Wei, a central air conditioning system, air cleaning devices eliminate virus study bacteria 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-fan coil air purification and disinfection systems tube factory air disinfection, to enable it to design complex integrated high voltage electrostatic through clever structure, 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 , fill no uniform standards and testing methods for engineering application blank disinfection device research program. 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 fan coil air sterilizer prices, 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, maintenance, maintenance convenient: With semiconductor fan coil air sterilizers, contaminated product components can be washed with water only; 2, field first aid: for combat troops and wounded after the earthquake emergency surgery; 3, luxury: automatic, timing, manual three disinfection mode arbitrary choice; 4, intelligent control: use of gas, particles, oxygen, and other sensing technology hospital fan coil air disinfection, to achieve automatic control of startup and shutdown; 5, energy saving and environmental protection: using cleaning methods can be realized for recovering exhaust gas treatment thereof; 6, broad-spectrum sterilization: to airborne bacteria, fungi, viruses and bacteria Escherichia dry; 7, efficient purification: more than 0.1μm dust particles in the air removal ≥99.00% ; 8, efficient sterilization: to achieve air natural bacteria kill rate ≥99.00%; product performance and characteristics: the first invention of the semiconductor center abroad conditioned air disinfection purification, won the national utility model patents and patents.
