Description

一种车下安装的轨道车辆空调机组
本申请要求于2014年12月08日提交中国专利局、申请号为201410743312.1、发明名称为“一种车下安装的轨道车辆空调机组”，以及要求于2014年12月08日提交中国专利局、申请号为201420765292.3、发明名称为“一种车下安装的轨道车辆空调机组”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种空调机组，特别涉及一种车下安装的轨道车辆空调机组，属于轨道车辆空调技术领域。
背景技术
目前车辆空调机组安装方式主要分为车顶安装和车下安装两种，空调安装在车下有利于降低车辆重心，车辆高速运行时的平稳性相对较好。空调安装在车顶时，距离轨道面较高(约3.3m)，冷凝进风温度与大气温度接近，而大气温度在高温季节时最高不超过45℃，高温季节空调冷凝效果相对较好，可以输出较大的制冷量，制冷能力可以保证。但空调安装在车下后，不但会受车下设备安装空间的限制，而且空调距离轨道面较低(约0.5m)，在高温季节，由于地表辐射热及设备舱内设备散热影响，空调冷凝风温度较大气温度高约10℃，冷凝温度最高可达55℃，导致空调在高温季节由于冷凝效果差，空调制冷能力不能完全发挥，制冷效果差，车内温度偏高。
现有的车下安装的空调机组，如专利号为200820133582.0的中国专利“高速铁路车辆空调装置”中所公开的，空调机组包括壳体，在壳体内分成室内侧和室外侧，室外侧内安装冷凝器、压缩机及冷凝风机，其中，两台冷凝风机安装在壳体内的一侧，在壳体的侧壁上开有冷凝进风口，在壳体内的另一侧设置冷凝器，与冷凝器对应的壳体侧壁上开有冷凝出风口，空调冷凝进出风方向为从一侧裙板及设备舱内吸入空气，吸收冷凝器的热量后从另一侧裙板排出。此种结构的空调机组，由于受车下设备舱内设备 布置的影响，空调安装后的冷凝风量较设计值偏小，单侧进单侧出冷凝效果差，冷凝风量不能满足空调在高温制冷季节的要求，车内乘坐舒适性受到一定影响。而且，现有的单元式空调机组为沿车体长度方向安装布置，空调机组的两侧与裙板之间要留出空间以供气体流通，占用了较大的车下空间。
发明内容
本发明主要目的在于解决上述问题和不足，提供一种可以增大冷凝进风量，提高空调机组高温环境下制冷效率的车下安装的轨道车辆空调机组。
为实现上述目的，本发明的技术方案是：
一种车下安装的轨道车辆空调机组，为单元式空调机组，包括壳体，在壳体内分为室内侧和室外侧，在所述室外侧安装冷凝器、冷凝风机及压缩机，在所述壳体对应设备舱两侧裙板进风口的两个侧壁上开设冷凝进风口，在所述壳体的底壁上开设冷凝出风口，所述冷凝风机靠近底壁的冷凝出风口位置设置，所述冷凝器为两个，分别靠近两侧的所述冷凝进风口设置。
进一步，所述壳体在车体宽度方向上延长，所述壳体的两侧侧壁紧靠所述两侧裙板的进风口处设置。
进一步，所述压缩机为两台，分别安装于两侧的所述冷凝器与相应的壳体侧壁之间的空间内。
进一步，所述冷凝风机为两个，沿车体宽度方向并排设置在两个所述冷凝器之间。
进一步，所述壳体的两侧侧壁与所述裙板进风口之间设置有由连接板围成的风道，将所述裙板进风口与所述冷凝进风口连通。
进一步，在所述裙板的进风口处设置第一过滤装置。
进一步，在所述冷凝进风口处设置第二过滤装置。
进一步，所述空调机组壳体的底壁作为设备舱的底板设置，所述壳体的底壁与周围的设备舱底板之间固定连接。
进一步，所述冷凝器垂直所述壳体的底壁放置，或向车体中心线方向倾斜放置。
综上内容，本发明所述的一种车下安装的轨道车辆空调机组，与现有技术相比，具有如下优点：
(1)将冷凝器由一个增加为两个，将冷凝风机由侧面变更到底面，更改空调的冷凝进出风方向，将冷凝进风口设置在裙板两侧，将冷凝排风方向设置在空调机组底部，空调冷凝进风面积增加了1倍，从而增加空调冷凝风量，提升空调高温时的制冷效果，提高在高温环境中长时间运营时乘坐的舒适性。
(2)本发明从裙板两侧进风，加长了空调机组在车宽方向上的长度，与两侧裙板配合，使空调机组在车长方向变短，改变了现有技术中空调机组的结构和安装方式，不但可以保证进风量，还可以大幅节省车下空间。
(3)本发明将冷凝出风口开在空调机组底部，向下排风，可以避免空调机组的冷凝风排向设备舱内而使设备舱温度升高，影响其它设备的正常运行。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，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。

图2是本发明冷凝进出风方式示意图；
图3是本发明实施例二结构示意图；
图4是图3的A向视图。
如图1至图4所示，设备舱1，壳体2，室内侧3，室外侧4，蒸发器5，蒸发风机6，冷凝器7，冷凝风机8，压缩机9，送风口10，回风口11，冷凝进风口12，冷凝出风口13，裙板14，进风口15。
具体实施方式
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、完整的描 述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面结合附图与具体实施方式对本发明作进一步详细描述：
实施例一：
如图1所示，本发明提供的一种车下安装的轨道车辆空调机组，为单元式空调机组，整体安装于车下的设备舱1内，空调机组包括壳体2，在壳体2内分为室内侧3和室外侧4，在室内侧3安装蒸发器5、蒸发风机6等，在室外侧4内安装冷凝器7、冷凝风机8及压缩机9，室内侧3的壳体上开有送风口10和回风口11，在室外侧4的壳体上开有冷凝进风口12和冷凝出风口13。
为了实现设备舱1内设备的通风降温，在裙板14上都开有进风口15，在进风口15处设置有第一过滤装置，第一过滤装置为过滤网或者为机械式过滤器等，以实现有效过滤环境中沙尘等，对冷凝空气起到粗过滤的作用，保证空调机组的正常运行。本实施例中，对应两侧裙板14上的进风口15，在壳体2两侧的侧壁上分别开设冷凝进风口12，为进一步过滤细小的沙尘，在冷凝进风口12处还可以再设置第二过滤装置，第二过滤装置可以采用无纺布或不锈钢丝网等，用于二次过滤进入空调冷凝器7的空气，在壳体2的底壁上开冷凝出风口13，实现从壳体2的两侧进风及从壳体2的底部出风的冷凝进出风方式。本实施例中，在空调机组下方不单独设置设备舱1底板，壳体2的底壁作为设备舱1的底板19设置，使空调机组的冷凝出风直接排向车外，避免空调机组的冷凝出风排至设备舱1内而使设备舱温升升高，影响其它设备的正常运行。壳体2的底壁与周围的设备舱1底板之间固定连接，为保证设备舱1的密封性，防止沙尘等进入设备舱1，连接处可作密封处理。
在室外侧4内，冷凝器7、冷凝风机8及压缩机9均设置为两个。两个冷凝器7分别靠近两侧的冷凝进风口12设置，冷凝器7可以通过安装结构垂直固定在壳体2的底壁上，本实施例中，为了增大冷凝器的换热面积，将冷凝器7向车体中心线方向倾斜安装。两个冷凝风机8靠近底壁的冷凝出风口13位置设置，冷凝出风口13相应设置为两个，两个冷凝风机8沿车体长度方向并排安装，两个冷凝器7分设在两个冷凝风机8的两侧，两台压缩机9安装在 一侧的冷凝器7与壳体2对应的侧壁之间的空间内。
如图2所示，图中箭头所指方向为空气流动方向，在空调机组运行时，在两个冷凝风机8的作用下，从设备舱1两侧裙板14的进风口15处进风，经过空调机组两侧侧壁上的冷凝进风口12进入室外侧2内，分别与两个冷凝器7内的高温冷媒进行热交换，换热后的温度较高的空气再从壳体2底壁上的冷凝出风口13排至车外。
本实施例中，将冷凝器7由现有技术中的一个增加为两个，将冷凝风机8由安装在室外侧4的侧面变更到安装在室外侧4的底面，而且由两个侧面同时进风，空调冷凝进风面积较现有技术增加了1倍，从而大幅增加了空调冷凝风量，提升了空调高温时的制冷效果，在高温环境中长时间运营时乘坐的舒适性得到较大提高。
实施例二：
与实施例一不同之处在于，如图3和图4所示，图中箭头所指方向为空气流动方向。本实施例中，壳体2在车体宽度方向上延长，壳体2的两侧侧壁紧靠两侧裙板14的进风口15处设置，壳体2在车体宽度方向上的长度大于在车体长度方向上的长度，即加长了在车宽方向上的长度，缩短了在车长方向上的长度。由于壳体2两侧壁上的冷凝进风口12紧靠裙板14的进风口15，使得从进风口15进入的温度较低的空气绝大部分进入空调机组的壳体2内，参与冷凝器7的热交换，提高了空调机组的换热效率。
本实施例中，由于壳体1在车宽方向上的长度加长，两台压缩机9分别安装于两侧的冷凝器7与相应的壳体2侧壁之间的空间内，两个冷凝风机8沿车体宽度方向并排设置在两个冷凝器7之间，两个冷凝器7在垂向上和水平方向上向车体中心线方向倾斜放置，进一步增加了冷凝器7的换热面积。室内侧3内的蒸发器5也可以相应加长，进而可以增加蒸发换热面积，蒸发风机6可以采用两个，进一步加大的室内通风量。冷凝器面积及蒸发器面积的增加、室内和室外通风量的增加都大幅提高了空调机组的制冷能力，满足空调在高温制冷季节的要求，保证乘客在高温运行环境下乘坐的舒适性。
本实施例由于加长了空调机组在车宽方向上的长度，并与两侧裙板14配合，使空调机组在车长方向变短，改变了现有技术中空调机组的结构和 安装方式，空调机组的两侧不再需要留有较大的供空气流动的空间，而且让出了在车体长度方向上的空间，大幅节省了车下空间。
实施例三：
与实施例二不同之处在于，壳体2的两侧侧壁为敞开口结构，整个侧壁均作为冷凝进风口12，壳体2两侧的侧壁与对应的裙板14之间分别通过连接板(图中未示出)连接，连接板围成进风风道，将冷凝进风口12与裙板14的进风口15连通，将冷凝进风口12与裙板14的进风口15之间隔出一个独立的空间，使得从进风口15进入的温度较低的空气全部进入空调机组的壳体2内，参与冷凝器7的热交换，进一步提高调机组的换热效率。
如上所述，结合附图所给出的方案内容，可以衍生出类似的技术方案。但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
