Basic knowledge of Dongguan central air-conditioning cleaning


In Dongguan central air-conditioning cleaning, the circulating cooling water continuously evaporates and scatters, causing the ion concentration to increase and the hardness to increase. When the hardness of the circulating cooling water exceeds 500 ppm, the concentration of the circulating water exceeds the normal range, and the electrolyte concentration in the water will rise sharply. High, severe galvanic corrosion on metal pipes. Pollution is to discharge the circulating cooling water with high hardness to reduce the content of hardness ions in the water and reduce the scale components in the water, so that the water quality reaches a balanced state between corrosion and scaling. Therefore, blowdown is a necessary step in daily water treatment.
The chemical cleaning methods of Dongguan central air-conditioning cleaning can be divided into single cleaning and system cleaning. The former refers to the cleaning of some single equipment, and the latter refers to the cleaning of the entire cooling water system in contact with the cooling water.
Dongguan central air-conditioning cleaning of certain equipment with severe corrosion, fouling or slime deposits often causes the unit to overheat and trip. A single cleaning can be considered, but the cleaning of a single device requires strict control of various water treatment indicators, otherwise it is easy to cause various Kind of corrosion. Therefore, it is recommended that customers try to avoid the single cleaning process by themselves. They should consult the professionals with experience in water treatment before handling it! Equipment that often performs a single cleaning includes: air compressors, various small heat exchange equipment, etc. Most of the central air conditioning circulating water systems use full system cleaning.
