In the present invention, an air conditioning device is provided with a refrigerant circuit through which a refrigerant flows, a heating medium circuit through which a heating medium flows, and an air release device. In the refrigerant circuit, a compressor, a heat source-side heat exchanger, a throttling device, and a heating medium heat exchanger for carrying out heat exchange between the refrigerant and the heating medium are connected by refrigerant pipelines. In the heating medium circuit, a pump for feeding the heating medium, a usage-side heat exchanger, and the heating medium heat exchanger are connected by heating medium pipelines. The air release device has: a heating medium tank connected to the heating medium circuit, said tank separating air and the heating medium within the heating medium circuit; and an air-releasing air bleed valve provided to the heating medium tank. |
