摘　　要：对某汽车驾驶舱内流场进行了数值模拟,利用PMV-PPD评价了夏季不同外部辐射温度、送风速度和送风温度下的人体热舒适性,计算了不同工况的空调制冷量,并分析数据。结果表明:在相对高温、高速送风状态的驾驶员热舒适性,与相对低温、低速送风状态的驾驶员热舒适性相同,前者在测试工况的节能率为10.74%~16.92%,平均节能13.3%。The flow field in the cockpit of an automobile was numerically simulated,and the thermal comfort of the human body under different air supply speeds and air supply temperatures at different external radiation temperatures in summer was evaluated by PMV-PPD.The air conditioning cooling capacity under each working condition was calculated,and the data were analyzed.The experimental results show that under the conditions of relatively high temperature and high air supply speed,the thermal comfort of the driver is the same as that under relatively low temperature and low air supply speed conditions.The energy saving rate of the former in the test condition is 10.74%-16.92%,and the average energy saving rate is 13.3%.
