How can we increase the efficiency of a cooling tower?
How to Increase Your Industrial Cooling Tower Efficiency
- Save energy.
- Reduce the amount of water being consumed.
- Decrease the amount of chemicals required for water treatment.
- Extend the equipment service life.
- Reduce operating costs, overall.
What are the factors affecting cooling of cooling tower?
Cooling tower performance depends on four factors (1) Range; (2) Heat load; (3) Ambient wet-bulb temperature or relative humidity and (4) Approach. Range is the temperature difference between the hot water inlet and cold water outlet at the tower.
Why are cooling towers more efficient?
“The important part of the heat transfer is the air movement through the fill media,” he said. “If you can increase your airflow through the media it really very directly impacts the heat transfer. So, the more air, the more cooling, the more cooling, the more efficient.
Which is a better indicator for cooling tower performance?
ii) “Approach” is the difference between the cooling tower outlet cold water temperature and ambient wet bulb temperature. Though both parameters should be monitored, the ‘Approach’ is a better indicator of cooling tower performance.
What causes low pH in cooling tower?
Stronger acids have lower pH values. Imbalances in cooling tower pH occur because the water is not pure — it is composed of more than just oxygen and hydrogen. Most process water contains significant concentrations of dissolved minerals, which tend to change the pH of the tower water, often significantly.
In which season cooling tower is more efficient?
It is the ratio between the range and the ideal range, i.e. difference between cooling water inlet temperature and ambient wet bulb temperature, or in other words it is =Range / (Range + Approach). The efficiency of the cooling tower is high in winter season as comparison to summer season.
Which has maximum effect on cooling tower performance?
Explanation: Natural Draft is where air circulates naturally without any external force, and the atmospheric draft is a type of natural draft. So, the mechanical draft is the type of cooling tower which gives the maximum heat transfer due to usage of fans for the circulation.
How to increase the efficiency of a cooling tower?
Therefore, water saving strategies could be considered as essential steps towards increasing cooling tower efficiency.
What is coolcooling tower?
Cooling tower essentially takes the hot/warm water from your heat exchanger/DG/Chiller etc and uses natural evaporation to cool it back down. Now Weather plays an important role as humidity of the environment (aka surrounding weather) directly affects the cooling efficiency of your Cooling tower.
What is cooling tower water chemistry and why is it important?
Closely monitoring cooling tower water chemistry can also help reduce deposition and corrosion, improving system efficiency and extending the service life of your equipment. Properly pretreating the cooling tower makeup water can help with this as well.
How does wet-bulb temperature affect cooling tower efficiency?
As can be seen from the above equation, the efficiency of the cooling tower is negatively correlated with the wet-bulb temperature of its ambient. Since the wet-bulb temperature raises with temperature, hotter climates enforce lower cooling tower efficiencies, which is compatible with intuition.
