Effect Of Human Thermal Comfort Based On The Minimum House Of The Clothing Insulation

With the development of economy and the advancement of technology,"People-oriented,energy saving and emission reduction" has become the biggest theme in today's society.As a core part of the research field of building thermal environment,human thermal comfort and building energy consumption fully interpret the meaning of the theme,minimum house also emerged on this basis.The clothing is called the "second skin" of the human body,covering the skin while being affected by external environmental conditions.The difference in clothing due to its unique tiny structure will have a great effect on the human body's sense of cold and heat.Therefore,it is of great significance to study the influence of thermal resistance of clothing on the thermal comfort of human body in minimum house.In this paper,it takes Yangzhou area as representative and college students are selected as the main research object,adopting a combination of on-site questionnaires and numerical simulations,to explore the effects of different clothes on subjective thermal sensation in natural ventilated minimum house in different seasons,and to find the best thermal comfort adjustment measures.The main work and conclusions of this paper include the following two aspects:In terms of survey questionnaire,the methods,contents and measuring instruments for conducting human thermal comfort field test and questionnaire survey in the natural ventilation micro-building room are introduced.The distribution range of indoor clothing thermal resistance of people in different seasons was obtained by data analysis software SPSS23.0.The results showed that the clothing thermal resistance in spring,summer,autumn and winter were concentrated in the range of 0.60-1.20 clo,0.32-0.63 clo,0.60-1.10 clo and 1.05-1.50 clo,respectively.Then,under different seasonal conditions,the relationship between different clothing thermal resistance and human thermal sensation voting TSV,human thermal comfort voting TCV and the influence of gender differences on human thermal comfort were analyzed.And the way that people adjust the thermal sensation in the minimum house indoor in each season is counted.It is concluded that the transitional season can improve the thermal comfort of the human body by changing the thermal resistance of the garment;due to the limitations of clothing in summer and winter,people would prefer to adjust the body's thermal sensation by drinking hot and cold drinks,opening and closing windows and doors,or changing the amount of activity.In terms of numerical simulation,the indoor environmental test results of the four seasons were verified by airpak numerical simulation software,and it is revealed that the dressing method that makes people feel comfortable in the minimum building room is that the thermal resistance value of the clothing distributed between 0.9clo and 1.1 clo in spring,and between 0.8 clo and 1.0 clo in autumn.However,it is unattainable to adjust the thermal sensation by changing the thermal resistance of the garment in winter and summer.It is necessary to add a cold and heat source.Through simulation comparison,the optimal air supply temperature range in summer and winter is between 21 ? to 23 ? and 22 ? to 24 ?.The purpose of this paper is to combine the thermal resistance of clothing with building energy efficiency organically,and to obtain the regulation law of clothing in minimum house,which provides the foundation for further research on the indoor thermal environment of minimum house,supplying reference for future application and promotion.
