PROBLEM TO BE SOLVED: To provide a vertical laminar flow-type bioclean room and a relay unit capable of reducing costs by dispensing with large-scaled repair work and shortening work periods, having high degree of freedom in layout, and keeping a bioclean environment while saving energy.SOLUTION: A vertical laminar flow-type bioclean room is provided with an air conditioner unit 2 disposed in a ceiling of a patients room and supplying air downward from a ceiling surface, a relay unit (T1, etc.) disposed under a patient bed to suck the surrounding air and exhausting the air in the transverse direction, and a duct panel 3 disposed along a wall of the patients room and having a suction port 3a at a lower section. The air conditioner unit 2 has a HEPA filter 22 at an air supply side of an air conditioner 20, and a return air chamber 21 communicated with the outside air and the duct panel 3 at a suction side. The air sterilized and purified by being passed through the HEPA filter, is supplied as descend laminar flow toward the bed from the ceiling surface, and the surrounding air under the bed is sucked from the suction opening and returned to the return air chamber, by making the air conditioner unit 2 and the relay unit cooperate with each other. |
