heat Dissipation Mechanism
Open cooling tower: circulating water sprays on fill material, contacts with air directly, part of water evaporates and takes away latent heat. Main parts: water distribution pipe, spray nozzle, PVC fill, drift eliminator, fan, water basin, overflow and drain valve. Heat dissipation relies mainly on water evaporation; wet bulb temperature determines the lowest achievable cooling water temperature. Open tower water will lose by evaporation and drift; continuous water replenishment and blowdown are required to control water hardness. Xiteliduo counter flow open cooling tower is widely matched with large cold storage water cooled rack in inland industrial park. Drift eliminator function: trap fine water droplets, reduce water carry loss and reduce surrounding salt/scale splash pollution. PVC fill is easy to aging under long time high temperature and sunlight; broken fill disturbs water distribution and reduces efficiency. Open tower is exposed to atmosphere; dust, leaves, algae and bacteria easily enter water basin, accelerate pipeline fouling. Water blowdown ratio setting: balance dissolved solid concentration, avoid rapid scaling while control water waste. Refrigeration maintenance & repair company checks water conductivity, fill integrity and nozzle blockage regularly.
