WORK WITH WATER COOLING PROBLEMS
Three-quarters of earth's surface is covered with water. The earth is covered with water vapor, which is an integral part of the atmosphere. Heat from the sun shining on the oceans, rivers and lakes, part of the water evaporates into the atmosphere. Warm, moist air rises and cools. Cooling the steam condenses in the form of clouds. Wind currents carry clouds over the land, where rainfall can occur in the form of rain, snow or wet snow. For the sun and upper-air currents, this process is repeated again and again. Pure water has no taste and no smell. Clean water, however, it is actually rare.
All water found in oceans, seas, rivers, lakes, streams and wells contain different amounts of minerals picked up. Even rain water is not very clean. As the rain falls on the earth, it washes out of the air and various gases and solid particles such as oxygen, carbon dioxide industrial gases, dust, and even bacteria. Part of this water goes into the ground and collects in wells or forms of underground streams.
The remainder is working on the land, and finds his way back to the variety of the surface of the water.
Water is often referred to as the universal solvent. The water flows over and through the ground and mixed with many minerals. Some of these mineral particles dissolved or under the influence of water. 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 cooling or air-conditioning equipment. Typical applications include once-through capacitors, open recirculating cooling systems that use cooling towers, evaporative condensers, СЃ chilled water systems and air washers. In evaporative condensers, when using 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 of stay in the examination of the tower, and maintaining it will pay dividends. Life tower depends on the following factors:
- Building 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 maximum benefit from the tower, cooling tower manufacturers want to make the tower as long as possible...
