Application Research On Appropriate Model Of Solar Energy Utilization In Central Shaanxi Rural Residence

Along with rural economy development,rural housing construction has entered a period of rapid development.But the present situation is:Villagers' building energy saving consciousness is frail,and they are low to the environment comfortable demand, there aren't standard specifications of architectural design and building energy saving to take the instruction.They are accustomed to blind imitation or put more attention on building cost reduction.It causes rural housing construction to neglect climatic factors, and rural housing more and more doesn't have the local characteristics;In the aspect of building thermal,residential environment performance's thermal performance is bad, there are typical malignant characteristics which are high consumption,high emission and low comfort.So,according to rural native characteristics to solve the sustainable development problem of residential area is the goal which architectural field ponders continuously and struggle diligently in recent years.This paper is the subproject of" Research on energy-saving residential building about solar energy utilization model and construction in central Shaanxi rural residence",which is Shaanxi province education department special scientific research project.Takes the research object by rural housing in the zone of central Shaanxi plain,through a large number of field investigations and physical environment tests,combine with existing theoretical research,tries to put forward new energy-saving house which is suitable for economic development in Central Shaanxi,climate condition and the demand of villagers' thermal comfort of occupants.This paper investigates villagers' thermal comfort of occupants in central Shaanxi with questionnaire and field test,calculate villagers' human thermal neutral temperature in Central Shaanxi;this paper describes the present situation of rural residence residential environment,indoor thermal environment rural residence of rural residence in central Shaanxi and its existing problems in winter and summer were mainly studied,we consider that room temperature in winter should be improved urgently;This paper haves made the very detailed analysis and resolution to the rural life energy consumption,and pointed out that heating in winter have occupy important part of total energy consumption.In summary,improve human thermal comfort and indoor thermal environment rural residence in winter is the key to study new energy-saving house in Central Shaanxi.Using appropriate technology and endemic architectonics,combine with climatic characteristics in Central Shaanxi,choose solar energy as the main form of central Shaanxi rural residence.Using solar architecture design principle,it gives three schemes which are suitable for central Shaanxi rural solar house.According to solar rate of heating,energy saving rate,adjuvant energy consumption,indoor average air temperature,save money and recovery period evaluate and analyze indexes,carries on the appraisal to thermal performance and economic performance.The conclusion guides the local villagers to make reasonable choice.
