The invention relates to the technical field of air conditioner control, in particular to a pure electric intelligent air conditioner frequency converter carrier frequency control method and system. The method comprises the steps that whether the air conditioner is switched from a segmented fixed carrier frequency control mode to a self-adaptive carrier frequency control mode or not is judged according to the load demand degrees of all moments within the preset time of the initial operation stage of the air conditioner; in the stable operation stage of the air conditioner, a mode switching factor corresponding to the sampling moment is obtained according to the load demand change degrees of the preset sampling moment, the moment before the sampling moment and the moment after the sampling moment, the average value of the load demand degrees before the sampling moment and the load demand degree at the moment after the sampling moment; and when the normalized value of the mode switching factor has a cross-mode switching threshold behavior, switching the air conditioner into another frequency control mode, and solving a frequency value of the other frequency control mode. According to the method, the frequency control mode can be adaptively determined according to the load demand change of the external environment in the operation of the air conditioner.

    本发明涉及空调控制技术领域,具体涉及一种纯电动智能空调变频器载波频率控制方法及系统,方法包括:在空调初始运行阶段的预设时间内各时刻的负载需求度来判断是否将空调从分段固定载波频率控制模式切换为自适应载波频率控制模式;在空调稳定运行阶段,根据预设采样时刻、采样时刻前一时刻以及采样时刻后一时刻的负载需求变化程度、采样时刻前的负载需求度的平均值以及采样时刻后一时刻的负载需求度来获取采样时刻对应的模式切换因子,当模式切换因子的归一化值存在跨模式切换阈值行为,则将空调切换为另一频率控制模式,并求取另一频率控制模式的频率值。本发明能针对空调运行中外界环境的负载需求变化自适应的确定频率控制模式。
