As an important indicator of a green hospital, '' ¨ energy saving has become the center of power-hungry air conditioning research focus. These places are: the cleansing operation, delivery rooms, ICU ward, neonatal ward, hemodialysis, blood wards, supply room, with central, DSA room, reproductive center, the burn ward, biological and animal laboratory, outlet air purification devices offer, and purification requirements vary in each place. Different functions of the department and to the central air conditioning requirements for the hospital, specially designed set of integrated systems for the hospital actually needs solutions. Hospital indoor clean air conditioning system solutions along with countries inside the hospital infection control, prevention work more squarely Hebei outlet air purification device for hospital air environment increasingly demands progress. Dedicated fan coil supply / return air purification and disinfection equipment type / blower type purifier equipments / fan coil air purification device / air duct cleaning and disinfection of equipment along 12th Five Year Plan is increasingly advancing, people's livelihood, '' Green Hospital ' 'construction has become an inevitable trend in the national hospital building. According to the national "Disinfection technical specifications", the scope of Class I environmental requirements more widely, on many occasions inside the hospital have raised the clean air requirements. Hospital with matching, central air conditioning system installed inside the purifier, central air conditioning light hydrogen ion purifier can be installed: the air conditioning vent, return air, fan coil units, air-conditioning boxes. Supply fan coil private / return air purification and disinfection equipment type / blower type purifier equipments / fan coil air purification device / air duct cleaning and disinfection of equipment by double ionization semiconductor devices dust, light and medium-contact oxidation catalytic sterilization, to achieve air disinfection, purification. Nanomaterials can not afford to change itself, it can promote chemical reactions. Nanophotonic wave light catalytic purification technology as an important branch of art, can not be compared with the traditional strengths of photocatalyst technology has been widely used in air purification project. This article explains the principles of photocatalytic purification technology, air purification device outlet prices, different from the ordinary photocatalyst technology and photon wave technology were compared, outlet air purification device specifications, specifically addressed the characteristics of the photon wave technology. Theoretically valid for very long, low maintenance costs. With engineering practice, summed up the photon wave in Engineering and advantage. People living along the level of progress, the air quality is increasingly becoming an important measure scale air-conditioning effect. Photocatalytic other material purification technology in recent years the rise of a cutting-edge high-tech purification technology, which through O2 and H2O in the air in contact with the organic contaminants (VOC) is converted to CO2, H2O and the like. Outlet air purification equipment manufacturer, Wei, a Jiangxi outlet air cleaning device is provided by a Dongguan City Environmental Technology Limited. Dongguan City-a Environmental Technology Limited (www.v-1.com.cn) (www.v1xdj.com) Dongguan, Guangdong, a leader in environmental protection products processing, over the years, the company is implementing the scientific management, innovation and development, honesty and trustworthiness The guidelines, the maximum meet customer needs. In V1 / Wei a leadership with the staff warmly welcome all inquiries negotiations to create the V1 / Wei a better future.
