耦合蓄热闭式循环空气层太阳能供暖建筑热性能研究

Study on Thermal Performance of House with Closed Loop Solar Air Heating Coupled TCM

为了研究均匀辐射墙室内环境调控特性,本研究通过搭建采用空气套构造及墙体内置蓄热材料的闭式循环太阳能供暖实验房和普通构造的对比房,进行了冬季热性能运行实验研究。研究结果表明,采用耦合蓄热闭式循环空气层太阳能供暖系统,即便对于轻质结构供暖房间,也仍然获得了良好的均匀辐射供暖环境;TCM蓄热材料控温效果明显,在相同的室外温度的条件下,使夜间实验房室内空气温度比对比房最大高10℃。另外,对透光围护结构实施夜间保温对抑制昼夜室温波动效果明显。

In order to study indoor environmental control characteristics of the uniform radiation wall, run thermal performance in winter were studied experimentally by using solar air heating test room closed loop with TCM and the reference room. The results show that the use of solar heating systems with closed-cycle air layer coupling temperature control material, even for lightweight construction heating space, still get a good uniform radiant heating environment; temperature control effect of TCM is obvious, under in the same outdoor temperature conditions, indoor air temperature of the test room at night is maximum 10 ℃ higher than the reference room. In addition, the implementation of the transparent envelope insulation at night is obvious for shifting diurnal temperature fluctuation.
