主动式围护结构是传统围护结构的一种改进和强化形式，受到了广泛的关注.提出了一种新型的、有应用前景的主动式建筑光伏热电一体化墙体系统，该系统利用光伏电池将太阳能转化为电能，直接为热电辐射板供电。这种主动系统对周围热环境具有高度的自适应性，可以大规模地减少热增益。建立了动态系统模型，并通过实验数据进行了验证。将光伏板电热模型、风道传热模型和温差辐射板模型耦合起来，建立了BIPVTE墙体系统的热行为分析模型。采用Lambert W函数对光伏板的电学模型进行求解，得到显式表达式;采用状态空间法对光伏板、风道和隔热板的热学模型方程进行矩阵求解;在前人研究的基础上推导出热电辐射板的解析模型。通过模型验证，以传统墙体为参考，对BIPVTE墙体系统的热工性能进行了评价。模拟结果表明，当室内空气温度为24 °C，保温层厚度和导热系数分别为0.04 m和0.05 W/m K时，典型日模拟中BIPVTE墙体比传统墙体可减少约70%的日得热量。
Active building envelope is an evolved and enhanced version of traditional envelope which received extensive attention. This paper presented a novel and promising active building integrated photovoltaic thermoelectric (BIPVTE) wall system that can use the electric power converted from solar energy by PV cells directly serves for the operation of thermoelectric radiant panel. This active system is highly self-adaptive to ambient thermal environment and can reduce heat gain by considerable scale. A dynamic-state systematic model was established and validated through experiment data. Three analytic sub-models related to the electric and thermal model of PV panel, heat transfer in air duct and model of thermoelectric radiant panel were coupled to describe the thermal behavior of BIPVTE wall system. The electric model of PV panel was solved by Lambert W function to deliver an explicit expression; the thermal model equations of PV panel, air duct and insulation board were solved in a matrix form by adopting state-space method; the analytic model of thermoelectric radiant panel was derived from previous study. After model validation, the traditional wall was taken as the reference to evaluate thermal performance of BIPVTE wall system. The simulation results showed that when indoor air temperature is 24 °C, the thickness and thermal conductivity of insulation is 0.04 m and 0.05 W/m K, BIPVTE wall can reduce about 70% daily heat gain compared with traditional wall in typical day simulation.
