如图1所示，本公开实施例提供了一种变频空调器的控制方法，包括：
S1，根据预设温度Ts与室内环境温度Tin计算出目标频率f；
可选地，例如可以选择制冷模式开机，空调器可以设置有实时检测模块70、计算模块10、判断模块20和控制模块30，实时检测模块70通过温度传感器获得室内环境温度Tin和预设温度Ts(也就是用户设定温度)，当然也可以通过其他模块直接获得预设温度Ts和室内环境温度Tin，再通过计算模块10计算出目标频率f。
S2，判断目标频率f是否大于绕组分界点频率f4，若f大于等于f4，选择电动机的第一绕组方式并使空调压缩机运行至一个停顿平台的频率持续预设时间，使空调压缩机运行至绕组分界点频率f4，切换至电动机的第二绕组方式接线，使空调压缩机运行至一个停顿平台的频率持续预设时间，使空调压缩机运行至目标频率f。
在步骤S2中，可选地，若f大于等于f4，选择所述第一绕组方式并使空调压缩机按照第一预设运行速度V1运行至第一停顿平台的频率持续第一停顿时间t1，在第一停顿时间t1结束后使空调压缩机按照预设运行速度V运行至绕组分界点频率f4，切换至所述第二绕组方式接线，使空调压缩机按照第二预设运行速度V2运行到第二停顿平台持续第二停顿时间t2；在第二停顿时间t2结束后再按照第三预设运行速度V3运行至目标频率f，空调压缩机的电动机绕组为阻抗较大的第一绕组和阻抗较小的第二绕组，第一停顿平台的频率为f1，第二停顿平台的频率为f2，f1小于f4，f2大于f4。
可选地，在上述操作中可以设置电动机的第一绕组方式为Y型，第二绕组方式为三角型，两种绕组方式的绕线切换分界点频率即绕组分界点频率f4为65Hz(可根据电动机绕组参数进行调整)，通过绕组切换部切换所述电动机的绕组结构，使其选择Y型还是三角型接线方式，设第一停顿平台的频率为f1(45Hz可调)时间为t1(1min可调)；第二停顿平台的频率为f2(76Hz可调)时间为t2(1min可调)。
在一些实施例中，根据预设温度Ts与室内环境温度Tin的差值△T计算出目标频率f。
在上述操作中也可以通过获得空调室内机的室内环境温度Tin和预设温度Ts，计算出室内环境温度Tin与预设温度Ts的差值△T，△T＝Tin-Ts，然后通过计算模块10计算出目标频率f。
如图2所示，在一些实施例中，所述的方法还包括：S101，根据空调室内风机的风挡 对目标频率f进行修正，当空调室内风机风挡的风速r≤r1，目标频率负向修正；当r＞r2目标频率正向修正，其中r1和r2为预设风速值。
当空调室内机存在不同风挡时，通过上述计算得出的目标频率f之后，再根据空调室内风机的风挡对目标频率f进行修正；当空调室内风机风挡的风速r≤r1，目标频率负向修正，防止凝练或者冻结发生；当r1＜r≤r2目标频率不做修正；当r＞r2目标频率正向修正，防止过热度偏大，降低蒸发器能力输出；判断目标频率f是否大于绕组分界点频率f4，f大于等于f4，则先选择第一绕组方式并使空调压缩机按照V1为2Hz/s运行至第一停顿平台的频率f1持续第一停顿时间t1(1min可调)，在第一停顿时间结束后使空调压缩机按照预设运行速度V为0.5Hz/s运行至绕组分界点频率f4，此时切换第二绕组方式接线，再按照V2为2Hz/s运行到第二停顿平台的频率f2持续第二停顿时间t2(1min可调)，在第二停顿时间结束后再按照V3为2Hz/s运行至目标频率f，以快速达到换热效果，使压缩机运行更加平稳。
空调压缩机按照预设的运行速度不仅限于0.5或2Hz/s，可以根据需要做调整。
可选地，在空调室内机存在风挡时，目标频率f＝k1*r+k2*△T+b+c，其中k1为转速系数；k2为温差系数；b为常数,r为空调室内风机的转速，c为频率修正值，0＜k1＜1，1<k2<3。
举例以k1＝0.025；k2＝2.212；b＝0.533(b可以根据实际需要取不同的常数数值)，同时设定室内风机风挡设定静音、低风、中风、高风、强力，对应转速r分别为500rpm、800rpm、1200rpm、1500rpm、1700rpm(rpm是Revolutions Per minute的缩写，是转/每分钟)；
设0≤△T<5℃、5≤△T<10℃、10≤△T<15℃、15≤△T<20℃、20≤△T<27℃、≥27℃，这里取计算出的△T＝25℃，根据f＝k1*r+k2*△T+b+c，根据当前室内风机风挡的风速确定c，计算出f，进而在步骤S2中判断出f大于f4，则先选择Y型绕组方式，并使空调压缩机按照V1为2Hz/s运行至第一停顿平台的频率f1持续第一停顿时间t1(1min可调)，在第一停顿时间结束后使空调压缩机按照预设运行速度V为0.5Hz/s运行至绕组分界点频率f4，此时切换第二绕组方式接线，再按照V2为2Hz/s运行到第二停顿平台的频率f1持续第二停顿时间t2(1min可调)，在第二停顿时间结束后再按照V3为2Hz/s运行至目标频率f。反之，若计算出的f小于f4，则选择Y型绕组方式并使空调压缩机可以按照0.5Hz/s运行至到目标频率。
在步骤S2中，使所述电动机与所述空调压缩机之间通过绕组切换部连接，用所述绕组切换部切换所述电动机的绕组结构，根据判断f与f4的大小结果控制所述绕组切换部切换动作。
电动机是具有U相、V相、W相的三相绕组的三相电动机，电动机的各相绕组的两个端子与所述绕组切换部连接，所述绕组切换部通过切换所述端子的连接，来切换成作为所述第一绕组方式的Y型绕组连接或作为所述第二绕组方式的三角型绕组连接。
可选地，在空调室内机无风挡时，即静音模式，目标频率f＝k1*r+k2*△T+b，其中k1为转速系数；k2为温差系数；b为常数,r为空调室内风机的转速，0＜k1＜1，1<k2<3。
举例以k1＝0.025；k2＝2.212；b＝0.533(b可以根据实际需要取不同的常数数值)，同时设定室内风机静音时的转速r＝500rpm(rpm是Revolutions Per minute的缩写，是转/每分钟)；
设0≤△T<5℃、5≤△T<10℃、10≤△T<15℃、15≤△T<20℃、20≤△T<27℃、≥27℃，这里取计算出的△T＝25℃，根据f＝k1*r+k2*△T+b计算出f＝68.3333Hz，进而在步骤S2中判断出f大于f4，则先选择Y型绕组方式，并使空调压缩机按照V1为2Hz/s运行至第一停顿平台的频率f1持续第一停顿时间t1(1min可调)，在第一停顿时间结束后使空调压缩机按照预设运行速度V为0.5Hz/s运行至绕组分界点频率f4，此时切换第二绕组方式接线，再按照V2为2Hz/s运行到第二停顿平台的频率f2持续第二停顿时间t2(1min可调)，在第二停顿时间结束后再按照V3为2Hz/s运行至目标频率f。反之，若计算出的f小于f4，则选择Y型绕组方式并使空调压缩机可以按照0.5Hz/s运行至到目标频率。
