Abstract

本发明提供了一种涡旋压缩机，其设置有注射管，该注射管延伸穿过顶部壳体并进入固定涡旋件。该注射管相对于固定涡旋件被固定，并且可以被压配合或者以其他方式固定。该布置简化了进入涡旋压缩机的注射端口。

Description

用于将流体注射到涡旋压缩机的注射管
技术领域
本发明涉及一种涡旋压缩机，其具有将流体注射到压缩端口并通过顶部壳体的注射管。
背景技术
涡旋压缩机广泛使用在制冷压缩应用中。在涡旋压缩机中，第一涡旋件具有基部和从基部延伸的大体螺旋的涡旋齿。第二涡旋件具有基部和从其基部延伸的大体螺旋的涡旋齿。两个涡旋件的涡旋齿相互配合以便限定压缩腔室。第二涡旋件相对于第一涡旋件做绕行运动，并且在第二涡旋件相对于第一涡旋件做绕行运动时，压缩腔室的尺寸减小并且分路的制冷剂被压缩。
有许多用于制冷循环的改进，例如那些包括涡旋压缩机的制冷循环。一个改进是使用节能循环。在节能循环中，由压缩机压缩的制冷剂输送到下游冷凝器。在冷凝器的下游，制冷剂的一部分被分路并膨胀。被分路的膨胀制冷剂以与主制冷剂流成热交换关系流入节能热交换器内。这辅助冷却了主制冷剂流，并且在下游的蒸发器提供了附加能力。节能热交换器下游的被分路的膨胀制冷剂通过节能器的注射端口流回至涡旋压缩机内。通常，这发生在中间压缩位置。
在现有技术中，节能器的流体或其他流体通过压缩机的壳体的侧壁被注射，并且进入第一涡旋件的基部内。需要复杂的通路、盖板等。想要的是简化对涡旋压缩机的节能注射。
在一个公知的涡旋压缩机中，节能器的注射端口延伸穿过涡旋压缩机的顶部。然而，在该提出的涡旋压缩机中，第一涡旋件是可以沿轴向运动类型的涡旋件。因此，第一涡旋件不固定到节能器的注射管，而是沿注射管滑动。
发明内容
在本发明的公开实施例中，涡旋压缩机设置有非绕行涡旋件，该非绕行涡旋件固定在中心壳体内。顶部壳体封装涡旋压缩机。固定涡旋件在吸入腔室和排出腔室之间提供分离点。流体注射端口由延伸穿过顶部壳体、并进入固定涡旋件的基部中端口的管提供。在一个实施例中可以利用两个分离的管，或者单个管可以延伸穿过顶部壳体，然后分支成两个管。
本发明的这些和其他特征可以从下面的描述和附图中更好地理解，下面的描述是简要的描述。
附图说明
图1示出了本发明的第一实施例；
图2示出了本发明的第二实施例；
图3示出了本发明的第三实施例。
具体实施方式
图1示出了涡旋压缩机20。固定涡旋件22被固定在壳体部件26和28之间。绕行涡旋件24相对于固定涡旋件22绕行运动。马达21驱动绕行涡旋件24。
固定涡旋件22相对于壳体部件26和28密封，使得吸压腔室45形成在一侧上，并且排压腔室31形成在相对侧上。压缩腔室被限定在固定涡旋件22和绕行涡旋件24之间，并且分路的制冷剂如公知的被压缩和输送到排压腔室。该压缩的制冷剂输送到排出管30和下游的冷凝器32。从冷凝器32流出的制冷剂的一部分在34处被分路并在35处膨胀。该制冷剂流入节能热交换器36，在节能热交换器中制冷剂冷却主制冷剂流38。虽然两种流动被示出为沿相同方向流过节能热交换器36，但是，实际上可以使用逆流方向。然而，为了表示方便，两种流动被示出为沿相同方向流动。从主流动管线38流出的制冷剂然后经过膨胀装置40、蒸发器42，并通过吸入管44返回至吸压腔室45。
被分路的膨胀制冷剂经过歧管46返回至压缩机，歧管与分离管48连通。分离管48延伸穿过顶部壳体26，进入注射端口52，注射端口与压缩腔室相连。焊缝100可以焊接开口50，分离管48通过开口延伸穿过顶部壳体26。分离管48可以压配合到固定涡旋件22的基部。
该布置与现有技术相比简化了节能器的流体注射。
图2示出了实施例60，该实施例与图1的实施例大体相同，除了只有单一管62延伸穿过顶部壳体26。焊缝100如第一实施例中的设置一样。分支的流动通道64压配合到开口66内。
图3示出了实施例100，其中顶部壳体102具有管106，管106以与上述实施例相同的方式被固定，但是延伸穿过顶部壳体102的侧壁。再次的，管106将制冷剂输送到端口66。在实施例100中，管106连接到液体制冷剂源，而不是连接到节能器的回路。
虽然前两个实施例公开为返回节能器的流体，但是通过本申请中公开的将管固定到顶部壳体也可以完成各种流体制冷剂、甚至是油的任何数量的其他注射。
本发明的每个实施例与现有技术相比提供了简单的装配和结构。
虽然本发明的实施例已经公开，但是本领域的普通技术人员将会认识到某些改进落入本发明的保护范围内。为此，随附的权利要求书将确定本发明的真实范围和内容。
