ENGINE DRIVEN HEAT PUMP

摘要

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.

1. An engine driven heat pump, comprising:
an engine; a compressor configured to be driven by the engine; a refrigerant circuit configured to flow a refrigerant sucked and discharged by the compressor; a generator configured to be driven by the engine; a compressor clutch configured to switch between an ON state where drive from the engine is transmitted to the compressor and an OFF state where transmission of the drive from the engine to the compressor is cut off; an engine actuation battery configured to actuate the engine; a battery charging circuit configured to charge the engine actuation battery; and an inverter configured to convert output power from the generator into a predetermined voltage and a predetermined frequency, wherein 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.
