吹空调也会“致命”！ 吹空调也会“致命”！ Blowing air conditioning will also be fatal!
2021年06月29日 更新 | 共1991人阅读
This year's sultry weather has come a bit unexpected, many people have turned on air conditioning "to continue life.". However, air conditioning, which has not been used for a long time, can be a bacterial transmitter, and it can cause serious consequences if you don't take care of it.
On June 3, a 42 year old man in Ningxiang, Hunan Province drove a car that was not opened in two months and went out with air conditioning. Unexpectedly, he had high fever and dyspnea. He was diagnosed with Legionella pneumonia and was admitted to ICU ward.
On May 20, 37 year old man in Yichang, Hubei, blew air conditioning into ICU and stayed in danger for a week.
On May 13, a man in Changsha, Hunan Province, had high fever and dyspnea when he was blowing air conditioning at home. He was diagnosed with Legionella pneumonia after he was hospitalized. High temperature and humidity weather is the best for germs to breed, and they may have grown arbitrarily in air conditioning. What can I do to kill these dangerous bacteria《 Life times interviews experts and gives you a life manual in an air-conditioned room.

The air conditioner without washing = the bacterial injector is not opened to see how dirty it is: besides the dust visible to the naked eye, there are many invisible bacteria, fungi and mites... The air conditioning sanitation survey published by the center for disease prevention and control of China shows that in the detection of dust accumulation and dust accumulation bacteria content in air-conditioning system air-conditioning system in more than 60 cities, The air-conditioning air ducts with serious pollution accounted for 47.11%, the medium pollution accounted for 46.17%, and the qualified air-conditioning air ducts accounted for only 6.12%. After the investigation of domestic air conditioning in Shanghai, Beijing and Shenzhen, the indoor environment and health branch of the Chinese society of Environmental Sciences found that 88% of the air conditioning fins in China exceeded the standard, 84% of the air-conditioning fins were over standard, and the highest bacteria detected on the air-conditioning fins could reach 91259 per square centimeter, The number of bacteria exceeding the standard (the total number of bacteria per square centimeter is less than 100) is nearly 40 times, and the most serious one is nearly 100 times. Among these air conditioning pollutants, there are more bacteria in summer and more fungi in winter. Direct start-up and use of an air conditioner without cleaning is equivalent to opening a bacterial injector, blowing pathogenic bacteria in the air conditioner to every corner of the room, increasing the risk of respiratory diseases such as pneumonia, tracheitis, asthma, etc.
Hand hands teach you to wash air conditioning
To breathe clean air, the air conditioning should be thoroughly cleaned and sterilized before the first time it is started.
Air conditioning cleaning method
Housing and screen
Cleaning and drying
First open the shell of air conditioner, remove the filter screen in the air conditioner, place the filter screen in warm water and soak it, and then clean it to dry, and then install the filter screen back into the air conditioner.
Heat sink
Disinfection of disinfectant
Air conditioning radiator is not removable, only wipe with wet cloth, brush cleaning is useless, and it is also easy to damage the heat sink. The normal air conditioning disinfectant should be used for cleaning. When selecting, the "certificate number of disinfection products of the Ministry of health" should be approved, so that the sterilization and disinfection effect can be guaranteed.
Evaporator and condenser
Spray cleaner
Can buy professional cleaning agent, shake well, spray on the inlet side of evaporator, then wipe gently with a cloth, and then turn on the air conditioning after the evaporator is dried. When cleaning condenser, only spray cleaning agent near the exhaust port of compressor and dry it.
Tips for cleaning: when using frequently, clean and disinfect once a month. You can also ask professional air conditioning maintenance personnel to clean them on the door. Some intelligent air conditioning can "bath" themselves, and eliminate the radiator dust. When selecting air conditioning, you can choose this new product. Drivers should also pay attention to the air conditioning of the car. It is better to sterilize and deodorize the air conditioning system when they are used for the first time in the new season, and replace the filter element once every half a year.
Clean air conditioning can hurt you, too
Even if it is clean air conditioning, improper use will bring about physical discomfort.
1. Allergic reaction
Some people have a very sensitive nose to cold and hot air. When cold and hot air enters the nasal cavity alternately, they may cause allergic symptoms, such as runny, sneezing, nasal congestion, dizziness and headache.
2. Pain induced
Under the condition of low temperature and humidity, it is easy to induce pain, which has a great influence on the damaged or joint degeneration.
3. Xerophthalmia
Dry, dirty air can cause dry eyes discomfort, serious even can induce dry eye disease.
4. Cardiovascular injury
The temperature difference between the indoor and outdoor is too large, which is very unfavorable for cardiovascular patients. Low temperature environment can stimulate the body, make blood vessels contract, aggravate the burden of the patients' heart, and induce cardiovascular disease. The air conditioning room is not ventilated for a long time, and oxygen content may decrease, which may aggravate the degree of myocardial ischemia and hypoxia in patients with coronary heart disease, resulting in chest depression, dizziness, angina and other symptoms.
Four steps for both cool and healthy
In the summer of dull and hot, we can only stay in the air-conditioning room safely, cool and healthy.
1. The third high school patients enter the door "slowly"
First, stay indoors for 3-5 minutes, then walk to the outdoor shade for a few minutes and then enter the room. Repeat for 2-3 times. If the body can adapt to indoor low temperature, you can stay in the air conditioning room. This method is especially suitable for middle-aged and elderly people, especially those with high blood pressure and diabetes.
2. Windows open every 2-3 hours
Without natural air convection, the indoor air will become more and more muddy and the oxygen content will decrease. Generally, air conditioning for two or three hours, should open windows for half an hour. It is not suitable to turn on air conditioning all night. At least, it should be adjusted to night mode, as long as it can cool and fall asleep.
3. It is advisable to have room temperature of 25-26 ℃
The temperature difference between indoor and outdoor shall be controlled at 8 ℃ ~10 ℃. Although the high temperature weather above 38 ℃ may occur in summer, the temperature of most of the day is below 35 ℃. It is more suitable to control the room temperature at 26 ℃ and the indoor humidity should be kept at about 60%.
4. Drink more warm water
Air in air conditioning room is dry, which easily causes water loss in the body, and more water is needed. Generally, the drinking water amount of adults in a day should be 1500-1700 ml. in hot weather, it can be increased appropriately. The temperature of water should not be too cold or overheated. The temperature water of 35 ℃ ~ 40 ℃ is the best choice. Air conditioning room is dry, after bath to be timely daubed with moisturizer, if you feel dry eyes can be towel hot compress.
