Description
本发明涉及换风***设计技术领域,特别涉及一种利用二次负压送入新风房间新风***及全屋新风***。
在建筑物包括住宅的通风***中,一种常用的负压通风方式是,采用负压主排风管和房间回风管抽风,依靠回风管负压动力来实现房间新风置换,减省了作为房间气流置换动力的风机,降低了新风***安装难度和安装工作量。但是,这种负压通风方式在失去房间内部气流置换的送风动力之后,为了防止房间内新风自新风口直奔回风口而发生新风短路,要求房间回风管管口与新风口相远设置(在水平方向和竖直方向都要尽可能拉开距离),致使回风管路长度增加、安装工作量增加、气流沿程阻力增加,并且在房间内通风气流主体四周,依然存在着大区域的通风盲区,如图1所示。
而另一种正负压结合的通风方式是,利用作为中央空调末端的房间门头风机盘管,使之房间内循环和新风置换“一机两用”。新风置换时来自住宅过道等公共空间的新风,通过新风连接管流入房间风机盘管被加压排出,新风获得动能射向对墙,压迫污浊空气流向房间回风管;这种有房间气流循环动力的房间新风置换方式,可以加大房间气流搅动幅度,大幅度减少通风盲区,新风置换效果好;并且房间回风管口可以任意设置,甚至设置在新风口附近也可以;但是,这种正负压结合通风方式,要将房间风机盘管设置房间空调内循环和新风置换“一机两用”专门模块,还要设置新风连接管,并且室内装潢时新风连接管要自过道向上穿越吊顶、再横向穿越房间门头上方的横梁,还要与风机盘管模块新风进风口精准对接组装,工程量大,安装精度要求比较高,如图2所示。

与现有技术相比,本发明存在以下技术效果:
1、加大了房间空气搅动、压缩了通风盲区
通过房间新风口与房间风机盘管吸风口相近设置、房间新风口与房间回风管的回风口相远设置,即房间新风口与吸风口之间的距离小于房间新风口与房间回风管的回风口之间的距离,有效利用了在房间回风管抽吸产生的一次负压基础上由与房间新风口相近设置的风机盘管吸风口抽吸产生的二次负压,使风机盘管吸风口处在房间最低压力区,在相近设置的房间新风口与风机盘管吸风口之间形成最大压力差,驱动门头新风快速流进房间,并由风机盘管吸入升压加速射向房间对面墙面,经对面墙面反射再回流房间下部,压迫房间污浊空气进入房间回风管,从而加大了房间空气搅动、消除了通风盲区;

房间新风口与风机盘管吸风口相近设置及房间新风口与房间回风管的回风口相远设置,都是无刚性连接的自由设置,只要保证房间新风口、风机盘管的吸风口、房间回风口三“口”之间的“远”“近”空间关系,就可以有效利用在房间回风管抽吸产生的一次负压基础上由与房间新风口相近设置的风机盘管吸风口抽吸产生的二次负压,拉动过道新风涌入房间,高质量实施房间新风置换,省去了复杂的穿越吊顶、横梁的新风连接管及其安装工程。
当然,实施本发明的任一产品并不一定需要同时达到以上所述的所有优点。
为了更清楚地说明本发明实施例的技术方案,下面将对实施例描述中所需要使用的附图作简单的介绍,显而易见,下面描述中的附图仅仅是本发明的一些实施例,对于本领域技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。附图中:

图12为本发明的优选实施例5提供的一种利用二次负压送入新风房间新风***及全屋新风***的结构示意图(新风通过送风管跨越一间房间送入套内)。
现状建筑物的内墙、外墙和门窗,将原来宽敞开放的建筑空间分隔成为若干空间单元。以住宅为例,内墙、外墙和门窗将原本宽敞开放的100㎡左右的建筑空间分隔成为客厅、卧室、书房、厨房、卫生间、储物间等若干功能单元,这些空间单元不仅与环境难以达成自然通风,甚至连强制通风也很难操作。
住宅通风面临着诸多阻力问题:外墙内墙多重墙体对气流阻隔,在住宅套内还存在多个障碍物后的通风盲区,还有为达到适宜的室内温度、湿度、洁净度目标而进行的新风过滤、热交换等等,所有这些都使得住宅通风需要对气流多次实施风机加压推动气流输送。
住宅通风的关键难点在于房间通风,因为,即使设置了全屋总进风模块和总排风模块,具备了将新风通过客厅过道送达各个房间门头房间新风口、将各个房间污浊空气通过房间回风管、总排风管抽出户外的条件,如果房间新风口没有接力送风动力,而是仅仅依靠客厅过道的送风正压和房间回风管负压动力来实现房间高效率新风置换,仍然是不可能的:首先,客厅过道存在大量对住宅外部环境的漏风渠道,导致自客厅过道送达各个房间门头的新风只能是1pa级的“微正压”而不可能是10
1pa、10
2pa级的“正压”,在这个“微正压”驱动下客厅过道新风穿过房间新风口时难以产生3m/s以上的速度和相应的动压头,难以对房间内部气流场产生大力度“搅动”;其次,由总排风模块、总排风管和房间回风管产生的房间负压,也不足以拉动房间新风口处的新风产生3m/s以上的速度和相应的动压头,特别是当房间回风管的回风口与房间新风口相近设置甚至同侧设置时,还将出现严重的新风短路,即房间新风口进入的新风气流,没有获得较高动压头使之涌入房间主体空间,而是沿着房间新风口与回风管的回风口之间的路程最短、阻力最小的路径直奔房间回风管口,大幅度降低了房间新风置换效果,浪费了新风资源,如图3所示。
本发明提供一种利用二次负压送入新风房间新风***及全屋新风***,针对上述“即便设置了全屋总进风模块和总排风模块,具备了将新风通过总进风模块和客厅过道送达各个房间新风口、将各个房间污浊空气通过房间回风管总排风管和总排风模块抽出户外的条件,房间新风口没有接力送风动力仅仅依靠客厅过道的送风正压和房间回风管负压动力仍然无法防止房间新风短路无法实现房间高效率新风置换”问题,以户式中央空调***或分体式空调器的室内机为基础兼并新风***,将户式中央空调***末端或分体式空调器的室内机即各个房间风机盘管的功能进行拓展,既作为房间空调内循环的动力,也作为房间新风置换的中继动力,实行内循环和新风置换“一机两用”;本发明不设置客厅过道等送风空间与房间风机盘管吸风口之间刚性新风连接管,保持房间风机盘管的空间设置自由度;本发明房间新风口可以设置风门,当打开风门时,实行内循环和新风置换“一机两用”,当关闭风门时,只实行 房间内循环;本发明只要求建立控制房间新风口、风机盘管吸风口、房间回风管的回风口三者之间的适当的空间相对关系,即要求房间新风口与风机盘管吸风口相近设置,房间新风口与房间回风管的回风口相远设置,即房间新风口与风机盘管吸风口之间的距离小于房间新风口与房间回风管的回风口之间的距离。
本发明一种利用二次负压送入新风房间新风***运行时,房间新风口风门打开、房间回风口对房间污浊空气进行抽排、房间风机盘管运行,房间回风口抽排在房间产生一次负压,在这一次负压基础上风机盘管运行在风机盘管吸风口产生二次负压,使风机盘管吸风口处在房间最低压力区,在相近设置的房间新风口与风机盘管吸风口之间形成大压力差,拉动新风快速涌入房间并被风机盘管吸风口吸入升压,从风机盘管的出风口高速射出,射出的新风气流经风机盘管对面的墙壁反射再回流至风机盘管所在侧,压迫房间污浊空气进入与房间新风口相远设置的房间负压回风口,形成房间高效率双向流新风置换效果。
以下将结合图4至图12对本发明提供的一种利用二次负压送入新风房间新风***及全屋新风***进行详细的描述,以下实施例在以本发明技术方案为前提下进行实施,给出了详细的实施方式和具体的操作过程,但本发明的保护范围不限于下述的实施例,本领域技术人员在不改变本发明精神和内容的范围内,能够对其进行修改和润色。

在本实施例中,所述房间新风口24上设有风门21,当所述风门21关闭时,在所述风机223的作用下,房间内的空气从所述吸风口222进入,经所述出风口221排出后,再进入所述吸风口222,实现房间内循环;

房间新风口24上可以设置风门21,也可以不设置风门21,可根据实际使用需求设定。如果房间新风口24上不设置风门21,那么房间新风***在运行时,新风置换与内循环同步进行。
所述壳体内还设有换热器,所述换热器与为其提供换热介质的循环机组连接。在本实施例中,风机盘管22为分体空调的室内机,所述室内机与所述 分体空调的室外机相连构成制冷剂循环回路。在所述风机223的作用下,空气从所述吸风口222进入到所述壳体内,穿过所述换热器后从所述出风口221排出。本实施例对空调的具体类型不做限制,如可以是中央空调,也可以是分体式空调器,还可以是中央空调与分体式空调器的组合体,如风机盘管为壁挂机、柜机、暗装风机盘管或明装风机盘管,室外机为中央空调水机室外机、中央空调氟机室外机或分体式空调器的室外机,各室内机与各室外机可随机组合。具体的,作为一种实施例,所述风机盘管为吊顶安装在房间内的中央空调水机末端的风机盘管或中央空调氟机末端的室内机,所述风机盘管为吊顶安装在房间内的中央空调水机末端的风机盘管或中央空调氟机末端的室内机,所述风机盘管与所述中央空调水机室外机相连构成冷热水循环回路,或与所述中央空调氟机室外机相连构成制冷剂循环回路。作为第二种实施例,所述风机盘管为安装在房间的内墙壁上的分体式空调器的室内壁挂机或吸顶安装在房间内的分体式空调器的室内风机盘管,室内壁挂机或室内风机盘管与所述分体式空调器的室外机相连构成制冷剂循环回路。综上可知,不管是哪种空调类型,都适用于本实施例提供的风机盘管22。
本实施例的风机盘管22以中央空调机组的末端为例,所述风机盘管22吊顶安装在房间1内,且靠近房门11的位置,所述风机盘管22靠近所述房间新风口24设置,所述房间回风管23的回风口远离所述房间新风口24设置,所述风机盘管22的出风口221高于所述吸风口222。
本实施例提供的利用二次负压送入新风房间新风***,以户式中央空调***为基础兼并新风***,将户式中央空调***末端即各个房间风机盘管22的功能进行拓展,既作为房间空调内循环的动力,也作为房间新风置换的中继动力,实行内循环和新风置换“一机两用”;本实施例不设置客厅过道等送风空间与房间风机盘管22吸风口222之间刚性新风连接管,保持房间风机盘管22的空间设置自由度;本实施例房间新风口24可以设置风门21,当打开风门21时,实行内循环和新风置换“一机两用”,当关闭风门21时,只实行内循环;本实施例要求建立控制房间新风口24、风机盘管22吸风口222、房间回风口231三者之间的适当的空间相对关系,即要求房间新风口24与风机盘管22吸风口 222相近设置,房间新风口24与房间回风口231相远设置,即房间新风口24与风机盘管22吸风口222之间的空气流通的距离小于房间新风口24与房间回风管23的回风口231之间的空气流通的距离。
本实施例提供的利用二次负压送入新风房间新风***的内循环运行时,风机盘管22启动运行,风机223将吸入的室内空气升压流过换热器进行降温除湿(或者加热升温),之后从风机盘管22的出风口221高位射出,经房间对面墙体(和/或门窗)反射再向风机盘管22所在一侧墙体回流,压迫室内下部空气从风机盘管22吸风口222补充进入风机盘管22,开始下一轮循环。房间空调内循环时空气压力分布:房间上部的气流压力高、房间下部的气流压力低,风机盘管22出风口221的气流压力最高、风机盘管22吸风口222的气流压力最低,如图4所示,图中,从左往右走的箭头线条为内循环房间上部气流走向,对应的中轴线上方的从左到右向下倾斜的直线为内循环房间上部气流的压力分布;从右往左走的箭头线条为内循环房间下部气流走向,对应的中轴线下方的从右到左向下倾斜的直线为内循环房间下部气流的压力分布。
本实施例提供的利用二次负压送入新风房间新风***的新风置换运行时,房间新风口24风门21打开、房间回风口231对房间污浊空气进行抽排、房间风机盘管22运行,房间回风口231抽排在房间产生一次负压,风机盘管22的吸风口222在房间回风口231抽吸产生的一次负压的基础上产生二次负压,使风机盘管22吸风口222处在房间最低压力区,在相近设置的房间新风口24与风机盘管22吸风口222之间形成大压力差,拉动新风快速涌入房间内并被风机盘管22的吸风口222吸入,升压后从风机盘管22的出风口221高速射出,射出的新风气流经对面墙体反射再回流房门所在内墙一侧,压迫房间内污浊空气进入与房间新风口24相远设置的房间负压回风口231,形成房间高效率双向流新风置换效果,如图5至图7所示。
在实施房间新风置换时,因为房间回风管23抽吸使得房间整体呈现负压,从而使风机盘管22吸入口222的负压比内循环时更低,房间内与房间外的压差更大,房间外新风涌入房间内的动力更大,有利于房间新风进入。房间外的新风从房间新风口24涌入房间的新风,就近被风机盘管22吸入口222吸入升压 排出,新风获得较高动能和动压头射向对面墙面,被对面墙面反射后回流房间下部,推动房间污浊空气流向房间回风管23的回风口231。
本实施例提供的利用二次负压送入新风房间新风***,最本质特征是房间回风管23的回风口231(即房间回风口231)抽排在房间内产生一次负压,风机盘管22的吸风口222在房间回风口231产生的一次负压的基础上产生二次负压,这两次负压叠加使风机盘管22的吸风口222处在房间内最低压力区,在相近设置的房间新风口24与风机盘管22吸风口222之间形成大压力差,拉动新风快速涌入房间,如图8所示。
在图8中,从左往右走的箭头线为房间上部气流走向,从右往左走的箭头线为房间下部气流走向;对应的横轴上方的从左到右向下倾斜的实线为内循环房间上部气流的压力分布,对应的横轴下方的从右到左向下倾斜的实线为内循环房间下部气流的压力分布;对应的横轴上方的从左到右向下倾斜的虚线为新风置换房间上部气流的压力分布,对应的横轴下方的从右到左向下倾斜的虚线为新风置换房间下部气流的压力分布。
显然,新风置换时,风机盘管22的吸风口222在房间回风口231产生的一次负压的基础上产生二次负压,这两次负压叠加使风机盘管22的吸风口222处在房间最低压力区,在相近设置的房间新风口24与风机盘管22吸风口222之间形成大压力差,拉动新风快速涌入房间。
实施例2
本实施例与实施例1都是将房间风机盘管22的功能进行拓展,既作为房间空调内循环的动力,也作为房间新风置换的中继动力,实行内循环和新风置换“一机两用”;本实施例不设置客厅过道等送风空间与房间风机盘管22吸风口222之间刚性新风连接管,保持房间风机盘管22的空间设置自由度;本实施例房间新风口24可以设置风门21,当打开风门21时,实行内循环和新风置换“一机两用”,当关闭风门21时,只实行内循环;本实施例要求建立控制房间新风口24、风机盘管22吸风口222、房间回风口231三者之间的适当的空间相对关系,即要求房间新风口24与风机盘管22吸风口222相近设置,房间新风口 24与房间回风口231相远设置,即房间新风口24与风机盘管22吸风口222之间的距离小于房间新风口24与房间回风管23的回风口231之间的距离。
本实施例的不同之处在于,房间风机盘管22'不是户式中央空调机组的末端,而是分体式房间空调器室内机,房间风机盘管22'安装在房间1的内墙壁上。在本实施例中,分体式房间空调器室内机可以与中央空调的室外机连接,也可以与分体式空调机的室外机连接。在本实施例中,只要是风机盘管22',能够吸排风推动室内空气循环,从而在相远设置的房间回风管23的回风口231抽吸房间污浊空气实施房间新风置换时能够在风机盘管22吸风口222产生更低的二次负压,从而在房间门头上的房间新风口24内外建立压差驱动过道新风涌入房间,就是全屋新风置换的中继动力,就是房间通风的主动力。
本实施例将无送风管双向流新风***,推广到采用分体式房间空调器的场景,扩大了无送风管双向流新风***的应用范围,如图9所示。

在房间回风管23的回风口231抽吸产生的一次负压基础上由与房间新风口相近设置的门头风机盘管22吸风口222抽吸产生的的二次负压下,风机盘管22吸风口222处在房间最低压力区,在相近设置的房间新风口24与风机盘管22吸风口222之间形成大压力差,门头新风通过房间新风口24快速涌进房间,并由风机盘管22吸入升压加速射向房间外墙侧,经外墙反射再回流房门所在内墙一侧,压迫房间污浊空气进入房间回风管23;
3、污浊空气排出段
进入房间回风管23的污浊空气,快速流入总排风管,进入排风模块5被排风风机再次升压,最后排往室外大气扩散。
