Definitions

  • the invention relates to a method for operating at least one fan.
  • the invention relates to a system for carrying out such a method.
  • the present invention is therefore based on the object of designing and developing a method for operating a fan in such a way that noise-optimized operation is made possible with simple means. Furthermore, a system for carrying out such a method is to be specified.
  • the underlying object is achieved by the independent claim 12.
  • This specifies a system for carrying out the method according to one of Claims 1 to 11, with at least one fan, preferably having an electric motor, at least one sensor for recording a measured value, in particular a sound pressure and/or a structure-borne sound vibration, and a computing unit for the determination acoustic and/or psychoacoustic characteristic values for at least one defined time interval and/or for at least one defined operating point.
  • the underlying object can be achieved by determining acoustic and/or psychoacoustic parameters based on measured values and by operating the fan or fans taking these acoustic and/or psychoacoustic parameters into account.
  • the measured values are recorded by sensors, which are preferably a sound pressure, a structure-borne sound vibration or something else that can be measured environmental influence can act. These measured values are used as parameters by a computing unit in order to determine the actual acoustic and/or psychoacoustic characteristic values.
  • the method according to the invention and the system according to the invention make it possible for applicable immission control laws to be complied with in an ideal manner.
  • time-of-day-dependent immission limit values are also complied with, for example by using a night-time operation profile (operation as efficient as possible when people are absent) and a daytime operation profile (sounding as pleasant as possible acoustically when people are present) for the operation of the fan or fans.
  • a night-time operation profile operation as efficient as possible when people are absent
  • a daytime operation profile sounding as pleasant as possible acoustically when people are present
  • Fading out impermissible operating points can advantageously be compensated for by shorter and/or longer operation at permissible operating points. This achieves the advantage that operation in an acoustically and/or psychoacoustically desired range is made possible and, furthermore, the necessary power is provided by the fan or fans.
  • a loudness and/or a volume level and/or a sound pressure level and/or a sound power level and/or a specific frequency component for example a third-octave level, and/or a tonality and /or a roughness and/or a sharpness and/or a degree of fluctuation and/or a psychoacoustic annoyance and/or a tonality and/or an impulsiveness is/are determined.
  • These characteristic values have the advantage that they represent a determinable and comparable indication of the subjective, human perception.
  • An operating time and/or a speed and/or a torque and/or a power consumption and/or an angle of attack and/or a nozzle cross section and/or a flap position in a flow duct and/or /or external hardware and/or other fans are used for noise cancellation.
  • the above manipulated variables have an influence on at least one of the acoustic and/or psychoacoustic characteristic values in question, so that these characteristic values can be influenced in a targeted manner.
  • a regulation can be defined on the basis of the determined acoustic and/or psychoacoustic characteristic values, so that the fan is operated subject to this regulation.
  • the regulation can take place by comparing an actual value of an acoustic and/or psychoacoustic parameter with a target value of an acoustic and/or psychoacoustic parameter. It is thus possible to maintain a desired operating profile or a desired operating point which, for example, has the best possible acoustic euphony for people and the environment, for example through very quiet operation or operation with very few tonal components.
  • the acoustic and/or psychoacoustic characteristic values can be used to control the motor, for example by directly comparing the actual value with a setpoint value or by directly comparing the actual value with a limit value.
  • These can be stored in a database, for example after an initialization run-up.
  • An initialization run-up is generally understood to mean that during the first (re-)commissioning of one or more fans, the acoustic and/or psychoacoustic behavior is logged over the entirety of all or selected operating points. Individual applications of one or more fans can be taken into account.
  • the acoustic and/or psychoacoustic characteristic value could be adjusted according to the regulation.
  • central control can be implemented on an electric motor of a fan.
  • Such a configuration is particularly suitable if only a single fan is arranged. With a plurality of fans, this arrangement has the advantage that each fan can be controlled independently of the other fans in a simple manner.
  • a decentralized regulation preferably for electric motors of several fans, is implemented. This makes it possible to control the fans as a unit, so that combinatorial effects can be used.
  • fans can be arranged.
  • the load can be distributed so that the fans are operated at a permissible operating point overall. For example, instead of running two fans at full load, four fans can be run at half load. With such a load distribution, the fans as a whole can comply with immission limit values and immission guideline values.
  • another acoustic and/or psychoacoustic parameter is at least reduced by a targeted adjustment of an acoustic and/or psychoacoustic parameter.
  • the tonality can be reduced by raising a sound power level.
  • the sound of a further, louder fan can be covered by several quieter fans.
  • counter-noise can be applied in a targeted manner in order to reduce or eliminate disturbing noise. So-called active noise canceling is thus implemented.
  • the computing unit can take into account whether a person is present in the vicinity of the fan. If it is recognized that no person is present, the device can be operated at a louder operating point, for example.
  • the measured values can be used to detect anomalies in the operation of the fan. For example, bearing damage, contamination, an imbalance, material fatigue, a manufacturing defect, resonance, a stall and/or nozzle whistling can be detected.
  • This has the advantage that if there is a change in the acoustic behavior during operation (e.g. due to dirt, damage, material fatigue, etc.), the operating range of the fan can be restricted accordingly. This ensures regular operation until an acoustic anomaly is resolved.
  • An acceleration sensor and/or a sound pressure sensor and/or a soft sensor/virtual sensor and/or sensors for describing the operating state and/or the operating environment and/or the manipulated variables can be used in a particularly advantageous manner.
  • 1 shows a schematic representation of an exemplary embodiment of a system according to the invention, which is also used to explain the method according to the invention
  • 2 shows a schematic representation of an example of the permissible range of a manipulated variable
  • FIG. 3 shows a schematic representation of an example of an impermissible range of a manipulated variable
  • FIG. 1 shows a schematic representation of an exemplary embodiment of a system according to the invention. This has two fans 1, T, which are preferably driven by electric motors, not shown. Furthermore, two sensors 2, 2' and a computing unit 3 are provided. It is pointed out that the system can also only have a single fan and/or a single sensor.
  • Measured values such as a sound pressure and/or a structure-borne sound vibration, are recorded via the sensors 2, 2'. These measured values are transmitted to the processing unit 3, for example a computer.
  • the computing unit 3 uses the measured values as parameters in order to determine acoustic and/or psychoacoustic characteristic values for at least one defined time interval and/or for at least one operating point, for example a loudness, a sound pressure level, a specific frequency component, etc.
  • the fans 1, T are operated at permissible operating points in which the acoustic and/or psychoacoustic parameters are within a defined range, so that, for example, limit values are met and/or people do not hear the noise generated by the fans 1, T feel uncomfortable.
  • the system is designed so that a control based on the determined acoustic and / or psychoacoustic Characteristics can be defined.
  • the fans 1, 1' can thus be regulated by comparing an actual value of a psychoacoustic characteristic with a target value of an acoustic and/or psychoacoustic characteristic.
  • the regulation could also take place by comparing an actual value of an acoustic and/or psychoacoustic characteristic with a limit value of an acoustic and/or psychoacoustic characteristic. This makes it possible to maintain a desired operating profile by adapting one or more manipulated variables, for example the motor control, if necessary.
  • the sound pressure level L p is entered as an acoustic and/or psychoacoustic parameter. In this representation, an almost monotonously increasing course of the sound pressure level L p is assumed with a linear increase in the manipulated variable, for example the engine speed.
  • the permissible range of the manipulated variable is defined by a lower and an upper sound pressure level Lp .
  • FIG. 3 shows an impermissible range of a manipulated variable.
  • the sound pressure level L p is plotted as an acoustic and/or psychoacoustic parameter.
  • the permissible range of the manipulated variable is limited by a limit value.
  • the permissible operating range is limited by a limit value, which is constant for all speeds in the case shown.
