Simulation and analysis of the temperature inside the sunlight greenhouse

In order to provide meteorological factors for the typical sunlight greenhouse in Beijing areas, temperature was simulated inside sunlight greenhouse. According to the method of heat balance, taking the sunlight greenhouse crop into account, mathematics model was set up to simulate the temperature inside the greenhouse with crops inside. The whole space of the greenhouse was divided into five parts. Five equations were created and results of the equations were solved using Gauss main element elimination method. The temperature inside each surface in the greenhouse was simulated and the results were analyzed. The simulated results were good and the mean absolute difference was 0.9℃ and the mean relative difference was 5.1 percent. The simulated difference was also analyzed.
