The air-conditioning cooling tower of the central air-conditioning generally uses river water, ground water, and demineralized water as circulating water. The pH value of the river water is mostly neutral and does not scale. It is an ideal cooling water, but it is difficult to obtain. Although groundwater is easy to use, it is prone to scaling, difficult to clean, and labor-intensive and time-consuming.

At present, demineralized water is commonly used in air-conditioning cooling towers, and the demineralized water is mostly weakly alkaline. It is generally prepared by ion exchange technology, and Ca ²⁺ and Mg ²⁺ in groundwater are replaced with Na ⁺ . Continuous evaporation, the concentration of Na ⁺ in the water is also increasing, so the water needs to be changed once every 2 to 3 days. If the demineralized water is not replenished or replaced in time, it will easily lead to scaling, which not only corrodes the refrigeration equipment, but also affects the refrigeration effect. At the same time, the existing technology A large amount of waste water is produced during the preparation of softened water, which needs special treatment before being discharged into the sewage pipe network, which increases the operating cost.

Rainwater is usually neutral or slightly acidic, but it contains some particles of dust, which need to be precipitated and filtered before it can be used.
