具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例的压缩机组件。
如图1至图3所示，本公开实施例的压缩机组件包括第一压缩机1、第二压缩机2、 第一油分离器3、第二油分离器4、存储容器5、气液分离器6、液平衡管7和气平衡管8。
第一压缩机1具有第一排气口101和第一回气口102，第二压缩机2具有第二排气口201和第二回气口202。第一油分离器3具有第一出油口302和与第一排气口101连通的第一油分进口301，第二油分离器4具有第二出油口402和与第二排气口201连通的第二油分进口401。
存储容器5具有容纳腔5011和与容纳腔5011连通的制冷剂进口(第一制冷剂进口5021、第二制冷剂进口5031)。第一出油口302和第二出油口402中的每一者与制冷剂进口连通。气液分离器6具有分离腔6011以及与分离腔6011连通的第一气分出口6021、第二气分出口6031、第一回油孔6022和第二回油孔6032。第一气分出口6021和第一回油孔6022中的每一者与第一回气口102连通，第二气分出口6031和第二回油孔6032中的每一者与第二回气口202连通。
气平衡管8位于液平衡管7的上方，本领域技术人员可以理解的是，此处所描述的气平衡管8位于液平衡管7的上方是指，当存储容器5和气液分离器6处于使用状态时，气平衡管8位于液平衡管7的上方。
液平衡管7的一端和气平衡管8的一端中的每一者与容纳腔5011连通，液平衡管7的另一端和气平衡管8的另一端中的每一者与分离腔6011连通。例如，如图1至图3所示，液平衡管7具有在其长度方向上相对的第一端701和第二端702，气平衡管8具有在其长度方向上相对的第三端801和第四端802.第一端701和第三端801中的每一者与容纳腔5011连通，第二端702和第四端802中的每一者与分离腔6011连通。
由此，利用液平衡管7和气平衡管8可以实现容纳腔5011和分离腔6011的连通，实现容纳腔5011和分离腔6011之间的液平衡和气平衡，从而容纳腔5011内的气态物质可以通过气平衡管8进入分离腔6011，容纳腔5011内的液态物质可以通过液平衡管7进入分离腔6011。
本公开实施例的压缩机组件运行时，从第一压缩机1的第一排气口101流出的含有冷冻油的制冷剂蒸汽(第一含油制冷剂蒸汽)经第一油分进口301进入第一油分离器3，该第一含油制冷剂蒸汽在第一油分离器3内分离为第一制冷剂蒸汽和第一冷冻油。该第一冷冻油经第一出油口302和制冷剂进口进入存储容器5的容纳腔5011内，该第一制冷剂蒸汽进入室内换热器进行换热。同时，从第二压缩机2的第二排气口201流出的含有冷冻油的制冷剂蒸汽(第二含油制冷剂蒸汽)经第二油分进口401进入第二油分离器4，该第二含油制冷剂蒸汽在第二油分离器4内分离为第二制冷剂蒸汽和第二冷冻油。该第二冷冻油经第二出油口402和制冷剂进口进入存储容器5的容纳腔5011内，该第二制冷剂蒸汽进入室内换热器进行换热。
此外，从室内换热器流出的、需要返回第一压缩机1和第二压缩机2中的一部分制冷剂(第三制冷剂)，经制冷剂进口进入存储容器5的容纳腔5011内，从室内换热器流出的、需要返回第一压缩机1和第二压缩机2中的另一部分制冷剂(第二制冷剂)， 经制冷剂进口进入存储容器5的容纳腔5011内。
接着，在第一压缩机1吸气(第三制冷剂和第四制冷剂)过程中，分离腔6011内的冷冻油能够经第一回油孔6022、第一气分出口6021和第一回气口102返回第一压缩机1内；在第二压缩机2吸气(第三制冷剂和第四制冷剂)过程中，分离腔6011内的一部分冷冻油能够经第二回油孔6032、第二气分出口6031和第二回气口202返回第二压缩机2内。从而实现第一压缩机1和第二压缩机2的冷冻油的回收。
对于通过气液分离器回油的压缩机组件，其压缩机的回油量与压缩机的吸气量存在以下关系：压缩机的回油量随压缩机的吸气量增加而增加，压缩机的回油量随压缩机的吸气量减少而减少。由此，当不同容量的压缩机用于同一系统中时，若不同容量的压缩机吸气量偏差太大(超过设计偏差)，则在压缩机吸气过程随制冷剂蒸汽返回该压缩机的冷冻油量偏差也会较大，导致部分压缩机(通常是容量小的压缩机)存在回油不足甚至无法回油的问题，导致压缩机运行可靠性差。
本公开实施例的压缩机组件，由于第一冷冻油、第二冷冻油、第三制冷剂和第四制冷剂均先进入存储容器5的容纳腔5011内，再通过液平衡管7和气平衡管8进入气液分离器6的分离腔6011内，因此，可以保证第一回油孔6022和第二回油孔6032所在的分离腔6011内具有冷冻油和制冷剂，且第一回油孔6022和第二回油孔6032所处的环境压强相当。从而可以减少甚至避免因第一压缩机1和第二压缩机2的容量不同，引起的第一压缩机1和第二压缩机2的制冷剂分配偏差大(与大容量的压缩机对应的气液分离器的气分进口处的制冷剂极多，与小容量的压缩机对应的气液分离器的气分进口处的制冷剂极少)。进而可以减少甚至避免因第一压缩机1和第二压缩机2的容量不同，引起的小容量压缩机回油不足甚至无法回油的问题。避免压缩机因回油不及时、或无法回油导致的压缩机因缺少润滑而磨损，极大地提升了压缩机组件的可靠性。
因此，本公开实施例的压缩机组件具有可靠性高等优点。
此外，本公开实施例的存储容器5可以存储多余的制冷剂和冷冻油，气液分离器6除了可以存储多余的制冷剂和冷冻油，还可以实现压缩机的回油。
在本公开的实施例中，存储容器可以为气液分离器，容纳腔可以为分离腔。
例如，存储容器为第一气液分离器，气液分离器为第二气液分离器，由此，进入第一气液分离器内的制冷剂可以利用第一气液分离器实现第一次气液分离，之后再进入第二气液分离器，并在第二气液分离器内进行第二次气液分离。该第一气液分离器除了实现气液分离作用，还可以存储多余的制冷剂和冷冻油；该第二气液分离器除了实现气液分离作用、存储多余的制冷剂和冷冻油，还可以实现压缩机的回油。
在本公开的实施例中，如图1和图2所示，压缩机组件包括第一管11、第二管12、第三管13、第四管14、第五管15和第六管16。其中，第一排气口101与第一油分进口301通过第一管11连通，第二排气口201与第二油分进口401通过第二管12连通。第一出油口302与制冷剂进口通过第五管15连通，第二出油口402与制冷剂进口通过第六管16连通。第一气分出口5021与第一回气口102通过第三管13连通，第二气分出 口6021与第二回气口202通过第四管14连通。
在一些实施例中，存储容器5包括壳体501，壳体501限定出容纳腔5011。
气液分离器6包括筒体601、第一出气管602和第二出气管603，筒体601限定出分离腔6011。第一出气管602的一部分和第二出气管603的一部分中的每一者伸入到分离腔6011内。第一回油孔6022设在第一出气管602的一部分，第一气分出口6021设在第一出气管602的另一部分，第二回油孔6032设在第二出气管603的一部分，第二气分出口6031设在第二出气管603的另一部分。
例如，第一出气管602包括第一部分和第二部分，该第一部分伸入到分离腔6011内，该第二部分位于分离腔6011外。第一回油孔6022设在第一出气管602的第一部分，第一气分出口6021设在第一出气管602的第二部分。
第二出气管603包括第一部分和第二部分，该第一部分伸入到分离腔6011内，该第二部分位于分离腔6011外。第二回油孔6032设在第二出气管603的第一部分，第二气分出口6031设在出气管603的第二部分。
液平衡管7的一端位于第一回油孔6022的下方或者液平衡管7的一端和第一回油孔6022位于同一高度；液平衡管7的一端位于第二回油孔6032的下方或者液平衡管7的一端和第二回油孔6032位于同一高度。液平衡管7的另一端位于第一回油孔6022的下方或者液平衡管7的另一端和第一回油孔6022位于同一高度；液平衡管7的另一端位于第二回油孔6032的下方或者液平衡管7的另一端和第二回油孔6032位于同一高度。
本领域技术人员可以理解的是，当存储容器5和气液分离器6处于使用状态时，液平衡管7的一端位于第一回油孔6022的下方或者液平衡管7的一端和第一回油孔6022位于同一高度；液平衡管7的一端位于第二回油孔6032的下方或者液平衡管7的一端和第二回油孔6032位于同一高度。液平衡管7的另一端位于第一回油孔6022的下方或者液平衡管7的另一端和第一回油孔6022位于同一高度；液平衡管7的另一端位于第二回油孔6032的下方或者液平衡管7的另一端和第二回油孔6032位于同一高度液平衡管。
例如，如图1和图2所示，容纳腔5011的底壁面和分离腔6011的底壁面位于同一高度，液平衡管7的第一端701(e)与容纳腔5011的底壁面之间的距离为L1，第一回油孔6022(a)与分离腔5011的底壁面之间的距离为L2，液平衡管7的第二端702(f)与分离腔6011的底壁面之间的距离为L3，第二回油孔6032(c)与分离腔6011的底壁面之间的距离为L4，其中，L2≥L1、L4≥L1、L2≥L3且L4≥L3。
由此，液平衡管7的高度不高于第一回油孔6022和第二回油孔6032，从而有效保证容纳腔5011内的冷冻油可以通过液平衡管7进入分离腔6011，以便分离腔6011内的冷冻油能够分别通过第一回油孔6022和第二回油孔6032返回第一压缩机1和第二压缩机2内，有利于进一步提升压缩机组件的可靠性。
在本公开的实施例中，如图1至图3所示，存储容器5包括第一进气管502和第二进气管503，第一进气管502的一部分伸入到容纳腔5011内，第二进气管503的一部分 伸入到容纳腔5011内。第一进气管502的一部分和第二进气管503的一部分中的每一者设有制冷剂进口，第一出油口302和第二出油口402中的每一者与第一进气管502的制冷剂进口连通。
例如，第一进气管502的制冷剂进口为第一制冷剂进口5021，第二进气管503的制冷剂进口为第二制冷剂进口5031。第一进气管502和第二进气管503中的每一者包括第一部分和第二部分，第一进气管502的第一部分和第二进气管503的第一部分均伸入到容纳腔5011内，第一进气管502的第二部分和第二进气管503的第二部分位于容纳腔5011外，第一制冷剂进口5021设在第一进气管502的第一部分上，第二制冷剂进口5031设在第二进气管503的第一部分上。
也就是说，第一制冷剂进口5021既作为冷冻油的进口，又作为制冷剂的进口；第二制冷剂进口5031仅作为制冷剂的进口使用。
第一进气管502和第一出油口302通过第五管15连通，第二进气管503和第二出油口402通过第六管16连通。
在另一些实施例中，存储容器5包括第一进气管502和第二进气管503，第一进气管502的一部分和第二进气管503的一部分中的每一者伸入到容纳腔5011内。第一进气管502的一部分和第二进气管503的一部分中的每一者均设有制冷剂进口，第一出油口302与第一进气管502的制冷剂进口连通，第二出油口402与第二进气管503的制冷剂进口连通。
此时，第一进气管502的制冷剂进口为第一制冷剂进口5021，第二进气管503的制冷剂进口为第二制冷剂进口5031。第一制冷剂进口5021既作为冷冻油的进口，又作为制冷剂的进口；第二制冷剂进口5031既作为冷冻油的进口，又作为制冷剂的进口。
在本公开的实施例中，液平衡管7的一端伸入壳体501内部，以便液平衡管7的一端与容纳腔5011连通。液平衡管7的另一端伸入筒体601内部，以便液平衡管7的另一端与分离腔6011连通。
例如，如图1至图3所示，液平衡管7的第一端701伸入壳体501内部，液平衡管7的第二端702伸入筒体601内部。
在一些实施例中，容纳腔5011的底壁面和分离腔6011底壁面位于同一高度，液平衡管7的一端和液平衡管7的另一端位于同一高度。换言之，液平衡管7水平设置。第一回油孔6022和第二回油孔6032位于同一高度。
例如，如图1至图3所示，容纳腔5011的底壁面和分离腔6011的底壁面位于同一高度，上述L1＝L3，L2＝L4。
由此，在进行压缩机组件的组装时，只需要将容纳腔5011的底壁面和分离腔6011的底壁面处于同一安装高度即可，方便压缩机组件的组装。
在本公开的实施例中，液平衡管7和气平衡管8中的每一者为直管。
例如，如图1和图2所示，液平衡管7为直管，液平衡管7与存储容器5的连接端口为e，液平衡管7与气液分离器6的连接端口为f，e和f等高，液平衡管7的第一端 701、液平衡管7的第二端702中的每一者与连接端口e(连接端口f)等高。
在本公开的实施例中，液平衡管7和气平衡管8中的至少一者为弯管。
例如，如图3所示，液平衡管7包括第一管段703、第二管段704和第三管段705，第二管段704水平设置，第一管段703和第三管段705中的每一者倾斜设置，第二管段704的一端与第一管段703的下端相连，第二管段704的另一端与第三管段705的下端相连。
第二管段704的两端分别与存储容器5和气液分离器6相连，且第二管段704与存储容器5的连接端口为e2，第二管段704与气液分离器6的连接端口为f2。第一管段703伸入容纳腔5011内，第三管段705伸入分离腔6011内，且第一管段703的远离第二管段704的一端e1为第一端701，第三管段705的远离第二管段704的一端f1为第二端702。此时，连接端口为e2与e1位于不同高度，连接端口为f2与f1位于不同高度。
在一些实施例中，第一出气管602的一部分具有与分离腔6011连通的第三回油孔6023，第二出气管603的一部分具有与分离腔连通的第四回油孔6033。其中，第三回油孔6023位于第一回油孔6022的上方或者第三回油孔6023和第一回油孔6022位于同一高度。第四回油孔6033位于第二回油孔6032的上方或者第四回油孔6033和第二回油孔6032位于同一高度。
例如，如图1至图3所示，第三回油孔6023(b)与分离腔6011的底壁面之间的距离为L5，第四回油孔6033(d)与分离腔6011的底壁面之间的距离为L6，其中，L5≥L2且L6≥L4。
由此，当第一压缩机1通过第一回油孔6022回油不及时或者第一回油孔6022因故无法回油时，第一压缩机1能够通过第三回油孔6023实现回油，第二压缩机2通过第二回油孔6032回油不及时或者第二回油孔6032因故无法回油时，第二压缩机2能够通过第四回油孔6033实现回油。从而可以进一步避免压缩机因回油不及时、或无法回油导致的压缩机因缺少润滑而磨损，进而进一步提升了压缩机组件的可靠性。
在一些实施例中，第三回油孔6023和第四回油孔6033位于同一高度。
例如，当容纳腔5011的底壁面和分离腔6011的底壁面位于同一高度时，上述L5＝L6。
由此，可以进一步减少甚至避免因第一压缩机1和第二压缩机2的容量不同，引起的制冷剂分配偏差大的问题，有利于进一步提升压缩机组件的可靠性。
在一些实施例中，气平衡管8的一端位于第三回油孔6023的上方或者气平衡管8的一端和第三回油孔6023位于同一高度，气平衡管8的一端位于第四回油孔6033的上方或者气平衡管8的一端和第四回油孔6033位于同一高度。气平衡管8的另一端位于第三回油孔6023的上方或者气平衡管8的另一端和第三回油孔6023位于同一高度，气平衡管8的另一端位于第四回油孔6033的上方或者气平衡管8的另一端和第四回油孔6033位于同一高度。
例如，如图1和图3所示，容纳腔5011的底壁面和分离腔6011的底壁面位于同一 高度时，气平衡管8的一端(g)与容纳腔5011的底壁面之间的距离为L7，L7≥L5，气平衡管8的另一端(h)与分离腔6011的底壁面之间的距离为L8，L8≥L6。
由此，本公开实施例的压缩机组件可以更好的利用气平衡管8实现容纳腔5011和分离腔6011内的气平衡，进而利用液平衡管7实现容纳腔5011和分离腔6011内的液平衡，有利于进一步提升压缩机组件的可靠性。
在一些实施例中，第三回油孔6023在上下方向上位于气平衡管8的一端与液平衡管7的一端之间，第三回油孔6023在上下方向上位于气平衡管8的另一端与液平衡管7的另一端之间。第四回油孔6033在上下方向上位于气平衡管8的一端与液平衡管7的一端之间，第四回油孔6033在上下方向上位于气平衡管8的另一端与液平衡管7的另一端之间。
例如，容纳腔5011的底壁面和分离腔6011的底壁面位于同一高度时，上述L7＞L5＞L1且L8＞L6＞L2。
由此，有利于进一步提升压缩机组件的可靠性。
在一些实施例中，容纳腔5011的底壁面和分离腔6011的底壁面位于同一高度。液平衡管7的一端和液平衡管7的另一端位于同一高度。换言之，液平衡管7水平设置。气平衡管8的一端和气平衡管8的另一端位于同一高度。换言之，气平衡管8水平设置。
由此，在进行压缩机组件的组装时，只需要将容纳腔5011的底壁面和分离腔6011的底壁面处于同一安装高度即可，方便压缩机组件的组装。
在一些实施例中，第一出气管602的一部分和第二出气管603的一部分中的每一者包括U形部分。U形部分包括第一段、第二段和中间段，第一段和第二段中的每一者沿上下方向延伸，中间段的一端与第一段的下端相连，中间段的另一端与第二段的下端相连。
第一回油孔6022设在第一出气管602的中间段上，第三回油孔6023设在第一出气管602的第一段上，第二回油孔6032设在第二出气管603的中间段上，第四回油孔6033设在第二出气管603的第一段上。
