Application of plasma air purification technology in central
Author: Li Deng environmental protection
It is well known that the development of the HVAC industry, technology applications, trends and directions, through the technological innovation and combination of improving air quality, set the comparison and analysis of various existing air purification technologies.
Second, human beings have received unprecedented material wealth and enjoyment, and they have also suffered from the unsustainable "sick building syndrome". No matter whether HVAC equipment R&D and design personnel continue to consider energy-saving and environmental protection, HVAC technology will be solved. It is not only the problem of cold and warm in the low-level local closed space, but also the improvement of the overall quality of air, from air humidity, air cleanliness, air quality (that is, solving air pollution), and the use of HVAC equipment, comfort, etc. Consider several aspects of the development direction of HVAC industry technology. During the SARS period, the state explicitly stipulated that non-independent operation of air-conditioning was not available. The micro-organisms in the central air-conditioning pipelines multiplied, especially the detection rate of deadly Legionella was over 50%, and the number of deaths of Legionella worldwide reached 3.6 million per year. According to a report by the Association in 1992, the annual loss caused by sick building syndrome was as high as 60 billion U.S. dollars due to the low quality of HVAC air. In 2002, a research team of a birth defects monitoring project in the United States passed 9,000 new students. A follow-up study found that women inhaled contaminated air during pregnancy, and that infants born in the future are three times more likely to develop heart disease than those born to pregnant women who breathe fresh air. In 2006, China Indoor Decoration Association Indoor Environmental Monitoring Center issued a warning that indoor environmental pollution is the main cause of childhood leukemia. 90% of children with leukemia have been renovated within half a year before the diagnosis, and there is no effective air purification treatment. The above series of reports and data clearly show that the air quality in buildings directly affects the basic needs of human health and even survival as an important development direction.
Plasma air purification technology will inevitably become the future technology of the central air conditioning system and the application of public places:
First, the history of the HVAC industry can be traced back to ancient times when humans have not yet acquired civilization. With the further development of HVAC industry technology, the printing and publishing industry in the United States in the early 20th century was seriously affected by the air humidity of the workshop and the temperature. Deeply troubled, developed the world's first air conditioning system (referred to as air conditioning), the first to develop air-cooled chiller technology and later large-scale applications, and the HVAC industry has gradually become indispensable now and in the future An important industry.
Third, the air purification technology currently used in the HVAC industry; there are three main types of air quality pollutants: 1. Chemical harmful substances in the air, such as benzene, toluene and formaldehyde in interior decoration; 2. In the air Microorganisms such as bacterial viruses, such as influenza virus, Legionella, and tuberculosis viruses; 3. Fine particles suspended in the air, such as soot, microbial remains, and industrial dust.
Currently commonly used can be divided into three types of air purification technology:
1, that is, filtration adsorption, physical and chemical sterilization and electrostatic dust collection technology;
