    • Disclosed is an apparatus and method for preventing liquid refrigerant accumulation in an accumulator of an outdoor unit of an air conditioner. The method includes the steps of: determining a state of a compressor; if the compressor is in standby mode or off state, turning on a four-way valve; determining whether the state of the compressor in standby mode or off state continues longer than a predetermined amount of time; and if the state of the compressor continues longer than the predetermined amount of time, closing an expansion valve. Particularly, high-pressure refrigerant flows in the closed expansion valve while low-pressure refrigerant flows in a check valve through the four-way valve. The apparatus includes a suction pipe connected to spray oil of the accumulator to the compressor; a liquid recovery pipe with one end being connected to the suction pipe and the other end being connected to the accumulator; and a liquid recovery valve for controlling opening/closing of the liquid recovery pipe, in which a compressor of the air conditioner in cooling or heating mode is operated and a liquid recovery valve for controlling a liquid recovery pipe connected to the compressor and an accumulator is opened to reduce oil in the accumulator. According to the present invention, when the compressor is off, it is possible to prevent liquid refrigerant accumulation by changing refrigerant flow line to the accumulator and the refrigerant at the lower end of the accumulator can be recovered.
    • 公开了一种用于防止液体制冷剂积聚在空调的室外机的蓄能器中的装置和方法。 该方法包括以下步骤:确定压缩机的状态; 如果压缩机处于待机模式或关闭状态,打开四通阀; 确定压缩机的状态是否处于待机模式或关闭状态持续时间超过预定时间量; 并且如果压缩机的状态继续长于预定时间量,则关闭膨胀阀。 特别地,高压制冷剂在闭合膨胀阀中流动,而低压制冷剂通过四通阀在止回阀中流动。 该设备包括一个连接到压缩机上的蓄能器喷油的抽吸管; 液体回收管,其一端连接到吸入管,另一端连接到蓄能器; 以及用于控制液体回收管的打开/关闭的液体回收阀,其中操作冷却或加热模式的空调的压缩机和用于控制连接到压缩机和蓄液器的液体回收管的液体回收阀 打开以减少蓄能器中的油。 根据本发明,当压缩机关闭时,可以通过改变制冷剂流向蓄能器的流线来防止液体制冷剂的积聚,并且能够回收蓄能器的下端的制冷剂​​。
