Yunuo Cooling Technology will introduce several assembly methods of closed cooling towers to you.
Closed cooling tower, referred to as closed cooling tower, (also called evaporative air cooler, closed cooling tower) places the tubular heat exchanger in the tower, through the heat exchange of circulating air, spray water and circulating water to ensure Cooling effect. Because it is a closed cycle, it can ensure that the water quality is not polluted, well protect the high standard operation of the main equipment, and improve the service life. When the outside temperature is low, the sprinkler system can be stopped to save water. Pushing the implementation of energy conservation and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in metallurgy, aviation, electric power, chemical industry, machinery, petroleum, food, plastic, rubber and other industries in recent years.
The closed cooling tower originated from the evaporative cooler, which began in the middle of the last century, and gradually began to be used with the development of the chemical, metallurgical, and electronic industries. For evaporative cooling technology, as early as 250 BC, the ancient Egyptians already knew how to use water evaporation for cooling. In the last century, various countries have also carried out many aspects of research on evaporative cooling technology. In the 1970s, the emergence of the energy crisis made the application of evaporative cooling technology gradually paid attention. In the 1980s, when it was discovered that the catastrophic climate that posed a huge threat to human existence was related to the air-conditioning and refrigeration industry, passive cooling technologies such as evaporative cooling technology, which used natural conditions to obtain cooling capacity, developed rapidly. The American ASHRAE has established a technical committee called "evaporative cooling", which aims to promote the application of evaporative cooling technology, collect and publish data on the application, installation, operation and maintenance of evaporative cooling systems, publish specifications and standards, and affirm and reward Research on evaporative cooling, in order to promote the application of evaporative cooling equipment in the whole country.
The closed cooling tower is then sent to the air through forced convection between the spray water and the air, and the heat transfer of the spray water to the air reduces energy consumption; the two-layer cooling method uses air-cooled evaporation to absorb heat, and the cooling efficiency is high; it can be directly cooled Water, oil, alcohol, quenching liquid, salt water and chemical liquid and other media, no medium loss, stable composition due to the use of closed cycle. The medium is not affected by the environment and will not pollute the environment. It is mainly composed of the latent heat of the spray water evaporation and the sensible heat exchange between the spray water and the air. Because the cooled fluid is a completely closed circulation activity between the cooling tower and the process equipment Therefore, there is no phenomenon that debris enters the cooling pipeline system, and then the pipeline is blocked; the soft water is circulated for cooling.
At high temperature, there is never scale formation, which causes scaling in the cooling pipeline system. It is different from the general cooling tower in which the cooling fluid directly touches the air, so it is called a closed-circuit tower. Because the closed cooling tower is a fully enclosed circulating cooling, it occupies a small area, does not need to excavate a pool, is easy to locate, and saves water.
The above is the relevant content introduced by Uno Cooling Technology.
