Wei, a central air conditioning disinfection purification devices at the train stations and other places. Select rail more and more people central air electrostatic dust removal equipment price, total passenger traffic also continue to create miracles. But with the increase in the number of passengers, subway cars gradually turbid inadequate air ventilation, air exchange with the outside world can only be carried out by the station entrances and limited tunnel air shaft. Regulated by the air conditioning system temperature, humidity, air pollution is not conducive diluted because of the lack of sunlight central air electrostatic dust removal equipment design, population density, mobility, can lead to the spread of disease, its impact on human health than other means of transportation more serious. Operation Frequent Wind Effects piston brake and metro vehicles in the air filled with fine particles brand central air electrostatic dust removal equipment, subway cars inhalable powder content of air particulate matter far more than the national standard, in addition, formaldehyde, total number of bacteria, viruses, etc. microbes also far beyond the normal. With the strengthening of environmental awareness, is now more concerned about the environmental quality of life in space, "haze" Chinese people now have become the subject of great concern, ride the subway environment is gradually being taken seriously, especially after the 2003 SARS, the State Council " public health regulations, "the Ministry of Health and Health Governor Fa [2006] No. 58 the text" public places, central air conditioning ventilation system health standards "in all of central air conditioning systems, air-purifying proposed requirements. But environmental scientists believe that the formation of haze after a long period of accumulation, and want to eliminate haze also need some time. Since short time can not change the environment, we can do is try to improve indoor air quality, we recommend the use of a central air-wei disinfection purification devices! Central air conditioning, air-purifying technology used broadly divided into the following categories, they have their own strengths, and with advances in technology continue to improve. 3. UV lamp UV antivirus technology is the use of UV lamps emit UV-C to kill bacteria, viruses and other microorganisms, or loss of activity, can be used for air, water and surface disinfection. Its economy is high, it has been widely used in water treatment, food and beverage, wine, and other fields, as well as hospitals and other places. However, the use of UV technology in the AHU, because the air flow rate is too high (usually 2-3 m3 / s) can not achieve the desired purification effect, and the tube surface can easily be covered with dust and useless. Therefore, central air-conditioning equipment electrostatic dust, dust in the larger subway cars UV lamp technology is not applicable. Wei, a VBK-G-duct air purification device today we will stop here, there will be follow-up after another supplement, please continue to care a great environment!
