Research on indoor thermal comfort of urban residence in winter in a typical city of hot summer-cold winter region
In response to the poor indoor thermal comfort in residential buildings during the winter in a typical city of hot summer-cold winter region,measurements of objective thermal environment parameters such as indoor air temperature,black globe temperature,relative humidity and air flow velocity were conducted in several residential buildings in Hefei,a typical city in hot summer and cold winter area,and a questionnaire survey was conducted on residents'indoor clothes,subjective thermal sensation evaluation and thermal expectation on the test site.The survey results show that the indoor environment in the residential rooms in the area tends to be cold,which is lower than the thermal comfort range specified in current indoor thermal environment standards,indicating relatively poor objective thermal conditions.Although the interviewees generally show good acceptance of the indoor thermal and humid environment,nearly half of them express a desire for a warmer indoor environment,highlighting a high demand for improvements in the winter thermal environment of residential buildings.Statistical methods were used to conduct regression analysis on the sample data,and the relationship between the PMV and TSV and indoor operating temperature was obtained.The difference between the theoretical prediction model results and the measured values was analyzed,and the actual thermal neutral temperature is 18.5℃,and thermal comfort temperature range of residents in winter is between 14.4 and 22.6℃with 90%acceptable rate.The research findings can provide a reference for the design,construction,and evaluation of indoor thermal comfort in hot summer-cold winter region.
