Abstract: In this paper, the exergy method is combined with the prediction heat strain model to establish a worker exergy model and study whether exergy transfer can express the thermal comfort of workers. The results show the exergy transfer changes in a 'single peak' curve with the temperature increase. Exergy transfer reflects the influence of temperature, humidity, wind speed, and labour intensity. A method was proposed to judge workers' thermal comfort based on the difference between the current exergy transfer and the maximum exergy transfer. This provides a new idea for studying workplace thermal comfort and ventilation cooling.

Keywords: exergy analysis; exergy transfer; worker; thermal environment.
