subject: Beware Of Inappropriate Long-closed Air-conditioned Room Germs - Air Conditioning, Central Air [print this page] As the weather gradually changed, people have gradually started to use air conditioning. Experts advise, summer is the season of high frequency air-conditioning, air conditioning disease is the high season. According to reports, air conditioners contain bacteria, molds, mites and other substances make people sick, one of the "Legionella" caused by the "Legion of experts around the world caused by neck in recent years, great attention, although the" neck in the Army is not in Shanghai generally, only a few cases a year, but should still pay attention to prevention.
Air conditioning evaporator is a breeding ground for bacteria
Air conditioning in use one year after the poor cooling effect occurs, the wind dropped and so on. Prolonged stay in air-conditioned room were prone to fatigue, decreased immunity and other symptoms. Experts believe that these phenomena are due to large air conditioning evaporator and condenser on the accumulation of bacteria, dust, smoke and oil and gas result.
Air Conditioner send cold or hot air at the same time, indoor dust, bacteria will be a lot of suction, the general public as long as the annual cleaning air conditioning filters can be peace of mind, but the problem is a large air filters can only block the dust, 80% of the bacteria into the air conditioning, air conditioning evaporator produces water vapor as heat exchanging, humidity close to 100%, after the shutdown will continue for a long time. This relative humidity conditions for bacteria to multiply multiply this indoor bacteria density rising to reach a certain number, people would be caused by glass
Harmful bacteria in the most prominent proliferation of Legionella suitable breeding environment temperature 20 ~ 35 , relative humidity 75% to 100% in 100% humidity, temperature 31 -36 when long-term survival. Home air conditioning evaporator for Legionella thrives precisely provide suitable environment.
Air conditioning room not long-term closure
Accumulation of air pollutants
mainly bacteria, pathogens, particulate matter, fungi, mites, carbon monoxide, volatile organic compounds, because the room temperature appropriate, pathogens in the air conditioning inside the large population, with the air conditioning cycle, is sent to every corner of the room. Prolonged stay in air-conditioned room who would feel dizzy, fatigue, weakened immunity and may even suffer from serious respiratory and other diseases, namely, "air conditioning neck.
Relatively closed because air-conditioned rooms, indoor temperature and humidity are suitable for pathogenic microorganisms, especially fungal growth and reproduction. If irregular or never clean condition with dust filters, ventilation duct system, air conditioning an open line of germs and dust Dust will blow out one after the deposition in respiratory tract inhalation or skin is attached to the body, resulting in itchy skin, nasal congestion, sneezing, asthma and other discomfort. Many people also believe that as long as cleaning the filter cover, air conditioning even washed up. In fact, cleaning air conditioning heat exchangers are mainly washing (ie, evaporator and condenser), preferably by a professional technical personnel to special equipment, special air cleaner for cleaning. The only way to achieve the objective of eradication of pathogens. Also, after cleaning the air conditioning, refrigeration better, but also reduce air pollution.
Air conditioning products could lead to bacterial pneumonia
Bacteria accumulate within the air conditioning to a certain extent easy to trigger air-conditioning pneumonia. Mainly spread through the air by inhalation, the human body. Legionnaires disease is high in autumn of the season, especially in the modern equipped with air-conditioned environment. Among them, "Legionella" pneumonia latency ranging from 2 to 20 days. Legionella pneumonia since the beginning of symptoms and the general is no different, a bit like cold, fever, cough, chest pain followed by difficulty in breathing. But even more dangerous than ordinary pneumonia is Legionella also carried out against the nervous system of patients, patients appear blurred vision, lethargy and so on. Legionella bacteria also have damage to the digestive system, patients will experience nausea, vomiting, diarrhea and other symptoms. In addition, Legionella is also against the kidneys, patients with hematuria will appear.
Elderly people: air conditioning pneumonia in high risk groups
Air conditioning in the accumulation of household mold, mites may trigger asthma, has been sensitivity to people's attention, as children's allergies, which is why, indoor air pollution is often the object of protection against children or people with asthma.
