摘要： A dynamic simulation method of thermal environment was presented to evaluate the thermal performance of solar greenhouse. Solar greenhouse was firstly simplified into several components according to characteristics of its structure and materials, and then each component was divided into several temperature elements. For each element, heat balance equation was respectively built and integrated into a lumped model which was used to describe the thermal system of solar greenhouse. Consequently, a dynamic simulation based on state-space method was developed to calculate indoor temperature variations under the ambient conditions and structures of solar greenhouse. Experimental results show the presented method can simulate the long-term changes of indoor temperature, and are beneficial to evaluate and predict the thermal performance of solar greenhouses.
