    • [PROBLEMS] When applying a conventional transmission method to an air conditioner already arranged in a building or a house, a portion between a coolant pipe as a communication medium and an in-room unit and an out-of-room unit should be insulated and the steel pipe in the vicinity of both ends of the coolant pipe should be replaced by an electrically insulating device. [MEANS FOR SOLVING PROBLEMS] An air conditioner includes an in-room unit (2) connected to one end of coolant pipes (3, 4) and an out-of-room unit (1) connected to the other end of coolant pipes (3, 4). The air conditioner is characterized in that a signal coupling unit (7) is arranged for coupling an AC control signal to the coolant pipes (3, 4) and causing a predetermined impedance for the AC electric signal. This configuration eliminates the need of the conventional electrically insulating device and can perform signal transmission between the in-room unit (2) and the out-of-room unit (1) with a simple device structure.
    • [问题]当将传统的传输方法应用于已经布置在建筑物或房屋中的空调机时,作为通信介质的冷却剂管道与室内单元之间的部分和室外单元应当被绝缘, 冷却剂管两端附近的钢管应由电绝缘装置代替。 解决问题的手段空调包括连接到冷却剂管道(3,4)的一端的室内单元(2)和连接到冷却剂管道的另一端的室外单元(1) 3,4)。 空调器的特征在于,信号耦合单元(7)被布置成用于将AC控制信号耦合到冷却剂管道(3,4)并且引起AC电信号的预定阻抗。 这种配置消除了常规电绝缘装置的需要,并且可以以简单的装置结构在室内单元(2)和室外单元(1)之间执行信号传输。
