Assessment of thermal comfort preferences of industrial facility workers

Abstract

Ensuring thermal comfort in industrial facilities enhances worker productivity and well-being. Achieving optimal conditions necessitates efficient utilisation of HVAC systems. Therefore, ongoing monitoring and improvement are essential to maintain suitable thermal environments within workspaces. This study focused on evaluating the environmental conditions of a facility located in Bolu province about its workforce. Measurements and surveys were conducted to assess conditions separately during summer, winter, and spring. Evaluations considered factors such as age, gender, clothing, and activity levels of the workers. Further analysis of PMV values showed significant differences in thermal comfort, except during heating and autumn, with workers’ subjective perceptions aligning closely with their acceptance of thermal conditions. Individual preferences were especially influential, particularly outside of cooling periods. While no significant differences were found based on gender or age, activity levels significantly affected thermal comfort, highlighting the importance of considering these factors in industrial settings.
