What is the central air conditioning cleaner?

 

The central air-conditioning cleaning agent is used for cleaning and descaling of the central air-conditioning cooling circulating water side, and finally the central air-conditioning cooling circulating water side is cleaned, the cooling efficiency of the circulating water is improved, the cooling effect of the central air-conditioning is restored, and the power of the engine is saved, and the central portion is extended. The service life of the air conditioner.

How to use central air conditioning cleaner?

 

1, cleaning process: water washing → central air conditioning cleaning agent descaling → water washing → passivation;

 

2. Disconnect other systems unrelated to the cooling coil, and connect the cleaning tank, the cleaning pump and the cooling coil into a cleaning closed loop;

 

3. Check the leakage of the cleaning system under the simulated cleaning state, and remove the loose dirt in the coil. When the flushing water at the outlet is visually observed, there is no large particle impurity, and the water washing ends;

 

4. Add “central air conditioner cleaning agent” in the cleaning tank to control the concentration of cleaning main agent in the range of 3-6%, temperature in the range of 50-60 °C, and perform circulating cleaning and decontamination in the system. Cleaning time 2-3 Hours or so. The pH value of the acid solution is measured periodically with a pH test paper (1 time / 20 minutes) to maintain it below 1 , and when the pH value tends to be stable within half an hour and no gas is released in the cleaning system, the pickling process is terminated;

 

5. After the cleaning process is completed, rinse with water to rinse the residual sludge and residue. When the impurities at the outlet are not much, and the pH is greater than 6, the water rinse is finished.

 

6. After the water is rinsed, the “passivation pre-filming agent” is added cyclically for passivation treatment to improve the corrosion resistance of the copper tube. After the concentration of the entire system solution is evenly mixed, the cycle is stopped and soaked for 2-3 hours. The passivation solution is drained out of the system and the cleaning process is complete.
