Model: VBY-H Wei, a central air-conditioning air purification and disinfection unit in accordance with <>, the use of a semiconductor Wei Wei disinfection purification technology and a dual light wave reactor technology sterilization latest an air purifier equipments. The aircraft use double sterilization air purification, attract air pollutants solve indoor air quality problems. It is currently China's leading central air purification equipment. First, Wei a central air-conditioning, plasma air purification profile 1, primary filter to prevent small animals and large particles into the air conditioning. 2, electrostatic dust filter dust collector is the use of pre-charge extremely nonuniform electric field, forming a corona discharge, a large number of electrons and positive ions contained in the electric field gradient, and particles in the air inelastic collision, thereby adhering In the above, making charged particles. Under an applied electric field force, charged particles migrate to the collecting electrode, the dust finally deposited on the pole. 3, plasma catalytic filter in the process of generating plasma sterilizers ducted air quotes, high-frequency discharge produces instant high-energy, open some harmful gas molecules bond, in particular the removal of air pollutants in a very Even completely decomposed within a short period of time. 4, negative ions, increase air vitamins. Wei eliminate the virus means a central air conditioning system research in clean air germs are Shanghai Jiaotong University organized an interdisciplinary central air conditioning system cleaning off the virus germs means of research projects, aimed to develop a new multi-filter disinfection system, so The ingenious structural design through complex integrated high-voltage electrostatic, ultraviolet, silver and photocatalysts filtration technology, and the construction of a central air conditioning system disinfection, in addition to virus detection platform processing apparatus and method for testing ducted air sterilizers, filled domestic engineering applications sterilization device is not blank unified research program standards and testing methods. In a short time, the task urgent circumstances, to address the public on the central air conditioning may become confused atypical pneumonia (SARS) virus spreading tool dismayed hospital duct air disinfection, especially to prevent the hospital contain pathogenic microorganisms contaminated air through the air conditioning system expansion of the population, medical personnel infection, develop a set of high disinfection efficiency, no secondary pollution, small device resistance, easy installation and maintenance, high-tech air-cleaning device is suitable for applications in HVAC easy to operate with a special significance and research value. The central air conditioning system of the technology used in the construction of buildings, the period of rampant disease health hospital personnel to provide effective protection, and for the stability of the social stability of great significance, the SARS epidemic to the traditional central air-conditioning design questioned lead the red light, the air conditioning industry has been hit hard duct air disinfection company, but also to the central air conditioning provides an opportunity to achieve a healthy upgrade to the original central air-conditioning system transformation brought great business opportunities, the air purification device in SARS mushroomed during and after the growth period is sufficient to illustrate this point.
