<p>An air conditioning device is provided with: refrigerant systems (1, 2) having an outdoor unit (10) and indoor units (20) and air conditioning the same room (100); and a circulator (40) for making temperature distribution in the room uniform. A load on each of the refrigerant systems (1, 2) being operated is determined, and when it is determined on the basis of the result of the determination of the loads that an increase in the operational efficiency can be expected, the air conditioning device is operated as follows: the operation of a refrigeration system which is determined as being subjected to a low load is stopped; integrated system operation is performed, the integrated system operation being that in which operation is integrated into a refrigeration system which is determined as being subjected to a high load; and discharge air which is blown from the indoor unit (20) of the refrigeration system which is determined as being subjected to a high load is conveyed by the circulator (40) to the air conditioning zone of the refrigeration system determined as being subjected to a low load.</p> |
