The present invention provides an air conditioning system that can appropriately adjust humidity. The air conditioning system is an air conditioning system that comprises a plurality of indoor units that jointly air conditions a same space, comprising a first indoor unit and a second indoor unit. The first indoor unit comprises a first indoor heat exchanger that adjusts the temperature in the space. The second indoor unit comprises a second indoor heat exchanger and a humidifying element. The second indoor heat exchanger adjusts the temperature in the space. The humidifying element adjusts the humidity in the space. Further, the air conditioning system, during humidity adjustment, adjusts the humidity in the space by the humidifying element with greater priority than adjusting the temperature in the space by the second indoor heat exchanger.
