利用供热水管进行夜间蓄热对供暖成本的影响

The Influence of Heat Storage at Night Time on Heating Cost by Heating Pipe

在既有的冷热源中心,有限的空间是应用夜间蓄热技术的主要阻碍。本文提出通过对水系统进行局部改造,将热水储存在水管内部,并研究分析了水管管径、保温性能和周围环境参数对夜间蓄热方法的经济性的影响效果。结果表明,水管管径越大,越适合作为夜间蓄热空间。夜间蓄热水管的管径较大时,无需增加管道保温性能,但管径较小时,应该加强管道保温,同时应尽量减少管道放置空间的通风换气量,以减小夜间蓄热的热损失。

In the existing centre of the cold and heat sources, limited space is a major problem to apply the thermal energy storage during the night, for which this paper put forward a plan that storage the hot water in the pipe by partly reform the water system and analyzes the economic effects to he heat-storage method at night of the pipe diameter, heat-insulating property and surroundings parameters. The results shows that with the increase of pipe diameter, it is more suitable to consider the water pipe as heat-storage space. There is unnecessary to enhanced pipe insulation performance when the diameter of the heat storage pipe is large, while on the contrary, it is sure to increase the pipe insulation and decrease the ventilation quantity of the space where the pipes are at the meantime so as to reduce the heat loss of the night heat storage.
