Definitions

  • the defrost heater is not touched regardless of the mains voltage, i.e. switched on with a duty cycle of 100%. As already mentioned above, this can lead to the fact that heating occurs either too much or too little when voltage fluctuations occur, since the heating power varies in proportion to the square of the supply voltage of the defrost heater. If there is too little heating, the defrosting process is often incomplete; if there is too much heating, there is an unnecessary waste of energy.
  • the defrost heater including, if applicable, a channel heater
  • the supply voltage generally the mains voltage
  • a step function corresponds to a subdivision of the value range of the supply voltage into several intervals, each interval being assigned one of the discrete values of the step function.
  • the interval limits are preferably set such that the upper and lower limits are in a ratio which is essentially the same for all intervals, preferably with a value between 1.1 and 1.2 ,
  • the heating power increases proportionally with the square of the voltage, as shown by the dashed curve in FIG. 3.
  • the heating power at the nominal voltage of 230 VAC is set to 100% here. If the actual supply voltage of the refrigeration device is not 230 V, but 160 VAC, for example, only a heating output of approx. 50% is achieved. If a fixed heating period is preset for a defrosting process, which is dimensioned so that the Nominal voltage completely defrosts an expected amount of ice on the evaporator 7, so only half of this amount defrosts at 160 VAC. If the actual supply voltage is above the nominal voltage, the defrost heater 8 emits more heat than required when defrosting. For example, a heating output of approx. 160% is already achieved at 290 VAC. This means that 60% of the heating energy is not required for defrosting and only affects the energy balance of the refrigerator.
  • the supply current for the defrost heater 8 is an alternating current
  • the period of the keying comprises a plurality of its periods, so that a linear relationship between the duty cycle and the heating power is guaranteed.
  • a usual frequency of the alternating current of 50 or 60 Hz, this requirement is fulfilled in any case if the test period is longer than 1 s.

Abstract

L'invention concerne un appareil frigorifique à résistance de dégivrage intégrée (8), lequel appareil comporte un circuit d'enregistrement (10, 12), conçu pour enregistrer une valeur de tension au niveau d'un raccord d'alimentation (11) de la résistance de dégivrage (8) et pour produire un signal de commande échantillonné dont le rapport cyclique dépend de la valeur de tension enregistrée, ainsi qu'un disjoncteur (9) actionné par ce signal de commande et destiné au courant d'alimentation acheminé à la résistance de dégivrage (8). Le rapport cyclique du courant d'alimentation est réglé par l'intermédiaire de ce disjoncteur en fonction de la valeur de tension enregistrée, ce qui permet de limiter des variations de puissance de la résistance de dégivrage engendrées par des variations de tension.
