Wherein, can set up fresh air pipe 2 and include a plurality of sub-pipes, a plurality of sub-pipes arrange in proper order along fresh air pipe 2's length direction, and one of two adjacent sub-pipes is constructed for having great size, and another is constructed for having less size, and the sub-pipe of less size can extend to in the inner chamber of the sub-pipe of great size to make two adjacent sub-pipes can slip the cover towards one end each other. Therefore, the length of the fresh air pipe 2 can be adjusted in a telescopic manner by adjusting the overlapping size of the adjacent sub-pipes along the length direction. Therefore, the fresh air pipe 2 is not required to be processed on site, the fresh air pipe 2 can be suitable for the walls 200 with different thicknesses, the installation difficulty of the fresh air pipeline assembly 100 is reduced, and the satisfaction degree of users is improved.

According to the utility model discloses air conditioner, through the length adjustable who sets up fresh air pipe 2, in fresh air pipe 2's installation, need not carry out the field machining to fresh air pipe 2, can make fresh air pipe 2 be applicable to the wall body 200 of different thickness, reduced the installation degree of difficulty of air conditioner, reduced the noise and the piece that produce in the installation, do benefit to improvement user's satisfaction.
