摘　　要：在建立的物理模型基础上,利用CFD软件对专用低温风口送风形式下的4℃、8℃、11℃三种典型温度低温送风系统进行气流组织模拟。并根据模拟的流场进行了详细的分析及对比研究。得出8℃和11℃低温送风的模拟流场较为均匀,工作区气流组织较好。在使用超低温送风温度4℃送风时,应对送风条件或低温风口等进行一定的改进。基于研究结果,给出了不同送风温度下气流组织的建议。Based on the created physics model, the cold air vents systems under the temperature 4 ℃, 8 ℃, 11 ℃ were simulated using CFD software. The simulated result of flow field were analysed and studied minutely. It turns out that, the cold air flow field under 8 ℃, 11 ℃ is more uniform and workspace airflow is better. The air supply condition and air inlet should be improved if the ultra - low supply air temperature was 4 ℃. Based on the results, recommendations of airflow organization under different air temperatures were given.
