摘要
以采用南向壁挂式太阳能空气集热器采暖的实体大实验房为对象,通过实验系统地研究了不同运行工况下混凝土楼板的蓄放热特性对抑制室温波动的影响。同时,在实验的基础上,通过模拟的方法计算分析了基于壁挂式太阳能空气集热器采暖系统作用下不同热质水平及热质的设置位置对室内热环境的影响。研究发现,建筑总热容量越大,室温波动越小,但是当热容量达到一定值后这种影响可忽略。通过正交试验分析得到,围护结构与蓄热楼板热容量的最佳比例是5∶1,蓄热楼板的传热系数越大越好。
The effect of charge/discharge performance of thermal storage slab on shifting indoor temperature swing in difference conditions were experimental investigated by using test room with solar air collector（WSAC） mounted on the south wall. Basing on the experiment results, the effect of design optimization of thermal mass on indoor thermal environment was numerical studied. The results show that the greater building thermal capacity is the less the indoor air temperature swing. However, this effect can be neglected when the capacity were big enough; the best thermal capacity ratio of envelop to thermal storage slab is 5：1 ; the heat transfer coefficient of internal thermal mass is bigger, is better.
