Central air-conditioning cleaning two methods

1. Cleaning of Central Air Conditioning Ventilation System a. Inspection of air conditioning system Before and after cleaning, monitor and record the pollution of the inner surface of the air duct with the monitoring equipment, and save the pictures for inspection and acceptance.

b. Indoor air quality testing According to the national testing standards, the air conditioning system is tested to check the hygienic conditions in the air conditioning system.

c. Cleaning of air ducts In strict accordance with GB19210-2003 "Code for Air Conditioning and Ventilation System Cleaning" and National Air Conditioning Cleaning Association's NADCA standard, airborne rotating brushes of different materials and sizes are used to clean the pollutants in the air conditioning system, and then the vacuum cleaner will be used. Pollutant removal.

d. Disinfection and purification of air ducts After the dirt is removed, the entire air duct is cleaned and disinfected with the US Air Conditioning Agency (EPA) registered special air-conditioning disinfectants and deodorant products.

e. After cleaning up the site cleaning project, collect all the tapes and garbage left over from the project to ensure that it will not affect the daily work.

f. Service follow-up includes mechanical inspection of air-conditioning ducts and measurement of pollutants in indoor air, which can provide management with real data and information to assess and improve the quality of indoor air and propose effective solutions.

2, central air conditioning water treatment a, adding bactericidal agents by adding bactericidal agents, remove the circulating water of various bacteria and algae.

b. Adding a stripping agent and adding a stripping agent to peel off the biological slime in the pipeline, and wash the slime out through the cycle. c. Add a comprehensive chemical cleaning agent to add a comprehensive chemical cleaning agent. The cleaning agent has the functions of corrosion inhibition, dispersion, and descaling and processes the water circulation system. This treatment method can not only disperse the rust, scale, and oil in the pipeline after being cleaned, but also prevent the cleaning agent from harming the system device and the pipeline, and provide a clean metal surface.

d, input pre-film agent into the pre-film agent, the formation of a dense polymeric polymer protective film on the metal surface, in order to play a role in anti-corrosion protection.

e. Add a comprehensive daily curing agent to add a comprehensive daily curing agent, which has the function of corrosion inhibition and metal rust prevention. The daily curing agent contains a polymer complex scale inhibitor, which prevents the precipitation of calcium and magnesium ions through the complexation action, prolongs the service life of the unit, saves water and electricity, and improves the cooling efficiency. In addition, regular sampling should be conducted to monitor water quality
