Beschreibung
Zusammenfassung:	In this air-conditioning device, indoor units each comprise a temperature sensor that measures a first temperature, which is a temperature of air for exchanging heat with a heat medium using an indoor heat exchanger, and a control device performs first control in a cooling/heating mixed operation mode in which a third heat-medium heat exchanger is used for cooling if an indoor unit having the largest difference between the first temperature measured by the temperature sensor and a target temperature of the indoor unit is performing a cooling operation, and the third heat-medium heat exchanger is used for heating if the indoor unit having the largest difference thereof is performing a heating operation.
