[0002] The central air conditioning water is repeatedly recycled in the circulation system. Due to the increase in water temperature and evaporation, the soluble substances in the water are continuously concentrated. The water collection pool of the cooling tower is polluted by wind, sun, rain and various external environments, which will produce more serious sediment adhesion, equipment corrosion and large-scale microbial growth than the direct cooling water and closed cooling water systems. As a result, the pipes are blocked by mud and dirt, resulting in an increase in scaling and corrosion tendency in the cooling system, posing a hidden danger to production safety. For this reason, it is necessary to discharge the concentrated water, add some fresh water and water treatment agents, and maintain water balance and stable water quality.
