Wei, a central air conditioning disinfection purification devices at the train stations and other places. Select rail more and more people, the total number of passengers also continue to create miracles. But with the increase in the number of passengers, subway cars gradually turbid natural air ventilation insufficient electrostatic dust removal equipment central air conditioning prices, 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, crowded, central air mobility electrostatic dust removal equipment Which is good, can lead to the spread of disease, its impact on human health than others transport more serious. Subway vehicle operation frequent braking and wind effects Pistons in the air is full of fine particulate matter, subway cars air of respirable particulate matter far more than the powder content of the national standard, in addition to central air-conditioning equipment electrostatic dust, formaldehyde, total number of bacteria, viruses and other microorganisms 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! Dongguan City Environmental Technology Co., a photocatalyst air purification system with air-conditioning photocatalyst air purification device is designed for supporting the design of the central air conditioning is widely used in fan coil units, air conditioning units, the return air duct and other locations. Central air conditioning electronic air purification device in accordance with <>, composite sterilization, sterilization triple electronic purification technology, is the latest of an air-terminal air handling systems. Electronic air cleaning device with air-conditioning electronic air cleaner is designed for central air conditioning equipment supporting the design, widely used in fan coil units, air conditioning units, the return air duct and other locations. . The central air conditioning photocatalyst air purification device in accordance with <> research produced, set sterilization, deodorization, decomposition of formaldehyde in one of the central air-conditioning electrostatic dust removal equipment design, is one of the central air purification equipment is the best. Has dust, sterilization, decomposition of toxic gases eliminate odors, release positive / negative ions and other functions. Power and air-conditioning fan linkage control, convenient and flexible. Power and air-conditioning fan linkage control, switch and indicator shows air purifier running. China is currently the most advanced purification sterilization effect one of the best central air purification equipment. At the same time the central air conditioning, cleaning costs can be saved and remove odors such as renovation costs of air pollution, with dust, sterilization, decomposition of toxic gases and deodorization function.
