The present application relates to the technical field of air conditioner pipe fittings, and discloses a wall bushing assembly, comprising: a fresh air pipe, wherein a fresh air pipe cavity is formed inside the fresh air pipe; and a wire harness pipe, attached to the fresh air pipe side by side in the same direction, wherein a wire harness pipe cavity is formed inside the wire harness pipe, and an installation opening which extends and is formed in the pipe length direction and is used for installing a wire harness group in the wire harness pipe cavity is formed in the attached surface of the wire harness pipe. The attached surface of the fresh air pipe can seal the installation opening after the wire harness pipe is attached to the fresh air pipe. According to the wall bushing assembly in embodiments of the present disclosure, the wire harness group and a fresh air channel are separated by means of the fresh air pipe and the wire harness pipe, such that mutual interference between the wire harness group and the fresh air channel can be avoided; moreover, the wire harness group is installed by means of the installation opening formed in the wire harness pipe, and the installation opening is sealed by means of the fresh air pipe, such that the structure is simple, and installation is rapid and convenient. The present application further discloses an air conditioner.
