The cooling tower can also be referred to as a heat rejection device. Numerous commercial entities and industries will have use of such towers and need to fall back on the work that existing cooling tower service companies are able to afford them. The cooling tower essentially rejects waste heat going into the atmosphere. It does so through the cooling of a water stream to a lower temperature. Cooling towers could utilize the evaporation of water to eradicate processed heat.
It could also cool working fluid near its wet-bulb air temperature. In the case of closed circuit dry cooling towers, it could rely solely on air to cool working fluid to near its dry-bulb air temperature. There will be common applications made. These could include cooling circulating water used in oil refineries, petrochemical and other chemical plants. Applications could be made to thermal power stations.
Applications could be made to nuclear power stations, as well as to HVAC systems that are being used to cool buildings. Classifications of such applications will be based on the type of air induction that filters into the tower. The main types of cooling towers are characterized as natural draft and induced draft cooling towers. Such towers will always vary in size. They can occupy small roof-top units.
They can be amassed as quite large hyperboloid structures that could be up to 660 feet tall and 330 feet in diameter. They can also be built as rectangular structures that could stand at 130 feet tall and 260 feet long. Hyperboloid towers are common with nuclear power plants but so too with coal fired plants, as well as chemical and many other industrial plants. But in the main, most cooling towers being built are significantly smaller.
