The composite air supply for tall space buildings has always grabbed the researchers’ attention. Tall and square-built spaces generally have more complex building structures, along with challenges such as high system energy consumption, poor sewage disposal efficiency, and difficulty in heat dissipation. In addition, tall and square-built space buildings will have a greater impact on the flow of indoor airflow with respect to the air inlet/outlet selection, layout position, and spray angle. Therefore, in order to choose a more suitable plan and create a more reasonable airflow organization form, we use CFD numerical simulation method to simulate the airflow organization of a tall and open-duplex-structured factory in mainland, China. By setting different air supply parameters and air supplier column parameters, the composite air supply scheme combining the tuyere type and the air supplier column type is evaluated respectively. The experimental results show the feasibility and innovation of this scheme to increase the exhaust air volume, reduce energy consumption, and improve the heating effect in tall and square-built space buildings, and also provide a stereotype for the future application of examples on air distribution in similar buildings.
