具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其 他实施例，都属于本申请保护的范围。
电子膨胀阀属于空调中非常重要的一个配件，如果发生故障或出现其它异常状态，将直接影响空调的启动和运行。针对现有技术中空调电子膨胀阀在空调上电后，复位时间比较长，影响空调压机的启动时间，使得制冷制热相应地启动缓慢，本申请提出新的空调电子膨胀阀的复位方法，以提高复位时间。
图1是本申请提供的空调电子膨胀阀复位方法的流程示意图之一，如图1所示，包括：
步骤100：获取电子膨胀阀在异常断电后的阀开度位置步数值；
步骤200：基于双基准位置值与所述阀开度位置步数值之间的比较值，将所述电子膨胀阀复位至初始阀开度位置。
通常，电子膨胀阀在空调异常停机，即异常断电后，会停留在某个开度位置，可记录对应的阀开度位置步数值。可以理解的是，空调在正常关机状态时，不会停留在上述某个开度位置，待下次开机后再正常进行复位。因此，本申请针对的场景是空调异常断电下的
本申请设置两个基准位置值，即双基准位置值，同时和阀开度位置步数值进行对比，分别比较两个基准值到阀开度位置步数值的距离，结合设置的复位方式，使电子膨胀阀能快速复位到系统设定的初始阀开度位置。这个的初始阀开度位置值，是指在空调系统刚开机时刻，电子膨胀阀预设值的大小，可以理解为使空调达到最佳工况所对应的电子膨胀阀所处的位置值。
需要说明的是，空调电子膨胀阀作为空调重要部件之一，其作用包括：
1、调节流量：可以结合制冷节的过热程度，来决定阀门的开度多少，从而有效的调节进入到蒸发器内的制冷剂量有多少，让铜管内部的冷媒和蒸发器内部的热负荷能够匹配。当蒸发器的热量出现增加的情况，这时电子膨胀阀会增加其开度，制冷剂的流量也就会随之增加。相反，制冷剂的流量聚会出现减少。
2、控制过热度：可以有效的控制蒸发器出气口的制冷剂产生过热的现象，从而确保蒸发器的传热面积能够被充分的使用，还可以避免在吸气的过程中，产生的液体撞击压缩机，而出现损坏的情况。这样可以更好的 保护空调压缩机，增加使用寿命。
3、节流降压：可将常温状态的高压制冷剂液体，转化成低温且抵压的液体，同时会有少许的闪发气体产生。通过降低压力的方法，达到向外界吸收热量的性能，这样能够精确到吸收的室内热量，满足空调的使用需求。
4、控制蒸发液位：若是带液位控制的空调，则膨胀阀还可以起到控制液位的性能，这样不但能够确保传热面积得到充分的使用，还可以避免在吸气的时候，导致带液影响到吸气的过热度，影响到正常的使用，确保了后期正常的使用。
本申请通过在空调的电子膨胀阀设置的两个预设基准位值，综合判断电子膨胀阀异常断电后的位置与两个预设基准位值之间的相对位置关系，节省了复位时间，加快空调压机启动时间，提升制冷制热速度，有效提升用户体验。
在上述实施例的基础上，所述获取电子膨胀阀在异常断电后的阀开度位置步数值之前，还包括：
待所述电子膨胀阀初始上电复位时，获取所述双基准位置值，所述双基准位置值包括0基准位置值和最大基准位置值。
具体地，在空调系统初始上电复位时，读取预留数据，获取双基准位置值，包括最小的0基准位置值，以及最大基准位置值。这里只有在系统初始上电复位后读取是最准确的，后续待系统运行后断电、上电再读取，会由于各种不确定因素，导致读取的数据存在偏差。
可以理解的是，在系统初始化时，需要读取电子膨胀阀在运行过程中的两个极值，最小值即0基准位置值，最大值即最大基准位置值，电子膨胀阀即在这两个极值之间运动，然后复位至初始阀开度位置。
本申请通过在系统初始上电状态时，读取电子膨胀阀对应的双基准位置值，为后续异常断电状态时，电子膨胀阀的复位计算提供参考依据。
在上述实施例的基础上，所述获取电子膨胀阀在异常断电后的阀开度位置步数值，包括：
在异常断电后，以预设间隔获取及更新所述阀开度位置步数值。
具体地，空调出现异常断电时，属于空调常见的EF故障之一，这时 的电子膨胀阀会停留在某个开度位置，通常也会有微小的位移。
首先记录电子膨胀阀的阀开度位置步数值，记为Fa，然后以预设间隔记录更新一次，可设为0.5s，直到下次上电复位开启。
本申请通过实时记录电子膨胀阀在空调异常断电后的位置值，在下次正常通上之前，系统将获取到准确的位置值，结合双基准位置值，能快速计算出复位行程，实现快速复位的效果。
在上述实施例的基础上，所述基于双基准位置值与所述阀开度位置步数值之间的比较值，将所述电子膨胀阀复位至初始阀开度位置，包括：
若确定所述阀开度位置步数值为0，则使所述电子膨胀阀运行至所述最大基准位置值之后，运行至所述初始阀开度位置。
可选地，针对读取的阀开度位置步数值为0的情况，系统设置的复位行程为：
使电子膨胀阀运行至最大基准位置值Fmax之后，再运行至初始阀开度位置，这里是让电子膨胀阀离开当前的0值位置，整体运行至最远的最大基准位置值之后，再回到初始阀开度位置，而不是运行至0基准位置值，是避免电子膨胀阀当前的0值位置和0基准位置值之间距离过近，电子膨胀阀运行距离不足，容易出现异常。该流程在图2中对应第一个判断分支。
本申请考虑了电子膨胀阀的阀开度位置步数值为0时，使电子膨胀阀运行最大距离，实现充分复位的效果。
在上述实施例的基础上，所述基于双基准位置值与所述阀开度位置步数值之间的比较值，将所述电子膨胀阀复位至初始阀开度位置，还包括：
若确定所述阀开度位置步数值不为0，则分别获取所述阀开度位置步数值与所述0基准位置值的第一绝对差值，以及所述阀开度位置步数值与所述最大基准位置值的第二绝对差值；
比较获取所述第一绝对差值和所述第二绝对差值的相对差值，基于所述相对差值，确定所述电子膨胀阀到所述初始阀开度位置的复位行程。
其中，所述比较获取所述第一绝对差值和所述第二绝对差值的相对差值，基于所述相对差值，确定所述电子膨胀阀到所述初始阀开度位置的复位行程，包括：
若确定所述相对差值大于0，则使所述电子膨胀阀运行至所述最大基 准位置值之后，运行至所述初始阀开度位置；
若确定所述相对差值小于0，则使所述电子膨胀阀运行至所述0基准位置值之后，运行至所述初始阀开度位置。
具体地，针对读取的阀开度位置步数值不为0的情况，系统设置的复位行程为：
分别计算阀开度位置步数值与0基准位置值、以及最大基准位置值之差的绝对值，即第一绝对差值|Fa-0|和第二绝对差值|Fa-Fmax|；
若第一绝对差值大于第二绝对差值，则说明阀开度位置步数值是靠近最大基准位置值，此时，使电子膨胀阀运行至最大基准位置值之后，运行至初始阀开度位置；
否则，若第一绝对差值小于第二绝对差值，则说明阀开度位置步数值是靠近0基准位置值，此时，使电子膨胀阀运行至0基准位置值之后，运行至初始阀开度位置。
上述根据阀开度位置步数值与双基准位置值之间的相对位置关系，选择较近的一端作为电子膨胀阀复位运行的行程，能缩短复位时间，对应于图2中的第二个判断分支。
本申请通过比较阀开度位置步数值与双基准位置值之间的相对位置，选择靠近阀开度位置步数值的一端进行复位，具有设置灵活，方便实现快速复位的效果。
