Claim Text:
1. An air conditioning system comprising an air conditioner that implements at least a heating operation and a ventilator including an exhaust fan to exhaust indoor air, an air supply fan to introduce outdoor air, and a total heat exchanger to exchange heat between the indoor air and the outdoor air, wherein during heating operation, the air conditioner implements a temperature controlling operation of controlling a room temperature and at least one type of operation not intended for temperature control that is not to control the room temperature, the operation not intended for temperature control generating a heating load, when the air conditioner implements the temperature controlling operation, the ventilator performs ventilation in a normal ventilation mode where a ventilation amount is set at a certain ventilation amount or more, when the air conditioner implements the operation not intended for temperature control, the ventilator performs ventilation in a ventilation suppressed mode where the number of rotations of the exhaust fan is made greater than that of the air supply fan to place indoor space in a negative pressure and ventilation is performed at an amount smaller than the certain ventilation amount or ventilation is stopped, and in the ventilation suppressed mode, the amount of ventilation by the ventilator is set to be smaller in response to a greater heating load that is increased by ventilation performed during the operation not intended for temperature control.
