- Abstract:
- This project aimed to build a dynamic model for the thermal environment of Gobi solar greenhouse in south Xinjiang Province，which promoted analyzing and evaluating heat isolation performance of such kind of solar greenhouse and offered important basis for optimizing greenhouse design and construction.Based on the theories of engineering thermophysics and greenhouse environmental engineering，a dynamic model for the thermal environment in Gobi solar greenhouse was built.The continuous air temperature，soil temperature and wall temperature in Gobi stone made solar greenhouses in Ke District，South Xinjiang was tested to analyze and verify the model.Five days’ measured data had same variation with the simulated ones with correlation coefficient over 0.9，and the average relative errors between them were about 1.2-2.3℃.The results showed that this model could accurately predict the temperature transformation rule in Gobi stone solar greenhouse and could be an important reference for heat environment and isolation performance evaluation of such kind of greenhouse.
