Cooling towers are primarily used for heating, ventilation, and air conditioning (HVAC) and industrial purposes. It provides a cost-effective and energy efficient operation of systems in need of cooling. More than 1500 industrial facilities use large quantities of water to cool their plants. HVAC systems are used typically in large office buildings, schools, and hospitals. Industrial cooling towers are larger than HVAC systems and are used to remove heat absorbed in the circulating cooling water systems used in power plants, petroleum refineries, petrochemical plants, natural gas processing plants, food processing plants and other industrial facilities.
Industrial processes and machines generate such large amounts of heat that continuous dissipation is necessary for efficient operation. The heat must be to the environment. This is through a heat exchange process which is the basis of the cooling tower technology.
It is interesting that despite cooling towers being devices of the 20th century, knowledge about them is actually limited. Some people believe cooling towers are sources of pollution, yet the only thing they release to the atmosphere is water vapor.
After many years of development of this technology, cooling towers are available in different types and sizes. Each of these is applicable in a certain load configuration, the reason it is important to outline the options available. Note that despite the different designs, the basic function remains as that of dissipating heat from a building system or a process to the air through evaporation. Here are some categorizations:
A.Mechanical draft cooling tower
B.Atmospheric cooling tower
C.Hybrid draft cooling tower
D.Air flow-characterized cooling tower
E.Construction-characterized cooling tower
F.Shape characterized cooling tower
G.Cooling tower based on method of heat transfer
Each of these could carry several cooling towers. For instance, categorizing cooling towers in terms of heat transfer method gives three options: Dry cooling towers, Open circuit cooling towers and Closed circuit cooling towers/ fluid cooling towers.
Cooling towers maybe generally cost-effective for industrial cooling compared to the other options, but efficiency challenge can be a letdown. Monitoring the efficiency factor is crucial as it ensures the following:
►Reduced water consumption
►Extended equipment service life
►Reduced operation costs
To keep the cooling tower running efficiently, three things are important: understand the type of cooling tower you are using, use chemicals efficiently and track down system water loss.
The cooling tower system is common in many industries, chief among them being power, commercial, HVAC and industrial. In the industrial setup, the system rejects heat from machinery, heated process material among other sources. Specifically, industrial cooling towers are common in food processing plants, petroleum refineries, natural gas plants and petrochemical plants.
Other industrial applications:
►Water cooled air compressors
►Plastic injection & blow moulding machine
►Die casting machine
►Refrigeration and chilling plant
►Anodizing processes plant
►Electrical power generation plant
►Water cooled air conditioning systems and VAM machines
Choosing a cooling solution is a kind of overall consideration of cost, space, noise, energy bills and water availability. If you are unsure which model you need, please contact us for more guidance freely.
