An Investigation of Thermal Comfort for Mold, Welding and Turning Technicians and the Effects on Performance in Naturally Ventilated Area

Kemal Furkan Sökmen [1]


In this study, thermal comfort measurements were made for mold, welding, and turning technicians in naturally ventilated industrial establishments. Metabolic rates were determined as 100 W/m2 for welding and turning and 190 W/m2 for mold technicians. The clothing insulation factor was calculated as 0.68 clo. The measurements were done  in 3 different companies on 17-19 July 2017 during working hours without stop working. In terms of PMV findings, it was determined that the thermal comfort conditions are not met according to the ASHRAE standard. As for the WBGT value, it was determined that there was heat pressure on 17.07.2017 and there was no heat pressure on 18.07.2018 on all the employees. On 19.07.2017, it was determined that there was a heat pressure after 13:00 for mold technicians and after 17:00 for welding and turning technicians. Calculated PMV values were compared with the survey results and  ıt was determined that results were compatible with values. It was made firm that people who were overweight and obese felt their working environment warmer than normal weight worker. The performance loss ratios which are dependent on ambient temperature were calculated and compared with the literature and was determined that they are compatible.
