Abstract

The invention provides a frequency control method and device for a multi-split air conditioner and an air conditioning system. The method comprises the steps that under the condition that an outdoor unit is started or the load of the multi-split air conditioner changes suddenly, the multi-split air conditioner is controlled to enter a frequency modulation mode, and the frequency modulation mode is a mode for controlling the frequency change rate of the multi-split air conditioner to be in a first preset range; a target frequency is calculated according to a current operation parameter and a current environment parameter; the operation frequency of the multi-split air conditioner is adjusted to a target frequency; and under the condition that the frequency modulation mode of the multi-split air conditioner reaches a first preset time or the multi-split air conditioner operates at the target frequency for a second preset time, the multi-split air conditioner is controlled to enter a stable mode, the stable mode is a mode for controlling the frequency change rate of the multi-split air conditioner to be in a second preset range, and the interval of the second preset range is a subinterval of the interval of the first preset range. The problem that in the prior art, when the load of the multi-split air conditioner changes suddenly, the frequency cannot be adjusted in time, and consequently comfort is poor is solved.

Description

technical field [0001] The present application relates to the technical field of multi-connected air conditioners, in particular, to a frequency control method, device, computer-readable storage medium, processor and air-conditioning system for multi-connected air conditioners. Background technique [0002] The multi-connected air conditioning system is a system in which one outdoor unit and one compressor drag multiple indoor units. The towed indoor units can be of different models and quantities, and can be freely matched and installed according to user needs, which is very flexible. In this way, there are various states when the user uses it. According to the operating internal unit, there are states such as turning on one indoor unit, opening multiple units, opening some indoor units during operation, and shutting down some indoor units. For each machine, there are differences in setting wind speed, setting temperature, humidity, etc. Therefore, the multi-connected air...
