The invention discloses a fresh air return device of an electric automobile air conditioning system and a control method of the fresh air return device. The fresh air return device comprises a fresh air inlet, a return air outlet, a fresh air door, a return air door, a fresh air return door motor and a fresh air door transmission mechanism. The fresh air door and the return air door are arranged between the fresh air inlet and the return air outlet; the fresh air return door motor simultaneously controls the opening, closing and opening angles of the fresh air door and the air return door through the fresh air return door transmission mechanism; the fresh air return door motor is connected with an automobile air conditioner fresh air return control module and is controlled by the automobile air conditioner fresh air return control module; the automobile air conditioner fresh air return control module controls the fresh air door and the return air door through the fresh air return doormotor according to the weighted air outlet value, the external temperature limit, the anti-fog algorithm requirement and the PM2.5 requirement. The device is matched with an automobile air conditionerto work, the potential safety hazard that a glass windshield is fogged under the condition that the air conditioner is turned on in summer and HP or PTC is turned on in winter is eliminated, the energy can be saved, and the endurance is improved.

    本发明公开了电动汽车空调系统新回风装置及其控制方法,包括新风进气口、回风出气口、新风风门、回风风门、新回风门电机和新回风门传动机构;新风风门和回风风门设置于新风进气口和回风出气口之间;新回风门电机通过新回风门传动机构同时控制新风风门和回风风门的开启、关闭和打开角度;新回风门电机与汽车空调新回风控制模块连接,由汽车空调新回风控制模块控制;汽车空调新回风控制模块根据加权出风值、外温限制、防雾算法需求、PM2.5需求通过新回风门电机控制新风风门和回风风门。本发明配合汽车空调工作,消除夏天开空调和冬季开HP或PTC的情况下,玻璃风挡起雾的安全隐患,还能够节能、增加续航。
