1. An air-conditioning system, comprising:
an outside air processing device configured to adjust a temperature and humidity of outside air taken into the outside air processing device and to supply the outside air to a target space; and
an air-conditioning device configured to adjust a temperature of inside air in the target space,
the outside air processing device comprising:
a heating element configured to heat the outside air;
a humidifier configured to humidify the outside air that has passed through the heating element;
an airflow rate adjusting element configured to adjust a flow rate of processed air, which is a flow rate of the outside air to be supplied to the target space; and
a controller for outside air processing, the controller comprising processing circuitry that changes a target value of a temperature of the outside air to be supplied to the target space, in accordance with a humidity in the target space to change a temperature of the outside air at an inlet of the humidifier, wherein
the outside air processing device obtains the outside air independently from the air-conditioning device, and
if the humidity in the target space is lower than a predetermined humidity, and a heating load of the air-conditioning device is equal to or lower than a predetermined load, the processing circuitry of the controller for outside air processing increases the flow rate of the processed air.
