Definitions

  • the period following one after the end of the period the application of liquid refrigerant to the evaporator Delay time is provided.
  • the delay time is particularly easy to implement if after a next advantageous one Embodiment of the subject of the invention is provided that the delay time is determined by a predetermined period of time.
  • the delay time is provided in a particularly interference-free manner if, after a further advantageous one Embodiment of the subject of the invention is provided that the predetermined Period of time for the delay time by an electronic evaluation circuit is specified.
  • the fan is particularly effective and has a long service life when it is operated a further preferred embodiment of the subject matter of the invention is provided, that the time spans are at least approximately of the same length and from each other are spaced apart by the delay time.
  • the fan by exceeding a predetermined temperature difference is put into operation, which by at least two the room temperature in Cold room temperature sensor is determined, one of which is in the lower region of the Cold room and the other is arranged in the upper area.
  • a fan 15 which, like the evaporator 14 is covered by an intermediate wall 16. This is on the cooling surface of the Evaporator 14 facing side with air guide channels 17, which in outlet openings 18 emerge in the area of the cold room ceiling and which both through deflections a different heat exchange due to changes in cross-section between the air flow guided therein, which is based on the fan 15 is forcibly conveyed over the evaporator 14 and the cooling surface of the evaporator 14 allow.
  • a closed-walled container 19 formed as a vegetable dish provided, by its arrangement not only towards the rear wall of the cooling space 13, but also an air duct 20 is also formed towards the bottom thereof and towards the door 12, by means of which the cooling air forcibly circulated by the fan 15 after it is extinguished Air outlet openings 18 to achieve a uniform temperature level within of the cooling space 13 to the door 12 and directed along and ultimately from the suction side the fan 15 is detected.
  • the fan 15 is operated to generate the uniform temperature level within the cooling space 13 during the entire period t k provided for the application of liquid refrigerant to the evaporator 14. After reaching the intended cold room temperature, the fan 15 is put out of operation simultaneously with the interruption of the refrigerant flow to the evaporator 14. Following this, during the time in which the refrigerant flow to the evaporator 14 is interrupted, the fan 15 is started up again after a delay time t v for a period of time t y , the period of time t y being significantly shorter than the period of time t k, which corresponds to the time for the application of the evaporator 14 with liquid refrigerant.
  • the number of time periods t y provided for short-term operation of the fan 15 is determined by the duration of the delay time t v and the duration of the rest period between two time periods t k , with tests for a cold room with a cold room volume of approximately 0 , 2 m 3 a delay time t v of 10 minutes and a time span t y of two minutes have already given good results with regard to a significant reduction in the temperature stratification within the cooling space 13.
  • the control of the fan according to the invention results 15 between the measuring points I to III clearly compared to the prior art reduced temperature stratification and at the same time a temperature inside the vegetable skin 19, which is clearly above the freezing point, so that stored goods are stored therein such as cucumber or salads or the like cannot freeze.
