Description
技术领域
本发明涉及一种空气调节和除湿设备和方法,更具体地说,涉及一种使用干燥剂轮技术来控制湿度同时提供增加的空气流动流量的空气调节方法和设备。
背景技术
众所周知,传统的空气调节设计不能很好地适应于处理建筑物空间的湿度负荷和温度负荷两者。通常,建筑物空间中的湿度负荷的主要来源来自于需要向该空间供应外部补充空气,因为该空气通常具有比建筑物中所需的水分含量更高的水分含量。在传统的空气调节系统中,空气调节单元的冷却能力因此被设定大小以适应峰值温度设计条件下的潜热(湿度)和显热(温度)条件。当存在足够的冷却需求时,实现了适当的除湿能力。然而,封闭空间上的湿度负荷不直接随温度负荷变化。即,在早晨和夜晚期间,室外的绝对湿度几乎与在更高温度的中午时段期间相同。因此,在那些时候,通常不需要在空间中进行冷却,因此不进行除湿。因此,先前存在的空气调节系统对于这些条件来说设计地并不好。这些条件有时会导致建筑物内的不舒服的情况,并且可能导致在建筑物及其管道系统内形成霉菌或产生其它微生物。另一方面,存在空气的水分含量需要更少的除湿但同时仍需要相同或更多空气流动流量的时间段或地理区域。
已经提出了许多现有技术装置,使用干燥剂冷却系统来解决这些问题。在这些装置中,首先使用干燥剂轮等对来自大气的供应空气进行除湿,然后使用热交换器对该空气进行冷却。来自该空气的热量通常被传递至再生气流,并且用于提供干燥剂再生能力需求的一部分。补充空气直接原样输送到空间,或者替代地通过直接蒸发装置或通过更传统的制冷剂型空气调节设备来冷却。干燥剂轮用第二气流再生,该第二气流来自被空气调节的封闭区或来自外部空气。这种类型的干燥剂冷却系统可以被设计成提供非常封闭且独立的湿度和温度控制,但是它们的安装通常比传统系统更昂贵。
Meckler的美国专利No.3,401,530、Carlton的美国专利No.5,551,245和Maeda的美国专利No.5,761,923公开了其它混合型装置,其中空气首先通过制冷系统冷却并用干燥剂干燥。然而,在所有这些公开中,需要高的再生温度来充分地再生干燥剂。为了达到这些高温,需要双制冷剂回路来将再生温度升高或增加到140°F以上。在Meckler的专利的情况下,使用来自发动机的废热而不是冷凝器热量。
在美国专利No.6,557,365、No.6,711,907和No.7,047,751中已经提出了更好的解决方案,它们仅利用环境空气向封闭区供应空气,并且仅利用环境空气再生干燥剂。这种系统可以利用潮湿条件的外部空气,例如在美国的南部和东南部以及在亚洲国家是典型的,并且使其处于空间中立条件。这些系统具有优于用于从外部空气在室内空气舒适区域条件下产生空气的替代技术的显著优点。最显著的优点是低能量消耗。也就是说,用干燥剂辅助处理空气所需的能量小于先前公开的冷却技术中所使用的能量。
然而,这种系统基于所使用的干燥剂轮的尺寸而具有空气流动流量限制。因此,在一些需要额外空气流动流量的情况下,可能需要多个单元来满足流量需求。在空气干燥的气候条件下,取决于周围气候,这种单元可以提供比所需更温暖和更干燥的空气。在这种情况下,本发明允许在期望的温度和湿度下供应更大量的调节空气。
发明内容
本发明的目的是处理外部供应空气并将其调节到更大的空气流动流量中所需的需求,而不需要额外的或更大的干燥剂轮,并且因此是一种有效且经济的方式。
本发明的又一个目的是提供一种制造和操作相对便宜的、具有较高空气流动流量的基于干燥剂的除湿和空气调节系统。
本发明的另一个目的是提供一种空气调节系统,其使得操作者能够改变干燥剂处理过的供应空气与不需要进一步干燥的额外体积的冷却外部空气的比例。
根据本发明的一个方面,一种空气调节和除湿系统和方法利用位于壳体中或内的多个空气室,该壳体具有由中间壁分开的第一空气室和第二空气室。第一空气室被用于供应和处理环境气流,然后将处理过的空气供应到封闭区或其它待冷却或处理的区域。该系统还包括液体蒸汽制冷回路,该液体蒸汽制冷回路包含位于第一空气室中的蒸发器和位于第二空气室中的冷凝器盘管,该蒸发器用于对进入第一空气室的环境空气进行冷却和除湿。
供气风扇与第一空气室相关联,以将环境空气抽吸入空气室并将处理过的空气从空气室供应给封闭区、区域或空间。冷凝器风扇与第二空气室相关联以将另一环境气流抽吸到第二空气室中,该另一环境气流然后穿过冷凝器并被加热。
干燥剂除湿系统包括在该系统中,该干燥剂除湿系统利用可旋转地安装的干燥剂轮,该干燥剂轮安装成横向于中间壁并穿过中间壁延伸,使得该轮的一区段存在于第一处理空气室中,而另一区段存在于第二空气室中,该轮位于冷凝器的下游以接收在冷凝器中加热的空气作为再生空气以在操作期间在干燥剂轮旋转时使干燥剂轮再生,并且之后将再生空气排出到大气。
第三环境空气室也被设置作为环境空气旁路,环境空气通过该旁路根据所需的流量需要被选择性地供应给封闭区或空间,而不需要在第一空气室中通过干燥剂轮进行处理。第三空气室包含用于在将冷却的第三环境气流供应到封闭区之前冷却由风扇等抽吸入第三空气室的环境空气的装置。冷却装置可以是来自水冷却器系统的冷却器盘管或来自DX制冷系统的蒸发器盘管,所述DX制冷系统独立于与第一空气室和第二空气室一起使用的DX系统。
在本发明的另一方面中,通过利用DX制冷系统的蒸发器冷却盘管冷却第一环境供应气流,然后使这样冷却和除湿的第一气流通过旋转的干燥剂轮的处理区段以进一步降低第一环境气流中的水分含量,来将调节的空气供应到封闭区或空间。此后,将该处理过的第一环境气流供应到所述封闭区。
干燥剂轮由供应到第二空气室的第二环境气流再生,该第二环境气流在通过第二空气室中的干燥剂轮区段之前首先通过第二空气室中的DX冷凝器盘管(在该处其温度升高)以使干燥剂轮再生。在通过干燥剂轮之后,第二环境气流被排放到大气中。
此外,优选地通过风扇将第三环境气流选择性地供应到第三空气室,所述风扇优选地独立于与所述第一空气室和第二空气室相关联的那些风扇。该第三气流在被供应到封闭区之前在不被干燥剂轮处理的情况下由DX系统选择性地冷却,所述DX系统独立于在第一空气室和第二空气室中使用的冷却系统。替代地,代替在第三气流中具有风扇,可以在干燥剂轮的下游在第三环境气流和第一气流之间设置挡板,其中风扇也在干燥剂轮的下游位于第一气流中,使得第一气流中的一个或多个风扇将全部体积的空气从第一空气室和第三空气室抽吸通过系统。
这样,通过改变来自第三空气室的冷的环境空气的供应体积和/或温度,用户可以增加供应到封闭区的环境空气的体积,以在当环境温度和湿度条件使得操作者所需要的在更大的空气体积下对所有环境空气进行除湿并非必须时能够更好且更有效地控制输送到封闭区的空气的温度和湿度。
附图说明
在结合附图阅读的本发明的说明性实施例的以下详细描述中,本发明的上述和其它目的、特征和优点将变得显而易见,其中:
图1是现有技术的空气调节和湿度控制单元的示意性俯视图;
图2是图1所示的现有技术单元的示意性侧视图;
图3是根据本发明的空气调节和湿度控制单元的示意性侧视图;
图3A是根据本发明的空气调节和湿度控制单元的另一个实施例的示意性侧视图,其包括可选的预处理装置;
图4是图3的实施例的视图的俯视图,其中为了清楚起见,旁通空气室被移除;
图4A是图4所示的空气室18的示意性侧视图,包括旁通空气室;以及
图4B是图4所示的空气室16的示意性侧视图,包括旁通空气室。
具体实施方式
现在详细参照附图,首先参照图1和2,示出了现有技术空气调节单元10,其类型通常为在美国专利No.6,557,365、6,711,907和7,047,751中公开的类型。该单元10包括具有分隔壁14的空气室12,该分隔壁通常位于空气室中央并将空气室分成单独的空气室,即第一空气室16和第二空气室18。该单元旨在基本上仅使用外部环境空气,以便在适当或期望的温度和湿度条件下将调节的除湿空气供应到封闭区或空间20。
图1的现有技术的空气调节单元还包括相关联的直接式液体蒸汽压缩膨胀制冷系统(DX)24,DX系统24包括蒸发器或冷却盘管26和冷凝器盘管28,以及未示出的常规压缩机和膨胀阀,上述部件通过以点划线示出的液体蒸汽管道30连接。
如图1和2所示,蒸发器盘管26位于第一空气室16中,靠近空气室12中的环境空气入口31。冷凝器盘管28位于空气室18中,靠近空气室12中的另一环境空气入口32。风扇34和36设置在空气室16和18中或连接到空气室16和18,以将环境空气抽吸入相应的空气室中。
空气室12还包含传统的可旋转的干燥剂轮38,其可旋转地安装在空气室12中,横向于壁14并部分地延伸穿过壁,使得当单元运行时,在轮的旋转期间,轮的一区段(大约一半)暴露于空气室16、18中的环境气流。这些区段在第一空气室16中被标示为40(也被称为用于处理空气的处理区段),在第二空气室18中被标示为42(也被称为用于再生气流的再生区段)。
在操作中,现有技术的单元连续地将经调节的外部空气供应到封闭区。来自封闭区的废气通过风扇等(未示出)以任何方便的方式排出,如本领域已知的。第一环境或处理气流A被风扇34抽吸入空气室16,在那里它被蒸发器盘管26冷却和除湿。然后气流A在区段40中被干燥剂轮38进一步除湿。适当的控制被用于DX系统24并改变轮38的旋转速度,以便通过空气室12中的开口44离开空气室16的空气具有用于空间20的期望温度和湿度条件。
在该系统中,环境或外部空气也用于再生干燥剂轮。由风扇36抽吸入的外部空气通过冷凝器盘管28以增加第二环境气流B的温度,然后该加热的气流通过干燥剂轮38的再生区段42以从轮去除湿气。然后,第二或再生气流被排放到大气中。该现有技术系统还可以具有将来自封闭区的空气的一些或全部提供到环境气流A以在空气室16中进行处理的装置。
如上所述的现有技术的空气调节单元已经非常有效并且成功地使用。然而,在某些气候条件下或对于某些设施,使用者需要比一个单元所能处理的气流量更大的气流量来调节所涉及的空间,同时需要更少的空气除湿来实现待供应到封闭区或空间的气流量的期望湿度条件。为了满足这种需要,通常需要使用两个或更多个这样的单元,这增加了用户的费用或者产生了比所涉及的空间所需的除湿更多的除湿。
然而,已经发现,某些区域中的气候条件可能使得能够利用单个单元和除湿轮来实现对通向封闭区的空气供应的充分除湿。
这些问题已经通过本发明解决,本发明利用单独的第三环境气流,根据用户的要求和环境条件,所述第三环境气流没有或有一些附加的冷却和除湿,不需要在干燥剂轮上附加的除湿。
图3和4示出了根据本发明的空气调节和除湿单元50的附加的实施例。在这些图中,图1和2中使用的附图标记用于表示该实施例中的相应部件。
如现有技术中那样,图3所示的单元50具有由中间壁14分开的第一空气室16和第二空气室18(图3中未示出)。构成处理或供应气流OA的环境空气在风扇34的影响下在开口31处进入空气室12。如图3所示,如果需要或期望,气流可以首先通过常规空气过滤器52,然后通过水冷却器54进行初步冷却。替代地,在开口31的下游和冷却盘管26之前,还可以有单独的DX系统(未示出)的冷凝盘管,当条件允许时,该冷凝盘管将向周围空气放热。在另一个替代实施例中,还可以有单独的DX冷却盘管以用于初步冷却,其中当条件允许时,系统中的冷凝盘管向周围空气放热。
来自冷却器54的空气在DX系统蒸发器盘管26中被处理(在那里空气被干燥和冷却),然后通过干燥剂轮38的处理空气区段40(在那里空气被进一步干燥)。所述空气从处理空气区段被供应到封闭区或空间20。
第二环境气流通过风扇36(图4)抽吸入壁14的与空气室16相对的一侧上的空气室18中。所述第二环境气流首先通过DX系统的冷凝器盘管28以被加热,并且如前所述,然后通过干燥剂轮38的再生区段42以再生轮;然后将第二环境气流排出到大气中。
第三空气室55(图3)被设置成将一定体积的冷却的环境空气供应到封闭区,而不通过干燥剂轮。该空气室以任何方便的方式设置,并且图示为管道,该管道安装在空气室16和18的顶部58上方的空气室12上或形成为空气室的一部分,然而,应当理解,该管道可以任何方便的方式与系统相关联。
如图3所示,第三空气室55可以通过空气室12的顶壁58中的通道56与第一空气室16连通。通道56被任何方便的或已知结构的挡板60打开或关闭,使得当挡板打开或部分打开时,被抽吸入空气室16的一些环境空气也被第三空气室风扇64抽吸入空气室55。挡板60被任何已知的控制系统控制以打开或关闭挡板或将其保持在在部分打开的位置以控制进入第三空气室的空气量。
空气室55中的第三气流可以根据需要由DX制冷系统的蒸发器盘管59或由单独的水冷冷却器选择性地冷却,该DX制冷系统独立于第一空气室和第二空气室中使用的DX系统24。
冷却的第三气流绕过壳体12中的干燥剂轮,并且在挡板68的控制下通过另一通道或开口66返回到干燥剂轮下游的空气室16中的第一或处理气流。挡板68由本领域技术人员所理解的控制系统打开和关闭。
在另一个替代实施例中,可以去掉风扇64,并且单独使用风扇34以将外部空气抽吸入空气室16,然后使得一部分空气在通过蒸发器26之前通过通道56进入空气室55,在两个实施例中,第一气流和第三气流混合并一起供应到封闭区。在条件允许的情况下,在第一空气室中干燥足够的空气,以降低所需供应空气量的一部分的湿度和温度,同时简单地冷却环境空气的一部分(并且当使用蒸发器盘管59时部分地干燥),使得当两股气流混合时,最终具有封闭区中所需的期望的总体温度和湿度条件。在该实施例中,代替使用挡板60来控制气流,风扇64可以被设置为调节风扇,其可以改变从通道56通过空气室55的外部气流,或者如下所述通过端壁69中的环境空气入口的外部气流。
应当理解,代替上述通道56和挡板60,第三空气室可以被构造成使得环境空气入口被设置在其端壁69中,该环境空气入口可以由类似于上述挡板60的挡板打开和关闭。
图3A示出了本发明的替代实施例,其中提供预处理单元70以在环境气流进入第一空气室之前冷却环境气流。该预处理单元可以是任何已知类型的热交换器,包括例如焓轮72。
如图所示,环境气流在进入蒸发器26之前进入焓轮72,并且被冷却。焓轮通过由单独的管道系统从封闭区移除的返回空气而再生,然后被排放到大气中。
图3A还示出了第三空气室可以在其排放端80处延伸以将旁路空气直接供应到封闭区,而不是在第一空气室中混合旁路空气。
图4A和4B示出本发明的另一实施例,其适于将离开冷凝器28的空气室18中的加热空气的一部分引导到第三空气室55中。这是通过使用可选择性操作的挡板57来实现的,该挡板允许来自冷凝器28的加热空气中的一些进入空气室55以加热或替换通常在该空气室中的环境空气。当外部空气温度处于或低于旁路空气被设计成提供的温度时,将通常操作挡板57。
尽管在此已经参考附图描述了本发明的说明性实施例,但是应当理解,本发明不限于这些精确的实施例,而是本领域技术人员可以在不脱离本发明的范围或精神的情况下在其中进行各种改变和修改。

8.一种用于调节用于供应到封闭区的环境空气的方法,包括以下步骤:
用制冷系统的冷却盘管冷却第一环境供应气流,然后使冷却的环境供应气流通过旋转的干燥剂轮的一区段以降低第一环境供应气流的水分含量,并将如此处理的空气传送到封闭区;
通过用所述制冷系统的冷凝盘管加热第二环境气流并使加热的所述第二环境气流通过所述干燥剂轮的再生区段来再生所述干燥剂轮;以及
选择性地冷却不在所述第一空气室中进行处理的旁路空气室中的环境空气的供应,以及将冷却的空气从所述旁路空气室供应到所述封闭区。
9.根据权利要求8所述的方法,其中,所述旁路空气室中的环境空气是独立于所述第一空气室和所述第二空气室中的气流的第三环境气流。
10.根据权利要求8所述的方法,其中,所述旁路空气室中的环境空气在所述第一空气室中的蒸发器盘管的上游从所述第一空气室中的环境空气供应。
11.根据权利要求9所述的方法,其中,所述第三空气室中的环境空气在被供应到所述封闭区之前在所述干燥剂轮的下游被供应到所述第一空气室,并且与离开所述干燥剂轮的处理区段的空气混合。
12.根据权利要求8所述的方法,其中,冷却所述旁路空气室中的环境空气的步骤包括使用所述旁路空气室中的第二蒸发器盘管的步骤,所述第二蒸发器盘管独立于所述第一空气室中的蒸发器盘管。
13.根据权利要求8所述的方法,其中,冷却所述旁路空气室中的环境空气的步骤包括使用冷却水盘管冷却其中的环境空气的步骤。
14.根据权利要求8所述的方法,所述方法还包括预处理供应到所述第一空气室的环境空气的步骤。
15.根据权利要求1所述的系统,其中,用于选择性地冷却旁路气流的装置是冷却水盘管。
