At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.

经过两年多的实测和计算，根据传热学、流体力学、统计学等学科的基础理论，对大量数据进行整理归类、分析讨论，主要得到如下结论：(1)冬季，含有特朗贝墙体的被动式太阳房室内热湿环境较舒适性标准偏低，但人体感觉比较舒适，特朗贝墙体形成的热循环通风在调节室内温度和相对湿度方面起到很大的作用；(2)特朗贝墙体空气间层自然对流可以看作是两个等温独立大平板的自然对流换热过程的叠加，通过与大平板自然对流理论类比获得了计算热循环过程中对流换热量的经验公式；(3)特朗贝墙体通风口的启闭可以根据玻璃幕墙内壁面温度、蓄热墙体外壁面温度和空气间层进出口空气温度之间的关系来进行控制，从而有效地阻挡冬季冷循环的发生；(4)夏季，如没有有效的通风降温措施，被动式太阳房内会产生明显的过热。
