PROBLEM TO BE SOLVED: To provide an air-conditioning system for an operation room, even when a traveling device of a fluoroscope reciprocates over traveling rails laid on a ceiling, capable of supplying a clean and temperature-conditioned air immediately beneath a moving passage of the traveling device and continuously supplying the clean and temperature-conditioned air to a surgical bed and an entire peripheral area thereof.SOLUTION: In an air-conditioning system 50A of an operation room 51, a controller 69 includes: first aeration stop means that stops the supply of an air from an aeration unit 65A-65H of first to eighth aeration units 65A-65H to which a traveling device 63 approaches, on the basis of a proximity signal from first to eighth proximity sensors 68A-68H and first aeration start means that starts the supply of air from the aeration unit 65A-65H of the first-eighth aeration units 65A-65H from which the traveling device 63 is separated, on the basis of a separation signal from the first to eighth proximal sensors 68A-68H.
