Definitions

  • the invention relates to a refrigeration device with a heat-insulating housing, within which at least two heat-insulating separated, a different Freezer compartment temperature having refrigerating compartments are provided, each of which Evaporator corresponding cooling capacity are cooled, which inflow side respectively have an upstream throttle device and which by at least one drive means each separately with a suction side upstream of a refrigerant collector Forced refrigerant compressor forcibly z ⁇ lztem refrigerant are acted upon, which in the standstill phase of the refrigerant compressor, at least to a certain extent in a refrigerant guide section of the evaporator higher Cooling capacity collects.
  • a freezer with at least two within its heat-insulating Housing arranged, thermally separated freezers, each of which is cooled by an evaporator known.
  • the freezers are fluidly connected to each other via a connecting line and over a control means acted upon by refrigerant.
  • the freezers are different Useful content.
  • the for cooling the freezer compartment with the larger net capacity serving evaporator is through a arranged in the connecting line shut-off device decoupled from the refrigerant flow and serves as a reservoir for liquid Refrigerant.
  • the invention is based on the object, in a refrigerator according to the preamble of Claim 1 with simple constructive measures to make such a way that on the one hand the disadvantages of the prior art are avoided and on the other hand a separate Temperature control of the cold storage is possible.
  • the refrigerant guide section in terms of its refrigerant receiving volume to at least approximately complete filling with liquid refrigerant in the standing time of the compressor designed is.
  • freezer compartment evaporator Due to the inventive design of the freezer compartment evaporator is at a Cooling requirement of the refrigerating compartment during start-up of the refrigerant compressor Pressure on the during the downtime of the refrigerant compressor in this refrigerant guide section accumulated liquid refrigerant exerted, causing this directly After starting the compressor from the freezer compartment evaporator in a refrigerant collector is transported and from this for cooling the refrigerator compartment evaporator for Available.
  • Verdamferabitess serving of the freezer evaporator acts on the accumulated liquid refrigerant at start-up of the compressor, a pressure difference, whereby the liquid then from the freezer compartment evaporator "entrained” and thus very quickly to the cooling of the Refrigeration compartment evaporator serving refrigerant circuit is supplied.
  • the refrigerant receiving volume of the refrigerant guide portion is smaller is greater than that during the uptime of the refrigerant compressor in the evaporator higher Cooling capacity accumulating amount of liquid refrigerant.
  • the evaporator higher cooling capacity formed when after a next preferred embodiment of the subject invention is that the evaporator higher cooling capacity designed as a freezer compartment evaporator is, in the functional position of the refrigerator at the lowest lying refrigerant guide section is smaller in terms of its refrigerant uptake volume, as the accumulating during the lifetime of the refrigerant compressor refrigerant there.
  • a complete filling of the refrigerant guide section can be in the case of made of a plate composite evaporator, for example, by a corresponding Reduce the channel cross section.
  • the evaporator higher cooling capacity than evaporator system is formed with a plurality of spaced-apart evaporator planes.
  • evaporators have both plate-like evaporator levels as well so-called wire tube evaporator proven, with the last type of evaporators of in the standing time of the compressor at least completely filled with liquid refrigerant Refrigerant leading section executed by a meandering pipe section is.
  • the refrigerant collector in the heat insulating material of the heat-insulating Housing is embedded.
  • the refrigerant collector in the catchment area one for the collection of the evaporator Tauauffangrinne provided for lower melt flow of melt water is arranged.
  • Such an arrangement of the refrigerant collector eliminates the need for heat insulation to prevent condensation for this, as in the case of condensation of the refrigerant collector accumulating condensation water directly into the already existing condensation water gutter is initiated.
  • Fig. 1 shows a simplified schematic representation of a fridge-freezer 10 with a heat-insulating housing 11, whose interior by a thermally insulating formed horizontally disposed partition wall 12 in two sections is divided, of which the higher-lying portion formed as a cooling compartment 13 is.
  • a platinum-type executed evaporator with a Refrigerant channel 15 is provided, which at its inflow end a refrigerant injection point 16 has.
  • a freezer compartment 17 provided, which of a example, as a wire tube evaporator trained evaporator 18 with in the present case three vertically spaced one above the other arranged by appropriate shaping of a single pipe produced evaporator planes 19, 20 and 21 is cooled.
  • the ground-level evaporator level 21 as the other two evaporator levels 19 and 20 one from a continuous meandering shaped Pipeline formed refrigerant guide section 22, which by its dimensions, namely its inner diameter and its length, a cold receiving volume which has at least one complete filling of the refrigerant guide section 22 with liquid refrigerant 23 (see Fig.
  • the refrigerant collector 27 is connected via a suction line 28 with a refrigerant compressor 29, which is connected on the pressure side to a condenser 30, its output side, for example, with an electrically controllable 3/2 way solenoid valve 31 is connected.
  • the 3/2 way solenoid valve 31 is used to control the from Refrigerant compressor 29 forced ungeälzten refrigerant 23 to the evaporators 14 and 18, wherein the solenoid valve 31 in a control position I, the liquid refrigerant 24 via a throttle 32 to the freezer compartment evaporator 18 deflects out where it over the Layers 19 to 21 is led to the cooling.
  • the refrigerant 23 flows when the refrigerant compressor is in operation 29 via the connecting line 24 to the branching point 25 and from there to Refrigerant collector 27 in the suction side to the refrigerant compressor 29 connected Suction line 28.
  • the solenoid valve 31 has a control position II, in which the forcibly circulated liquid refrigerant 23 via a the Evaporator 14 upstream throttle 33 is supplied to the evaporator 14, of which it at the outflow end via the branching point 25 and the refrigerant collector 27 is again supplied to the refrigerant compressor 29 via the suction line 28.
