中文摘要:

      利用太阳能集热器制得低温热水作为地板辐射采暖系统的热源,是一种清洁、节能、舒适的采暖方式。本文在南京地区搭建了太阳能地板辐射采暖系统实验台,系统运行策略为白天集热,夜晚采暖,通过实验得到了集热器集热效率、地板进出水温度、室内不同朝向围护结构温度、不同高度的空气温度等参数,最后对系统的性能进行了概括和总结。

英文摘要:

      Using solar collector to produce low temperature hot water as the heat source of floor radiant heating system is a kind of clean, energy saving and comfortable heating mode. In this paper, the experimental platform of solar radiant floor heating system is set up in Nanjing, and the operating strategy of the system is solar collecting during the daytime, and heating during the night. Thermal efficiency of the collector, inlet and outlet water temperature of the floor, temperature of the building envelopes of different orientation and air temperature of different height were obtained. Finally, the performance of the system is summarized.
