Supply fan coil private / return air purification and disinfection equipment type / blower type purifier equipments / fan coil air purification device / air duct cleaning and disinfection of equipment by double ionization semiconductor devices dust, light and medium-contact oxidation catalytic sterilization, to achieve air disinfection, purification. Nanomaterials itself can not afford to change, Hebei subway air purification device, but can promote chemical reactions. Nanophotonic wave light catalytic purification technology as an important branch of art, can not be compared with the traditional strengths of photocatalyst technology has been widely used in air purification project. This article explains the principles of photocatalytic purification technology, different general photocatalyst technology and photonic wave technology were compared, specifically addressed the characteristics of the photon wave technology. Theoretically valid for very long, low maintenance costs. With engineering practice, summed up the photon wave in Engineering and advantage. People living along the level of progress, the air quality is increasingly becoming an important measure scale air-conditioning effect. Photocatalytic other material purification technology in recent years the rise of a cutting-edge high-tech purification technology, which through O2 and H2O in the air in contact with the organic contaminants (VOC) is converted to CO2, H2O and the like. The Photocatalyst loaded on the activated carbon honeycomb surface, use of activated carbon adsorption function to enrich pollutants decompose pollutants by photocatalysis activated carbon adsorption, air purification devices metro price to achieve physical adsorption and photocatalysis synergies, how much money subway air purification equipment, greatly improving the photocatalytic efficiency. To achieve energy saving in daily consumption of air conditioning costs 6000 yuan for example, the new wind power costs about 1,300 yuan, after the installation of the air cleaning device, can be reduced by 50% of the fresh air transport, the subway air purification device manufacturers, their day can save electricity by 600 yuan terms, the annual electricity savings of about 20 million. According to the current central air conditioning cleaning industry's fee scale (usually 24 yuan / m2, according to air conditioning pipe wall expansion to calculate the area), 2000 ~ 4000m2 cleaning costs at least once at about 5 to 10 million. Ministry of Health designate the central air conditioning to be cleaned once a year. Extend the cleaning cycle air-conditioning system, reducing maintenance costs. At the same cellular structure not only greatly increased the surface area support, to extend the residence time of contaminants resistance photocatalytic online, but also to purify the network is greatly reduced. Install this purification device owners can save half the cleaning costs. Subway air purification devices offer _V1 / Wei in Anhui _ a metro air purification device provided by the Dongguan City-an Environmental Technology Limited.
