- Abstract:
- Heat stress is a common problem throughout industry that depends also on some climatic parameters, such as the mean radiant temperature, air humidity, velocity and temperature. WBGT (wet bulb globe temperature) index is assumed in international standards as thermal stress index in job environments. It can be estimated directly, following the ISO 7243, by means of globe temperature, natural wet-bulb temperature and air temperature measurements or indirectly by means air temperature, humidity and velocity, and the radiative medium temperature. The aim of the present work is the experimental comparison between the two different methodologies to evaluate the WBGT index. The analysis is carried out in a wide range of thermodynamic properties and also for air velocity less than 0.5 m s-1.
