An engine driven heat pump includes a compressor clutch to switch between an ON state where drive from an engine is transmitted to a compressor and an OFF state where transmission of the drive from the engine to the compressor is cut off, an engine actuation battery to actuate the engine, a battery charging circuit configured to charge the engine actuation battery, and an inverter configured to convert output power from a generator into a predetermined voltage and a predetermined frequency, and when the compressor clutch is placed into the ON state from the OFF state or placed into the OFF state from the ON state during a self-sustaining operation, engine revolutions, which are revolutions of the engine, are set to reference revolutions required for the generator to supply predetermined power.
