为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述。
特斯拉阀通过流体离散与汇聚时不同的压降特性,其可以在一个流通方向上提供相较于另一个方向更高的压降,使流体沿其中一个方向流动会较为顺利,沿另一个方向会较为困难。特斯拉阀保证在逆压未超过临界值之前,内部无流体通过。其通过自身结构来限制流体流向,没有运动部件和控制部件,具有无磨损,寿命长等特性。本实施例新风系统在出风风道上设置特斯拉阀,通过特斯拉阀限制室外空气通过出风风道进入室内,而在室内压力大于室外(新风风道的控制阀打开且风机工作)时,将室内空气排出至室外,实现室内新风的目的。
下面通过几个实施例进行具体说明:
实施例一
如图1所示,本实施例的新风系统包括新风风道1和出风风道2,在新风风道1上设置有新风控制阀11和新风风机12,在出风风道2上设置特斯拉阀21。
下面对新风风道1和出风风道2进行具体说明:
新风风道1一般安装在建筑物腔体内,用于将室外的空气传导至室内。
新风风道1包括进风端13和出风端14,进风端13位于室外侧,出风端14位于室内侧。
为了保证从室外进入室内的空气的洁净程度,优选在新风风道1的进风端设置有过滤装置。
新风控制阀11装配在新风风道1内,新风控制阀11用于打开或关闭新风风道1。
新风控制阀11一般为风门,新风控制阀11打开时,新风风道1导通,新风控制阀11关闭时,新风风道1截止。
新风风机12装配在新风风道1上,用于提供空气流动的动力。一般在新风控制阀11打开时,新风风机12启动,以将室外空气引入室内,在新风控制阀11关闭时,新风风机12关闭。

出风风道2一般安装在建筑物腔体内,出风风道2包括进风端22和出风端23,进风端22位于室内侧,出风端23位于室外侧。
在进风端22和出风端23上均设置有与特斯拉阀21连通的通孔。
本实施例的出风风道2包括一个特斯拉阀21。
特斯拉阀21由于其自身特性具有正向流动方向和逆向流动方向,其中,正向流动方向是指压降较低的方向,逆向流动方向是指压降较高的方向,在正向流动方向上的流动较为顺利,在逆向流动方向上的流动较为困难需要较高的压力才能够导通。
在室内至室外的方向上,特斯拉阀21为正向流动方向,此种设置方式,室内空气能够比较顺畅地流动到室外,室外空气流动至室内则比较困难,因而,本实施例能够保障出风顺畅,并且还可避免室外空气通过出风通道2进入室内。
本实施例在新风控制阀11打开,新风风机12工作时,新风风道1将室外空气引入室内,使得室内气压增大,室内的浊气通过出风风道2的特斯拉阀21排出室外。
当然,为了避免室内热量的流失,还可在新风风道1和出风风道2之间增加换热器。
新风系统包括控制器,用于在接收新风开启控制信号时控制新风控制阀11打开、新风风机12启动,新风风道1将室外空气引入室内,使得室内气压增大,由于室内气压增大大于室外气压,室内的浊气可通过出风风道2的特斯拉阀21排出室外,实现室内新风功能。控制器还用于在接收新风关闭控制信号时控制新风控制阀11关闭、新风风机12关闭,此时,室外空气无法经过新风风道1进入室内,由于特斯拉阀21的特性,室外空气也无法经过出风风道2进入室内,保证了室内的相对封闭,保证空调效果。

本实施例的出风风道2包括三个并联的特斯拉阀21。
特斯拉阀21由于其自身特性具有正向流动方向和逆向流动方向,其中,正向流动方向是指压降较低的方向,逆向流动方向是指压降较高的方向,在正向流动方向上的流动较为顺利,在逆向流动方向上的流动较为困难需要较高的压力才能够导通。

本实施例还提出了一种空调器,空调器包括空调本体和上述的新风系统。
实施例五
如图5所示,本实施例的新风系统包括新风风道1和出风风道2,在新风风道1上设置有新风控制阀11和新风风机12,在出风风道2上设置特斯拉阀组。
下面对新风风道1和出风风道2进行具体说明:
新风风道1一般安装在建筑物腔体内,用于将室外的空气传导至室内。
新风风道1包括进风端13和出风端14,进风端13位于室外侧,出风端14位于室内侧。
为了保证从室外进入室内的空气的洁净程度,优选在新风风道1的进风端设置有过滤装置。
新风控制阀11装配在新风风道1内,新风控制阀11用于打开或关闭新风风道1。
新风控制阀11一般为风门,新风控制阀11打开时,新风风道1导通,新风控制阀11关闭时,新风风道1截止。
新风风机12装配在新风风道1上,用于提供空气流动的动力。一般在新风控制阀11打开时,新风风机12启动,以将室外空气引入室内,在新风控制阀11关闭时,新风风机12关闭。
出风风道2包括特斯拉阀组,用于将室内的空气传导至室外。
出风风道2一般安装在建筑物腔体内,出风风道2包括进风端22和出风端23,进风端22位于室内侧,出风端23位于室外侧。
在进风端22和出风端23上均设置有与特斯拉阀21连通的通孔。
出风风道2包括一个特斯拉阀组,特斯拉阀组为至少两个串联的特斯拉阀。
特斯拉阀由于其自身特性具有正向流动方向和逆向流动方向,其中,正向流动方向是指压降较低的方向,逆向流动方向是指压降较高的方向,在正向流动方向上的流动较为顺利,在逆向流动方向上的流动较为困难需要较高的压力才能够导通。
在室内至室外的方向上,至少两个串联的所述特斯拉阀的流动方向相反。
优选的,在室内至室外的方向上,特斯拉阀的流动方向为正向流动方向和反向流动方向。
本实施例的出风风道2包括一个特斯拉阀组,特斯拉阀组包括两个串联的第一特斯拉阀211和第二特斯拉法212,第一特斯拉阀211靠近室内,第二特斯拉阀212靠近室外,第一特斯拉阀211的流动方向为正向流动方向,第二特斯拉阀212的流动方向为反向流动方向。
此种设置方式,通过利用特斯拉阀在压力未达到一定值时的单向流通特性,这两个反向串联的特斯拉阀就组成了一个双向的压力开关通道,当压力值低于特斯拉阀的系统阻力时,出风通道2内无气流经过。具体的,当空调在室内正常运行不开启新风功能时,室内气压接近于室外气压,出风通道2两侧气压差不足以克服特斯拉阀的系统阻力,此时新风通道内没有气流通过/气流通过量非常小,无需担心房间内的冷气会跑到房间外,造成制冷量浪费;在开启新风功能时,室内气压大于室外气压并克服特斯拉阀的阻力时,能够实现室内浊气通过出风风道2排出,因而,本实施例在新风功能时能够保障出风顺畅,另外,室外气压一般不会高于室内气压,本实施例还可避免室外空气通过出风通道2进入室内。
本实施例在新风控制阀11打开,新风风机12工作时,新风风道1将室外空气引入室内,使得室内气压增大,室内的浊气通过出风风道2的特斯拉阀组排出室外。
当然,为了避免室内热量的流失,还可在新风风道1和出风风道2之间增加换热器。
新风系统包括控制器,用于在接收新风开启控制信号时控制新风控制阀11打开、新风风机12启动,新风风道1将室外空气引入室内,使得室内气压增大,由于室内气压增大大于室外气压,室内的浊气可通过出风风道2的特斯拉阀组排出室外,实现室内新风功能。控制器还用于在接收新风关闭控制信号时控制新风控制阀11关闭、新风风机12关闭,此时,室外空气无法经过新风风道1进入室内,室内空气也无法经过新风风道1进入室外;室内室外气压基本相同,由于特斯拉阀的特性,室外空气无法经过出风风道2进入室内,室内空气也无法通过特斯拉阀组进入室外,保证了室内的相对封闭,保证空调效果。
本实施例还提出了一种空调器,空调器包括空调本体和上述的新风系统。
实施例六
如图6所示,本实施例的新风系统包括新风风道1和出风风道2,在新风风道1上设置有新风控制阀11和新风风机12,在出风风道2上设置特斯拉阀组。
下面对新风风道1和出风风道2进行具体说明:
新风风道1一般安装在建筑物腔体内,用于将室外的空气传导至室内。
新风风道1包括进风端13和出风端14,进风端13位于室外侧,出风端14位于室内侧。
为了保证从室外进入室内的空气的洁净程度,优选在新风风道1的进风端设置有过滤装置。
新风控制阀11装配在新风风道1内,新风控制阀11用于打开或关闭新风风道1。
新风控制阀11一般为风门,新风控制阀11打开时,新风风道1导通,新风控制阀11关闭时,新风风道1截止。
新风风机12装配在新风风道1上,用于提供空气流动的动力。一般在新风控制阀11打开时,新风风机12启动,以将室外空气引入室内,在新风控制阀11关闭时,新风风机12关闭。
出风风道2包括特斯拉阀组,用于将室内的空气传导至室外。
出风风道2一般安装在建筑物腔体内,出风风道2包括进风端22和出风端23,进风端22位于室内侧,出风端23位于室外侧。
在进风端22和出风端23上均设置有与特斯拉阀连通的通孔。
由于特斯拉阀的管径一般较细,为了提高换新风效率,出风风道包括多个并联的特斯拉阀组,以使得进风量与出风量相适配。每个特斯拉阀组为至少两个串联的特斯拉阀。
特斯拉阀由于其自身特性具有正向流动方向和逆向流动方向,其中,正向流动方向是指压降较低的方向,逆向流动方向是指压降较高的方向,在正向流动方向上的流动较为顺利,在逆向流动方向上的流动较为困难需要较高的压力才能够导通。
在室内至室外的方向上,至少两个串联的所述特斯拉阀的流动方向相反。
优选的,在室内至室外的方向上,特斯拉阀的流动方向为正向流动方向和反向流动方向。
本实施例的出风风道2包括三个特斯拉阀组,每个特斯拉阀组包括两个串联的第一特斯拉阀211和第二特斯拉法212,第一特斯拉阀211靠近室内,第二特斯拉阀212靠近室外,第一特斯拉阀211的流动方向为正向流动方向,第二特斯拉阀212的流动方向为反向流动方向。
此种设置方式,通过利用特斯拉阀在压力未达到一定值时的单向流通特性,这两个反向串联的特斯拉阀就组成了一个双向的压力开关通道,当压力值低于特斯拉阀的系统阻力时,出风通道2内无气流经过。具体的,当空调在室内正常运行不开启新风功能时,室内气压接近于室外气压,出风通道2两侧气压差不足以克服特斯拉阀的系统阻力,此时新风通道内没有气流通过/气流通过量非常小,无需担心房间内的冷气会跑到房间外,造成制冷量浪费;在开启新风功能时,室内气压大于室外气压并克服特斯拉阀的阻力时,能够实现室内浊气通过出风风道2排出,因而,本实施例在新风功能时能够保障出风顺畅,另外,室外气压一般不会高于室内气压,本实施例还可避免室外空气通过出风通道2进入室内。
本实施例在新风控制阀11打开,新风风机12工作时,新风风道1将室外空气引入室内,使得室内气压增大,室内的浊气通过出风风道2的特斯拉阀组排出室外。
当然,为了避免室内热量的流失,还可在新风风道1和出风风道2之间增加换热器。
新风系统包括控制器,用于在接收新风开启控制信号时控制新风控制阀11打开、新风风机12启动,新风风道1将室外空气引入室内,使得室内气压增大,由于室内气压增大大于室外气压,室内的浊气可通过出风风道2的特斯拉阀组排出室外,实现室内新风功能。控制器还用于在接收新风关闭控制信号时控制新风控制阀11关闭、新风风机12关闭,此时,室外空气无法经过新风风道1进入室内,室内空气也无法经过新风风道1进入室外;室内室外气压基本相同,由于特斯拉阀的特性,室外空气无法经过出风风道2进入室内,室内空气也无法通过特斯拉阀组进入室外,保证了室内的相对封闭,保证空调效果。
