技术领域
本申请涉及空气调节技术领域,特别涉及一种窗式空调器。
背景技术
现在生活中,人们对于新风的要求越来越多,PTAC(Packaged Terminal Air Conditioner,包装末端空调设备)窗机作为美国市场中,中高端酒店宾馆最常使用的制冷系统同样也有很强烈的需求。然而现在人们不仅要求新风,而且对新风的舒适度又提出了新的需求,这样市场上即出现了一批新风加新风除湿的PTAC,但是这种PTAC为了满足除湿新风的需求,只是在原有的空调系统中追加了独立的除湿模块,并没有做到和原来的制冷系统进行统合,这样必然要使用双压缩机,双制冷系统来满足。也就是一个空调器,两个制冷系统,包括两个压缩机,两个电机,两个蒸发器,两个冷凝器,两个毛细管。这种双系统带来的弊端就是成本高,能效低,噪音大、生产工艺以及效率差。
而且新风吹到室内侧,虽然新风是经过除湿的,但是由于风量不是很大,并不能改变整个房间内的空气效果。即使PTAC开了除湿功能,但是经过除湿的室内风,温度会很低,吹出后用户感觉很不舒适。

本申请提出一种窗式空调器。
在本申请实施例中,如图1至图6所示,该窗式空调器包括壳体100、室内侧换热器200及新风装置300。所述壳体100内形成有室内侧风道110。室内侧换热器200设于所述壳体100内,所述室内侧换热器200包括沿所述室内侧风道110的进风方向层叠设置的第一室内换热器210及第二室内换热器220,窗式空调器具有恒温除湿模式,在恒温除湿模式下,所述第一室内换热器210及所述第二室内换热器220的其中一者处于制热模式,另一者处于制冷模式。新风装置300用于向所述室内侧风道110输送新风,所述新风装置300具有与室外连通的新风入口310、与所述室内侧风道110连通的新风出口320、连通所述新风入口310和所述新风出口320的新风风道330。
在本实施例中,壳体100的形状可以呈方形、筒形等,可根据具体使用需求进行选择,在此不做具体限定。通常,为了方便制造和成型,壳体100的形状大致呈方形设置。室内侧风道110的横截面形状可以呈矩形、圆形、异形等,在此不做具体限定。室内侧风道110的延伸方向通常与壳体100的长度方向一致。需要说明的是,第一室内换热器210及第二室内换热器220层叠设置,则两者的换热面可以紧贴设置,也可以呈一定的间隙。
可以理解的是,壳体100上设有室内进风口121及室内出风口122,室内侧风道110的进风端与室内进风口121连通,室内侧风道110的出风端与室内出风口122连通。室内进风口121及室内出风口122均可以开设在壳体100的前侧壁面。或者使得室内进风口121位于壳体100的前侧壁面,室内出风口位于壳体100的顶面。还可以使得室内出风口位于122位于壳体的前侧壁面与顶面的交界处。室内进风口121也可以开设在壳体100的左右两侧壁面。具体可根据使用需求及室内风机125的类型进行选择和设计。室内侧风道110内还可以设置室内风机125,该室内风机125可以是离心风机或贯流风机等。通过使得第一室内换热器210及第二室内换热器220沿室内侧风道110的进风方向层叠设置,则能够在室内风机125的作用下,先将新风风道330的新风气流从室内出风口122吹出,新风在室内与室内风混合,随后室内风机125将混合气流从室内进风口121引入,并依次经过第一室内换热器210及第二室内换热器220后,再从室内出风口122吹出。如此,不光能够对新风进行恒温除湿,还能够将室内风进行循环恒温除湿,使得整体的恒温除湿效果更佳。
在一实施例中,壳体100还设有与室内侧风道110连通的室内进风口121和室内出风口122,室内侧风道110内设有室内风机125,室内出风口122位于室内进风口121的上方。如此,室内进风口121及室内出风口122均可以开设在壳体100的前侧壁面,并使得室内出风口122位于室内进风口121的上方。也可以将室内进风口121设于壳体100的前侧壁面,将室内出风口122设置在壳体100的顶面。或者,还可以将室内进风口121设于壳体100的前侧壁面,将室内出风口122设于壳体100的前侧壁面与顶面的交界处,使得出风口斜向上出风。通过使得室内出风口122设于室内进风口121的上方,一方面能够便于室内侧换热器200对应室内进风口设置,另一方面,当室内风机125将新风由室内出风口122送出时,由于新风的湿度大,从室内出风口122吹出的新风气流会向下流通,则使得新风与室内风的混流效果好,且新风更易被室内风机125从室内出风口122下方的室内进风口121吸入室内侧风道110内进行恒温除湿。
具体而言,室内出风口122的送风方向与水平面的夹角大于0度,且小90度。则使得室内出风口122的送风方向呈斜上方吹出。具体地,室内出风口122的送风 方向与水平面的夹角可以为10度、20度、35度、45度、60度、70度、80度等。使得室内出风口122向斜上方送风,一方面能够避免风直吹用户和天花板,另一方面使得气流能够吹得更远,从而使得混流效果更好,进而使得室内温度分布更加均匀。可选地,室内出风口122的送风方向与水平面的夹角为45度。如此,便于成型和制造,且使得整体一致性更好。
新风入口310及新风出口320可以为矩形、圆形、长条形、椭圆形,也可以为多个微孔,在此不做具体限定。新风装置300用于向室内侧风道110输送新风,则可以在新风风道330内设置新风风机,用于将气流从新风入口310引入室内侧风道110内。还可以仅利用室内风机123的负压,通过将室外气流压入室内侧风道110。此时,新风出口320应设置在室内风机123的进风侧。判断窗式空调器需要制冷还是恒温除湿,可以通过室内的温度感温装置和湿度感知装置共同来判断。
需要说明的是,窗式空调器除了具有恒温除湿模式外,还可以有单独制冷、单独制热等模式。在窗式空调器处于恒温除湿模式下,可以使得第一室内换热器210处于制冷模式(作为蒸发器),则第二室内换热器220处于制热模式(作为冷凝器),或使得第一室内换热器210处于制热模式,第二室内换热器220处于制冷模式。如此,当新风进入室内侧风道110,并由室内出风口122吹出后,室内风及新风的混合气流能够重新被室内风机123吸入室内侧风道110,然后通过第一室内换热器210除湿\加热,以及通过第二室内换热器220加热\除湿,进而达到恒温除湿的目的,使得室内风及新风除湿后达到舒适的温度。为了使得除湿的效果更佳,使得气流先经过冷凝器加热后,再经过蒸发器除湿。也即,在恒温除湿模式时,使得第一室内换热器210为冷凝器,第二室内换热器220为蒸发器。
可以理解的是,第一室内换热器210及第二室内换热器220的换热模式还可以相同,则在窗式空调器需要单独制冷或制热时,可以使得第一室内换热器210和第二换热器同时处于制冷模式(同时作为蒸发器)或制热模式(同时作为冷凝器)。如此,经过第一室内换热器210及第二室内换热器220双重降温或升温,从而能够使得室内快速降温或升温,满足用户需要快速制热或制热的需求。
本申请窗式空调器通过在室内侧风道110的进风方向层叠设置第一室内换热器210及第二室内换热器220,且使得第一室内换热器210与第二室内换热器220的换热模式可相反,同时使得新风风道330的新风出口520与室内侧风道110连通。如此,第一室内换热器210及第二室内换热器220可以设置成一个为制冷模式,另一个为制热模式,如此,新风和室内风均能够被除湿和加热,不仅能将所有的室内风重新除湿,提高了除湿效率,且能够达到恒温除湿的目的,使得窗式空调器在除湿模式下整个室内温度不会下降,进而使用户不仅能感受到新风。而且经过除湿的风温度很舒适,不会有凉风感受。同时,除湿时能够充分利用室内换热器,不用另外设置新风冷凝器及新风蒸发器,则大大降低了制造成本及功率。同时,除湿系统及换热系统可以使用一个压缩机600,则使得整机的占用空间小,噪音小,生产工艺及效率得到了提升。
具体而言,请参照图2及图6,所述壳体100包括室内壳120,所述室内壳120形成有所述室内侧风道110,所述新风出口520设于所述室内壳120的后侧壁面,所述室内进风口121设于所述室内壳120的前侧壁面,所述第一室内换热器210与所述第二室内换热器220沿前后方向层叠设置。
在本实施例中,室内壳120可以直接由壳体100的一部份形成,也可以是单独设置的壳体100结构,此时,室内壳120设置在壳体100内。新风出口520及室内进风口121的形状可以为矩形、圆形、长条形、椭圆形,也可以为多个微孔,在此不做具体限定。通过使得室内进风口121设置在壳体100的前侧壁面,新风出口320设置在室内壳120的后侧壁面,则新风出口520与室内进风口121呈相对设置,均位于室内风机125的进风侧。如此,室内风机125能够更加有效的将新风及室内风吸入室内侧风道110内进行换热。且室内进风口121设置在前侧壁面,使得室内侧风道110能够流入大量的室内气流。第一室内换热器210的换热面可以对应室内进风口121设置,则从进风口流入的气流能够快速的流入第一室内换热器210及第二室内换热器220中进行换热。使得第一室内换热器210及第二室内换热器220呈前后层叠设置,则使得整体结构更加紧凑,从而减小室内侧换热器200的占用空间,进而减小整机体积。室内出风口122可以设置在室内壳120的顶部和/或侧面。
在一实施例中,如图4及图5所示,所述壳体100内还形成有室外侧风道130,所述窗式空调器还包括设于所述室外侧风道130内的室外换热器400及室外风机500,所述室外侧风道130的出风侧与所述新风风道330相连通,所述室外风机500用于向所述室外侧风道130及所述新风风道330内送风。
在本实施例中,可以理解的是,壳体100上设有室外进风口170及室外出风口160,室外侧风道130的进风端与室外进风口170连通,室外侧风道130的出风端与室外出风口160连通。室外侧风道130的横截面形状可以呈矩形、圆形、异形等,在此不做具体限定。室外侧风道130的延伸方向通常与壳体100的长度方向一致。室外风机500可以为轴流风机。室外侧风道130的出风侧,指的是室外风机500的出风端。通过将室外侧风道130的出风侧与新风风道330相连通,则能够充分利用室外风机500,室外风机500将室外气流吹向室外出风口160的同时能够吹向新风风道330。如此,新风风道330内不用另外设置新风风机,则节约一个风机,降低整体成本。通过室外侧风道130流入新风风道330内的气流,可以为经过室外换热器400换热后的气流,也可以为换热之前的气流。如使得新风风道330内流入的气流为经过室外换热器400换热后的气流,则还能够对气流进行加热,则室内冷凝器的功率不用设置很高,从而能够提高能效。
在一实施例中,如图1所示,所述壳体100具有两相对的侧壁及连接两所述侧壁的后端壁,所述后端壁设有与所述室外侧风道130的出风端连通的室外出风口160,至少一所述侧壁设有与所述室外侧风道130的进风端连通的室外进风口170。如此,气流从壳体100侧壁上的室外进风口170进入,经室外风机500抽吸至室外侧风道130内,对室外换热器400散热后从室外出风口160流出。使得室外进风口170及室外出风口160的布局更加合理。在其他实施例中,室外进风口170也可以设置在后端壁上。
具体地,请参照图5及图6,所述壳体100还包括室外壳140,所述室外壳140形成有所述室外侧风道130,所述新风装置300包括新风壳340,所述新风壳340形成有所述新风风道330,所述新风壳340连接于所述室外壳140,所述新风壳340与所述室外壳140的连接处形成所述新风入口310。室外壳140可以直接由壳体100的一部份形成,也可以是单独设置的壳体100结构,此时,室外壳140设置在壳 体100内。新风壳340的内腔形成新风风道330,新风风道330的横截面可以呈矩形、圆形、椭圆形等,在此不作具体限定。新风入口310的形状可以为圆形、矩形、椭圆形等,在此不做具体限定。新风壳340与室外壳140的连接处形成新风入口310,则新风风道330内的气流均从室外侧风道130流入,从而使得室外风机500驱动新风流入新风风道330的效果更佳。可选地,为了便于新风的导入,可以在新风入口310处设置导风百叶。
在一实施例中,如图4及图5所示,所述新风壳340设于所述室外换热器400与所述室内侧换热器200之间。通过使得新风壳340设置在室外换热器400与室内侧换热器200之间,一方面使得整体的结构更加紧凑,节约壳体100内的空间;另一方面,使得新风风道330的长度更短,也即新风从室外侧风道130流向室内侧风道110的路径更短,如此,使得风损更小,风速及风量更大、气流流入频率快。
在上述实施例的基础上,进一步地,请参照图4,所述新风壳340的新风入口310的过风面积小于所述新风壳340的新风出口320的过风面积。如此,使得新风出口320的过风面积大,则使得足够的新风能够吹向室内侧风道110。而通过使得新风入口310的过风面积小,则能够方便新风壳340与室外壳140的安装。
进一步地,所述新风壳340自所述新风入口310向所述新风出口320至少部分呈渐扩设置。新风壳340可以自新风入口310向新风出口320均呈渐扩设置,也可以仅在中段、靠近新风入口310的一段或靠近新风出风的一段呈渐扩设置。通过使得新风壳340至少部分呈渐扩设置,则在新风从新风入口310向新风出口320流动时,能够在渐扩段处扩流,从而有效的减小噪音,且使得气流的流通更加顺畅,满足新风流量的需求。
在一较佳实施例中,请再次参照图4,所述新风壳340至少一内侧壁面呈弧面341,所述弧面341自所述新风壳340外侧向所述新风壳340内侧呈内凹设置。当新风壳340呈方形设置时,其具有多个内侧壁面,则其中至少一个内侧壁面呈弧面341。而当新风壳340呈圆形设置,其仅具有一个内侧壁面,则新风壳340的内侧壁面均呈弧面341。通过使得新风壳340至少一内侧壁面呈弧面341,则使得气流的流通更加顺畅,减小风阻及风损。使得弧面341自新风壳340外侧向新风壳340内侧呈内凹设置,相比于外凸设置,能够避免气流在新风风道330内形成紊流, 进一步降低噪音。
在一实施例中,如图2、图4及图6所示,所述壳体100包括底盘150,所述新风装置300安装于所述底盘150,所述窗式空调器还包括安装于所述底盘150上的压缩机600,所述新风装置300与所述压缩机600分设于所述底盘150长度方向上的两侧。底盘150为压缩机600、换热器等结构提供安装和支撑。由于压缩机600的占用空间大、且重量较大。通过使得新风装置300及压缩分设在底盘150长度方向上的两侧,一方面使得布局更加合理,整体排布更加紧凑,充分利用底盘150上的安装空间,另一方面,使得底盘150上的重量分布更加均匀,防止因重力分布不均匀造成底盘150变形,且便于整机的安装。
以下具体介绍整个窗式空调器的工作系统。
在一实施例中,请参照图7,所述窗式空调器还包括压缩机600、室外换热器400及冷媒循环管路;
所述压缩机600的冷媒出口设置有排出管610,冷媒入口设置有吸入管620;
所述排出管610、所述室外换热器400、所述第一室内换热器210、所述第二室内换热器220、所述吸入管620通过所述冷媒循环管路依次连通。
在本实施例中,压缩机600可以为变频式压缩机600或定频式压缩机600。通过使得压缩机600为变频式压缩机600,能够更佳的实现制冷及恒温除湿双系统,节约了一个压缩机600,从而使得整体结构更加简单,降低成本和功率,大大提高了能效。可以理解的是,可以在室外换热器400与第一室内换热器210之间的冷媒循环管路上设置第一阀940,在第一室内换热器210与第二室内换热器220之间的冷媒循环管路上设置第二阀950。第一阀940及第二阀950可以为电磁阀、电子膨胀阀或节流阀,能够控制其所在配管的通断或流量。通过设置第一阀940及第二阀950,能够控制冷媒是否流入第一室内换热器210及第二室内换热器220,从而控制第一室内换热器210及第二室内换热器220是否参与制冷或制热。
当需要开启除湿模式时,压缩机600流出的高温冷媒进入到室外换热器400(冷凝器),从而室外换热器400出来的高温冷媒到达第一阀940,此时第一阀940可以全部或大部分打开,让第一室内换热器210的温度等于或略小于室外换热器400的温度,此时第一室内换热器210为冷凝器,起到加热气流的作用,然后流出 第一室内换热器210的次高温冷媒到达第二阀950,第二阀950起到毛细管节流的作用,节流后冷媒变为低温冷媒,流过第二室内换热器220,此时第二室内换热器220为蒸发器,起到降温的作用,也即除湿,从第二室内换热器220流出的冷媒再回到压缩机600。如此,新风和室内风混合后经过第一室内换热器210先加热,再经过第二室内换热器220降温除湿,进入室内侧风道110后由室内出风口122吹出,从而达到室内即除湿又不会吹冷风的目的,且除湿效果更佳。当然,第一室内换热器210可以作为蒸发器,第二室内换热器220作为冷凝器,则新风和室内风先降温除湿,再加热,同样可以实现恒温除湿的目的。
当不需要除湿,仅需开启制冷模式时,使得压缩机600流出的高温冷媒进入到室外换热器400(冷凝器),从而室外换热器400出来的高温冷媒到达第一阀940,此时第一阀940小部分打开起到毛细节流的作用,让第一室内换热器210的温度大大小于室外换热器400的温度,此时第一室内换热器210为蒸发器,起到降温的作用,然后流出第一室内换热器210的低温冷媒到达第二阀950,第二阀950完全或大部分开启,起到完全通过或者再节流的作用,通过第二阀950的冷媒流过第二室内换热器220,此时第二室内换热器220为蒸发器,起到二次降温的作用,从第二室内换热器220流出的冷媒再回到压缩机600。如此,新风和室内风混合后经过第一室内换热器210降温,然后经过第二室内换热器220二次降温,进入室内侧风道110后由室内出风口122吹出,从而能达到室内快速降温的目的。
在一实施例中,如图8及图9所示,所述冷媒循环管路包括连接所述排出管610与所述室外换热器400的第一配管710,以及连接所述吸入管620与所述第二室内换热器220的第二配管720;所述窗式空调器还包括切换装置800;
所述切换装置800串接于所述第一配管710及所述第二配管720上,所述切换装置800具有第一切换状态及第二切换状态;
在所述第一切换状态下,连接于所述切换装置800两端的所述第一配管710导通,连接于所述切换装置800两端的所述第二配管720导通;
在所述第二切换状态下,所述排出管610和所述切换装置800之间的第一配管710与所述切换装置800和所述第二室内换热器220之间的第二配管720导通,所述 室外换热器400和所述切换装置800之间的第一配管710与所述吸入管620和所述切换装置800之间的第二配管720导通。
在本实施例中,切换装置800可以为四通阀或其他使得冷媒不会同时进入室外换热器400和第二室内换热器220的切换装置800。通过切换装置800,能够使得空调器的功能增加。可以理解的是,切换装置800串接在第一配管710及第二配管720上,也即切换装置800的两端连通第一配管710,两端连通第二配管720。
在切换装置800处于第一切换状态时,压缩机600的排出管610流出的高温冷媒通过第一配管710流向室外换热器400,然后依次流入第一室内换热器210及第二室内换热器220,最后经第二配管720及吸入管620流回压缩机600。通过控制第一阀940及第二阀950的开度,能够控制第一室内换热器210为制冷状态或制热状态,从而能够控制整个系统处于恒温除湿模式或双重制冷系统。
在切换装置800处于第二切换状态时,压缩机600的排出管610流出的高温冷媒通过第一配管710及第二配管720流入第二室内换热器220,随后流向第一室内换热器210及室外换热器400,最后通过第一配管710、第二配管720及吸入管620流回压缩机600。可以通过控制第一阀940及第二阀950的开度,进而控制第一室内换热器210是处于制冷状态或制热状态,从而控制整个系统是处于除湿模式还是处于双重制热状态。第一阀940及第二阀950控制第一室内换热器210是处于制冷状态或制热状态,与上述没有切换状态的实施例相似,在此不做赘述。
在一实施例中,请再次参照图9,所述窗式空调器还包括冷媒散热器900,单向节流阀910、第一单向阀920和第二单向阀930;
所述冷媒散热器900串接在所述室外换热器400与所述第一室内换热器210之间的冷媒循环管路上;
所述单向节流阀910串接在所述室外换热器400与所述冷媒散热器900之间的冷媒循环管路上,所述单向节流阀910的入口邻近所述冷媒散热器900,所述单向阀的出口邻近所述室外换热器400;
所述冷媒循环管路还包括连接所述冷媒散热器900及所述第一室内换热器210的第三配管730及第四配管740,所述第三配管730及所述第四配管740并联设置;
所述第一单向阀920串接在所述第三配管730上,所述第一单向阀920的入口邻 近所述冷媒散热器900,所述第一单向阀920的出口邻近所述第一室内换热器210;
所述第二单向阀930串接在所述第四配管740上,所述第二单向阀930的入口邻近第一室内换热器210,所述第二单向阀930的出口邻近所述冷媒散热器900。
在本实施例中,需要说明的是,冷媒散热器900可以降低电控系统的温度,保证电控系统的安装性。单向节流阀910指的是,只在一个方向上对流路进行节流,而在另一方向上整个流路是完全流通的。单向节流阀910串接在室外换热器400与冷媒散热器900之间的冷媒循环管路上,且能够自冷媒散热器900向室外换热器400单向节流,从而可以能够控制进入室外换热器400的冷媒温度。第一单向阀920串接在第三配管730上,则能够自冷媒散热器900向第一室内换热器210单向导通流路。第二单向阀930串接在第四配管740上,则能够自第一室内换热器210向冷媒散热器900单向导通流路。通过设置单向节流阀910、第一单向阀920及第二单向阀930,能够保证经过冷媒散热器900的冷媒不低于环境温度。而通过设置冷媒散热器900、单向节流阀910、第一单向阀920及第二单向阀930,能够实现电控装置冷媒散热,改善凝露的作用。
以上所述仅为本申请的优选实施例,并非因此限制本申请的专利范围,凡是在本申请的发明构思下,利用本申请说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
