What is a dry cooling tower and how does it differ from other cooling tower applications?
What Is A Cooling Tower?
A cooling tower can be thought of as a specialized heat exchanger where water and air meet with the purpose of reducing the temperature of the water. When this happens, a small total of the water evaporates, hence reducing the water temperature that is circulated throughout the tower.
This water is pumped through pipes to the cooling tower. Nozzles are used as the water sprays onto material known as fill that slows the flow of the water as it travels through the cooling tower and maximizes air and water contact. When they meet, a cooling action is created and the cooled water is then pumped back to the processing equipment where it absorbs hear. From there it is pumped back to the cooling tower and obviously, cooled again.
Dry Cooling Tower Guide
This closed-circuit cooling tower operates by transferring excess heat from the system. Dry cooling towers efficiently transfer heat through a surface separating ambient heat and working fluid. Either water or a mixture of water-glycol is the medium used within dry cooling towers. The principle of heat transfer essentially takes place by heat exchanger with extended fins. Air may be introduced through natural or mechanical draft to effectively move air through the air-cooled heat exchangers.
Unlike most other cooling towers, these towers utilize evaporation. As a result, the consumption of makeup water is miniscule. Also, the fan within the system uses an electric motor for operation. The system functions with air colling technology and the circulation of hot water enables the heat exchange because the tubes are exposed to the ambient air flow that ultimately surround them.
There is an increase in volumetric flow rate of air through the heat exchangers that offers an improved performance. Meanwhile, one of the downsides of this system is a lower efficiency, especially when the ambient air temperature is very high. The tower has been designed with controlled expansion of both the tube and fin, which will provide a smooth and clean tube for water pressure droppage. The motors are designed specifically to keep the efficiency high with dust, rain, and moisture resistance.
Dry Cooling Tower Applications
Because of their different performance ranges, it is quite possible that a dry cooling tower is best for your industry. Ranged from 5-2, kW performances, these systems feature different noise levels and are mainly designed for outdoor installation. Dry cooling towers are often used by the plastic, power plant, and solar industries.
You can use these cooling towers in computer room air conditioning systems and water-cooled chilled water air conditioning systems, as well. Specifically, this tower application works well in places with scarce water resources. They can help eliminate excess heat without damaging the outside environment.
Regular maintenance is necessary with these cooling towers. Keeping up with maintenance needs will prevent future damage and avoid total compressor failure. When this system runs efficiently, both energy consumption and costs will plummet.
