Description

The The invention relates to a control and regulating device and an operating method for ozone emitter having the features in the preamble of the main claim.

A controller for ozone emitter with dielectrically impeded discharge is from the WO 03/080507 A1 known. Here, the ozone production rate of the ozone emitter is determined by counting the current pulses or radiation flashes that occur in the so-called plasma needles or filaments in an ozone emitter designed as a planar module. Based on the counting results of the ozone emitter acting high voltage generator is controlled.

The DE 100 13 841 A1 shows another control and regulating device for ozone emitter with dielectrically impeded discharge, in which the secondary side connected to the high voltage generator ozone emitter, a voltage divider is connected, with a typical for the ionization signal, namely a high-frequency filament signal, tapped and passed through a control voltage generator, wherein After this signal in conjunction with an air quality sensor, the ionization power is controlled.

It The object of the present invention is to provide an improved and control technology.

The Invention solves this problem with the features in the main claim.

The claimed control and regulating device controls and regulates the High-voltage generator according to the current at the ozone emitter current or possibly after the performance. About the preferably primary-side Recording and evaluation of the recorded operating current and / or the electrical operating power of the high voltage generator and the ozone emitter are controlled to one operating point. The Operating current measurement sets with relation to the operating voltage Absolutwertbestimmung. It will be the absolute operating current and / or recorded the absolute operating performance. This has the advantage that an operating point with absolute position in relation to a current or Performance map can be determined. On a relative value determination, in particular to a direct determination of the filament streams or the individual Filamententladungen can optionally be waived become. For the execution of the regulation there is no unconditional Need for a decoupling element, a downstream Filter or signal conditioning. These elements can therefore omitted.

The Regulation assumes that the function of the ozone emitter and the ozone production with the power and power consumption of the high voltage generator correlated. This control technology and the for this used hardware require a small and inexpensive Expenditure, largely used existing components anyway can be.

at The operating current measurement can be all factors, such as the Load the transformer by high-frequency filament formation and by additional reactive current, possibly taking into account the Internal resistance (losses) of the voltage source, and the efficiency of the transformer are detected.

The claimed control technology also allows a detection of special operating conditions of the ozone emitter, in particular deposits on the emitter, its functional behavior impair, can be detected. The Detection can be based on the absolute value of the operating point respectively. The control technology and the claimed operating method also offer the possibility of such deposits quickly to eliminate and restore the normal operating behavior of the ozone emitter. For this, the normal operation can be controlled by a temporary Control of high voltage and possibly the operating current superimposed or replaced, which is a detachment of the deposits, especially an evaporation of liquids allowed. After removing the deposits can return to normal Operating condition and the normal control behavior are recorded.

The Operational impairments and in particular the deposits can be of different nature. The deposits can be electrically conductive or insulating and z. B. from code water, dust or electrically conductive media, eg. Salt water, consist. By means of a detection device can both the existence, as well as the characteristics of such impairments and in particular deposits are detected. With the tax and control technology are then appropriate targeted responses and possibly removal measures possible.

The regulation or control over the recorded operating current and / or the operating power can be supplemented or replaced by a control or regulation by means of detection of the filament signals generated by the ozone emitter. There are several possibilities for this. On the one hand, the previously known pulse count can be used. On the other hand, a capacitance can be charged with the filament pulses, their charge behavior being detected and evaluated in relation to time becomes. This is a variant with an independent inventive meaning, which is also in another control and regulation, z. B. according to the above-mentioned prior art instead of the voltage divider or the like. Can be used.

The claimed control technology is for different Types of ozone emitters can be used with advantage. Accordingly, you can produced and operated different ozone emission devices become. The areas of application of these facilities are arbitrary. Benefits arise z. B. in connection with air conditioning in which a cooling element or an evaporator with the emitted Ozone can be decontaminated or cleaned. Such air conditioners with ozone cleaning can be used with advantage in motor vehicles.

In The dependent claims are further advantageous embodiments of the invention.

The invention relates to a control and regulating device ( 9 ) for an ozone emitter ( 5 ). The invention further relates to an ozone emission device equipped therewith ( 4 ) and their use in an air conditioning system ( 2 ). The invention also relates to an operating method, in particular for controlling and optionally controlling an ozone emitter (US Pat. 5 ).

1 schematically shows a vehicle ( 1 ), in particular a motor vehicle, which is provided with an air conditioning 2 ) equipped with an ozone emission device ( 4 ) having. The ozone emission device ( 4 ) has at least one ozone emitter ( 5 ), which may be of any type and that is controlled by a control device ( 9 ) is applied. The ozone emitter ( 5 ) is z. B. in the vicinity of a cooling element ( 3 ), z. B. an evaporator, the air conditioning ( 2 ) arranged. The emitted ozone serves to decontaminate the cooling element ( 3 ) and possibly deposits there, especially bacteria or other pathogens.

2 illustrates in a block diagram the structure of the ozone emission device ( 4 ). The ozone emitter ( 5 ) works preferably according to the principle of dielectrically impeded discharge and z. B. formed as a planar module or in another suitable manner. The planar module ( 5 ) has z. B. two parallel electrically rechargeable electrode plates having a different size and between which a dielectric, z. As glass or the like. Is arranged. The electrode plates are surrounded by a gas, in particular air, with the field lines and the discharges passing through the gas. Here, plasma needles or so-called filaments form temporarily, through which a charge shift takes place and thus a current pulse flows. The discharges generate and emit oxygen ions or ozone.

The ozone emitter ( 5 ) is supplied by a high voltage generator ( 6 ) is applied with a high voltage in the form of an AC voltage or a pulsed DC voltage. From a certain voltage level, the ignition (Z) in the diagram of 4 marked, discharges start in significant numbers.

The ozone emitter ( 5 ), here z. B. the planar module, z. For example, if a basic capacity of about 16 to 22 pF is formed. During normal operation, plasma needles or so-called filaments form, their electrical effect appears as a parallel connection of a number 1 to N small capacities. With increasing ignition of the filaments, the ozone emitter behaves like a bipolar zener diode. From the exceeding of the ignition voltage, an additional charge transport through the filaments takes place, whereby the current at the planar element and thus also the recorded operating current of the high voltage generator ( 6 ) is strengthened and u. U. does not increase linearly. This behavior is exploited by the operating current and power control explained below.

The ozone emission device ( 4 ) further includes said high voltage generator ( 6 ), the z. B. a high voltage of about 4 to 6 kV generated, wherein z. B. the ignition voltage (Z) is about 4.5 kV. The fundamental frequency of the applied high voltage is for example at 60 kHz. The ignition of the filaments generates high-frequency voltage pulses which overlap the fundamental frequency as short-term drops in the voltage amplitude by, for example, 40 V to 100 V. The frequency of the filament currents is for example 5 MHz.

The high voltage generator ( 6 ) is connected to a voltage source or a power supply and has a transformer ( 7 ) on. The voltage source z. As the public network, a power storage, a generator, a power supply, or the like. Be. It can be stationary or unsteady and can z. In a vehicle ( 1 ), z. B. a motor vehicle or a trailer, in particular a caravan or the like .. are.

The Operating frequency can be compared to the grid frequency means an oscillator and / or converter in any suitable manner, z. B. with pulse width modulation, and changed to the aforementioned Base or excitation frequency can be increased.

Furthermore, a switchable and possibly controllable current-limiting device ( 8th ) is provided for the operating current in the operating circuit. It can be used in the high-voltage generator ( 6 ) be integrated. By limiting the operating current is also a limitation of the current flow at the ozone generator, which also can be protected from destruction.

The high voltage generator ( 6 ) is connected to the control device ( 9 ) connected in 3 is shown in more detail. Furthermore, the ozone emission device ( 4 ) or the control device ( 9 ) detecting means for the recorded operating current and / or the electric power. The detection device can, for. B. a measuring device ( 10 ) for the operating current of the high voltage generator ( 6 ) be. As a result, the current level and, if appropriate, the temporal current profile and its gradient can be detected. The measuring device ( 10 ) can transform the transformer ( 7 ) and measure the operating current on the primary side.

Furthermore, a detection device, in particular a measuring device ( 11 ) for the high voltage of the high voltage generator ( 6 ) to be available. Here too, in addition to the voltage level, its time course and the gradient can be recorded. The measuring device ( 11 ) can also be arranged on the primary side.

The Detection device for the recorded electrical Power can be designed in any suitable manner. she can z. B. have an evaluation, with the performance based on measured parameters, in particular the operating current and if necessary, the voltage is determined, in particular calculated. A Service entry can also be done in other ways.

In addition, another detection device ( 12 ) in the circuit of the ozone emitter ( 5 ) can be arranged. It detects the filament signals generated during operation. The detection device, not shown ( 12 ) can z. B. have a decoupling element, which consists for example of a parallel connection of a capacitor and an inductance and decouples the higher-frequency filament pulses.

While a positive and / or a negative half-wave of the acted upon High voltage can be the charge shifts generated by the filaments be disconnected and charge another capacitor. It is advantageous here, the charge shifts of positive and negative half-wave of the applied high voltage over rectify a diode bridge and charge the To add capacitor. The more filament formations per unit time take place, the faster the capacitor is charged. By Measurement of the potential applied to the capacitor or in it stored charge at predetermined time intervals, for example every 5 ms to 10 ms, thus can reduce the number of filament firings be approximated. It is also possible, the time to reach a certain state of charge of the capacity capture.

The object of the evaluation is no longer the number of filament pulses as in the prior art, but the electrical charge shifts contained therein and in particular the sum of the charge shifts from a plurality of filament pulses. From the charge behavior of the capacitor over time can be on the function of the ozone emitter ( 5 ) and the occurrence of discharges. In addition, the performance of the ozone emitter and the filament impulses can be recorded via the time-dependent recording of the charge behavior and used as an equivalent for the ozone production and stored in the control device ( 9 ) be evaluated.

The above-described detection and evaluation of the filament signals has independent inventive significance. The detection device ( 12 ) may alternatively or in addition to the operating current detection for the control and / or regulation of the high voltage generator ( 6 ) are used. The detection device ( 12 ) can thus alternatively or additionally to the detection or Measuring device ( 10 ) for the operating current and / or power. In the variant of an arrangement of the detection device ( 12 ) for the filament signals instead of the measuring device ( 10 ) for the operating current, the measuring device ( 11 ) maintained for the high voltage or alternatively omitted.

In a further variant, it is possible for the detection device ( 12 ) of the filament signals to use a different construction, for. B. from the WO 03/080507 A1 known detection and measuring device. Their arrangement is in addition to the operating current detection and to the measuring device ( 10 ) and possibly the measuring device ( 11 ) intended.

As 2 clarified in the overview, the measuring and / or recording devices ( 10 . 11 . 12 ) with the control device ( 9 ) connected. This in turn is connected to the high voltage generator ( 6 ) and emits an actuator signal ( 19 ) for the high voltage. It can also provide an actuator signal ( 20 ) for a current limit of the operating current and is for this purpose with the current-limiting device ( 8th ) connected.

In 3 is a particular and preferred embodiment of the control and regulating device ( 9 ). It has at least one controller ( 13 ), z. B. a micro-controller, which directly or indirectly with one or more of the measuring and detection devices ( 10 . 11 . 12 ) and the at least one functional module ( 14 ) for the control of the high voltage generator ( 6 ) and the regulation of the operating current for which the functional module ( 14 ) an actuator signal ( 19 ) emits to adjust the high voltage. The high voltage can u. U. also be regulated.

In one embodiment, a power control of the high voltage generator ( 6 ) and the ozone emitter ( 5 ) over the detected operating current and / or via a detection of the filament currents or filament signals instead. The operating current is regulated at a predetermined voltage range.

In a further variant, in addition a detection of special operating conditions of the ozone emitter ( 5 ), for which a detection module ( 16 ), which is in the controller ( 13 ) can be integrated or connected to this. With the acquisition module ( 16 ) may cause operational damage to the ozone emitter ( 5 ) are detected. These are z. B. deposits on the ozone emitter ( 5 ). These may be electrically non-conductive deposits in the form of dust or condensation. The deposits may also be electrically conductive and z. B. salt water, which in the ozone emitter ( 5 ) has penetrated what z. B. in air conditioning systems ( 2 ) in vehicles ( 1 ) can happen. For the detection of these deposits or other abnormal environmental or operating conditions of the ozone emitter ( 5 ) Any suitable signals can be generated and evaluated.

In the shown and preferred embodiment, those of one or more of the measuring and detecting devices ( 10 . 11 . 12 ) emitted signals for the operating current and / or the high voltage and / or the filament signals are detected and evaluated. There may also be a gradient evaluation. For this purpose, for. B. evaluated the operating current and / or the filament signals taking into account the current high voltage. The acquisition module ( 16 ) can with a memory element ( 17 ) for current and voltage characteristics and use the comparison values stored here for the evaluation of the signals obtained.

4 shows a current and voltage diagram for the course of the operating current (I) over the applied high voltage (V). The current increase after the start of ignition allows the operating current to be regulated to an operating point (A) via the high voltage. The current consumption increases before reaching the ignition voltage (Z) of the ozone emitter ( 5 ) linear with the applied high voltage. After the start of ignition (Z), the operating current increases disproportionately, with the line drawn with a solid line ( 21 ) reflects the normal current flow.

Through the controller ( 13 ) and the function module control ( 14 ), the ozone emitter ( 5 ) in normal operation to a stable operating point (A) are regulated. The resulting current and voltage values (I, A and V, A) are below the maximum values. There is a working area (T) for the high voltage, in which the z. B. specified for the operating point setpoint of the operating current to be achieved. Within this work area (T), via the function module control ( 14 ) a regulation of the recorded operating current or the electric power instead.

It There may be an automatic operating point determination. These can be z. B. realized by no Absoultwert for the setpoint current is specified, but only an offset to the measured Electricity is provided at the ignition point.

The other current courses ( 22 . 23 . 24 ) give the behavior in the existence of special operating conditions, eg. As the aforementioned deposits, by way of example. These current profiles are processed by the acquisition module ( 16 ) detected and out evaluates. In 5 is a flowchart for an operating current control in the start-up or start-up phase with the detection of the special operation cases salt water and condensate and shown with branches in subroutines. 8th shows a flowchart for the regular operation.

If z. B. electrically conductive deposits, the operating current increases disproportionately before reaching or at the latest in the range of the ignition point (Z), which in the diagram by the short-dashed line ( 24 ) is clarified. At the same time, the high voltage is below the working range (T). The acquisition module ( 16 ), this can be done, for example, at the gradient of the current ( 24 ) and the ratio of the disproportionately high current in the range of the ignition voltage or an evaluation of the absolute values. This is the trigger for a branch in the subroutine operating case saltwater.

Is there an electrically or poorly conductive deposit before, z. As condensation, this hinders the ignition and filament formation. The actual value of the operating current is below the setpoint. Despite the increase in voltage, the current increases only slowly and remains below the setpoint, with the high voltage exceeding the working range (T). This is indicated in the diagram by the line marked with longer dashes ( 22 ). Again, this can be the acquisition module ( 16 ) from the gradient of the current profile and the assignment to the voltage value on the basis of the predetermined characteristics and branch off into the sub-program operating case condensed water.

The third illustrated special case of the current profile ( 23 ) with the dotted line indicates the behavior with increasing humidity, dust-like deposition, aging of the ozone emitter ( 5 ) or other tolerance or signs of wear again. The operating current increases after the ignition (Z), although slower than the normal line ( 21 ), but the high voltage remains in the working range (T). Deviations of the operating current from the setpoint are achieved by adjusting the voltage via the control function module ( 14 ) adjusted. This shows 8th the sequence of the subprogram control operating current.

The other special states with the current curves ( 21 . 22 ) can in the simplest case also by the function module control ( 14 ) are readjusted.

For this purpose, the invention additionally provides for a special measure in the shown embodiment, which accelerates removal of such z. B. allows liquid deposits what z. B. can be done by evaporation. For this purpose, the abovementioned basic equipment of the control and regulation equipment ( 9 ) in addition to the control function module ( 14 ) a functional module control ( 15 ) for executing the mentioned subroutines operating case salt water or customer water in the controller ( 13 ) exhibit. The said functional modules ( 14 . 15 ) may be electrical circuits or software modules. The controller ( 13 ) can in principle be designed in any way, for. As a hard-wired circuit, as a logic device, as a microprocessor control or the like. Accordingly, the function modules ( 14 . 15 ) designed.

The function module control ( 15 ) and the control function can temporarily replace the normal control function and replace or overlay it. The function module control ( 15 ) can be actuator signals for the high voltage to the high voltage generator ( 6 ) and in addition an actuator signal current limit ( 20 ) to the current limiting device ( 8th ). As a result, the operating current is limited to a maximum value (Imax). The high voltage can also be limited to a maximum value (Vmax).

In the case of an electrically conductive liquid and a detected current profile ( 24 ) is in accordance with the flowchart of 6 the voltage is increased, the operating current being limited or controlled to the limit value (Imax). This has heating of the charged surface (s) of the ozone emitter ( 5 ) and evaporation of the electrically conductive liquid result. After the electrode surface has burned out, the high voltage returns to the normal value or working range (T) and, in the manner described above, it is returned to normal via the functional module control (FIG. 14 ). The time is set via a timer in the controller ( 13 ). If the high voltage does not return to the tolerance field (T) after the set time has elapsed, the above-described free-burn process can be restarted. If this does not result in a return of the high voltage to the working area (T), the high voltage generator ( 6 ) and a warning signal from the control and regulation device ( 9 ). The number of attempts to alarm can be changed.

In the case of a non-conductive liquid of the current profile ( 22 ) is in accordance with the flowchart of 7 also increased the high voltage. This can be done over a predetermined period of time until reaching the maximum voltage (Vmax), to enable ignition even under the liquid deposition and the ver ver steaming. This checks whether the operating current is still below the setpoint or an assumed tolerance range. After burning the electrode surface, the operating current again reaches the setpoint and it can be regulated normally.

In both cases with electrically conductive or non-conductive Liquid or other deposit form may be due to the Voltage increase and, if necessary, current or voltage limitation a very fast removal of the deposit can be achieved.

8th illustrates the operational case after switching on and starting the ozone emission device ( 4 ) and clarifies the control behavior when faults occur during operation due to condensation or salt water. As long as no malfunction of the acquisition module ( 16 ) is detected, a normal control behavior takes place, with any violations of the current setpoint with simultaneous location of the high voltage in the working range (T) or more lead to a reduction of the high voltage and a return of the operating current to the setpoint. On the other hand, if the setpoint is undershot and the high voltage is in or below the working range (T), the high voltage is increased and thereby also the operating current is returned to the setpoint.

If the operating current is above the setpoint value and at the same time the high voltage is below the working range (T), then there is the operating case of salt water, which at the beginning in connection with 6 described subroutine and the control and regulating function shown leads.

If the operating current is below the setpoint and at the same time the high voltage is above the working range (T), the operating situation condensed water is detected and entered into the 7 branches described subroutine.

Variations of the embodiments shown and described are possible in various ways. The ozone emitter ( 5 ) may have a cylinder or tube module or another embodiment instead of a planar module. In a simple embodiment, the acquisition module ( 16 ) and possibly also on the function module control ( 15 ) as well as the associated tax procedures are dispensed with. The controller ( 13 ) then causes a control according to the operating current and / or the filament or the filament signals. Furthermore, structural modifications of the components shown and described are possible.
