Thermal Comfort Differences with Air Movement Between Students and Outdoor Blue-Collar Workers

Abstract

In order to explore the comfort zone of airflow and thermal comfort differences with air movement between students and outdoor blue-collar workers, the experiment was carried out in a climate chamber in Chongqing university. The research shows that the range of the outdoor blue-collar worker (0.7 m/s–2.89 m/s) is wider than that of the students (0.9 m/s–2.76 m/s). In addition outdoor blue-collar workers are not sensitive to changes of the temperature compared to the students. The upper threshold of the acceptable temperature and humidity is different between the two groups. The upper limit of the white-collar workers is 30 °C/70%, while the outdoor blue-collar workers could maintain their thermal comfort with air movement even in 32 °C/90%.
