Research and Development of Software for Thermal Environmental Simulation and Prediction in Solar Greenhouse

运用工程热物理和温室环境工程等理论,构建了日光温室热环境的动态模型,并采用有限差分等数值算法,编制成日光温室热环境模拟预测的软件。结果表明:该软件可以对给定的地理位置、室外气象条件下,采用一定的建筑材料、建筑和构造方案的日光温室,模拟其室内热环境全天的变化情况,同时可对日光温室热环境性能进行预测和评价,比较和确定优化的设计方案。

Based on the theories of engineering thermophysics and greenhouse environmental engineering,the author built a dynamic model for the thermal environment in solar greenhouse,and used numerical algorithms like method of finite difference to develop a software to simulate and predict the thermal environment in solar greenhouse.If geographical position,meteorological conditions outside,construction materials and structure plan of the greenhouse are given,the software can simulate the entire day＇s changing situation of the thermal environment inside.It can also predict and estimate thermal environment function of solar greenhouse,and then help designers to choose an optimum design plan for solar greenhouse.
