- ERSATZBLA ⁇ (RULE 26 delimit at least one partial volume with a minimal size largely without overlap with the comparable and in some cases induce movements by elements of the control system that act on it, by means of which the ratio of this partial volume to this working volume is either increased or decreased in the time periods of the periodically running thermodynamic cycle, during which this working volume is only changed in size to a smaller extent and depending on the pressure of the working fluid in this working volume at least one specific valve whose opening and closing time decisively influences the thermodynamic cycle and which can delimit this working volume against at least one external space which fills up is un fluctuating with at least one working medium with partially different fluctuations in this working volume relative to the periodic pressure change during these time periods pressure, the control system or the flow pressure is predominantly kept open (in the time periods characterized above) and flows through, which (valves) is kept closed during other time periods running between these time periods, in which the pressure of the working fluid in this working volume by the shift of the above or other components or components by the control system and the resulting change in the average temperature of the working fluid in
- Working volume through the mechanical compression device either increases or decreases and the ratio of each sub-volume as defined above to this working volume is changed only to a significantly lesser extent, whereby during a time interval that is much longer in relation to the period, either a thermal energy intake or release of at least one substance of a continuous or periodic swelling and declining mass flow takes place at a sliding temperature or at several temperature levels and in this working volume at least one working medium acts at least partially as a working fluid which goes through the periodic thermodynamic cycle.
- the method according to the invention runs in a device according to the invention for
- Compression device e.g. one or more pistons, liquid pistons or membranes, and optionally at least one liquid interface or no at least one working volume filled with working fluid is largely limited, in which • in each case at least two separable from the working fluid in one
- Working volume through the mechanical compression device either increases or decreases and the ratio of each sub-volume as defined above to this working volume is changed only to a significantly lesser extent, whereby during a time interval that is much longer in relation to the period, either a thermal energy intake or release of at least one substance of a continuous or periodic swelling and declining mass flow takes place at a sliding temperature or at several temperature levels and in this working volume at least one working medium acts at least partially as a working fluid which goes through the periodic thermodynamic cycle.
- the entire cyclic process in a working volume can be assigned several circular processes running in parallel between two heat reservoirs with constant temperatures, viewed with reasonable idealization.
- Each heat reservoir of these cyclic processes can be assigned to a partial volume of the working volume which is filled with working fluid and as defined above.
- At least one substance of a continuous or periodically increasing and decreasing mass flow is heated or cooled either by the absorption or release of thermal energy at a lower temperature difference relative to the overall temperature change when it comes into contact with the hotter or colder heat reservoirs of these cycle processes, the phase or can transform chemical composition.
- At least one substance of a continuous or periodically swelling and declining mass flow is supplied with thermal energy at a sliding temperature or at several temperature levels.
- the principles can change due to the temperature change over a large temperature interval
- the thermal energy can be very effective and inexpensive with a sensitive memory that has a large surface such as a gravel fill, can be exchanged when working fluid flows through.
- the heat energy transport can be achieved by moving a capacitive working medium, e.g. Air.
- thermal energy when a gas mixture is vaporized, thermal energy must be supplied over a temperature interval or at several temperatures.
- the preamble and the main claim of the patent cited in sections include a restriction to regenerative work or heating machines, in which the work volume available to the working fluid is increased by a flowing through, rigidly connected structure of regenerator, cooler and heater as in the known Stirling engines is divided into only two periodically changeable partial volumes.
- the working gas runs through a cycle between two heat reservoirs, from which thermal energy is taken or supplied at constant temperatures.
- thermal energy that is taken from the machine above Tk can only have been transported through irreversibility and must come from the heater, since there is no relevant cycle in the machine, the thermal energy from the temperature level of the coldest part volume of the gas-filled working volume to the higher temperature level pumps.
- the mechanical work supplied (used) or given (won) during a period of the entire cycle to balance the energy balance is largely directly transferred from a storage space when at least a certain amount of at least one fluid substance is transferred moved to another storage space with different pressure.
- the cited patent is compared to the more abstract formulation of the task chosen above. limited to cooling or heating a heating or cooling medium through thermal contact with heat exchangers of a regenerative work or heat engine.
- Fresh air can flow into the working volume through one of the valves at atmospheric pressure, which can result in decisive synergy effects in some applications.
- hot air is taken up in a working volume and blown out as cooler air into a room with higher pressure, some of the heat energy released when the air is cooled being taken up by the cooler.
- hot fresh air at atmospheric pressure from exhaust gases
- Temperature interval (eg 200 ° C to 500 ° C) can be used to achieve a higher final temperature of the working fluid when heated in the collector's absorber with relatively little effort.

Since the gas in the entire working volume is in direct contact with heat transfer surfaces in this period of time to large heat capacities, which are necessary for the thermodynamic cycle and due to their special movement, the gas is not moved relative to it, this period of the cycle can be described by an isothermal expansion the same formulas apply to the exchanged thermal energy or work as for the time period abc

- this entropy transformer may be easier to set up, since no heat exchanger (e.g. car cooler) is necessary.
- this construction can also be operated in such a way that lukewarm gas with higher pressure is pressed into the working volume by a turbine and thereby the flow direction but not the periodic sequence of movements (see Fig. 4, Fig. 5, Fig. 6) is changed and hot and cold gas flow out of the working volume at a lower pressure.
- the gas may by a Entropietransformator 2 working volumes under the cooling water temperature T k are cooled.
- the driven fan 14 is replaced by one of the devices described above with the effect of a gas compressor, the hot gas being absorbed by the working volume which can be assigned to the gas compressor and, at higher pressure, by the outlet valve 4 this working volume is delivered into a room of the piping system, to which a buffering pressure vessel can be connected and from where the gas, after a previous cooling to approx. T k, flows through the valve 4 acting as an inlet valve into the working volume, which the refrigerating machine can be assigned.

- the entire moving structure of 55-60 is enclosed so tightly in the operating state by a housing 61 that as little dead space as possible remains, since within this housing, which is connected to the working volume, the pressure is changed periodically, i.e. this housing is part of the pressure vessel. Since the flow area of the heat exchanger when using car coolers and the space required for the frame supporting it is significantly smaller than the area in the working volume perpendicular to the stroke, the movement sequence shown in Fig. 9 T was chosen, with no regenerator at the time period abc Heat exchanger structure 43 is present and, above all, the gas flows through the car cooler.
- the regenerators 40 and 41 lie close to the heat exchanger structure, the large-volume interstices of which are filled with wood (or GRP) so that the flow through the regenerators is as uniform as possible.

- the thermal expansion of the material becomes a problem with the desired size (100 liters working volume) of the machine This is countered by the fact that the pressure vessel 47 itself largely remains at ambient temperature and is insulated from the hot interior (for example with glass foam 107) to fill the space
- the cylinder wall 44 in the stroke direction is then formed from two layers of staggered sheet metal strips with a width of 20-30 cm, the approx. 3-5 mm wide joints running in the stroke direction.
- the surfaces of the pressure housing arranged largely perpendicular to the stroke direction are also e.g. largely insulated with glass foam 107 to fill the interior, which is held by a reinforced flat sheet.
- this sheet must be generously cut out in the direction of its center of area and have a corresponding distance from the border at the edge.
- Valves 48 and / or 49 are opened or kept open via a Bowden cable or linkage by a lever which is pressed with a roller onto control plates which are attached to the chain links of chains 70 or 81.

- the compressed gas emits thermal energy to the cooler.
- the gas in the working volume has reached the highest average temperature T m (t).
- the outlet valve is closed again by the pressure in the working volume which is lower than that of Pi.
- the pressure in the working volume is still too great for the inlet valves to open, so that the reduction in T m (t) leads to a reduction in the pressure P (t) in the working volume.

- This partial cycle process drives a second partial cycle process, which pumps from the partial volume of the working volume, which is only delimited by regenerator 41, into the partial volume, which is only delimited from the working volume by regenerator 36
- a valve that is controlled by the temperature of the endangered partial volume can prevent this process from being started unintentionally by a sticking valve and can lead to destruction due to overheating, which valve causes a constant pressure in the working volume in an emergency. If the outlet valve is opened by a correspondingly lower selection of the pressure Pi already a small fraction of the time period abc after the point in time a at which the lowest average gas temperature prevails in the working volume, the pressure in the working volume is increased in this cycle process, if the partial volume delimited only by regenerator 41 and the part volume adjacent to the cooler largely the maximum and that delimited only by regenerator 36

- the pressure PI can be set so that an analog one for the corresponding partial volumes
- the partial volumes of the working volume between two of the regenerators 36-40 are reduced by the fact that the gas flowing through is further expanded in the time period efg between two regenerators. These partial volumes are supplied with thermal energy during a period by virtue of the fact that due to the gas quantity of the mass m A which is hotly taken up into the working volume by the inlet valve 48 and which is released cooler through the outlet valves 49, the regenerators 36-39 flow through the hottest side with one around them Gas quantity of mass m A larger gas volume is flowed through than from the cooler side.

- the flow resistance of the regenerator acts.
- P x can be selected so that the total amount of gas drawn in remains constant, ie this measure reduces the
- T l5 P 1; P 0 is the same amount of heat energy supplied to the regenerators 36 to 39 only during a period when the exchanged amount of gas is cooled more.
- a larger temperature difference Ti - T 2 can be achieved with the same pressure ratio Pi / Po.
- the temperature T 2 can be stabilized relatively easily by a simple thermostat control for the valve 49 corresponding to the inlet valve 35 in FIG.
- the inlet valve 35 is only opened when the gas (15) exceeds the specified temperature (even).

- the pressure of the gas in the working volume is increased to the maximum value due to the rise in the average temperature of the gas when the valves are closed by the displacement of the regenerators 36-41. Due to the adiabatic compression of the gas flowing through the partial volumes between two of the regenerators 36 to 39, thermal energy is supplied to these regenerators.

- the water level in the pressure vessel can be changed periodically (by actuating a compression device) and an (additional) pressure change can be achieved in this way.
- regenerators 36 to 40 For the flow through the regenerators 36 to 40 can also be achieved in that a sheet metal is sealingly attached to the edge of each of these regenerators, which is always immersed in the water even in the periodic operating state. In order to minimize the losses due to the heat transfer surface, this sheet must be provided with a water-repellent surface with a low thermal conductivity.

- Valves must be used to regulate the amount of gas flowing into the working volume in order to maintain a certain temperature difference during cooling or heating of the periodically exchanged amounts of gas. If the cooler gas is to experience only a minor change in temperature, gas is sucked out of the working volume as described above during its inflow process through a valve 49 acting like valve 35 with a fan. Since the gas from two different partial volumes, which are separated from one another by a regenerator 40, can flow out of the working volume through different valves 49 and 213 into different spaces of the piping system, (together with a valve which acts like valve 35), the two

T, flows through the valve 49 acting as an inlet valve into the working volume, which can be assigned to the refrigerator.

- the corresponding connecting rods of the chain drive described in FIG. 8 can act directly on the corresponding tubes of the tube bundle 109.
- regenerator to be flown through must be arranged inside the displacer and the flow resistance in the gap between the cylinder wall and displacer must be of the same order of magnitude as for the regenerator at a comparable flow rate. This may require an additional seal.
- the heat transfer surface for cooling through the cylinder wall 1 15 is increased by slots in the stroke direction, the working fluid flows around the displacer in this area and must also flow through a regenerator in this displacer.

- FIG. 22 looks very different.
- the working volume is largely delimited by a pressure housing 128, inlet and outlet valves 130 and 129a, b.Tn this working volume is caused by the regenerators 131-136 which are stationary relative to the pressure housing and which are connected to the regenerators 131 -135 connected partition walls 137-141, walls of the pressure housing and displacer sealed on these walls, displacer 142-146 partial volumes delimited
- the periodic size change of these partial volumes corresponds to the periodically changed stroke difference of the corresponding regenerators in FIG. 9T.
- the Displacers 142-145 are moved periodically simultaneously
- the racks 146-149 attached to these displacers are driven by gearwheels on a shaft 150a
- This shaft is sealed out of the working volume by the pressure housing and on it the ends of a chain 150 are wound up or unwound, which is stretched over two chain wheels 151 and on which the connecting rod 152 of such a chain transmission construction acts, which in FIG. 8 attacks the regenerator 36 Drives
- this chain transmission through the shaft 154 driven by an electric motor, another similar chain transmission 155, which moves the displacer 146 in the same way, is connected in such a way that there is a phase shift of approximately a quarter period with the movement of the other displacers
- each of the displacers 142-145 in FIG. 22 adjoin one of the partial volumes between two of the regenerators 131-135 and the partial volume adjacent to the cooler 156
- the displacer 142-145 can practically no longer be flowed around, otherwise the desired balance will not be formed
- valve 129a can be used like valve 35 in FIG. 1
- FIG. 22 the construction of FIG. 22 can also be designed or used as an engine, chiller, heat pump Liquid displacement piston
- the displacement pistons are designed as a vibrating liquid column with a float in a U-shaped container
- the movement of the liquid displacer piston is controlled and driven by a belt 159 which is tensioned on a shaft 158 and which is attached to the float 157
- liquid displacer pistons perform largely the same deriodic movements as explained for FIG. 22 with FIG. 9, several of the liquid displacer pistons corresponding to the displacer pistons 142-145 can also be driven from a shaft 158 corresponding to 150a with this construction in the operating state
- This shaft 158 can be controlled and / or driven as described for FIG. 22
- valve 160 Before liquid can get past a float 157 into a hot room, which could lead to a dangerous explosion of steam, the valve 160 should be closed by the extreme position of the float 157 and the flow rate
- this valve 160 remains closed during the time periods abc with the extreme position of the corresponding float by means of a temporary locking.
- the displacer 157 is also temporarily locked when it hits the seal which is firmly connected to the pressure housing 161 is printed
- the surfaces of the heat exchanger 162 are heated or cooled by immersion in the oscillating liquid.
- valve 166 acts as a nozzle. This drives the pendulum movement of the liquid column
- the working volume for the working fluid which goes through the cyclic process is reduced to increase the compression together with that the total volume of the working volume and the volume of the oscillating liquid by displacing the slidingly sealed piston 167 and increased again in the time period efg
- the mechanical energy exchanged can at least partially be temporarily stored in the oscillating liquid column, which connects to the piston 167 min two heat exchangers in a pressure housing according to the invention:
- each of the regenerators 131-134 in FIG. 22 must be provided with a heat exchanger on the same side with regard to the flow as in regenerator 135.
- the liquid can then flow through these heat exchangers one after the other and thereby exchange thermal energy at several temperature levels (see FIG. 3).
- the amount of working fluid in the non-overlapping partial volumes of the working volume divided by the regenerators with heat exchangers then largely have the temperature of the heat exchanger . If the working fluid flows into a working volume of an engine according to FIG. 8 in the operating state, it mixes with cooler working fluid. The heat energy given off compensates for the irreversibility through heat conduction, shuttle losses or limited quality of the regenerators.
- a design based on FIG. 23 or FIG. 21 is also associated with less design effort. since here too the heat exchangers do not have to be moved and the connections for the liquid exchange of the heat exchanger are not a problem.
- the inlet and outlet valves are arranged as shown in FIG. 22.
- the gas escapes from the partial volume of the working volume at the highest temperature and the partial volume adjoins the heat exchanger at the corresponding temperature. If the temperature change of the gas during the adiabatic expansion in the external turbine is significantly smaller than the temperature change of the liquid, the gas is released into and out of a (the hottest) partial volume of the working volume by valves.
- the thermal energy given off by the exhaust gas of a gasoline or diesel engine during cooling can be used to generate additional mechanical or electrical energy or to charge the engine with filtered fresh air at higher pressure and therefore not have to use any mechanical energy for a turbocharger or compressor. whereby, compared to an engine without this supercharging, a better output volume and in any case a better efficiency can be achieved.
- the thermal energy emitted by the exhaust gas of a gas turbine during cooling can be used to supply the cool gas with filtered, cool fresh air at higher pressure.
- the compressor of the gas turbine used here can be designed so that it with unchanged pressure in the combustion chamber and with unchanged
- Gas flow rate requires less drive energy, which leads directly to a greater useful output with the same fuel consumption and better efficiency.
- the efficiency in this case is greater due to a synergy effect than the sum of the efficiency of the original gas turbine and the efficiency of the thermal compressor (gas compressor), since the power applied by the thermal compressor for gas partial compression from the original compressor of the gas turbine only with less favorable Efficiency can be achieved, driven by the branching of mechanical shaft power. Possibly. it is also possible to use a conventional gas turbine. A relative pressure increase in the gas turbine can then be expected, which decreases continuously from the fresh air inlet to the exhaust gas outlet, as a result of which the power density and efficiency are increased.

- a valve 312 is attached to the connection from the working space to the tube with the vibrating liquid column, which has a stop in the direction of flow towards the working space, against which the ⁇ valve plate 313 is pressed in a sealed manner as soon as the liquid column has moved too far in the direction of the working space.
- Another ⁇ L bertikvent ⁇ l 315 coupled to the same space 308 leads instead to the pressure vessel 309 to an external container 316.

- Mirrored film or a thin glass mirror must be applied to plywood.
- mirror trough elements 317 are arranged so that especially in
- Elements 317 reflected solar radiation can be absorbed on the smallest possible area 321.
- This structure of the concentrating mirror can be easily integrated on a house roof in terms of construction and architecture:
- optical concentration factor is also good enough, if only the absorber
- the edges of the mirror segments 323 emphasize the vertical so that the mirror is more emotionally accepted as a roof.
- a channel 324 is arranged between two mirror elements, in which water can run off.
- the mirror system thus forms the top roof skin.
- the snow-covered structure also has an advantageous effect here, since no horizontally running channels are formed in which water or wet snow can accumulate, causing water to penetrate. Frost damage and leakage can result in the mirror structure being moved around an axis as an alternative. ww yy i m PCT / DE98 / 02827
- the absorber 322 is sensed and rotated so that its main or symmetry axis 325 corresponds to the main radiation 326 of the absorbed radiation.
- the absorber 322 is always located in the plane of symmetry of the parabolic nominal mirror 317, as a result of which a good concentration ratio is achieved.
- the absorber is arranged at a greater distance in the order of the extent of the TWD from the TWD, with the side walls being mirrored, so that a more uniform radiation density occurs at the absorber.
- the insulated container 328 with a reflecting inner wall forms the rear wall of an upstream solar collector 331. It supplies the heat transfer medium with energy before it can flow through the TWD 327.
- This collector 331 is supplied with solar radiation energy by a further mirror 332 connected to the absorber 322, which the TWD 327 just missed. Also in this collector 331, the absorber 333 is flowed through by the warm medium ⁇ e__ ⁇ er medium, which the ⁇ g— ' entire absorber structure from
- Piping system 334 is supplied via at least one movable connection.
- the absorber structures 322 of a plurality of mirrors aligned in parallel with identical focal lengths are connected relatively directly to a pipeline system 334 which is also moved.
- a ⁇ bsorber is movably connected via three racks with three fixed points and the distance can be changed with motor power controlled by a shift in the rod direction.
- At least one absorber 322 is slidably connected to a toothed rack in a controlled manner with motor force, which is movably connected via two further toothed racks with two fixed points each and the distance can be changed in controlled manner with motor force.
- At least one absorber is movably connected to another absorber and is only moved with two racks.
- the connecting pipe 334 of the heat transfer medium also fixes the absorber 322 attached to it with respect to the pipe axis.
- the rotation of an absorber about an axis of rotation perpendicular to the horizontal east-west axis and to the axis of symmetry of the absorber in the main beam direction takes place through the parallel coupling by ropes with a rack, which at 12 noon as close as possible to a vertical plane in the north-south direction
- the pivot points 336 of the ropes are arranged on one plane through the axis of rotation 337 of the absorber 322 or the axis of rotation of the attachment of the toothed rack to the absorber structure and lie on both sides of these axes of rotation 337, ...
- an absorber 322 is rotated about an axis of rotation perpendicular to the horizontal east-west axis and to the axis of symmetry of the absorber in the main beam direction by the parallel coupling by rods with a rack, which at 12 noon as close as possible to one vertical plane runs in the north-south direction, the fulcrums of the rods being arranged on a plane through the axis of rotation of the absorber or the axis of rotation of the attachment of the rack to the absorber structure and, when projected into a plane perpendicular to the axis of rotation of the absorber, at least approximately form a parallelogram with a line through the axes of rotation, the ideal angle of which is 90 °
- the rack is formed by a carrier on which a chain is fastened, in which a sprocket engages, which is driven by a motor via a self-locking gear.
- the sprocket is guided on the chain by at least one roller that is pressed against the carrier from the other side.
- a rack can be placed vertically and extended to near the ground so that the A. absorber structure along this rack can be lowered to near the ground by moving the engaging drive.
- the fulcrum for the absorber structure with gas guide channels 322 is further away from the large main mirror 319 in the beam direction than the fulcrum for the smaller mirror 332 additionally arranged around it
- the translucent thermal insulation 327 consists of a flat support structure arranged in the radiation direction, e.g. from several slotted sheets with slots arranged perpendicular to the radiation direction, which is surrounded by a transparent and / or especially reflecting structure made of glass fibers in radiation direction, optionally in addition or as a replacement for the glass fibers, glass tubes or rods are arranged in the beam direction.
- the collector 16 is completely covered by glass 23
- the TWD 327 is only covered by glass 337 as far as is necessary to guide the heat transport medium air in a flow that is sufficiently parallel to the TWD 327.
- the currents in the air are controlled in particular when the solar radiation is weakened so that more air is blown out of the collector 331 in front of the TWD 327 than through the TWD 327 is suctioned off.
- the pollution of the TWD by unfiltered outside air is reduced.
- the solar radiation energy is concentrated by the mirror structure primarily on the translucent thermal insulation TWD 327 of the absorber.
- the solar radiation will penetrate at least the front part of the TWD 327 predominantly without absorption and will then be absorbed in the absorber structure.
- the heat energy can only escape from the absorption area after the decisive obstacles have been overcome by the TWD 327, since the thermal radiation from the absorber or each emitting surface is only largely absorbed by surfaces which have a relatively small temperature difference and which also suppresses convection due to the large areas of the TWD 327 that subdivide the relevant convection space.
- the flow of the heat transfer medium (eg air flow) is absorbed there in jet direction.
- the absorber is divided into areas, the flow of which is controlled in a temperature-dependent manner in order to avoid mixing of the heat transfer medium with large temperature differences in the outlet manifold 330.
- the flowable cross section should remain constant in this area. This is achieved by bimetals 339 regulating the flow, two of which are each connected to a bar 340 like a scale, the suspension of two corresponding bars being movably connected to a centrally suspended bar
- the pipeline 330 through which the hot gas is removed from the absorber 322 is encased with an insulation 341 with an outer surface 342 with good heat conduction and optionally good or selective absorption, which in turn is largely completely encased by translucent thermal insulation 343 and in one Room 344 ⁇ runs through, which is flowed through by the warm gas of the heat energy cycle on the way to at least one absorber 322 and which for the fall autumn 12:00 noon on the directly illuminated side by an impermeable translucent insulation 345 and on the other side by one
- Weather protection adjoins and which reflects the incident light, in particular, onto the side of the inner tube 342 which is not directly illuminated, is surrounded and is thus completely encased.
- a bulk material storage works thermodynamically well and is constructed with a tolerable effort by dividing the bulk material 348 through which the heat transfer medium (e.g. air) flows through at least one insulating, non-flowable intermediate layer 349 into concentric shells with a zvlinderformie jacket with a vertical axis and outwardly curved floor and top surfaces the flowable transitions 350 from an inner shell filled with debris to the adjacent outer shell occur through openings in the insulating cylinder jacket 349, which are arranged on both sides in the area of a plane through the cylinder axis and thus guide the flow through non-flowable connections running in the area of this plane is that the shells can only be flowed through in one direction of rotation about the vertical cylinder axis.
- the heat transfer medium e.g. air
- a transition between two half-shells filled with debris is only possible if there is flow through a vertical shaft 351, via which the warrant carrier can also be exchanged.
- the flow can be controlled in places by reducing the size of the inflow channel in such a way that only heat transfer medium flows in a narrow temperature range in the shaft.
- One of the outermost insulation layers 352 is flowed through from one fill layer to the other. This results in a decisive curvature of the temperature professional, which means that due to the smaller slope on the cooler side, there is only a lower loss of heat energy flow than without the flow against the temperature gradient.
- the flow paths are extended by additional, smaller, non-flowable barriers 355.
- the flow through these bulk material layers 353 is relatively even, the flow paths are approximately the same length as in the cylinder jacket 356 and there is no unfavorable mixing of heat transfer medium at different temperatures.
- the bulk material storage is heated to well over 100 ° C when the hot and cold air flows in and the bulk material storage is removed a few weeks later by air that flows into the outer storage area at approx. 50 ° C and through one of the Air ducts are removed at 120 ° C - 150 ° C and then cooled by a heat exchanger that heats water from approx. 40 ° C to 100 ° C, which is taken from an insulated water tank in the lower area and fed into the upper area.
- the waste heat from the ⁇ X arm power engine operated as a hot gas engine is used at Novam to supply energy for heating and hot water.
- a hot gas engine operated as a hot gas engine
- a high synergy effect is achieved if the storage tank is not filled with pure water, but with biomull and fakahen.
