An vehicle air conditioner (1A) includes a duct (3) in which a partition member (4) forming a first flow path (3A) and a second flow path (3B) is provided, and a heat pump circuit (2A). In the heat pump circuit (2A), a first indoor heat exchanger (12A) that contributes mainly to heating is located in the first flow path (3A) or faces an outlet of the first flow path (3A), and a second indoor heat exchanger (12B) that contributes mainly to cooling is located in the second flow path (3B). The ratio between an internal air and an external air within air flowing through each of the first flow path (3A) and the second flow path (3B) is adjustable. The duct (3) is provided with at least one of a heating exhaust port (35) for discharging air cooled in the second indoor heat exchanger (12B) to the outside of the vehicle interior in heating operation, and a cooling exhaust port (36) for discharging air heated in the first indoor heat exchanger (12A) to the outside of the vehicle interior in cooling operation. This configuration enables the air within the vehicle interior, the temperature of which has been adjusted by heating or cooling, to be efficiently utilized without wasting energy by discharging the air as it is to the outside.

A vehicle air conditioner includes a first passage and a second passage and is capable of operating in such a manner that outside air introduced in the first passage is conditioned by an evaporator and a heater core and subsequently blown, as a conditioned air, from a defrost outlet, side defrost outlet and side vent outlet toward windowpanes and, at the same time, inside air introduced in the second passage is conditioned by the evaporator and the heater core and subsequently blown, as a conditioned air, from a center vent outlet and front and rear heat outlets into a passenger compartment.

The present disclosure describes an air conditioning apparatus comprising an air conditioning case defining an airflow passage, an evaporator accommodated in the air conditioning case, a first blower located at an upstream side of the evaporator creating a first airflow in the airflow passage, a second blower located at an upstream side of the evaporator creating a second airflow in the airflow passage, and a controller electrically connected to the first blower and the second blower. The controller controls the first blower and the second blower based on a target total airflow amount. The first airflow and the second airflow are mixed at the upstream side of the evaporator. The air conditioning apparatus further comprises means for preventing the first airflow from being directed into the second blower.

An air flow device for an instrument panel which blows an air from the instrument panel at a front of a vehicle compartment of an automobile to make the air flow to the vehicle compartment, includes a blower, a blower outlet on the instrument panel, from which an air sent from the blower to which the blower outlet is coupled is blown to the vehicle compartment, and a blower inlet on the instrument panel for the blower outlet, into which the air blown from the blower outlet is drawn. The blower outlet is installed so as to open to the blower inlet along a surface of the instrument panel while the blower inlet is installed so as to open to the blower outlet along the surface of the instrument panel.

An HVAC device including a compressor and a first blower disposed along ventilation pipes for taking in interior air of the vehicle through a duct in communication with the first blower. An evaporator and dehumidifying member may be disposed along the ventilation pipes and in communication with the first blower. The device includes a condenser and an electrical heating unit disposed along the ventilation pipes and in communication with the first blower, and a vehicle interior air reflux duct disposed along the ventilation pipes and in communication with first blower and the interior of the vehicle. A second blower disposed along the ventilation pipes for taking in air outside of the vehicle through another duct, and a first exhaust duct and a second exhaust duct disposed along the ventilation pipes and in communication with the second blower. The device includes several modes for creating different flow paths through the vehicle.

Disclosed is an air conditioning system for a vehicle which includes a cold air passageway having a heat exchanger for cooling and a warm air passageway having a heat exchanger for heating inside an air-conditioning case to carry out cooling and heating and which controls to inhale indoor air inside the vehicle, pass the air through the heat exchanger for cooling and discharge the air outside the vehicle in a specific mode, thereby preventing frosting of the heat exchanger for cooling because supplying air of high temperature dehumidified inside the interior of the vehicle to the heat exchanger for cooling, and enhancing heating performance by rising refrigerant pressure and temperature in the refrigerant cycle without needing additional components.

A climate control system of a vehicle includes an evaporator, a first blower, and a first blower passageway that receives air blown from the first blower. The system also includes a second blower and a second blower passageway that receives air blown from the second blower and that is fluidly independent of the first blower passageway. The system further includes a ducting assembly defining a common passageway that receives air from both the first and second blower passageways. The first and second blowers are configured to operate in parallel to deliver air to the common passage and across the evaporator.

A system for mixing air for a vehicle HVAC (heating, ventilation, air-conditioning) component, includes a first inlet for outdoor air from an exterior space of the vehicle; a first fan in communication with the first inlet to control (only) an air inflow through the first inlet; a second inlet for indoor air from an interior space of the vehicle; and a second fan in communication with the second inlet to control (only) an air inflow through the second inlet. The first fan and the second fan are independently controllable to provide a desired mix of air to the vehicle HVAC component.
