Patent Description:
An indoor unit and an outdoor unit of a split air conditioner are separated. A copper pipe is used for refrigerant transmission, and a conducting wire is used for power supply and communication. Two different work requirements of pipe connection and wiring increase the complexity of tools and skills. If the copper pipe and a cable are wound together and a protective layer such as sponge is added to an outer layer, a diameter of a pipeline is large and inconvenient to install, and the use of the cable will cause great waste.
