Air conditioner pipeline device and air conditioner

An air conditioner pipeline device, comprising:

• a gaseous refrigerant connecting pipe, configured to be connected between an indoor unit and an outdoor unit of an air conditioner;
• a liquid refrigerant connecting pipe configured to be connected between the indoor unit and the outdoor unit of the air conditioner;
• an adapter comprising a main body part, an electrical connection structure and a connection terminal, the electrical connection structure is arranged in the main body part, the connection terminal is led out from the electrical connection structure and is connected to a power supply of the air conditioner;
• a first refrigerant pipe arranged in the indoor unit;
• and
• a second refrigerant pipe arranged in the outdoor unit;
• wherein at least one of the gaseous refrigerant connecting pipe and the liquid refrigerant connecting pipe adopts a multi-layer pipe, two ends of the multi-layer pipe respectively communicate with the first refrigerant pipe and the second refrigerant pipe through the adapter, the electrical connection structure has the same layer structure as the multi-layer pipe and is butted with the multi-layer pipe;
• and the multi-layer pipe comprises:
• at least two conductive pipes, sequentially and coaxially sleeved along a radial direction of the multi-layer pipe, and configured to be connected to a power supply of the air conditioner to transmit power to the air conditioner, an internal area of the innermost layer of conductive pipe being configured to allow a refrigerant to flow, and
• a first insulating layers, arranged between the adjacent conductive pipes of the at least two conductive pipes, and/or arranged on an outer surface of the outermost layer of the at least two conductive pipes.
