PURPOSE:To reduce an installation cost and an operation cost for a cooling and ventilating device for a bus by a method wherein a ventilating mechanism for air in the car, a heat-exchanger unit for cooling and a fan for forcible diffusion are integralized into a small size and a necessary number thereof are distributed and arranged at a ceiling of a passenger room. CONSTITUTION:A necessary number of cooling and ventilating devices 1 are installed at a ceiling R of a bus while a compressor, a condensor and the like necessary for compressing and cooling a cooling medium are installed in an engine room. Respective cooling and ventilating devices 1 are equipped with outer air sucking ports 2 at fore portions thereof and inner air discharging ports 3 at aft portions thereof while top portions thereof are covered with detachable inspection lids 4. A cross-flow fan 5 for forcible diffusion, a heat-exchanger unit 8 for room-cooling and the like are accommodated within the device. Further, the sucking port 2 and the discharging port 3 are provided with shutters 9, 10 which are enabled to be opened or closed independently by geared motors 15, 16 through cranks 13, 14 or the like.
