VEHICLE AIR CONDITIONING SYSTEM

A vehicle air conditioning system includes: a dehumidifying device; a power source; an inflow pipe for allowing air from a vehicle interior or a vehicle exterior to flow into the dehumidifying device; a first outflow pipe for returning the air that has been dehumidified by the dehumidifying device to the vehicle interior; a second outflow pipe through which the air containing moisture released by a regeneration process of the dehumidifying device is circulated; and a switching valve provided at a branch portion between the first outflow pipe and the second outflow pipe, the switching valve being capable of switching the flow of the air to the first outflow pipe or the second outflow pipe. A separator capable of separating moisture contained in the air by centrifugation is provided in the second outflow pipe. The second outflow pipe merges with the first outflow pipe on a downstream side of the separator.
