− Co-authored by D. Oess, “Comfortable air conditioning for passenger cars (Mehr Klimako
mfort im Personenwagen) ", p. 4, Fig. 2)), the conditioned air is introduced by so-called reheat operation through a so-called central nozzle arranged on the dashboard in the central plane of the vehicle passenger compartment. . In the case of reheat operation, the sucked air is first cooled by the evaporator and thus dehumidified and then heated in the heat exchanger to the desired temperature. The amount of air introduced into the passenger compartment is regulated by a shut-off flapper valve at the air outlet opening of the central nozzle. The shut-off flapper valve restricts the air flow to a large amount or a small amount according to its opening. In the "maximum cooling" mode of operation, cold air is drawn out of the space behind the evaporator or in front of the heat exchanger via the cold air flapper valve, which is also called the draw-off flapper valve, and enters the passenger compartment via the air passage. be introduced. In heating operation, on the other hand, the outflow of air through the central nozzle is blocked either because the air is too cold (for design reasons) (below about 5 ° C) or very hot (above 40 ° C).

In the case of another air conditioner known in the above literature (see page 5 and FIG. 5), there is no warm air flapper valve, and the cold air flapper valve has the function of an air mixing flapper valve. The warm air flowing into the air passage through the opening is mixed with a large amount of cold air so as to obtain a desired air temperature. A shut-off flapper valve at the air outlet opening for the central nozzle adjusts the desired amount of air steplessly depending on the size of the throttle. In the case of this air conditioning installation, throttling of the mixed air at the air outflow opening to the central nozzle creates various pressure conditions in the air conditioning box, which cause a backflow, for example cold air being directed towards the rear of the heat exchanger. This can result in unwanted cold air flowing out of the air outlet openings to the defrost, side and foot nozzles behind the heat exchanger. This can only be avoided by means of supplementary non-return flapper valves at the cold and hot air openings.

[Advantages of the Invention] In the case of the air conditioning equipment according to the present invention, the principles of temperature adjustment by the air mixing flapper valve and flow rate adjustment by the shutoff flapper valve, which are used in general air conditioning equipment, are abandoned, and instead, each bypass opening is used. (Warm air opening and cold air opening)
Are individually squeezed. The flapper valve for the bypass opening is not followed by another shut-off flapper valve in the direction of air flow, so that in all operating modes there is only one flow towards the passenger compartment. The non-return flapper valve as in the known air conditioners mentioned above is not required. The regulating drive for the bypass flapper valve is continuously controlled.
A negative pressure element with a feedback potentiometer or a stepper motor is used as the adjusting drive.

The automobile air-conditioning installation shown in the schematic cross-section in FIG. 1 usually comprises a double-flow fan 10, an evaporator 11, a heat exchanger 12 and an air distributor 13. The above-mentioned components are arranged in a so-called air-conditioning box 14 in the above-mentioned order when viewed in the flow direction. The air-conditioning box 14 has an air distributor 13 projecting into the passenger compartment 20 of the traveling vehicle and has an air outflow opening (not shown). This air outflow opening allows air to flow into various portions of the passenger compartment 20 through the defrosting nozzle, the side surface nozzle, and the foot nozzle. A first suction opening 15, which is generally equipped with a filter, takes in fresh air into the air conditioning box 14 and the room air is sucked in from the passenger compartment 20 via the second suction opening 16. Both intake openings 15, 16 are alternately closed or opened by an air flapper valve 17. A separate air passage 18 extends above the air conditioning box 14 above the heat exchanger 12 and the air distributor 13 to the passenger compartment 20 where it opens into the air outlet opening 19. A central nozzle 21 that is integrally provided on the dashboard of the passenger compartment 20 is installed in the air outflow opening 19. The air passage 18 is connected to the space portion 141 of the air conditioning box 14 between the evaporator 11 and the heat exchanger 12 through the cold air opening 22, and is connected to the air distributor 13 through the warm air opening 23. . Each of the two bypass openings 22, 23 can be closed by a bypass flapper valve 24, 25. These bypass flapper valves 24, 25 can be driven steplessly by adjusting drive devices 26, 27. Both adjusting drives 26, 27 are connected to a control unit 28 whose input side is connected to setpoint transmitters 29, 30. One target value transmitter 29 is used to preset the air temperature of the air flowing into the passenger compartment 20 through the central nozzle 21, and the other target value transmitter 30 is used to preset the air amount. . The target value transmitters 29 and 30 are, for example, 0 to 5V
It is formed as a potentiometer with an adjustment range of.
In that case, the maximum air temperature or air amount corresponds to each upper limit value. The control unit 28 stores characteristics that give a relationship between the air amount and the air temperature of the air discharged from the central nozzle 21 and the opening degrees of the bypass flapper valves 24 and 25. In that case, the control unit 28 causes the regulating drive 26, 27 to bypass the flapper valve 2 for the air quantity and the air temperature preset by the setpoint transmitters 29, 30.
It operates to give a controlled variable that produces the opening given by the characteristic curves of 4, 25.

The second example of the characteristic curve stored in the control unit 28 is
It is shown diagrammatically in the figure. The characteristic curve indicated by the one-dot chain line for the hot air flapper valve 25 is given by UW = UM / Umax · UT (1), and the characteristic curve indicated by the solid line for the cold air flapper valve 24 is UK = UM-UW (2) Given in. In that case, UW and UK are control units
It is an adjustment voltage given to the adjustment drive devices 27 and 26 of the hot air flapper valve 25 and the cold air flapper valve 24 by 28. UT is an adjustment voltage within the adjustment range corresponding to the air temperature T preset by the target value transmitter 29. UM is the target value transmitter
Umax is a regulation voltage within the same regulation range corresponding to the air amount M preset at 30, and Umax is a bypass flapper valve 24, 25 at the fully open position where the entire cross-sectional areas of the cold air opening 22 and the warm air opening 23 are opened.

As a result, when the voltage UT = 4V, the control unit 28 controls the adjusting drive device 27 for the warm air flapper valve 25 to adjust voltage UW = 1.
Supplying 6V, adjusting drive device for cold air flapper valve 24
Supply the adjustment voltage UK = 0.4V to. Both regulation voltages are second
In the figure, two small circles are shown above the characteristic curves a and b. Hot air flapper valve 25 according to the adjustment amount UW, UK
Is opened somewhat smaller than the half air cross-sectional area of the warm air opening 23, and the cold air opening 24 narrows the cold air opening 22 very much. The total amount of air flowing through both bypass openings 22, 23 of the central nozzle 21 corresponds to the value given by the target value transmitter 30. For example, when the desired air temperature T is lowered by the target value transmitter 29 and the voltage is adjusted to UT = 2V, the adjustment voltage UW of the adjustment drive device 27 for the hot air flapper valve 25 is decreased to 0.8V, and the cold air is cooled. The regulation voltage UK of the regulation voltage 26 of the regulation drive device 26 of the flapper valve 24 rises to 1.2V. Correspondingly, the hot air opening 23 is throttled and the cold air opening 22 is further opened. When the target value transmitter 30 is not adjusted and is constant with respect to the desired air amount, that is, when UM = 2V, the central nozzle
The total amount of air, which consists of both air flows through the bypass openings 22 and 23 flowing into the passenger compartment 30 through 21, is constant.
