Abstract: An air conditioner is provided. The air conditioner may include a subcooling heat exchanger that evaporates a refrigerant, a compressor that compresses the refrigerant, an injection flow channel through which the evaporated refrigerant flows into the compressor, an injection valve that opens and closes the injection flow channel, an oil separator that separates oil from refrigerant discharged from the compressor, and an oil injection line, which communicates at a first end thereof with the oil separator and at a second end thereof with the injection flow channel so as to guide the oil separated by the oil separator toward the injection flow channel. The oil separated by the oil separator may selectively flow into the compressor through the oil injection line and the injection flow channel in accordance with a mode of operation of the air conditioner.

Abstract: An air conditioner is provided. The air conditioner may include a supercooling heat exchanger that evaporates a refrigerant, a compressor that compresses the refrigerant, an injection flow channel through which the evaporated refrigerant flows into the compressor, an injection valve that opens and closes the injection flow channel, an oil separator that separates oil from refrigerant discharged from the compressor, and an oil injection line, which communicates at a first end thereof with the oil separator and at a second end thereof with the injection flow channel so as to guide the oil separated by the oil separator toward the injection flow channel. The oil separated by the oil separator may selectively flow into the compressor through the oil injection line and the injection flow channel in accordance with a mode of operation of the air conditioner.

Abstract translation: 提供空调。 空气调节器可以包括使制冷剂蒸发的过冷却热交换器，压缩制冷剂的压缩机，蒸发的制冷剂流入压缩机的喷射流路，打开和关闭喷射流路的喷射阀，油分离器 其将油与从压缩机排出的制冷剂分离，以及注油管路，其在其第一端与油分离器连通，并在其第二端与注入流动通道连通，以便将由油分离器分离的油导向 注射流通道。 由油分离器分离的油可以根据空调的运转方式，通过注油管路和注入流路选择性地流入压缩机。
