Abstract:
The greenhouse is an important part of the agricultural facilities in China.As the main component of greenhouse，the north wall envelope structure not only affects the internal temperature environment，but also has a direct impact on the production efficiency of greenhouse.Firstly，the nine different types of greenhouse wall in Shandong Province were introduced，through the heat transfer effect of the building enclosure，the effects of heat resistance，heat capacity，coefficient of thermal storage and thermal inertia index of nine kinds of greenhouse wall on greenhouse temperature environment were analyzed.Secondly，ceramsite concrete was selected to form a new type of wall，and then the thermal properties of the wall were analyzed,compared with the thermal properties of nine typical solar greenhouse walls.The results showed that ceramsite concrete had smaller density but higher thermal resistance than clay brick and other common wall materials in greenhouse in the past.In addition，its heat storage capacity was better than clay brick under the same density，and the material could be processed by solid waste，which was green and environmental protection.According to the aspects of heat preservation，heat storage and environmental protection，ceramsite concrete was a kind of material suitable for the back wall of greenhouse.
