Centrifugal fan assembly and air conditioning device

The invention relates to a centrifugal fan assembly. The centrifugal fan assembly comprises a volute, an electromotor, a centrifugal impeller and a volute installation board, wherein the electromotor is fixedly installed on the volute; the centrifugal impeller is installed on a shaft of the electromotor and is driven by the electromotor; the volute is installed on the volute installation board. The centrifugal fan assembly is characterized in that at least three exhaust outlets are formed in the volute and can exhaust air in multiple directions at the same time. The centrifugal fan assembly is provided with the three exhaust outlets, so that the large-range air supplying effect of feeding air in one direction and exhausting air in three directions is achieved; meanwhile, as the speeds of the exhaust outlets are evenly distributed, compared with one-way and two-way fans, the whole fan is good in balance performance and small in vibration.
