According to the first gang of news, a man in Fuzhou turned on the air conditioner at home that had not been cleaned for half a year, and began to cough after blowing for two days. After coughing for two days, he was delirious and had respiratory failure and was admitted to the hospital ICU. The man was diagnosed with Legionella pneumophila and developed a large area of "white lung" with multiple necrosis and cavities in the lungs.
The doctor said: because the internal environment of the air conditioner is relatively humid, there will be some dust and bacteria in the internal space without using it for a long time, turn on the air conditioner for about 3 hours to ventilate, and the air conditioner is best washed once every 3 months.
Air conditioners can last life or kill
The hottest time of the year is here again. Whenever it is hot, some people always joke that in summer, life is given by air conditioning. However, this air conditioner can continue to live, and it can be fatal if it is not done well.
According to a previous report by CCTV Finance and Economics, many people were admitted to the intensive care unit because of blowing air conditioners. For example, a man in Changsha, Hunan Province, drove a car that had not been driven for two months, and suddenly developed symptoms such as high fever and difficulty breathing, and was rushed to the ICU. Later, it was confirmed that it was a Legionella infection, and doctors suspected that the germs came from the air conditioner in the car. In Yichang, Hubei Province and other places, there are also people who are extremely unwell and sent to the intensive care ward after blowing the air conditioner at home, and then they are all diagnosed with Legionella pneumonia, or related to the use of air conditioners that have not been cleaned for a long time.
How often should an air conditioner be cleaned?
Experts from the Shanghai Center for Disease Control and Prevention said that dust, mites and mold accumulate in the air conditioner at home, and if deep cleaning is not carried out in time, it is easy to cause coughing, asthma, various respiratory diseases and skin diseases as the air supply of the air conditioner flies in the home.
Experts suggest that household air conditioners must be cleaned before they are used every year, especially the cleaning of internal components, which is best left to professionals, while central air conditioners need to be tested regularly and use professional disinfectants to kill germs and mites that breed in the air conditioner.
For families with normal use, it is recommended to wash before summer or winter use; For home or office spaces that use air conditioning 24 hours a day, it is recommended to wash them twice a month.
It's not enough to just remove the filter and rinse it! Professional air conditioning cleaning includes water washing and steam washing, and it is not enough to carry out high-temperature steam cleaning on the inside of the air conditioner, but also focus on the inner machine fins and cross-flow fan blades and other parts that are easy to hide dirt and dirt, and disassemble them and clean them with professional detergents.
How do I clean an air conditioner by myself?
The first step is to turn off the power: this is the easiest step to overlook, and be sure to unplug the air conditioner before cleaning to prevent electric shock.
The second step is to clean the exterior of the air conditioner, scrubbing the casing and exposed parts of the air conditioner with a damp rag. Note: The rag should not be too wet to avoid penetrating into the inside of the air conditioner and corroding the parts.
The third step is to clean the air conditioner filter: the filter device is the core part of the cleaning. Find the clasp on the left and right sides of the air conditioner to open the panel, and gently push it up to open the panel and see the filter. Remove the strainer, rinse the back side (concave) with clean water, and gently scrub with a toothbrush. Rinse and place in a cool place to dry naturally.
Step 4: Clean the evaporator: After the filter is removed, you will see the heat sink of the evaporator, you can choose the household air conditioner cleaning agent for spraying, but be careful not to spray on parts other than the evaporator, so as not to cause a short circuit after starting. After spraying, replace the dried filter and panel and let stand for 10 minutes. At this point, the whole cleaning process is successfully completed.
