  • a blocked valve This may in particular be a blocked suction or pressure valve.
  • a solenoid valve in the cooling circuit may be defective, which solenoid valve does not necessarily have to be part of the refrigerant compressor.
  • the blocked valve in any case has the consequence that refrigerant in the cooling circuit is no longer transported in the extent required for cooling or not at all and therefore cooling can no longer take place.
  • the application device driving the refrigerant compressor e.g. a refrigerator, determines that the temperature does not drop, and then usually regulates the refrigerant compressor to maximum cooling capacity, so that the electric motor runs at maximum speed - of course, without success, because the coolant in the cooling circuit can not be transported.
  • the increase in the temperature of the compressor for example, over a certain limit temperature to define as a termination condition. That is, the temperature is constantly monitored, and when the limit temperature is exceeded and the electric motor preferably runs at maximum speed, the electric motor is turned off.
  • a disadvantage of this known method is that it does not work for all refrigerant compressors.
  • the practice shows that depending on the design or type of refrigerant compressor, the temperature sometimes does not rise far enough to be able to determine a limit temperature meaningful.
  • maximum speed is always to be understood as the maximum speed that the refrigerant compressor or the electric motor actually achieves in the current cooling circuit. This maximum speed may differ for different reasons from a theoretically technically possible maximum speed of the electric motor, for example, because of noise reasons, the application device does not exploit or request the theoretically technically possible maximum speed of eg 4000 min -1 , but as a "target maximum speed” one lower speed of eg 3600 min -1 predetermines.
  • a typical monitoring parameter would be the current consumption of the electric motor, which after rising to a maximum, for example, 0.85 A, within a certain period of time to a certain value - for example, to 0.425 A - goes back, while the electric motor is constantly running at maximum speed.
  • the blocked valve may be a blocked suction or pressure valve.
  • the blockage condition can also be triggered by another defective element in the cooling circuit, such as a solenoid valve, which element does not necessarily have to be part of the refrigerant compressor.

  • the monitoring parameter is a current absorbed by the electric motor or a temperature of a control electronics of the refrigerant compressor, in particular of the electric motor, or of a motor winding of the electric motor.

  • Monitoring parameter can initially assume its maximum value X max . Otherwise, there is a risk that the value of the monitoring parameter will increase even further until the equilibrium of the pressure conditions is reached. Therefore, it is provided in a preferred embodiment of the method according to the invention that the determination of the maximum value X max occurs only after an initiation period after detection of the maximum speed of the electric motor. In other words, the detection of the maximum speed defines a start time or a start time for the method. In the mentioned preferred embodiment, immediately after the start time or after the start time, the initiation time interval is awaited before the determination of the maximum value X max of the monitoring parameter is performed.
  • the optimum initiation time span can be determined in the trial for different refrigerant compressor types and then set accordingly, with the initiation period typically being a few minutes. It is therefore provided in a preferred embodiment of the method according to the invention that the initiation period is at least 5 minutes, preferably at least 10 minutes, more preferably at least 15 minutes.
  • a verification can take place in that the monitoring parameter is again determined shortly after its last determination and compared with the maximum value X max . Even if this comparison indicates the blockage condition, it can be assumed with very high certainty that the blockage condition or a blocked valve is actually present. Therefore, it is provided in a preferred embodiment of the method according to the invention that after a verification period after the detection of the blocked valve, a value X t2 of the
  • Monitoring parameter is determined and the detection of the blocked valve is verified when X t2 is less than X max and (X max - X t2 ) / X max ⁇ ⁇ X applies. Waiting the verification period should thereby take into account any fluctuations in the monitoring parameter, ie if the value of the monitoring parameter is correspondingly low even after the verification period, it can be assumed with high probability that this reduction is not due to a random fluctuation.
  • the optimal verification period may be determined in trial for different types of refrigerant compressor and then set accordingly, with the verification period typically being no more than a few minutes.

  • the cause of the blockage situation sometimes no longer exists after a restart of the refrigerant compressor.
  • a solenoid valve had triggered the blocking situation because it had not opened and thus blocked the cooling circuit, and that this solenoid valve now opens as planned when it is restarted. Therefore, it is provided in a preferred embodiment of the operating method according to the invention that the electric motor is restarted after a second period of time.
