Definitions

  • the invention relates to a method for reducing noise on a Machine set comprising at least one frequency converter.
  • machine set below all known arrangements of compressors, pumps, fans and similar aggregates, which at least a frequency converter is assigned to understand. In particular, they are among them Variable speed compressor sets and variable speed condenser and Recooler, as used in refrigeration and air conditioning systems, to understand.
  • the clock frequency of To change or increase frequency for example, 2 or 4 kHz to 12 or 15 kHz. This causes a motor generated by a motor Noise level can be lowered.
  • the permissible current of the frequency inverter is limited or reduced. This happens to prevent excessive thermal load on the engine components.
  • Object of the present invention is to provide a generic method for Reduction of noise on a machine set to indicate the opposite has the known state of the art advantages.
  • the inventive method is first determined whether the by the machine set caused a pre-set or presettable noise level exceeds.
  • the presence of persons in the (immediate) Environment of the machine set selected As sensors come here For example, IR sensors, stepless proximity switches or conventional Motion detector used.
  • the clock frequency of or Frequency converter changed again, preferably the original again Clock frequency is set.
  • the clock frequency is not a preset and / or Preset value raised.
  • a minimum life which can not be exceeded may, be defined, with a summation of the already completed terms each reflects the current state of life.
  • Process is a continuous and / or discontinuous change of Clock frequency feasible.
  • the clock frequency is preferably flowing or in a demarcated Range - ie between a set or adjustable minimum and Maximum value - changed.
  • the inventive method allows disturbing noises at least always avoid if a preset or presettable Noise level is exceeded and / or at least one person is the Machine set approaching.
  • the parameter lifetime of the respective Machine set or its aggregates such as compressors, condensers, etc. considered.
  • the inventive method also allows the realization of Machine sets with conventional compressors, condensers or recoolers can work. So there are no, especially adapted to higher clock frequencies Aggregates, such as special motors, as known from the prior art are known required. Furthermore, it is now no longer necessary Components or units of a machine set on the actual required level to dimension out.
