Under the influence of an applied electric field, fan coil air cleaning devices offer a large number of portable electronic bombardment contaminant molecules can be generated by the discharge medium to ionization, dissociation and excitation, and have led to a series of complex physical and chemical reactions, make complex molecules into simple small molecule contaminants security matter, or to toxic and hazardous substances into non-toxic or low toxicity harmful substances, so that the degradation to remove contaminants. Because even after the ionization electron energy generated in 10ev, proper control of the reaction can be achieved under the premise of generally difficult or slow the chemical reaction becomes very fast. Ion oxygen use a special high-energy beam of ultraviolet radiation and ozone UV low-temperature plasma generated by treatment of odorous gases, changing malodorous gases. As environmental pollution treatment field has a strong latent advantage of a high-tech, plasma has been highly concerned about the industry at home and abroad related disciplines. Low-temperature plasma: Corolla dielectric barrier discharge technology, the air humidity is less than 40%, the ion concentration is greater than 1 meter 1,600,000, the use of large capacity frequency voltage corona discharge technology, fan coil units, air-purifying price, to change the traditional block structure greatly reduce equipment costs, the use of dual media discharge, especially the number of positive ions greatly improved oxidation was significantly enhanced. Lightwave irradiation broader range of products more compact size. Technology statistics, spray 60 square meters which can effectively ensure the purification effect within the area of ??100 square meters; at the same time, the effects of UV irradiation produced by the photocatalyst many factors ultraviolet irradiation angle, irradiation intensity and photocatalyst surface cleanliness, etc., Shaoguan concentration of fan coil air purification device, produced by the reaction of ozone and other oxidants product is uncontrollable, fan coil units, air-purifying brand, even a small amount of regular length. Photon wave technology works. And may be increased or decreased by the irradiation power to achieve quantization control of ozone and other oxidants products. Photocatalyst technology is different with the general principles of nanophotonic wave technology is the use of a particular spectrum of light waves, molecules of oxygen in the air ionization, collision, combined, through photoelectrochemical produce ozone, hydrogen peroxide, and hydroxyl radical anion nano photon wave technology inventions began in the United States in the 21st century, and quickly and is widely used in the field of water and air purification, deodorization, sterilization, disinfection, bleaching, degradation of COD and so on. Ozone, hydrogen peroxide and hydroxyl radicals have a strong redox, with sterilization and degradation of VOC role. It is the biggest difference from the usual photocatalyst technology are: the usual photocatalyst technology is contactless, pollution or contamination of the air required for the full and photocatalyst (usually TiO2 and mixtures thereof) full access to adequate response, in order to purify the surface of photocatalyst effect.
