Abstract

An air return pipe (1) for an air conditioner, and an air conditioner, aiming to solve the problem in the prior art that because most recreational vehicle air conditioner pipes, especially air return pipes, are designed as copper pipes, there is a risk of pipe breakage due to long-time pipe vibration during the driving and parking of recreational vehicles. To achieve this objective, the air return pipe (1) is configured to comprise a first straight line section (101), a first bent section (102), and a communication section, the first straight line section (101) being connected to an air return interface of a liquid storage tank (3), and the included angle between the center line of the top-view projection of the first bent section (102) and the center line of an exhaust interface of a compressor (2) being less than 90°. The included angle between the center line of the top-view projection of the first bent section (102) and the center line of an exhaust interface pipe (4) of the compressor (2) is designed to be less than 90°, so that the transmission of mechanical vibration generated by the compressor (2) to the air return pipe (1) can be reduced, preventing the air return pipe (1) from resonating in the working frequency range of the compressor (2), thereby reducing the risk of breakage of the air return pipe (1) and a welding position.
