    APPARATUS AND PROCEDURE FOR THERMAL COMPRESSION
    OF A MEDIUM This invention relates to a device for the thermal compression of a medium, comprising: - a housing; - a displacer arranged in the housing for delimiting in the housing: o a first space; o a second room; said displacer being movable in the housing between a first position in which the first space is minimal and the second space is maximal and a second position in which the first space is maximal and the second space is minimal; - an inlet for introducing the medium to be compressed into the first space; - an outlet for discharging the compressed medium from the first space; - cooling means which are thermally coupled or can be coupled to the first space; - heating means, which are thermally coupled or can be coupled to the second space; and - a first regenerator, with which the first space and the second space are mutually coupled or can be coupled, for driving the displacement movement of the displacer. Such devices are, for example, described and shown in US 3,413,815 A, US 2,157,229 A, WO 2014/023586 A1, WO 2014/202885 A1, WO 2017/068066 A1, and WO 2018/193188 A1.
    Such a device comprises heating means, which are thermally coupled to the second space, for heating medium in this second space.
    This device further comprises cooling means, which are thermally coupled to the first space, for cooling medium in this first space. The first space and the second space of the device are mutually coupled with the aid of a regenerator, so that the pressure in both spaces is equal. The inlet and outlet are fitted with check valves.
    The principle of operation of such a device is schematically depicted in Figure 2 and the compression cycle is shown in Figure 1.
    The displacer moves up and down and thereby respectively moves medium from the second space to the first space and vice versa from the first space to the second space.
    With the displacer in its first position, the medium in the second space is heated by the heating means. The medium moves through the regenerator from the second space to the first space and expands isochorically (from A1 to Bi). Heat from the medium is stored in the regenerator. The pressure drops in both chambers until the inlet pressure is reached.
    When the inlet pressure is reached, the non-return valve in the inlet opens and medium is sucked into the first space via this inlet (from Bi to C1). Then this non-return valve closes.
    The medium in the first space is cooled with the cooling means. Medium now moves from the first space to the second space and is isochorically compressed in the first space (from C to Di). Part of the heat of the medium that was stored in the regenerator is recovered. The pressure increases in the first space until the outlet pressure is reached.
    When the outlet pressure is reached, the check valve in the outlet opens and medium leaves the first high pressure space (from Di to A1).
    In practice, the coefficient of performance (COP) of such a device is much lower than the theoretically possible COP. This is because there are limitations to the heat that can be stored and recovered in the regenerator.
    The object of this invention is to increase the COP of such a device.
    This object is achieved by providing a device for the thermal compression of a medium, comprising: - a housing; - a displacer arranged in the housing for delimiting in the housing: o a first space; o a second room; said displacer being movable in the housing between a first position in which the first space is minimal and the second space is maximal and a second position in which the first space is maximal and the second space is minimal; - an inlet for introducing the medium to be compressed into the first space; - an outlet for discharging the compressed medium from the first space; - cooling means which are thermally coupled or can be coupled to the first space; - heating means, which are thermally coupled or can be coupled to the second space; - a first regenerator, with which the first space and the second space are mutually coupled or can be coupled, for driving the displacement movement of the displacer; and - a plurality of vessels, these vessels each being filled with a medium under a pressure, this pressure deviating stepwise for each of the vessels and wherein each of these vessels can be alternately coupled to a said space, so that when the displacer is in its first position state, to cascade fluid from the second space from the second space to the vessels and, when the displacer is in its second position, to cascade media from the vessels from the vessels to the second space. Using these vessels, part of the medium is moved to these vessels before the expansion of the medium and injected again just before the compression of the medium. This considerably increases the COP of the device. Transferring this mass also reduces the effective pressure increase by the regenerator during compression.
    With several such vessels a greater mass can be transferred than with a single vessel. The energy content is transferred in an efficient manner.
    The more vessels there are, the less pressure difference is realized in a tank during displacement. The larger the vessels are, the less pressure difference is realized in a tank during displacement. In terms of efficiency, however, there is a limit to the size of the vessels and the number of vessels.
    With multiple vessels, the pressure changes less in these vessels before and after moving. This pressure is also self-correcting in each vessel. When this pressure initially deviates from the optimum pressure in this vessel, less or more medium will be displaced until the optimum pressure is reached per vessel.
    With the aid of said vessels, the device can operate at a lower temperature for a comparable or even higher COP than with a comparable device according to the prior art.
    In contrast to the prior art, only a smaller portion of the medium will flow through the regenerator, so that the efficiency of the regenerator has a lesser impact on the efficiency of the entire device. If the effectiveness of the regenerator remains the same, the COP of such a device can be significantly increased by transferring fluid between the second space and the vessels.
    The temperature of the medium going into the first regenerator is more constant for such an apparatus with such vessels.
    This applies to the flow of medium from the second space to the first space as well as to the flow of medium from the first space to the second space. In a first preferred embodiment of a device according to the invention, the vessels can be alternately coupled to the second space in order to couple these vessels to a said space, this in order to gradually displace medium from the second space when the displacer is in its first position. from the second space to the vessels and, upon moving the displacer from its second position to its first position, to step fluid from the vessels from the vessels to the second space.
    Such an embodiment of a device according to the invention preferably comprises a controllable valve for mutually coupling the first space and the second space by means of this first regenerator.
    During the movement of medium between the second space and the vessels, this regenerator can then simply be closed off by means of this valve, so that medium cannot flow between the first space and the second space.
    In order to move the displacer, this valve can then be opened to interconnect the first space and the second space using this first regenerator.
    When such a device operates at comparable temperatures as with devices according to the state of the art, a valve from the turbo diesel technology can be used for this, for example.
    However, as indicated above, it is also possible to operate a device according to the invention at lower temperatures, with a comparable or even higher COP, whereby a cheaper valve can then be used.
    More specifically, the heating means can comprise per vessel a heating element which is thermally coupled or can be coupled to said vessel.
    By coupling the second space, the associated heating elements of the heating means are coupled to the second space.
    A device according to the invention, wherein the vessels can be coupled to the second space, further preferably comprises a valve per vessel for coupling this vessel to the second space.
    Even more preferably, such a device then comprises a second regenerator per vessel, coupled to or connectable to the second space and to which the respective valve of that vessel is coupled, for alternately coupling the vessels to the second space.
    With the aid of this second regenerator, the temperature of the medium in the vessels can be kept lower and the temperature of the medium flowing through the said valves, which are coupled to these vessels, is lower, so that cheaper valves can be used for this purpose.
    The heating means may further comprise a heating element per vessel for heating the respective second regenerator.
    In an alternative embodiment of a device according to the present invention, the vessels are not alternately connectable to the second space, but can be coupled to the first space, so that when the displacer is in its first position, medium from the second space is passed through the regenerator and the first space. cascade from the second space to the vessels and, when the displacer is in its second position, to cascade fluid from the vessels from the vessels to the first space so that it can be moved through the regenerator to the second space at moving the displacer from its second position to its first position.
    In this way a particularly cheap and simple variant of a device according to the invention is obtained.
    In this device, no said controllable valve is needed and no said second regenerators are required.
    With the aid of the barrels, however, no more work can be generated to run the machine. The temperature of the medium entering the regenerator is also less constant, because the pressure change in the spaces is much greater. This change in pressure causes a changing temperature of the medium being sucked in. Thus, the efficiency of the regenerator is lower. The mass passing through the first regenerator is in this case equal to the sum of the masses of the first generator and the second regenerators in an above-mentioned embodiment which is provided with said second regenerators.
    Such an alternative device according to the invention preferably furthermore comprises a valve per vessel for coupling this vessel to the first space. Said heating means of a device according to this invention can for instance comprise a gas burner. Preferably, these heating means comprise an electric heating element. In a specific embodiment of a device according to this invention, the housing and the displacer form a first compressor, the device comprises a second, similar compressor and the heating elements of the first compressor comprise a burner thermally coupled to the second space of the first compressor, and comprising an exhaust gas outlet, for exhausting exhaust gases from this burner, said exhaust gas outlet being coupled to the second compressor as a heating means. This second compressor can be in series or in parallel with the first compressor. Instead of realizing the displacement movement of the displacer by means of the first regenerator, it is also possible to provide the device, for example, with a motor for displacing this displacer via a drive shaft. This motor can for instance be used to start up the operation of the device, after which it can continue to operate automatically.
    Alternatively or additionally, the device may be provided with a generator which is drivable with the displacement movement of the displacer, via a drive shaft, so that the device can operate on the principle of a Stirling engine.
    The object of this invention is further also achieved by providing a heat pump comprising an above-described device according to this invention.
    In addition, the object of the present invention is also achieved by providing a method for thermally compressing a medium in a device for thermally compressing a medium, comprising: - a housing; - a displacer arranged in the housing for delimiting in the housing: o a first space; o a second room; said displacer being movable in the housing between a first position in which the first space is minimal and the second space is maximal and a second position in which the first space is maximal and the second space is minimal; - an inlet for introducing the medium to be compressed into the first space; - an outlet for discharging the compressed medium from the first space; - cooling means which are thermally coupled or can be coupled to the first space; - heating means, which are thermally coupled or can be coupled to the second space; and - a first regenerator, with which the first space and the second space are mutually coupled or can be coupled, for driving the displacement movement of the displacer;
    wherein this method comprises the following steps: - step a heating medium in the second space by means of the heating means for moving the displacer from the first position to the second position, wherein medium to be compressed is admitted into the first space via the inlet; - step b cooling medium in the first space by means of the cooling means for moving the displacer from the second position to the first position, wherein the compressed medium is discharged from the first space via the outlet.
    Furthermore, according to the invention: - when the displacer is in the first position, prior to step a, in a step c, vessels are each filled with medium under a pressure, this pressure for each of the vessels being lower than the pressure of medium in the second space, and this pressure differing for each of the vessels, coupled alternately with a said space, starting with the vessel with the medium under the highest pressure and ending with the vessel with the medium below the lowest pressure, to displace medium from the second space in steps from the second space to the vessels (this possibly via the first space and the regenerator), and - before or at step b, alternately step each of these vessels coupled to a said space starting with the vessel with the medium under the lowest pressure and ending with the vessel with the medium under the highest pressure, to move medium from the vessels step by step from the vessels to the second space (possibly via the ee). first room and the regenerator).
    This invention will now be further elucidated with reference to the following detailed description of an apparatus and a method according to this invention. The purpose of this description is only to provide illustrative examples and to indicate further advantages and particularities of this invention, and thus can in no way be interpreted as limiting the scope of the invention or of the patent rights claimed in the claims. In this detailed description reference is made to the accompanying drawings, in which: - Figure 1 represents the compression cycle of a prior art device, - Figure 2 shows the operating principle of a prior art device schematically presented in several steps; Figure 3 shows schematically a first embodiment of a device for the thermal compression of a medium according to the invention, with the displacer in its first position; Figure 4 is a schematic representation of the device of Figure 3, with the displacer in its second position; Figures 5 to 10 show schematically the different steps for moving medium from the second space of the device of Figure 3 to the five vessels from this device, Figure 11 shows the compression cycle of the device of Figure 3; Figures 12 to 17 show the operating principle of the device of Figure 3 schematically in several steps; Figure 18 shows schematically a second embodiment of a device for the thermal compression of a medium according to the invention, with the displacer in its first position.
    The devices (1) shown are devices (1) for the thermal compression of supercritical CO 2 . Similar devices (1) can also be provided for the thermal compression of other media, such as, for example, gases for diving cylinders, etc.
    The illustrated devices (1) according to the present invention comprise a housing (2) and a displacer (3) arranged in the housing (2) for insertion into the housing.
    (2) defining a first space (4) and a second space (5). The displacer (3) is thereby displaceable in the housing (2) between a first position in which the first space (4) is minimal and the second space (5) is maximal (as shown in figure 3) and a second position in which the first space is space (4) is maximum and the second space (5) is minimum (as shown in Figures 4 and 18).
    The displacer (3) is connected to a plunger (drive shaft) (29) which extends through the housing (2) and is coupleable to a motor, for initiating the displacement movement of the displacer (3). This motor can also be designed as a generator.
    In the device (1) shown, the first space (4) is arranged at the bottom of the housing (2) and the second space (5) is located at the top of the housing. An inverted arrangement is also possible, however, analogous to US 2,157,229 A. The displacer (3) is movable up and down in the figures, but another displacement movement is also possible, such as, for example, a displacement movement analogous to US 3,413,815 A.
    Heating means are thermally coupled to the second space (5) for heating medium in this second space (5). Cooling means are thermally coupled to the first space (4) for cooling medium in this first space (4). These heating means and cooling means are not shown, but can, for example, be elaborated in a comparable manner as in the prior art.
    The first space (4) and the second space (5) of the device (1) are mutually coupled by means of a first regenerator (15), so that the pressure in both spaces (4, 5) is equal.
    An inlet (6) to the first space (4) is provided with a non-return valve (20), for admitting medium to be compressed into the first space (4). An outlet (7) from the first space (4) is also provided with a non-return valve (21), this for exhausting compressed medium from the first space (5).
    Similar parts of this device (1) as in the prior art can be elaborated in similar ways, so that they will not be discussed in more detail. In the following, only the deviating parts and the deviating operation compared to the prior art will be discussed in more detail.
    In addition to these parts, this device (1) also comprises several vessels (8, 9, 10, 11, 12). These vessels (8, 9, 10, 11, 12) are each filled with supercritical CO: under a pressure, this pressure deviating stepwise for each of the vessels (8, 9, 10, 11, 12), as can be seen in Figures 5 to 10. Each of these vessels (8, 9, 10, 11, 12) is in the first illustrated embodiment (Figures 3 and 4) connected to the second space (5) by ducts (27). In the second illustrated embodiment (Figure 18), these vessels (8, 9, 10, 11, 12) are connected to the first space (4). A valve (22, 23, 24, 25, 26) is arranged in these pipes (27) per vessel (8, 9, 10, 11, 12) so that the vessels (8, 9, 10, 11, 12) alternate be connectable to the second space (5) in the first illustrated embodiment and to the first space (4) in the second illustrated embodiment. For each of these valves (22, 23, 24, 25, 26), a second regenerator (17) can be arranged per vessel (8, 9, 10, 11, 12) as shown in the first embodiment, so that the temperature of medium flowing through the valves (22, 23, 24, 25, 26) can be kept limited.
    The illustrated devices (1) comprise five vessels (8, 9, 10, 11, 12). In alternative devices (1), more or fewer vessels (8, 9, 10, 11, 12) can also be provided. Furthermore, in the first embodiment shown, a controllable valve (16) is provided in the regenerator (15), with which the coupling between the first space (4) and the second space (5) can be opened and closed. Instead of providing this controllable valve (16), the displacer (3) can also be driven with a motor to move it without having to move medium through the regenerator (15).
    With the displacer (3) in its first position and the valve (16) in the regenerator (15) closed, the second space (5) in the first illustrated embodiment is first coupled alternately with the vessels (8, 9, 10, 11 , 12) (from A to B in Figure 11) (Figures 5 to 10; Figures 12-13), by alternately opening and closing the respective valves (22, 23, 24, 25, 26), starting with the vessel (8) with CO: at the highest pressure (Figures 5-6) and ending with the vessel (12) at the lowest pressure (Figures 9-10). Each time, the pressure in these vessels (8, 9, 10, 11, 12) rises to the pressure in the second space (5), the pressure in the second space (5) decreasing stepwise.
    The CO: expands isentropically.
    After disconnecting the second space (5) from the last vessel (12), the valve (16) in the regenerator (15) is opened.
    Considering the transfer of CO: from the second space (5) to the vessels (8, 9, 10, 11, 12) the pressure in the second space (5) has become lower than in the first space (4), the displacer (3) partially upwards (from B to C in Figure 11) (Figures 13-14). The CO: in the second space (5) is heated by the heating means, moves through the regenerator (15) from the second space (5) to the first space (4) and expands isochorically.
    The displacer (3) moves upwards (Figure 14-15). Heat from the CO: is stored in the regenerator (15). The pressure drops in the first space (4) until the inlet pressure is reached.
    When the inlet pressure is reached, the non-return valve (20) in the inlet (6) opens and medium is sucked into the first space (4) via this inlet (6) (from C to Din figure 11) (figures 14-15). Then this non-return valve (20) closes. The valve (16) in the regenerator (15) is closed.
    The second space (5) is alternately coupled to the vessels (8, 9, 10, 11, 12) (from D to E in Figure 11) (Figures 10 to 5; Figures 15-16), by alternately opening and closing of the respective valves (22, 23, 24, 25, 26), starting with the vessel (12) with CO: under the lowest pressure (Figures 10-9) and ending with the vessel (8) under the highest pressure ( figures 6-5). The pressure in these vessels (8, 9, 10, 11, 12) always falls to the pressure in the second space (5), the pressure in the second space (5) increasing stepwise.
    The displacer (3) moves downwards.
    Thereafter, the valve (16) in the regenerator (15) is opened.
    The medium in the first space (4) is cooled with the cooling means (14) and by expansion.
    Medium moves from the first space (4) to the second space (5) and is isochorically compressed in the first space (4) (from E to F in Figure 11) (Figures 16-17). Part of the heat of the medium stored in the regenerator (15) is recovered. The pressure increases in the first space (4) until the outlet pressure is reached.
    When the outlet pressure is reached, the check valve (21) in the outlet (7) opens and fluid exits the first high pressure space (4) (from F to A in Figure 11) (Figures 17-12).
    The valve (16) in the regenerator (15) is closed back and the cycle is allowed to repeat.
    In the second illustrated embodiment, with the displacer (3) in its first position, the first space (4) is first alternately coupled to the vessels (8, 9, 10, 11, 12), by alternately opening and closing the respective valves (22, 23, 24, 25, 26), starting with the vessel (8) with CO: at the highest pressure and ending with the vessel (12) at the lowest pressure. The CO: from the second space (5) flows via the regenerator (15) and the first space (4) to the vessels (8, 9, 10, 11, 12). Each time, the pressure in these vessels (8, 9, 10, 11, 12) rises to the pressure in the second space (5), the pressure in the second space (5) decreasing stepwise. The CO: expands isentropically. Considering the transfer of CO: from the second space (5) to the vessels (8, 9, 10, 11, 12) the pressure in the second space (5) has become lower than in the first space (4), the displacer (3) partially upwards. The CO: in the second space (5) is heated by the heating means, moves through the regenerator (15) from the second space (5) to the first space (4) and expands isochorically. The displacer (3) moves upwards. Heat - from the CO: is stored in the regenerator (15). The pressure drops in the first space (4) until the inlet pressure is reached. When the inlet pressure has been reached, the non-return valve (20) in the inlet (6) opens and medium is isobard into the first space (4) via this inlet (6). Then this non-return valve (20) closes.
    The first space (4) is then coupled alternately with the vessels (8, 9, 10, 11, 12), starting with the vessel (12) containing CO: under the lowest pressure and ending with the vessel (8) below the highest pressure. The pressure in these vessels (8, 9, 10, 11, 12) always falls to the pressure in the second space (5), the pressure in the second space (5) increasing stepwise. The displacer (3) moves downwards.
    The medium in the first space (4) is cooled with the cooling means (14) and by expansion. Medium moves from the first space (4) to the second space (5) and is isochorically compressed in the first space (4). Part of the heat of the medium stored in the regenerator (15) is recovered. The pressure increases in the first space (4) until the outlet pressure is reached.
    When the outlet pressure is reached, the check valve (21) in the outlet (7) opens and medium leaves the first space (4) at high pressure.
