As the air conditioning cooling water system scaling, corrosion and algae breeding is not formed in the short term, and will not have a devastating impact on the system in the short term, so often do not get enough attention from the operating managers.
Machine room precision air conditioning circulating cooling water treatment In addition, because the air conditioning cooling water system is relatively simple, the designers do not pay enough attention to it, and, cooling water treatment is the water supply and drainage professional and HVAC professional are related to the professional, and the cooling water system is mostly designed and implemented by HVAC professionals, so it is inevitable that the innate design is not reasonable. In the design process for air conditioning cooling water system is easy to scale corrosion and algae breeding characteristics, the treatment method is also different from the chilled water system. Cooling water treatment methods can be divided into chemical and physical methods.
At present, large cooling water systems mostly use chemical methods, which must be added to the cooling water scale inhibitors, corrosion inhibitors, algaecides and their supporting cleaning agents, etc., thus forming a full set of water treatment technology for cooling water. It can be used as a reference for the design of large air-conditioning cooling water treatment. As scale can ensure the heat transfer effect (energy saving), the level of corrosion inhibitors, algaecides can reduce equipment corrosion, extend the life of equipment are positive benefits, so the world's attention, the major foreign water treatment companies have this technology as the first focus to grasp, it is reported that in 1987 industrial water treatment agents (cooling water part) sales value of $586 million, the beginning of 1992 sales value of $765 million. Annual growth rate of 6%. In recent years, with the rapid development of China's national economy, the research and development of water treatment agents has also developed significantly.
The method was earlier applied to hot water boilers and ship water treatment, in recent years, the method is also used in cooling water systems, commonly used agents are mostly solid crystal silicate corrosion inhibitors by the film. Practice has proved that the following points need to be noted: different film agents require different dissolution temperature, for the dosing irrigation in the circulating water system, the water temperature can often reach the dissolution temperature, and for the dosing irrigation in the make-up water system, special attention should be paid to prevent the water temperature is too low, if the water temperature is too low, the dissolution of the film corrosion inhibitor is not good, it will affect the corrosion inhibition effect.
