PROBLEM TO BE SOLVED: To provide a self-supporting engine-driven type air conditioning device that enables prevention of shortage of electric power supply even when engine speed is reduced during switching of a four-way selector valve.SOLUTION: When a switching actuation request of a four-way selector valve 26 is input during self-supporting heating operation, a controller 60 executes self-supporting control before defrosting, before the switching actuation of the four-way selector valve 26 is performed. In the self-supporting control before defrosting, the controller 60 controls the speed of the gas engine 10 and the magnitude of electric power supplied from the generator 40 to an electric driven component, so that the speed of the gas engine 10 is reduced to a first set speed R1 that is a predetermined low speed and the magnitude of the electric power supplied from the generator 40 to the electric driven component decreases. |
