A heating, ventilation, and air condition (HVAC) unit may include a casing, an evaporator, a heater core, and a first damper. The casing may define a front airflow passageway, a rear airflow passageway having an inlet, and first and second outlets in fluid communication with the rear airflow passageway. The evaporator and the heater core may be disposed within the casing. The first damper may be disposed within the casing between the evaporator and the heater core and movable between a first position in which airflow is directed to the heater core and a second position in which airflow is directed away from the heater core. Airflow across the evaporator from the front airflow passageway to the rear airflow passageway is directed to the first and second outlets when the first damper is moved from the first position toward the second position.

Systems and methods can determine whether an air conditioning (AC) system of the vehicle is being operated under a maximum cooling condition. Responsive to determining that the AC system is being operated under the maximum cooling condition, it can be determined whether vehicle fluid temperatures meet associated predetermined thresholds. If none of the vehicle fluid temperatures meet the associated predetermined thresholds, a heater core valve can be switched to a closed position to reduce a flow rate of the coolant through a heater core. If one or more of the vehicle fluid temperatures meet the associated predetermined thresholds, the heater core valve can be switched to an open position to increase the flow rate of the coolant through the heater core. Such systems can force coolant to flow through the heater core to reduce vehicle fluid temperatures even when the AC system is being operated under the maximum cooling condition.

An air conditioner for a vehicle has a housing. The housing defines an air passage therein, includes a suction port, and houses a blower fan. The blower fan draws an air from the suction port and discharges the air into the air passage. The housing includes a facing portion that faces an inlet defining member including an air inlet. The facing portion includes the suction port. The facing portion has a rib that protrudes from the facing portion toward the inlet defining member. The facing portion and the rib define at least a part of an air guiding passage that guides the air from the air inlet to the suction port.

An air conditioning apparatus for a vehicle may include a cooling duct provided with a cooling duct inlet at a first end of the cooling duct, and a cooling duct indoor outlet and a cooling duct outdoor outlet at a second end cooling duct, and including an evaporation core disposed in the cooling duct, a heating duct provided with a heating duct inlet at a first end of the heating duct, and a heating duct indoor outlet and a heating duct outdoor outlet at a second end of the heating duct, and including a condenser disposed in the heating duct, and an overlapping duct provided by overlapping the cooling duct with the heating duct, the evaporation core and the condenser being disposed respectively at an upstream and a downstream of an air flow, and the evaporation core and the condenser may be connected with each other on one refrigerant passage.

The present invention relates to a vehicle air conditioning device capable of improving sealing ability by doubly sealing a defrost vent of an air conditioning case, and increasing the amount of airflow discharged inside a vehicle while simultaneously preventing an increase in the amount of force needed to actuate a face door and, more particularly, to a vehicle air conditioning device comprising: a ball; the air conditioning case in which a floor vent is formed; a defrost door installed to be rotatable via rotation shafts respectively inside the air conditioning case, and opening and closing each of the vents; the face door; the defrost vent for discharging air entering through the floor door and an air inlet inside the air conditioning case; and a face vent (in the passage of which an evaporator and a heater core are installed in that order), wherein the vehicle air conditioning device is characterized in that the face door is configured to doubly seal the defrost vent.

A heating, ventilation, and air conditioning (HVAC) apparatus for an automotive vehicle may include an internal volume divided into upper and lower regions, and configured for blowing the air to a defrost vent and a front seat face vent is made through the upper region, and blowing the air to a front seat foot vent and a rear seat vent is made through the lower region.

An HVAC system for a vehicle includes a housing, an evaporator disposed in the housing, and a heater disposed in the housing. The HVAC system further includes a bypass opening defined between an upper end of the evaporator and an upper end of the heater and an intermediate chamber defined by the evaporator, the heater, the housing, and the bypass opening. The HVAC system further includes an upper outlet passage configured to direct air from the HVAC system into a passenger compartment of a vehicle. The evaporator is configured to output a first stream of air into the intermediate chamber and the HVAC system is configured to operate in a first operating condition in which a first portion of the first stream of air will pass through the heater and a second portion of the first stream will bypass the heater by passing from the intermediate chamber through the bypass opening and into the upper outlet passage.

An air handling system for a vehicle comprises a conditioning section for controlling a temperature of a flow of air, a mixing section disposed downstream of the conditioning section with respect to a direction of the flow of the air, and a delivery section disposed downstream of the mixing section with respect to the direction of the flow of the air. The delivery section includes a first chamber, a second chamber, and a third chamber. A dividing plate separates each of the second chamber and the third chamber into a first side portion to a first side of the dividing plate and a second side portion to an opposing second side of the dividing plate. The second side portion of the third chamber is configured to primarily direct the flow of the air towards a rear seat area of the vehicle.

A vehicle may include an electric drive having at least one electric motor, at least one battery and at least one power electronic and may be cooled via a cooling circuit. The vehicle may include an air-conditioning system including at least one duct. A refrigeration circuit and a thermoelectric heating device may be arranged in the at least one duct. A control device may be configured/programmed to actuate the air-conditioning system, and may be operable to: activate the refrigeration circuit to cool the interior; operate the thermoelectric heating device as a cooler during a start-up phase of the refrigeration circuit; operate the thermoelectric heating device only as the cooler during the start-up phase of the refrigeration circuit when a cool-down function is activated; and automatically activate the cool-down function when a temperature difference between an actual temperature of the interior and a target temperature of the interior exceeds a predetermined temperature difference threshold value.
