Results of this study showed that spot cooling improved significantly the thermal conditions for the occupants and increased the acceptance of the thermal environment. Heat strain on the subjects decreased. Mean skin temperature of 33°C and sweat evaporation rate 35 g.h*1.m"2 were found to correspond to neutral thermal sensation and comfortable vote. Relationship between subjects* rating of the thermal environment and predictions by PMV and ET* indices showed good correlation but the individual differences were large. Sweat evaporation rate measured was higher than sweat evaporation rate calculated by SRindex
