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 structure can be designed by the ingenious 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, to fill the domestic engineering applications disinfection device no uniform standards and testing methods of blank research program. In a short time, the urgent task of Hotel fan coil air sterilizers, central air conditioning to solve the public may become atypical pneumonia (SARS) virus spreading tool confused panic, especially to prevent the hospital contain pathogenic microorganisms contaminated air through air conditioning System expansion of population, health care workers infected, develop a sterilization high efficiency, no secondary pollution, small device resistance, easy installation and maintenance, easy to operate high-tech air-cleaning device is suitable for building air conditioning applications has 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, 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, air purification devices during and after the SARS period springing like growth is sufficient to illustrate this point. 1: Semiconductor, photocatalysis, electrostatic field multiple roles fan coil air sterilizers, enable the bacteria, dust, clean the effect is more reliable, thorough. Third, the combination of places: There are installed central air conditioning in place are suitable, together for: office buildings, hospitals, food shop, beverage shop, airport, library building, science museums, waiting (car) room, gymnasium, fitness facilities, shopping malls, conference room, office space, computer room and other fields 1, combined wide, according to purify the air volume, can be customized. The products use ultraviolet light air nitrogen atoms in the semiconductor electric field emitted excitation nanometer TiO2. 4, a variety of specifications hospitals fan coil air sterilizers, size and flexible, can be installed in different locations, can be customized to meet customer needs in detail. Wei-environment center air purification system features: And air conditioning linkage. According to customer requirements for air volume fan coil air sterilizer price, it can be flexibly combined. 3, for a variety of models supporting the use of air conditioning. A plurality of units can be combined into a tailor-made to deal with the amount of wind. 5, automatic operation, constant high pressure. Shape having a small size, lightweight, simple installation features, without changing the structure of air-conditioning ventilation system. As long as the center of the installation of air conditioning duct on the product on the air conditioning system will be able to conduct a comprehensive sterilization, disinfection, purification. 4: The product has a low air resistance characteristics of the existing air-conditioning ventilation system running a small effect.
