Definitions

  • the invention relates to a method for operating a refrigerator with one of one Evaporator cooled refrigeration compartment and a compressor, which the evaporator with Refrigerant and which when an upper temperature value is reached switched on and switched off when a lower temperature value is reached, the temperature values being recorded by a temperature sensor.
  • the compressor In order to maintain the intended after a longer standstill of the compressor Temperature in the refrigeration compartment necessary low evaporator temperatures To achieve this, the compressor must have relatively low evaporation pressures on its suction side to evaporate the refrigerant present in the liquid phase in the evaporator generate, whereby the efficiency of the refrigerant compressor, i.e. its power consumption in the form of electrical energy and its output in the form of suction power is significantly reduced.
  • the invention has for its object a method for operating a refrigerator to improve according to the preamble of claim 1 with simple measures such that the disadvantages of the prior art are avoided.
  • Cooling a refrigeration compartment serving runtime decreases the evaporation temperature of the Refrigerant in the evaporator does not drop to temperatures as they are in a conventional, continuous operation of the refrigerant compressor during its running time which results in a significantly higher compressor efficiency, i.e. the energy consumption of the compressor is evident from its intermittent operation lowered.
  • the regulation of the temperature in the refrigeration compartment can, for example, via the Standing time of the compressor or alternatively by an intermittent operation of the compressor which is appropriately adapted with regard to its active and passive phases.
  • the time values can be prepared in a particularly fail-safe manner if they are advantageous Embodiment of the object of the invention is provided that the time values for the intermittent operation of the compressor by means of discrete electronic components formed control logic are provided.
  • time values are particularly easy to adapt to different applications, if provided according to an alternative embodiment of the subject of the invention is that the time values for the intermittent operation of the compressor through in one Process computer stored data are provided.
  • the time values for the running times of the compressor in a range between 2.5 min and 10 minutes.
  • the compressor is switched off after reaching a predetermined duration and the evaporator is defrosted by the temperature sensor becomes.
  • the control for defrosting the evaporator is particularly easy to implement, if provided according to an alternative embodiment of the object of the invention is that the compressor is switched off after a predetermined period of time and the evaporator has been defrosted by a temperature sensor becomes.
  • a compressor of a refrigerator was operated with a first relative duty cycle (RED 1 ) of 11% and a second relative duty cycle (RED 2 ) of 20%, and the middle ones in the refrigerator compartment of the Refrigerator obtained air temperatures and their tolerance levels determined. From the determined, including their tolerance levels in curves and The mean air temperature for the refrigerator compartment was interpolated in accordance with the regulations to the mean air temperature of 5 ° C in the refrigerator compartment that is prescribed for the standard energy consumption. Above the curves and is the curve shown for the standard energy consumption shown, which is based on the interpolated average refrigerator compartment temperature of 5 ° C from RED 1 and RED 2 and which shows the effects of an increasing compressor runtime on the standard energy consumption.
  • RED 1 first relative duty cycle
  • RED 2 second relative duty cycle
