一拖多空调中，可根据蒸发器入口温度与出口温度之间的差值来调整对应室内机流经的冷媒流量，因此，需要蒸发器入口传感器以及蒸发器出口传感器来获取对应的温度。本公开实施例中，一拖多空调中，只需获取室内机的内盘管温度，以及环境温度，就可对室内机流经的冷媒流量进行控制，这样，该空调中的室内机与一拖一空调中的室内机一致，只有环境温度传感器和内盘管温度传感器，而不需要配置蒸发器入口传感器以及蒸发器出口传感器，减少了家用中央空调即一拖多空调中温度传感器，兼容了现有的室内机，实现了一拖一内机与一拖多内机的统一，即提高了一拖 多空调的兼容性以及节省了资源。
本公开实施例中，空调包括：室外机以及至少两个室内机，每个室内机通过一个对应的节流装置与室外机连接。
图1是根据一示例性实施例示出的一种空调的结构示意图。如图1所示，本实施例中，空调包括：室外机100，第一室内机200，第二室内机300，其中，第一室内机200中的蒸发器通过节流装置1与室外机100中的冷凝器连接，第二室内机300的蒸发器通过节流装置2与室外机100中的冷凝器连接。每个室内机中，只有对应的内环温传感器和内盘管传感器，这里，传感器即为温度传感器，用以检测对应的温度。可见，一拖多中室内机与一拖一室内机一致，室内机与室外机的连接也比较简单，没有蒸发器入口传感器或蒸发器出口传感器的连接。
这里，只有两个室内机，对于三个、四个以及N个室内机的结构也如此，每个室内机只需有两个对应温度传感器，，每个室内机通过一个对应的节流装置与室外机连接，具体就不一一例举了。
在上述空调中，可只需获取室内机的内盘管温度，以及环境温度，就可对室内机流经的冷媒流量进行控制。
图2是根据一示例性实施例示出的一种空调冷媒流量控制方法的流程图。如图2所示，空调冷媒流量控制的过程包括：
步骤201：获取室外机中压缩机的吸气温度，以及获取每个室内机的内盘管温度。
如图1所示，室外机的压缩机上配置了吸气传感器，从而，可通过吸气传感器获取室外机中压缩机的吸气温度Ts。同样，室内机中配置了内盘管传感器，即可通过内盘管传感器获取每个室内机的内盘管温度，分别为：Tm1、Tm2、…Tmn，即有n个室内机，对应有n个内盘管温度。
当然，其他可获取温度的检测装置也可应用于此，不限于温度传感器，或者通过软件公式计算获取温度也可应用于此。
步骤202：当吸气温度与内盘管平均温度之间的第一温度差值大于预设温度差值时，调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量增大，其中，内盘管平均温度为每个内盘管温度求和后的平均值。
步骤203：当第一温度差值小于预设温度差值时，调整至少一个节流装 置的参数，使得节流装置中流经的冷媒流量缩小。
已经获取了每个室内机的内盘管温度Tm1、Tm2、…Tmn，可得到内盘管平均温度△Tm，内盘管平均温度为每个内盘管温度求和后的平均值，即△Tm＝(Tm1+Tm2+…+Tmn)/n。
然后，获得吸气温度Ts与内盘管平均温度△Tm之间的第一温度差值Tsh，Tsh＝Ts-△Tm。可根据空调的型号，进行多次测试，可获得一个预设温度差值Tsh0，即预先配置一个预设温度差值Tsh0，这样，当第一温度差值大于预设温度差值时，调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量增大；而当第一温度差值小于预设温度差值时，调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量缩小。
本实施例中，节流装置可为电子膨胀阀时，若Tsh＞Tsh0时，可将至少一个电子膨胀阀的阀门调大，从而，该电子膨胀阀流经的冷媒流量增大，对应室内机中冷媒流量变大。若Tsh＜Tsh0时，可将至少一个电子膨胀阀的阀门调小，而该电子膨胀阀流经的冷媒流量缩小，对应的室内机流经的冷媒流量变小。对于其他节流阀的调整也可如此，若Tsh＞Tsh0时，可调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量增大，而Tsh＜Tsh0时，可调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量缩小，从而，改变对应室内机流经的冷媒流量。
可见，本公开实施例中，只需获取室内机的内盘管温度，以及环境温度，就可对室内机流经的冷媒流量进行控制，这样，该空调中的室内机与一拖一空调中的室内机一致，只有环境温度传感器和内盘管温度传感器，而不需要配置蒸发器入口传感器以及蒸发器出口传感器，减少了家用中央空调即一拖多空调中温度传感器，兼容了现有的室内机，实现了一拖一内机与一拖多内机的统一，即提高了一拖多空调的兼容性以及节省了资源。
当然，本公开实施例中，调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量增大的方式有很多，例如，随机调整一个、两个或多个节流装置的参数，使得节流装置中流经的冷媒流量增大。较佳地，可根据每个室内机的内盘管温度进行调整，包括：将每个内盘管温度与内盘管平均温度进行比较；若当前内盘管温度大于内盘管平均温度，将当前内盘管温度对应的室内机确定为第一室内机；调整第一室内机对应的第一节流 装置的参数，使得第一节流装置中流经的冷媒流量增大。
例如：分别将Tm1、Tm2、…Tmn与△Tm进行比较，若Tm2＞△Tm，则可将Tm2对应第2个室内机确定为第一室内机，将第2个室内机对应的节流装置2确定为第一节流装置，调整节流装置2的参数，使得节流装置2中流经的冷媒流量增大。若节流装置2为电子膨胀阀，可将电子膨胀阀的阀门开大，阀门开大执行的步数可根据[Tsh-Tsh0]确定。同样，若Tm3、Tm6…Tmn都分别大于△Tm，则可对应的第3个室内机、第6个室内机…第n个室内机都确定为第一室内机，将对应的节流装置3、节流装置6…节流装置n确定为第一节流装置，调整第一节流装置的参数，使得第一节流装置中流经的冷媒流量增大。
同样，本公开实施例中，调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量缩小的方式有很多，例如，随机调整一个、两个或多个节流装置的参数，使得节流装置中流经的冷媒流量缩小。较佳地，可根据每个室内机的内盘管温度进行调整，包括：将每个内盘管温度与内盘管平均温度进行比较；若当前内盘管温度小于内盘管平均温度，将当前内盘管温度对应的室内机确定为第二室内机；调整第二室内机对应的第二节流装置的参数，使得第一节流装置中流经的冷媒流量缩小。
例如：分别将Tm1、Tm2、…Tmn与△Tm进行比较，若Tm1＜△Tm，则可将Tm1对应第1个室内机确定为第一室内机，将第1个室内机对应的节流装置1确定为第二节流装置，调整节流装置1的参数，使得节流装置1中流经的冷媒流量缩小。若节流装置1为电子膨胀阀，可将电子膨胀阀的阀门关小，阀门关小执行的步数可根据[Tsh-Tsh0]确定。同样，若Tm4、Tm5…都分别小于△Tm，则可对应的第4个室内机、第5个室内机…都确定为第二室内机，将对应的节流装置4、节流装置5…确定为第二节流装置，调整第二节流装置的参数，使得第二节流装置中流经的冷媒流量缩小。
可见，一拖多空调中，第一温度差值大于预设温度差值，即实际过热度比较大时，需要加大系统的冷媒流量，较佳地，可加大内盘管温度高的室内机的冷媒流量，而第一温度差值小于预设温度差值，即实际过热度比较小时，则需减少系统的冷媒流量，较佳地，可缩小内盘管温度低的室内机的冷媒流量，这样，每个室内机所在的区域的温度控制会比较均衡，人 体感觉比较舒服。
当第一温度差值等于预设温度差值时，即实际过热度与目标过热度一致时，系统的冷媒流量不需要增加，但是，可能会有的室内机流经的冷媒流量过多，有的室内机流经的冷媒流量过小，即冷媒分流不均，此时可进行偏流调整，即本公开另一实施例中，可进行偏流调整，具体包括：当第一温度差值等于预设温度差值时，确定每个室内机的环境温度与内盘管温度之间的第二温度差值；当最大第二温度差值与最小第二温度差值之间的相对差值大于设定值时，将最大第二温度差值对应的室内机确定为第三室内机，将最小第二温度差值对应的室内机确定为第四室内机；调整第三室内机对应的第三节流装置的参数，使得第三节流装置中流经的冷媒流量增大，以及调整第四室内机对应的第四节流装置的参数，使得第四节流装置中流经的冷媒流量缩小。
如图1所示，每个室内机中配置有内环温传感器，这样，可通过内环温传感器，获取每个室内机对应的环境温度Tai1、Tai2、…Tain，这样，当Tsh＝Tsh0时，可确定每个室内机的环境温度与内盘管温度之间的第二温度差值，即第二温度差值△Tw1＝Tai1-Tm1，△Tw2＝Tai2-Tm2、…、△Twn＝Tain-Tmn。然后，将最大第二温度差值与最小第二温度差值之间的相对差值与设定值进行比较，当相对差值大于设定值时，可将最大第二温度差值对应的室内机确定为第三室内机，将最小第二温度差值对应的室内机确定为第四室内机；最后，调整第三室内机对应的第三节流装置的参数，使得第三节流装置中流经的冷媒流量增大，以及调整第四室内机对应的第四节流装置的参数，使得第四节流装置中流经的冷媒流量缩小。
例如：△Tw1、△Tw2…、△Twn中，△Tw2最大，△Twn最小，这样，当|△Tw2-△Twn|＞A时，其中，A为大于零的自然数，可根据空调的型号以及运行环境进行设定，可确定冷媒流量分流不均，此时，可将第2个室内机确定为第三室内机，第n个室内机确定为第四室内机，将第2个室内机对应的节流装置2确定为第三节流装置，将第n个室内机对应的节流装置n确定为第四节流装置，调整节流装置2的参数，使得节流装置2中流经的冷媒流量增大，以及调整节流装置n的参数，使得节流装置n中流经的冷媒流量缩小。若节流装置为电子膨胀阀，可将电子膨胀阀2的阀门 开大，较佳地，开阀执行的步数可根据A/2确定。可将电子膨胀阀n的阀门关小，较佳地，关阀执行的步数也可根据A/2确定。
可见，第一温度差值等于预设温度差值时，系统的冷媒流通不需要调整了，但是，可进行偏流调整，进一步提高每个室内机中流量的均衡性，使得每个室内机作用区域的温度比较均衡，进一步提高用户的体验。
当然，本公开实施例中进行冷媒流量控制时，可只进行过热度调整，即根据第一温度差值进行调整，或者，只执行偏流调整，即根据第二温度差值进行调整，或者，既进行过热度调整又进行偏流调整等等，较佳地，可先进行过热度调整再进行偏流调整。
图3是根据一示例性实施例示出的一种空调冷媒流量控制方法的流程图。如图3所示，空调冷媒流量控制的过程包括：
步骤301：获取室外机中压缩机的吸气温度，以及获取每个室内机的内盘管温度。
如图1所示，室外机的压缩机上配置了吸气传感器，从而，可通过吸气传感器获取室外机中压缩机的吸气温度Ts。同样，室内机中配置了内盘管传感器，即可通过内盘管传感器获取每个室内机的内盘管温度，分别为：Tm1、Tm2、…Tmn，即有n个室内机，对应有n个内盘管温度。
步骤302：当吸气温度与内盘管平均温度之间的第一温度差值等于预设温度差值时，确定每个室内机的环境温度与内盘管温度之间的第二温度差值。
已经获取了每个室内机的内盘管温度Tm1、Tm2、…Tmn，可得到内盘管平均温度△Tm，内盘管平均温度为每个内盘管温度求和后的平均值，即△Tm＝(Tm1+Tm2+…+Tmn)/n。获得吸气温度Ts与内盘管平均温度△Tm之间的第一温度差值Tsh，预先配置一个预设温度差值Tsh0，这样，当第一温度差值等于预设温度差值时，此时系统的冷媒流量不需要改变，但是需要进行偏流调整。
如图1所示，每个室内机中配置有内环温传感器，这样，可通过内环温传感器，获取每个室内机对应的环境温度Tai1、Tai2、…Tain，这样，当Tsh＝Tsh0时，可确定每个室内机的环境温度与内盘管温度之间的第二温度差值，即第二温度差值△Tw1＝Tai1-Tm1，△Tw2＝Tai2-Tm2、…、△ Twn＝Tain-Tmn。
步骤303：当最大第二温度差值与最小第二温度差值之间的相对差值大于设定值时，将最大第二温度差值对应的室内机确定为第三室内机，将最小第二温度差值对应的室内机确定为第四室内机。
例如：△Tw1、△Tw2…、△Twn中，△Tw2最大，△Twn最小，这样，当|△Tw2-△Twn|＞A时，其中，A为大于零的自然数，可根据空调的型号以及运行环境进行设定，可确定冷媒流量分流不均，此时，可将第2个室内机确定为第三室内机，第n个室内机确定为第四室内机。
步骤304：调整第三室内机对应的第三节流装置的参数，使得第三节流装置中流经的冷媒流量增大，以及调整第四室内机对应的第四节流装置的参数，使得第四节流装置中流经的冷媒流量缩小。
例如：第2个室内机为第三室内机，第n个室内机为第四室内机。则可将第2个室内机对应的节流装置2确定为第三节流装置，将第n个室内机对应的节流装置n确定为第四节流装置，调整节流装置2的参数，使得节流装置2中流经的冷媒流量增大，以及调整节流装置n的参数，使得节流装置n中流经的冷媒流量缩小。若节流装置为电子膨胀阀，可将电子膨胀阀2的阀门开大，较佳地，开阀执行的步数可根据A/2确定。可将电子膨胀阀n的阀门关小，较佳地，关阀执行的步数也可根据A/2确定。
可见，本实施例中，只需获取室内机的内盘管温度，以及环境温度，就可对室内机流经的冷媒流量进行偏流控制，这样，该空调中的室内机与一拖一空调中的室内机一致，只有环境温度传感器和内盘管温度传感器，而不需要配置蒸发器入口传感器以及蒸发器出口传感器，减少了家用中央空调即一拖多空调中温度传感器，兼容了现有的室内机，实现了一拖一内机与一拖多内机的统一，即提高了一拖多空调的兼容性以及节省了资源。并且，通过偏流控制可进一步提高每个室内机中流量的均衡性，使得每个室内机作用区域的温度比较均衡，进一步提高用户的体验。
当然，本实施例中，进行冷媒流量控制时，不仅可以进行偏流调整，还可进行过热度调整，即根据第一温度差值进行调整，具体可包括：当第一温度差值大于预设温度差值时，调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量增大；当第一温度差值小于预设温度差值时，调 整至少一个节流装置的参数，使得节流装置中流经的冷媒流量缩小。
较佳地，调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量增大包括：将每个内盘管温度与内盘管平均温度进行比较；若当前内盘管温度大于内盘管平均温度，将当前内盘管温度对应的室内机确定为第一室内机；调整第一室内机对应的第一节流装置的参数，使得第一节流装置中流经的冷媒流量增大。
较佳地，调整至少一个节流装置的参数，使得节流装置中流经的冷媒流量缩小包括：将每个内盘管温度与内盘管平均温度进行比较；若当前内盘管温度小于内盘管平均温度，将当前内盘管温度对应的室内机确定为第二室内机；调整第二室内机对应的第二节流装置的参数，使得第二节流装置中流经的冷媒流量缩小。
过热度调整，即根据第一温度差值进行调整的具体过程可与上述实施例一致，不再累述了。
下面将操作流程集合到具体实施例中，举例说明本公开实施例提供的控制方法。
本实施例中，空调包括室外机以及至少两个室内机，每个室内机通过一个对应的电子膨胀阀与室外机连接，空调冷媒流量控制时即可进行过热度调整又可进行偏流调整。保存了预设温度差值Tsh0以及设定值A。

步骤402：判断Tsh＞Tsh0是否成立？若是，执行步骤403，否则，执行步骤407。
其中，内盘管平均温度△Tm＝(Tm1+Tm2+…+Tmn)/n。这样，Tsh＝Ts-△Tm，若Tsh＞Tsh0，确定实际过热度比较高，执行步骤403。
步骤403：确定一个室内机为当前室内机。
可根据预设规则，确定一个室内机为当前室内机。

步骤406：是否所有的室内机都已确定为当前室内机？若是，流程结束，否则，返回步骤403。

第二电子膨胀阀的阀门关小执行的步数，可根据[Tsh-Tsh0]确定。
步骤411：是否所有的室内机都已确定为当前室内机？若是，流程结束，否则，返回步骤408。
步骤412：确定每个室内机的环境温度与内盘管温度之间的第二温度差值。
这里，Tsh＝Tsh0，则可确定每个室内机的环境温度与内盘管温度之间的第二温度差值，即第二温度差值△Tw1＝Tai1-Tm1，△Tw2＝Tai2-Tm2、…、△Twn＝Tain-Tmn。
步骤413：最大第二温度差值与最小第二温度差值之间的相对差值＞A是否成立？若是，执行步骤414，否则，流程结束。
步骤414：将最大第二温度差值对应的室内机确定为第三室内机，将最小第二温度差值对应的室内机确定为第四室内机。
步骤415：将第三室内机对应的第三电子膨胀阀的阀门开大，将第四室 内机对应的第四电子膨胀阀的阀门关小。
较佳地，开阀执行的步数可根据A/2确定，关阀执行的步数也可根据A/2确定。
可见，本实施例中，只需获取室内机的内盘管温度，以及环境温度，就可对室内机流经的冷媒流量进行控制，这样，该空调中的室内机与一拖一空调中的室内机一致，只有环境温度传感器和内盘管温度传感器，而不需要配置蒸发器入口传感器以及蒸发器出口传感器，减少了家用中央空调即一拖多空调中温度传感器，兼容了现有的室内机，实现了一拖一内机与一拖多内机的统一，即提高了一拖多空调的兼容性以及节省了资源。并且，通过过热度控制和偏流控制可进一步提高每个室内机中流量的均衡性，使得每个室内机作用区域的温度比较均衡，进一步提高用户的体验。

    所述第二调整单元，具体用于将每个内盘管温度与所述内盘管平均温度进行比较；若当前内盘管温度小于所述内盘管平均温度，将当前内盘管温度对应的室内机确定为第二室内机；调整所述第二室内机对应的第二节流装置的参数，使得所述第二节流装置中流经的冷媒流量缩小。
  8. 如权利要求5、6或7所述的装置，其特征在于，还包括：
    第三调整单元，用于当所述第一温度差值等于预设温度差值时，确定每个室内机的环境温度与所述内盘管温度之间的第二温度差值；当最大第二温度差值与最小第二温度差值之间的相对差值大于设定值时，将最大第二温度差值对应的室内机确定为第三室内机，将最小第二温度差值对应的 室内机确定为第四室内机；以及，调整所述第三室内机对应的第三节流装置的参数，使得所述第三节流装置中流经的冷媒流量增大，调整所述第四室内机对应的第四节流装置的参数，使得所述第四节流装置中流经的冷媒流量缩小。
  9. 一种空调冷媒流量控制的装置，用于空调，其特征在于，所述空调包括室外机以及至少两个室内机，每个所述室内机通过一个对应的节流装置与所述室外机连接，所述该装置包括：
    处理器；
    用于存储处理器可执行指令的存储器；
    其中，所述处理器被配置为：
    获取所述室外机中压缩机的吸气温度，以及获取每个所述室内机的内盘管温度；
    当所述吸气温度与内盘管平均温度之间的第一温度差值大于预设温度差值时，调整至少一个节流装置的参数，使得所述节流装置中流经的冷媒流量增大，其中，所述内盘管平均温度为每个内盘管温度求和后的平均值；
    当所述第一温度差值小于预设温度差值时，调整至少一个节流装置的参数，使得所述节流装置中流经的冷媒流量缩小。
