1. The electrostatic air purification systems under the action of high voltage power supply, strong electrostatic field generating large number of charged ions. By air, the solid particles are adsorbed electrode of opposite polarity, bacteria, fungi, viruses and other microorganisms were electrolysis charring and death. Electrostatic air purification systems Schematic as follows: 1) flat electrical wire technique is to form a strong electrostatic field use electrical wire, so that the dust in the first stage of the wire under high energy from the electric field ionization (operating voltage greater than 8000V), the second phase of the charged particles are adsorbed in the electrostatic precipitator plates (operating voltage greater than 4000V). Silk long time tablet applications Electrostatic Precipitator technology, mature technology, air handling field at home and abroad widely used. Can effectively reduce the transport of fresh air needed to achieve the purpose of energy saving central air-conditioning air purification devices, the real solution to the current modern architecture respiratory system with air-conditioning "detoxification mouth" setback, reduce the "sick building syndrome" crowd in Central Air Conditioning purification device customization, but also a fresh and clean earth living space. Photocatalytic air purification disinfection sterilization technology we use is the industry's most recognized to improve their predecessors, highest-tech air purification technology central air conditioning, air-purifying price to achieve sterilization sterilization air purification technology system transplanted to the center from the true sense integrated air conditioning system. Wei, a central air conditioner supporting air sterilization purification device can play to prevent chronic and sudden spread of air pollution, while the center can save the expense central air conditioning cleaning air cleaning devices designed each year to reduce air pollution decoration odor management costs, progress place of utilization of banks, office buildings, research buildings, hotels, restaurants, convention center, stadiums, airports and villas. Dongguan City Environmental Technology Co., one using the most senior of purification technology to improve the introduction of DCHB series central air conditioning air sterilization purifier is central air conditioning, heating, fan coil units for air purification equipment for sterilization, which uses physical adsorption and photocatalytic decomposition collaborative technology, dust, odor, decomposition of harmful organic compounds (such as formaldehyde, benzene, TVOC, etc.), kill microorganisms bacteria, viruses and other multiple effects, settling dust, eliminate odors, to make the air fresh, can solve air quality problems within the central air conditioning.
