摘要
特朗贝墙体的集热性能对特朗贝墙式被动式太阳能建筑的热性能具有重要影响。本文借助计算程序采用一维热网络模型对特朗贝墙体的集热性能进行了分析计算,计算中考虑了被绝大多数同类研究忽略的空气间层内玻璃盖板侧的自然对流换热,以及玻璃盖板与吸热面的辐射换热。在被动式太阳能建筑中用实测值对被动式太阳房的热性能进行了验证;并基于此计算方法,对特朗贝墙式被动式太阳能建筑的热性能进行了讨论。
Solar collecting performance of Trombe wall has important effect on that of Trombe passive solar house. The analytical calculation of the solar collecting performance of Trombe wall which use one-dimensional thermal network have been presented. The glazing-side natural convection in the air gap and the radiation between the absorptive surface and the glazing, which were neglected in most of researches, are taken into account. In order to verify the accuracy of the solutions, experiments have been done in the passive solar house. Comparing the calculated results with the examined data, the method can be used in analyzing and predicting the solar collecting performance of the Trombe wall.
