乘员舱驾驶员位置微环境及人体热舒适分析

Analysis on the Microenvironment and Human Thermal Comfort of the Driver Position in the Passenger Compartment

摘要:

采用实验与数值模拟相结合的方法对夏季乘员舱内驾驶员位置的微环境及人体热舒适性进行了研究。首先通过11个不同工况分析了空调送风温度、送风速度、太阳辐射强度、太阳高度角以及环境温度对驾驶员位置不同部位微环境的影响，接着基于Stolwijk人体热调节模型，采用Berkeley热舒适评价模型对乘员热舒适状态进行了模拟，得到了各影响因素对人体热感觉及热舒适的影响程度。

Abstract:

The microenvironment and human thermal comfort of the driver position in the passenger compartment in summer were studied by means of experiment and numerical simulation. Firstly, the influence of air supply temperature and air supply velocity of air conditioner, solar radiation intensity, solar altitude angle and environmental temperature on the microenvironment of different parts of the driver’s position was analyzed under 11 different working conditions. Then, based on Stolwijk human thermal regulation model, the Berkeley thermal comfort evaluation model was adopted to simulate the thermal comfort state of passengers, and the influence degree of various influencing factors on human thermal sensation and thermal comfort was obtained.
