Biophysical Evaluation of the Wet Globe Temperature Index (Botsball) at High Air Movements and Constant Dew Point Temperature,
Abstract
A study was conducted to verify whether high temperatures (from 41 degrees C to 54 degrees C) (normal lighting) at different wind movements (up to 9 m.s-1) at constant dew points affect the wet globe temperature index measured with a Botsball. A new meter (Reuter-Stokes) was also tested which digitizes the values of globe temperature, air and wet bulb (ventilated) temperatures. The values are integrated to a wet bulb globe temperature 8WBGT). The reading from this meter, as well as the Botsball, were tested against a Yellow Springs Instrument (USI) standard set-up for natural wet bulb, air and globe temperatures, and against psychrometric values. All data were collected on-line by a computer in an all-weather tropic/wind chamber and procedures were designed according to standard practices (ASHRAE Fundamentals). The data were subjected to statistical analysis, reversing the order in which one index was the dependent or independent variable. A multiple correlation analysis was also done in which the Reuter-Stokes (R-S) WBGT< YSI WBGT and Botsball readings were the dependent variables versus psychrometric readings of ambient air temperature and ambient water vapor pressure.
