Research On Optimization Design Of Attached Sunsapce In Severe Cold Rural Area Based On Indoor Luminous And Thermal Environment

The world population is rising,the industrial development speed accelerating,various countries and regions,the demand for energy is also increasing,in this state of sustainable energy utilization has become an inevitable trend of large amount of rural residential construction area in our country face is wide,but because of restricted by factors such as economy,technology,has been in a rugged design stage,low energy consumption high thermal comfort,indoor light environment bad cold region of Inner Mongolia,long and cold climate is more outstanding problems of the rural residential heating energy consumption How to make full use of natural resources and adopt design strategy to reduce heating energy consumption under the premise of improving indoor comfort of rural residential buildings is an urgent problem to be solved in rural residential areas.In this paper,through on-the-spot investigation found that the central region of Inner Mongolia in China rural residence,additional sunshine type between the passive solar house has received a degree of application but additional between sun type of passive solar technology is not very perfect,no enough theory as the support,most of the sunshine building is in a state of follow one’s inclinations,this creates an indoor thermal comfort is still very poor,and is accompanied by additional after sun between indoor daylighting is insufficient,is not conducive to the improvement of farmers’ quality of life Therefore,this paper conducts theoretical analysis on the influence of related parameters of additional sunshine on indoor thermal environment and light environment in the central region of Inner Mongolia,and studies by means of numerical simulation.The research conclusion will provide theoretical basis for the design and construction of additional sunshine interroom passive solar house in the severe cold region of Inner Mongolia.Way at first,this paper through on-the-spot investigation system for the farmhouse,the surrounding areas of Inner Mongolia baotou research main research object for baotou areasurrounding additional type farmhouse between sun and ordinary farmhouse,the main research information for the homestead the heating energy consumption of rural residents’ basic information and thermal environment comfort daylighting environmental comfort,through field test sampling of the different types of rural residential physical environment parameters such as temperature natural light illumination Through two different types of farmhouse flat measurement data arrangement and analysis,found the existing between the farmhouse than ordinary farmhouse on the indoor temperature has a degree of improvement,indoor average temperature about 2 or so higher,but the indoor average illuminance value lower 223 lx concluded local farmhouse due to causes such as construction technology material selection for additional type farmhouse between sunlight for indoor temperature ascension is not big but low falling indoor light environment.Second against additional sunlight between the passive solar houses can affect indoor thermal comfort and indoor temperature and indoor light environment factors are studied,mainly including additional depth window wall between the sun better than roof material using energyplus simulation software to establish the model and simulation experiment,and discusses the influencing factors on the annual heating energy consumption between the sun and in the master bedroom daylighting coefficient influence law among different sunlight through the window wall than the farmhouse,coefficient of energy consumption and indoor daylighting analysis can be obtained when the window wall ratio 0.9 farmhouse indoor best lowest energy consumption and indoor daylighting coefficient in the depth of 1.4 m 2 m when choosing a toughened glass as roof material can reduce indoor energy consumption situation as far as possible to reduce the impact on the indoor light environment when the depth of 0.1m,1.3 m between the sunlight through the analysis of the energy efficiency in lighting the daylighting of the insulation board efficiency value less than the lighting efficiency of the toughened glass roof,which concluded that in the depth of 0.1 m,1.3 m,considering the farmhouse,energy consumption and the coefficient of daylighting,should choose between the insulation board as the sun roof material.Finally on both the farmhouse,the sunshine after the construction of the overall scheme design,combined with the fourth chapter simulation content analysis between sun energy saving and efficiency between sun to select the required materials,and the scale of the combination between the sun and materials to optimize the interior space design for the local residents combined with their own economic conditions between the construction of additional sun provide appropriate type between the sun,is among the local promotion additional sunshine type passive solar house provide data support.
