摘要
提出了温室气候的动态模型,在模型中考虑到了温室内三层土壤、作物层、室内空气和覆盖物之间的传导、对流、太阳辐射和热辐射以及潜热交换,在此基础上,研究了比利时典型天气条件下温室内的温度和热流通量的变化,认为室内气温主要取决于室外气温、太阳辐射和热辐射,所以,对玻璃温室的对流传热损失和塑料大棚的热辐射损失必须引起足够重视。
A greenhouse climate dynamic model was presented which took into account conductive,convective,solar and thermal radiation as well as latent heat exchanges between 3 soil layers, vegetation, interior air and cover. The temperatures and heat fluxes in the greenhouses had been studied for a typical climate day of Belgium. The results showed that the interior air temperature was mainly dependent on the exterior air temperature .solar and thermal radiation. Attention should be paid to the convective heat loss for the glass greenhouses and thermal radiative heat loss for the plastics film greenhouses. Validation has shown the high degree of reliability of the model.
