Definitions
- the invention relates to a storage probe, also known as geothermal probe, which is provided for exchanging heat between a heat transfer fluid and the soil surrounding the storage probe, in which the storage probe is arranged in the operating state.
- the invention relates to a large-volume coaxial storage probe, with a discharge pipe arranged in an inflow pipe.
- Memory probes can be coaxial or U-shaped.
- U-shaped memory probes have an inflow pipe which leads down into the ground and is connected at a lower end in a connection region in a fluid-conducting manner to an outflow pipe.
- the heat transfer fluid also called heat transfer fluid
- the inflow tube is a probe outer tube and the outflow tube is a probe inner tube located within the probe outer tube. Outside the probe inner tube and inside the probe outer tube, an annular space, also called a heat transfer space, forming a heat transfer area is provided.
- the arrangement of the probe outer tube to the probe inner tube is coaxial.
- the connection region is formed in the case of a coaxial storage probe through an opening of the probe inner tube, so that the heat transfer fluid located in the probe outer tube or in the annular space can flow here into the probe inner tube.
- the heat transfer fluid is introduced at an inlet into the storage probe.
- pressurized heat transfer fluid is typically forced to pass the entire length of a storage probe twice, once down the inflow tube and once in the inflow direction Inlet direction up the exhaust pipe.
- the amount of heat transfer fluid passed through the storage probe per time is referred to as the volume flow.
- the heat transfer fluid is discharged upwards again through the probe inner tube / outflow tube and can be removed at a drain.
- the probe inner tube may also be connected to the inlet and the probe outer tube also to the drain.
- the temperature difference between the heat transfer fluid flowing into and out of the storage probe is referred to below as the temperature gradient.
- the soil as a heat reservoir is a heat flow or heat output, short heat taken.
- the temperature gradient between the heat transfer fluid introduced and the heat transfer fluid removed is typically a few degrees. Typical values are between -2 ° C and 1 ° C and conductance values between 2 ° C and 5 ° C.
- the temperature gradient is relatively low and the temperature of the exiting from the memory probes heat transfer fluid does not yet meet a heat demand as it is required, for example, for heating of living spaces.
- the heat output can be made available by means of a heat pump, wherein the efficiency of a heat pump indicates how effectively a supplied by the heat transfer fluid heat output is converted into a heat request for heating.
- a supplied heat output at a low temperature level is used to evaporate a heat medium, which is located in a second fluid circuit, in an evaporator.
- the evaporator is in this case Component in which the heat obtained from the storage probes is supplied to the heat pump at a low temperature level.
- the heat transfer fluid derived from the storage probes flows through the heat exchanger and transfers its heat to the second fluid circuit.
- the heating means is fed to a pump which compresses the now gaseous heating means and thus brings it to a higher pressure level. This heats the gaseous heat and just this heat can be used to heat a living room. In the delivery of its heat to the living room cools and condenses the heat.
- the heat transfer fluid in the storage probes may be eliminated if the heating medium itself circulates through the storage probes.
- the invention is not limited to memory probe heat circuits with two separate circuits. Usually, a plurality of storage probes are used in a storage probe heat circuit, since the usable temperature difference of a storage probe is usually not sufficient to evaporate the heat medium in the second fluid circuit.
- the temperature of the soil is constantly about 10 ° C over the year, and increases by about 1 ° C per further 30 meters.
- the achievable discharge value is often insufficient because the heat exchange is not effective enough.
- the heat transfer fluid can keep a once reached temperature lossless as long as possible, especially when multiple memory probes are connected in series.
- especially large-volume storage probes offer. With a larger meter volume, a larger amount of heat is needed to reach a higher temperature. However, once it has reached a temperature it offers the advantage of a longer temperature stability for the same reason.
- Large-volume storage probes are characterized by the fact that an inner diameter of the inflow pipe delimited by an inflow pipe inner surface and an outer diameter of the outflow pipe delimited by the outflow pipe surface are such that a meter volume> 10 l results in the annulus and the heat transfer fluid, without further intervention within the annular space in the Essentially laminar flows. Whether a flow is laminar depends on the geometry of the flow path, the viscosity of the heat transfer fluid, and the flow rate. This results in the so-called Reynolds number, which is a measure of when turbulence occurs in a flow. In general, the higher the flow velocity, the sooner the critical Reynolds number is exceeded. A low flow rate ensures a (nearly) laminar flow.
- the heat transfer fluid has more time to absorb the heat at the inlet tube inner surface.
- a laminar flow can be regarded as disadvantageous, since unequal tempered layers form within an (approximately) laminar flow.
- the non-tempered layers are vertical and thus parallel to the Einströmrohrinnen design, wherein in the vicinity of the Einströmrohrinnensynthesis warmer layers are present, which act as insulators of the inner layers.
- the object of the invention is to improve the heat exchange between the heat transfer fluid and the heat reservoir in storage probes, and thus the efficiency of Speichersondenzieklä13n.
- the object of the invention enables the effective use of memory probes in regions where laws limit the allowable drilling depth.
- a storage probe according to the invention is surrounded by soil in the operating state and serves to exchange heat between the soil and a heat transfer fluid located within the storage probe.
- the storage probe comprises an inflow pipe through which the heat transfer fluid is introduced into the storage probe, and thus into the soil, and an exhaust pipe, through which the heat transfer fluid is discharged again.
- the heat transfer fluid is introduced via an inlet into the inflow pipe and the direction from the inlet in the direction of the earth's interior is referred to as inflow direction (flow direction).
- the outflow pipe is arranged within the inflow pipe, so that an annular space, into which the heat transfer fluid flows, is formed between an inflow pipe inner surface and an outflow pipe outside surface.
- the heat exchange takes place in a storage probe according to the invention in the inflow pipe.
- the invention relates to large-volume storage probes, in which the diameter defined by the inflow pipe inner surface is so large that, as a rule, a laminar flow prevails.
- the defined by the Auströmrohrau touch inside diameter of the discharge pipe is chosen so that there is usually a meter volume of more than 8 I in the annulus.
- the diameter defined by the inlet tube inner surface is greater than 120 mm and the meter volume of the annular space is greater than 12 l. It has been found that it is precisely a repetitive alternation of near laminar flow and mixing of the heat transfer fluid that causes effective heat exchange.
- the heat transfer fluid flows laminar into the inflow pipe.
- the storage probe further comprises at least two mixing bodies spaced along a longitudinal axis of the discharge pipe within the annulus.
- the distance between the mixing bodies is chosen so that the heat transfer fluid, after it has passed a mixing body calmed down again and again sets laminar flow before it hits the next mixing body.
- the distance between the mixing bodies 1 to 2.5 m, preferably between 1.5 m and 2 m, it should be noted that these values are to be regarded as an order of magnitude and to determine the ideal distances, the flow rate, the inner diameter of the inflow pipe, the outer diameter of the exhaust pipe and the viscosity of the heat transfer fluid must be taken into account.
- a mixing body has at least two partial annular discs with an outer edge, an inner edge and two free ends each, which delimit a partial annular surface.
- the partial annular discs can be connected in any way with the exhaust pipe, for example, welded or glued.
- the components of the mixing body can be made of the same material, preferably of thermoplastic material, such as the outflow tube, which ensures easy connection of the partial annular discs to the outflow tube.
- the inner edge abuts against the discharge pipe outside surface.
- the mixing bodies can be arranged variably in the annular space in order to be able to coordinate the distances between the mixing bodies to the respective specific task of the storage probe.
- the mixing body can comprise a sleeve, via which the partial ring disks are arranged on the outflow pipe outside surface.
- the sleeve For locking the sleeve then serve, for example, holes with internal thread, which are formed along the longitudinal axis of the discharge pipe in the Ausströmrohrau L.
- a grub screw can then be used to fix the mixing body.
- the outer edge of a partial ring disc is spaced from the inlet tube inner surface and forms with this an annular gap through which a part of the heat transfer fluid can flow.
- this annular gap is 1-12 mm, in particular 4-8 mm.
- Each one of the free ends of a partial annular discs is arranged spaced from one of the free ends of an adjacent partial annular disc.
- adjacent partial annular discs are arranged differently obliquely to an orthogonal plane of the longitudinal axis of the exhaust pipe.
- Substantially spaced means that an opening is formed between each one of the free ends of two adjacent partial ring disks, through which a flow path with a vertical component leads along the longitudinal axis of the exhaust pipe.
- a portion of the flow path of different sizes leads, with a vertical component, directly along the discharge pipe outer surface.
- the partial annular surfaces are configured as half-annular surfaces, so that in each case the free ends of a partial annular disc enclose an angle of 180 ° with one another. Conceivable, however, are other variants of a circle segment section. If the angle enclosed by the free ends of a partial ring disk is less than 180 °, the proportion of the flow path increases with a vertical component that leads directly along the discharge pipe outer surface.
- the oblique part annular discs cause a further flow path with a rotational component over the partial annular surfaces and around the exhaust pipe around.
- flows the heat transfer fluid depending on the arrangement of Operaringusionn clockwise or counterclockwise around the exhaust pipe.
- the partial ring disks of the various mixing bodies are each arranged such that the direction of the rotational component of the flow of adjacent mixing bodies differs.
- the mixing is produced precisely in the region of the inlet tube inner surface and in the region of the discharge tube outer surface, that is to say precisely in the regions which in the laminar flow represent the layers with the greatest temperature difference.
- the inner layers hardly absorb any heat. Therefore, mixing of the heat transfer fluid eliminates this stratification.
- the boundary layer between the flows is broken up. This rupture and the resulting mixing results in an overall effective heat exchange between the soil and the heat transfer fluid.
- the special arrangement of the mixing body the necessary length of a memory probe, which is required so that the memory probe reaches a sufficiently large temperature gradient or conductivity, can be reduced.
- the storage probe can thus also be used in regions in which the drilling depth is geologically or legally limited. Efficient heat exchange is achieved by switching between near laminar flow and mixing of the heat transfer fluid reached.
- the storage probes according to the invention are also suitable for cooling due to their efficient heat exchange with the soil.
- a circulation pump at relatively short intervals, even promotes the heat transfer fluid in a connection heat circuit with at least one storage probes or set in motion when no request for heat from a subsequent heat pump in a customer cycle.
- the circulating pump operates according to the invention independently. This ensures that even at standstill of the consumer heat circulation, a circulation and thus a mixing of the heat transfer fluid within the storage probe. This in turn leads to increased heating of the heat transfer fluid, which significantly increases the efficiency of the heat pump. In principle, therefore, even if it is not needed, the heat transfer fluid is already preheated inside the storage probe before it reaches the heat pump. In particular, this also reduces the time it takes for the heat pump to provide a heat request.
- FIG. 2 shows a cross section through an inflow pipe in a region in which a mixing body is arranged
- Fig. 1 shows schematically a portion of an exhaust pipe 18 to which a mixing body 20 is arranged.
- this consists of five partial annular discs 22, each with a partial annular surface 21, which is bounded by an outer edge 25, an inner edge 23 and two free ends 26.
- the partial annular discs 22 are arranged at different obliquely to an orthogonal plane of a longitudinal axis x-x of the exhaust pipe 18, wherein each one of the free ends 26 spaced from one of the free ends 26 of the adjacent partial annular disk 22 is arranged.
- the two free ends 26 of adjacent partial ring disks 22 form an opening 24 which extends in a vertical direction along the longitudinal axis x-x of the exhaust pipe 18.
- the free ends 26 of adjacent partial annular discs 22 are arranged substantially at a distance from one another and touch each other only in the area of their outer edge 25.
- the oblique arrangement of the partial annular discs 22 resembles the appearance of the mixing body 20 of a helix extending in a plan view in the direction of the longitudinal axis xx, clockwise to the exhaust pipe 18 winds.
- FIG. 2 shows a simplified cross-section through an inflow pipe 12 of a storage probe 10 according to the invention in a region in which a mixing body 20 in the annular space 15 between an inlet pipe inner surface 16 and a Ausströmrohrauz Chemistry 19 is arranged.
- the mixing body 20 shown in FIG. 2 corresponds to the mixing body 20 known from FIG. 1 in a schematic representation.
- an annular gap 28 is formed between the outer edges 25 of the partial ring disks 22 and the inlet pipe inner surface 16.
- the heat transfer fluid substantially flows along three different flow paths.
- the heat transfer fluid flows (approximately) laminar in the annulus 15 toward the mixing body 20.
- the direction of the laminar flowing heat transfer fluid is represented by large open arrows.
- the direction of the arrows corresponds to the inflow direction of the heat transfer fluid. If the laminar-flowing heat transfer fluid meets the partial ring surface 21 of the first partial ring disk 22 in the inflow direction, it is guided in a rotational movement clockwise around the outlet pipe 18 via the further partial ring surfaces 21.
- This first flow path is shown as a dashed spiral with arrows around the exhaust pipe 18.
- FIG. 1 By already in Fig. 1 shown openings 24 between two part discs 22 results in a second flow path with a vertical component, with a part directly along the Ausströmrohrau present Structure 19 leads.
- This second flow path is represented by a small open arrow in the opening 24.
- the representation of the small open arrow has been omitted in one of the openings 24a, instead a small turbulence 29 is shown, which illustrates the mixing of the heat transfer fluid at this point.
- the annular gap 28 between the outer edges 25 of the pitch discs 22 and the Einströmrohrinnen Chemistry 16 represents a third flow path. This is indicated by narrow long arrows. Also in this area, the mixing of the heat transfer fluid by small turbulence 29 is partially shown.
- the heat transfer fluid flows into the outflow pipe 18.
- the flow direction within the outflow pipe 18 is represented by a black arrow. He is opposite to the direction of inflow directed.
- FIG. 3 likewise shows a cross section through an inflow pipe 12.
- three mixing bodies 20 I, 20 II, 20 III are arranged within the annular space 15.
- the representation of the mixing body 20 I-III in the annulus 15 corresponds to that of FIG. 2 known representation. It should be clarified that the distance between the individual mixing bodies 20 I, 20 II, 20 III is selected such that always a substantially laminar flowing heat transfer fluid, indicated by large open arrows, on the partial annular surface 21 of the first partial annular disc 22 of the respective mixing body 20 I, 20 II, 20 III meets.
