Abstract: An air conditioner includes a bypass pipe connecting a first bypass branch of a first connection pipe, through which high-pressure refrigerant flows, with a second bypass branch of a third connection pipe, through which low-pressure refrigerant flows, to allow bypassing of high-pressure refrigerant in the first connection pipe to the third connection pipe, and a bypass valve mounted in the bypass pipe. During a cooling operation of an indoor unit, the bypass valve is opened to allow bypassing of high-pressure refrigerant of the first connection pipe to the third connection pipe.

Abstract: An air conditioner is provided. The air conditioner may include a compressor, a condenser, an evaporator, a receiver storing a portion of a refrigerant passing through the condenser, an accumulator receiving refrigerant stored in the receiver and refrigerant passing through the evaporator to separate gas refrigerant from refrigerant introduced therein and supply the gas refrigerant to the compressor, and a bypass line supplying refrigerant from the receiver to the accumulator. The receiver and the accumulator may be integrally formed or provided as separate parts coupled each other. An outlet end of the bypass line may be connected to an upper portion of the accumulator. Such an arrangement may prevent refrigerant from flowing backward from the accumulator into the receiver.
Abstract translation: 提供空调。 空调可以包括压缩机，冷凝器，蒸发器，存储通过冷凝器的制冷剂的一部分的接收器，容纳储存在接收器中的制冷剂的储存器和通过蒸发器的制冷剂，以将从其中引入的制冷剂中分离的气体制冷剂和 将气体制冷剂供应到压缩机，以及将制冷剂从接收器供应到蓄能器的旁路管线。 接收器和蓄电池可以一体地形成或设置成彼此耦合的分离部件。 旁路管路的出口端可以连接到蓄电池的上部。 这种布置可以防止制冷剂从蓄能器向后流动到接收器中。

Abstract: Provided is an air conditioning apparatus. The air conditioning apparatus includes an outdoor unit through which a refrigerant is circulated, an indoor unit through which water is circulated, and a heat exchange device including a heat exchanger in which the refrigerant and the water are heat-exchanged with each other. The heat exchanger includes a high-pressure guide tube, a low-pressure guide tube, a liquid guide tube, a bypass tube configured to connect a bypass branch point of the high-pressure gas tube of the outdoor unit to a bypass combination point of the liquid guide tube to bypass a high-pressure refrigerant existing in the high-pressure tube to the liquid guide tube, and a bypass valve installed in the bypass tube. The outdoor unit includes a first valve device configured to guide a refrigerant compressed in the compressor to the outdoor heat exchanger and a second valve device configured to guide the refrigerant compressed in the compressor to the high-pressure guide tube of the heat exchange device.
