P.O. Fanger of Denmark was the first scientist to generalize the physiological basis for predicting human thermal comfort based on activity level, clothing type, air temperature, air velocity, mean radiant temperature, and air humidity. Thus any activity level and clothing type, it is possible to determine combinations of air temperature, mean radiant temperature, air humidity and relative air velocity which would produce optimum thermal comfort. The Fanger approach has been applied successfully to offices and buildings. It would be quite useful to demonstrate that Fanger’s concepts could be applied to tractor cabs. The objectives of this study were as follows: 1. Determine the effect of cab air temperature an velocity on physiological parameters within a tractor cab for summer conditions. 2. Determine in Fanger’s criteria for thermal comfort is applicable to tractor cabs for summer conditions.
