西安新農(nóng)村被動式太陽房熱工設(shè)計
[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.
