Study on the Influence of Globe Thermometer Method on the Accuracy of Calculating Outdoor Mean Radiant Temperature and Thermal Comfort

With global warming and the rapid development of urbanization, outdoor thermal environment is deteriorating. More more research focuses on comfort. The globe thermometer method widely used in than half studies, but there a large error compared with six-direction method. In order to explore accuracy results its impact subsequent comfort indicators, this study carried out year-round comparative experiment under multiple working conditions outdoors cold areas meteorological parameters such as shortwave radiation, wind speed, direction show that continuous increase radiation reduces black bulb less 60%, instantaneous change speed will make deviation mean temperature obtained by exceed 5 °C. influence index mainly reflected condition high strong summer. Taking standard, gives scope application method; taking human body calculation model PET an example, universal optimization for detailed division heat transfer proposed, so it can get accurate rigorous conclusions evaluation complex environment.
