Definitions

  • the present invention relates to a single-circuit refrigeration device with two temperature zones, which are cooled by in a refrigerant circuit in series in series evaporator.
  • the two evaporators are connected in the refrigerant circuit without significant flow resistance between them, set in both about the same pressures and pressures each corresponding evaporation temperatures. These evaporation temperatures must be lower than the temperature of the coldest temperature zone. Accordingly, the temperature difference between the evaporators and the warmer of the two temperature zones is large.
  • a single-circuit refrigerating appliance in which a throttle section is inserted in a refrigerant circuit between the first and second evaporators, which ensures different pressures and consequently also different evaporation temperatures in the two evaporators.
  • the cooling capacity of both evaporators can be distributed according to the refrigeration demand, and the compressor can run continuously. Start-stop losses and unnecessary temperature fluctuations can thus be avoided, which improves the energy efficiency of the cooling.
  • a common measure for improving the energy efficiency of a refrigerator is to connect a capillary extending from the condenser to the evaporator, and a suction line leading from the outlet of the evaporator to the compressor to a heat exchanger, so that the refrigerant, which in the Capillary to the evaporator flows, cooled and the extracted from the evaporator refrigerant vapor is warmed up.
  • the mass flow rate of the capillary becomes higher than that of the compressor, with the result that liquid refrigerant accumulated in front of the capillary flows off faster than can be reproduced in the condenser.
  • the mass flow rate decreases sharply, the pressure in the condenser increases, so that more liquid refrigerant is replicated and soon flows again with high mass flow rate through the capillary.
  • the constant change between liquid refrigerant and steam or between high and low mass flow in the capillary leads to disturbing operating noise.
  • the object of the present invention is to provide a single-circuit refrigeration device with evaporators which can be operated at different pressures, in which the noise emission is reduced without impairing the energy efficiency.
  • the object is achieved by, in a single-circuit refrigeration device with a refrigerant circuit, in which are connected in series between a pressure port and a suction port of a compressor in sequence:
  • a downstream portion of the suction pipe is connected to the first throttle portion to a first heat exchanger, and an upstream portion of the suction pipe is connected to the second throttle portion to a second heat exchanger.
  • the refrigerant vapor in the suction line when it reaches the downstream portion, already preheated by the second heat exchanger to a temperature which is at most slightly below the evaporation temperature in the first evaporator.
  • a cooling of the refrigerant in the first throttle section to a temperature below the evaporation temperature of the first evaporator can be excluded.
  • partial evaporation of the refrigerant in the first throttle portion remains possible, and when the vapor generated in the first throttle portion continuously restricts its mass flow rate, noise-intensive fluctuations as described above can be prevented.
  • the second throttle portion may include a conduit portion which is connected to the upstream portion of the suction conduit by an adhesive, in particular by an adhesive tape.
  • the second throttle section may comprise a line section which is guided within the upstream section of the suction line.
  • the second throttle portion includes a conduit portion wound around the upstream portion of the suction conduit.
  • the line section of the second throttle section may be formed as a capillary.
  • the second throttle section has an adjustable flow conductance, by means of which different pressure differences and thus also different temperature ratios between the first and second evaporators can be set.
  • the second throttle section for adjusting the Strömungsleitwerts include a controllable expansion valve.
  • the expansion valve may be essentially solely responsible for the pressure drop between the first and second evaporators; but it can also be connected in series with a capillary, so that the pressure drop is composed of a fixed contribution of the capillary and a variable contribution of the expansion valve.
  • FIG. 1 shows a schematic representation of the refrigerant circuit of a refrigeration device according to the invention
  • FIG. 2 shows a schematic section through the housing of the refrigeration device.
  • FIG. 3 shows a first embodiment of a heat exchanger of the refrigeration device
  • Fig. 5 shows a third embodiment of the heat exchanger.
  • the refrigerant circuit shown in Fig. 1 comprises a speed-controlled compressor 1 with a pressure port 2 and a suction port 3.
  • a starting from the pressure port 2 refrigerant pipe 4 extends in the direction of circulation of the refrigerant first via a condenser 5 and a first throttle section 6, here in the usual way Capillary line 7 realized to a first evaporator 8.
  • a second throttle section 9 with adjustable Strömungsleitwert located on the refrigerant line 4 between an outlet port of the first evaporator 8 and an inlet port of a second evaporator 10.
  • a suction line 1 1 extends from an outlet port of the evaporator 10th to the suction port 3 of the compressor. 1
  • the evaporator 8 located upstream along the refrigerant line 4 cools a standard refrigerating compartment 16 and the downstream evaporator 10 cools a freezer compartment 17 of a household refrigerating appliance.
  • the second throttle section 9 comprises a conduit section 18 and a controllable expansion valve 22 connected in series with the conduit section 18.
  • the conduit section 18 may have a similar conduit cross-section as the refrigerant conduit of the evaporator 6, but may also be like the first Throttle section 6 may be formed by a capillary.
  • the conduit portion 18 formed as a capillary is long enough to ensure a pressure drop between the evaporators 8, 10, which corresponds to a difference in the evaporation temperatures of the evaporators 8, 10 of several ° C, even if the expansion valve 22 is opened to the maximum.
  • An upstream portion 12 of the suction pipe 11 is thermally connected to the second throttle portion 9 to form a heat exchanger 14; a downstream section 13 of the suction line 1 1 forms a further heat exchanger 15 together with the first throttle section. 6
  • a temperature sensor 19 and 20 is arranged at each of the compartments 16, 17, a temperature sensor 19 and 20 is arranged.
  • the temperature sensors 19, 20 are connected to a control unit 21, which controls the speed of the compressor 1 and the opening degree of the expansion valve 22 by comparing the temperatures reported by the temperature sensors 19, 20 with set by a user set temperatures of the compartments 16, 17. If, for example, the temperature sensor 19 indicates cooling demand in the normal cooling compartment 16, ie if the temperature in the normal cooling compartment 16 is at the upper edge of a tolerance interval around the user set target temperature, then the control unit 21 checks the temperature of the freezing compartment 17.
  • the control unit 21 increases the speed of the compressor 1, so that both compartments 16, 17 are cooled more; is the other hand Temperature of the freezer compartment 17 in the lower part of the tolerance interval, so that a more intense cooling would cause the tolerance interval is left down, then the control unit increments the opening degree of the second throttle section 9, so that the pressure in the evaporator 8 decreases.
  • the overall cooling performance remains substantially unchanged, but it increases the proportion of the total cooling capacity, which is attributable to the normal cooling compartment 16, so that it can be cooled, without causing at the same time to a supercooling of the freezer compartment 17.
  • the control unit 21 determines whether the speed of the compressor 1 is being incremented to more strongly cool both compartments 16, 17, or whether the degree of opening of the second throttle section 9 is reduced in order to increase the cost of the freezer compartment part of the total cooling power.
  • the series connection of the two heat exchangers 14, 15 along the suction line 1 1 causes the refrigerant vapor extracted from the evaporator 10 of the freezer compartment 17 already has a temperature at the heat exchanger 15, which corresponds approximately to the evaporation temperature in the evaporator 8.
  • the evaporation in the capillary 7 of the first throttle section 6 is therefore not completely suppressed, so that there is always a small amount of vapor in the capillary 7 and limits the mass flow rate.
  • both of an adhesive tape 23, preferably a good heat-conducting aluminum adhesive tape are looped around, as outlined in Fig. 3.
  • the line section 18 extends in the interior of the suction line 1 first
  • the pipe section 18 may be wound around the upstream section 12 of the suction pipe 11 to form the heat exchanger 14.
  • the expansion valve 22 may be formed according to a non-illustrated variant by a directional control valve and a plurality of capillary sections of different lengths, one of which in each case is coupled through the directional control valve in the refrigerant circuit.
