An Investigation of Thermal Comfort for Mold, Welding and Turning Technicians and the Effects on Performance in Naturally Ventilated Area
Inthis study, thermal comfort measurements were made for mold, welding, andturning technicians in naturally ventilated industrial establishments.Metabolic rates were determined as 100 W/m2forwelding and turningand 190 W/m2 for mold technicians. The clothing insulationfactor wascalculated as 0.68 clo...

| description | Inthis study, thermal comfort measurements were made for mold, welding, andturning technicians in naturally ventilated industrial establishments.Metabolic rates were determined as 100 W/m2forwelding and turningand 190 W/m2 for mold technicians. The clothing insulationfactor wascalculated as 0.68 clo. The measurements were done in 3 differentcompanies on17-19 July 2017during working hours withoutstopworking. In terms of PMV findings, itwasdetermined that the thermalcomfort conditions are not met according to the ASHRAE standard.As forthe WBGT value, it wasdeterminedthat there was heat pressure on17.07.2017 andthere wasno heat pressure on 18.07.2018on allthe employees. On 19.07.2017, it was determined that there was a heat pressureafter 13:00 for mold technicians and after 17:00 for welding and turningtechnicians. Calculated PMV values were compared with the survey resultsand ıt was determined that results were compatible with values. Itwasmade firmthat people who were overweight and obese felt theirworking environment warmer than normalweightworker.Theperformance lossratios which aredependent on ambient temperature were calculated and compared with theliteratureand was determined that they are compatible. |
