Abstract

The invention discloses a control method and device of a multi-fan system. The control method comprises: obtaining a starting sequence of a plurality of fans to be started in the multi-fan system; and sequentially generating a starting signal for each fan to be started according to the starting sequence so as to start the plurality of fans to be started. The control method and device solve the technical problem that the existing control method of the multi-fan system cannot lower the starting noise of the fan system of an air conditioner, and realize the effects that the multi-fan system can be reliably started under various loads, and at the same time, the starting noise is lowered.

Description

technical field [0001] The present invention relates to the field of air conditioner fan control, in particular to a control method and device for a multi-fan system. Background technique [0002] At present, the air conditioner with more than two fan systems makes a lot of noise when multiple fans are started at the same time, and the fan speed is unstable, which is easy to cause damage to the fan blades. In order to reduce the starting noise of the fan, the traditional method is to reduce the starting speed of the fan, but this method will cause the fan under heavy load to fail to start successfully. [0003] Aiming at the above-mentioned problem that the start-up method of the existing multi-fan system cannot reduce the start-up noise of the fan system of the air conditioner, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a control method and device for a multi-fan system to at least solve th...
