To provide an air conditioning device which can be improved in a heat carrying power to reduce power consumption by securing amenity while suppressing a construction period and construction costs.
An air conditioning device includes: refrigerant systems 1, 2 having an outdoor unit 10 and indoor unit 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: an 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 blowoff air which is blown off 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 an air conditioning zone of the refrigeration system which is determined as being subjected to a low load.
