Abstract

一种复合式热交换机，其利用空气在含工作介质 对的热交换机上进行自反馈闭路循环，改变各膜式蒸 发面上的焓值，经反复运作而得到较高(或较低)的温 度。

Description

本发明涉及一种复合式热交换机。
不设压缩机的开放式制冷机（俗称冷风机），是使空气运行通过含有工作介质（清水）的纱布，使部分工作介质在常温下汽化，利用其汽化时要吸收热量的特性来使运行其上的空气被吸热，达到制冷目的。
上述方法制冷有若干缺点，除效能低外，吹出气体含丰富水气，不利于生活环境中的人、物。
本发明的目的在于提供一种复合式热交换机。
本发明的目的是这样实现的，即提供一种复合式热交换机，利用空气在含工作介质时的开放式热交换机上进行自反馈循环，改变各膜式蒸发面上的焓（热含量），而得到低（或高）温。
本发明的热交换机利用工作介质对在特设结构中的循环运行而使其在不同的位置实现互补进行的吸收或蒸发。上述互补吸收或蒸发通过在一导热板两侧分别设置膜面，其中一侧为膜式蒸发面、另一侧为膜式吸收面实现的，两侧分别有空气运行，促使两面工作介质各起作用，进行有效的吸、放热的热交换。上述热交换运行其上的空气增（降）温。在吸收面及蒸发面上设导热分割片及绝热区隔片，使每一作用面两侧成微分分割状态（理想状态），形成最有效的热交换。上述整体结构中工作介质对形成一自反馈循环，并为良性循环。
本发明复合式热交换机的优点在于其向室内送入不含富湿气的新鲜空气，制冷降温效果好。
以下结合附图，描述本发明的实施例，其中：
图1为本发明热交换机立体原理示意图;
图2为图1中热交换机纵向放大剖视图;
图3为图1中热交换机横向放大剖视图;
图4为本发明热交换机制冷机示意图。
如图1、2、3所示，为本发明热交换机工作原理说明图，热交换机包括导热片1、膜式蒸发面2、膜式吸收面3、导热分割片4、绝热区隔片5等。在上述膜式蒸发面2及膜式吸收面3上流动的是“工作介质对”。
工作介质对采用的工作介质是两种沸点不同的物质组成的二元混合物，其中沸点低的物质为制冷剂，沸点高的物质为吸收剂;例如氨水溶液，其中氨为制冷剂，水为吸收剂。
如图1～3所示，在导热片1两侧贴有耐腐蚀、吸湿性良好、表面蓬松的疏松孔布（如聚丙烯晴纤维），其一侧为流动工作介质g1（后述）的膜式蒸发面2，另一侧为流动工作介质g2（后述）的膜式吸收面3，膜式蒸发面2上及膜式吸收面3上都有空气运行，为使上述分别运行的空气与膜式蒸发面2及膜式吸收面3有效地进行热交换，在这些空气流通道上设置具有导热或隔热功能的导热分割片4及绝热区隔片5，上述导热分割片4及绝热区隔片5以一定间距纵向（dxn）及横向（dyn）分隔，使导热片1形成被细隔区分的“微分”状态，使每一导热片1（及其两侧）被切割成许多细小的区块，每一单一区块都能进行有效的传热。
如图4所示的本发明一种制冷机的实施例，图中g1是吸水后含水较多的稀LiCl或LiBr溶液，g2是被解吸后浓度较高的LiCl或LiBr溶液;室外空气为a，室内空气为b。该图说明将室外引入空气a予以降温，而将室内空气增温排出的情形。
微型泵将g2连续地输向g2渗液管6，使g2连续、缓慢地均布于膜式吸收面3，g2逐渐吸收水分成为g1，并流入g1积液盘7，被另一微型泵连续地送至g1渗液管8均布于膜式蒸发面2上，g1在膜式蒸发面2上解吸、微分吸热解吸而成为g2，并向下流至g2积液盘9中，然后继续上述循环。
图中热交换机含有解吸换热器10、蒸发换热器11及吸收换热器12。
在前后两组蒸发面中管道中设隔离板13、14，使室内b呈纵向运行。
自然空气a1被送风机分为二股进入g1解吸，一股a′在膜式蒸发面2解吸面上微分吸热、吸水使g1失水成为g2，由a′2形态排向大气;另一股a2沿虚线方向在解吸换热器10的导热分割片4内微分放热后进入蒸发换热器11的导热分割片4沿a3方向继续微分放热，a3进入吸收换热器12的膜式解吸面后进一步微分放热、析湿成为a4输出。a4是冷谷（即室内，形成送入室内冷空气的状态）。
a4从低温热源吸取热量、湿量后（即室内空气）成为b1被吸入膜式蒸发面2进行逐步增湿、增湿的微分吸热由
Figure 941069575_IMG2
后排放向大气。
上述复合系统总可使a3趋近于a4的温度，而a3总可在吸收换热器12内继续放热而获得更低温、低温度的a4
上述由a1→a2→a3→a4的空气逐渐降温、析湿，而
Figure 941069575_IMG3
则吸取热量、湿量;两者在本发明的热导热片1两侧分别呈垂直方向进行，而直接进行互补换热。
复合式热交换机可以反向制热，将解吸换热器10的两股气体a2和a′2都排向大气，形成连续将g1解吸成g2，以提供吸收换热器12的加热能量。吸收换热器12的制热工作介质（空气）进行自反馈闭路循环，吸热、吸湿后的b′3改道输入膜式解吸面进行微分析湿放热，所释放的热量被膜式蒸发面b′3吸收，再进入膜式蒸发面，使得b′3吸收，再进入膜式蒸发面，使得b′3和a4的焓值由于反复加热、加湿而升高。
综上所述，由于室内、室外空气的被导向运行，运行中的空气分别对膜式蒸发面或膜式吸收面上的工作介质对进行吸湿、吸热或析湿、放热，同时，上述的吸湿、吸热、析湿、放热皆对同一导热片工作，互补进行。再有，焓值变化的工作介质对又可互相供给对方使用，形成自反馈形态。
上述复合式热交换机可设置成若干组，且可对其导热片两侧蒸发面功吸收面变换地使用。
