The invention discloses a communication pipe for an air conditioner and the air conditioner. The communication pipe is suitable for being attached to the wall surface, and the communication pipe for the air conditioner comprises a first channel and a second channel. The first channel is close to the wall surface, at least part of the second channel is embedded in the first channel, and the secondchannel is located on the side, away from the wall surface, of the first channel. According to the communication pipe for the air conditioner, by constructing the first channel and the second channelwhich are independent of each other in the communication pipe, the first channel and the second channel can be correspondingly used for introducing outdoor fresh air and a connecting component, so that a connecting pipeline, namely the pipeline passing the connecting component, of the air conditioner and a fresh air pipeline, namely the pipeline passing the outdoor fresh air can be combined for unified installation, and thus the installation efficiency of the air conditioner can be improved.
