其中，多路分流管路2与主流管路1的一端连通。磁性调流件4设置在相邻分流管路2之间，用于遮挡至少一个分流管路2的部分或全部进液端；磁性调流件4与电源连接，被配置为在通电状态下产生磁性。磁体3，设置在分流管路2的外侧，与磁性调流件4的磁性互相吸引或互相排斥。控制器5，与电源51连接，被配置为通过调节电源51输出的电流，控制磁性调流件4的移动，以调节对应分流管路2进液端的进液面积。
本实施例中，磁性调流件4通电后产生磁性，若磁性调流件4在磁体3的引力下移动，则控制电源51使磁性调流件4与磁体3的互相吸引端的磁性不同；若磁性调流件4在磁体3的斥力下移动，则控制电源51使磁性调流件4与磁体3互相排斥端的磁性相同。以图1为例，在磁体3靠近分流管路2侧的磁极为N极的情况下，若磁性调流件4向左侧移动，则控制电源51使磁性调流件4的左端极性为S极，磁性调流件4在磁体3N极的吸引下向左移动；若磁性调流件4向右侧移动，则控制电源51使磁性调流件4的左端极性为N极，磁性调流件4在磁体3N极的排斥力下向右移动。如此，通过磁性调流件4的移动，实现调节分流管路的流量。
采用本公开实施例提供的空调分流器，在相邻分流管路2之间设置磁性调流件4，分流管路2的外侧设置磁体3及控制器5；在多路分流管路的制冷剂流量不均匀 的情况下，控制流量较大的分流管路2对应的磁性调流件4移动，通过磁性调流件4的移动，遮挡对应分流管路2的部分进液端，从而调小对应分流管路2进液端的进液面积，实现制冷剂流量调节，提高分流器分流的均匀性。
在一些情景中，空调分流器并非垂直设置，因制冷剂自身重力的作用，导致分流器分流不均；此时，可能需要调节分流器的部分分流管路的进液量，以使得对多路分流管路的分液更加均匀。在本实施例中，通过磁性调流件4的移动可以实现对一路分流管路2的部分或全部进液端的遮挡，或者同时对两个分流管路的进液端进行部分遮挡等，通过对分流器相邻两条分流管路进液面积的调节，进而对分液情况进行调节，以实现制冷剂分流均匀的目的。
本实施例中，多路分流管路是指包含两路及其以上分流管路2，图1中展示了包含两路分流管路的结构示意图，图2中展示了包含四路分流管路的结构示意图。
可选地，磁性调流件4包括导体42和导线41，其中，导体42设置于相邻分流管路2交汇处；导线41缠绕在导体41的表面，并与电源连接。
本实施例中，磁性调流件4包括导体42和导线41；缠绕在导体41表面的导线通电后，导体42可产生磁性；导体42的磁性取决于导线的缠绕方向和通电电流的方向。在分流管路2为三路以上时，空调分流器包括多个磁性调流件4，当磁性调流件4为两个以上时，基于方便控制的目的，可以将多个磁性调流件4导线41缠绕方向设置为同向。
可选地，磁体3包括两个分别设置在分流管路2两侧的磁性件。
本实施例中，磁体3可以为一个或两个，在分流管路2数量较少的情况下，可以在多路分流管路2的外侧设置一个磁体3；在分流管路2数量较多的情况下，可以在多路分流管路的两侧分别设置一个磁体3，如此，能够保证磁体3与磁性调流件4的作用力，提高控制效果。此外，在分流管路2两侧分别设置磁体3时，两个磁体3靠近分流管路2侧的极性可以相同或者不同；极性不同时，更加有助于控制磁性调流件4的移动。图1中展示了分流管路一侧设置磁体的结构示意图，图2中展示了分流管路两侧设置不同极性磁体的结构示意图。由图中可知，磁体3具有N极和S极两个磁极，将磁体3的N极或S极设置于分流管路2的一侧，即磁体3的一个磁极靠近分流管路2；这样，有助于增强磁体3与磁性调流件4的相互作用力。
本实施例的空调分流器，根据导线41缠绕方向和通电电流方向；控制磁性调 流件4的磁性，进而控制磁性调流件4移动，调节分流管路2进液端的进液面积，实现制冷剂流量调节，提高分流器分流的均匀性。
结合图4所示，本公开实施例提供一种用于空调分流器的控制方法，包括：
S101，获取多路分流管路出液端的制冷剂流量，并确定流量超标的目标分流管路。
本实施例中，可以在每路分流管路的出液端分别设置流量传感器或流量计，用于获取每路分流管路出液端的制冷剂流量。可以通过设置标定值的方式，确定流量超标的目标分流管路；或者，可以通过比较的方式，获取流量最大的分流管路，即确定流量超标的目标分流管路。
S102，控制目标分流管路对应的磁性调流件移动，以调节目标分流管路进液端的进液面积。
本实施例中，确定目标分流管路后，即可控制目标分流管路对应的磁性调流件移动。具体控制过程为：确定磁性调流件，进而明确了磁性调流件的移动方向；基于分流管路外侧磁体的磁性，确定磁性调流件的磁性；结合磁性调流件中导线缠绕方向及电源电流方向，使磁性调流件产生相应的磁性；如此，通过目标分流管路对应的磁性调流件的移动，实现对分流管路的部分进液端的遮挡，以达到调节目标分流管路进液面积的调节，改善分流管路流量不均匀的问题。以图1为例进行说明，假设控制图1左边路的分流管路为目标管路，则需控制对应的磁性调流件向左移动，以调节该分流管路的进液面积；此时，磁体靠近分流管路侧的磁性为N极，磁性调流件通电后，磁性调流件导体的左端需为S极，根据导向缠绕方向确定电源的电流方向，使磁性调流件产生左端为S极的磁性，与磁体互相吸引，实现磁性调流件的移动。
这里，磁性调流件的确定，可以通过目标分流管路的位置确定；例如：当目标分流管路在边路时，目标分流管路对应的磁性调流件只有一个，磁性调流件明确；当目标分流管路在非边路时，目标分流管路对应的磁性调流件可能有两个，此时可根据实际情况或预设条件确定其中一个磁性调流件进行控制；预设条件可以是控制左侧或右侧的磁性调流件，或者，可以是根据磁性调流件与磁体的距离远近确定磁性调流件。
此外，可以通过控制磁性调流件的移动距离，实现对目标分流管路进液面积的调节；或者，可以通过控制磁性调流件的通电时长，实现对目标分流管路进液面积 的调节。
采用本公开实施例提供的用于空调分流器的控制方法，基于电磁感应原理，控制通电可产生磁性的磁性调流件移动，从而改变目标分流管路进液面积的大小，如此，实现分流器制冷剂流量的调节，提高了分离器分流的均匀性。
可选地，控制目标分流管路对应的磁性调流件移动，包括控制电源输出的电流，调节磁性调流件移动距离。
本实施例中，电源输出电流的大小和时长，影响磁性调流件的磁场大小，从而影响磁性调流的移动速度，导致单位时间内磁性调流件的移动距离不同。因此，调节目标分流管路的进液面积，可以根据控制电源输出的电流，控制磁性调流件的移动距离实现。
可选地，根据磁性调流件的通电时长，和/或，电流大小，确定目标分流管路对应的磁性调流件的移动距离。
本实施例中，磁性调流件的通电时长反映了磁性调流件产生磁性的时长。磁性调流件具有磁性，是磁性调流件移动的前提条件；因此，在通电电流不变的情况下，磁性调流件的通电时长决定了磁性调流件的移动距离。
磁性调流件通电电流的大小反映了磁性调流件产生磁性的强弱，电流越大，磁性调流件的磁场越强；在通电时间不变的情况下，电流越大，磁性调流件移动速度越快，从而影响磁性调流件的移动距离。
结合图5所示，本公开实施例提供另一种用于空调分流器的控制方法，包括：
S201，获取多路分流管路出液端的制冷剂流量，根据分流管路的数量，确定流量标量。
本实施例中，流量标量是指判断每路分流管路的流量大小的一个标定值，如，将每路分流管路的流量与流量标量比较，若流量值大于流量标量，则认为该分流管路的流量超标。通常，根据分流管路的数量和总流量，获取流量标量，即流量标量＝总流量/分流管路数量；其中，总流量可以通过检测主流管路流量获得，或者可以通过累计多个分流管路的流量之和获得。
S202，判断分流管路出液端的制冷剂流量与流量标量的差值是否满足超标条件。
S203，如果满足，则确定多路分流管路中流量最大的分流管路为目标分流管路。
本实施例中，超标条件可以是设定值，也可以是设定区间；例如，分流管路出 液端的制冷剂流量与流量标量的差值为非零值，即超标条件为分流管路的流量与流量标量大小不相等；或者，分流管路出液端的制冷剂流量与流量标量的差值大于设定阈值，即超标条件为分流管路的流量与流量标量大小不相等，且差值大于设定阈值。
在确定满足超标条件的分流管路后，如果满足超标条件的分流管路数量为一个，则该分流管路为目标分流管路；如果满足超标条件的分流管路数量为两个以上，则确认满足超标条件的分流管路中流量最大的分流管路为目标分流管路。
可选地，超标条件是根据分流管路的数量确定的；在分流管路的数量为2时，超标条件是分流管路出液端的制冷剂流量与流量标量的差值不为零；在分流管路的数量大于2时，超标条件是分流管路出液端的制冷剂流量与流量标量差值大于设定阈值。
本实施例中，超标条件的设定依据是分流管路的数量；在分流管路数量为2时，超标条件是分流管路的流量与流量标量的差值不为零，即判断分流器分流是否均匀，根据分流管路的流量与流量标量的差值，存在差值的时候，说明两路分流管路的流量大小不同，分流器分流不均匀。此外，在分流管路数量为2时，还可以直接比较两路分流管路的流量大小，判断分流器分流是否均匀，无需根据流量标量和超标条件判断。
在分流管路数量大于2时，超标条件是分流管路的流量与流量标量的差值大于设定阈值；即在分流管路数量较多时，分流器分流是否均匀是指每路分流管路的流量变化量是否在设定范围内，如果超过设定范围，则判定分流器分流不均匀；因此，在分流管路数量较多时，超标条件可以是一个设定范围，不局限于一个定值。
S204，控制目标分流管路对应的磁性调流件移动，以调节目标分流管路进液端的进液面积。
可选地，控制目标分流管路对应的磁性调流件移动包括：在目标分流管路的一侧设置有磁性调流件的情况下，控制磁性调流件移动；在目标分流管路的两侧均设置有磁性调流件的情况下，控制任一磁性调流件移动，或，控制与磁体距离最近的磁性调流件移动。
本实施例中，如果只在目标分流管路的一侧设置有磁性调流件，则目标分流管路对应的磁性调流件唯一，控制该磁性调流件移动即可。如果目标分流管路两侧均设置有磁性调流件，则可以根据磁性调流件与磁体的距离远近，选择控制距离最近 的磁性调流件移动，如此，有助于保证磁体与磁性调流件的作用力，提高调节效果；或者，在分流管路两侧均设有磁体情况下，还可以随机选取控制目标分流管路对应的一个磁性调流件；或者，可以控制目标分流管路固定方向侧(如左侧)的磁性调流件。如此，可以灵活选取磁性调流件，且保证了控制效果。
