The second fresh air module 3 is disposed at the second end side 102 of the air conditioner body, the second fresh air module 3 can discharge indoor air in a controlled manner, and the second fresh air module 3 can introduce outdoor fresh air in a controlled manner. Wherein the first fresh air module 2 and the second fresh air module 3 are operated simultaneously, and one of them introduces outdoor fresh air and the other discharges indoor air. Simultaneously, outdoor fresh air is introduced and indoor air is discharged, so that continuous rising of indoor air pressure is avoided, and the efficiency of introducing the outdoor fresh air is improved. The air conditioner provided by the embodiment of the disclosure has higher efficiency of introducing outdoor fresh air and better fresh air exchanging effect, and is beneficial to improving the use experience of users.

The above description and the drawings illustrate embodiments of the disclosure sufficiently to enable those skilled in the art to practice them. Other embodiments may include structural and other modifications. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary.
