A vehicle includes an inverter, a climate control system, and a coolant system. The climate control system includes a housing, and a heater core and an electric heater disposed within the housing. The coolant system includes conduit arranged to circulate coolant through the inverter and the heater core. The inverter is disposed upstream of the heater core.

A heater core for performing heat exchange between a coolant and ventilation air to be blown to the interior of a vehicle so as to heat the ventilation air is disposed in a water circulation circuit for circulating a coolant in an engine EG for outputting driving force necessary to move the vehicle. When the temperature of the coolant discharged from the engine EG is low, a heat transport refrigeration cycle device, serving as a heat transport unit for absorbing heat from a downstream coolant at a position downstream more than the heater core and dissipating the heat absorbed from the downstream coolant to an upstream coolant at a position upstream more than the heater core, is operated to increase the temperature of the coolant introduced into the heater core until the temperature of the coolant reaches the temperature necessary to heat the interior of the vehicle, without operation of the engine EG.

A method for natural ventilation of a vehicle interior includes steps of: determining, by a controller, formation of an interior negative pressure in an interior space while driving of a vehicle is maintained as an internal air mode, determining, by the controller, an over-production of a harmful gas in an exhaust gas using an air-to-fuel ratio or an Accelerator Position Scope (APS), in an air conditioning system; regarding satisfaction of the formation of the interior negative pressure and satisfaction of the over-production of the harmful gas as an entry condition and mixing an exterior air into the interior space so as to mitigate the interior negative pressure in the internal air mode; and after mixing the exterior air, regarding the non-satisfaction of the over-production of the harmful gas as a cancellation condition and blocking the exterior air.

A vehicle compartment temperature control device includes: a first interior member including a temperature control mechanism layer that can adjust the temperature of a leg of the occupant in a first region, that is, a front portion and the like. The vehicle compartment temperature control device also includes a second interior member disposed above the first interior member and including a temperature control mechanism layer in a second region, that is, a steering and the like that can adjust the temperature of a part above the leg and is different from the temperature control mechanism layer in the first region. The vehicle compartment temperature control device also includes an ECU. The ECU performs control such that the temperature of the temperature control mechanism layer in the first region is higher than the temperature of the temperature control mechanism layer in the second region.

An air-conditioning system for a vehicle includes: a blower unit connected to an internal air flow path and an external air flow path and configured to selectively suction or discharge air; a flow path housing configured to guide air suctioned through the blower unit to the interior of the vehicle; a carbon dioxide capture module configured to selectively capture carbon dioxide contained in the air flowing into the flow path housing; and a door disposed between the flow path housing and the carbon dioxide capture module in order to selectively open or close the flow path housing.

System and apparatus for carbon dioxide detection within an automobile. Specifically, this disclosure describes apparatuses and systems for optical gas detection in a stationary and moving vehicle. There is a need for a such a system to prevent loss of life and contribute to a safer traffic environment. This disclosure provides a highly efficient optical measurement system based on principals of optical absorption spectroscopy. It detects the presence of neglected children and animals and changes the vehicle's interior environment accordingly so as to preclude many potentially dangerous conditions. The present disclosure can also optimize ventilation for a driver. To this end, a driver can maximize alertness and attentiveness.

An air handling system of a vehicle comprises a housing defining an inlet section. The inlet section includes a recirculation inlet in fluid communication with a passenger compartment of the vehicle and a fresh air inlet in fluid communication with an ambient environment. An air distribution door is disposed in the inlet section for controlling a distribution of air entering the inlet section through the recirculation inlet and the fresh air inlet. A baffle door is disposed in the inlet section for selectively reducing a flow area through the fresh air inlet to accommodate a ram air pressure induced by motion of the vehicle relative to fresh air of the ambient environment.

The present invention relates to a method for controlling an air conditioner for a vehicle, which includes a blower having a structure divided into a plurality of inlets and a plurality of outlets. The method may include: detecting or predicting, by a controller, one or more of an inside temperature of the vehicle, an outside temperature, a temperature of an engine serving as a heating source, an indoor humidity of the vehicle, CO.sub.2 concentration and rear seat passenger information; and comprehensively determining, by the controller, an outdoor state of the vehicle, an indoor state of the vehicle and a user's intention based on the detected or predicted information and a blower setting mode, and controlling an inlet door of the air conditioner according to one of a plurality of designated steps.

A heating, ventilation, and air conditioning (HVAC) system including an HVAC assembly, a set of pins, mode doors, a mode plate, an actuator, and an HVAC control module. The mode doors control airflow from the HVAC assembly. A position of each mode door is controlled by a corresponding pin of the set of pins. The mode plate includes (i) a set of grooves, (ii) a first adjustment path and (iii) a second adjustment path. The first adjustment path causes a first pin of the set of pins to move toward a center. The second adjustment path causes the first pin to move away from the center of the mode plate. An HVAC module selectively actuates the actuator to causes the mode plate to rotate in at least one of a passive direction and the active direction in response to receiving a mode request.

A motor vehicle air-conditioning line valve arrangement includes a line valve having an air-conditioning line body which is of substantially closed design in a transverse plane, and a fiber nonwoven arranged on an inside in the air-conditioning line body and having a nonwoven mat to which a large number of nonwoven fibers are fixed. The nonwoven fibers are fixed to the nonwoven mat at one end and configured to be electrostatically charged by the nonwoven mat. An electrical charge generator is electrically connected to the nonwoven mat and configured to electrostatically charge the fiber nonwoven, so that the electrostatically charged nonwoven fibers straighten toward a center of the air-conditioning line body in such a way that they close an open flow cross section of the air-conditioning line body.
