摘　　要：通过改变个性化送风的送风距离、送风温度和送风速度,模拟分析了五种工况下的人员座位区的温度场和速度场.结果表明,适当的调整个性化送风的送风距离,既有助于减小对人员的冷吹风感,又能达到节能的效果,模拟得出的最佳送风距离为20～40cm.Based on the different air supply distances, air temperatures, and air velocities of personalized ventilation, the temperature and velocity distributions of occupant zones under five working conditions have been simulated. The results show that properly adjusting the air supply distance is helpful to solve cold draft problem and also achieves energy saving effect. The optimum air supply distances simulated range from 20 to 40 cm.

关 键 词：个性化送风 送风距离 冷吹风感 节能
