The invention relates to a method for reducing energy consumption of an air conditioner of a pure electric vehicle, by adopting a partial external circulation strategy, an air conditioner controller can comprehensively consider user requirements and the actual environment to select the optimal position of a circulating air door, the influence of external low temperature on the temperature in the vehicle is reduced, the effects of updating air and reducing fogging of a user are met, the temperature in the vehicle can be rapidly increased, and the contradiction between heating comfort and energy consumption in winter is effectively relieved; during heating in winter, if a user selects external circulation air intake in order to reduce fogging or update air in a vehicle, under the influence of low temperature outside the vehicle, the PTC consumes high power to heat the air in the vehicle and cannot enable the air in the vehicle to quickly meet the comfort requirement, a part of external circulation strategy is started at the moment, so that the effects of updating the air and reducing the fogging can be met, and the comfort in the vehicle can be quickly improved, and thus the PTC energy consumption is reduced.

    本发明涉及一种降低纯电动汽车空调能耗的方法,通过采用部分外循环策略,空调控制器会综合考虑用户需求和实际环境来选择最优的循环风门位置,减少外部低温对车内温度的影响,使得既满足用户更新空气减少起雾的效果,又能快速提升车内温度,有效的缓和了冬季采暖舒适性和能源消耗的矛盾;冬季采暖时,若用户为了减少起雾或是更新车内空气而选择外循环进气,受车外低温的影响,PTC尽管耗大功率来加热车内空气,没法使车内空气快速达到舒适性要求,此时启用部分外循环策略,可以既满足更新空气减少起雾的效果,又能快速提升车内舒适性,从而减少PTC耗能。
