Air conditioning system

An air conditioning system comprising:

• an air conditioning room configured to introduce air from outside;
• an air conditioner disposed in the air conditioning room and adjusting temperature of the air in the air conditioning room;
• a humidifier disposed in the air conditioning room and humidifying the air temperature-adjusted by the air conditioner;
• a plurality of transfer fans transferring the air in the air conditioning room to a plurality of air-conditioned spaces independent of the air conditioning room, respectively;
• and
• a controller controlling the humidifier,
• wherein the controller:
• acquires, as a first humidity, information related to detected humidity of the air detected in each of the plurality of air-conditioned spaces,
• causes the humidifier to execute a first humidifying control based on an average value of respective first humidities in the plurality of the air-conditioned spaces;
• in response to elapse of a predetermined time after causing the humidifier to execute a first humidifying control, acquires, as a second humidity, information related to detected humidity of the air detected in each of the plurality of air-conditioned spaces;
• and
• causes the humidifier to switch to and execute a second humidifying control based on an average value of respective second humidities in the plurality of the air-conditioned spaces in the case of a first humidity difference between the second humidity in one air-conditioned space of the plurality of the air-conditioned spaces and the average value of the respective second humidities in the plurality of the air-conditioned spaces being less than or equal to a first threshold value, and causes the humidifier to continue to execute the first humidifying control in the case of the first humidity difference being more than the first threshold value.
