技术领域
本申请涉及空气调节技术领域，例如涉及一种调试组件。
背景技术
目前，现有定频空调器大多使用毛细管或者节流短管作为空调系统的节流部件，研发人员在研发初期需要通过多次测试才能确定毛细管参数或者节流短管规格，从而确定空调系统最终性能。测试过程中可通过更改毛细管尺寸实现不同的毛细管参数，或者更换节流阀芯改变节流短管的节流参数。另外，当更改毛细管尺寸或更换节流阀芯时均需要重新抽真空后测试。多次抽真空需要花费大量时间。

具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，一个或多个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
本公开实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开实施例的实施例。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。
本公开实施例中，术语“上”、“下”、“内”、“中”、“外”、“前”、“后”等指示的方位或位置关系为基于附图所示的方位或位置关系。这些术语主要是为了更好地描述本公开实施例及其实施例，并非用于限定所指示的装置、元件或组成部分必须具有特定方位，或以特定方位进行构造和操作。并且，上述部分术语除了可以用于表示方位或位置关系以外，还可能用于表示其他含义，例如术语“上”在某些情况下也可能用于表示某种依附关系或连接关系。对于本领域普通技术人员而言，可以根据具体情况理解这些术语在本公开实施例中的具体含义。
另外，术语“设置”、“连接”、“固定”应做广义理解。例如，“连接”可以是固定连接，可拆卸连接，或整体式构造；可以是机械连接，或电连接；可以是直接相连，或者是通过中间媒介间接相连，又或者是两个装置、元件或组成部分之间内部的连通。对于本领域普通技术人员而言，可以根据具体情况理解上述术语在本公开实施例中的具体含义。

术语“和/或”是一种描述对象的关联关系，表示可以存在三种关系。例如，A和/或B，表示：A或B，或，A和B这三种关系。
需要说明的是，在不冲突的情况下，本公开实施例中的实施例及实施例中的特征可以相互组合。
结合图1至图3所示，本公开实施例提供一种调试组件，包括用于连通室内机管路的第一主干管路10、用于连通室外机管路的第二主干管路20和支干管路30，支干管路30连通第一主干管路10和第二主干管路20，支干管路30设置有节流组件和开关阀50，开关阀50被配置为控制支干管路30的通断；其中，支干管路30为多条，多条支干管路30中节流组件的节流参数部分相同。
采用上述实施例，在测试过程中，一次抽真空，利用多条支干管路进行多组不同节流组件的节流参数的试验，在任一一条支干管路测试过程中，其他支干管路通过开关阀关闭，防止干扰待测试的支干管路的测试结果；减少了抽真空的次数，从而缩短了测试周期，提高了测试效率。
本公开实施例中支干管路的条数大于2条，对具体条数不作限定。测试过程中，抽真空的次数与支干管路的条数成反比。在支干管路条数越多的情况下，节流组件的节流参数可选择的范围越大，有利于提高测试精度。
节流组件的节流参数可包括节流组件的长度、节流组件的流通面积、节流组件的孔径或节流组件的压差中的一个或多个。在实际应用中，节流组件的长度不同，节流效果不同。同理，节流组件的流通面积或孔径不同，节流效果不同。节流组件的压差由节流组件两端或内部形成，通过压差实现节流目的。其中，压差越大，节流效果越显著。
可选地，节流组件与支干管路可拆卸连接。根据空调不同的匹数，更换相适应的节流组件，这样，有利于提高调试组件的适应范围。可选地，节流组件可为毛细管、电子膨胀阀、节流阀或节流孔板。
可选地，开关阀设置于节流组件与第二主干管路之间的支干管路中。这样，在更换待测试的支干管路的情况下，通过开关阀停止正在测试的支干管路的流通，阻止已通过节流组件的冷媒继续流向第二主干管路，降低对待测试的支干管路的测试结果的影响。
在实际应用中，第一主干管路与室内机的带喇叭口的细管连通，第二主干管路与室外机的二通阀连通。其中，第一主干管路设有控制第一主干管路通断的开关。在测试过程中，在更换待测试的支干管路的情况下，通过开关断开第一主干管路内的流路，通过开关阀断开正在测试的支干管路内的流路，然后打开待测试的支干管路的流路，支干管路更换完毕后，通过开关打开第一主干管路的流路，冷媒流经支干管路进行节流测试。结合图1所示，调试组件包括4条支干管路。在一次抽真空的情况下，通过4条支干管路可进行4组节流测试。在进行4组节流测试的情况下，节省了3次抽真空的次数，缩短了测试周期，提高 了测试效率。另外，选择4条支干管路并联设置，有利于调试组件的拆装。
可选地，支干管路30包括第一支路301、第二支路303和连接管路302，第一支路301连通第一主干管路10；第二支路303连通第二主干管路20；连接管路302连通第一支路301和第二支路303；其中，连接管路302设有节流组件。这样，通过第一支路、第二支路和连接管路，有利于支干管路的拆装及维护。另外，有利于节流组件和支干管路的拆装。在需要更换节流组件的情况下，只需拆卸连接管路，第一支路和第一主干管路、第二支路和第二主干管路的连接保持不动。这样，有利于防止支干管路与第一主干管路和第二主干管路多次拆卸后，降低连接牢固度及连接处的气密性。
第一支路和连接管路可拆卸连接，例如，第一支路与连接管路螺纹连接。第一支路与第一主干管路可拆卸连接。其中，多个第一支路与第一主干管路可通过多通阀连通。第二支路和连接管路可拆卸连接，例如，第二支路与连接管路螺纹连接。第二支路与第二主干管路可拆卸连接。其中，多个第二支路与第二主干管路可通过多通阀连通。
节流组件设置于连接管路内。节流组件与连接管路可拆卸连接。这样，有利于节流组件的拆装。
本公开实施例中管路的连接处均设有密封圈或密封装置。这样，有利于提高测试过程中调试组件的气密性，保持真空状态。
可选地，节流组件包括相对设置的第一节流元件401和第二节流元件402。在制冷或制热的过程中，冷媒的流向是相反的。通过第一节流元件和第二节流元件实现在制冷或制热过程中对冷媒的节流目的。其中，在第一节流元件和第二节流元件的节流参数相同的情况下，在制冷或制热过程中，冷媒流经支干管路的节流结果相同。在第一节流元件和第二节流元件的节流参数不同的情况下，在制冷场景下冷媒流经支干管路的节流结果与在制热场景下冷媒流经支干管路的节流结果不同。
在制冷的情况下，冷媒由第一主干管路流向第二主干管路，通过第二节流元件实现节流的目的；在制热的情况下，冷媒由第二主干管路流向第一主干管路，通过第一节流元件实现节流的目的。通过节流参数不同的第二节流元件和第一节流元件分别对制冷和制热场景下的冷媒进行节流测试，无需根据不同的应用场景更换不同参数的节流元件，缩短了测试周期，提高了测试的准确度。
第一节流元件和第二节流元件通过相对设置，保证在制冷时只有第二节流元件起节流作用，在制热时只有第一节流元件起节流作用。例如，在制冷的情况下，第二节流元件的进口朝向第一支路方向设置，冷媒流动冲击产生的冲击力将第二节流元件卡固在连接管路内，第二节流元件与连接管路相配合起到节流作用；此时第一节流元件则不起节流作用。在制热的情况下，第一节流元件的进口朝向第二支路方向设置，冷媒流动冲击产生的冲击力将第一节流元件卡固在连接管路内，第一节流元件与连接管路相配合起到节流作用；此时第二节流元件则不起节流作用。
可选地，每一节流元件与连接管路均可拆卸连接。这样，有利于连接管路与节流元件 的拆装，便于根据空调匹数，更换不同节流参数的节流元件，提高了调试组件的适应范围。
每一节流元件均插装于连接管路内，且与连接管路可拆卸连接。可选地，连接管路包括第一段管路和第二段管路，第一节流元件设置于第一段管路内，第二节流元件设置于第二段管路内，第一段管路和第二段管路可拆卸连接。这样，有利于第一节流元件和第二节流元件的拆装。例如，在需更换第一节流元件或第二节流元件的情况下，只需将第一段管路和第二段管路拆卸，然后更换相应的节流元件即可，方便快捷，省时省力。
可选地，每一节流元件的外侧壁均设有限位部403，限位部403自节流元件的外侧壁向外凸出至连接管路302的内侧壁；其中，连接管路302的内侧壁设有与限位部403相适配的卡槽(图中未示出)。这样，通过限位部实现节流元件的定位，保证节流元件的正向安装，确保对冷媒起到相应的节流作用。限位部与连接管路的内侧壁的卡槽相配合，实现节流元件和连接管路的卡接固定。
结合图2和图3所示，节流元件呈柱状。可选地，限位部呈长方体状、翅片状或条状。多个限位部沿节流元件的外侧壁间隔均匀布设。限位部的长度小于节流元件的长度。可选地，限位部包括相对的第一端和第二端，第一端和第二端的轴线与节流元件的轴线相平行。可选地，限位部的第一端靠近节流元件的端面。可选地，限位部的第一端与节流元件的端面位于同一个平面。可选地，限位部的第二端为一斜面。这样，使得限位部与卡槽卡接更加顺畅，减少卡接时的冲击力。
可选地，结合图3所示，一限位部403的顶部边缘设有凸起4031。其中，凸起靠近节流元件端面。这样，有助于帮助用户识别节流元件的安装方向，防止反向安装。
可选地，限位部与节流元件可一体成型。这样，在冷媒流动冲击产生的冲击力作用于限位部及节流元件的情况下，一体成型的结构，有助于提高限位部与节流元件连接的牢固度。
可选地，每一节流元件内均设有用于节流的通孔404。这样，冷媒流经通孔进行节流，不同的孔径，节流效果不同。另外，通孔加工制造简单，降低了加工成本。此外，便于更换不同孔径的节流元件。
可选地，每一节流元件内设有一个或多个通孔。可选地，多个通孔均布于节流元件中。这样，通过多个通孔，有助于降低冷媒对节流元件的冲击力。节流元件的节流参数为多个通孔的流通面积的叠加。
可选地，通孔的进口呈喇叭状。可选地，通孔的出口呈喇叭状。这样，有利于减少冷媒对节流元件的冲击力。
可选地，开关阀50连通连接管路302和第二支路303。这样，通过开关阀断开节流组件与第二支路之间的流路。防止在更换支干管路的过程中，流经节流组件的部分冷媒在节流作用下依旧向第二支路和第二主干管路流通，影响另一支干管路的测试结果。可选地，开关阀可为二通阀。二通阀的一个阀口与连接管路连通，另一个阀口与第二支路连通。
可选地，开关阀与连接管路可拆卸连接。可选地，开关阀与第二支路可拆卸连接。这 样，有利于开关阀的拆装。
可选地，开关阀上设有安装板。安装板套设于开关阀并靠近一阀口。安装板上设有安装孔。这样，在实际应用过程中，可通过安装板将调试组件进行固定，防止测试过程中冷媒的冲击力过大，调试组件振动，导致调试组件中管路的连接处出现松动，造成不必要的损失。
可选地，调试组件还包括：第一分液器60，连通第一支路301和第一主干管路10，和/或，第二分液器70，连通第二支路303和第二主干管路20。这样，有助于汇集多条第一支路的流路，同时对第一主干管路和第二主干管路的流路进行分流。通过设置第一分液器和第二分液器，使得调试组件外观整洁。
在冷媒由支干管路流向第一主干管路的情况下，通过第一分液器将来自多个支干管路的多条流路汇集为一条流路，该流路进入第一主干管路。在冷媒由第一主干管路流向支干管路的情况下，通过第一分液器将第一主干管路的流路分流，分流后的多条流路分别进入相应的支干管路。
在冷媒由支干管路流向第二主干管路的情况下，通过第二分液器将来自多个支干管路的多条流路汇集为一条流路，该流路进入第二主干管路。在冷媒由第二主干管路流向支干管路的情况下，通过第二分液器将第二主干管路的流路分流，分流后的多条流路分别进入相应的支干管路。
结合图1所示，第一分液器包括一个主干口和四个分口。第二分液器包括一个主干口和四个分口。在实际应用中，第一分液器的分口数量小于或等于支干管路的数量。第二分液器的分口数量小于或等于支干管路的数量。这样，在第一分液器的分口数量小于支干管路的情况下，第一分液器中未与支干管路连通的分口堵塞不通即可。同理，在第二分液器的分口数量小于支干管路的情况下，第二分液器中未与支干管路连通的分口堵塞不通即可。
可选地，第一支路301为弯管，和/或，第二支路303为弯管。这样，有利于扩大多条支干管路的间隔距离，便于支干管路、节流组件的拆装。
可选地，第一支路可呈Z型、S型或L型。在第一支路和第一主干管路装配的情况下，多条第一支路均匀布设，且相邻第一支路之间的间距为最大值。可选地，多条第一支路互不干涉。结合图1所示。
可选地，第二支路可呈Z型、S型或L型。这样，能够更好地将多条第二支路中的流路汇集至第二主干管路。
可选地，第一主干管路10设有二通阀80，二通阀80设置于第一分液器60的主干口。这样，通过二通阀控制第一主干管路的通断。二通阀的一阀口与第一分液器的主干口连通，另一阀口与室内机的带喇叭口的细管连通。在测试过程中，在更换待测试的支干管路的情况下，通过二通阀断开第一主干管路内的流路，通过开关阀断开正在测试的支干管路内的流路，然后打开另一待测试的支干管路的流路，支干管路更换完毕后，通过二通阀打开第 一主干管路的流路，冷媒从第一主干管路流出至支干管路进行节流测试。
