本实施例所述的除湿控制方法对湿度的调节控制方式更加精细化，以便提高湿度控制精度。能够执行本实施例所述的除湿控制方法的空调机组在实际运行时，尤其是在湿度较大的环境中使用时，当湿负荷与机组的除湿量达到动态平衡时，此时空调机组无法再进一步更大程度的进行除湿操作了，该空调机组此时可以按照本实施例所述的控制方法，一方面，采用过热度控制方式使第一电子膨胀阀的开度保持在第一电子膨胀阀的目标开度值；另一方面，根据工控 参数信息确定当前控制方式，并根据当前控制方式(过热度控制方式、退出过热度控制方式和维持方式的一种)确定第二电子膨胀阀的目标开度值，然后再控制第二电子膨胀阀使其开度保持在第二电子膨胀阀的目标开度值，通过以上过程能够同时降低前侧蒸发器和后侧蒸发器的温度，从而使空调机组进一步进行除湿操作，增强除湿效果。
本实施例中将控制方式分为：过热度控制方式、退出过热度控制方式和维持方式，是对现有的对电子膨胀阀的控制只是根据温度的变化进行PID湿度控制方式的改进，本实施例通过对控制方式的优化，能够提高对湿度的控制精度，更好的加强空调机组除湿效果，使空调机组的除湿效果能够达到用户设定的湿度要求，提高用户体验。

本实施例所述的控制方法与前面所述的实施例相比，区别仅在于，本实施例增加了步骤S41获取开启加强除湿功能的控制指令的过程。本实施例所述的 方法在实际使用时，需要用户或者空调机组的控制模块发出开启加强除湿功能的控制指令，之后才能执行步骤S42-S44所述的处理步骤。本实施例在实际使用时，当没有获取到开启加强除湿功能的控制指令时，该空调机组会按照现有的除湿方式进行除湿操作，当现有的除湿方式不能达到用户设定的湿度要求时，可以是通过用户或者是通过空调机组向除湿控制装置发送开启加强除湿功能的控制指令，之后空调机组按照步骤S42-S44，即实施例一至三所述的方式进行除湿。
其中，通过空调机组向除湿控制装置发送开启加强除湿功能的控制指令，包括：
空调机组上的湿度检测模块检测环境中的空气湿度，并当环境中的空气湿度大于用户设定的湿度目标值时，向所述除湿控制装置发送开启加强除湿功能的控制指令。

具体的，在实际操作中，可单独通过控制第一电子膨胀阀的开度，将第一电子膨胀阀的开度调节到所述第一电子膨胀阀的目标开度值，以降低前侧蒸发器的蒸发温度，降低室内湿度；或者通过同时控制第一电子膨胀阀和第二电子膨胀阀的开度，将第一电子膨胀阀的开度调节到所述第一电子膨胀阀的目标开度值，将第二电子膨胀阀的开度调节到所述第二电子膨胀阀的目标开度值，以同时降低前侧和后侧蒸发器的蒸发温度，从而降低室内湿度。
