Description

压缩机、空调系统和汽车 技术领域
本发明涉及空调技术领域,特别涉及一种压缩机、空调系统和汽车。
背景技术
电动汽车作为一种新能源汽车,具有节能环保的优势,车载空调系统作为其中的耗能部件,既要能实现快速制冷制热又要保持低功耗,因此,电动汽车的空调系统对压缩机的能效要求和制冷制热能力要求更高。特别是在严寒的冬天,外部环境温度低于-10度,电池输出效率变低,此时车载空调需要在如此恶劣的环境温度实现快速制热且保持高能效,这对车载压缩机的能效和应用环境有了更高的要求。
要实现超低温快速制热的功能,常规压缩机仍然很难满足要求,就需应用增焓技术。例如,涡旋压缩机具有节能、噪音低、可靠性高的特点,故被广泛用作最新一代车载压缩机。然而常规涡旋压缩机很难满足超低温快速制热的要求,目前业内需要应用增焓技术来解决涡旋压缩机超低温快速制热的问题。相比于常规空调系统,带增焓系统的空调系统更为复杂,如带增焓系统和涡旋压缩机的空调系统,需要额外增设中间冷却结构即闪发装置,管路和空间设置要求更多,其结构可以参照图1所示。而空调系统中过多的管路设置对电动汽车的续航能力和系统本身的可靠性都是一种考验。

为了满足电动车用空调系统超低温快速制热的需求,本发明提出一种更适用于电动车载的增焓空调系统,其车载电动压缩机集中间冷却闪发装置一体化设计,简化了车载增焓空调系统,提高系统的可靠性。
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的 所有其他实施例,都属于本发明保护的范围。
本发明图2至图3所示的实施例提供的空调系统,包括压缩机11、冷凝器12和蒸发器13;压缩机11包括对制冷剂进行压缩的压缩腔体17,其核心改进点在于,
压缩机11还包括能进行液态制冷剂闪发的闪发腔体18,以及连通闪发腔体18的闪发腔体气体出口和压缩腔体17的增焓补气接口之间的连通通道19;
闪发腔体18的闪发腔体入口连通于冷凝器12的出口,闪发腔体18的闪发腔体液体出口连通于蒸发器13的入口,其结构可以参照图2和图3所示。
工作原理:从蒸发器13中蒸发出的低压制冷剂气体源源不断地被吸入压缩机11内进行压缩。低压的制冷剂气体Ps被压缩成高温高压制冷剂气体Pd从压缩机11排出进入冷凝器12内。高温高压制冷剂气体在冷凝器12内等压冷却后再进入压缩机11的闪发腔体18。液态制冷剂在闪发腔体18内进行闪发。闪发出的制冷剂气体通过连接通路19直接进入压缩腔体17内,实现对压缩腔17进行冷却增焓的作用。尚未闪发的制冷剂液体进入蒸发器13内进行蒸发换热,蒸发换热成的低压制冷剂气体继续被吸入压缩机11的压缩腔体17内进行压缩。从而实现制冷剂在空调系统中的循环,源源不断的利用机械能作功转换成热能。
从上述的技术方案可以看出,本发明实施例提供的空调系统,闪发器装置与压缩机11一体化设计,无需在系统中额外再增加闪发器结构,减少了空间,精简空调系统;同时,闪发后气体能够快速进入压缩腔17,减少中间管路压力损失和传热温升,提升补气增焓效率,进而进一步提升压缩机低温制热性能;另外,设置在压缩机11机身上的闪发结构同压缩机11一并固定连接在汽车上,比传统自带闪发器结构的空调系统具有更好的耐振动性能,提升整个车载增焓系统的可靠性。本设计特别适用于车载增焓空调系统。
作为优选,闪发腔体18和压缩腔体17相邻,两个腔体通过一个共用侧壁分隔。这样一来,就进一步简化了空调系统的结构,同时拉近了两个腔体之间的距离,使连接通路19尽可能的短,减少中间管路压力损失和传热温升,提升补气增焓效率进而进一步提升压缩机低温制热性能。
在本方案提供的具体实施例中,连通通道19设置于上述共用侧壁。
为了进一步优化上述的技术方案,共用侧壁上开设有通孔作为连通通道19,连通通道19直接连通闪发腔体气体出口和和压缩腔体17的增焓补气接口,实现闪发腔体 18闪发出来的中间冷却气体能直接进入压缩腔体17,增焓冷却效果更好。
作为优选,压缩机11的机身外壁面构成闪发腔体18的一部分。在充分利用机身外壁面精简结构的同时,还便于闪发腔体18各管路的连接。如图3所示,压缩腔体17居中设置,闪发腔体18位于其一侧,驱动部分位于另一侧,如此组成压缩机11的主体,结构紧凑。
为了进一步优化上述的技术方案,压缩机11采用铝合金制机身。充分利用压缩机铝合金制机身可机加工性的特点,铝合金开启式结构相比于传统的钢板圆筒全封闭结构具有更多的可加工性。铝合金机身结构的压缩机使得将外部的闪发器结构一体化设计在压缩机整机上十分方便,能充分发挥出一体化结构的优势配置。
在本方案提供的具体实施例中,压缩机11为电动压缩机,包括驱动泵体进行压缩的驱动电机16,采用压缩腔体17居中,闪发腔体18和驱动电机16分别位于其两侧的布置形式,结构紧凑。
本发明提供的电动车用增焓空调系统主要包括压缩机11、冷凝器12、蒸发器13、系统管路14等四大部件。压缩机11集吸气、压缩、排气以及中间闪发一体化设计,使得整个增焓系统结构紧凑,可靠性高。本发明的一体式的压缩机11包括:驱动泵体进行压缩的驱动电机16、对制冷剂进行压缩的压缩腔体17、能进行液态制冷剂闪发的闪发腔体18以及连通闪发腔体和压缩腔体的连通通道19。
如图1所示的现有技术的增焓空调系统,与本发明不同的是需要在压缩机01和冷凝器02中间额外设置闪发器05,经闪发器05闪发出的制冷剂气体需要通过闪发器气体出口a和压缩机增焓补气接口b之间的补气增焓管路后再进入压缩机01的压缩腔内实现增焓补气。
本发明实施例的空调系统相比现有技术的空调系统,具有如下特点:
1、轻量化空调系统
车载空调系统有别于家用或者商用空调系统,其内部安装空间有限且要求系统尽量轻便,特别是电动汽车对此要求尤为严格,电池既需要为驱动电机提供电力,又需要为车载空调系统提供电力。因此,电动汽车需要更轻的车身配置以便提高续航能力。为了减轻重量,电动车用压缩机一般都采用铝合金开启式结构,铝合金开启式结构相比于传统的钢板圆筒全封闭结构具有更多的可加工性。铝合金机身结构的压缩机,使得将外部的闪发器结构一体化设计在压缩机整机上十分方便,能充分发挥出一体化结 构的优势配置。如图2所示的车载空调系统,与现有系统相比,由于无专门的闪发器,可以使得系统配置的更为紧凑,虽然在压缩机上再设计闪发腔体会使得压缩机机身增大,但是相比额外增加闪发器,一体化压缩机机身在空间占用方面更有优势,因为在设计闪发器腔体时可充分利用压缩机机身外围空间,使得一体化的结构更为紧凑。传统的闪发器装置都是在系统中设置专门的闪发罐,再通过管路连接压缩机、冷凝器和蒸发器,而本发明的一体化的闪发腔体设置在压缩机的机身上,即压缩机机身外壁面作为构成闪发腔体的一部分。
2、补气增焓通路短,补气效果更稳定,能提供更舒适温度的室内温度
如图1所示的连接闪发器气体出口a和压缩机增焓补气接口b之间的补气增焓管路,在增焓空调系统设置时,受空间结构的影响,补气增焓管路长度首先很难作为首要考虑因素,其次,管路外部环境温度受汽车运行车速影响。因此,从闪发器闪发出来的制冷剂气体在经过补气增焓管路后,因为压力损失和传热导致气体状态属性变化,相比于从闪发腔体闪发后直接进入压缩腔体相比,其增焓效果较差,压缩机实际运行工况不稳定从而导致室内温度波动,影响室内的舒适度,同时,由于压缩机工况波动也会影响压缩机的可靠性。
3、一体化结构设计使得增焓系统耐振动性能好
相比于家用或商用空调系统,车载空调系统振动剧烈,对车载空调系统的耐振动性能要求更高。而本发明采用的闪发器结构和压缩机机身一体化的结构设计,如图3所示,闪发腔体18作为压缩机的一部分结构同压缩机整体固定在车体上,同压缩机具有相同的振动特性。而如图1所示的现有技术方案,闪发器05和压缩机分别固定在车体上,受自身结构的影响,压缩机和闪发器的振动特性各异,导致连接闪发器和压缩机之间的补气增焓管路振动剧烈,影响整个系统的可靠性。而本发明实施实例的连接闪发腔体和压缩腔体之间的连通通道直接设置在压缩机内部,不存在该处的管路振动。从而使得整个增焓系统耐振动性能更好。
如图3所示的本发明实施实例的一体化压缩机结构示意图,在铝合金机身的压缩机上设置闪发腔体18,闪发腔体18直接连通压缩腔体17,制冷剂一经闪发即进入压缩腔体18冷却压缩腔,增焓冷却效果更好。
本发明实施例还提供了一种汽车,包括空调系统,其核心改进点在于,空调系统为上述的空调系统。特别是新能源汽车,尤其是电动汽车。
该设计更适用于电动车载增焓空调系统,其车载电动压缩机集中间冷却闪发装置一体化设计,简化了车载增焓空调系统,提高系统的可靠性,满足了电动车用空调系统超低温快速制热的需求。
综上所述,本发明实施例提供了一种空调系统,包括电动压缩机、蒸发器、冷凝器、闪发器以及连接整个系统的各种管路,其中闪发器结构与电动压缩机一体化设计,实际的主要构件仅包括压缩机、蒸发器、冷凝器以及连接整个系统的各种管路。构成本系统的电动压缩机不仅包括驱动电机、压缩腔,还包括具有闪发功能的闪发腔。一体化的压缩机结构使整个增焓系统更为简单,减省额外再设置闪发器的空间,使得更适用于空间有限的车载空调系统上。
本发明实施例还提供了一种应用上述空调系统的汽车,尤其是电动汽车。
下面结合图4~图17对本发明提供的另外一些实施例的技术方案进行详细的阐述。
参见图4,本发明实施例提供一种涡旋压缩机,包括本体,所述本体设有流入口100、压缩腔体200、排出口(图未示出)和闪发腔体300。流入口100、排出口和闪发腔体300均与压缩腔体200连通。其中,压缩腔体200被构造成用于压缩经由流入口100进入的第一流体;闪发腔体300用于闪发形成第二流体并将其输送至压缩腔体200内被压缩。
流入口100作为吸气口,排出口作为排气口,通过流入口100、排出口和压缩腔体200实现涡旋压缩机常规的吸气、压缩、排气功能。
涡旋压缩机设有两个腔体:压缩腔体200和闪发腔体300。压缩腔体200位于空调系统主循环回路上,闪发腔体300则用于对压缩腔体200进行补气增焓。一种可能的方式是,进入闪发腔体300的液体来自于空调系统的冷凝器22。另一种可能的方式是单独为闪发腔体300设置供液部件。本实施例中,以前种方式为例详加介绍。
闪发腔体300与压缩腔体200的连通位置较佳为:闪发腔体300与涡旋压缩机吸气完成后形成的移动腔室连通。即闪发腔体300向压缩腔体200输送的第二流体不参与涡旋压缩机的吸气过程,不作为被吸气体的一部分(被吸气体即第一流体),而是直接进入压缩腔体200内被压缩。
闪发腔体300的大小与压缩机的排量有关。
上述技术方案,作为闪发器的闪发腔体300与涡旋压缩机一体化设计,减少了在 空调系统中额外增加闪发器占用的空间,精简了空调系统;同时闪发后气体直接进入压缩腔体200,减少中间管路压力损失和传热温升,提升补气增焓效率,进而进一步提升压缩机低温制热性能。同时,设置在压缩机机身上的闪发腔体同压缩机一并固定连接在汽车上,比传统自带闪发器的空调系统其具有更好的耐振动性能,提升整个车载增焓系统的可靠性。
闪发腔体300可以为铸造成型或者机加工成型,闪发腔体300内部更加方便地设置各种气液分离结构,有效地减少增焓气体带液现象,提高压缩机可靠性。设置在机身上的闪发腔体既可以用于增焓闪发,又可以配置在常规增焓系统上用于增焓气体气液分离用,扩展了压缩机的应用范围。
参见图4,涡旋压缩机的本体包括静涡旋盘3、动涡旋盘4和壳体。静涡旋盘3具有第一端板31和从第一端板31向外伸出的第一螺旋涡卷32。动涡旋盘4具有第二端板41和从第二端板41向外伸出的第二螺旋涡卷42。第一螺旋涡卷32和第二螺旋涡卷42交错在一起,当动涡旋盘4相对于静涡旋盘3转动时,在第一螺旋涡卷32和第二螺旋涡卷42之间限定出共同作为压缩腔体200的多个移动腔体。静涡旋盘3和动涡旋盘4设于壳体内部,闪发腔体300设于壳体,和/或,闪发腔体300设于静涡旋盘3。
本实施例中,以闪发腔体300设于壳体为例,具体来说,参见图1,壳体包括可拆卸连接的第一盖1和第二盖2。第一盖1位于静涡旋盘3未设置第一螺旋涡卷32的一侧,闪发腔体300设于第一盖1。
为了保证进入到压缩腔体200的第二流体不夹杂液体或者尽量少的混带液体,可选地,参见图7和图8,闪发腔体300内部设有与第二流体流动方向倾斜的气液分离结构102,气液分离结构102用于形成折流通道,以分离第二流体中夹杂的液体。
夹杂有液体的第二流体流经气液分离结构102后,液体附着在气液分离结构102上,被分离出来。分离得到的纯净的第二流体被输送至涡旋压缩机的压缩腔体200,用于补气增焓。
承上述,闪发腔体300可完全形成在第一盖1内部,除了流体进出口外,没有别的敞口。
或者,在第一盖1上形成开口结构,由密封盖板13和固定螺栓16封闭该开口,即图4至图9、图11至图13、以及图15示意的情形。如图8、图9所示,为本实施例闪发腔体300的一种实施例。闪发腔体300形成于第一盖1的轴向上,上端为开口式 结构,通过密封盖板13和螺栓零件进行密封。第三开口101(对应于闪发腔体气体出口)及其延伸通道105均位于第一盖1内部。如图8、图9所示的这种开启式闪发腔体300结构最容易实现,可直接通过壳体毛坯铸造成型,且能获得较大的闪发腔体300体积而外围材料少,壳体总重量和体积不至于增大较多。
或者,闪发腔体300的部分腔体形成在第一盖1上,部分腔体形成在密封盖板13上。第一盖1和密封盖板13共同形成整个闪发腔体300,即图10示意的情形。如图10所示为本发明实施实例提供的另一种闪发腔体300,其开启式开口开设在第一盖1顶端,第一开口103设置在密封盖板13上。
下面介绍气液分离结构102的结构以及设置位置。
图7和图8中,气液分离结构102包括挡板,两个挡板相对呈八字分布。闪发腔体300内第二流体的流动方向参见图17所示。其中箭头示意的是闪发后夹杂有液体的第二流体的流动方向。
参见图17,气液分离结构102与第二流体流动方向呈钝角或直角。气液分离结构102包括挡板,即挡板的平面延展方向与第二流体流动方向呈钝角或直角,即角α为钝角或直角。
参见图8,气液分离结构102可以全部设于第一盖1;或者,参见图14,气液分离结构102可以全部设置于密封盖板13。或者,如图16所示,也可以在第一盖1和密封盖板上相互错开地设置挡板。
参见图9和图16,壳体包括可拆卸连接的第一盖1、第二盖2和密封盖板13。第一盖1位于静涡旋盘3未设置所述第一螺旋涡卷32的一侧,密封盖板13设于第一盖1远离第二盖2的一侧。闪发腔体300部分设于第一盖1,闪发腔体300的另一部分设于密封盖板13。在第一盖1和密封盖板上相互错开的设置挡板,会在闪发腔内形成如图15所示的折流空间,其气液分离效果会更好。效果好是挡板设置数量较多产生的,这种分开设置即能增加折流腔数目,又相比仅设置在一结构件上折流阻力小。且如果挡板仅设置在一结构件上,挡板紧密也会导致加工成型难度大。
下面介绍闪发腔体300与压缩腔体200之间的连通关系。
参见图5,压缩腔体200设有与闪发腔体300连通的通孔303(对应于增焓补气接口)。曲轴9驱动动涡旋盘4相对于静涡旋盘3转动,在转动过程中,每转动一圈,压缩腔体200与闪发腔体300周期连通一次,或称为间歇连通。
参见图7,闪发腔体300的用于通入待闪发流体的第一开口103(对应于闪发腔体入口)设于闪发腔体300的顶端,闪发腔体300的用于输出未被闪发液体的第二开口104(对应于闪发腔体液体出口)设于闪发腔体300的底端,闪发腔体300用于输出闪发得到的第二流体的第三开口101设于闪发腔体300的顶端。闪发得到的气体即第二流体。闪发腔体300的第三开口101与压缩腔体200连通。
待闪发流体为液体,将第一开口103设于闪发腔体300的顶端,在待闪发流体从闪发腔体300顶端流到闪发腔体300底部的过程中,除了闪发外,还能因为气体、液体重力不同实现一定的气液分离作用。闪发剩余的液体会聚集在闪发腔体300底部,而后经由位于闪发腔体300底部的第二开口104输出。闪发得到的第二流体是气体,气体会聚集于闪发腔体300的上部,而后经由位于闪发腔体300顶部的第三开口101输出至压缩腔体200内。
具体地,参见图4和图5,进一步地,静涡旋盘3的第一端板31内设有连通通道33,通过连通通道33将闪发腔体300与压缩腔体200的通孔303连通。
参见图11,一种可选的方式是,连通通道33包括连通的轴向通道301和径向通道302,轴向通道301远离径向通道302的一端与闪发腔体300连通,径向通道302远离轴向通道301的一端与压缩腔体200连通。
参见图12,另一种可选的方式是,第三开口101的延伸通道105直接对应压缩腔内指定位置处的通孔303,闪发腔体300内闪发气体直接通过第三开口101进入压缩腔体200内。如图13为对应本实施实例的静涡旋盘3的结构,与图11所示的静涡旋盘3的结构相比,该实施方式的静涡旋盘3上省去了径向通道302和密封螺纹塞15,具有结构简单,静涡旋盘3加工方便的优点。当然,由于第三开口101对应的是静涡旋盘3上对应压缩腔体200内指定位置处的通孔303,受通孔303孔位的影响,第三开口101的闪发腔体300内的位置也会发生变化。
下面结合附图介绍一个实例。
本发明实施例提供的涡旋压缩机,其吸气-压缩-排气过程与常规的涡旋压缩机一致。动涡旋盘4由上支架5支撑,在驱动电机6的带动下,曲轴9带动动涡旋盘4转动,在动涡旋盘4和静涡旋盘3之间形成不断周期变化的压缩腔体200,制冷剂气体在压缩腔体200内完成吸气、压缩以及排气的过程。驱动控制器7控制驱动电机6的转速。副轴承8、主轴承10、尾部轴承11共同支撑曲轴9。第一盖1和第二盖2之间通 过固定装配螺栓12螺纹连接。图5中,虚线表示闪发腔体内闪发的制冷剂气体(第二流体)的流动状态。
本实施例中,以涡旋压缩机设置在空调系统中为例。如图5所示,本发明实施实例的涡旋压缩机第一盖1具有额外的闪发腔结构,即闪发腔体300。该闪发腔体300具有三个开口,三个开口分别为连接冷凝器22出口的第一开口103,连接蒸发器23入口的第二开口104,连接压缩腔体200的增焓补气接口的第三开口101,且闪发腔体300内倾斜布置有挡板。
从冷凝器22出来的液体制冷剂在该闪发腔体300内实现闪发,尚未闪发的液体制冷剂通过第二开口104继续流向蒸发器23,闪发冷却后的制冷剂气体通过第三开口101进入压缩腔体200,液体制冷剂在该闪发腔体300内完成闪发-冷却-增焓的过程。
静涡旋盘3具有与闪发腔体300的第三开口101密封连接的连通通道33,该连通通道33形成于静涡旋盘3的第一端板31内,该连通通道33一端连接第三开口101,另一端连接压缩腔体200的指定位置处的通孔303,实现在压缩机曲轴转角的一定指定范围内将闪发腔体300内的制冷剂向压缩腔体200引入。
参见图11所示,上述闪发腔体300的第三开口101与静涡旋盘3的连通位置可以设置在静涡旋盘3靠外围的位置,静涡旋盘3的第一端板31设置轴向通道301和径向通道302以连通上述闪发腔体300和压缩腔体200。这种结构适用于各个实施例。
参见图13所示,第三开口101与静涡旋盘3的连接位置也可以直接设置在压缩腔体200指定位置处,静涡旋盘3的第一端板31内仅开设轴向通道301。这种结构适用于各个实施例。
参见图6,冷凝器22出来的高温高压的制冷剂液体18通过第一开口103进入压缩机21的闪发腔体300,如图4所示,高温高压的制冷剂液体进入闪发腔体300后由于容积空间的突然变大,压力降低。该闪发腔体和单独的闪发结构一样,制冷剂液体由于进入容积突然变大的空间,一部分液体迅速闪发成低温的气体,尚未闪发的高温制冷剂液体因闪发吸热冷却为较低温度的液体。图5中实线箭头表示制冷剂液体在第一盖1内的闪发腔体300内的流动路径。闪发的低温制冷剂气体流向如图5中虚线箭头表示,闪发的低温制冷剂气体通过第三开口101流出并进入静涡旋盘3内的连通通道33。
图5中,第三开口101的延伸通道105对应静涡旋盘3上的较外围位置,在静涡 旋盘3较外围对应位置处开设有轴向通道301,在轴向通道301上设置与第三开口101的延伸通道105密封的O型密封圈14,以实现两者之间的密封作用。其中在静涡旋盘3的第一端板31内还设置径向通道302以连通轴向通道301和压缩腔体200的通孔303。径向通道302通过密封螺纹塞15密封。于是,从第三开口101流出的制冷剂气体能通过上述密封连通的通路进入压缩腔体200内,实现对压缩腔体200的增焓补气。
本发明实施实例的闪发、冷却、增焓的过程仅通过上述的闪发腔体300和连通通道33完成,省去了中间的管路和结构设置。如图6所示,从闪发腔体300内冷却的制冷剂液体19从第二开口104流出后直接进入蒸发器23,这一系统设置方式有助于简化增焓系统结构,更适应于对安装空间和安装重量要求严格的车载空调系统上。
图6中,虚线是示意系统管路,当压缩机不补气增焓时,系统上冷凝器22出来的制冷剂液体通过该管路流向后续结构。
如图7所示,流入压缩腔体200的第三开口101设置于闪发腔体300的最顶端,流入蒸发器23的第二开口104设置在闪发腔体300的低端,在闪发腔体300内设置与第二流体流动方向成倾斜角度的挡板,将制冷剂流动路径分为折流路径,有助于制冷剂的气液分离,保证进入压缩腔体200内的制冷剂带液少。
如图17所示,在闪发腔体300内,实际的流体状态为尚未闪发的制冷剂液体以及成沸腾状态的气液混合态。图17中,闪发出的气液混合态制冷剂211在流向第三开口101的过程中,通过设置的挡板(挡板的结构可以为实体平板或表面带孔的板)实现气液分离。挡板与制冷剂流动方向成一定倾斜角度,图17中虚线箭头所示为气液混合态制冷剂211的流动方向,当气液混合态制冷剂211碰触到挡板后,液态制冷剂222因为表面张力作用会大部分黏附在挡板壁面上,气液混合态制冷剂`211进行气液分离。图17中,实线箭头为分离出来的液态制冷剂222在挡板上的流动方向。由上可知,通过在闪发腔体300内设置挡板能有效地对闪发腔体300内闪发后的气液混合态制冷剂211进行气液分离,防止向压缩腔体200带液补气,增加压缩机的可靠性。
如图11所示,静涡旋盘3上分别开设轴向通道301和径向通道302。压缩腔体200指定位置处的通孔303以及径向通道302尾端设置内螺纹304。该通孔303的尺寸可大于、等于或小于螺旋涡卷的涡旋齿的齿壁厚度,根据向压缩腔体200补气要求而定。如果需要向压缩腔体200的内外移动腔体交替补气,通孔尺寸要小于涡旋齿的齿壁厚度但尽量越大越好。如希望同时向压缩腔体200的内外移动腔体补气,则通孔303的 尺寸可以大于涡旋齿的齿壁厚度,但也不能太大,需满足压缩腔体200的密封要求。通孔303的孔位尽可能设置在靠近压缩腔体200吸气闭合后的位置,根据压缩腔体200的内外移动腔体的吸气闭合情况设定。
本发明另一实施例提供一种空调系统,包括本发明任一技术方案所提供的涡旋压缩机21。
可以单独设置流体供给部件向闪发腔体300供给流体。即,空调系统还包括流体供给部件,流体供给部件与涡旋压缩机21的闪发腔体300连通,闪发腔体300被构造成能将流体供给部件供给的流体闪发形成第二流体。
或者,将空调系统中的液体供给给闪发腔体300,具体地,闪发腔体300的第一开口103与冷凝器22出口连通,冷凝器接入管17将冷凝器22与第一开口103连通。闪发腔体300的第二开口104与蒸发器23入口连通,闪发腔体300的第三开口101与涡旋压缩机的压缩腔体200连通。
本发明再一实施例提供一种新能源汽车,包括本发明任一技术方案所提供的空调系统。
本说明书中各个实施例采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
