Processing method for compressor faults of some outdoor units of multi-coupled air conditioner during heating process

The invention discloses a processing method for compressor faults of some outdoor units of a multi-coupled air conditioner during a heating process. The processing method comprises the following steps: using a connecting pipeline (2) with a ball valve (1) for connecting an outlet of an outdoor heat exchanger (3) of each outdoor unit with the outlet of the outdoor heat exchanger (3) of an adjacent outdoor unit; normally running each outdoor unit under a heating mode; opening the ball valve (1) of the connecting pipeline (2) between a fault outdoor unit and an adjacent normal outdoor unit after a compressor (4) of one outdoor unit is in fault and cannot normally work. According to the processing method, a specially-assigned person does not need to repair on-site and the self-regulation of the machine unit can be utilized to quickly and efficiently solve the problem of insufficient heat exchange amount caused by the faults of part of compressors.
