To reduce frequency of start and stop of an air conditioner, and to reduce running costs of an air conditioning system, in the air conditioning system comprising the air conditioner and an outside air processor.
This air conditioning system (10) is constituted by the air conditioner (20) and the outside air processor (50). The air conditioner (20) repeats the stop and start so that an indoor air temperature reaches a value within a range of a target temperature. On the other hand, the outside air processor (50) is necessarily operated during the operation of the air conditioning system (10). A control system (90) decreases a rotating speed of each of indoor fans (24a-24d) to reduce a flow rate of the air supplied indoors by each of indoor units (22a-22d), when a measured value of an indoor temperature sensor (55a) reaches a reference value for reducing air volume during a cooling operation or a heating operation. When the flow rate of the air supplied indoors from each of the indoor units (22a-22d) is reduced, the cooling capacity or the heating capacity of each of the indoor units (22a-22d) is lowered, and rapidity of change of the indoor temperature is moderated.
