| 英文摘要 | 该文建立了日光温室热环境模拟模型,定量描述了日光温室内的太阳辐射、对流换热、辐射换热、热传导、自然通风和水分相变带来的潜热对日光温室热环境的影响,根据质能平衡和传热学理论,得到一组关于覆盖物、室内空气、温室分层后墙、分层地面土壤、分层后坡和作物热平衡的微分方程组。利用MATLAB的强大计算能力与VB的良好用户界面建立模拟计算软件,可求得温室各组成部分的温度。通过试验验证,该模型能够比较准确预测日光温室环境温度。; The simulation model for thermal environment in Chinese solar greenhouse was established,in which the solar radiation,heat radiation,heat convection,heat conduction,natural ventilation and water phase transformation were described quantitatively.And the impacts on thermal environment were analyzed.According to thermodynamic law of conservation of mass and energy and heat transfer theory,a group of differential equations on thermal balance of cover,thermal balance of indoor air, thermal balance of multi-layers of north wall,thermal balance of multi-layers of soil,thermal balance of multi-layers of north roof and thermal balance of plant were built.The simulation model was developed with MATLAB procedures used to solve differential equations,and good user interface of VB,and the temperatures of different parts could be calculated.It shows that the model can accurately predict the temperature in greenhouse environment from experimental results. |
