S103：控制压缩机按照目标运行频率运行。
在获得目标运行频率后，控制压缩机按照该目标运行频率运行，从而实现室内环境温度调节。
S104：在室内环境温度达到预设温度的情况下，控制压缩机维持目标运行频率，调节空调的风机的转速以调节空调的换热量。
预设温度为用户设置的目标环境温度。在室内环境温度达到预设温度的情况下，控制压缩机维持该运行频率，不进行放频，通过调节风机的转速来实现空调换热量的调节，进而维持室内环境温度的稳定，无需不断切换压缩机频率来维持室内环境温度的稳定，产生的噪声较小。
可选地，调节空调的风机的转速以调节空调的换热量包括：室内环境温度达到预设温度后，获得预设时段内室内环境温度的温度变化率；根据目标运行频率和温度变 化率调节风机的转速。
预设时段可以为室内环境温度达到预设温度后的预设时长的时间段，例如室内环境温度达到预设温度后的三分钟内。压缩机的目标运行频率(即压缩机当前的运行频率)与空调的制热或制冷量有关，一般来看，压缩机的目标运行频率越大，空调的制热或制冷量越大，改变室内环境温度的能力越强，反之，压缩机的目标运行频率越小，空调的制热或制冷量越小，改变室内环境温度的能力越弱。综合根据压缩机的目标运行频率和室内环境温度实际的温度变化率来调节风机的转速，从而实现换热量的调节，能在不改变压缩机运行频率的情况下，更好地维持室内环境的稳定，提升用户体验。
可选地，根据目标运行频率和温度变化率调节风机的转速，包括：获得与目标运行频率和温度变化率所对应的转速变化值；在风机的当前转速的基础上，按照转速变化值降低风机的转速。
预先建立目标运行频率和温度变化率与风机的转速变化值的第二关联关系表。在第二关联关系表中，风机的转速变化值与压缩机的目标运行频率以及温度变化率正相关，即，压缩机的目标运行频率以及温度变化率越大，风机的转速变化值越大；压缩机的目标运行频率以及温度变化率越小，风机的转速变化值越小。基于确定的压缩机的目标运行频率和温度变化率，通过查找第二关联关系表确定风机的转速变化值，并按照该转速变化值调节风机的转速，实现换热量的调节，能在不改变压缩机运行频率的情况下，更好地维持室内环境的稳定，同时能够避免压缩机不断变频带来的噪声，提升用户体验。
采用本公开实施例提供的用于空调的控制方法，确定与室外环境温度和室内环境温度的第一温度差值对应的目标运行频率，并控制空调的压缩机按照该目标运行频率运行，在室内环境温度达到预设温度的情况下，控制压缩机维持目标运行频率，调节空调的风机的转速以调节空调的换热量。这样，根据当前室外环境温度情况和室内温度情况给定压缩机一个运行频率，并在室内环境温度达到预设温度的情况下，控制压缩机维持该运行频率，通过调节风机的转速来实现空调换热量的调节，进而维持室内环境温度的稳定，无需不断切换压缩机频率来维持室内环境温度的稳定，产生的噪声较小，用户使用体验更佳。
在一些实施例中，用于空调的控制方法还包括：检测压缩机的第一振动频率，以及空调的面板的第二振动频率；获得第一振动频率与第二振动频率的振动频率差值；在振动频率差值小于或等于预设振动频率差值的情况下，控制压缩机在目标运行频率 的基础上，降低频率运行。
压缩机的第一振动频率用于表示压缩机物理振动的快慢，空调的面板的第二振动频率用于表示空调面板物理振动的快慢。预设振动频率差值为前期试验过程中面板松动时测得的第一振动频率与第二振动频率的振动频率差值。在面板安装不牢固时，空调面板会随压缩机的振动产生共振现象，此时面板振动产生的噪声要大于压缩机切换频率运行时产生的噪声。因此通过第一振动频率与第二振动频率的振动频率差值与预设振动频率差值的关系来了解空调面板的安装情况，当振动频率差值小于或等于预设振动频率差值时，表明空调面板与压缩机存在共振现象，空调面板可能安装存在松动的问题，控制压缩机在目标运行频率的基础上，降低频率运行，避免空调面板在强烈振动下产生的噪声，并降低空调面板持续高频振动而发生坠落的风险。
可选地，控制压缩机在目标运行频率的基础上，降低频率运行，包括：获得室内环境温度与预设温度的第二温度差值；确定与第二温度差值对应的压缩机降频值；控制压缩机在目标运行频率的基础上，降低压缩机降频值运行。
这里，压缩机降频值与第二温度差值负相关，即，第二温度差值越大，压缩机降频值越小；第二温度差值越小，压缩机降频值越大。压缩机执行降频操作时，获得室内环境温度与预设温度的第二温度差值，通过第二温度差值来了解空调目前的制冷或制热情况，当第二温度差值较大时，表明室内环境温度还远远没有达到用户所需的目标温度(预设温度)，压缩机降频值小，控制压缩机在目标运行频率的基础上，稍许降低一些频率运行，当第二温度差值较小时，表明室内环境温度即将达到用户所需的目标温度(预设温度)，压缩机降频值大，控制压缩机在目标运行频率的基础上，降低较大频率运行，在降低空调面板在强烈振动下产生的噪声的同时，尽量保证空调的正常空气调节，提升用户体验。
可选地，用于空调的控制方法还包括：在振动频率差值小于或等于预设振动频率差值的情况下，发出提示信息；其中，提示信息用于提示用户面板安装故障。
当振动频率差值小于或等于预设振动频率差值时，表明空调面板与压缩机存在共振现象，空调面板可能安装存在松动的问题，及时提醒用户进行处理，保障用户的生命财产安全。
在一些实施例中，用于空调的控制方法还包括：获得空调室内机产生的噪声值；根据噪声值的大小控制空调的微孔导风板的开启角度。
声波在通过空调的微孔导风板时，在导风板的不规则微孔结构中不断发生反射， 会降低声波的强度。因此可以根据空调室内机的噪声值大小控制微孔导风板的开启角度，在不影响空调的正常制热或制冷操作的同时，能够适当降低空调内部产生的噪声值的大小，提升用户体验。
可选地，根据噪声值的大小控制空调的微孔导风板的开启角度，包括：在噪声值大于或等于第一预设噪声值的情况下，控制微孔导风板关闭；在噪声值大于或等于第二预设噪声值，且小于第一预设噪声值的情况下，控制微孔导风板打开至预设角度。
第一预设噪声值可以是用户设置的一个较大噪声值，该噪声值对用户的日常活动影响较大；第二噪声值可以是用户设置的一个较小噪声值，该噪声值对用户的日常活动影响较小。当噪声值大于或等于第一预设噪声值时，为更好地降低空调室内机的噪声，控制微孔导风板关闭；在噪声值大于或等于第二预设噪声值，且小于第一预设噪声值的情况下，控制微孔导风板打开至预设角度(例如打开30°)，在降低空调室内机噪声的同时，能够更好地保证空调的出风量(空调微孔出风量小于空调导风板开启时的出风量)，从而更好地维持空调的制热或制冷操作，提升用户体验。
