Multi-split air separation oil return mechanism

The utility model relates to the technical field of air conditioners, in particular to a multi-split air separation oil return mechanism which comprises an air conditioner outdoor unit, an air suctionpipe connected between an air-liquid separator and a compressor, a capillary pipe connected in parallel between the air suction pipe and the air-liquid separator, and an electromagnetic valve. The oil return mechanism integrates the advantages of two oil return modes of oil return of the oil return hole and oil return of the capillary tube, solves the problem that the compressor is damaged by liquid impact in the operating states of oil return of the oil return hole, starting of a unit, defrosting and the like, and also solves the problem that the oil return effect of capillary tube oil return in a low-frequency band is poor. The oil return device has the advantages of high oil return efficiency and safety. 本实用新型涉及空调技术领域，具体为一种多联机气分回油机构，包括空调室外机，包括气液分离器，气液分离器与压缩机之间连接的吸气管，在所述吸气管和气液分离器之间并联连接的毛细管和电磁阀。所述回油机构融合了回油孔回油和毛细
