Local thermal sensation and comfort study in a field environment chamber served by displacement ventilation system in the tropics.

The aim of that paper is to investigate the mutual effect of local and overall thermal sensation and comfort in a displacement ventilation environment system in the tropics. For the experiments, 60 subjects were engaged in sedentary office work for 3 hours. They were exposed to three vertical air temperature gradients and three room air temperatures. The results and conclusions are presented.
