1、摘要低温热水地板辐射采暖是一种利用建筑物内部地面进行供暖的系统。它既能高效地使用各种低品位能,达到节能效果;又具有室内温度均匀、卫生条件高、舒适性好等特点。是一种减少建筑能耗提高热舒适性的理想供暖系统。本论文就是在参考了很多资料后,在老师的指导下针对大庆市某住宅楼设计的一个地板采暖系统。同时还对建筑的给排水消防系统做了设计。首先对住宅楼进行采暖热负荷计算, 由于地板辐射采暖室内实感温度高于设计温度,所以计算时采用相应降低室内计算温度的方法,满足节能要求。在管道铺设方面,选择了双回形铺设的方式。这种铺设方式地板表面的均匀,满足了舒适性要求。最后,在各户安装温控阀和热计量表,对各户房间进行温度控制

It not only efficiently makes use of the various low energy to the energy efficiency, but also has the even room temperature 、good sanitation、goo
3、d comfort and so on. So it is a ideal heating system that reduces the consumption of energy and raises the thermal comfort ears. This thesis was done after reading many correlative studies, under the guidance of my teachers. First, it calculates the heat load of the housing building. Perceived room
4、temperature exceeds the designed temperature of floor panel heating, so the floor heating has the differences in indoor thermal comfort from that of other heating modes on the basis of thermal comfort theories. Through a quantitative analysis of overall energy efficiencies, this design adequately re
5、duces the indoor heating temperature of the heat load calculation while keeping the same heating effect. In aspect of the laying tubing, this paper adopts the double spiral of concrete embedded plastic radiant floor heating. The method can achieve a even floor surface temperature. Last, the heat met
