How does York Air Conditioning manage the operation of cooling towers?
In terms of operational management of cooling towers, the water quality of the cooling water system is an extremely important issue. Some cooling water systems are connected to the atmosphere, and pollutants in the air such as dust, debris, bacteria, and soluble solids may enter the circulating water system at any time, causing excessive reproduction of microorganisms, resulting in biological sludge. Meanwhile, if the make-up water for the system has not been softened, the salt content of the part of the water that evaporates in the cooling tower will remain in the cooling water system. Therefore, as the evaporation process continues, the dissolved salts in the circulating cooling water are constantly concentrated, thus increasing the hardness of the water. In addition, the effect of dissolved oxygen in the water outlet causes scaling and corrosion of metal pipes. Cooling water quality control indicators:
pH value: 6.5~8.5;
Turbidity: Maximum allowable content 200 [mg/l];
Carbonate hardness: 8~30 degrees (referring to German degrees).
The most effective water treatment method is chemical cleaning, which involves regularly adding cleaning agents to the system based on the condition of the water quality to ensure that the water quality meets the required standards. Using softened water that has undergone water treatment as make-up water is the ideal water source for a cooling water system.
