摘要：Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses shortwavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, A modular germicidal light grid system is used inside an air conditioning unit that has a section through which a stream of air is passed. The system comprises of one lamp assembly and one linear germicidal light Source.UVGI systems use much more concentrated levels of ultraviolet energy than are found in sunlight. The kill rate of pathogens and other microorganisms using UVGI depends on several factors, including UVGI intensity, the number of microorganisms present, and the amount of time the microorganisms are present in the UVGI Zone, or dwell time. Generally, kill rate increases as the UVGI.
