驻车空调出风口风速均匀性分析与结构优化
Analysis and Structural Optimization of Airflow Velocity Uniformity at Outlet of Parking Air Conditioner
摘要
Abstract
A design validation test is conducted on a specific model of parking air conditioning to measure the airflow at the vents.Then,computational fluid dynamics(CFD)is used to simulate the airflow inside the air conditioner.To address the issue of uneven airflow,an optimization scheme is proposed and its effectiveness is verified using rapid prototyping technology.The results show that CFD simulation can accurately model the airflow inside the air conditioner,with a simulation and test error of only 3.9%for the average airflow speed at the vents.The uneven airflow from the parking air conditioning is mainly due to the eccentric position of the vent relative to the grille and the varying projection area of the blower impeller at the vent.By adding a guide vane to optimize the transition connection mechanism inside the air conditioner,the issue of uneven airflow can be effectively improved.The maximum ratio of the highest to the lowest airflow speed is reduced from 1.33 to 1.08,and the difference between the maximum and minimum airflow speed is decreased from 1.8-2.8 m/s to 0.4-0.6 m/s.关键词
