The importance of water treatment in air conditioning water systems

1. Improve heat exchange efficiency, save energy, and reduce consumption.

. According to foreign data, for every 0.1mm increase in sediment on the surface of the condenser, the heat exchange efficiency can generally be reduced by 20-30%, while the power consumption increases by 4-8%

2. Protect equipment and extend its service life. The relevant data and experimental results of our center indicate that the corrosion rate of untreated cooling water on carbon steel is greater than 0.5mm/a, while the corrosion rate of treated cooling water on carbon steel is less than 0.1mm/a, which can effectively protect equipment and extend its service life

3. Reduce the frequency of daily maintenance to ensure the normal operation of the system. After long-term operation of the untreated circulating water system, the surface of the condenser deposits

The Baijiawang Research Institute is committed to creating an air conditioning water testing and water quality testing institution
