When attempting to cool something down, there are four main methods that can be used to help with heat transfer. Radiation, evaporation convection, and conduction are the three methods. We are primarily concerned with the cooling effect of evaporation in cooling water treatment.Learn more by visiting Anytime Heating, Cooling and Plumbing
We’re all familiar with how evaporation cools in our daily lives. Our bodies use this mechanism to prevent us from overheating while we work up a sweat, and it’s the evaporation of sweat from our skin that actually eliminates heat, cooling our bodies down. An endothermic reaction is a cooling mechanism that requires evaporation.
A cooling water system is used to extract heat from processes or machinery by converting it to water in cooling tower water treatment. To allow the water to be reused, the heat absorbed by it must be dissipated. This happens in the cooling tower or evaporative condenser of an open, evaporative cooling water system.
A cooling tower is built to maximise air-water interaction and, as a result, allow some water to evaporate.
Only a small amount of the water evaporates, which cools the rest. In reality, evaporating only 2% of the water would result in a temperature drop of 9°C. When water is lost by evaporation in this manner, the remaining water’s mineral content becomes more concentrated. The less water the machine uses as fresh make-up, the higher the concentration factor).
This method of cooling by evaporation is relatively energy efficient and effectively conserves water by allowing hot water to be cooled and reused instead of being discarded. Significant problems may occur if water is not treated properly and is not maintained on a regular basis:
• The increase in water temperature increases the potential for corrosion and scale; • The retention of warm water in an open evaporative cooling water system increases the tendency for biological growth; • A cooling tower is in effect an air-washer a cooling tower is in effect an air-washer a cooling tower is in effect an air-washer a cooling tower is in effect an air-washer a cooling tower is in effect an air-washer a cooling tower is in effect an air-washer a cooling tower.
