Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat fromcooling water. The make-up water source is used to replenish water lost to evaporation. Hot water fromheat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units for further cooling.
Cooled water is needed for, for example, air conditioners, manufacturing processes or power generation. A cooling tower is an equipment usedto reduce the temperature of a water stream by extracting heat from water and emitting it tothe atmosphere. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly (Figure 1). Cooling towers are able to lower the water temperatures more than devices that use only air to reject heat, like the radiator in a car, and are therefore more cost-effective and energy efficient.
cooling tower Approach = what outlet temperature of the cooling tower - wet bulb temperature
calculate the duty of given ambient condition
calculation on mass flow rate, wet bulb temp, approach, range & condition of cooling tower installation.
The Cooling tower is installed where the continuous heat rejection is required. Like process plants. Type is depends up on use & water property.
There's quite multitude of things that impact a cooling performance. Specifically the height of the tower impacts on the the drafting air through the tower. See "Air Cooled Heat Exchangers and Cooling Towers" by Kroger for something more indepth.
air will flow through across cooling tower
cooling tower cleaning is required when the actual approach temp is significantly higher than the design. this may be due to fouling of spray nozzles of water distribution system and or fouling of fills media specially in film fill type cooling towers. This fouling materials is mainly consist of biofilms, calcium salts trapped in biofilm, dust & dirt. on line chemical cleaning followed by a good scale cum dispersant chemicals are required to control any further fouling of the cooling tower in future.

The Approach is the difference between wet bulb temperature and outlet water temperature from cooling tower. That means , in this case, Approach = 35-25=10 degrees.

Cooling load in kw is increase the temperature of the water before enter the cooling tower, thus the differential heat energy level is high compare to surrounding temp., so it will transfer heat more to surrounding and leave the tower with low temperature, and it will become more like to approach the wet bulb temp., this happens if the variables such the water flow, and the air velocity is kept constant.

There are dfferent types of cooling towers available in Industry. Some of the commonly is used cooling towers are Round Cooling Towers Square Cooling Towers Dry Cooling Tower Wooden Cooling Tower Cross Flow Cooling Tower Modular Cooling Towers Evaporative Cooling Towers Natural Cooling Towers Counter Flow Cooling Towers Get a highly durable cooling tower according to your industry.

The only thing that I've heard of with "wet cooling" in, is a wet cooling tower. A Wet Cooling tower for the closed-circuit cooling of water where the water to be cooled comes into direct contact with the cooling air dissipating heat by evaporation and air heating. The air draught required for cooling can be induced by fans or by the natural effect of the stack of the cooling tower building (natural draught cooling tower).So I don't know if that answers your question or not, but i hope it helps...
