分析了控温材料(TCM)在不同采暖方式及不同布置形式下对室内温度的影响;利用吸热系数B分析了TCM对房屋热稳定的影响;比较了各布置工况的平均辐射温度及布置前后的不均匀辐射变化;研究了对室内热舒适性的影响。研究结果显示:在太阳能采暖系统停止工作的夜间,TCM可以抑制室温的波动;太阳能空气采暖系统白天工作时,增大北墙和顶棚的TCM布置量,夜间非采暖阶段增大东西墙的TCM布置量,更有利于提高房屋的热稳定性;东西北墙和顶棚布置TCM,比无TCM布置时的辐射不均匀度降低了20%左右。
Firstly,an effect of thermal control material (TCM) with different installations and different heating systems on the indoor temperature was analyzed and tested. Secondly, a heat absorption coefficient B was used to analyze the effect of TCM installations on building thermal stability; Finally, the mean radiant temperature in different conditions and asymmetric radiation of the house with or without TCM installations were compared to study the TCM's effect on thermal comfort. The results show that TCM can restrain the temperature fluctuation during non-heating period, it is more conducive to thermal stability when increasing the installing amount on the north wall and ceiling during heating period and increasing the installing amount on east and west wall during non-heating period. Asymmetric radiation with TCM installed on the three walls and ceiling is about 20% lower than that without TCM installation.
