According to the solar building characteristics,we established simulation analysis software suitable for solar building indoor thermal performance; analysed the impact of solar energy applied in the building on indoor temperature and load; and provided reference data for the design of the solar building heating and cooling systems. Based on VB visual programming language, using the method of " ADO data control + SQL statement" and through the ODBC connected with database interface, established the national climate database; databases of different wall types, window types, and radiation floor materials in different regions, etc. The program refers to the outer - wall temperature heat transfer calculation method to calculate the indoor cold (heat) load, and the parametric thought that uses APDL( ANSYS parametric design language) to realize the visualization parametric modeling of floor for heat transfer calculation. Then we got the results: for example, on 1 st January in Shenyang, with only solar energy floor heating in practical building conditions, the standard indoor design temperature, 18℃ ,can not be reached;and the amount of auxiliary heat for the water supply temperature controlled at 40℃ is greater than the amount for that uncontrolled when we use solar energy for heating only. This software could calculate thermal parameters of rooms in different locations.different time and different rooms, so it could be used broadly. It also has opened databases and outputs in graphs and tables, so it is easily understood.%目的 针对太阳能建筑自身的特点,编制适用于太阳能建筑的室内热工性能模拟分析软件,分析太阳能在建筑中应用时对室内温度和负荷的影响,为太阳能建筑冷热源系统的设计提供参考.方法 基于Visual Basic可视化程序设计语言,运用“ADO数据控制项+SQL语句”并通过ODBC同数据库接口相连接的方法建立全国气候数据库、适用于不同区域的墙型窗型和辐射地板材料等数据库；引用参数化思想运用APDL(ANSYS参数化设计语言)实现地板可视化的参数化建模进行地板的传热计算.结果 以沈阳地区1月1日气象参数为例,仅利用太阳能地面辐射供暖不能达到室内设计温度18℃的要求；采用太阳能地板辐射采暖时,控制供水温度为40℃时的辅助热源量大于非控温运行下的辅助热源量.结论 该软件可以对不同地点、不同时间和不同的房型的建筑热工参数进行计算,具有广泛性；采用数据库的形式,具有开放性；结果有可靠性且以图表的形式输出,具有直观性.
