Definitions
- Refrigeration circuit with a sublimator for carbon dioxide as
- the conventional cold vapor process with other refrigerants usually runs in the two-phase region of the gaseous and liquid state of the refrigerant.
- the pressure in the circuit In order to achieve temperatures below -56 ° C with C0 2 as the refrigerant, the pressure in the circuit must be lowered below the triple point, whereby at least partially carbon dioxide must be used as a solid.
- the usable temperature level can be made accessible up to about -78 ° C or even lower.
- the evaporator becomes sublimator when the sublimation line falls below the tripin pressure. Due to the sublimation of the carbon dioxide from the solid into the gaseous phase, the useful cooling is created while absorbing heat.
- DE 27 48 796 A1 discloses a method and a device for cooling materials using stored, cryogenic cooling, in particular using carbon dioxide as a refrigerant.
- DE 30 04 114 A1 discloses a process for producing low temperatures using carbon dioxide as the refrigerant. It addresses the problem of solid agglomeration of solid carbon dioxide by suspending the solid carbon dioxide particles in a non-freezing liquid and circulating it as a suspension.
- the object of the invention is therefore to provide a method for operating a circuit with a sublimator with carbon dioxide as a refrigerant and a device available that largely prevents or reduces the problem of forming blockages or deposits of solid carbon dioxide in the sublimator.
- the object is achieved by an article according to the independent claims. Further developments are specified in the dependent claims.
- the object of the invention is achieved in particular by a method for operating a refrigeration cycle with a sublimator for carbon dioxide as a refrigerant, wherein the refrigeration cycle is operated below the triple point.
- the special feature is that in the sublimator the sublimation line of the carbon dioxide is exceeded below the triple point.
- a cleaning of the sublimator of blockages with solid C0 2 or deposits of solid C0 2 by a targeted reduction of the cross section of the refrigerant path after the sublimator.
- the pressure in the sublimator is raised above the trip pressure and the solid carbon dioxide is converted into liquid carbon dioxide.
- the blockages and deposits of solid C0 2 are dissolved.
- the refrigerant path is at least partially increased again and distributed the liquid carbon dioxide in the sublimator by the pressure drop and converted back into solid or gaseous carbon dioxide after falling below the Tripeiyakes.
- the change in the cross section of the refrigerant path is carried out in dependence on control or control signals.
- the invention is advantageously further developed in that the sublimator is filled discontinuously with liquid carbon dioxide above the tripin pressure. By subsequent rapid lowering of the pressure below the Tripeiyakes solid and gaseous carbon dioxide is produced in a uniform distribution in the sublimator.
- the filling of the sublimator with liquid carbon dioxide is preferably carried out when the cleaning of the sublimator of solid carbon dioxide is carried out by cross-sectional constriction after the sublimator.
- the reduction of the cross section of the refrigerant path is carried out until the refrigerant path is completely closed, in which case a pressure increase associated with the liquefaction of the solid carbon dioxide can be achieved.
- the reduction of the cross section of the refrigerant path takes place as a function of a pressure loss limit value above the sublimator.
- the reduction of the cross section of the refrigerant path takes place as a function of the compressor suction pressure.
- a further advantage is the reduction of the refrigerant path as a function of a limit value for the temperature spread, which can be measured on the air side or on the secondary side via the sublimator.
- the reduction of the cross section of the refrigerant path can be determined as a function of a limit value for the temperature spread on the refrigerant side.
- the reduction of the cross section of the refrigerant path after a predetermined time interval in the manner of a control results from the fact that the reduction of the cross section of the Kältem ittelpfades in response to a combination of several of the aforementioned control and regulation signals.
- the reduction of the cross section of the refrigerant path can be carried out according to an advantageous embodiment of the invention between 5 and 30 seconds.
- the object of the invention is further achieved by a device with which the above-described method can be realized, which is characterized in that a shut-off device for changing the cross section of the refrigerant path is arranged after the sublimator in the refrigerant path. Furthermore, at least one sensor and a control and regulating device for controlling and regulating the shut-off device are provided for regulation and control.
- An advantage of the invention is in particular that it is now possible to dissolve solid carbon dioxide deposits in the designed as a sublimator heat exchanger by a cleaning procedure during operation or distribute. By temporally minimal delays of the dissolution process, a substantially continuous cycle operation of a carbon dioxide cycle can be ensured below the triple point with constant heat transfer performance.
- the sublimator is continuously supplied with carbon dioxide from the circulation by the upstream throttling element of the circuit.
- the short-term supply of the sublimator with C0 2 located at a higher pressure can also be realized from another reservoir, for example from other plant zones which, due to the process, are at a higher pressure level.
- a shut-off device for example in the form of a solenoid valve, after the heat exchanger, the pressure in the sublimator rises. If the pressure temporarily exceeds the trip pressure of the carbon dioxide of 5.18 bar, all carbon dioxide solids components dissolve immediately due to physical reasons and liquid carbon dioxide forms. Thereafter, the shut-off can be completely or partially reopened, whereby the liquid esters are distributed by the pressure drop and again converted back to solid or gaseous C0 2 and fed to the main stream.
- the shut-off device after the sublimator should just be opened so far that the pressure in the sublimator is still above the trip pressure during the filling.
- the sublimator is filled with refrigerant, similar to a conventional evaporator. After sufficient filling the shut-off device is selectively opened after the sublimator and lowered the pressure in the sublimator below the Tripei réellees. This forms in the sublimator a preferably homogeneous distribution of solid and gaseous C0 2 , which can be used for cooling.
- the cleaning procedure preferably takes only a few seconds, so that the effect of the short-term increase in temperature and pressure on the continuous provision of cooling in the sublimator is extremely low.
- Control technology is the start signal for the cleaning procedure, ie the operation of the shut-off device for reducing or blocking the cross-section of the refrigerant path, by different sizes alone or in combination triggered.
- Another advantage of the invention is that with the downstream Shut-off the pressure level in the sublimator can be kept until full filling with preferably liquid C0 2, the pressure above the triple conditions and then a rapid pressure drop below the triple conditions is possible.
- the sublimator is then ideally filled evenly with solid and gaseous C0 2 .
- control and regulating device is regulated via a pressure loss limit value above the sublimator.
- Further control and regulating parameters are the triggering of the reduction of the cross section of the refrigerant path, the compressor suction pressure, a limit for the temperature spread or the outlet temperature on the air side, as well as a limit value for the temperature spread or the outlet temperature on the refrigerant side and the absolute pressure at different points in the sublimator itself.
- the cleaning procedure can be triggered, for example, after a predetermined time interval.
- the cleaning procedure has a special technical condition, especially with sublimators in multi-pass design.
- the cleaning procedure is also advantageous in the case of a passable design of the heat exchanger as a sublimator.
- the concept of the invention consists in briefly triggering an increase in pressure above the tripeid pressure of carbon dioxide by means of an additional shut-off device in the flow direction downstream of the sublimator according to predetermined control and / or control signals and dissolving or distributing carbon dioxide solids deposits formed thereby.
- the short-term desired increase in pressure can alternatively or cumulatively by supplying C0 2 from a reservoir with higher Pressure level done.
- An advantage of the arrangement of the shut-off device in the flow direction after the sublimator is additionally that the pressure level when filling the sublimator is still slightly above the Tripeiyakes and only then lowered below the Tripei réellees.
- Fig. 2 Section of a schematic diagram of a circuit with
- Fig. 4 Scheme two-stage process.
- a phase diagram for carbon dioxide is shown schematically.
- the physical state of C02 depends not only on its temperature but also on the pressure.
- all three phases are fixed (f), liquid (fl) and gaseous (g) in equilibrium.
- the tripapulse pressure is 581 kPa and thus well above atmospheric pressure, the associated temperature is approximately - 56 ° C.
- C0 2 can be present under normal conditions only as gas or in solid state as dry ice.
- dry ice passes directly from solid (f) to gaseous (g), sublimating.
- the line in the phase diagram which marks the transition from the solid to the liquid state, is also called the sublimation line.
- FIG. 2 shows a section of a refrigeration system with a sublimator 1 for producing lower temperatures with carbon dioxide as the refrigerant.
- the sublimator 1 is a heat exchanger, which is specially designed to use the sublimation heat in the transition from solid carbon dioxide to gaseous carbon dioxide.
- the heat exchanger shown is designed multi-pass, so that there are several parallel channels within the refrigerant path through the sublimator 1 therethrough.
- the refrigerant path 2 thus branches at the input into the sublimator 1 and is recombined at the output of the sublimator 1.
- the expansion element 4 for producing the solid carbon dioxide is arranged in front of the sublimator 1 in the flow path 2 and leads to the formation of solid carbon dioxide in the sublimator 1.
- FIG. 2 shows an optionally usable bypass 6 with throttling device, via which carbon dioxide can be fed to the sublimator 1 at a pressure above the tripane pressure in order to accelerate the process of pressure increase in the sublimator 1.
- a subsequent pressure reduction leads to a conversion of the liquid carbon dioxide into gaseous and solid carbon dioxide.
- Fig. 2 various sensors 5 are schematically indicated in the circuit, which in each case state and process variables of various kinds to the control and regulating device, whereupon by the control device, a corresponding control or control signal to the shut-off device 3 for Close or open the same is transmitted.
- Fig. 3 is a single-stage refrigeration system with internal heat exchanger 7 is shown schematically.
- the refrigeration system consists in addition to the already designated in Fig. 2 components in the flow direction of the refrigerant compressor components 9, a heat exchanger 8 for heat dissipation, which is referred to depending on the function and condition of the refrigerant as a recooler, gas cooler or condenser and the inner heat exchanger. 7
- bypass 6 taps the already present in the circulation higher pressure level on the high pressure side directly.
- the throttle body in the bypass 6 can preferably be designed so that it allows a release of the opening cross-section only to just above the Tripeiyakes. This allows the components on the low pressure side of the circuit to be additionally protected against excessive pressure increase.
- the required control and regulation of the throttle body in the bypass 6 can preferably also be effected by the relevant state and process variables about the sublimator 1.
- a two-stage refrigeration system with internal heat exchanger 7 is shown schematically. Accordingly, an additional compressor 9, an additional expansion element 4 for the high-pressure stage, a recooler 8 at medium pressure level and a medium-pressure vessel 10 are provided in the circuit for the compression to medium pressure.
- Another special feature is that two bypasses 6 are provided for the supply of carbon dioxide in the sublimator 1, wherein a bypass 6 from the medium-pressure level and a bypass 6 from the high-pressure level with the sublimator 1 is connected.
- the system represents a possible, particularly efficient variant for a sublimation cycle with C0 2 .
