    专利说明:

    The invention relates to a method for adjusting the temperature in a tempering container according to the preamble of claim 1. The invention further relates to a tempering, in particular for carrying out this method.
    Such tempering containers may be of different shape, e.g., rectangular or round, and provided for different purposes. In particular, it is also possible to comply with such temperature control standard-specific examination or measuring conditions, in particular for petroleum products. It is all about standard-compliant testing conditions, for example for the measurement of CFPP (Cold FilterPlugging Point), which determines the limit of the filterability of petroleum products.
    The term filterability limit or cold filter plugging point of the temperature limit value of the filterability designates a cold property of diesel fuels and fuel oil EL (extra light). This is the temperature in degrees Celsius at which a test filter is clogged under defined conditions by precipitated (n-) paraffins. In this method, the sample is cooled at a constant rate while passing through a test filter at defined intervals. Before reaching the filterability limit, crystals form at the so-called Cloud Point (CP), but still pass through the filter. If the crystals get too big, the filter clogs. Examined variables are the cloud point, in which the turbidity of the sample is visually examined by fog clouds of the precipitating paraffins, etc., and is irradiated at defined times, and the pour point test, in which an examination of the flowability of the temperature-controlled sample takes place. However, other investigations of tempered samples with regard to their physical properties, such as viscosity, rheological properties, etc., are conceivable using the method and the device according to the invention.
    Such measuring methods are usually based on exact standards which specify the temperature profiles to be maintained. For diesel CFPPs, for example, these are EN116, ASTM D 6371 and DIN EN 16329. These standards prescribe accurate temperature profiles for a tempering vessel, in this case a cooling chamber into which a glass vessel is spaced from the interior wall of the cooling chamber, which glass vessel is the sample to be tested contains. On the glass container, a lid sealing is placed, which transferred via a passage in the lid a defined Probenmengemittels a vacuum pump to a mark in a test volume. For the CFPP test, a screen of defined mesh size is mounted in the sample path to the test volume through which the sample is pumped. The temperature of the sample is measured, and at each temperature decrease by one degree, a sample of the sample forming
    Treibstoffes tried by means of the pump. At lower temperatures, the paraffin begins to flocculate in the diesel, suspended particles settle in the filter screen and block this. If, as a result, the filling time for the test volume exceeds a certain time or the fuel does not completely run back from the test volume into the glass container, this is considered to be the filterability limit according to CFPP. Normally, it is provided that the temperature in the temperature chamber is set to -34 ° C and the measurement of the sample takes place after the measurements at this temperature, the container is cooled to - 51 ° C and measured at this temperature and that finally takes place a cooling and measurement at -67 ° C. Cooling must be carried out quickly as required. Very tight times must be maintained for the cooling process of the tempering tank, and accordingly the cooling capacity must be sufficient to allow e.g. within a period of time, for example, within a period of time equal to 150 seconds of the temperature of the sample container enclosing the sample container. 17 degrees to cool. Typical cooling profiles for such cooling have the shape shown in Figure 3, with temperature T plotted over time t. It is readily possible to carry out other cooling courses or heating with the tempering container according to the invention.
    The Peltier technology competes with the conventional compressor and absorber cooling systems. Comparing the cost of the cooling capacity of these cooling systems, one concludes that Peltier elements are more expensive. The advantages of the Peltier technology must not be overlooked. For applications that require low cooling performance, Peltier elements require significantly less space. Controlling the performance of a Peltier element over the operating current is simple and accurate. By simply reversing the current direction, Peltier elements can be used both for heating and for cooling. Another advantage of Peltier cooling is an inexpensive external cooling supply for the countercooling of the elements.
    Due to the relatively low cooling performance of the Peltier elements, however, high dynamic performance requirements, such as for temperature control vessels, which are required in particular to fulfill the standards described above, are mostly unattainable. As long as large temperature differences have to be overcome in the shortest possible time, a Peltier element can not be used due to its limited cooling capacity at high temperature differences.
    Of course, there are single and multi-stage arrangements with Peltier elements which should increase the power, e.g. Peltier elements mounted on top of each other, as well as multi-level elements. However, Peltier elements are not suitable for rapid cooling steps, as required by standards in petroleum testing equipment. Such cooling is done with a Stirling or compressor cooler.
    Compressor cooler must be carried out but at least two stages, which makes it extremely expensive and large. The same applies to Stirling coolers.
    The main object of the invention is to make available for a sample container a tempering container, in particular for standard measuring methods, which is small and light and operates precisely and allows rapid temperature change. In particular, the tempering container or its sample receiving space should be able to be cooled rapidly to certain temperature levels and should be able to keep the temperature reached constant, while the sample in the sample glass or a measuring container assumes the temperature of the temperature container via heat convection and / or radiation.
    According to the invention, a method of the type mentioned is characterized by the features indicated in the characterizing part of claim 1. According to the invention, it is thus provided that a storage block of metallic material is attached to the surface of the Peltier element facing away from the container, ensuring that a further Peltier element or a Peltier element cascade is located on the rear surface of the storage block facing away from the Peltier element ensuring a heat transfer contact is made, that to change the temperature level of the container to a desired target temperature or toward that target temperature, the storage block is heated or cooled with the further Peltier element or the Peltier element cascade towards or beyond that target temperature, and in that, in order to realize a rapid temperature change in the container, the flow direction of flow of the Peltier element is switched such that it heats or cools the container in the direction of the desired target temperature, and d At the same time, it enables the passage of the amount of heat or quantity of refrigerant contained in the storage block through itself onto the container to enhance the heating or cooling of the Peltier element.
    Such a procedure is particularly useful for making measurements on petroleum products, preferably for determining the filterability of diesel fuels and domestic fuel oils. In particular, the regulations according to DIN EN 116 can be fulfilled with such a method.
    The invention makes use of the possibility of storing thermal energy with the help of Peltier elements and delivering it on demand. The essential thing is that the memory block is made of metal between the Peltier element and the further Peltier element. This metal block is sized so that it has sufficient
    Save amount of heat energy for the required application and this amount of heat can absorb and release quickly enough. As the material for such a heat storage, materials having high specific heat capacity and thermal conductivity, for example, aluminum, copper, brass, gold, silver, magnesium, etc., are well suited.
    It is noted in this connection that both high cooling rates and heating rates can be achieved with the method and device according to the invention. However, there are particular advantages in cooling the temperature of a sample receiving temperature control vessel.
    In the procedure according to the invention, the temperature in the
    It can be provided that the temperature control level in the container is not regulated or specifically influenced during the heating or cooling of the storage block, and is thus preferably kept constant or changed continuously.
    In order to achieve a sufficiently rapid and reliable temperature change in the tempering container, it is provided according to the invention that the heating or cooling of the storage block takes place above or below the desired target temperature to such an extent that the amount of heat or cold contained in the storage block and dischargeable to the container via the Peltier element is sufficient to achieve the desired target temperature of the container, preferably within a predetermined period of time. The required dimensioning of the amount of heat or cold is possible simply by taking into account the masses to be cooled and their specific heat, taking into account at the same time any environmental influences as well as heat convection and heat radiation. It will not be difficult for a person skilled in the art to choose the required materials and dimensions of the storage block and the tempering container in order to achieve a rapid transition of sufficient quantities of heat.
    In order to cope with all eventualities, it is envisaged that the storage capacity of the storage block for the storage of quantities of heat or refrigerant will be made larger than the amount of heat or refrigerant required for a desired temperature change of the container. By appropriate control of the Peltier element, the heat transfer from the storage block to the temperature control can be interrupted upon reaching a predetermined target temperature and then precisely controlled with this Peltier element, the target temperature or the temperature control are kept at this temperature or the temperature reached be changed.
    In order to have sufficient amounts of heat or cold available, it is useful if, when the container is cooled down to or towards the desired target temperature, the temperature of the storage block is lowered to a lower value than the target temperature and the Peltier is cooled to cool the container. Current flows through the element in such a way that it cools the container and allows it to flow through the amounts of cold contained in the storage block.
    Depending on the need, it is possible that, after reaching the desired target temperature in the container, this target temperature is kept constant or continuously varied with the Peltier element for a predetermined period of time, followed by at least one, preferably erratic, or linear heating or cooling to a desired target temperature. For efficient operation of the Peltier element and the further Peltier element and a rapid cooling of the storage block, it is advantageous if the Peltier element cascade or on its rear surface facing away from the container, preferably depending on the desired temperature setting in the storage block , heated or cooled. This procedure is supported when, when the container cools down, the Peltier element is switched to full power and switched to a constant temperature control mode just before or when the target temperature is reached.
    According to the invention, it is provided that the setting of the temperature is carried out for a tempering container, in which a measuring unit for determining temperature-dependent material parameters, in particular the viscous properties of samples, preferably of petroleum products, is arranged, which measuring unit is tempered or kept at a desired target temperature for the measurements.
    A tempering container according to the invention is characterized in that a storage block of metallic material is attached to the surface of the Peltier element facing away from the container, ensuring that a heat transfer contact faces away from the Peltier element and at the rear surface of the storage block facing away from the Peltier element a Peltier element cascade is mounted, that - to change the temperature level of the container to a target target temperature towards or towards that target temperature, a control unit for the flow of current through the Peltier element and the further Peltier element or the Peltier element cascade is provided which control unit the storage block with the further Peltier element or the Peltier element cascade can be heated or cooled in the direction of this target temperature or beyond, and that the control unit for the realization of a rapid temperature change in the container or its sample receiving space switches the current flow direction of the Peltier element such that it heats or cools the container towards the desired target temperature and thus simultaneously the transition of the amount of heat or cold contained in the storage block to the container to reinforce the Peltier element Heating or cooling releases.
    Because of the arrangement of the storage block between the Peltier element in thermal contact with the container outer wall and the further Peltier element on the rear side of the storage block facing away from the container, it is easily possible to rapidly cool the storage block and to supply a sufficient amount of heat sufficiently quickly to cool the tempering vessel to a desired temperature within a predetermined period of time. This temperature can be kept constant or changed in a predetermined manner to the Peltier element arranged on the container outer wall.
    It is possible to arrange a plurality of Peltier elements around the outer wall surface of the tempering tank. Advantageously, two to four Peltier elements are provided, which are arranged at equal intervals along the container circumference. Each of these Peltier elements is provided with its own memory block. In principle, a continuous memory block in the form of a storage ring could also be provided. Preferably, each Peltier element is associated with a further Peltier element on the rear surface of the storage block facing away from the container. If an annular storage block is used, a number of further Peltier elements or Peltier element cascades may also be provided which exceeds the number of Peltier elements. It is essential that the other Peltier elements can sufficiently cool down or heat up the memory block within a desired period of time.
    In order to support the function of the further Peltier elements, provision may be made for the Peltier element or the Peltier element cascade to be provided at its container-remote area with a heat exchanger with which the Peltier elements or the Peltier element cascade can be heated or cooled is.
    The Peltier elements are welded, soldered, glued or otherwise secured to the outer wall surface of the container. For containers with a curved outer surface, care must be taken to ensure that the flat Peltier elements are in good heat transfer contact with the container wall. This can e.g. by evenly executed areas of the container wall or by inserting heat-conducting intermediate pieces or filling materials into existing intermediate spaces. For operation, it is useful if, during the heating or cooling of the storage block, the control unit adjusts the temperature level in the container with the Peltier element and optionally keeps it constant or continuously changes it. For the temperature setting, it is expedient if in the interior of the Behälterbzw. the sample receiving space, a temperature measuring unit is arranged, which is connected to the control unit.
    The control unit actuates the Peltier elements at corresponding times and at the same time measures the temperature inside the temperature control tank. Depending on the measured temperature, the control of the direct current flowing through the Peltier elements or the reversal of the direction of current through which the Peltier elements flow is effected.
    According to the invention, it is possible, during the heating or cooling of the storage block, to control the temperature level in the container with the Peltier element and collect the excess energy at the beginning of such ramp in the storage block 4 and later to reach the target temperature in lower temperature ranges. Thus, the ramp is operated energy-optimized and it extremter target temperatures are possible.
    The tempering tank according to the invention is particularly well suited for the tempering of measuring units for determining the viscous properties of samples, preferably of petroleum products or for cooling of tempering containers in which such measuring units are used and maintained at a certain temperature and cooled or heated from this temperature towards a predetermined target temperature should.
    In the following we will explain the invention, for example, with reference to the drawings. 1 shows a basic structure of a device according to the invention. Fig. 2 shows schematically a measuring unit used in the tempering tank, as it is used for the CFPP measurement of petroleum products, in particular diesel. To the outer wall surface of a temperature control container 2, a Peltier element 3 is connected with heat transfer contact. This Peltier element 3 may be equipped with a countercooler 6. At the container 2 facing away from the surface of the Peltier element 3, a memory block 4 is attached. Connected to the reservoir-distal rear surface of the storage block 4 is another Peltier element 5 or a Peltier element cascade, which Peltier element 5 is equipped with a countercooling unit 6, which is supplied with fluid by a fluid cooling or heating unit 10. For the Peltier element 3, the memory block 4 can perform the function of the countercooler.
    Inside the tempering container 2 or its sample receiving space is a temperature measuring unit 11 whose output signal is applied to a control unit 7. The control unit 7 controls current regulators 8 and 9, wherein the current regulator 8 regulates the current direction and the current intensity of the direct current flowing through the Peltier element 3. The control unit 9 controls the current and the flow direction of the direct current through the further Peltier element 5.
    The cross section of the temperature control container 2 can be chosen arbitrarily or is adapted to the outer shape of the measuring unit 1 inserted into the container 2. The storage block 4 is usually formed by a cuboid metal block.
    The Peltier element 3 can, for. B. constantly be turned on to cool the Speicherblock4. At the same time, the further Peltier element 5 can be switched so that it also cools the storage block 4 and thus also lowers the temperature in the sample receiving space of the container 2. The Peltier element 3 can also generate as much heat or cold as is necessary to maintain the container 2 at a constant temperature and to cool the storage block 4 as much as possible, for which the Peltier element 3 is actually operated in heating circuit and the storage block 4 acts as countercooling.
    However, if a large temperature jump is required, the container-near-element 3 is traversed or switched in the reverse direction with electricity, so that the amount of cold of the memory block 4 located at a lower temperature leads into the container 2 and additionally actively cools the container 2. This results in the possibility of tempering the tempering body with high dynamics. Since the temperature of the container 2 by means of a single Peltier element, that is, the Peltier element 3, is adjustable, the control is very precisely possible.
    In this way, cooling rates of 20 degrees in 150 seconds are readily available.
    Starting a measurement of a sample, for example at room temperature, the cooling of the more preferably dimensioned further Peltier element 5 starts at full power. The memory block 4 cools down immediately. If a measurement in the container 2 at room temperature is desired, the container-near Peltier element 3 will be operated mainly in heating mode and the control unit 7 regulates the heat supply and discharge to and from the container 2 according to the temperature detected in the container by the at least one temperature sensor 11 2. In order to regulate the temperature quickly and accurately, several temperature sensors can also be installed in the container 2.
    In the case of cooling, the temperature of the storage block 4 before removal of the amount of refrigerant is substantially lower than the temperature in the container 2.
    In order to keep the temperature of the container 2 constant, the Peltier element 3 is switched to the heating mode and simultaneously heats the container 2 and protects it against the temperature prevailing in the storage block 4, which would otherwise cool the container 2 via the Peltier element 3.
    In a simple embodiment of the invention, the Peltier element 5 can always be operated with the same, preferably maximum, operating current and is switched on and off by the control and regulation unit 7 only at the beginning and end of the measurement.
    Using Peltier element cascades to get to lower temperatures, these can be switched on or off according to the desired temperature. Temperature jumps close to room temperature and also the keeping constant of the sample receiving space 15 of the container 2 at high temperatures require only one interlayer 5, whereas to achieve lower temperatures the Peltier element cascade is to be connected.
    If a temperature jump to lower temperatures is to be realized, the tank-side Peltier element 3 is switched into the cooling mode to full power with maximum operating current and the temperature of the memory block 4 is available for the temperature control of the sample receiving space 15. At the latest from reaching the desired target temperature sample receiving space 15, the Peltier element 3 again goes into the control mode and the operating current is regulated as a function of the achieved target temperature.
    Preferably, a control algorithm is selected which reduces the cooling already before reaching the target temperature in the container 2, in order to prevent a strong "oversteer" of the temperature values in the sample receiving chamber 15.
    Since Peltier elements can also be used as heating elements by reversing the current direction, the operation of the arrangement is in principle also possible as a heating device.
    Fig. 2 shows the principal measurement setup for the determination of the filterability limit of diesel fuels or fuel oil. In this test arrangement, a measuring unit 1 is used in the sample receiving space 15 of the tempering 2, the structure of which is specified by the corresponding standards EN 116, ASTM D 6371 or DIN EN 16329. Into a glass container 16, the sample liquid to be determined is filled. By means of a filter 12, the liquid is sucked into a test volume 14 by means of a pump 13, in particular a vacuum pump. This sucking and refluxing of the sample liquid at different temperatures from the sample receiving space 15 is carried out until sucking or refluxing of the sample liquid by precipitating paraffin particles can not be performed in a predetermined period of time. The essential part of the measuring process is the temperature control of the sample receiving chamber 15 of the container 2 or the adjustment of the temperature in the measuring unit 1, that is to say the temperature of the sample liquid. This setting is optimally achieved with the temperature control unit according to the invention or with the procedure according to the invention.
    FIG. 3 shows a tempering characteristic typical of such a measuring method. The tempering chamber 2 is cooled to -34 ° C in the course of the standard measurement preparation. The Peltier elements 3 and 5 cool at full power. Upon reaching this target temperature, the temperature of the tempering chamber 2 is kept constant with the Peltier element 3, while the Peltier element 5 further cools the storage element. Now, the glass container 16 with the sample to be examined or the entire measuring unit 1 are inserted into the sample receiving space 15 of the temperature-controlled container 2. The sample temperature is measured with a further temperature measuring unit 17 in the sample glass or a filter holder and, if necessary, transmitted to a control and evaluation unit 7 for the automatic test procedure. The measurement of the temperature-dependent property (CFPP) is now carried out according to standard from a sample temperature of 20 ° C every degree falls once. During this time, the temperature of the temperature-controlled container 2 is kept constant with the Peltier element 3 and the memory block 4 is further cooled with the further Peltier element 5. When the sample temperature reaches -20 ° C, the rapid cooling of the sample chamber starts at -51 ° C. The standard prescribed time for the temperature jump is achieved here by rapidly emptying the memory block 4. Other Temperautrampen and stages can be implemented in a comparable manner.
