Study On Heat Storage Optimization Of Terminal Building Envelope Based On Energy Saving

Terminal is an energy-intensive long-span public building,which has high requirement for indoor environment comfort level, needs a steady temperature. However,the energy conservation design of modern terminals is more focus on heat insulation and heat preservation design of palisade structure, ignoring the impact of heat storage on building energy efficiency.This study will plan terminal building layout reasonablely,combing the thermal effect of terminal under the solar radiation and outdoor environmental factors and heat storage of building materials.This study's purport is regenerative energy saving of terminal energy-intensive architecture, combines with theory analysis of heat transfer and fluid dynamics, establishes the physical and mathematical model of the terminal indoor temperature, uses the FLUENT software to probe 3d simulation of the temperature distribution inside terminal, combines with heat transfer characteristics of the different parts of the palisade structure, discusses the heat storage performance of different building materials of the common structure. Taking Nanjing Lukou Airport T2 Terminal as an example, calculate the its building heat capacity and provide guidance advice for heat storage optimization design of heat storage. Through the material accumulation exothermic experiments, the ability of heat accumulation of the optimized construction materials and construction is got. Find the new type of building energy-saving materials with regenerative potential, optimize structure form and conclude the best heat storage performance of palisade structure combinations. These materials are reasonable arranged to the different parts of palisade structure of the terminal building. Finally, the FLUENT software is used again to verify the influence rule of the building heat storage optimization of terminal indoor temperature distribution.Through the heat storage performance optimization research of terminal building palisade structure, the influence law of terminal indoor temperature field which takes heat storage into account is revealed. The theoretical support is provided for energy intensive public building design material selection and energy saving measures.
