【摘要】：随着国民经济的可持续发展，人民生活水平的不断提高，资源枯竭和环境污染逐渐成为困扰人类的两个长期的、严重的问题。建筑能耗占总能耗的30％，因而，节能建筑对我国可持续发展至关重要，利用太阳能为人类服务的太阳能建筑以它得天独厚的条件应用而生。 本文以西安市mP灞农村山区的某实体墙式集热蓄热墙被动式太阳房为研究对象。根据文献资料，对研究模型的围护结构和集热蓄热墙的主要部件的参数和结构进行了优化设计选择，为研究对象的设计提供参考依据。应用理论计算方法对所研究的太阳房的室内热工（供暖率SHF、所需辅助热量Qa mx、节能率ESF）进行了详细的计算，并预测了太阳房在采暖期室内各月的平均温度，为新农村太阳房的室内热工设计提供了理论依据。最后，通过Fluent软件对太阳房模型的温度场、速度场进行了数值模拟，模拟计算出太阳房模型的室内平均温度，并与理论计算结果加以分析比较，验证了理论计算结果的正确性。 通过本文的研究，，为被动式太阳房在西安地区的可行性奠定了理论基础，对普通建筑的节能也具有重要的参考价值。
[Abstract]:With the sustainable development of national economy and the continuous improvement of people's living standards, resource depletion and environmental pollution have gradually become two long-term and serious problems that haunt mankind. Building energy consumption accounts for 30% of the total energy consumption. Therefore, energy saving building is very important for sustainable development of our country. Solar energy building which uses solar energy to serve human beings is born from its unique conditions. In this paper, the passive solar house with wall type heat storage wall in the rural mountainous area of mP Ba in Xi'an is taken as the research object. According to the literature data, the parameters and structure of the main parts of the research model and the main parts of the heat storage wall are optimized and selected, which provides a reference for the design of the research object. The indoor thermal engineering (Qa mx, energy saving rate (ESF) of auxiliary heat needed by heating rate SHF,) is calculated in detail by using theoretical calculation method, and the average temperature of solar room in each month during heating period is predicted. It provides a theoretical basis for the indoor thermal design of the solar house in the new countryside. Finally, the temperature field and velocity field of the solar room model are simulated by Fluent software, and the indoor average temperature of the solar room model is simulated and calculated. The results are compared with the theoretical results, and the correctness of the theoretical calculation results is verified. Through the research of this paper, it lays a theoretical foundation for the feasibility of passive solar house in Xi'an area, and also has important reference value for the energy saving of ordinary buildings.
