中文摘要：
建筑内部热质体性能对室内热环境起着十分重要的作用。本文通过建立被动式太阳房＂双板＂简化模型,以提高室内热舒适度为目标,从反问题的思路研究建筑内部热质体非线性理想比热容。提出了多尺度十段法来近似描述热质体的非线性比热容特性,计算了北京冬季一月份工况下,不同导热系数的内部热质体非线性理想比热容特性。结果表明：该方法可有效求解建筑内部热质体的非线性理想比热容特性;理想非线性比热容特性近似于δ函数;在一定范围内导热系数增大对热质体优化后室内热舒适度影响不大,比热容集中点略微上移。
英文摘要：
The internal building thermal mass influences the indoor thermal comfort significantly.A simplified two-plate model is built to optimize non-linear specific heat form of the internal thermal mass of a passive solar room to improve the indoor thermal comfort by solving the inverse problem. A multi-scale ten-segment model is presented to approximate the non-linear specific heat form.The ideal non-linear specific heat form of the internal thermal mass for a passive solar room in January in Beijing is obtained with different thermal conductivities.The results show that the proposed method can be used to estimate the ideal non-linear specific heat effectively;the ideal non-linear specific heat of the thermal mass approaches to theδfunction;the optimized thermal comfort degree changes little with the increasing thermal conductivities.
