Dongguan central air-conditioning plays a pivotal role in regulating temperature. After long-term operation of the air conditioner, scale, rust, and dust problems inevitably appear in the chilled water, cooling water system, refrigeration host, and fan cooling plates of the air conditioner:
Corrosion: The cooling and frozen water of the air conditioning system is extremely corrosive without treatment. If ordinary steel sheets or iron nails are put into water, rust will appear after a few days. The longer the time, the more severe the rust will be. The inner wall of the equipment often causes rust and slag to fall off due to corrosion, and even the perforation. The rust and slag that has fallen off will block the coil and reduce the cooling effect. At the same time, the existence of corrosion will greatly shorten the service life of the equipment.
Scaling: Crystals of inorganic salts dissolved in water in the pipe precipitate out, and scales are formed on the pipe wall of the heat exchange surface such as the condenser, which leads to a decrease in heat exchange efficiency and a decrease in refrigeration effect, and in severe cases, it decreases by 30%. At the same time, if hard dirt increases, the power consumption or fuel consumption increases, and in severe cases it increases by 35%.
Biological slime: due to the formation of dirt by water, mud, sand, humus, and biological slime formed by bacteria and algae and their secretions, the pipeline will be blocked in severe cases; and dirt and slime will affect heat Exchange efficiency, more power consumption, causing high-voltage operation, causing severe over-pressure shutdown. All of these seriously affect the normal operation of the air conditioning system.
Therefore, the problems of scale, rust, silt, bacteria and algae in the central air-conditioning system in Dongguan will directly reduce the cooling capacity, shorten the service life, reduce the operational reliability, and increase the energy consumption, resulting in increased operating costs. In order for Dongguan central air-conditioning system to operate in an optimal state, special chemical and pharmaceutical treatments must be performed on the cooling and freezing water systems of the air-conditioning system: removing scale, rust, slime, sterilization and anti-corrosion treatment, the significance lies in:
Save energy and reduce operating costs. During the heat transfer process of the evaporator and condenser of the Dongguan Central Air Conditioner, the dirt directly affects the heat transfer efficiency and the normal operation of the equipment. The operation results of the Dongguan Central Air Conditioner unit show that the air conditioning unit without cleaning uses electricity or fuel after running for a period of time. Consumption will increase by 10-30%, prolong service life, and reduce equipment depreciation and usage fees.
Dongguan central air-conditioning cleaning can reduce accidental shutdowns and improve cooling results. Dongguan central air-conditioning cleaning can remove sludge, make the pipeline unobstructed, and the water quality is clear. At the same time, descaling and antiscaling improve the thermal efficiency of the condenser and evaporator, thereby avoiding the phenomenon of high pressure operation and overpressure shutdown, increasing the flow of frozen water, improving the cooling effect, and making the system operate safely and efficiently.
