<p>An air conditioning system is provided with: a plurality of air conditioners (10a-10c) that each comprise indoor units (12a-12c) and outdoor units (11a-11c); and a control unit (30) for performing rotation operation that sequentially causes a predetermined number of the plurality of air conditioners (10a-10c) to stop operating at a time. The control unit (30) is configured so that, when the air conditioners (10a-10c) that were stopped directly prior to the end of the previous rotation operation are designated as stopped units, the air conditioners (10a-10c) that were scheduled to stop operating after the stopped units in the previous rotation operation are made to stop operating first in the current rotation operation. In this way, deviation with respect to the air conditioners that are made to stop operating is minimized.</p>
