PROBLEM TO BE SOLVED: To provide an air conditioning system capable of securing the opportunity of the ventilation of indoor air while suppressing an excessive increase in the load of an air conditioner during a heating operation.SOLUTION: An air conditioning system includes: an air conditioner; and a ventilation device that includes a total enthalpy heat exchanger. The air conditioner performs, during a heating operation, a temperature control operation for controlling a room temperature, and at least one type of non-temperature control operations not for controlling the room temperature but generating a heating load. The ventilation device ventilates air in a normal ventilation mode for setting a ventilation amount to be equal to or higher than a predetermined ventilation amount if the air conditioner performs the temperature control operation. The ventilation device ventilates the air in a ventilation suppression mode for increasing a rotational speed of an exhaust fan to be higher than that of an air supply fan to set an indoor voltage to a negative voltage, and for ventilating the air at a smaller value than the predetermined ventilation amount or stopping ventilation if the air conditioner executes one of the operations included in the non-temperature control operations. In the ventilation suppression mode, furthermore, as the heating load increases due to the ventilation during the non-temperature control operation, the ventilation amount is made smaller. |
