Description

一种应用于马鞍式窗机的管路应力测试方法及马鞍式窗机 技术领域
本发明涉及空调器技术领域，尤其涉及一种应用于马鞍式窗机的管路应力测试方法及马鞍式窗机。
 背景技术
应力测试是空调器出厂前必须做的一项测试，管路在外力或者非均匀压力/温度场中会产生应变，也就是管路的形变率，这是个无量纲数，应变量大会导致管路断裂，因此需要将应变量控制在一定的范围内。应力测试就是测试应变量是否超标。
马鞍式窗机主要包括室内部分、室外部分以及鞍桥部分，通过鞍桥部分将室内部分与室外部分分离，有效的降低了室内噪音。安装时窗机骑跨在窗口上，鞍桥部分可以伸缩，以调节室内部分与室外部分之间的距离，以适应不同厚度的墙体。马鞍式窗机的n型结构导致里面的管路是经过特殊设计的，以允许管路能够适应鞍桥部分的伸缩。
现有的管路应力测试方法只适用于普通的窗机，普通窗机只是需要一个实验室台位，稳定好工况就可以测试。而n型结构的马鞍式窗机和安装方法都和普通窗机差别很大，安装方法对于最大应变量影响很大，需要根据用户的实际使用场景来尽可能的模拟最大应变量，因此马鞍式窗机不能用常规的应力测试方法来进行测试，否则测试结果会有出入。

本实施例公开一种马鞍式窗机，参照图1，其包括位于室内侧的室内机100、位于室外侧的室外机200、以及连接室内机100和室外机200的鞍桥结构300。
该马鞍式窗机为n型结构，室内机100和室外机200分别设于鞍桥结构300的两端、且位于鞍桥结构300的同侧，室内机100和室外机200朝向鞍桥结构300的下方延伸。
将马鞍式窗机安装至窗口上时，鞍桥结构300直接坐落在窗口上，室内机100位于室内侧，室外机200位于室外侧。
由于室内机100和室外机200均位于窗口的下方，所以该马鞍式空调器解决了现有一体式窗机安装后遮挡阳光的问题。
通过鞍桥结构300将室内机100与室外机200分离，有助于避免室外机200的噪音传到室内侧，提高用户使用舒适度。
室内机100主要包括机壳、室内换热器、接水盘、贯流风扇、风道等部件。
室外机200主要包括机壳、室外换热器、轴流风扇、压缩机等部件。
本申请一些实施例中，鞍桥结构300可以伸缩，通过鞍桥结构300长度的调节，以调节室内机100与室外机200之间的距离，以适应不同厚度的墙体。
鞍桥结构300可以设置多个伸缩档位，便于调节和使用。
马鞍式窗机的换热管路主要包括回气管组、过冷管组、排气管以及泡水管等。过冷管组的一端与蒸发器（对应室内换热器）的进液端连接，另一端与泡水管连接；回气管组的一端与蒸发器的出气端连接，另一端与压缩机的吸气口连接；排气管的一端与冷凝器（对应室外换热器）的进气端连接，另一端与压缩机的排气口连接；泡水管的一端与过冷管组连接，另一端与冷凝器的出液端连接。
冷媒管路穿经鞍桥结构300，具体为回气管组和过冷管组穿经鞍桥结构300。由于鞍桥结构300可以伸缩，回气管组和过冷管组都需要具备一定的伸缩量，以适应鞍桥结构300的伸缩调节。那么窗机在出厂前做冷媒管路的应力测试时，则需要充分考虑由于鞍桥结构300伸缩所带来的冷媒管路的应力变化，以保证窗机在出厂后的实际过程中，无论用户将窗机拉伸至何位置，冷媒管路都能够满足应力要求，保证窗机管路的安全性，避免冷媒泄露。
冷媒管路应力测试方法主要包括以下步骤：
1、通过CAE仿真手段确定冷媒管路的应力测试点，在应力测试点处布置传感器；
2、确定窗机在实验台600上的安装位置，实验台600模拟窗口和墙体的结构，在实验台600上设置墙体610，实验时将窗机骑跨在墙体610上，确定室内机100与墙体610之间的距离、以及室外机200与墙体610之间的距离；
3、窗机准备完成，开始应力测试；
4、测试完成后输出报告，从报告中可以看出哪个管路的具体哪个部位存在风险点。
其中，步骤2和3是本实施例的重点改进技术点，以下详述。
在步骤2中，根据马鞍式窗机的抽拉档位确定窗机的两个测试状态，分别为完全拉伸测试状态和未拉伸测试状态，因为这两种状态可以覆盖窗机的所有档位状态，即可以覆盖最不利于应力测试的状态。
利用根据公式ε=a×（W2/L1+W1/L2）来确定窗机的安装位置，具体的，设定室内机100的重量为W1，室外机200的重量为W2，室内机100与墙体610之间的距离为L1，室外机200与墙体610之间的距离为L2，冷媒管路的应变量为ε。
鞍桥结构300在未拉伸状态下L1+L2=Y min，鞍桥结构300在完全拉伸状态下L1+L2=Y max，根据不同型号的窗机，Y min和Y max为已知数据，比如本实施例中鞍桥结构300在未拉伸时L1+L2=240mm，鞍桥结构300在完全拉伸时L1+L2=400mm。
冷媒管路的应变量ε的理论上限值记为ε max1，针对具体型号的冷媒管路，其为已知数据，比如本实施例中，ε max1=280μs，则可以得到应变系数a=ε max1×（W1/L1+W2/L2）。
将应变系数a重新带入公式ε=a×（W2/L1+W1/L2）中，
鞍桥结构300在未拉伸状态下得到推导公式ε max2=ε max1（W1/L1+W2/( Y min-L1）) ×（W1/L1+W2/( Y min-L1)）；
鞍桥结构300在完全拉伸状态下得到推导公式ε max2=ε max1（W1/L1+W2/( Y max-L1）) ×（W1/L1+W2/( Y max-L1)）；
其中，ε max2为冷媒管路应变量ε的实际上限值，ε max2＜ε max1，窗机在实际使用时，冷媒管路的实际应变量需要小于ε max2，若实际应变量超过ε max2，则冷媒管路就存在断裂、泄露冷媒的风险。
根据上面两个推导公式，即可得到冷媒管路应变量ε的实际上限值ε max2、以及应变量取ε max2时所对应的L1，那么鞍桥结构300未拉伸状态下，L2= Y min-L1；鞍桥结构300完全拉伸状态下，L2= Y max-L1，这样也即确定了窗机分别在未拉伸状态和完全拉伸状态下的具体安装位置。
在步骤3中，需要分别测试鞍桥结构300在未拉伸状态和完全拉伸状态下的冷媒管路应变量，在每一种窗机安装状态下，都需要分别测试窗机在启动、运行以及停机三种工作状态下的冷媒管路应变量，冷媒管路在所有状态下的应变量ε都不能超过实际上限值ε max2，在超过，则冷媒管路测试不合格，存在安全风险。
鞍桥结构300在未拉伸状态下，按照应变量ε取ε max2时所对应的L1和L2将窗机安装至墙体610上，其中L2= Y min-L1，分别测试窗机在启动、运行以及停机三种工作状态下的冷媒管路应变量。
鞍桥结构300在完全拉伸状态下，按照应变量ε取ε max2时所对应的L1和L2将窗机安装至墙体610上，其中L2= Y max-L1，分别测试窗机在启动、运行以及停机三种工作状态下的冷媒管路应变量。
本申请中的马鞍式窗机的应力测试方法，能够根据窗机实际使用场景来尽可能的模拟冷媒管路的最大应变量，能够测试出窗机在最不利状态下的应变量，保证管路应力测试的准确性和可靠性，提高窗机在实际使用过程中管路的安全性，有效避免窗机在不同安装状态及使用状态下出现冷媒管路应力过大而导致管路断裂、泄露冷媒的情况。
本申请一些实施例中，窗机在启动、运行以及停机三种状态下进行应力测试时，在每个状态下都分别测试窗机在额定电压Ue、电压（Ue-u1）、以及电压（Ue+u2）下的冷媒管路应变量，进一步提高管路测试的准确性和可靠性。
u1和u2可以取值额定电压Ue的10%，也即分别测试窗机在额定电压Ue、额定电压的90%、以及额定电压的110%下的冷媒管路应变量。
本申请一些实施例中，窗机在启动工作状态下进行冷媒管路应力测试时，测试压缩机达到额定频率后的时间段t1内的冷媒管路应变量，t1比如可以取值40s。
本申请一些实施例中，窗机在运行工作状态下进行冷媒管路应力测试时，测试压缩机稳定运行后的时间段t2内的冷媒管路应变量，t2比如可以取值180s。
本申请一些实施例中，窗机在停机工作状态下进行冷媒管路应力测试时，测试窗机关机前时间段t3以及关机后时间段t4内的冷媒管路应变量比如，t3可以取值20s，t4可以取值60s。
本申请一些实施例中，在窗机安装至实验台600上后、进行管路测试之前，需要通过水平尺来测量窗机的水平状态，保证窗机各个方向上的倾斜角不能大于1度，通过在鞍桥下面垫高和微调室外机后背板上的手拧螺栓来调整水平状态，有助于提高管路测试的准确性。
本申请一些实施例中，冷媒管路包括回气管组500，参照图14，回气管组500包括依次连通的第一回气管路段510、第二回气管路段520以及第三回气管路段530。第一回气管路段510与室内换热器连接，第三回气管路段30与设于室外机中的压缩机220连接，第二回气管路段520为U型结构、且位于鞍桥结构300的内腔中。
回气管组500的三段式结构便于加工，提高工艺水平。当鞍桥结构300拉伸时，U型的第二回气管路段520起到了一定的管路拉伸的缓冲量，满足了鞍桥结构300的伸缩功能。
第一回气管路段510在靠近其端部的位置处设有弯折部分（在图14中标记为c1处）以与室内换热器连接，第三回气管路段530在靠近其端部的位置处设有弯折部分（在图14中标记为c2处）以与压缩机220连接，弯折部分c1和c2处为应力测试点。
本申请一些实施例中，第二回气管路段520的U型结构为半圆形结构，在整机运行时，管路的震动其实就是力的传送，而第二回气管路段520的半圆形结构受力时，在圆弧结构上的力在传动中会互相抵消，这样就起到了减震的作用，同时管路所设计的弧形形式，相对方形或类似方形的管路形式，在同等空间下，半圆形的结构形式所用的管路量比较少，在一定程度上减少了管路成本。
本申请一些实施例中，参照图13，鞍桥结构300的内腔中设有电器盒400，第二回气管路段520穿设于电器盒400与鞍桥结构300的内腔侧壁之间的空隙、并且水平地围绕在电器盒400的一侧，充分利用鞍桥结构300的内部空间，实现走管。
电器盒400位于第二回气管路段520的U型结构所围空间内，当鞍桥结构300拉伸时，电器盒400左右两侧能够有足够的余量来保证抽拉过程中管路不与电器盒400接触。
本申请一些实施例中，第二回气管路段520上套设有弹簧540，防止第二回气管路段520在拉伸过程中压扁或瘪了。
第二回气管路段520的外周包覆有隔热套（未图示），隔热套包覆在弹簧540的外周，避免第二回气管路段520上产生冷凝水流入到电器盒400中。
本申请一些实施例中，第三回气管路段530包括依次连接的第三回气管路一段531、第三回气管路U型段532以及第三回气管路二段533，第三回气管路U型段532的敞口朝上，第三回气管路一段531与第二回气管路段520连接，第三回气管路二段533与压缩机220的吸气口连接。
第三回气管路U型段532起到了辅助拉伸变形的作用，能够承担一小部分的拉伸力，起到缓冲作用，避免直接连接压缩机220后给压缩机一个横向力导致压缩机受力影响性能和震动。
第三回气管路U型段532的底部弯折部分处（在图14中标记为c3）为应力测试点。
本申请一些实施例中，参照图4和图5，鞍桥结构300包括内鞍桥壳310和外鞍桥壳320，外鞍桥壳320套设于内鞍桥壳310的外侧，内鞍桥壳310与外鞍桥壳320可以相对运动，以实现鞍桥结构300的伸缩，冷媒管路穿经所述内鞍桥壳310。
内鞍桥壳310的一端与室内机100和室外机200中的一者连接，外鞍桥壳320的一端与室内机100和室外机200中的另一者连接，以通过鞍桥结构300将室内机100与室外机200连接在一起。
图7至图9所示为内鞍桥壳310的结构示意图，图10至图12所示为外鞍桥壳320的结构示意图，图2至图5所示结构中，内鞍桥壳310与室内机100连接，外鞍桥壳320与室外机200连接。
本申请一些实施例中，内鞍桥壳310与外鞍桥壳320之间设有滑动部，以使内鞍桥壳310与外鞍桥壳320之间的滑动运动更为可靠、顺畅。滑动部可以为滑轨结构，也可以为设于二者之间的滑道、滑块结构等。
本申请一些实施例中，内鞍桥壳310和外鞍桥壳320分别具有向下延伸的竖向部，竖向部构成室内机100和室外机200的后背板。
鞍桥结构300通过两个竖向部分别与室内机100和室外机200固定连接，有助于提高室内机100、室外机200及鞍桥结构300三者之间的结构稳固性。
鞍桥结构300能够承载一部分室内机100和室外机200的重量，通过鞍桥结构300将重量转移到窗口上，有助于提高马鞍式空调器整机安装后的安全性，减小坠机风险。
本申请一些实施例中，参照图4和图5，鞍桥结构300还包括鞍桥罩壳330，内鞍桥壳310与外鞍桥壳320相互远离运动时，鞍桥罩壳330将露出的内鞍桥壳310遮挡。
本申请一些实施例中，参照图2，室外机200的后背板上设有调节螺栓210，在将窗机放置到窗口上、并将鞍桥结构300调节至相应的长度档位后，拧动调节螺栓210，使调节螺栓210抵靠于室外侧墙体，进一步提高窗机的安装稳固性。
对于内鞍桥壳310的具体结构，本申请一些实施例中，参照图7至图10，内鞍桥壳310包括内鞍桥L型底板311和内鞍桥盖板312，内鞍桥盖板312设于内鞍桥L型底板的横向部3111的顶部，围成第一贯通腔313。

对于外鞍桥壳320的具体结构，本申请一些实施例中，参照图10至图12，外鞍桥壳320包括外鞍桥L型底板321和外鞍桥盖板322，外鞍桥盖板322设于外鞍桥L型底板的横向部3221的顶部，围成第二贯通腔323。
外鞍桥L型底板的竖向部3212构成室外机200的后背板，外鞍桥L型底板的竖向部3212与室外机200的底板固定连接。
外鞍桥L型底板的横向部3221与竖向部3222的转接位置处设有外鞍桥加强板324，进一步提高外鞍桥L型底板321的结构强度。
对于鞍桥罩壳330的具体结构，本申请一些实施例中，参照图6，鞍桥罩壳330包括鞍桥罩壳顶板331和鞍桥罩壳侧板332，鞍桥罩壳顶板331将鞍桥结构300的顶部遮挡，鞍桥罩壳侧板332将鞍桥结构300的侧面遮挡。
鞍桥罩壳侧板332为L型结构，鞍桥罩壳侧板的横向部3321将鞍桥结构300的侧面遮挡，鞍桥罩壳侧板的竖向部3322与室内机100的侧板固定连接，构成室内机100侧面的一部分，同时实现鞍桥罩壳330在室内机100上的固定安装。
本申请一些实施例中，参照图3和图5，鞍桥罩壳侧板的横向部3321上设有向其内侧凸出的凸起部333，凸起部333与外鞍桥壳320通过连接件（比如螺钉）固定连接，实现内鞍桥壳310与外鞍桥壳320相对运动至所需位置后的定位。
鞍桥结构300拉伸到位后，在鞍桥罩壳330的左右侧壁打螺钉，将鞍桥罩壳330的左右侧壁与外鞍桥壳320的左右侧壁对应固定连接，鞍桥罩壳330与外鞍桥壳320固定连接，由于内鞍桥壳310和鞍桥罩壳330均与室内机100固定连接，而外鞍桥壳320与室外机200固定连接，从而实现鞍桥结构300在固定位置处的止位固定。
凸起部333的设置，使得在鞍桥罩壳330的外侧面上形成凹陷，螺钉嵌入凹陷结构内，避免螺钉的外端面外凸于鞍桥罩壳330而划伤用户。
本申请一些实施例中，参照图13，内鞍桥壳310的内腔中设有电器盒400，电器盒400贴靠于内鞍桥壳310的一侧壁设置，电器盒400与内鞍桥壳310的另一侧壁之间具有供换热管路（指回气管组和过冷管组）走管和排水管路走管的间隙。
电器盒400的设置位置充分利用了鞍桥结构300的内部空间，使整机结构更为紧凑。
电器盒400贴靠于贯通腔的一侧设置，电器盒400与贯通腔的另一侧之间形成用于空调器的换热管路和排水管路走管的空隙，排水管路和换热管路从电器盒400的一侧延伸走线，使鞍桥结构300内部结构更为规整、紧凑。
本实施例中的鞍桥结构300不仅起到了连接室内机100与室外机00的作用，还起到了安装电器盒400、走管、走线的作用，多功能集成，结构更为紧凑。
本申请一些实施例中，电器盒400的一侧具有倾斜壁410，倾斜壁410在竖直面内倾斜，用于在鞍桥结构300伸缩时避让换热管路和排水管路，避免鞍桥结构300伸缩时对换热管路和排水管路产生干涉。
本申请一些实施例中，电器盒400固定设于内鞍桥L型底板的横向部3111上，电器盒400顶部敞口，便于内部电器件的安装，利用内鞍桥盖板312对电器盒400的顶部敞口进行封堵。
本申请一些实施例中，电器盒400与围成鞍桥结构300贯通腔的内壁接触的位置处设有缓冲密封部315，缓冲密封部315一方面起到减振作用，另一方面可避免凝结在鞍桥结构300内壁上的冷凝水滴落在电器盒400的内部，提高电器盒400的防水性能。
作为一种具体实施例，参照图9，内鞍桥盖板312的内侧设有缓冲密封部315，密封缓冲部315与电器盒400的顶部贴合密封抵靠，并将电器盒400的顶部敞口全部覆盖。电器盒400的顶部敞口结构便于电器盒400内部电器件的安装，鞍桥结构300的内壁（具体为内鞍桥盖板312）充当了电器盒400的顶盖作用，简化结构，降低成本。
在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。以上仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
