Abstract: A thermal management system for a vehicle includes a heat exchange unit coupled with a compartment of the vehicle via an interface in the compartment. A container is moveable between a first position and a second position. The container is configured to be in fluid communication with the heat exchange unit via the interface in the first position.

Abstract: A multi-zone climate control system for vehicles includes a front HVAC unit, a powered blower, and a heater core. The front HVAC unit is adapted to condition air provided to first and second front zones. The front HVAC unit further includes a cold air outlet connected to the powered blower. Cold air from the cold air outlet of the front HVAC unit passes through the powered blower and enters the heater core. The heater core is configured to control a temperature of conditioned air supplied to at least one rear zone of the passenger compartment.

Abstract: A multi-zone climate control system for vehicles includes a front HVAC unit and one or more additional units that can be configured to provide conditioned air to one or more rear climate zones. The front HVAC unit is adapted to condition air provided to at least one front climate zone. The front HVAC unit may include a cold air outlet that supplies cold air to an electrically-powered heater positioned in a console of the vehicle. The electrically-powered heater includes an electricity-to-air heat exchanger to control a temperature of conditioned air supplied to at least one rear zone of the passenger compartment. The system may include an auxiliary climate control system having an auxiliary heater core and an auxiliary evaporator positioned in a rear portion of the vehicle to provide conditioned air to one or more rear climate zones.

Abstract: A motor vehicle includes a motor compartment, a passenger compartment and a firewall separating the motor compartment from the passenger compartment. The motor vehicle also includes a heating, ventilation and air conditioning system. That heating, ventilation and air conditioning system includes an HVAC inlet subassembly and an HVAC air distribution subassembly in the passenger compartment and a transition duct in the motor compartment directing an airstream from the HVAC inlet subassembly to the HVAC air distribution subassembly.

Abstract: A vehicular air-handling system includes a blower assembly for a vehicle having a fan and a return-air baffle operable between a fresh-air position. The fan is in communication with a fresh-air duct and a recirculating position and the fan is at least partially in communication with a recirculating duct. A noise-attenuating end of the recirculating duct is positioned below an instrument panel of the vehicle and oriented substantially perpendicular to a portion of a floor below the instrument panel, wherein noise from the fan drawing air through the recirculating duct is directed into the floor below the instrument panel.

Abstract: A noise tone occurring at a blade passing frequency in a blower for an automotive HVAC system is suppressed. The blower includes a centrifugal fan and a scroll body disposed around the fan. An outlet extends from the scroll body to conduct an air flow from a cutoff point of the scroll body. An inlet is coupled to the scroll body defining an inlet throat comprising an arcuate ring extending between a base and an annular end coaxially disposed over the fan. A partial-perimeter wall extends upstream from the arcuate ring having a height between about 4% and about 6.5% of an inner diameter of the annular end. The wall spans a perimeter portion of the circumference of the throat between about 120° and about 180°. As a result, noise at the blade passing frequency is suppressed without any significant reduction in air flow.

Abstract: A heat exchanger assembly having first and second heat exchangers and a seal. The seal may be disposed on the first heat exchanger and may have an elongated portion that extends toward the second heat exchanger to direct the flow of cooling air.

Abstract: A plenum assembly for carrying air in a supply system includes a duct including an opening formed with an inner surface through which air can flow; a door supported for movement between multiple positions which distributes air to the desired output path; and a seal secured to the door. In a vehicles HVAC system, numerous doors are utilized to provide comfort to the passengers based upon user input. The potential exists that some positions of the doors my lead to unwanted noise. A modification to the seal of the door with variable gap widths alleviates this issue and improves satisfaction.

Abstract: The invention relates to a system for producing energy from a coolant (4) that comprises an electricity generator (13) combined with a turbine (2) that is supplied by an air flow (30) that is admitted into the base of a tower. The tower is equipped with various blade stages (40) that are made integral with a central shaft (2) that drives the generator, and, alternately, heat exchanger stages (10). Said blades are driven by the rise of heated air as it rises in the tower by thus creating an artificial vertical wind. The coolant (4) supplies the heat exchangers (10) by descending through the latter from the one that is located at the uppermost level.
