摘要
该文考察了日光温室各部件的湿热平衡，建立、求解并验证数学模型，证明了模型的准确性。分析表明，室内气温主要受室外太阳辐射的影响，而室外气温只具有次要的作用；温室后墙对保证温室热环境具有重要作用，而且其夜间的作用大于白天；随着保温性能的提高，温室的热环境得到稳定改善，特别是当使用透光保温合一型材料时，温室的热环境得到更大的改善。
The thermal environment inside solar plastic greenhouses with one slope is very important and complex. Considering almost all factors that are evident, a thoretical model was set up to discribe the thermal environment, and was verified through experiments. The simulation results showed that the air temperature inside is mainly affected by the outside solar radiation, and the air temperature outside has only a secondary effect. The back wall of greenhouse plays an important role in maintaining the inner thermal condition, which is steadily improved with the improvement of greenhouse thermal insulation and especially with the use of transmitting insulating material.
