The invention discloses a fresh air circulation system of a vehicle air conditioner and a control method of the fresh air circulation system of the vehicle air conditioner, the fresh air circulation system of the vehicle air conditioner comprises an air inlet assembly, an internal and external circulation air door, an air blower assembly and an air exchange air door, and the air inlet assembly is provided with an external circulation port and an internal circulation port which are communicated with a cab and the interior of the air inlet assembly; the air inlet assembly is communicated to an inlet of the air blower assembly; the internal and external circulation air door is arranged on the air inlet assembly so as to selectively open the external circulation port and close the internal circulation port or close the external circulation port and open the internal circulation port; the air exchange air door is arranged between the outlet of the air blower assembly and the evaporator core assembly so as to selectively communicate the outlet of the air blower assembly with the air exchange opening communicating with the outside or disconnect the outlet of the air blower assembly with the air exchange opening. By means of the ventilation air door and the ventilation opening, the problem that harmful gas and particles in a vehicle are discharged slowly through the pressure relief opening is solved, and the driving safety and comfort are improved.
本发明公开了一种车用空调新风循环系统及车用空调新风循环系统的控制方法,车用空调新风循环系统包括进风总成、内外循环风门、鼓风机总成及换气风门,进风总成上开设有连通驾驶室与进风总成内部的外循环口和内循环口,进风总成连通至鼓风机总成的入口;内外循环风门设置在进风总成上,以选择性打开外循环口并关闭内循环口或者关闭外循环口并打开内循环口;换气风门设置在鼓风机总成的出口与蒸发器芯体总成之间,以选择性地连通鼓风机总成的出口和与外界连通的换气口或者断开鼓风机总成的出口与换气口。本发明通过换气风门和换气口,解决了泄压口排出车内有害气体及颗粒慢的问题,提升了驾乘安全及舒适性。
