What are the types of cooling towers?

How do I choose a cooling tower? With most applications, determining and understanding the minimum size a cooling tower should be is crucial. For most wet cooling towers, the ideal size can be understood by a combination of four metrics. These are heat load, approach, range, and wet bulb temperature.

Is cooling tower effective? Cooling tower effectiveness (in percentage) is the ratio of range, to 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).

What are the types of cooling towers? The types of cooling towers based on the air flow generation are Natural draft, Mechanical draft, Cross-flow and Counter-flow towers. Natural Draft cooling towers use the design and shape of the tower itself to move up the air naturally using fans. ... Mechanical Draft towers tend to use a fan to force the air.

What is TR capacity in cooling towers? Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). A ton is the amount of heat removed by an air conditioning system that would melt 1 ton

What should be the TDS of cooling tower? The TDS concentration of cooling tower water and the pH values depend on its original sources and on the cycle number of circulations inside the building. The TDS values change from 300 to 1,200 ppm.

How do cooling towers reduce water temperature? The decrease in the outlet water temperature by using water path cooling is proved by the conventional heat transfer formulae. The second method deals with the decrease the liquid to gas flow ratio(L/G) by increasing the air velocity with the help of cylinder blocks near the louvers of cooling tower.

What causes high pH in cooling tower? The circulating water is aerated each time it passes over the cooling tower. This reduces the carbon dioxide concentration in the water to the equilibrium value for the atmospheric conditions, causing the pH to rise. The rapid increase in pH across the tower can lead to calcium carbonate scaling on the tower fill.

What is the temperature of cooling tower water? As previously stated, typical HVAC conditions call for an entering water temperature of approximately 95ºF (35.0ºC). All PERFECT Cooling Towers are capable of withstanding temperatures of at least 120ºF (48.9ºC) with standard fill materials..

What is the percentage of evaporation loss in cooling tower? As air rises inside the tower, it receives the latent heat of vaporization from the water, and thus the water is cooled. As a rule of thumb, for every 10°F (5.5°C) of water cooling, 1% total mass of water is lost due to evaporation.
