Study On The Influence Of Health Illumination On Existing Residential Living Rooms Based On Thermal Response

With the continuous improvement of living standards and the advocacy of green building concept,people are increasingly pursuing the quality of indoor environment.The discovery of the third type of photoreceptor cell makes the study of health lighting become a hot spot.Indoor light pollution has a significant impact on people's health,and the light environment is also closely related to the thermal environment.Due to the large stock and low comfort of existing residential areas,their renovation has attracted much attention.But there are few studies on indoor health lighting in existing residential areas.Therefore,this study is mainly focused on the comfort zone of existing residential health lighting under thermal adaptation.Firstly,the research progress and achievements on photothermal comfort and healthy lighting at home and abroad were reviewed and summarized.Secondly,the typical residential environment and indoor photothermal status of dalian were investigated in the form of questionnaire survey and field measurement.The existing problems in existing residential areas were found and their common points were analyzed.As soon as the living room spatial behaviors were classified,which were used as basic parameters for later laboratory simulation.Then the winter living room environment was simulated by the laboratory,Three factors and three levels were tested by orthogonal experiment,by changing the temperature(15?,20?,25?),intensity of illumination(300lx,600 lx,1500lx)and color temperature(3000K,4000 K,6500K)to simulate the sitting room thermal environment,and measuring human physiology,psychology and visual function comprehensive index,to explore human health lighting conditions under different behavior patterns.Finally,model regression is conducted on the data,and comfort parameter interval is proposed to provide guiding parameters for the strategy of dynamic lighting transformation of indoor light environment in existing residential areas.The research content is mainly divided into four aspects:(1)In the form of questionnaire survey and field survey,the spatial layout,internal spatial function and indoor light and heat environment of typical residential areas in dalian were investigated,and the existing problems and common characteristics of existing residential buildings were summarized as the basic research data.(2)The cl-500 a spectrophotometer and the thermal and humidity self-recorder Testo 175H1 were used to conduct the on-site measurement of the indoor temperature and humidity and lighting parameters in the living room and bedroom of the existing residential areas.The living room spatial behavior was classified,and the range of photothermal parameters was extracted,which was then used as the parameter evaluation standard for the subsequent laboratory simulation.(3)Research parameters were extracted and orthogonal design method was used to simulate the photothermal environment of living rooms in existing residential areas by changing temperature,color temperature and illumination.The physiological index values of human good collateral flow,blood pressure and heart rate were measured.Fr ACT software was used to measure the visual efficacy of the samples in the reading environment.The audio-visual and dining environment were investigated by questionnaires to understand the feelings of sample psychological indicators.Using SPSS software for data analysis,to extract the comfortable health lighting conditions under different behavior patterns.(4)SPSS software regression simulation equation was used to explore the relationship between the photothermal comfort index and color temperature,temperature and illumination,and calculate the comfort zone to provide guiding parameters for the transformation of dynamic lighting in existing residential areas.
