Description

一种整合供冷、通风、照明的天花板系统 技术领域
本发明涉及天花板系统，尤其涉及一种整合供冷、通风、照明的天花板系统。
背景技术
天花板系统，是室内的重要部分之一。天花板在整个居室装饰中占有相当重要的地位，目前在建筑天花领域，天花板常采用铝扣板、石膏板等装饰材料，此种天花系统仅具有装饰功能，因此，在天花板施工完毕后还需再安装照明用的灯具，既增加了施工的繁琐性，又使得装饰空间不够简洁，另外灯具分散排布，照明均匀度不高，使得灯下作业的人员容易产生视觉疲劳。
而室内供冷管线复杂、占地面积大、建筑必需一定通风量，将供冷、照明、通风三者与天花板结合模块化生产、使用十分具有意义。
发明概述
技术问题
本发明要解决的技术问题是：如何通过弧面反光片的倾斜方向来调节风量大小，以及如何通过弧面反光片实现辐射换热和对流换热的技术问题。
问题的解决方案
技术解决方案
本发明的目的在于克服上述现有技术的缺点和不足，提供一种结构简单，可模块化自由拼装的整合供冷、通风、照明的天花板系统。
本发明通过下述技术方案实现：
一种整合供冷、通风、照明的天花板系统，包括由隔板3拼接构成的通风道2，通风道2的下侧为出风侧22；通风道2的内顶部盘布有供冷管1；
通风道2的出风侧22阵列安装有一排呈C形的弧面反光片4；各弧面反光片4均按照相同方向，头尾相互间隔呈一字排布倾斜安装在通风道2的结构框架上，其倾斜方向与通风道2的气流流动方向相同或者相反；
在弧面反光片4下方出风侧22的结构框架上安装有照明光源5。
当弧面反光片4的倾斜方向与气流流动方向一致时，为顺风排列方式；当弧面反光片4倾斜方向与气流流动方向相反时，为逆风排列方式。
顺风排列方式出风侧22的出风量＜逆风排列方式的出风量。
弧面反光片4通过转轴与通风道2的结构框架转动连接，所述转轴的轴线垂直于气流流动方向。
所述供冷管1内部流动的工质为制冷机；供冷管1的两端端口连接外部制冷系统。
所述照明光源5为LED光源。
发明的有益效果
有益效果
本发明相对于现有技术，具有如下的优点及效果：
本发明通过整合供冷、通风及照明的天花系统，其供冷主要通过以下两种方式进行实施：一是通过对流换热的方式，即供冷管通过对流换热将温度传入通风道，通风道出风侧的冷空气与人体进行对流换热；二是通过辐射换热的方式，供冷管通过辐射换热将温度传入弧面反光片，即弧面反光片又与人体直接进行辐射换热。通过两种换热方式满足人体的室内热舒适。
当气流的流动方向与弧面反光片的倾斜方向一致时，弧面反光片相当于顺风排列或者称之为背风排列；采用这种排列方式，由于弧面反光片的弧背顺着来风方向，此时进入该段出风侧的气流较小，大部分气流由该段通风道进入下一个与其对接的通风道内。
当气流的流动方向与弧面反光片的倾斜方向相反时或者称之为迎风排列；采用这种排列方式，由于弧面反光片的弧底顺着来风方向，此时进入该段出风侧的气流大于背风排列方式。
本发明通风道可接入风机，也可增加分支管道再接入风机。这种结构可使通风道内空气气流的流速加大，更有效地与供冷管进行对流换热，降低通风道中冷空气的温度，更有效地对室内进行降温。
本发明通风道通过若干块隔板拼装组织而成。采用这种结构，可控制冷空气在通风道中的流通方向及其出口位置自由拼接、组合。使得本发明的应用场所及 方式更加灵活多样。
本发明通风道可模块化对接、组装，各模块及供冷管之间可相互衔接，供冷管连接之后的整体再通入制冷系统。通风道实现模块化后可整体通风。
本发明LED光源安置于弧面反光片4(反光罩)的下方。采用这种结构后，LED光源照射到反光罩上，通过其反射及散射，将光线导入室内，使得室内的照度更加的均匀，且由于LED光源体积很小可隐于通风道的结构框架上，使得天花系统更加的美观。
对附图的简要说明

图2为弧面反光片顺风排列方式示意图。
图3为弧面反光片逆风排列方式示意图。
发明实施例
本发明的实施方式
下面结合具体实施例对本发明作进一步具体详细描述。
实施例
如图1-3所示。本发明公开了一种整合供冷、通风、照明的天花板系统，包括由隔板3拼接构成的通风道2，通风道2的下侧为出风侧22；通风道2的内顶部盘布有供冷管1；
通风道2的出风侧22阵列安装有一排呈C形的弧面反光片4；各弧面反光片4均按照相同方向，头尾相互间隔呈一字排布倾斜安装在通风道2的结构框架上，其倾斜方向与通风道2的气流流动方向相同或者相反；
在弧面反光片4下方出风侧22的结构框架上安装有照明光源5。
当弧面反光片4的倾斜方向与气流流动方向一致时，为顺风排列方式；当弧面反光片4倾斜方向与气流流动方向相反时，为逆风排列方式。
顺风排列方式出风侧22的出风量＜逆风排列方式的出风量。
当气流的流动方向与弧面反光片的倾斜方向一致时，弧面反光片相当于顺风排列，此时出风侧的出风量最小。
当气流的流动方向与弧面反光片的倾斜方向相反时，弧面反光片相当于逆风排列，此时出风侧的出风量最大。
所述供冷管1内部流动的工质为制冷机；供冷管1的两端端口连接外部制冷系统。
所述照明光源5为LED光源。
本发明弧面反光片4通过转轴与通风道2的结构框架转动连接，所述转轴的轴线垂直于气流流动方向；通过弧面反光片4可转动式活动连接方式，可实现出风侧22出风量大小可调。通过转动，还可改变弧面反光片4的倾斜角度和方向，使其处于顺风或者逆风状态。
本发明通过整合供冷、通风及照明的天花系统，其供冷主要通过以下两种方式进行实施：一是通过对流换热的方式，即供冷管通过对流换热将温度传入通风道，通风道出风侧的冷空气与人体进行对流换热；二是通过辐射换热的方式，供冷管通过辐射换热将温度传入弧面反光片，即弧面反光片又与人体直接进行辐射换热。通过两种换热方式满足人体的室内热舒适。
本发明供冷管1作为制冷系统的蒸发器部件，通风道2通过风机增加风速，通过对流换热，供冷管1的冷量可有效传入通风道2内，出风侧22的方向可通过通风组织隔板的调整安置进行选择；
当弧面反光片4顺风排列时，出风侧22的出风量减小，可有效解决该段通风道内冷风泄露问题。本发明天花系统可模块化通过室内实际空间需要相互进行拼接安装，以达到最佳供冷、通风、照明效果。
如上所述，便可较好地实现本发明。
本发明的实施方式并不受上述实施例的限制，其他任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化，均应为等效的置换方式，都包含在本发明的保护范围之内。
