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.

A method of detecting a need for regeneration of an exhaust particulate filter is described. A first pressure drop is detected in a flow section of an exhaust system which includes the exhaust particulate filter. In addition, an exhaust gas temperature is determined. An exhaust gas mass flow flowing through the exhaust particulate filter is then calculated on the basis of the exhaust gas temperature and the pressure drop. Furthermore, a second pressure drop at the exhaust particulate filter is determined. A need for regeneration is detected when the second pressure drop exceeds a predefined pressure limit value that is dependent on the exhaust gas mass flow. Moreover, an exhaust system for an internal combustion engine is presented which includes an exhaust particulate filter.

An air-conditioning system is provided that may include a first air-processing apparatus, which includes a first inlet formed in a first surface thereof that extends perpendicular to a floor or a ceiling and a first outlet formed in a second surface thereof perpendicular to the first inlet and induces air introduced into the first inlet to exchange heat with refrigerant and to be discharged through the first outlet, and a second air-processing apparatus, which includes a second outlet formed therein so as to be open in a same direction as the first outlet and a second inlet formed therein so as to be open in a same direction as the first inlet. The air-conditioning system may be driven in a combined operation mode in which the first and second air-processing apparatuses operate simultaneously or an independent operation mode in which one of the first air-processing apparatus or the second air-processing apparatus operates.

Data relating to the status of a vehicle, an internal combustion engine powering the vehicle, and various filtration systems that provide filtered fluid to the vehicle and/or internal combustion engine is generated or gathered by an engine control module and a filtration monitoring system. The engine control module and the filtration monitoring system provide the data to a telematics system for transmitting the data to a remote data center (e.g., a cloud computing system, a remote diagnostics system, a maintenance system, etc.). Depending on an availability of a cellular data connection, the data is either sent directly to the remote data center via a network, or indirectly by first transmitting the data over a local connection to an operator device (e.g., a smartphone), which then sends the data to the remote data center once a connection to the network is available.

A filter monitoring system for a filter in a vehicle air conditioner includes a first temperature sensor to detect an air temperature of intake air drawn into an air conditioner case through the filter, a second temperature sensor to detect an evaporator temperature of the evaporator, and a processor coupled to the first and second temperature sensors and coupled to a memory. The processor is configured to calculate an actual change-rate of the evaporator temperature while a compressor is in operation, calculate an expected change-rate of the evaporator temperature based on the air temperature and operation levels of a blower and the compressor by using predetermined data with a properly functioning filter, calculate a degradation degree of the filter by comparing the actual change-rate to the expected change-rate, and output a signal indicating degradation of the filter upon determining that the degradation degree is out of an acceptable range.

An environmental control system for a building, the system including a vent. The vent includes one or more louvers configured to change position between an open position and a closed position to permit air from the air duct to enter a zone of the building or stop the air from entering the zone and a vent circuit configured to operate the one or more louvers based on one or more control commands. The system includes a controller device including a processing circuit configured to receive a selection of an operating profile from a plurality of predefined operating profiles for the vent, each of the plurality of predefined operating profiles indicating an intended use of the zone, determine, based on the operating profile, the one or more control commands, and cause the vent circuit to operate the one or more louvers based on the one or more control commands.
