Matters and methods of central air conditioning cleaning in Dongguan
Dongguan central air-conditioning cleaning generally includes chilled water, cooling system cleaning and descaling, water treatment, lithium bromide unit internal cavity cleaning processing, replacement of new solutions, old solution regeneration, central air-conditioning fan coil cleaning. Fouling and clogging are hard and difficult to clean, and the tubes are severely blocked, even more than 20% of the tube bundle, and a small diameter heat exchanger (the diameter of the tubes is less than 12 mm).
1. By adding bactericidal agents to the circulation system, remove various bacteria and algae in the circulating water.
2. Add a stripping agent to peel off the biological slime in the pipeline, and wash the slime out by circulation.
3. Add chemical cleaning agent, dispersant, clean the rust, scale and oil in the pipeline system, disperse and discharge it, and restore it to a clean metal surface.
4. Put in pre-film agent to form a dense polymer protective film on the metal surface to prevent corrosion.
5. Add corrosion inhibitor to prevent metal from rusting, and add scale inhibitor at the same time to prevent precipitation of calcium and magnesium ions through comprehensive action. And regular sampling tests to monitor water quality.
Dongguan central air-conditioning cleaning method:
It should include three parts, 1. the air-conditioning body shell and the exposed part, easily contaminated parts; 2. the filter cleaning, which is the most important part of the core; 3. the condenser and evaporator parts.
The first step of cleaning the central air conditioner in Dongguan: First, open the air conditioner indoor unit cover, remove the filter, and brush with a clean filter brush to clean most of the dirt attached to the filter.
Dongguan Central Air Conditioner Cleaning Step 2: Soak it in a special liquid containing air conditioner cleaning solution or homemade cleaning solution or a mixture of detergent and soap powder for 10-20 minutes, depending on how dirty the filter is After finishing using the bottle brush, gently brush the filter to make each filter hole clear and transparent, and there are no signs of dirty plugging.
The third step of cleaning the central air conditioner in Dongguan: Dry it with a special cleaning cloth, check that it is intact, and install the filter to the body, depending on whether the operation is normal. If it is normal, you can sign for acceptance, and the cleaning work is over. The cleaning of domestic central air-conditioning is beneficial to improve the cooling efficiency; it is beneficial to improve the cooling effect, to extend the life of domestic air-conditioning equipment, to improve the energy-saving effect, to the health of users, and the effect is healthier and more ideal than "healthy air-conditioning".
