M any researches entally studied in term s of different air supply volum es and on the air distribution of airconditioning system s w ith a outdoor m eteorolog ical param eters in a largespace building downside air supply in largespace bu ildings provide design w hich is air conditioned w ith a low sidewall air supply. The considerations[24] . The vertical temperature gradient (VTG) expermi ental results show that the indoor vertical tem perature is am ajor focus because of energy saving and comfort. It is distributions under different condition are smi ilar. The expermi entally observed that theVTG was 3 to 5 /m in a m axmi um vertical temperature difference (MVTD ) is up to [ 5] room w ith a height of26m . However, to date, expermi en about 20 , and it linearly changes w ith the solair tal studies in large space build ings are rarely reported. In temperature. T he indoor ve
