The operation of the central air conditioning system requires a large amount of water as the conductive medium. Long-term operation of water in the system and other reasons can cause problems such as corrosion of unit equipment, scaling, growth of microorganisms (bacteria, algae) and slime deposition. These problems will not only increase the energy consumption of the air conditioner, but also affect the air conditioner. The normal and stable operation of the system will shorten the service life of the system. Therefore, necessary cleaning and water quality stabilization treatment must be carried out on the cooling water and chilled water systems to maintain good conduction efficiency, extend the service life of the equipment, and enable the unit to operate in an efficient, safe, and stable state. In particular, central air-conditioning systems that are newly put into operation or that start operating in a new cooling season need to be cleaned and pre-filmed.
