Description

MULTI-ZONE AIR CONDITIONING INSTALLATION, AND MOTOR

VEHICLE

The invention relates to an air conditioning installation for a vehicle, having an air conditioning mixing zone, a heat exchanger, and a device for the preferred feed of air, depending on requirements, to the predetermined air conditioning mixing zone. The air conditioning installation has a first control flap by means of which a first partial volumetric flow can be directed by way of the heat exchanger to the air conditioning mixing zone, and a second control flap by means of which a second partial volumetric flow can be directed by way of a bypass duct, past the heat exchanger, to the air conditioning mixing zone. The air conditioning installation herein is in particular also conceived for a multi-zone air conditioning. The invention furthermore relates to a motor vehicle having such an air conditioning installation.

A heating, ventilation, and/or air-conditioning of a vehicle is referred to as an air conditioning installation for a vehicle in the context of the invention. The vehicle herein is preferably a motor vehicle, such as a passenger motor vehicle or a commercial vehicle.

Air-conditioning installations are intended to reliably provide a comfortable climatic environment in the interiors of the most varied vehicle types. This should be the case both in the front region as well as in the rear region of a vehicle, likewise in a respective foot region and in the seating region of the vehicle occupants, said regions hereunder also referred to as ventilation regions.

For this reason, known air conditioning installations have different air conditioning mixing zones for the front and for the rear region, that is to say for the region of the front seats and of the rear seats of a vehicle, and for various zones in those regions.

The air conditioning of the rear region herein is controlled by a separate mixing flap, one or a plurality of distributing flaps for distributing the air between the foot region and the ventilation region typically being downstream of said mixing flap. "Downstream" in the context of the present invention means that an element in the flow direction of the air is located at a downstream side of the respective reference component. In the case of a maximum demand for air, in particular a demand for hot air, for example for defrosting a windscreen, it is known for the various flaps of the air conditioning installation to be set such that an air volume that is as large as possible is directed to the windscreen. In this state, the rear-region air conditioning mixing zone is not at all supplied with air or only to a minor degree.

Known air-conditioning installations furthermore have a device for providing an airflow at a desired temperature in a ventilation region. An air conditioning installation which for this purpose has two control flaps is shown in DE 10 2014 109 925 A1 . A heated airflow can be directed by one of the control flaps into the air conditioning mixing zone, and a cold airflow can be directed by the other control flap into the air conditioning mixing zone, wherein depending on the temperature desired the volumetric airflow of the heated and of the cold airflow are set accordingly by way of the control flaps.

The effect known as the "volumetric cold air influence" in which the temperature of the airflow that is dispensed in a specific ventilation region by the air conditioning installation does not correlate in a linear manner to the set temperature is an undesirable effect of these devices. This effect arises above all in the case of external temperatures below 4°C and is caused by the temperature of the cold airflow that is supplied to the climate mixing zone corresponding approximately to the external temperature and therefore cooling to a variable degree the heated airflow that is supplied to the climate mixing zone. This nonlinear behaviour of the dispensed temperature can also not be remedied by way of a fine setting of the control flap which directs the cold airflow into the air conditioning mixing zone. It is therefore an object of the invention to provide an improved air conditioning installation which enables in particular by way of a minor effort an airflow, the temperature of which follows the set temperature in a linear manner even under various operating conditions, to be dispensed.

This is enabled by an air conditioning installation according to Claim 1 of the present invention. Advantageous refinements are the subject matter of the dependent claims. A multi-zone air conditioning installation, according to the invention, for a vehicle includes at least one heat exchanger by way of which air can be directed through so as to temperature-control said air which subsequently can be directed to a first region and/or to a second region of a motor vehicle, and at least one first and one second control flap by way of which a proportion of an overall volumetric airflow and the temperature of the latter can be set, said proportion being supplied to an air conditioning mixing zone having an air outflow duct, wherein the first control flap in a controlled manner can release a bypass duct by way of which air can be directed past the heat exchanger to the air conditioning mixing zone, wherein a bypass flap which can throttle the volumetric airflow in the bypass duct is provided in the bypass duct. "Past the heat exchanger" herein means that the air is substantially not heated by the heat exchanger but makes its way directly by way of the bypass duct into the air conditioning mixing zone. The volumetric airflow that is not heated by the heat exchanger, that is to say the cold volumetric airflow, supplied to the air conditioning mixing zone can be set by means of the bypass flap additionally to the first control flap. On account thereof, the temperature of the air in the air conditioning mixing zone is able to be regulated in such a manner that the air that is dispensed by way of the air outflow duct has a temperature which follows the set temperature in a linear manner, even under various operating conditions. The operating conditions comprise in particular different external temperatures.

A throttle flap for varying the flow cross-section can be provided in an air outflow duct of the air conditioning mixing zone, said throttle flap being neutral in terms of temperature and controllable in an independent manner. "Neutral in terms of temperature and independent" herein means that the throttle flap can be actuated without the actuating flaps and consequently also the temperature of the air volume in the air conditioning mixing zone having to be modified. The throttle flap can thus be actuated without any change arising in the temperature of the volumetric flow that is supplied to the second region. The temperature and the temperature distribution of the air volume immediately prior to passing through the throttle flap and immediately after passing through the throttle flap thus remain identical. A temperature-maintaining reduction of the volumetric flow is enabled in this way. The throttle flap in the context of the invention is therefore referred to as „neutral in terms of temperature", wherein this term is to be understood to be the above-mentioned effect of the throttle flap by virtue of this specific configuration and disposal thereof in the air conditioning installation.

In some refinements of the invention, the air conditioning installation can comprise a second control flap which can direct the heated air either to the first region, thus to an air conditioning mixing zone and further to a predetermined vehicle region, or to a further air conditioning mixing zone and further to a second vehicle region, or in the case of intermediate positions can split said heated air between the first region and the second region. The air supply to the various regions of the vehicle can thus be performed so as to depend on requirements. In particular, in the case of a requirement of rapid defrosting, a maximum volume of pre-heated air can be directed to a front region of the vehicle, specifically to a windscreen to be defrosted, by virtue of a corresponding position of the control flaps.

In one special embodiment, the air conditioning installation for a vehicle has a first air conditioning mixing zone and a second air conditioning mixing zone. The second air conditioning mixing zone includes a first air inflow duct and a second air inflow duct. Furthermore, the air conditioning installation has at least one mixing flap which is disposed between the first and the second air inflow duct, said mixing flap being able to control an air supply to the first and/or to the second air flow duct. This means that the mixing flap, also referred to as the first control flap, can adjust an air supply both into the first air inflow duct as well as into the second air inflow duct in a range between 0% and 100% of the potential air volume in flow. Each of the two air inflow ducts can thus also be completely closed by the mixing flap. A heating device for heating the air flowing through the second air inflow duct can in particular be disposed in the second air inflow duct. The air from the air conditioning mixing zones is then directed into the desired vehicle regions, thus for example the rear or the front, the foot region or the ventilation region, or further envisaged zones.

In one alternative embodiment, the air conditioning installation can comprise one or a plurality of air conditioning mixing zones. At least one of these air conditioning mixing zones herein is configured as a second air conditioning mixing zone, having the corresponding features. A main flap which can control an air supply to the first air conditioning mixing zone and/or to the second air conditioning mixing zone is disposed herein on a downstream side of the second air inflow duct. The second control flap, or else the main flap, is configured so as to be able to completely prevent the air supply from the second air inflow duct to the second air conditioning mixing zone, for example in the case of a defrosting operation, and to instead direct the air to the first air conditioning mixing zone.

The first and the second control flap can be controlled by a common first kinematics. A simplified actuation of the flaps according to requirements can be enabled in this way. This coupling can be performed, for example, by way of a link-type guide and an associated link disc.

In some embodiments of the invention, the first control flap, the mixing flap, the second control flap, thus the main flap, and the throttle flap of the air conditioning installation are controlled by a common kinematics. The kinematics for adjusting the flaps, in particular for adjusting the throttle flap, herein is in some embodiments the kinematics for controlling the rear ventilation region, also referred to as the third zone. A reliable air conditioning of the rear of the vehicle, in particular of the rear ventilation region, that is independent of the ventilation of other vehicle regions such as the front region, can be enabled in this way. Of course, it is also possible for the throttle flap to be controlled collectively with the kinematics of the mixing flap or of the main flap, wherein the flap that is not included in the kinematics can be controlled in a manner independently thereof.

In preferred refinements of the invention, the heat exchanger is configured as a heating device. A control flap, in particular the second control flap (if provided), herein is downstream of the heating device. A determinable quantity of the hot air generated can be directed through this control flap into the air conditioning mixing zone and be mixed with cold air in the latter. A temperature for the vehicle interior can be set in this manner.

Moreover, an air outflow duct that leads away from the second air conditioning mixing zone can additionally be configured with at least one throttle flap. On account thereof, the flow cross-section of the air that flows away from the second air conditioning mixing zone can be varied in at least one part of the air outflow duct. The air can thus be directed to the desired rear vehicle regions, in particular to a foot region and/or to a ventilation region.

A volumetric flow of air in the air outflow duct can be set in a simple manner by providing a throttle flap of this type. This setting can be readily performed for the ventilation systems of the most varied vehicle types. The air conditioning installation according to the invention is thus usable in various vehicle types. A universal application of the air conditioning installation can thus take place, this reducing the complexity in the case of a design and construction that is vehicle- dependent. The production costs can also be reduced by virtue of the potential standard construction of the air conditioning installation.

In this way, the air conditioning for the rear region can be corrected in the case of a potential use of a booster in some operational states. In general, the air conditioning installation according to the invention permits an improved and more comfortable control of the overall airflow in the rear region than is possible in the case of the cooling, heating, and air-conditioning systems known to date. In particular, a setting of a supplied climate zone can be carried out independent of other climate zones, in particular vehicle regions.

In some embodiments of the invention, the air conditioning installation is configured such that the air outflow duct has at least one first air outlet duct and at least one second air outlet duct, each being disposed downstream of the throttle flap. The airflow that is to be directed through the air outflow duct to the various regions of a vehicle interior, and consequently also the flow pressure can thus be controlled or regulated by way of the throttle flap. The air conditioning zones of the vehicle can be controlled in this way in a manner that is more comfortable for the passengers. Moreover, the airflow from the second air conditioning mixing zone can be controlled in a manner independent of the airflow and of the flap control of the first air conditioning mixing zone. This enables in particular a four-zone air conditioning of a vehicle region, in particular of the vehicle rear. In some alternative embodiments, the air conditioning installation for a vehicle is configured such that the air outflow duct has at least one first air outflow duct and at least one second air outflow duct, wherein the throttle flap is configured in at least one of the air outflow ducts. In particular, the throttle flap can be configured in one or a plurality of air outflow ducts which direct an airflow to the ventilation region of the rear of the vehicle. This permits a four-zone air conditioning, or else a three-zone air conditioning, of a vehicle region, in particular of the vehicle rear. Moreover, the provision of the throttle flap in an air outlet duct can cause improved regulating of the airflow and of the air pressure in the air outlet duct.

In some refinements, the throttle flap is upstream of the air outlet ducts. Apart from controlling the airflow and the air volume in one or in all air outlet ducts by the throttle flap, a precise setting of the air supply can be performed so as to depend on requirements. This can enable an improved air conditioning by the air conditioning installation.

The bypass flap can be controlled by a second kinematics. The second kinematics herein is controllable in an independent manner, in particular independently of the first kinematics. This means that the bypass flap can be controlled without any of the remaining flaps, in particular any of the actuating flaps for the air supply, having to be adjusted. In this way, the cold volumetric airflow in the bypass duct is able to be throttled in a manner independent of the first control flap, on account of which the temperature of the air in the air conditioning mixing zone is able to be regulated in such a manner that the air that is dispensed by way of the air outflow duct has a temperature which follows the set temperature in a linear manner even under various operating conditions.

The flow cross-section of the bypass flap can be varied in a range between 0% and 100% of the flowing air. This setting can be performed in a stepless or step-by-step manner. The throttle flap can be controllable in an independent manner by a third kinematics. This means that the throttle flap can be controlled without any of the remaining flaps, in particular any of the actuating flaps for the air supply, having to be adjusted. The control can also be adjusted independently of any potential flaps that are disposed downstream, as will yet be illustrated in more detail hereunder. The flow cross-section herein can be varied by the throttle flap in a range between 0% and 100% of the flowing air. This setting can be performed in a stepless or step-by-step manner.

It is enabled in particular in this way for a controlling of the volumetric flow that is to be supplied to a specific, presently a second, vehicle region to be controlled independently of the volumetric flows that are to be supplied to other regions, in particular to a first vehicle region. An air-conditioning that is more comfortable for the passengers of the vehicle and is able to be set in an improved manner can thus be achieved. In some refinements, the bypass flap is functionally coupled to a temperature sensor so as to be controlled independently of the temperature of the air that flows through the air inflow duct. On account thereof, a temperature profile in the vehicle region can be provided independently of the temperature of the air flowing in through the air inflow duct, said temperature being caused by the external temperature, for example, said temperature profile correlating to the set temperature in a linear manner. Furthermore, temperature variations in the inflowing air can be equalized by a corresponding position of the bypass flap.

In some embodiments, an evaporator which is configured for conditioning air that flows through an air supply region is disposed upstream of the heat exchanger. "Conditioning" in the context of the invention means in particular a change in the air humidity and/or the temperature. In this way, cooled air in a vehicle region can also be provided when the inflowing air is warmer than the set internal temperature in the vehicle, for example when the inflowing air contains air from the environment of the vehicle and the external temperature is correspondingly high.

In specific embodiments, the temperature sensor is disposed downstream in relation to the evaporator. The temperature of the air flowing through is thus measured after any potential conditioning by the evaporator. On account thereof, the temperature of the airflow in the bypass duct can be determined more accurately and the control of the bypass flap can be improved so as to guarantee a specific temperature in the air conditioning mixing zone. The bypass flap is preferably disposed downstream of the first control flap. This has the advantage that the volumetric airflow in the bypass duct, that in a first step is set by the first control flap, can be throttled in a subsequent second step by the bypass flap. This fine adjustment of the cold volumetric airflow that is supplied to the air conditioning mixing zone by the bypass flap enables an improved control of the mixing ratio of the heated and of the cold volumetric airflow in the air conditioning mixing zone.

The bypass flap can be a single-wing flap or a double-wing flap.

A further aspect of the invention relates to a vehicle having an air conditioning installation according to the invention.

The invention will be described hereunder by means of the appended drawings in which:

Fig. 1 shows an air conditioning installation according to the invention in a schematic sectional illustration, wherein the air conditioning installation is shown in a first position; and

Fig. 2 shows the air conditioning installation of Fig. 1 in a second position.

An air conditioning installation 1 which is provided in particular for the installation in a motor vehicle is shown in Fig. 1 . The air conditioning installation 1 has an air inflow region 19 which downstream transitions into a cold-air inflow region 2. The air conditioning installation 1 furthermore has a first air conditioning mixing zone 4 and a second air conditioning mixing zone 6.

An airflow in the form of an overall volumetric airflow flows by way of the air inflow region 19 into the cold-air inflow region 2.

A blower 17 which blows the overall volumetric flow into the air inflow region 19 can be provided in or outside the air conditioning installation 1 .

An evaporator 15 which is configured for conditioning the air that flows through the air inflow region 19 is disposed in the air inflow region 19. "Conditioning" in the context of the invention means that in particular a change in the air humidity and/or the temperature is performed. A first flap 3 is disposed along a first flow duct between the first air conditioning mixing zone 4 and the cold-air inflow region 2. Moreover, a heating flap 5, followed by a heating installation (heat exchanger 7) is provided along a second flow duct between the first air conditioning mixing zone 4 and the cold-air inflow region 2. Air can thus make its way to the first air conditioning mixing zone 4 either through the flap 3 or through the flap 5 and the heating device 7. By controlling the opening of the flaps 3 and 5, a pre— definable mixing ratio of cold air and air that is heated in the heating device 7 can thus be set for the air conditioning mixing zone 4. The solid line of the flap 3 in fig. 1 identifies the closed position of the flap 3, while the dashed line identifies the opened state of the flap 3. In the case of the heating flap 5, the solid line identifies the opened state, while the dashed line identifies the closed state.

A first control flap 8, hereunder referred to as the mixing flap, is provided along a first air inflow duct 8a between the cold-air inflow region 2 and the second air conditioning mixing zone 6. The mixing flap 8 is configured in such a manner that the bypass duct 8a can be completely closed. This is illustrated in fig. 1 by the bold illustration of the flap 8.

A heating device which in the embodiment shown represents part of the heating device 7 already described is provided along a second air inflow duct 8b between the cold-air inflow region 2 and the second air conditioning mixing zone 6. The heating device in the air inflow duct 8b to the second air conditioning mixing zone 6 can however also be a separate heating device.

A second control flap 10, hereunder referred to as the main flap, is disposed downstream of the heating device 7. The main flap 10 is configured in such a manner that a connection between the second air inflow duct 8b and the second air conditioning mixing zone 6 can be closed. At the same time, the main flap 10 can open a connection of the second air inflow duct 8b to the first air conditioning mixing zone 4. All air that has entered through the heating device, depending on requirements, can thus be directed either through the second air inflow duct 8b or through the heating flap 5 to the first air conditioning mixing zone 4. This is necessary, for example, in the case of a so-called defrosting operation for rapid defrosting of the windscreen. The main flap 10 is configured as a double-wing flap which closes the connection to the second air conditioning mixing zone 6 when a connection to the first air conditioning mixing zone 4 is opened, and vice versa. The bold illustration of the main flap 10 in Fig. 1 represents a position in which the connection to the first air conditioning mixing zone 4 is open to the maximum, and a connection to the second air conditioning mixing zone 6 is closed. However, the main flap 10 can also assume any arbitrary positions lying therebetween.

The mixing flap 8 is configured in such a manner between the air inflow ducts 8a and 8b that said mixing flap 8 can selectively close one of the air inflow ducts 8a, 8b, or assume any arbitrary intermediate position such that a pre- determinable ratio of airflow flows through the air inflow ducts 8a, 8b. It is controlled in this way which proportion of the airflow is to be heated in the heating device 7 and which proportion is to be directed through the bypass duct 8a, past the heating device. A desired temperature-controlling of the air can thus be performed in the second air conditioning mixing zone 6.

The mixing flap 8 and the main flap 10 are controllable by means of a common first kinematics.

A bypass flap 12 which by way of a second kinematics is controllable in an independent manner, in particular independently of the control flaps 8, 10, is located downstream of the first control flap 8 in the bypass duct 8a. The bypass flap 12 is a double-wing flap. The bypass flap 12 can be provided as a single- wing flap in an alternative embodiment.

The bold illustration in Fig. 1 identifies the closed position of the bypass flap 12, while the dashed illustration identifies an opened position of the bypass flap 12.

The air conditioning installation 1 , downstream of the evaporator 15, has a temperature sensor 18 which is functionally coupled to the bypass flap 12 such that the bypass flap 12 can be controlled so as to depend on the temperature of the air flowing through the bypass duct 8a. In this way, the cold volumetric airflow in the bypass 8a can be throttled by means of the bypass flap 12 so as to reduce the proportion of the cold volumetric airflow which flows into the second air conditioning mixing zone 6. Alternatively, the temperature sensor 18 can be disposed upstream of the evaporator 15. In this case, the influence of the evaporator 15 on the temperature of the airflow can be conjointly considered in the controlling of the bypass flap 12, so as to be able to equalize deviations of the measured temperature from the actual temperature of the cold airflow after the evaporator 15.

In an alternative embodiment, the temperature sensor 18 can be provided in or on the motor vehicle, wherein said temperature sensor 18 can measure the external air temperature.

An air outflow duct 16 leads away from the second air conditioning mixing zone 6. Said air outflow duct 16 directs the air to a vehicle region (not illustrated), for example to the rear region of the vehicle. The air outflow duct 16 in the embodiment shown in Fig. 1 has two air outlet ducts 1 1 a, 1 1 b. The air outlet ducts 1 1 a, 1 1 b serve for directing the air to different regions of an air conditioning zone. In an exemplary but not limiting manner, the air outlet duct 1 1 a can direct the air to a vehicle rear ventilation region, and the air outlet duct 1 1 b can direct the air to a vehicle rear foot region.

A throttle flap 14 is moreover provided in the air outflow duct 16, so as to be upstream of the air outlet ducts 1 1 a, 1 1 b. The throttle flap 14 is controllable by a third kinematics and is configured in such a manner that said throttle flap 14 can control or regulate the air volume that flows through the air outflow duct 16. The throttle flap 14 thus permits a ratio of the air distribution between different air outflow ducts of the air conditioning installation to be able to be set without any complicated readjustment by means of the mixing flap 8 and/or of the main flap 10 being necessary. Consequently, the setting of the volumetric flow can be performed independently of the other air conditioning zones of the vehicle

The bold illustration of the throttle flap 14 in Fig. 1 illustrates an opened position. The throttle flap 14 can also be completely closed, as is indicated by the dashed line. Moreover, the throttle flap 14 can assume any arbitrary intermediate position between the closed state and the opened state. The reference signs introduced for Fig. 1 will continue to be used hereunder for the same or similar components, the description of which will not be repeated. Only points of differentiation between the illustrations are to be discussed hereunder.

Fig. 2 shows the air conditioning installation 1 from Fig. 1 , wherein only the second control flap 10 is completely closed. The first control flap 8 is in a slightly open position so that a comparatively small proportion of air can flow through the bypass duct 8a into the air conditioning mixing zone 6. The remaining proportion of the air to be conditioned, after passing the evaporator 15, can flow both directly into the first air conditioning mixing zone 4 by way of the open flap 3, as well as by way of the open flap 5 and the heat exchanger 7. The arrows in Fig. 2 illustrate the various paths of the flowing air in the air conditioning installation 1 .

Since the air is directed into both air conditioning mixing zones 4, 6, both the front region as well as the rear region in this example are supplied with conditioned air.

In the operation of the air conditioning installation 1 , the cold volumetric airflow which flows into the air conditioning mixing zone 6 is regulated by means of the bypass flap 12 additionally to the first control flap 8. In that the bypass flap 12 throttles the cold airflow so as to depend on the temperature of the latter, the temperature of the air in the air conditioning mixing zone 6 can be regulated in such a manner, that the air that is dispensed by way of the air outflow duct 16 has a temperature which follows the temperature set by a user in a linear manner. This linear temperature profile can be guaranteed even at various operating conditions such as, for example, external temperatures of below 0°C or a varying temperature of the air flowing into the air conditioning installation 1 .
