With the study results based on numerical simulation and site measurements , the paper simulates a series of thermal environment conditions in a large space of stratified air conditioning varied with different height of nozzle and upper openings, area of upper and bottom openings, inflow velocity through the upper openings with sidewall opening and top opening respectively. And the paper investigates the energy consumption in large space. In any case, upper opening is advantageous to improve the indoor air quality. Top opening is superior to sidewall opening in getting a better temperature field and airflow distribution. And it is seen that the cooling load in the case of sidewall opening is larger than that of top opening. The results of this paper are important to engineering and air-conditioning design. It will provide the theoretical foundation and design basis for structure design.
