A blower unit includes a casing defining a first passage and a second passage, a first internal-external air switching member, a second internal-external air switching member, and a partition defining an opening. During a two-layer internal/external air mode, the first internal-external air switching member opens an external air inlet and closes an internal air inlet and the second internal-external air switching member closes the external air inlet and opens the internal inlet, so that the external air is directly introduced into the first passage through the external air inlet and the external air in the second passage is introduced into the first passage through the opening of the partition and the internal air is directly introduced into the second passage through the internal air inlet and the internal air in the first passage is introduced into the second passage through the opening of the partition.

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.

An air handling system of a vehicle comprises a housing defining an inlet section. The inlet section includes a first inlet portion and a second inlet portion. The first inlet portion includes a first recirculation inlet configured to receive recirculated air originating from a passenger compartment of the vehicle and a first ambient air inlet configured to receive ambient air originating from an ambient environment. The second inlet portion includes a second recirculation inlet configured to receive recirculated air originating from the passenger compartment of the vehicle and a second ambient air inlet configured to receive the ambient air originating from the ambient environment. A first air distribution door and a first baffle door are disposed in the inlet section to selectively control a distribution of the recirculated air and the ambient air entering the first inlet portion. A second air distribution door and a second baffle door are disposed in the inlet section to selectively control a distribution of the recirculated air and the ambient air entering the second inlet portion.

An embodiment air conditioner for a vehicle includes a blower unit on an outer surface of a dash panel, the outer surface being opposite an inner surface facing an interior space of the vehicle, the blower unit including a blower fan and a filter, an air conditioning unit on the outer surface of the dash panel and coupled to a side of the blower unit between the blower unit and the interior space of the vehicle, and a distribution unit disposed on the inner surface of the dash panel and located between the air conditioning unit and air conditioning ducts provided in the interior space of the vehicle, wherein each of the blower unit, the air conditioning unit, and the distribution unit is coupled to be individually detachable.

An air conditioner for a vehicle, includes a blower unit, having a blower fan and a filter, disposed on an outer surface opposite to an interior space in a dash panel of the vehicle. The air conditioner includes a HVAC unit disposed on the outer surface opposite to the interior space to introduce air from the blower unit. The HVAC unit has a cooler and a heater therein to divide the air introduced from the blower unit into cold air and hot air through the cooler and the heater and to discharge the air and has a distribution unit disposed on an inner surface facing the interior space to introduce the cold air and the hot air generated by the HVAC unit. The distribution unit has front and rear seat doors configured to adjust a degree of mixing of the cold air and the hot air.

An air-handling system includes an evaporator core and a downstream arranged heater core disposed in an air-handling casing. A primary flow path is formed within the air-handling casing and leads to a primary zone of a passenger compartment. The primary flow path is divided into a primary cool air pathway bypassing the heater core and a primary warm air pathway passing through the heater core. A secondary flow path is formed within the air-handling casing and leads to a secondary zone of the passenger compartment. The secondary flow path includes a secondary cool air pathway branching from the primary flow path downstream of the evaporator core and a secondary warm air pathway branching from the primary flow path downstream of the heater core. The secondary cool air pathway bypasses the heater core and the secondary warm air pathway passes through the heater core.

In a mobility including a negative pressure space and method for controlling a pressure of the mobility in which the mobility is used a general vehicle in normal times, and when a special situation such as transferring infectious disease patients occurs, an internal space includes a general space and a negative pressure space by a partition wall, so that the infectious disease patients are safely transferred through the negative pressure space and the spread of infectious diseases is prevented. As a result, the usability of a vehicle is increased, and it is possible to respond to such special situation.

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.

Provided is an air-conditioning device for a vehicle, including: a cooling device configured to cool air passing through a duct; a heater core, which is arranged in the duct on a downstream side of airflow with respect to the cooling device, and is configured to use an engine coolant as a heat source to heat the air; a water valve provided in a coolant circulation system on an upstream side of the heater core; and a controller configured to control those components, in which the controller is configured to decrease an opening amount of the water valve in a predetermined cooling mode. The control is configured to, when the opening amount of the water valve is decreased, decrease a rotational speed of a compressor of the cooling device, and increase a target evaporator temperature of an evaporator of the cooling device, thereby decreasing cooling performance of the cooling device.
