摘要

合理的出风口叶片角度调节可以最大地发挥空调系统的能力，有效地改善整车的车内速度场和温度场分布，提高整车舒适性。本文对某A级车室内全尺寸模型进行简化处理，对出风口叶片送风角度范围进行等分处理，分别进行仿真计算和试验验证，结合热舒适性评价指标，对乘员舱进行温度场和速度场进行评价。结果表明：整车舒适性评价时最合理的出风口叶片角度调节位置为出风口第一排叶片的角度为50°（出风口的吹风角度从前排乘员的肩膀上侧，脸颊外侧吹出）。

Abstract

The correct outlet blade angle can maximize the capacity of an air-conditioning system and effectively improve the flow field and temperature distribution in the car

thereby greatly improving the thermal comfort of passengers. In the current study

a class A vehicle model with a scale ratio of 1:1 was simplified and the range of outlet blade angle was equally divided. Simulations and experiments were carried out in conjunction with assessment of a thermal comfort evaluation index to evaluate the flow field and temperature distribution. The results showed that the optimal air outlet blade angle was 50°

i.e.

the air was blown to the upper side of the front passenger's shoulder and the outside of the passenger’s cheek.
