  • variable amount of refrigerant energy-consuming storage means or inefficiently used condenser can be used.
  • the parallel arrangement of several evaporators due to the dual design of the injection system (valve, throttle capillary, injection point) leads to significant additional costs compared to single circuits.
  • the object of the invention is to find a cost-effective refrigerated cabinets with at least two thermally separated compartments and a suitable method for operating this cabinet in which a subject specific temperature control using only a single common refrigeration cycle and given a uniform, modular production of evaporator components is possible ,
  • each of these compartments is associated with an evaporator.
  • an expansion valve and these evaporators are connected in series in a refrigerant circuit.
  • at least two states with different non-vanishing flow coefficients can be set on the expansion valve.
  • the invention is thus based on a targeted change in the flow coefficient of an expansion valve in the refrigerant circuit of a refrigerated cabinet.
  • the refrigerant flow through the evaporator of the refrigerator can be changed specifically.
  • this causes a change in the ratio of liquid to gaseous refrigerant in the individual evaporators, and thus a change in the cooling capacity available in the evaporators.
  • the advantages of the invention are particularly useful in multi-zone refrigeration appliances, in which individual subjects such as freezer compartment, normal refrigeration compartment, basement compartment and / or 0 ° compartment to be individually supplied and actively controlled.
  • the expansion valve In order to enable a targeted control or regulation of the refrigerant flow through the evaporator, it is conceivable on the one hand to design the expansion valve such that its flow coefficient is infinitely adjustable. On the other hand, it is also very possible to carry out the expansion valve with switchable discrete flow coefficients. Such a discrete switchability is particularly useful in embodiments of refrigerated furniture, which have a few thermally separated compartments.
  • thermoly separated compartments of the refrigerator temperature sensor are connected to an evaluation circuit for signaling a refrigeration demand in the individual compartments, this evaluation circuit forming part of a temperature control. If this temperature control is signaled via one of the temperature sensor in at least one of the compartments of the refrigerator furniture cooling demand, through which the flow coefficient of the expansion valve is adjusted so that the refrigerant flowing through it is preferably evaporated in the compartment in which the refrigeration demand was detected.
  • a refrigerator with at least two thermally separated compartments can be provided, each of the compartments is associated with an evaporator, in which an expansion valve and these evaporators are connected in series in a flow of refrigerant through the refrigerant circuit.
  • At the expansion valve at least two states with different non-vanishing flow coefficients are adjustable.
  • a refrigeration unit comprises at least two compartments that are thermally separated from each other, wherein each of the compartments is associated with an evaporator in which an expansion valve and these evaporators are connected in series in a refrigerant circuit through which refrigerant flows, wherein at least two states with different non-vanishing flow coefficients are connected to the expansion valve are adjustable.
  • the flow coefficient of the expansion valve is infinitely adjustable.
  • the expansion valve is switchable between discrete values of the flow coefficient.
  • the expansion valve comprises two parallel line sections and a blocking member for shutting off one of the two line sections in one of the two states.
  • a third state is further adjustable on the expansion valve, in which it is impermeable to the refrigerant.
  • the evaporators are formed on a common carrier.
  • a reservoir located downstream of the condenser, which serves to receive or temporarily store liquid refrigerant, is located in the refrigeration circuit.
  • the thermally separated compartments each have a temperature sensor associated with them, these temperature sensors are connected to an evaluation circuit for signaling a refrigeration demand, which forms part of a temperature control.

  • a high flow coefficient of the expansion valve is set and a low flow coefficient of the expansion valve is set when refrigerant demand is detected in a compartment whose evaporator is close to the expansion valve.
  • the expansion valve when there is no refrigeration requirement in any of the compartments of the refrigerated cabinet, the expansion valve is kept closed.
  • a refrigeration unit was used with only two subjects to simplify the presentation.
  • the invention is not limited to such an embodiment, but can be transferred by expert action thereof on cooling furniture with any number of subjects.
  • the Fig. 1 shows a refrigerated cabinet 20, which has two compartments 21, 21 ', which are to be regulated to different temperatures. Each of the compartments 21, 21 'is associated with an evaporator 2, 2'. These evaporators 2, 2 'lie in a refrigerant circuit 1 through which refrigerant flows in series behind a compressor 3, a condenser 4 and an expansion valve 5.
  • Each of the compartments 21, 21 ' is associated with a temperature sensor 12, 12'.
  • These temperature sensors 12, 12 ' are connected to an evaluation circuit 11 for signaling a refrigeration demand, which forms part of a temperature control 10.
  • the temperature control 10 switches on the compressor 3 via a control line 14 when refrigeration demand is detected in one of the compartments, and off again when no more refrigeration demand is detected.
  • the temperature control controls 10 in the signaling of a refrigeration demand in at least one compartment 12, 12 'via a control line 13, the expansion valve 5 to adjust depending on the detected refrigeration demand whose flow coefficients.
  • the temperature control 10 at the expansion valve 5 will enter one of two discrete non-zero values of the flow coefficient, namely a low refrigeration requirement in the compartment 21' and a high value Refrigeration demand in compartment 21.
  • the passage coefficient of the expansion valve 5 is set small by the temperature control 10, more refrigerant is extracted by the compressor 3 from the evaporators 2, 2 ', as is introduced via the expansion valve 5 in the evaporator 2, 2'.
  • the pressure in the evaporators is low, the evaporation temperature accordingly low. In this way, the refrigerant evaporates only in the vicinity of its exit point from the expansion valve 5, in the evaporator 2 ', and essentially only the compartment 21' is cooled.
  • the passage coefficient of the expansion valve 5 is made large by the temperature control 10. Since less refrigerant is sucked through the compressor 3, as is introduced via the expansion valve 5 in the evaporator 2, 2 ', the pressure in the evaporator and, accordingly, the boiling point of the refrigerant increases. If it is higher than the temperature of the compartment 21 ', the refrigerant passes through the evaporator 2' without evaporating, and first evaporates in the evaporator 2 of the warmer compartment 21. In this way, substantially only the compartment 21 'is cooled.
  • a mean transmission coefficient can be selected if there is a simultaneous need for refrigeration in both compartments 21, 21 '. Then in each case a part of the refrigerant evaporates in the evaporator 21 'and the rest in the evaporator 21st
  • the same average transmission coefficient can be selected if the compartment 21 'has an unusually high refrigeration demand, for example during rapid freezing of newly stored refrigerated goods.
  • a refrigerator has three or more fans cooled by series-connected evaporators, and an expansion valve upstream of the evaporators in a refrigerant circuit is switchable between at least as many values of the transmission coefficient as there are compartments.
  • the values are each chosen such that, when one of these values is set, the evaporation of the refrigerant takes place predominantly in an evaporator assigned to this value.
  • the value of the passage coefficient assigned to an evaporator is the higher the further downstream the associated evaporator lies in the refrigerant circuit.
  • an expansion valve with continuously variable transmission coefficient can be used. Particularly simple and sufficient for most applications are expansion valves where only a small number of discrete values of the transmission coefficient are adjustable.
  • Fig. 2 Three possible embodiments of this suitable expansion valve 5 are shown. All embodiments are the same splitting (for example by means of T-piece) of the main line 31 of the refrigerant circuit at the entrance to the expansion valve 5 in two parallel conduit paths. After this splitting, these two conduction paths are fed to a blocking member 30.
  • This locking member 30, z. B. a directional control valve has a first switching stage, in which both conduction paths are shut off, a second switching stage, in which one of the two conduction paths open and the other is shut off, and a third switching stage, in which the other conduction path is open, wherein the a conduction path in this third switching stage may be open or disabled.
  • a capillary tube 34 At the exit of the locking member 30 is a capillary tube 34, which opens in a conventional manner directly into the evaporator 21 '.
  • expansion valve 5 When in the Fig. 2a ) outlined above exemplary embodiment of the expansion valve 5 include the above-mentioned parallel guided conduction paths upstream of the inputs of the locking member 30 capillary tubes 32, 33 of different length and the same cross-section. Depending on the switching stage of the blocking member 30, the refrigerant flows through the capillary tube 32, the capillary tube 33 or through both parallel, resulting in each case different flow coefficients of the expansion valve 5.
  • a multi-stage controllable expansion valve is not on in the Fig. 2 limited embodiments shown.
  • orifices can be used in an otherwise spacious refrigerant line.
  • More than two non-zero values of the flow coefficient can be realized by providing a four-position directional control valve corresponding to the four possible combinations of "open” and “locked” of the two branches, or by making the main line 31 in the expansion valve 5 more than two parallel, individually switchable line branches is split.
