Abstract

A fan assembly, an air conditioner and an air conditioning system. The fan assembly includes an air duct volute (1), a motor bracket (4), and a double-suction centrifugal fan blades (2) disposed in the air duct volute (1); the air duct volute (1) is provided with a first air inlet (301) and a second air inlet (302) corresponding to air suction ports of the double-suction centrifugal fan blade; the motor bracket is disposed in the first air inlet and is connected with a motor of the double-suction centrifugal fan blades (2), and an air inflow area ratio of an air inflow area S1 of the first air inlet (301) to an air inflow area S2 of the second air inlet (302) meets: 0.55≤formula(1)≤0.8. By setting the air inflow areas of both sides of the air duct volute reasonably, a pressure difference generated in an air duct can be reduced, and the mutual impact of airflows is reduced, thereby increasing the air volume of a fan system.
