Variation in time of the perception of local discomfort parameters
The aim of the present research was to investigate the temporal change of the AMV votes of subjects exposed to the joint effect of warm ceilings and draught. The paper investigates whether the value of AMV remains constant or it changes over time under a constant thermal environment? To answer this question, we performed human subject studies involving 10 men and 10 women. The results were analyzed in function of time. The most important result is that, throughout the 180-min studies, in the 5-15 oC radiant temperature asymmetry interval between warm ceiling and floor, with a DR=15% and DR=25%, draught rate, the AMV value was not constant but showed a decreasing trend. Furthermore, there was a significant discrepany among the votes of females and males.
