- the air box is preferably the air flap box of the motor vehicle. If two separate air duct systems are installed to the interior, this is a complex air duct system. If the lines of the air conditioner and the air heater merge into each other, both air currents are impaired in operation if both devices are operated at the same time. If only one device is operated, air conditioner or air heating, additional control or regulating flaps are usually necessary to prevent backflow into the non-operated device. In each operating case of the aforementioned operating cases, there are increased flow resistances, possibly even malfunctions.

- the essence of the invention is that the air conditioning duct and the heating air duct are brought together via an orifice in the form of a double nozzle which has an inner tube and a concentric outer tube.
- the double nozzle is constructed according to the jet nozzle principle (axial flow / suction effect) and / or swirl flow principle (circulation or swirl flow / suction effect).
- the double nozzle has a cylindrical inner tube and a coaxial cylindrical outer tube, the outlets each being conically tapered.
- the inner tube can be axially displaceable with respect to the outer tube, e.g. by an electric actuator, and can be determined within an adjustment range.

- the inner tube can have a coaxial face-side air inlet, which is opposite the conically tapered central outlet of the inner tube, and the outer tube has at least one jacket-side air inlet, which is opposite the conically tapered air outlet of the outer tube.
- the jacket-side air inlet is in particular a tangential air inlet for forming a swirl flow in the direction of the outlet.
- the jacket-side air inlet is a tangential swirl flow inlet with respect to the outlet of the outer tube and / or has a swirl flow guide device, wherein preferably the incline and / or the cross section of the swirl flow inlet and / or preferably the swirl flow guide device can be adjusted or are.
- a further swirl flow guiding device which is preferably adjustable, can be provided in the annular space between the inner pipe and outer pipe.
- the double nozzle can be followed by a coaxial cylindrical mixing tube with a tube-internal mixing device for the core and ring or swirl flow, which ensures a calming of the flow or turbulence reduction or reduction of the flow.
- the mixing device can comprise a mixing grid with radial guide surfaces.
- the double nozzle can be followed by a diffuser, which can be arranged upstream or downstream of the mixing tube which may be present.
- the outer tube preferably has two diametrically opposed jacket-side air inlets.
- the air inlet (s) on the opposite side can be connected to the air conditioning unit, while the air inlet on the front side is connected to the air heater.
- the preferably only jacket-side air inlet can be connected to the air heater, while the front air inlet is connected to the air conditioner.
- the air heater is preferably an auxiliary heater which can be operated independently of the engine or an auxiliary heater of a motor vehicle, in particular a commercial vehicle.
- the double nozzle can be arranged between an air flap box and a heat exchanger of a vehicle.
- the double nozzle is designed to be integrated in the air conditioning unit or is provided with the air conditioning unit as a structural unit, the air conditioning unit also being able to be integrated with the air flap case of a motor vehicle or arranged in the housing of the air flap box.
- the invention in particular connects the air heater to the vehicle air conditioning system for the parking and auxiliary heating operation via a simple mouthpiece in the form of a double nozzle, which is preferably operated according to the jet nozzle principle and / or swirl flow principle.
- the nozzle also acts as a check valve.
- the pressure-side connection of the air heater to the air conditioner for a standby and auxiliary heating operation takes place without mutual interference of the flow with low power consumption, low flow resistance and low noise emissions. No control elements or control flaps are necessary.
- the device according to the invention is particularly suitable for commercial vehicle air conditioning.
- the nozzle has a check valve function, in particular due to the swirl flow, which prevents backflow into the nozzle when air flow is applied to one side.
- the swirl flow is supported by a tangential inflow into the outer nozzle.
- the swirl flow can be adjusted through the inlet cross section into the outer nozzle, which prevents backflow. This means that no additional non-return and control flaps are required.
- the swirl flow creates a negative pressure and supports the core flow of the inner nozzle while the air conditioning unit and the air heating unit act on the nozzle.
- the inner nozzle can be designed to be displaceable with the core flow.
- the outer nozzle can be followed by a mixing device with a mixing grille and / or a diffuser for delaying the air flow.
- the so-called 3D nozzle according to the invention can also be part of the air conditioner in the area between the heat exchanger and flap box.
- the functional principle of the nozzle can be integrated in the air conditioner by clever arrangement or inflow of the heating air and by means of a swirl flow generated. The exact overall arrangement is often determined by experiment.
- the air volume of an air conditioning system is approximately six times the air volume of the heating air of the auxiliary or auxiliary heater of a commercial vehicle.
- the air-conditioning air is preferably fed to the outer annular space of the double nozzle via two diametrically offset air inlets and the heating air from the auxiliary or auxiliary zers centrally introduced into the inner tube of the double nozzle as a core flow.
- more than two jacket-side air conditioning inlets can also be provided on the jacket circumference of the outer tube of the double nozzle.
