In addition, it is possible to realize a large-capacity outside air processing system 1 in which all the outside air processing units 20a to 20d operate as a single unit. In addition, even when the RA temperature / humidity sensors 9b to 9d provided in the outside air processing units 20b to 20d are out of order, the outside air processing units 20a to 20d are provided in the outside air processing unit 20a in the operation operation.
