摘要
运用CFD数值模拟方法和Airpak计算软件对建筑空调室外机进行气流模拟,根据其速度场、温度场、压力场的模拟结果,发现不同的出风方式以及风口形状对气流有较大影响。另外,通过对有室外风影响的情况的模拟,结果表明室外风速对气流有一定的影响,但是影响并不十分显著。经过对原方案的改进,满足了室外机的工作条件,基本达到了所需的要求。
In this paper, the airflow of the outdoor-air conditioner was simulated by using CFD numerical simulation methods and Airpak softwire to simulate. According to the results of velocity field, temperature field and pressure field, it is found that different ways of outflow and the shape of tuyere have much influence on the airflow. Besides, by simulating the situation of wind outside the building, it is concluded that wind outside has some influence on the airflow. However, the influence is not very obvious. By improvement of the former method, the working condition for the outdoor unit is satisfied and the terminal aim is attained.
