1. Remove the debris of the ventilation and ensure that the ventilation is normal.Observing the phenomenon of not loosening the outdoor unit, and there is no foreign body in the cleaning outdoor unit and ventilation net cover.
2. The surface of indoor and external heat exchangers is cleaned to improve the efficiency of the heat exchanger.When cleaning up the indoor heat exchanger, you should be careful to take the lower plate, scrub it with a soft rag, and use a small brush to gently wash the heat exchanger of the inner machine to achieve the purpose of clearing the harmful accumulation of dust and breeding bacteria.However, note that because the heat dissipation film is a very thin metal material, it is easy to deform after stressing, so you must brush it carefully.
3. Clean the ash on the filter.When cleaning the filter, first cut off the power and then open the wind grille; remove the filter and clean the filter with water or vacuum cleaner.net.Do not use pesticides or other chemical detergents to clean the filter.
4. Clean the dirt and accumulation of the drainage part.Clean up the accumulation of the drainage part, clear the drainage pipeline to ensure smooth drainage.
5. Wash the harmful substances in the air, disinfect sterilization, beauty.Washing air -conditioning fan and accessories, clean and dust removal with professional air -conditioning washing agents.
Precautions for cleaning of tall space air -conditioning units
1. In the process of cleaning, prevent the deformation of the heat sink and replace the capacity of the heat exchanger.
2. Do not use organic solvents such as gasoline, toluene, alcohol and liquid cleaning cream tanks and evaporator surfaces with strong acid and alkali, so as not to damage the surface of the plastic parts.
3. The stagnant water in the air duct should be excluded, and the fan plate filter should be cleaned once a month.
4. If it is a central air -conditioning system, during the summer refrigeration work, the cooling tower and pump should be washed every month. When the central air -conditioning system is discontinued in winter, the central air -conditioning water systems pipeline should be washed to remove the rust residue in the pipeline to ensure that the coming year will come in the coming yearSummer use is safe.
5. When there are a lot of dust indoor air, it should be regularly cleaned and returned to ensure that the wind speed is normal.
6. When the central air -conditioning or cleaning agent solution is cleaned on the surface and related equipment, the indoor fan needs to be turned off.During the cleaning process, please be careful not to let the water or cleaner solution penetrate into the host, end device or controller.
7. When replacing lubricating oil in the central air -conditioning system, the entire system should be used to clean the entire system.
In short, the cleaning skills and precautions of the high space air -conditioning unit are very important. It is necessary to regularly clean and maintain equipment to ensure its normal operation and improve the efficiency of use.At the same time, we need to pay attention to safety issues to avoid accidents caused by improper operation.
