Research On Indoor Thermal Comfort Of Old Industrial Building Renovation Space Facin The Needs Of National Fitness

The State Council’s "Opinions on Strengthening the Construction of National Fitness Venues and Facilities to Develop Mass Sports" clearly stated: "Effectively solve the bottleneck problem that restricts the planning and construction of fitness facilities,and form a good atmosphere for the general public to participate in sports and fitness." Considering the shortage of urban land and the value of idle factories,regenerating industrial buildings into sports venues becomes an effective way to solve the bottleneck problem of current sports facilities planning and construction.Urban residents have high requirements for indoor thermal comfort in sports venues.The research on human thermal comfort of sports personnel in sports venues based on industrial building regeneration has become an important proposition for industrial building regenerated into sports venues,which is especially important for indoor sports fitness comfort experience in cold northern regions.This paper selects the Running fitness club,a typical case of the regeneration of industrial buildings into sports venues in Changzhi City,Shanxi Province,as the research object,and uses a combination of subjective questionnaire survey and objective physical environment actual measurement to obtain the human comfort feeling vote in the stadium,as well as the test results of outdoor and indoor environmental parameters;Combined with environmental parameter testing and comfort data,perform the operating temperature calculation and thermal sensation linear fitting based on votes of thermal sensation,thermal comfort,and temperature acceptability to explore the relationship between the physical environment and human thermal comfort;Combining data statistics,physical environment and human thermal comfort correlation law to build PMV model and TSV model,and achieve PMV correction through the comparison and verification of PMV and TSV;Construct the revit model of Running fitness club in Changzhi City,conduct thermal comfort simulation to get the variation map of average radiation temperature and PMV,and propose human thermal comfort enhancement measures according to its variation law and characteristics.The main conclusions are as follows:(1)By exploring the correlation between environmental parameters and human thermal comfort,it is found that there is a linear relationship between the two.Thermal sensation shows a decreasing trend when the operating temperature rises,while thermal comfort and temperature acceptability show an increasing trend.(2)Through the subjective questionnaire survey on human thermal comfort of sports personnel in the arena and the percentage of the questionnaire results based on thermal sensation,it is concluded that human thermal comfort in the arena shows positive development without negative feedback,which proves that human thermal comfort in the arena is relatively good.(3)It is verified that there is indeed a scissors difference between PMV and TSV,and obtain a modified model by linearly correcting PMV based on the actual thermal sensation value.(4)According to the thermal comfort simulation law,it is concluded that the thermal comfort of human body is greatly affected by sunlight.Based on its variation rules and characteristics,it is proposed to carry out zoning control of the venue,design a reasonable ratio of window to wall and window to floor,and select a reasonable window opening method to improve the thermal comfort of the human body in the venue.
