Features Ji'an, Jiangxi closed cooling tower closed cooling tower closed cooling tower: 1. Closed cooling tower is a modification and development of traditional cooling tower. It is actually a combination of evaporative cooling tower, chiller and a wet cooling tower, which is a horizontal evaporative cooling towers, process fluid in the pipe flows outward through the air in the tube, the two do not touch. After the bottom of the reservoir water extracted by the circulating pump inside, rushed tube uniformly sprayed down. It is not in contact with the process fluid or refrigerant and the hot water pipe outside air into a closed cooling tower, spray water through enhanced heat and mass transfer effects. 2. Closed cooling tower suitable for high quality requirements of a variety of circulating cooling systems, electric power, chemical, steel, food and many industrial sector applications. On the other hand, compared with the air-cooled heat exchangers, evaporative cooling Tully by latent heat of vaporization of water pipe under the side of the air-side heat and mass transfer significantly enhanced, but also has obvious advantages. Closed cooling tower (also called evaporative air cooler) placed in the tube heat exchanger tower, through the air, spraying water and recycled water heat exchange to ensure the circulation of the cooling effect. Because it is a closed loop, which can ensure the water quality from pollution, well protected and efficient operation of the main equipment to improve the service life. When the outside temperature is low, water spray system can be stopped, play water-saving effect. Push increasingly scarce national energy conservation policy implementation and water resources in recent years, closed cooling tower in iron and steel metallurgy, power electronics, machining, air conditioning systems and other industries has been widely used. Northern winter temperatures are usually below freezing, run antifreeze closed cooling tower problems have become increasingly prominent, if not resolved, could be damaged by frost or cooling tower heat transfer tubes other components. Depending on the process characteristics, closed cooling tower and some winter run all day, and some part time run, some almost not. But we need to consider freezing problems.
