Description
技术领域
本发明涉及一种除湿换风机。
背景技术
在生产和生活环境中,空气的相对湿度具有相当重要的影响,空气的湿度过高,容易对各类生活用品造成影响,生活用品会变得容易腐烂,而人体处在空气湿度大的影响下,身体也会受影响,容易生病, 空气除湿的方法有很多种,冷冻除湿作为其中的一种,由于能耗小、操作简单、易于控制,得到了广泛的应用。冷冻除湿机就是采用冷冻除湿的原理,用制冷机作冷源,以直接蒸发式冷却器作冷却设备,把空气冷却到露点温度以下,析出大于饱和含湿量的水汽,降低空气的绝对含湿量,再加热冷却后的空气,从而降低空气的相对湿度,达到除湿目的,在夏天时,出风口出风温度通常都比较低,容易发生凝露现象,传统的冷冻类除湿机通常依靠再热盘管提高出风温度来解决这一问题,当机组内部装上热回收芯体时,***阻力变大,此时只有增加风机余压,导致电机能耗加大,机组噪音加大。
发明内容
本发明目的在于解决上述现有除湿机存在的功耗大、机组噪音较大的问题,提供了一种利用待除湿空气的热量对低温干燥空气进行回温的除湿换风机,具体由以下技术方案实现:
一种除湿换风机,具体包括壳体、热交换芯体以及表冷器,所述壳体的侧壁开设有新风入口以及干风出口,所述热交换芯体置于壳体的中部,热交换芯体的四周被板材分割形成湿风区、除湿区、干风区以及出风区;热交换芯体的内部具有互相进行热交换的若干湿风通道和热回收通道;所述新风入口设置于湿风区对应的壳体部分,所述干风出口设置于出风区对应的壳体部分,所述表冷器置于除湿区内,所述湿风通道连通湿风区与置于除湿区内的表冷器,所述除湿区与干风区连通,所述热回收通道连通干风区和出风区;驱动空气依次经由湿风区、湿风通道、表冷器、除湿区、干风区、热回收通道、出风区最终自干风出口排出的风机置于壳体内。
所述的除湿换风机,其进一步设计在于,所述热交换芯体由若干具有多个孔道的层板堆叠连接而成,相邻两个层板内的孔道互相交错并且分别连通湿风区与表冷器、干风区与出风区,形成所述的湿风通道和热回收通道。
所述的除湿换风机,其进一步设计在于,所述壳体的上部设有室内风区以及与室内风区相对的室内风入口,该室内风区内部设置有风机且通过第一阀门与湿风区连通。
所述的除湿换风机,其进一步设计在于,所述壳体的上部还设置有与所述室内风入口相对应的室内风出口,该室内风出口处设置有第二阀门。
所述的除湿换风机,其进一步设计在于,位于除湿区与干风区之间的板材上设有连通两区的通孔,该通孔处设置有风机;出风区内设置有与所述干风出口相对的风机;所述新风入口处设置有第三阀门。
本发明利用热回收芯体将具有较高温度的待除湿空气与除湿后生成的低温干燥空气进行热交换从而提高干燥空气的温度,无需使用再热盘管从而减少了风阻,从而可以使用功率较低的风机,达到了降低机组功耗,减轻噪音的目的。
在关闭第一阀门、开启第三阀门时,本发明能将室外新风除湿回温后送入室内;在开启第一阀门、关闭第二阀门以及第三阀门时,本发明能够将室内空气进行除湿回温循环;关闭第一阀门以及第三阀门,开启第二阀门时,本发明可以作为简单的换风机使用;综合本段所述,本发明可以根据室内外空气的温度湿度条件选择适用不同的换风功能,具有较好的通用性。
附图说明
图1为本发明的结构示意图。
图2为热交换芯体的结构示意图。
图3为本发明用作室内风除湿循环时风力流向图。
具体实施方式
以下结合说明书附图以及实施例对本发明进行进一步说明。
结合图1,该除湿换风机包括壳体1、热交换芯体2以及表冷器3,壳体的侧壁开设有新风入口11以及干风出口12,新风入口11处设置有第三阀门13;热交换芯体2置于壳体的中部,热交换芯体的四周被板材分割形成湿风区41、除湿区42、干风区43以及出风区44;热交换芯体2的内部具有互相进行热交换的若干湿风通道21和热回收通道22;新风入口11设置于湿风区41对应的壳体部分,干风出口12设置于出风区对应的壳体部分,表冷器3置于除湿区42内,湿风通道21连通湿风区41与置于除湿区内的表冷器3,位于除湿区与干风区之间的板材上设有连通两区的通孔,该通孔处设置有风机5,热回收通道22连通干风区43和出风区44;出风区内设置有与干风出口相对的风机5;在风机驱动下空气依次经由湿风区、湿风通道、表冷器、除湿区、干风区、热回收通道、出风区最终自干风出口排出。
壳体1的上部设有室内风区6以及与室内风区相对的室内风入口61,该室内风区内部设置有风机5且通过第一阀门62与湿风区41连通。壳体1的上部还设置有与室内风入口61相对应的室内风出口63,该室内风出口63处设置有第二阀门64。壳体1的下部设置有通过管路(图中未画出)与表冷器3连通的冷热源入口31及出口32。
如图2所示,热交换芯体2由若干具有多个孔道的层板23堆叠连接而成,相邻两个层板21内的孔道互相交错并且分别连通湿风区与表冷器、干风区与出风区,形成的湿风通道和热回收通道。
在风机的作用下湿风区的空气经由热回收芯体内的湿风通道进入进入位于除湿区内的表冷器,空气低温除湿之后通过干风区进入热回收芯体内的热回收通道与后续待除湿空气进行热交换抬高干燥空气的温度,最终由干风出口进入室内。
对照图1中壳体下部的空气流通线路,在室外空气较为清洁需要新风时,关闭第一阀门、开启第三阀门时,本发明能将室外新风除湿回温后送入室内。对照图1所示壳体上部的空气流通线路,关闭第一阀门以及第三阀门,开启第二阀门时,本发明可以作为简单的换风机使用。
对照图2所示壳体内空气流通线路,在室外空气较为污浊或者无需引入新风时,开启第一阀门、关闭第二阀门以及第三阀门时,本发明能够将室内空气进行除湿回温循环;
综上所述,本发明可以根据室内外空气的温度湿度条件选择适用不同的换风功能,具有较好的通用性。
