An air conditioner apparatus for electric vehicles includes: an air conditioning case installed under an under body of a vehicle, and configured to communicate with an interior of the vehicle through an outlet formed through an upper portion of the air conditioning case and circulate conditioned air therein; an HVAC module provided inside the air conditioning case, and configured to adjust temperatures of indoor air and outdoor air and to provide the conditioned air to the interior of the vehicle; and a heat exchange module provided below the HVAC module inside the air conditioning case and configured to exchange heat with the HVAC module depending on whether or not the HVAC module performs a heating or cooling operation.

A motor vehicle includes a passenger space and a HVAC system. The HVAC system includes a heater, an air conditioner, and ducts configured to heat and/or cool air to the passenger space. The HVAC system is configured to increase humidity of air while the air is flowing through the HVAC system, and to introduce a sanitizing agent into air while the air is flowing through the HVAC system. A controller is configured to actuate the HVAC system to circulate humidified air containing the sanitizing agent through the passenger space to neutralize pathogens that may be present in the passenger space.

An HVAC assembly for a vehicle. The HVAC assembly has an HVAC case with a rear blower and an evaporator. A rear blower scroll directs airflow generated by the rear blower to a lower portion of the evaporator. An airflow conduit is configured to direct airflow generated by a front blower to an upper portion of the evaporator. An airflow divider separates airflow generated by the rear blower from airflow generated by the front blower. The airflow divider divides the HVAC case into an upper area above the divider and a lower area below the divider. A defrost outlet and a front face outlet are at the upper area of the HVAC case above the divider. A front foot outlet and a rear airflow outlet are at the lower area of the HVAC case below the divider.

A method of heating and cooling at least one zone of a passenger compartment in a vehicle includes the steps of (a) pumping a coolant through an auxiliary coolant loop, (b) changing a temperature of the coolant utilizing a first heat exchanger associated with a refrigerant loop via an expansion device in the cooling mode, and a second heat exchanger associated with the refrigerant loop and (c) moving air through a third heat exchanger through which coolant moves, that third heat exchanger positioned in the passenger compartment, and at least one vent positioned within at least one zone of the passenger compartment.

An air conditioner is disposed in a vehicle in which a driving device of a traveling power source is housed in an outer space separated from a cabin by a partition wall. The air conditioner includes: a temperature control unit that controls a temperature of air blown into the cabin; and plural air distribution ducts connected to the temperature control unit to guide temperature-controlled air having a temperature controlled by the temperature control unit to predetermined positions in the cabin. The temperature control unit is disposed in the outer space together with the driving device. Intermediate parts of the air distribution ducts located at least between the outer space and the cabin are bundled together and extended through a single insertion hole formed in the partition wall.

A refrigeration cycle device including a first pressure reducing valve, a first evaporator that exchanges heat between the refrigerant decompressed in the first pressure reducing valve and air, a second pressure reducing valve that is disposed in parallel with the first pressure reducing valve; a second evaporator in which the refrigerant decompressed in the second pressure reducing valve to absorbs heat from a battery; a third pressure reducing valve that reduces the pressure of the refrigerant evaporated in the second evaporator; and a controller configured to control opening degrees of the second pressure reducing valve and the third pressure reducing valve. The controller performs a limit control for controlling the opening degree of the second pressure reducing valve to an opening degree of smaller one of a battery cooling opening degree and an air cooling opening degree.

A vehicular air conditioning device includes an air conditioning case having first, second case introduction ports and first, second case discharge ports, and a fan. The first, second case discharge ports are offset upward and downward in an up-down direction relative to a rotation axis, respectively. A first inner guide surface of an inner guide plate is located on the one side of a second inner guide surface in the left-right direction. Air introduced through the first case introduction port is guided by the first inner guide surface to be drawn from a first passage into the fan, the air being blown upward to flow through the first case discharge port. Air introduced through the second case introduction port is guided by the second inner guide surface to be drawn from a second passage into the fan, the air being blown upward to flow through the second case discharge port.

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.
