Chemical cleaning methods for central air-conditioning condensers, chillers, heat exchangers etc.

Chemical pickling and descaling method: Clean the condenser, chillers, heat exchangers etc. with a prepared weak acid descaling agent to make the scale fall off and improve the heat transfer efficiency of the condenser.

The method of operation is:

Prepare the descaling solution in the pickling tank and start the pickling pump to make the descaling solution circulate in the condenser tube of the condenser. Under normal circumstances, the scale will be basically removed after no more than 4 hours.

After stopping the work of the pickling pump, use a blasting machine to clean the tube wall of the condenser for a second time to wash away the scale and rust.

Wash the descaler solution remaining in the tube with clean water repeatedly until it is completely clean. The chemical pickling and descaling method is suitable for vertical and horizontal shell and tube condensers.

The significance of descaling and energy saving:

Once the condenser is scaled, the heat conduction resistance increases, so the thermal resistance increases, and the heat transfer coefficient value will decrease. Because the condensation temperature is inversely proportional to the heat transfer coefficient, the temperature of the condenser rises and the condensation pressure increases accordingly. And the more serious the fouling of the condenser, the more condensing pressure will increase significantly, which will increase the power consumption of the refrigerator, and cause the corresponding increase in the power consumption of the operating equipment of the refrigeration system, resulting in a waste of electricity.
