    • 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。
