    • Disclosed herein are a multi-air conditioner and a group-unit control method thereof, wherein a plurality of indoor units can be controlled on a group basis. The method comprises the step of grouping the indoor units into a plurality of groups, the step of if an air conditioning operation condition of a specific one of the indoor units is changed, sending, by the specific indoor unit, the changed operation condition to all the other indoor units according to a predefined communication protocol, and the step of by each of the indoor units, receiving an air conditioning operation condition sent from a different one of the indoor units in the same group and performing an air conditioning operation based on the received operation condition. According to the invention, the plurality of indoor units can be more efficiently controlled on a group basis through inter-indoor unit data communication. Further, the group-unit control is not restricted by whether a controller is used or not. Moreover, it is easy to add or change an object to which the group-unit control is to be applied.
    • 这里公开了一种多空调机及其组合单元控制方法,其中可以基于组来控制多个室内机。 该方法包括:将室内机分组成多组的步骤,如果特定的一个室内机的空调运转状态发生变化,则由特定的室内机发送变更的运转状态为全部 根据预定义的通信协议的其他室内机,以及通过每个室内机的步骤,接收从同一组中的不同的一个室内单元发送的空调操作条件,并且基于该空调操作 接收运行状态。 根据本发明,可以通过室内单元数据通信,以组为基础来更有效地控制多个室内机。 此外,组单元控制不受使用控制器的限制。 此外,容易添加或更改要应用组单元控制的对象。

    • 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​​。
