A HVAC system (100) includes a housing (10) with at least one first inlet (20) and at least one second inlet (30) formed thereon, at least one first door (20a), at least one second door (30a) and an intermediate door (40). The first inlet (20) and the second inlet (30) is for ingress of a first fluid stream and a second fluid stream inside the housing (10). The first door (20a) and the second door (30a) moves with respect to the first inlet (20) and the second inlet (30) respectively to define an open configuration, a closed configuration and a partially open configuration thereof. The intermediate door (40) is disposed between the first inlet (20) and the second inlet (30) and moves between a deployed and an un-deployed configuration to respectively disrupt and allow fluid flow there across. The intermediate door (40) is a sliding door.

Methods and systems are provided for a cooling assembly for a vehicle. In one example, the cooling assembly may be a non-rectangular cooler positioned in a front end of the vehicle with an entry duct continuous with the non-rectangular cooler and arranged upstream of the non-rectangular cooler and an exit duct also continuous with the non-rectangular cooler and arranged downstream of the non-rectangular cooler.

A heating, ventilating, and air conditioning (HVAC) system of a vehicle is provided. The system replaces a cooling water circuit having a complex configuration and a separate heat pump system for recovering waste heat of an electric vehicle by changing an air flow path for supplying heating and cooling air and secures an indoor space by disposing an HVAC in an engine room.

A vehicular air conditioning system includes: a heat pump side refrigerant circulation line including a compressor, a water-cooled heat exchanger, a heat pump mode expansion valve, an air-cooled heat exchanger, an air conditioner mode expansion valve and an evaporator, the heat pump side refrigerant circulation line configured to generate cold energy in the evaporator in an air conditioner mode and to generate heat in the water-cooled heat exchanger in a heat pump mode, the air-cooled heat exchanger configured to allow a refrigerant to exchange heat with an ambient air in the air conditioner mode and the heat pump mode; and a heat exchange air switching part configured to switch the type of the air heat-exchanged in the air-cooled heat exchanger depending on the air conditioner mode or the heat pump mode.

A computer includes a processor and a memory, the memory storing instructions executable by the processor to, heat a passenger cabin of a vehicle, actuate a thermal sensor to collect temperature data in the passenger cabin, identify a surface in the passenger cabin that has a temperature below a temperature threshold, and actuate one or more components to sanitize the identified surface.

A HVAC system (100) includes a housing (10) with at least one first inlet (20) and at least one second inlet (30) formed thereon, at least one first door (20a), at least one second door (30a) and an intermediate door (40). The first inlet (20) and the second inlet (30) is for ingress of a first fluid stream and a second fluid stream inside the housing (10). The first door (20a) and the second door (30a) moves with respect to the first inlet (20) and the second inlet (30) respectively to define an open configuration, a closed configuration and a partially open configuration thereof. The intermediate door (40) is disposed between the first inlet (20) and the second inlet (30) and moves between a deployed and an un-deployed configuration to respectively disrupt and allow fluid flow there across. The intermediate door (40) is a sliding door.

A system for heating a cabin of a vehicle can include: a liquid-cooled charge air cooler configured to receive a liquid, to receive heated air from one of a turbocharger and a supercharger of the vehicle, to cool the heated air via the liquid, thereby heating the liquid, to output the cooled air to an intake manifold of an engine of the vehicle, and to output the heated liquid; and a multi-function heat exchanger connected to the liquid-cooled charge air cooler, the multi-function heat exchanger configured to receive the heated liquid outputted by the liquid-cooled charge air cooler, to generate heated air via the heated liquid, and to output the heated air into the cabin of the vehicle, thereby heating the cabin of the vehicle.

A vehicle air conditioner, wherein an air conditioner of an integrated heat pump system enables the improvement of cold air and warm air mixing characteristics so as to decrease left-right temperature differences, enables the implementation of independent left-right air conditioning, and enables the sufficient securement of an interior space of the vehicle.

An air-conditioning unit for a vehicle includes an air conditioning case, a blower, and a rectifying mechanism. The blower has a blower fan rotating around a fan axis and arranged in an in-case passage of the air conditioning case, and blows out air drawn from one side in an axial direction of the fan axis by rotation of the blower fan. The rectifying mechanism is arranged downstream of the blower fan in the in-case passage, and the air passes through the rectifying mechanism. The blower fan is arranged so that the other side of the fan axis that is opposite to the one side extends toward a downstream side of the in-case passage. The rectifying mechanism suppresses a swirling flow generated by the rotation of the blower fan in the air blown out from the blower fan as compared with the blown-out air prior to flowing into the rectifying mechanism.

A door of an air conditioner for a vehicle, which can prevent damage and distortion by bending during assembly and reinforce strength due to a plate-shaped sliding door with flexibility. The door is disposed inside an air-conditioning case to adjust the degree of opening of an air passageway, and includes a door body formed in a plate shape and formed to be able to slide in the air-conditioning case, and a reinforcing part formed from at least one side of the door body in a thickness direction and extending in an axial direction, which is perpendicular to a sliding direction of the door body.
