纯电动汽车内个性化采暖的热舒适试验

Thermal Comfort of Personal Comfort System in Electric Vehicles

纯电动汽车内采用个性化采暖(座椅加热、腿部加热、脚部加热)装置进行局部加热,实测了人体局部和整体的热舒适情况以及各部位的加热功率。结果表明:个性化采暖装置在车外温度为0~8℃时能显著提高驾乘者局部和整体的热舒适情况,尤其是脚部和手等肢末部位;在加入新风系统的情况下,与传统空调采暖的能耗相比,个性化采暖装置的节能最高可达总能耗的81.4%。

The electric vehicle adopts personalized heating(that is seat heating,leg heating and foot heating)device for local heating.Thus the local and overall thermal comfort of human body and heating power of each part were tested.The results indicate that the personalized heating device can significantly improve the local and overall thermal comfort of the occupants when the atmosphere temperature is 08℃,especially feet and hands.Compared to the electricity consumption with traditional air conditioning heating,the personalized heating device can save up to 81.4%of the total heating energy under the condition with fresh air supplying.
