    • A system and methods are provided for monitoring for a clogged or unclogged state of an air filter in an automotive HVAC system. The HVAC system includes a blower having a blower motor providing a driven airflow. A plurality of outlet registers is controllable to provide a plurality of circulation modes. An evaporator selectably cools the driven airflow, and the air filter passes the driven airflow. The method enters a baseline condition, wherein the baseline condition includes applying a moisture purge to the evaporator and selection of a predetermined circulation mode. The blower motor is controlled to maintain a testing speed. An energization of the blower motor is quantified while maintaining the testing speed. The energization is compared to a base value derived according to the baseline condition with the air filter in an unclogged state. A replacement action is triggered when the energization is greater than the base value.
    • 提供了一种用于监测汽车HVAC系统中空气过滤器堵塞或未堵塞状态的系统和方法。 HVAC系统包括具有提供驱动气流的鼓风机马达的鼓风机。 多个出口寄存器是可控的以提供多个循环模式。 蒸发器可选择地冷却从动气流,并且空气过滤器通过从动气流。 该方法进入基线条件,其中基线条件包括向蒸发器施加湿气吹扫并选择预定的循环模式。 控制鼓风机电机以保持测试速度。 在保持测试速度的同时量化鼓风机马达的通电。 将通电与根据基线条件导出的基值进行比较,空气过滤器处于未堵塞状态。 当通电大于基值时触发更换动作。

    • An HVAC unit is provided for treating air in a passenger cabin of a vehicle. An HVAC housing has a recirculation entry section, a fresh entry section, a blower section, and an output section. A blower is mounted to the blower section for driving an airflow from the HVAC housing out through the output section into the passenger cabin. A recirculation opening is provided proximate the recirculation entry section for providing at least a base recirculation flow from the passenger cabin into the HVAC housing whenever the blower drives the airflow. A climate sensor is fluidically coupled within the base recirculation flow for sensing a climate characteristic representative of the air in the passenger cabin.
    • 提供一种HVAC单元,用于处理车辆的客舱中的空气。 HVAC壳体具有再循环进入部分,新鲜进入部分,鼓风机部分和输出部分。 吹风机安装在鼓风机部分,用于将来自HVAC外壳的气流通过输出部分驱动到客舱中。 在再循环入口部分附近设置有再循环开口,用于当鼓风机驱动气流时,至少提供从客舱进入HVAC壳体的基本再循环流。 气候传感器在基础再循环流动下流体耦合,以感测代表客舱空气的气候特征。
