中文摘要	Environmental conditions inside a solar greenhouse vary dynamically throughout the day. The large temperature variations in a solar greenhouse were predicted for climatic conditions in northern China on a winter day. The momentum, mass and energy conservation equations were solved using the finite element technique for the flow and temperature distributions inside the greenhouse. The boundary conditions were based on hourly measured data for the solar insolation and the sky, soil (1 meter below the surface) and the outside air temperatures, plus other parameters describing the external convection and radiation. The temperature differences between the simulated soil surface temperatures and the measured surface temperatures during the night differed by no more than VC, with average differences between the simulated and measured air temperatures in the daytime of about 2 degrees C. The simulation was then used to investigate the influence of the boundary conditions on the greenhouse temperatures.
