基于ANSYS CFX 参数化的某酒店中庭气流组 织方案的浅探 胡艺萌 程向东 武汉纺织大学 摘 要：为探讨本项目酒店中庭及大厅的分层空调与顶送顶回气流组织方案的温度场与 其它流场的关系，本文采用标准 k- ε湍流模型，运用ANSYS CFX 软件进行了该方案的气流 组织计算模拟，在确定设计区域的中庭部分采用中送顶回送风方式的前提下，对比与分析了 模拟计算结果，并以风口尺寸、风口气流扩散角、送风速度、空调区域平均温度为参数，求 得设计区域的最佳送回风口类型、布置与送回风温度。结果证明，通过ANSYS CFX 进行气流 组织模拟计算能够真实有效地展示不同设计条件下的温度场和气流场情况，而这一气流组织 模拟方法能帮助设计人员预测气流组织设计方案的可行性和有效性，利于减少空调能耗并提 高室内空气品质和人体舒适度，对气流组织设计计算有重要意义。 关键词：CFX 参数化； 分层空调；空调设计；气流组织模拟计算；温度场；速度场 Abstract: In this project, for the aim of exploring the relationship between the stratified air conditioning in the atrium and lobby and the temperature field as well as the other flow fields of top-supply and top-return airflow distribution, this article utilizes the standard k-εturbulence model and Ansys CFX software to simulate the airflow distribution. After ensuring that the middle-supply and top-return airflow scheme in the atrium, simulation results are compared and analyzed, parameters containing inlets and outlets sizes, airflow diffusion angle of inlets, wind speed and average temperature of air conditioning areas are set to get the optimization of the types and arrangement of return grills as well as the temperature of inlets and outlets in design area. The results show that the simulation calculation of airflow conducted by Ansys CFX could show the temperature and airflow field in different design conditions, and this method can help designers to predict the feasibility and effectiveness of airflow organization design schemes. It is of great significance to reduce air conditioning energy consumption and improve indoor air quality and human comfort, designing calculation of airflow organization as well.
