How to avoid summer "air conditioning disease", these deep cleaning tips
Abstract: Nowadays, most people keep the cleaning power of air conditioners at the filter level. In fact, doing so cannot completely remove the pollution caused by air conditioners. Because the filter only filters a part of the dust, there will still be some dust accumulated on the heat sink through the filter, and a large number of germs will accumulate. After understanding the real cause of the air conditioner pollution, we can clean the air conditioner each time by doing 1 more Step, clean the filter screen and also clean and sterilize the air conditioner heat sink, so as to effectively prevent the bacterial growth of the heat sink from polluting the indoor air. Therefore, the following editor will share with you a more comprehensive air conditioner cleaning steps, hoping to help you.
1. Filter cleaning
Open the window, ventilate, first wipe the air conditioner shell with a rag, then open the shell, remove the filter, use the water pipe to rinse it with tap water, do not use detergent or something, just rinse it directly, if the water flow is not fast enough When the dirt cannot be washed down, you can adjust the shower head in the bathroom to the fastest water flow level, and then rinse it, usually it can be rinsed clean; after rinsing, put it in a cool place to air dry, do not expose it to the sun, the filter is usually Plastic, can't stand high temperature. Finally, after the filter is dry, put it back into the air conditioner and close the air conditioner housing.
Matters needing attention: The filters of most air conditioner indoor units are made of plastic, so do not soak the filters with detergents or disinfectants that are too oxidizing to avoid embrittlement or damage of the filters due to oxidation. Brush with too much hardness to avoid breaking the filter. When cleaning, be sure not to use a brush or the like, which will make the filter eyes of the filter large, which will damage the filter and affect the use effect of the air conditioner.
Second, the heat sink cleaning
1. Cleaning part: the surface of the heat exchanger
Refers to the dirt on the inner and outer surfaces of the fins of all heat exchangers related to the heat exchange efficiency of the evaporator and condenser of the coil fin air conditioning equipment in this standard.
2. Air supply mechanism
Refers to the coil fin type air conditioning equipment in this standard, except for the two heat exchangers of the evaporator and the condenser, the air inlet components, filter components, air supply components, air ducts and hoses, air outlet components, condenser components assembled together. Dirt on the inner and outer surfaces of all relevant air supply mechanisms that affect the air conditioning quality of the equipment, such as water trays, body shells, etc. (except for the installation of extended air ducts).
3. Cleaning tools
(1) Air conditioner cleaning agent, plastic case cleaning agent;
(2) (cleaning the air duct of the air conditioner), Baijie brush (cleaning the aluminum fin of the air conditioner);
(3) scouring pads (2-3), screwdrivers and other tools.
4. Cleaning step
(1) First, remove the air deflector and filter; remove the middle frame screws to remove the casing, remove the remote control signal receiving board; remove the temperature sensor, and remove the air guide vanes.
(2) Put on the air conditioner waterproof cover and spray the air conditioner cleaning agent to clean the aluminum fins;
(3) Spray the plastic case cleaning agent to clean the wind wheel and brush the air-conditioning wind wheel;
(4) Brush the aluminum fins of the air conditioner, rinse the air conditioner fan, and clean the air conditioner drain.
3. Cleaning of the evaporator
The cleaning of the evaporator requires the use of a special cleaner. Shake well before use, and then spray evenly on the evaporator at a distance of about 5 cm from the evaporator until it is completely covered by the cleaning foam, wait for 15 minutes, and install the filter. Run the air-conditioning refrigeration program for 15-30 minutes, so that the sewage will be automatically discharged with the drain pipe.
4.the condenser cleaning
Don't think that the whole cleaning process is over now! We still have a very crucial step in the end, which is the cleaning of the air conditioner condenser. When cleaning the condenser, we need to pay attention not to splash the cleaning liquid on the parts other than the air conditioner, especially the key parts such as the built-in circuit board of the air conditioner. It also needs to be avoided, so as not to cause the short circuit of the electric board, causing failure and affecting the use. First, choose a special cleaning agent for household air conditioners. After taking out the filter, you can see that the air conditioner condenser is sprayed with cleaning agent, install the filter, close the panel and let it stand for 10 minutes, turn on the air conditioner and adjust the air volume and cooling capacity to the maximum, keep the air conditioner turned on for 30 minutes, the whole The process of cleaning the air conditioner is complete
5. Wind wheel cleaning
The wind wheel is the place where the most dust and dirt are deposited. Because there are many grooves and gaps on the wind wheel, the dirt is easy to accumulate here. Too much clogging of the dirt will not only breed bacteria but also affect the air output. Therefore, it must be cleaned as a key point, carefully scrub with a brush, and finally rinse it with a high-pressure water gun.
6. Outdoor unit cleaning: be careful with more circuits
The outdoor unit of the air conditioner is generally difficult to clean. It hangs outdoors, and the floor is relatively high, which is very dangerous. Therefore, the editor does not recommend that you clean it by yourself, but considering that there are many people who love to "make machines", The editor will also briefly introduce to you. I would like to mention here that although the cleaning of the outdoor unit is more troublesome, we cannot ignore the benefits of cleaning the outdoor unit. Keeping the frequency of cleaning the air conditioner once a year can effectively improve the The cooling effect of the air conditioner can also play a role in saving energy.
When cleaning the outdoor unit of the air conditioner, first cut off the power supply of the air conditioner to prevent electric shock. You can directly rinse it up and down with tap water, just rinse the fin-shaped aluminum foil heat sink of the outdoor unit of the air conditioner, that is, the temperature exchanger. When rinsing, the right side of the outdoor unit of the air conditioner should also be rinsed. You can also use a brush to scrub the fin-shaped aluminum foil heat sink of the outdoor unit from top to bottom, that is, the temperature exchanger. After cleaning, check the outdoor unit of the air conditioner, and check whether the frame screws of the outdoor unit of the air conditioner are loose. If it is loose, tighten it and reinforce it. If the frame is severely corroded, it should be replaced immediately. The collapsed heat exchange fins can be carefully trimmed with tweezers.
7. Disinfection method
Air conditioner disinfectant (for wall-mounted machines)
1. Turn off the power supply of the air conditioner, unplug the plug, and open the window to keep indoor air circulation;
2. Open the surface panel of the air conditioner, remove the filter screen and air purification filter (some air conditioners have it, see the air conditioner manual), and expose the heat sink;
3. Pull off the top safety piece of the nozzle, shake the bottle and can fully, and spray the entire heat sink in the order up and down at about 5cm away from the heat sink;
4. Wait for about 15 minutes after spraying, and use high-temperature steam to press inward and flush the swag attached to the fins into the waterway. After the filter is installed, run the air conditioning refrigeration program for 15-30 minutes, and the sewage will be automatically discharged with the drain pipe.
Air conditioner disinfectant (for cabinet machine)
1. Grille type air conditioner: Turn off the power supply of the air conditioner, unplug the plug, and see the heat sink through the air conditioner outlet baffle or open the panel at the lower air inlet.
Slider type air conditioner: Turn on the air conditioner, slide down the slider and let the air flow normally, unplug the plug and cut off the power, and see the heat sink through the baffle of the air conditioner outlet.
2. Insert the spray pipe at the nozzle, pull off the safety piece on the top of the spray head, shake the bottle well, and spray about 5cm through the air outlet to the heat sink.
3. After spraying, wait for 15 minutes, and then run the air-conditioning refrigeration program for 15-30 minutes normally, and the sewage will be automatically discharged with the drain pipe.
Note: Please insert the tube tightly when using, so as not to fall off when spraying.
Eight, secondary cleaning
At the beginning of summer and winter every year, two major cleanings are carried out to achieve the purpose of sterilization, disinfection and purification. Cleaning the air conditioner, removing the growth of microorganisms, and eliminating the root cause of bacteria, so that the conditioned air sent by the fan meets the air hygiene standards, and it can also avoid the symptoms of allergies or respiratory tract infections in some people who are prone to allergies.
