Abstract:
An active noise reduction distribution box, an air conditioner pipeline system, and an air conditioner. The active noise reduction distribution box comprises a distribution box main body, a speaker, multiple error microphones, and a controller. The distribution box main body comprises an air inlet portion and at least two air outlet portions. An air inlet end of each air outlet portion is connected to an air outlet end of the air inlet portion. The number of error microphones is consistent with the number of air outlet portions. The speaker is provided at an outer wall of the air inlet portion, and one of the error microphones is correspondingly provided at an outer wall of one of the air outlet portions. The controller is respectively connected to the speaker and the error microphone by means of signal lines. Multiple through-holes are provided at a wall surface on which the air inlet portion makes contact with the speaker, and multiple through-holes are provided at a wall surface on which the air outlet portion makes contact with the error microphone. The active noise reduction distribution box achieves active noise reduction between an outlet of an air conditioner main unit and an inlet of an air distribution pipeline, thereby preventing noise of the air conditioner main unit from traveling along the air distribution pipeline.
