A heat exchanger, preferably for a vehicle, including an applicative stratification, wherein the applicative stratification includes at least two stratification strands, wherein the applicative stratification is configured in such a manner that when incoming air into the heat exchanger is supplied in the direction of the applicative stratification, the incoming air is spread out by means of the applicative stratification in the respective stratification strand into an associated outgoing air portion. Furthermore, an exemplary embodiment may include an air-conditioning unit and an associated method.

A method for operating an air conditioning system, which may include a heating device, to condition air in a vehicle interior of a motor vehicle. At least one first air path and at least one second air path may each fluidically communicate with the air conditioning system and each open out into the vehicle interior. The method may include guiding the air from the vehicle interior via one of (i) the at least one first air path and (ii) the at least one second air path to the air conditioning system as a function of an operating state set in the air conditioning system. The method may also include guiding the air from the air conditioning system via the other of the one of (i) the at least one first air path and (ii) the at least one second air path into the vehicle interior.

An air flow device for a vehicle including an instrument panel dashboard, and a blower, the air flow device comprising a first outlet on a front upper surface portion of the instrument panel dashboard from which an air is sent along the front upper surface to a first inlet on the instrument panel dashboard into which the air blown from the first outlet is drawn; and a second outlet on a back upper surface portion of instrument panel dashboard from which an air is sent along the back upper surface to a second inlet on the instrument panel. The blower outlets are installed so as to open parallel to the blower inlets along an upper surface portion of the instrument panel dashboard.

A system for controlling movements of doors of an HVAC module includes an actuation gear and an intermediate cam. A main door includes a first portion and a second portion having a first guide. The first portion engages with actuation gear to enable linear movement of the main door. A slave door includes a second engagement element and moves between a blocking and unblocking position based on movement of main door. The intermediate cam moves angularly and includes a first engagement element and a second guide. The first engagement element interacts with the first guide, and the second guide interacts with second engagement element to facilitate angular movement of slave door in response to movement of the main door. The first guide includes a bend positioned to enable angular movement of the slave door after the main door moves a pre-determined distance.

A vehicular air conditioning device includes a blower, a heating heat exchanger, an auxiliary heater, and a blower controller. The heating heat exchanger heats blown air by exchanging heat between the blown air and the cooling water of the in-vehicle device emitting heat during operation. The blower controller is configured to control the operation of the blower. The blower controller is configured to increase a blowing capacity of the blower with increase of a temperature of the cooling water. The blower controller, during operation of the auxiliary heater, increases the blowing capacity after a waiting time during which the increase of the blowing capacity is prohibited has elapsed since a start-up switch of a vehicle system is turned on. The vehicular air conditioning is capable of implementing a quick warming of the in-vehicle device without impairing the heating feeling of occupant.

A temperature control equipment (3) for a vehicle, in particular an electric vehicle, enables an aerothermic adjustment of an airflow to be distributed in a passenger compartment (H) of the vehicle. The temperature control equipment (3) includes at least one heat treatment module (8), capable of heat-treating the airflow, and a distribution module (9), capable of distributing the airflow to the passenger compartment (H). The heat treatment module (8) comprises a single means (21) for heating the airflow to be distributed in the passenger compartment (H), which consists of an electric radiator (21).

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.

Comfortable vehicle interior air conditioning is realized while giving an appropriate temperature difference to air blown out from outlets. A vehicle air-conditioning device 1 includes an air mix damper 28, a FOOT outlet 29A, and a VENT outlet 29B. A control device has a B/L mode to blow out air from both of the FOOT outlet and the VENT outlet to a vehicle interior. In the B/L mode, the control device sets a target air volume ratio TGSW to be within a predetermined intermediate range of an air volume ratio SW by the air mix damper, and calculates a target heater temperature TCO on the basis of a target outlet temperature TAO and the target air volume ratio TGSW.
