Provided is a vehicle HVAC system. Outside air (34) is drawn from the outside air inlet through the HVAC unit (14), and recirculated air (44) is drawn through the recirculated air inlet. An air intake management system includes first and second variable speed blowers (52, 54) and an air flow regulator (56). The air flow regulator defines a plurality of flow paths (60, 62, 64, 66) through which external air or recirculated air is drawn by the first blower (52) or the second blower (54). A valve arrangement regulates the flow of air through at least one of the flow paths. Control of the operating speeds of the valves and the blower enables control of the amount and relative proportion of outside air and recirculated air through the HVAC unit (14). One air flow path for outside air is permanently open and has an air mass flow sensor (70) to monitor air flow.
车辆HVAC系统。外部空气(34)从外部空气进气口经HVAC单元(14)被抽吸,并且再循环空气(44)通过再循环空气入口被抽吸。一种进气管理系统包括第一和第二变速鼓风机(52、54)以及空气流量调节器(56)。空气流量调节器限定了多个流动路径(60、62、64、66),通过第一鼓风机(52)或第二鼓风机(54)经这些流动路径抽吸外部空气或再循环空气。阀装置调节经流动路径中的至少一个流动路径的空气流量。对阀和鼓风机的运行速度的控制使得能够控制通过HVAC单元(14)的外部空气和再循环空气的量和相对比例。用于外部空气的一个空气流动路径是永久打开的并且具有空气质量流量传感器(70)以监测空气流量。
