Abstract (en)

[origin: EP4043809A1] An air conditioner outdoor unit and a control method. The air conditioner outdoor unit comprises: a housing in which at least two compressors (550) are provided; at least two drive modules (400), each drive module respectively correspondingly driving one compressor (550); heat exchange blocks (100) of which different parts are respectively connected to different drive modules (400) in a thermal conductive mode; and a refrigerant pipe (200) in which a refrigerant is comprised, the refrigerant pipe being inserted into the heat exchange blocks (100) and capable of cooling the heat exchange blocks (100). The problem that a condensation phenomenon is easy to occur because the temperature of the drive modules (400) of multiple compressors (550) is not balanced is solved.
