Definitions

  • the invention relates to a method for controlling a compressor set or a fan set, comprising one or more compressors or one or more fans.
  • the regulation of the suction pressure is done by switching on or off one or more compressors.
  • the regulation of the high pressure is done by switching on or off one or more fan levels.
  • the time delay t g is composed of a base switch-on time t b - which is assumed to be constant - and a variable switching time t v dependent on the control deviation.
  • switching times that are too long cause the permissible switching frequency of the compressor or fan to be exceeded.
  • the switching times are set at the time of commissioning of a refrigeration system or machine, but these are to be regarded as optimal only for the system state prevailing at startup.
  • DE 35 00 636 A1 describes a method for controlling the operation of a number of compressors, each of which is equipped with a capacity regulator which can gradually change the output of the compressor to provide a total output which meets the power requirements which is currently changing.
  • the control system is divided into a power control loop for responding to a relatively small load change and a compressor control loop for responding to a relatively large load change.
  • the compressors and the power regulators are started sequentially, measuring the periods of operation of the compressors and the power regulators.
  • the power control loop is further divided into a sub-loop for power controllers of a compressor that has worked the longest and is to be stopped first, and a sub-loop for the power controllers of the other compressors.
  • the no-load operation preferably starts at the lower loop for the power controllers of the first-to-stop compressor, while the load operation is first performed at the lower loop for the power controllers of the other compressors.
  • No. 5,231,846 A describes a method for the stepwise operation of compressors for a refrigeration system with a plurality of compressors, wherein the method comprises the following stages: a first operating state is calculated for each compressor, and a second operating state for each compressor. Furthermore, the status of each compressor is determined, thereby creating a first list of circuits with compressors that are available to be turned on and creating a second list of circuits with compressors that are available to be turned off. For the control of the compressors with the aid of the created lists, a distinction is made according to whether the cooling capacity is to be increased or reduced on the other hand.
  • Object of the present invention is to provide a generic method, which makes it possible to adjust the switching times of the compressor or fan to the respective current environmental conditions and / or to the respective required power requirements.
  • the maximum number of switching operations per hour per compressor or per fan is initially set to limit the switching frequency of the compressor or fan.
  • this parameter it is determined in which minimum intervals a compressor or fan can or may be switched on.
  • the maximum switching frequency is 10 switching operations per hour
  • a compressor or fan can therefore be switched on again every 6 minutes at the earliest; The prerequisite for this is, of course, that the compressor or fan was previously switched off.
  • a demand cycle time t az this is defined as a time interval between the switching on of a compressor or fan and the next time, to which there is again a cold or heat demand and delayed a compressor or fan is switched on.
  • connection of one or more compressors or fans takes place after a delay time t V_IN , the switching off of one or more compressors or fans after a delay time t V_AUS .
  • the on and off delay times t V_IN and t V_AUS are recalculated per compressor or fan respectively for the next demand cycle .
  • the on and off delay times are composed of a basic on-time t b and a variable switching delay or switching time t v .
  • the (shortest) switch-on blocking time t S_ON is distributed as a percentage to both delay times .
  • t V_AUS_B t V_AUS_B + ( t BE * ( 1 - P V_EIN ) * P LEG ) * P
  • t V_AUS_V t V_AUS_V + ( t BE * ( 1 - P V_EIN ) * ( 1 - P LEG ) ) * P
  • N stands for the number of compressors or fans that are switched on during a demand cycle time.
  • t g_EIN t V_EIN_B + t V_EIN_V .
  • t g_AUS t V_AUS_B + t V_AUS_V
  • the inventive method for controlling a compressor set or a fan set allows optimization of the switching times of the compressor and fan of a compressor or fan set. A manual optimization of the switching times - as is done so far - is unnecessary thanks to the method according to the invention.

    b) on détermine le temps de cycle des besoins tBZ qui est défini comme l'intervalle de temps entre la mise en marche d'un compresseur ou ventilateur et l'instant suivant auquel on a à nouveau besoin de froid ou de chaleur, et auquel un compresseur ou ventilateur est mis en circuit de manière temporisée,
    c) on détermine un temps de blocage de mise en marche tS_EIN par compresseur ou ventilateur, tS_EIN = tE - tBZ - tV_EIN et la temporisation tV_EIN avec laquelle un compresseur ou ventilateur est mis en service, étant prédéfinie,
