The Applicability Analysis Of Solar Radiation Heat And Night Ventilation On Residential Buildings In Northern Xin Jiang

Located in the middle of the mainland,Northern Xinjiang is a temperate continental climate.The prevailing wind direction In summer is north and northwest.With abundant solar energy resource and great difference in temperature during day and night,the place has a typical inland climate.In the region to control indoor sunlight,timely use of night ventilation and other energy-saving technologies,can reduce building energy consumption,and create a harmonious indoor environment.This dissertation based on the fully understanding for the climate characteristics in Northern Xinjiang,analyzed the applicability about solar radiation heat and night ventilation on local residential buildings and put forward optimization suggestions on building structure,layout and operation.The main research contents:(1)By referring to the relevant literature,analyzing the characteristic of climate and geography of the Northern Xinjiang.The conclusion is drown: with abundant wind and solar power and great difference in temperature during day and night,the use of unique meteorological resources is an important way to reduce residential energy consumption in the region.(2)Through software simulation of typical residential building energy consumption in Northern Xinjiang,it is concluded that the region heating is the main part of the building energy consumption,accounting for 60%.In accordance with the relevant norms and standards,proposed building energy conservation strategy for the Northern Xinjiang.(3)Through theoretical analysis and Energy Plus software simulation,analyzed the influence of solar radiation heat on indoor thermal environment and energy consumption in residential buildings in Northern Xinjiang.It is concluded that making full use of solar heat in winter,can reduce heating energy consumption at different degrees in different periods;Solar radiation heat gain is greater than the index of indoor heat load in south room during noon time of the heating trough and partial heating steady phase.Indicating that to stop heating can also maintain a suitable room temperature in the period of noon in the south room.(4)Through theoretical analysis and Energy Plus software simulation,analyzed the influence of night ventilation on indoor thermal environment and energy consumption in residential buildings in Northern Xinjiang.In the summer night taking ventilation measures timely,can effectively improve the indoor thermal environment,reduce the energy consumption of air conditioning refrigeration,The top room night ventilation effect is the best,the middle room night ventilation effect second,the bottom of the worst.(5)On the premise of positive and active use of renewable energy,Analysed design optimization and operation strategy of residential building in Northern Xinjiang.Indicating that palisade structure heat insulation technology is more and more mature,increasing the window-to-wall ratio,can increase the sun radiation heat through the south window in the winter and the ventilation volume through the north window in the summer,to reduce the heating energy consumption during the heating period and the energy consumption of the air conditioning during the cooling period.
