Abstract

The invention discloses a control method and device for a multi-split air conditioner, and belongs to the technical field of air conditioners. The method comprises the following steps that operation signals of indoor units are acquired; and the rotation speed of an outdoor fan is adjusted according to the number of the operation signals. The method and the device can solve the problems that in theoperation process of the multi-split air conditioner, when the single indoor unit operates, protective frequency reduction occurs, operation of a compressor is unstable, and when the multiple indoorunits operate, the use effect of a user is poor so as to meet different requirements of the operated indoor units with different numbers on the rotation speed of the outdoor fan.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method and device for one-driver-multiple air conditioners. Background technique [0002] At present, the control logic of the outdoor fan of a multi-device air conditioner is mainly judged by the external environment temperature, and only different outdoor fan speeds are adjusted according to different external ambient temperature ranges, and has nothing to do with the operation of the indoor unit. At present, one-to-many outdoor fans are controlled, and when the outer ring temperature is constant, when one indoor unit is running and multiple units are running at the same time, the outdoor fans are at the same speed, which is prone to protective frequency reduction when a single indoor unit is running, and the compressor The operation is unstable, and the user's use effect is not good when multiple indoor units are running. Contents of the invention [0003...
