基于自然通风建筑的热舒适模型研究 Abstract Withtheincreasingattentiontoenergysavingandenvironmentalprotection,naturalventilationhasbecomeanimportantfactorforbuildingdesign.Inthispaper,aheatcomfortmodelbasedonnaturalventilationarchitectureisstudied,whichcanbeusedtoevaluatethethermalcomfortofnaturalventilationbuildings.Firstly,thedefinitionandclassificationofnaturalventilationareintroduced.Secondly,thefactorsaffectingheatcomfortinnaturalventilationbuildingsareanalyzed,suchastemperature,humidity,airflowvelocity,andairquality.Thirdly,thecomfortevaluationindexofnaturalventilationisdiscussed,includingcomfortrange,comfortrate,andcomfortthermalsensation.Finally,acasestudyiscarriedouttoverifythefeasibilityoftheheatcomfortmodel.Theresultsshowthattheheatcomfortmodelbasedonnaturalventilationarchitecturecaneffectivelyevaluatethethermalcomfortofnaturalventilationbuildings,andprovideareferenceforthedesignandevaluationofnaturalventilationbuildings.
