A climate control system for a vehicle includes a front-end or first heat exchanger configured to thermally condition airflow from an environment external to a vehicle cabin, a rear-end or second heat exchanger configured to thermally condition airflow from the vehicle cabin, a recirculation path configured to return airflow from the second heat exchanger to the vehicle cabin, and an extraction path configured to vent airflow from the second heat exchanger to the environment external to the vehicle cabin. Various operational modes of the climate control system direct airflow to either the recirculation path or the extraction path.

Embodiments herein relate to vehicle filter monitoring systems and methods. In an embodiment, a filter monitoring system is included having a filter sensor device configured to generate data reflecting a filter condition value of a filter and a geolocation circuit configured to determine a present geolocation of a vehicle. The system can also include a system control circuit configured to generate or receive local contaminant concentration values at the present geolocation, evaluate the filter sensor device data to determine at least one of the filter condition value and a change in the filter condition value, and generate at least one of a maintenance recommendation and a routing recommendation based on the local contaminant concentration values, time spent at the geolocation of the vehicle, duty cycle of the vehicle, the filter condition value, and a change in the filter condition value. Other embodiments are also included herein.

Filter apparatus (6) in particular passenger compartment filter apparatus, for example for a motor vehicle (1), comprising a filter element (8) having a filter medium body (9) and a frame (10) surrounding the filter medium body (9), wherein the frame (10) features opposite lateral surfaces (11, 12), a plurality of engagement elements (22a to 22d), and a filter housing (7) featuring, on two opposing wall sections (24, 25), in each case two engagement counter elements (28a to 28d) in which in each case one of the plurality of engagement elements (22a to 22d) can be accommodated in a positive fitting manner, wherein the engagement counter elements (28a to 28d) in each case are designed as a groove in the respective wall section (24, 25) of the filter housing (7) and feature: an insertion section (31) which, when the filter element (8) is mounted in the filter housing (7), permits an insertion movement of the respective engagement element (22a to 22d) substantially along the throughflow direction (L), and a locking section (32) connected to the insertion section (31) and angled with respect to the insertion section (31), wherein a respective engagement element (22a to 22d) is disposed on a respective lateral surface (11, 12) of the filter element (8) when the filter element (8) is mounted in the filter housing (7), extends away from the filter medium body (9), and is held in a respective locking section (32).

An air quality system includes an air precleaner, a filter identification component, and a control module. The air precleaner has a precleaner housing and a filter disposed inside the precleaner housing. The filter identification component is positioned within the precleaner housing at a first position and is mounted on the filter. The control module is positioned within the precleaner housing at a second position and is configured to emit an electrical field and communicate with the filter identification component via the emitted electrical field.

In the application, since the flow of air outside the vehicle compartment flowing through the upstream heat exchange part and the flow of air outside the vehicle compartment flowing through the downstream heat exchange part are opposite flows, a second heat exchanger through which the air outside the vehicle compartment flowing from the first fan through the downstream heat exchange part flows, a first heat exchanger is an orthogonal heat exchanger, the second heat exchanger that is a component of a refrigeration cycle execution system, the air in the vehicle compartment, which flows in from the inside air inlet by the rotation of the second fan and is discharged from the outlet outside the vehicle through the first heat exchanger, and the air outside the vehicle compartment, are exchanged with the first heat exchanger, it can be miniaturized along with the improvement of electricity cost.
