According to the waste heat generated by the general central air conditioning or process equipment, the cooling circulation water is usually used to generate sensible heat (temperature drop) and latent heat (water vapor evaporation) in the cooling tower to exchange heat with the outside air to achieve waste heat removal Purpose. However, since most of the circulating cooling water comes from tap water, groundwater, soft water or reclaimed water, such water contains many dissolved ions that follow the supplemental water to enter the system. When the circulating cooling water evaporates, the concentration factor gradually increases. When the concentration exceeds its solubility in water, scale is generated as a result, and accumulates and adsorbs on the surface of the heat exchanger, resulting in a reduction in the efficiency of the heat exchanger, which in turn causes scale corrosion of the heat exchanger, slime and microorganisms to multiply, which not only consumes Energy, reduced production capacity and increased equipment maintenance costs may even cause the unit to shut down.
