Beschreibung
Zusammenfassung:	The invention simplifies the H-bridge circuit of the direct current motor for driving the dampers (doors) that switch the ventilation trunk in the indoor unit of an air conditioning device. The control device for an air conditioning device (1) that takes in indoor or outdoor air and conditions the air inside an air conditioning unit (1A) using an evaporator (6) and a heater core (7) is provided with: a first actuator (M1) and a second actuator (M2) that drive the multiple dampers installed inside the air conditioning unit (1A) for switching the air flow path; and three half-bridge circuits (31, 32, 33) that control the first actuator (M1) and the second actuator (M2) sharing one half-bridge circuit (32). Of the multiple dampers, the first actuator (M1) is connected to the indoor/outdoor air switching damper (4). Of the multiple dampers, the second actuator (M2) is connected to at least one air mixing damper (11a, 11b).
