Numerical simulation method is adopted to optimize the design of air flow distribution in China Pavilion. Four cases of different supply air velocity and temperature based on the same cooling capacity are simulated. Through comparing draught sensation (DR), ADPI index, energy consuming and so on, indoor thermal comfort and energy-saving are analyzed. The results show that, under the case which the supply air velocity is 2m/s, the indoor air velocity in occupied zone is mainly 0.2m/s, draft sensation is about 8%, the temperature, velocity field and energy consuming are basically meet the requirement of thermal comfort and energy saving.
Keywords. Numerical simulation; draught sensation; thermal comfort; energy saving
