| Abstract: | In order to analyze the internal heat environment of solar greenhouse,the heat transfer theories were used to research the heat convection and radiation transfer in greenhouse at night.The greenhouse internal heat equilibrium model was established.This model could be used to calculate the amount of heat needed in winter greenhouses and to evaluate actual application effect of heating system.The study showed the temperature computed was close to the actual degree measured,which meant the equilibrium model could fit the real.The model also displayed the direction and distribution of the heat flux in the greenhouse,and confirmed the role of the palisade structure on greenhouse heat preservation. |
| Keywords: | greenhouse heat equilibrium model heat flow heat input |
