Definitions

  • This object is achieved according to the invention in that on the evaporator for generation the lower temperature at least two injection points are provided, of which each upstream of a throttle device with a different flow resistance and each of which can be controlled by a deflecting member.
  • control range of the in the series circuit of the Increase the size of the evaporator at the end of the evaporator if there is an alternative Embodiment of the subject of the invention is provided that the injection points are spaced apart on the evaporator to generate the lower temperature and a portion of the refrigerant channel arrangement of this evaporator between them take up.
  • the normal refrigerator compartment 15 Above the normal refrigerator compartment 15 is one Temperature of -18 ° C lying freezer 17 provided for cooling it in cross section essentially ⁇ -shaped (in the form of a lying U) evaporator 18 provided with a ceiling section, a rear wall and a floor section is.
  • the evaporator 18 is provided with a continuous over its ceiling section, its rear wall and its bottom portion extending refrigerant channel arrangement 19 equipped, which on their inflow side lying in the ceiling section Provide the end with two immediately adjacent refrigerant injection points 20 and 21 is, the refrigerant injection point 21 is followed by a channel section 21.1, which in an opening 21.2 lying after the injection point 20 in the Refrigerant arrangement 19 opens.
  • the refrigerant After flowing through the evaporator 14, the refrigerant is in the series circuit the evaporator is in the last position for cooling the normal cooling compartment serving evaporator 16, from where it is then in the gaseous state is sucked in on the refrigerant compressor 26 via the refrigerant line 27. Because of the low Spacing of the two injection points 20 and 21 in the ceiling section of the Evaporator 18 is an optimal degree of filling of the series connected in series Evaporator 14, 16 and 17 reached because of the in both modes of liquid refrigerant flow channel length is at least largely the same length.
