Abstract: An air duct assembly for a vehicle air distribution system includes a first duct defining a first passage and a second duct defining a second passage separate from the first passage. The first and second passages are fluidly connected to a common outlet for flowing air to a windshield of the vehicle. The assembly further includes a third duct defining a third passage for flowing air to a side glass of the vehicle. The second and third passages are fluidly connected to a common inlet for receiving air from the blower motor. The third passage is fluidly connected to a lateral outlet that is separate from the common outlet, with the lateral outlet flowing air to a side glass of the vehicle. The assembly further includes at least one acoustic baffle disposed within the second passage and configured to reduce a transmission of the blower noise through the second passage.

Abstract: An HVAC system for a motor vehicle includes a filter that absorbs odors and gases in a cabin of the motor vehicle and desorbs the odors and gases when heated, and a heater that is turned on to heat the filter during cool ambient conditions. The heater is turned off during warm ambient conditions and warm ambient air is utilized to heat the filter. The desorbed odors and gases are purged from the cabin of the motor vehicle.

Abstract: A vehicle air filtration system includes a housing having a first air filter having a first filtration level and positioned upstream of a second air filter having a second filtration level that is different than the first filtration level and a bypass door selectively operable to bypass air flow around the second air filter through a bypass passage.

Abstract: Methods and systems for controlling a climate control system of a vehicle are provided. The provided system and method determines whether an auxiliary seat is in fluid communication with the climate control system. When an auxiliary seat is in fluid communication with the climate control system, commands are generated for the climate control system to assure that a combination of airflow temperature and airflow velocity to the auxiliary seat are within configurable targets.

Abstract: A method for controlling a thermal comfort control system for ride share vehicles includes providing a plurality of occupant seats in a vehicle cabin and controlling a cabin set temperature using a cabin comfort control system configured to adjust a plurality of HVAC functions. At least one thermal comfort parameter is adjusted at a number of the plurality of occupant seats using at least one seat comfort control system. Adjusting the at least one thermal comfort parameter causes the cabin control module to adjust the set temperature of the vehicle cabin.

Abstract: The present teachings provide for a vehicle heating, ventilation, and air conditioning (“HVAC”) assembly including a drive member, a driven member, a connecting member, a guide member, a first door, and a second door. The connecting member can be rotatably coupled to the drive member and the driven member and can be configured to be moved by the drive member to rotate the driven member. The guide member can be in cooperation with the connecting member and configured to restrict movement of the connecting member as the connecting member is moved by the drive member. The first door can be configured to be rotated by the drive member between a first position and a second position. The second door can be configured to be rotated by the driven member between a third position and a fourth position.

Abstract: The present teachings provide for an HVAC assembly. A first flue can be configured to fluidly couple a first heat exchanger to a mixing flue. A second flue can be configured to fluidly couple a second heat exchanger to the mixing flue. A door can inhibit fluid communication through the second flue when in a first position. The door can inhibit fluid communication through the first flue when in a second position. The door can permit fluid communication through the first and second flues when in a third position. The third flue can be configured to fluidly couple the first heat exchanger to a portion of the second flue downstream of the second heat exchanger and upstream of the mixing flue when the door is in the third position.

Abstract: Disclosed is a vehicle HVAC system that provides for installation, serviceability, or replacement of at least one actuator servo without removal of the HVAC assembly from the vehicle. As due to the tight space limitations, the present invention provides for at least one fastener-less mounting element of the servo assembly to be attached to the HVAC assembly, without the need for additional fasteners which would require additional space to access with a tool.

Abstract: An evaporator and a heater may be accommodated in a case. A tunnel in a tubular shape forms a tunnel passage. The case may form an evaporator passage and a heater passage. The evaporator passage may be located on a downstream side of the evaporator and extended without passing through the heater. The heater passage may be located on a downstream side of the heater. The tunnel may extend from the heater passage through the evaporator passage toward an inner wall of the case.

Abstract: A fresh air and recirculation air switching case using a rotary door, since an introduced air flows along an inner surface of a circumferential wall of the rotary door, a convex grid is formed on an inner surface of the circumferential wall of the rotary door. In this system, the air flow directed toward a suction inlet is prevented from becoming turbulent behind the rotary door and the air flow noise can be suppressed.

Abstract: A heat exchanger includes multiple tubes, multiple fins, and a partition wall. The multiple fins are stacked alternately with the tubes to form a core including a first section and a second section. The partition wall partitions between the first section and the second section. The first section has multiple drain passages in the vicinity of the partition wall.

Abstract: A housing for a vehicle HVAC system includes a case and a drainage port that drains fluid from the case of the housing. The drainage port includes a spout and defines a first fluid passage and a second fluid passage. An outlet of the first fluid passage and an outlet of the second fluid passage may be adjacent to each other at the spout. The first fluid passage fluidly couples a first region of the case to the spout, and the second fluid passage fluid fluidly couples a second region of the case to the spout. Based on the pressure of the first region and the second region, fluid flowing through the first fluid passage or the second fluid passage accelerates at the outlet of the respective passage to form a vacuum at the spout.
