Recently, reports of accidents involving home appliances have increased, and air-conditioning fires have the highest frequency. With the arrival of the peak season of air conditioners, the frequency of use of air conditioners has also started to rise sharply. The reporter learned that for air-conditioning products, the most common safety use problem is "fire", then what is the cause of the air-conditioning fire? How can we avoid such a thing?
For air conditioning products, the most common safety use problem is "fire." Reporter Yan Siyu
What are the causes of air conditioning fires?
1. The air conditioner is energized immediately after the power is cut off. At this time, the internal pressure of the compressor is very large, which makes the motor start difficult, and a large current causes the circuit to catch fire.
2. The fan motor temperature rises, causing overheating and short circuit to fire.
3. When installing, connect the air conditioner directly to the power circuit without the safety device.
In addition, improper cleaning of air conditioners is also dangerous.
The experiment tells you that the air conditioner will explode
The experimenter disassembles an air conditioner that needs to be cleaned, and uses medical alcohol to scrub the inside and related parts of the air conditioner case. After the cleaning is completed, the air conditioner is directly reinstalled and the power is tested.
After a few seconds, an explosion occurred in the lower part of the air conditioner, and an explosion occurred in the upper part. A large amount of white smoke was sprayed from the air vent.
Some people will open the panel when cleaning the air conditioner, wipe it with medical alcohol, and disinfect it by the way. If it is wiped off with alcohol, cover the panel and immediately energize it, it may explode.
Researcher at the School of Physical Science and Engineering of Guangxi University said: The ignition point of alcohol is extremely low. If the air conditioner is wiped with alcohol immediately, it will cause a little spark on the board. These sparks can directly ignite alcohol. When cleaning the air conditioner, if alcohol is used, it must be waited for half a day after wiping, so that the alcohol is completely volatilized before use, so that there will be no air conditioning explosion.
Correct air conditioning cleaning method
Wall-mounted air conditioner cleaning
1. Disconnect the power supply, open the air conditioner panel, open the cover, and wipe the exposed case with a damp cloth.
2. Slowly take out the air conditioning filter. When there is less dust, wash it with water or vacuum it.
3. When the ash is serious, soak it in water containing neutral detergent for 10 to 15 minutes. After washing, please dry it and dry it in a cool place. Do not heat or dry it at high temperature.
4. After installing the filter, close the panel and let it stand for 10 minutes, then turn on the air conditioner and adjust the air volume and heating capacity to the maximum. Keep the air conditioner on for 30 minutes.
Cabinet air conditioner cleaning
1. Turn off the power and use a screwdriver to turn off the screws on both sides of the fuselage panel to open the panel.
2. Remove the filter.
3. Use a shower to pour water from the back of the filter to clean the dust; after cleaning, dry the back.
4. After drying, reinstall the filter and close the top cover.
