Cleaning and maintenance method of central air conditioning filters
The long-term operation of central air conditioning will lead to the equipment being blocked by scale, which will reduce efficiency, increase energy consumption and shorten service life. If the scale cannot be removed in time, it will face the risk of equipment maintenance, shutdown or scrapping and replacement. For a long time, traditional cleaning methods such as mechanical method (scraping and brushing), high-pressure water and chemical cleaning (pickling) have many problems in the cleaning of central air conditioning: the scale and other sediments cannot be completely removed and cause corrosion to the equipment. The residual acid causes secondary corrosion or corrosion under the scale to the material, which eventually leads to the replacement of the equipment. In addition, the cleaning waste liquid is toxic, A lot of money is needed for wastewater treatment. Enterprises can use high-efficiency environmental protection cleaning agent to avoid the above situation. It has the characteristics of high efficiency, environmental protection, safety and no corrosion. It not only has good cleaning effect, but also has no corrosion to the equipment, which can ensure the long-term use of central air conditioning.
opinion
So, how can we achieve excellent cleaning effect? The cleaning and maintenance personnel of central air conditioner put forward several opinions:
1. First remove the dust filter screen according to the instructions. During disassembly, be careful not to touch the metal part of the indoor unit to prevent it from being scratched.
2. After removing the air dust filter, gently tap or use an electric vacuum cleaner to remove dust. If the dust filter screen accumulates too much dust, it can be rinsed with water or cleaned with a soft brush dipped in neutral detergent, but the water temperature during cleaning shall not exceed 50 ℃, and washing powder, detergent, gasoline, banana water, etc. shall not be used to avoid deformation of the dust filter screen. In addition, do not clean with a sponge, otherwise the surface of the dust filter will be damaged.
3. After washing with clean water, wipe dry with a soft cloth or blow dry in a cool place. Never expose yourself to the sun or dry in an open fire such as a stove to avoid deformation of the dust filter.
4. When cleaning the panel, gently wipe it with a soft cloth dipped in warm water or neutral detergent, and then dry it with a dry soft cloth.
