PROBLEM TO BE SOLVED: To send sterilized cooling air into each room and sterilize bacteria into the condition near to a roughly asepsis, by arranging a sterilizing means in the vicinity of the duct entrance inside a duct. SOLUTION: Cold air is sent into each room from a duct exit 39 via a duct 30 by an air conditioner 20 by operating the air conditioner 20. At this time, at the entrance 31 of a duct, the bacteria in the air from an air conditioner 20 are sterilized by ultraviolet ray lamps 11 and 12. Furthermore, the ultraviolet ray lamps 11 and 12 are arranged two sets each face to face. Hereby, as against the case of only one set in which the place where an infrared ray is not applied remains around around an ultraviolet ray sterilizing lamp mount 15 or around the sterilizing lamp 11 and the air not sterilized by it flows to the duct exit 39, in this system such trouble is prevented, and the sterilization efficiency is raised, and the condition of roughly asepsis becomes possible. |
