An air conditioner for a vehicle includes an air conditioning case and a case interior member in the air conditioning case. The case interior member includes a tunnel member and a tunnel exterior guide wall. The tunnel member defines a tunnel channel therein and is arranged in a downstream space defined in an air conditioning case. The tunnel exterior guide wall is configured to guide an air to flow from a warm air passage to an outside of the tunnel channel. A first direction along which the tunnel exterior guide wall extends is closer to a direction, which is opposite to the one direction along which the air flowing from a cool air passage into the downstream space, as compared to a second direction along which the tunnel guide wall extends.

An HVAC module for an automotive vehicle includes a housing defining an air inlet, an upper front zone outlet, a lower front zone outlet, and a rear zone air outlet. An evaporator and a heater downstream of the evaporator are disposed in the housing. The air inlet of the housing is divided by a first divider into an OSA portion exclusively receiving outside air and a REC portion exclusively receiving recycled air. Each of the evaporator and the heater has a respective OSA portion receiving the outside air and a REC portion receiving the recycled air entering the HVAC module through the inlet. A second divider between the evaporator and the heater directs the outside air from the REC portion of the evaporator to the REC portion of the heater. Two temperature doors control access of separate partial streams of the recycled air from the evaporator to the heater.

Some embodiments provide a vehicle climate control system for controlling climate conditions in various cabin regions of a vehicle cabin, where the climate control system is configured to control one or more vehicle components to change the set of climate conditions associated with one or more cabin regions to approximate a set of optimal comfort conditions. The climate control system controls various vehicle components to control climate conditions, including window assemblies, sunroof assemblies, etc. The climate control system determines optimal comfort conditions which optimize perceived temperature of various occupant body parts and maintain various climate characteristics within one or more sets of thresholds. Output configurations of various vehicle components can be determined based at least in part upon determined optimal comfort conditions of various cabin regions. Output configurations can be generated based at least in part upon various control mode priorities.

An air conditioner includes a blower unit, a blowing duct, and an air switching portion. The blower unit is configured to blow cold air and warm air simultaneously. The blowing duct includes a target blowing portion through which air is sent to a space that is an air-conditioning target, and a non-target blowing portion through which the air is sent to a space that is not an air-conditioning target. The air switching portion is configured to switch between a cold air supply state in which the cold air is sent to the target blowing portion while the warm air is sent to the non-target blowing portion, and a warm air supply state in which the warm air is sent to the target blowing portion while the cold air is sent to the non-target blowing portion.

An air conditioning unit for a vehicle includes: an air conditioning case, a blower that draws air from an opening and blows the air radially outward from its rotation axis, a cooler disposed upstream of the blower, and a heater is disposed downstream of the blower. The air conditioning case includes an upper bypass passage through which the air bypasses the heater on an upper side of the heater, a lower bypass passage through which the air bypasses the heater on a lower side of the heater, a first opening provided downstream of the upper bypass passage, and a second opening provided downstream of the lower bypass passage. The opening of the blower faces an air outflow face of the cooler. A passage area of the upper bypass passage is larger than a passage area of the lower bypass passage.

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.

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.

A heating, ventilation, and air conditioning (HVAC) airflow distribution module with an outlet closing mechanism for a vehicle including a driver face airflow outlet defined by an HVAC module. A passenger face airflow outlet defined by the HVAC module having a center portion and a side portion. An adaptor including a door driving mechanism to control a telescoping door sub-assembly, which is mounted at the passenger face airflow outlet and is movable between a retracted position at which the telescoping door sub-assembly does not obstruct the airflow through the passenger face airflow outlet by being packaged away from outlets, and any one of a plurality of extended positions at which the telescoping door sub-assembly obstructs the side portion or both the side and center portions of the passenger face airflow outlet at different blocking levels when no passenger is present to save energy, improve fuel economy, and/or increase battery life.

An HVAC system for a vehicle. The HVAC system including an evaporator case, a heater case, and a blower case. The heater case is in cooperation with the evaporator case to receive airflow from the evaporator case. The heater case includes a heat source and defines front passenger cabin airflow outlets and rear passenger cabin airflow outlets. The blower case is in fluid communication with the evaporator case and includes a single airflow generator that generates airflow through the evaporator case, through the heater case, and to both the front passenger cabin airflow outlets and the rear passenger cabin airflow outlets.
