Cooling water tower, cooling towers, or cooling ponds are used worldwide to provide cooling to the buildings of a city by evaporating water in heat exchangers. To do this they take advantage of the temperature difference between the cooler ground and warmer air. It is estimated that globally more than 1 billion people live in areas served by an artificial cooling towers.
A typical operational cycle is as follows:
water at higher temperatures leaves a fixed-shell evaporative condenser on the roof or side of the building where it cools down quickly and then enters a vertical tube coil made up of horizontal tubes joined together in parallel. The water then passes between two sets of slats in a porcelain-lined horizontal plane, which is coated with insulation. The perforated outer covering allows evaporative cooling to take place. This occurs because the evaporation takes place at a higher temperature than the air inside the tower itself.
Some tips before installing a cooling water tower:
1. Before cooling tower installation make sure the surface is flat and inspect the soil’s bearing capacity.
2. It should be installed in a quiet place with enough area for it to cool down.
3. Make sure that the area is non-polluted and has no leakage pipes.
4. Install the tower body with the insulation board facing upwards and screw the base plate tightly to make sure there is no leakage. Then, connect the water pipe with the water source during the construction period and check the pipe connection before it is filled with water.
5. The pipe connection of the cooling tower should be raised above the uppermost part of the tower and its head must be higher than the pipe connection.
6. In areas with a height difference exceeding 1.5 m, install an expansion joint or flexible coupling to allow for thermal expansion or contraction.
7. Make sure that all pipe connections are water-proofed, especially those in the tailpole area.
8. It should be installed on flat ground, not on slopes, and stabilizing anchor bolts must be installed before construction to connect it tightly with the ground (or building) and make sure there is no leakage around the water tower body itself and between pipe connection and concrete foundation after construction.
9. Install a wastewater discharge pipe in the tailpipe area to prevent leakage.
10. If you build it on the roof, make sure there is little air movement around the tower and that there is space for the required ventilation system.
11. Masking tape or other methods to prevent bird and animal entry should be used during installation to prevent damage from birds and other animals that can cause injury or death to young children and others who come near it. Also, rocks must not be placed in the storage tank area of water cooling towers as they can damage water pump impellers causing them to break down over a long period.
On a concluding note, water cooling towers are not only effective but also flexible in their application and thus can be used to cool many various types of structures, large and small. Cooling towers can be found in many construction projects such as cafes, buildings, offices, supermarkets, shopping malls, hospitals, etc. The advantage of using a cooling water tower over a traditional air conditioning system is the fact that water cools down more quickly than air cools down which means that less energy is wasted. Water cooling towers can be installed in modern buildings just by adding on-site or off-site infrastructure and by working with local municipal authorities and experts to install them properly.
