Study On The Application Of Solar Energy In Rural Residentials In Sichuan And Chongqing

Since the outbreak of the world energy crisis in 1970 s,the energy problem has attracted worldwide attention.At present,straw,firewood and other biomass is still the living energy for two hundred million of China's rural residents,resulting in the destruction of vegetation,ecological deterioration.China's fossil energy shortage,environmental pollution is serious,there is an urgent need to use renewable energy sources.The promulgation of the People's Republic of China renewable energy law has accelerated the development of solar energy applications in China.Moreover,the rural areas have the advantages of solar energy application in the ecological environment,planning layout and architectural forms,providing the prerequisite for the promotion of solar energy in rural areas.In addition,the solar water heating system and the solar photovoltaic system can achieve self-sufficiency,and can solve the energy shortage and irrational structure in the rural areas.Passive solar energy technology can achieve solar heating and solar cooling,and can effectively improve the indoor thermal comfort of rural residential.Therefore,strengthening the study of solar energy applications in rural residential buildings has become an urgent matter for architects.The topic of this thesis is derived from the 12 th Five-Year National Science and technology support program(Project No.2013BAJ11B01),"key technologies and demonstrations for intensive planning and construction of mountain villages".Under the background of town and village construction in urban and rural areas,this paper studies the planning and construction of intensive development of villages and towns in Sichuan and Chongqing urban and rural areas as a whole from the two ways of "technology integration" and "regional demonstration".By participating in the research,found two problems: Sichuan Chongqing region,and unlike the traditional concept that cannot use solar energy,not only can be used,but also achieved good results;due to the factors unique to this area,causing some difficulties of solar energy application.Based on these two findings,this paper attempts to study and analyze the feasibility of solar energy applications in Sichuan and Chongqing regions,the reasons for the solar energy promotion and the solar energy application mode applicable to rural residential buildings in this areas.Based on the rural area of Sichuan and Chongqing,to more accurately and more intuitively and provide a theoretical basis for the application of solar energy,trying to summarize for the rural residential solar energy application in Sichuan and Chongqing area to adapt to the specific form of principle,improvement strategy and architects can directly use solar energy should be used,hoping to promote the promotion of solar energy in this areas.Through access to a large number of domestic and foreign solar applications to literature,literature analysis,field research,questionnaire investigation,research in accordance with the technical route of "putting forward the question,analyzing the question and solving the problem".This paper first conducts the research of Sichuan and Chongqing area and geographical conditions,climatic characteristics,solar energy survey,followed by the planning and architectural design of rural residential area of Sichuan and Chongqing energy use situation and thermal comfort requirements,the application status of solar energy research,found in the area to promote the cause of solar energy,which is to be the primary factor,secondly.The form does not meet the demand,resulting in favorable conditions for good solar energy;no use of the receiving surface,leading to the use of solar energy in adverse conditions.Based on this,this paper first demonstrated the feasibility of the rural residential solar energy application area of Sichuan and Chongqing,then put forward the principle of rural residential solar energy application in this region,which is adapt to the whole focus on integration,systematic design,adapt to the difference,appropriate to meet the technical requirements,to adapt to the difference in different direction.In addition,after the full use of domestic and international experience,put forward the feasible improvement strategies,namely the overall design,including space integration design,appearance design system of energy saving measures;route diversification,application mode,low technology include high technology route;toward the difference.Including the optimization under favourable conditions,measures to deal with the application of solar energy solar energy application measures under adverse conditions.Then,taking the adaptation principle as the starting point and making full use of the improvement strategy,the paper puts forward the practical form of solar energy application in the rural residential area.Finally,using the theory put forward by the research to analyze the examples of rural housing in this area,provide more detailed and specific reference for architects,and provide proof for the views of the paper.
