Abstract
The present application discloses a ceiling-mount air disinfector, i.e., an air disinfection troffer, including: a housing; a first air outlet and a first air inlet respectively near two opposing ends of a side of the housing; a filter covering the first air inlet; a cross flow fan located near the first air outlet, and an air disinfection apparatus disposed in the housing including an ultraviolet disinfection mechanism and an air rectifying chamber, said air rectifying chamber including a plurality of air ducts configured in parallel. In operation, ultraviolet light and air flow are introduced into the air ducts, traveling toward each other along a long side of the air ducts so that maximized air-light interaction time is achieved for the best disinfection efficacy.
