Description
技术领域
本发明涉及一种无动力降温蓄热墙体系统,属于建筑物节能暖通技术领域。
背景技术
现有的建筑物供暖、降温,一般采用空调系统进行,整体能耗比较大,如何提供一种节能、高效的墙体系统,实现墙体的蓄冷和供暖,是本领域亟待解决的技术问题。
发明内容
本发明的目的是提供一种无动力降温蓄热墙体系统,在户外高于设定温度时,利用空调冷凝水穿过墙体内预埋的毛细管对墙体进行降温;在户外高于设定温度时,将通过太阳能集热管加热后的水体与所述毛细管连通,实现热传递,进而实现墙体蓄热。
本发明采取以下技术方案:
一种无动力降温蓄热墙体系统,建筑物外墙内纵向预埋设置多组毛细管1;每个楼层均上下依次设置空调冷凝水泄水口12和种植槽6和;所述空调冷凝水泄水口12设在位于室外的落水管10内,并通过第二温控阀13 与下一层墙体的毛细管1上端连通;所述种植槽6外壁上设有太阳能集热管8,本层墙体内的所述毛细管1底部伸入种植槽6,并通过第三温控阀14 选择与所述太阳能集热管8连通或与种植槽6连通;所述太阳能集热管8 外接水源处设有第一温控阀7。

优选的,所述毛细管1的内径为3-5mm。
优选的,所述毛细管1在建筑物外墙呈倾斜S形连续布置。
进一步的,滤水槽5底部具有一种植槽排水口9,所述植槽排水口9的位置对准所述落水管10。
一种无动力降温蓄热墙体的工作方法,空调冷凝水温度在设定温度A 以上时,第一温控阀7关闭,第二温控阀13开启,第三温控阀14关闭,建筑上层的空调冷凝水经过第二温控阀13,进入毛细管1内,墙体内毛细管和外保温层一起阻止室外的热量向室内传递;同时,毛细管内的冷凝水通过重力向下流动的过程中,吸收室内热量,降低室内热负荷;毛细管内的冷凝水经过一层楼的热交换过程,排向本层的种植槽内,继续灌溉垂直绿化;当种植槽的水过多时,通过滤水槽,经过种植箱排水口,从墙体的落水管排出;当空调产生的冷凝水过多时,不能进入墙体毛细管的水通过冷凝水泄水口12直接向落水管排出;空调冷凝水温度在设定温度A以下时,第二温控阀13关闭、第三温控阀14开启、第一温控阀7开启,毛细管内的冷凝水不再向外排出;同时,太阳能集热管8启动工作,通过第一温控阀7流进太阳能集热管中的水被太阳能加热,加热后的热水,又通过第三温控阀14与墙内的毛细管1连通,进而与毛细管中的冷水进行热交换,逐渐使整层的毛细管的水都被加热;同时,墙体的外保温层阻隔室外的冷空气进入墙体,使毛细管热水单向与室内发生热交换。
本发明的有益效果在于:
1)提供一种无动力降温蓄热墙体系统,在户外高于设定温度时,利用空调冷凝水穿过墙体内预埋的毛细管对墙体进行降温;在户外高于设定温度时,将通过太阳能集热管加热后的水体与所述毛细管连通,实现热传递,进而实现墙体蓄热;同时,在温度较高的季节,可以利用空调冷凝水对户外的种植槽进行浇灌,实现节能减排。
2)无额外设备和能耗就可以利用空调冷凝水通过重力作用,在墙体中的无动力流动,实现对室内进行蓄热或降温,实现与建筑一体化设计和施工,有利于减少建筑能耗;并具有均匀提供室内热辐射环境的功能,大大提高了系统的使用价值,满足室内人员热舒适需求并节约能耗。

具体实施方式
下面结合附图和具体实施例对本发明进一步说明。
参见图1-2,一种无动力降温蓄热墙体系统,建筑物外墙内纵向预埋设置多组毛细管1;每个楼层均上下依次设置空调冷凝水泄水口12和种植槽 6;所述空调冷凝水泄水口12与室外的落水管10相连,并通过第二温控阀13与下一层墙体的毛细管1上端连通;所述种植槽6外壁上设有太阳能集热管8,本层墙体内的所述毛细管1底部伸入种植槽6,并通过第三温控阀 14选择与所述太阳能集热管8连通或与种植槽6连通;所述太阳能集热管 8外接水源处设有第一温控阀7。
在此实施例中,所述种植槽6内底部设有一滤水槽5,所述滤水槽5下部与所述落水管10连通。
在此实施例中,建筑物外墙上与种植槽平台和空调室外机平台一体化设置,所述种空调室外机平台设于下层楼层外墙外部,所述植槽平台设于本层楼层外墙外部。
在此实施例中,所述太阳能集热管8的管路埋入所述种植槽6之中。
在此实施例中,同一种植槽6与多组并列的所述毛细管1相对应。图中未进行展示。
在此实施例中,所述毛细管1的内径为3-5mm。
在此实施例中,所述毛细管1在建筑物外墙呈倾斜S形连续布置。
在此实施例中,滤水槽5底部具有一种植槽排水口9,所述植槽排水口 9的位置对准所述落水管10。
降温:
建筑上层的空调冷凝水向外排出,经过冷凝水泄水口和温控阀(冷凝水温度在15度以上时,第一温控阀7关闭,第二温控阀13开启,第三温控阀14关闭,),冷凝水进入外保温墙体(保温层外置)系统的毛细管内,墙体内毛细管和外保温层一起阻止室外的热量向室内传递;同时,毛细管内的冷凝水通过重力向下流动的过程中,可以吸收室内热量,降低室内热负荷。毛细管内的冷凝水经过一层楼的热交换过程,温度基本和室内一致,冷凝水排向本层的种植槽内,继续灌溉垂直绿化。当种植槽的水过多时,通过滤水槽,经过种植箱排水口,从墙体的落水管排出,防止种植槽内灌溉水过多,影响植物生长。冷凝水泄水口直接与落水管连接,当空调运行较高,产生的冷凝水过多时,不能进入墙体毛细管的水可以通过冷凝水泄水口直接向落水管排出。
蓄热:
当室外温度低于15度时,第二温控阀13关闭、第三温控阀14开启、第一温控阀7开启,管内的冷凝水不再向外排出。同时,太阳能集热管启动工作,流进太阳能集热管中的水被太阳能加热,加热后的热水,又流向墙内毛细管内,与毛细管中的冷水进行热交换,热水逐渐向上,逐渐整层的毛细管的水都被加热,与室内发生热交换。同时,墙体的外保温层阻隔室外的冷空气进入墙体,使毛细管热水单向与室内发生热交换,有利于减少毛细管水的热损失,提升室内热交换效果。
寒冷的天气,种植槽的遮阳植物已经枯萎,不需要额外浇灌,也不需要额外冷凝水的供给。
优点:无额外设备和能耗就可以利用空调冷凝水在墙体中的无动力流动,实现对室内进行蓄热或降温,实现与建筑一体化设计和施工,有利于减少建筑能耗;并具有均匀提供室内热辐射环境的功能,大大提高了系统的使用价值,满足室内人员热舒适需求并节约能耗。
以上是本发明的优选实施例,本领域普通技术人员还可以在此基础上进行各种变换或改进,在不脱离本发明总的构思的前提下,这些变换或改进都应当属于本发明要求保护的范围之内。
