1. UV disinfection technology

UV disinfection is one of the effective sterilization methods. It has been widely used in the field of water treatment as early as the beginning of the last century. However, the application of UV disinfection for flowing gas has gone through a complicated process.

       The first experiment of UV disinfection of air was carried out in the 1920s. The experimental results at that time showed that the disinfection effect of this method was feasible. Since 1936, ultraviolet disinfection technology has been used in operating rooms. In 1937, it was first used in schools to reduce the spread of rubella and achieved satisfactory success. At the same time Riley and O'Grady began to study the application of ultraviolet radiation to disinfect the air containing tuberculosis bacteria discharged from the hospital.

        According to different biological effects, ultraviolet light can be divided into four parts according to wavelength: UV-A, UV-B, and UV-C. UV-C wavelength range is 100-290nm, also known as disinfection ultraviolet.

         2. Ultraviolet disinfection of pipelines

         When installing UV disinfection equipment in the air duct, it is generally placed on the downstream section of the mixing box in the AHU and on the upstream section of the fan coil. In the case of a separate UV lamp installed in the air duct, the "Disinfection Technical Specification" stipulates that the radiation dose should reach 10,000 uWs/cm² when killing general bacterial propagules; when killing bacterial spores, it should reach 100,000 uWs/cm² in the disinfection target When the microorganisms are unknown, the radiation dose should not be less than 100,000 uWs/cm².

          People's attention to the spread of infectious diseases and biological and chemical weapon attacks will affect the design of the air-conditioning system and the entire building. The transition from energy-saving buildings, green buildings, ecological buildings, healthy buildings to immune buildings is a challenge to the building's air-conditioning system. An important part of the immune design of the central air-conditioning system is the choice of reasonable disinfection and sterilization methods.

          UV disinfection has been widely used in industries such as hospital wards and catering. The uv lamp of Lightbest uses ultraviolet rays 254nm to kill bacteria. This kind of ultraviolet rays can kill many bacteria. The air duct sterilization component is a kind of ultraviolet fixing device, which is mainly used in the air duct system and uses ultraviolet light to remove The bacteria and viruses in the pipeline create a better and healthier environment.

           It is widely used in commercial and civil UV systems to destroy the activity of microorganisms and sterilize air, water and surface of objects one by one. Ultraviolet rays can reduce or remove bacteria such as fungi, viruses, bacteria, fungi and mold spores in the air of homes, offices and commercial buildings, thereby ensuring a higher quality indoor air.
