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 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.

The present invention relates to an air conditioner for a vehicle, which can remarkably improve resistance against an air flow in an air passageway, thereby enhancing efficiency. The air conditioner for a vehicle includes: a case having an air inlet, an air outlet, and an air passageway formed therein; a blower unit for blowing air to the air inlet; and a cooling means and a heating means disposed in the air passageway of the case in an air flow direction in order, wherein the air outlet of the case includes a floor outlet and vent outlets, the floor outlet and the vent outlets are arranged below the heating means in a height direction, and the floor outlet is arranged within a range of the width of the heating means.

Climate control device for motor vehicle conveys and conditions inflowing air for a passenger compartment includes a housing with a diffuser, a mixing zone and at least two flow paths through which two flows can be conducted in parallel. A heating heat exchanger is disposed in a first flow path to heat an air mass subflow. A heat exchanger is provided for cooling and/or dehumidifying inflowing air. A bypass flow path is provided through which air can flow in parallel to a flow channel with the heat exchanger. At least one flow guide mechanism opens and closes the bypass flow path. flow channel and bypass flow path open out with outlet ports into mixing zone. Outlet port of a bypass flow path is developed for specific discharge of an air mass subflow into first flow path in proximity of an opening site of first flow path into a mixing zone.

A vehicle air conditioning apparatus includes an air conditioning case including a case body having a case opening that is open to an air conditioning opening, and a case cover that can open and close the case opening. The case cover can be attached/detached to/from the case body via the air conditioning opening outside of the vehicle interior. An evaporator and a heater can be attached/detached to/from the case body via the air conditioning opening outside of the vehicle interior, while the case cover is removed from the case body to open the case opening.

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.

An air conditioner for a vehicle capable of preventing a situation in which an occupant's head gets hot by improving a vertical temperature difference between a defrost vent and a floor vent, includes an air conditioning case in which an air flow path is formed, and a cooling heat exchanger and a heating heat exchanger provided sequentially on the air flow path of the air conditioning case in an airflow direction, wherein a defrost vent, a face vent, and a floor vent are formed on the air conditioning case, wherein a hot air duct configured to allow hot air at a downstream side of the heating heat exchanger to flow to an outlet of the floor vent is provided on the air conditioning case.

An arrangement for the air distribution of an air conditioning system (1) of a motor vehicle. The air conditioning system (1) is configured with a housing (2) with at least two flow paths (6, 7), which empty into a mixing chamber (8), and at least one air outlet (3a, 3b, 3c) as well as an air flap (10, 11, 12) which can open and close the at least one air outlet (3a, 3b, 3c). The arrangement has a device (18) for air mixing with at least one air resistance element (21), which is supported so that it can turn about an axis of rotation (20) and which extends in the direction of the axis of rotation (20). The air resistance element (21) is configured with at least one flow through opening, so that depending on the position of the device (18) a cross section of at least one flow path (6, 7) of the housing (2) can be changed.

An air-conditioning unit of a motor vehicle may include a fan, an evaporator, and a heat exchanger. The heat exchanger may be arranged downstream of the evaporator. The evaporator and heat exchanger may both be arranged in a housing. The air-conditioning unit may also include a first bypass channel bypassing the evaporator. The first bypass channel may be arranged centrally on a side of the evaporator. A width of the first bypass channel may be smaller than a width of the side of the evaporator on which the first bypass channel is arranged.

Certain disclosed embodiments pertain to controlling temperature in a passenger compartment of a vehicle. For example, a temperature control system (TCS) can include an air channel configured to deliver airflow to the passenger compartment of the vehicle. The TCS can include a one thermal energy source and a heat transfer device connected to the air channel. A first fluid circuit can circulate coolant to the thermal energy source and a thermoelectric device (TED). A second fluid circuit can circulate coolant to the TED and the heat transfer device. A bypass circuit can connect the thermal energy source to the heat transfer device. An actuator can cause coolant to circulate selectively in either the bypass circuit or the first fluid circuit and the second fluid circuit. A control device can operate the actuator when it is determined that the thermal energy source is ready to provide heat to the airflow.
