Clean water and sanitary water, such as municipalities. Pure in this case means that the water is free from excessive amount of microbes and not cause disease. Mineral salts and other substances in the water does not have to be removed by water, sewage treatment plants, if they do not affect sanitary conditions. Mineral salts are undesirable in water used for many other purposes. This could include energy generation, heating buildings, beneficiation and processing of raw materials and production. The water is fit for human consumption is not always acceptable for use in boilers or cooling equipment.
Water is used in many types of cooling systems. Heat is the main use of water for air conditioning or refrigeration. Typical applications include once-through capacitors, open recirculating cooling systems that use cooling towers, evaporative condensers, cooling water systems, and air washers. In evaporative condensers, once-through systems and cooling towers, water removes heat from the refrigerant and then either wasted or cooled by partial evaporation in the air.
Knowledge of impurities in the water used in any of these systems AIDS to forecast possible problems and methods of their prevention.
The tower is usually located remotely; it becomes necessary to regularly inspect and clean tower according to the manufacturer's recommendations. A few hours each month spent on inspection of the cooling tower and maintaining it will pay dividends. Life tower depends on the following factors:
Structural materials
Place in the system
Location city or country
as a Rule, high-quality construction materials:
Tree
Concrete
Stainless steel
Fiberglass
These units is expected to last from 20 to 30 years if cared for properly. Less expensive units, made of galvanized steel, will work from 8 to 20 years. Of course, the tower of life will vary due to extreme weather conditions, the number of hours used each year, and the type of water purification. Suffice it to say that in order to get the most tower, cooling tower manufacturers want to make the tower as long as possible...
