Definitions

  • the invention relates to a refrigerator with two thermally separated compartments, the evaporator are together with a compressor and a condenser in a refrigerant circuit and are acted upon by the compressor at a signaling of a refrigeration demand in the subjects with liquid refrigerant, wherein the amount of cold contributing cooling controlled is. Furthermore, the invention relates to a method suitable for operating this refrigerated appliance.
  • German Auslegeschrift DE 23 50 998 described a refrigeration cabinet with single circuit, which is designed inexpensively with only a single entry point for the refrigerant in the evaporator.
  • a freezer compartment and a normal refrigeration compartment each evaporator are assigned, which are connected in series in the refrigeration cycle.
  • this series connection of the evaporator has the disadvantage that the dimensioning of the individual evaporator must be made according to the refrigeration demand existing in the individual subjects, or the temperature requirements given there. Consequently, the design of the evaporators can not be optimized with regard to a desired energy efficiency, since for this purpose the evaporators would have to be designed as large as possible.
  • the temperature of the individual compartments can not be adjusted independently of each other, since in such refrigeration units with cooling required in a downstream in the refrigerant flow compartment also takes place in the upstream of this compartment subjects cooling.
  • cooling furniture in the refrigerant circuit in front of a branch leading to the evaporators, a reservoir for the intermediate storage of liquid refrigerant. From this it is possible to introduce additional refrigerant into the refrigerant circuit in a targeted manner by heating the reservoir in the event of an increased demand for refrigerant, in particular during simultaneous operation of both evaporators.
  • the refrigerant to be introduced into the evaporator is withdrawn from the condenser according to its needs for one or simultaneously at several sampling points.
  • 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 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 dimensions of the individual evaporators no longer exist, as was previously the case with refrigerated cabinets connected in series Evaporators usual, is determined by the expected ratio of the cooling capacities required in the individual subjects.
  • the evaporators can therefore be sized large in terms of optimum energy efficiency.
  • the evaporator of the cabinet by the invention can be independent of the refrigeration demand in the individual compartments design / dimension, open up the potential profitable multi-zone refrigeration produce whose components (especially evaporator) uniformly (modular) can be used in large quantities and here the Advantages of known from the prior art refrigeration furniture in terms of energy efficiency and controllability of the subjects opened.
  • 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 by one of the temperature sensor in at least one of the compartments of the refrigerator furniture a refrigeration demand, is set by the flow coefficient of the expansion valve so that the refrigerant flowing through it is preferably evaporated in the compartment in which the refrigeration demand was detected.
  • a refrigerated cabinet with two compartments was used.
  • 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 turns on a control line 14, the compressor 3 when in one of the subjects refrigeration demand is detected, and off again when no more refrigeration demand is detected.
  • the temperature control 10 controls in the signaling of a refrigeration demand in at least one compartment 12, 12 'via a control line 13, the expansion valve 5 to set depending on the detected refrigeration demand whose flow coefficient.
  • 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. Because of the Compressor 3 less refrigerant is sucked, 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.
  • 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.
  • Capillary tubes can be used in screens 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.
