The indoor unit includes: a heat exchanger; an indoor temperature detection means for detecting an indoor temperature; and a valve for adjusting the flow rate of a refrigerant flowing in a refrigeration cycle. The outdoor unit includes: a heat exchanger; a compressor; a frequency detection means for detecting the operation frequency of the compressor; and a valve for adjusting the flow rate of the refrigerant flowing in the refrigeration cycle. The air conditioning system further includes a control means for controlling the opening degree of the valve of the indoor unit depending on the indoor temperature detected by the indoor temperature detection means, the amount of change in the indoor temperature over a predetermined period of time, and the operation frequency detected by the frequency detection means.
