The invention discloses a frequency control method for an air-conditioning system. The method includes: obtaining a first rated frequency and a first capacity demand value of an air conditioner external unit, and a second capacity demand value corresponding to each target air conditioner interior unit. , wherein, the target air conditioner internal unit is an air conditioner internal unit in a running state; the capacity utilization rate corresponding to the air conditioner external unit is determined according to the first capacity demand value and each second capacity demand value; according to the first rated capacity The frequency and the capacity utilization rate determine a target frequency, and the compressor of the external unit of the air conditioner is controlled to operate according to the target frequency. Through the frequency control method in the present invention, the operating frequency of the compressor can be adjusted according to the capacity utilization rate of the external unit of the air conditioner, so that the operating frequency of the compressor can meet the capacity requirement of the internal unit of the air conditioner, and the operating frequency of the compressor can be avoided from being too high or too high. A situation that does not match the capacity demand of the air conditioner's internal unit caused by too low.
Description
technical field [0001] The present invention relates to the technical field of household electrical appliances, in particular to a frequency control method, a storage medium and an air conditioning system. Background technique [0002] At present, the household free one-drive-multiple air-conditioning system mainly includes one outdoor unit and multiple indoor units that are matched with the outdoor unit at the same time. Sometimes the outdoor unit is also used with different types of indoor units at the same time. In the process of use, due to the need to turn on different numbers of indoor units, there is often a situation where the compressor frequency of the indoor unit of the air conditioner does not match the capacity requirements of the indoor unit of the air conditioner. For example, the compressor frequency is low or high. Insufficient or excessive cooling and heating capacity of the compressor. [0003] Therefore, the existing technology still needs to be improved...
