Cleaning of central air conditioning
1, air outlet cleaning cannot be ignored.

The shell and exposed part of the air conditioner body are the most easily polluted parts. Turn off the power socket of the air-conditioned room machine before cleaning, and it is best to unplug it directly. This is very important to avoid electric shock and leakage accidents. Gently open the two ends of the air conditioner shell, as long as you use a little force. If you can't open it by hand, you can use a screwdriver to help, but you need to master the skills, otherwise it will easily damage the shell.

After opening the air conditioning cover, wipe the exposed shell with a wet rag, and pay attention to some dead corners such as vents that are easy to attach dust when cleaning. When you start cleaning, scrub the panel first, gently scrub the dust on the panel with a rag, and pay more attention to details and seams to prevent dust from remaining in the dead corner. What needs to be cleaned in this link is the air guide page of the air conditioner outlet. In long-term use, because it is the air outlet of the air conditioner, the surface is very easy to attach dust, so it can not be ignored when cleaning outside.

2. The filter is the place where the core is clean.

The core part of cleaning air conditioner is filter screen.

Cleaning method of split air conditioner: open the cover inside the air conditioner, take out the filter screen, brush it with a clean filter screen to clean off most of the dirt attached to the filter screen, and then soak it in a mixed solution containing special cleaning solution for air conditioner or homemade cleaning solution or detergent and soap powder. Soak 10~20 minutes first, and then, depending on the dirty degree of the filter screen, if it is still dirty after soaking, gently brush the filter screen with a bottle brush to make each filter hole clear and transparent, without dirt and blockage traces, dry it with a special wiping cloth, and install the filter screen on the body after inspection. Then turn on the computer and check whether it works properly.

Cleaning method of cabinet air conditioner: first remove the panel of cabinet machine, find the evaporator of air conditioner, shake and spray the special foam cleaner on the evaporator of air conditioner, then cover the panel, let it stand for about 10 minute, turn on the air conditioner, adjust the air volume and refrigeration capacity to the maximum, and keep the air conditioner on for 30 minutes. In order to prevent the air outlet from blowing out some foam and dirt, you can cover the air outlet with a wet cloth.

Don't forget to clean and disinfect the radiator.

Behind the filter, there is also a heat sink, and the cleaning of the heat sink is a link that many people usually ignore in the cleaning process of air conditioning. When the air conditioner is running, the radiator will produce condensed water, so this part is in a humid state for a long time, which is easy to attach dust and more likely to breed bacteria.

Unplug the air conditioner and start cleaning. Spray the heat sink repeatedly with professional air conditioning cleaning agent for 2 to 3 times. It is recommended to spray it up and down, so that the coverage of cleaning agent can be more dense. Here, it is important to remember the parts behind and above the spray bracket. After evenly spraying the heat sink, wait for about 5 minutes, so that the cleaning agent can fully dissolve the dust on the heat sink and kill the attached bacteria. Then connect the air conditioner power supply, install the filter screen, cover the air conditioner cover, and let the air conditioner run for about 20~30 minutes to completely remove the dust and bacteria on the heat sink. Because a large number of germs are easy to accumulate on the air-conditioning radiator, families with children and sensitive people need to clean and disinfect the air-conditioning radiator once a month.
