An air handling system of a vehicle includes a main housing interchangeable between a first configuration and a second configuration. The main housing has a primary portion configured to convey a cold air flow and a warm air flow therethrough. A secondary portion is interchangeable between a first plenum in the first configuration of the main housing and a second plenum in the second configuration of the main housing.

An HVAC system including a front blower having a first front blower outlet and a second front blower outlet. The first front blower outlet and the second front blower outlet are arranged vertically relative to one another. A joint duct includes a first body portion and a second body portion. The first body portion includes a first duct inlet, which is connected to the first front blower outlet, and a first duct outlet. The second body portion includes a second duct inlet, which is connected to the second front blower outlet, and a second duct outlet. The first duct outlet and the second duct outlet are arranged horizontally relative to one another. An HVAC case defines a first inlet and a second inlet arranged horizontally relative to one another. The first duct outlet is connected to the first inlet, and the second duct outlet is connected to the second inlet.

An air mixing device that is arranged in a space where hot air passing through a heater core of an HVAC module and cold air passing through an evaporator core converge to mix the warm air and the cold air includes: a plurality of warm air guide tubes respectively forming a warm air guide passage for guiding the warm air to a defrost outlet; a first cold air guide provided on a downstream side of the warm air guide tube so that a cold air guide passage guiding the cold air to a vent outlet and a foot outlet is formed between the warm air guide tubes; and a second cold air guide installed to divide air flow through the cold air guide passage. The warm air guide tube is provided with a warm air branching window formed such that a portion of the warm air flowing through the warm air guide passage is branched and mixed with the cold air passing through the cold air guide passage.

An inlet subassembly for a heating, ventilation, and air conditioning (HVAC) system. The inlet subassembly includes a fresh air inlet and a fresh air door movable to control fresh airflow through the fresh air inlet. The inlet subassembly further includes a recirculation air inlet and a partition defining a first airflow channel and a second airflow channel extending from the recirculation air inlet. A recirculation air door is adjacent to the recirculation air inlet and is movable to a closed position restricting recirculated airflow into both the first airflow channel and the second airflow channel, an open position permitting recirculated airflow into both the first airflow channel and the second airflow channel, and a two-layer position in which the recirculation air door restricts recirculated airflow into the first airflow channel and permits recirculated airflow into the second airflow channel.

A vehicular air conditioning system includes an air-conditioning case having a plurality of passages divided by a partition wall, and an ion generator configured to emit anions and cations into the passages. The ion generator includes a plurality of discharge electrodes installed to extend into the passages of the air-conditioning case and configured to emit anions and cations into the passages. The partition wall of the air-conditioning case includes a communication portion configured to bring the passages into communication with each other so that the discharge electrodes installed in the passages face each other in the same space.

A HVAC system for a motor vehicle having a housing, wherein the housing has an air inlet for admitting air and a cold air path in which cold air flows is provided in the housing and a warm air path in which warm air flows is provided in the housing, wherein the warm air path and the cold air path open into a mixing chamber, wherein a mixing flap is provided for controlling the proportion of cold air flowing into the mixing chamber and the proportion of warm air flowing into the mixing chamber, wherein the mixing flap is arranged rotatable about an axis and is driven by a flap actuator which has a drive shaft, wherein a gear with a nonlinear translation characteristic is provided between the mixing flap and the drive shaft.

An HVAC system according to an example of the present disclosure includes a blower rotatable about an axis. The blower has a first blower section and a second blower section fluidly isolated from the first blower section. An inlet assembly at an axial end of the blower includes a first compartment configured to control fluid flow through the first blower section and a second compartment configured to control fluid flow through the second blower section.

A vehicle air-conditioning device includes: an air-conditioning device having an all-seat air-conditioning mode in which air-conditioned air is blown out to occupants of all seats in a vehicle cabin and an individual air-conditioning mode in which the air-conditioned air is blown out to some of the occupants of all seats; a selection device used to select the all-seat air-conditioning mode and the individual air-conditioning mode; and a controller configured to control the air-conditioning device in an air-conditioning mode selected in the selection device. When the vehicle is activated by a remote starter device configured to remotely activate the vehicle, the controller controls the air-conditioning device by switching the air-conditioning mode to the all-seat air-conditioning mode even when the air-conditioning mode selected at previous turning-off of an ignition device is the individual air-conditioning mode.

A vehicular air conditioner includes a casing, a blower fan, and a heating heat exchanger. The air passage in the casing is divided into an outside air passage and an inside air passage. The heating heat exchanger is disposed downstream of the blower fan in the casing. The blower fan is disposed to extend over a first outside air space, a second outside air space, a first inside air space, and a second inside air space in the air passage. The rotational direction of the blower fan is set so that each of the plurality of blades of the blower fan passes through the first outside air space, the first inside air space, the second inside air space, and the second outside air space in this order when the plurality of blade are rotating.
