    The invention relates to a heat accumulator with a different Heizwassertemperaturen Heizwasserspeicher having a circulating connected to the Heizwasserspeicher and a free convection of Heizwassers flow channel and at least one provided in the flow channel at least partially helical line for guiding a standing in heat exchange with the heating water liquid.
    In order to heat service water by means of a free convection of heating water of a heat storage, it is known from the prior art (WOOO / 29789 A1) to provide a flow channel in Heizwasserspeicher, are introduced into the pipes for service water. Although such Thermosiphonsysteme are inexpensive, reliable and low maintenance, but have relatively low Konvektionsströmungen in Strömungskanai and thus low efficiency in the heat exchange between heating and service water. Therefore, such heat storage are not suitable for high volume and temperature requirements in the production of process water.
    In addition, in a heat storage known (DE19848648C1), a water heater a Strömungskana! for heating water to heat it by means of a free convection. This convection is generated by the heating water cooled by a hot water extraction, precipitates out of the flow channel and so hot heating water trailing into the flow channel. Although a hot water tank can cover a predetermined consumption via its storage volume, its flow around the heat exchange with the heating water can not be particularly effective. Relatively large service water supply 18/02 2011 FR 18:20 [SE / ΈΜ NR 8967] @ 004 18/02 2011 18:23 FAX 0761263884 PA JELL @ 005/018 -2 -
    Memory are therefore required to meet quantity and temperature requirements, because after a depletion of the heat of the hot water tank is expected only with a slow reheating. This can not be remedied by a poor heat-conducting side wall of the flow channel for channeling the heating water, especially since the flow channel is designed in the manner of a heat trap.
    The invention is therefore based on the object to improve a heat accumulator of the type described in such a way that despite a Thermosiphonsys-tems for heat exchange between heating water and liquid or a service water, a high efficiency for adequate coverage of the quantity and temperature requirements is possible. In addition, the dynamics of the Ther mosiphonsystems should be improved so as to quickly follow the changing volume and temperature requirements of the heat exchanger can.
    The invention achieves the stated object in that at least the wall of the flow channel at least partially has a thermal insulation.
    If the wall of the flow can has thermal insulation at least in some areas, then a comparatively small temperature difference in the heating water storage can create a basic convection in the flow channel compared to the state of the art. This basic convection can be maintained even if the lines in the flow channel have little or no heat exchange requirement with the heating water. However, in contrast to the prior art, this continuous, albeit possibly low, convection according to the invention opens up the possibility of ensuring comparatively high dynamics during discharge of the heat accumulator. It has been found that with varying power requirement to the heat exchanger, the free convection in their parameters can adapt relatively quickly, if it is assumed that a basic convection. Power peaks can therefore even be covered by such a heat exchanger so that comparatively high volume and temperature requirements can be met 006/018 • * * * * «« ··· «· * ψ 0 the. In addition, by the thermal insulation of the wall of the flow channel, an undesirable impairment of the convection flow can be reduced, which can allow comparatively high convection currents and thus a comparatively high efficiency at the heat exchanger. Such thermal insulation can be made possible, for example, if the wall clad with poor thermal conductivity materials or even the wall consists of such a material. Such thermal insulation with a comparatively high resistance to heat flow of thermal energy are known in the art, for example plastic foams. Advantageously, not only a free convection convection, but also in connection with the performance requirements of the heat exchanger free convection can be improved by the heat insulation according to the invention. This can contribute, for example, a course of the flow channel substantially in a vertical direction, so as to allow a low-resistance circulation of the heating water or to use the gravity of the heating water particularly advantageous. Preferably, the wall of the flow channel consist of a thermal insulation. Compared to the known from the prior art Thermosiphonsyste-men therefore not only structurally simple and thus cost a flow channel improved in terms of its free convection, but also the dynamics and performance of the heat exchanger flowing around it can be significantly increased.
    If the line is designed as a corrugated pipe, then the possibility opens up in a structurally simple way to further increase the efficiency of the heat exchanger. On the one hand, the waveform can provide for increased mixing and thus improved heat absorption from the tap water and, on the other hand, this waveform can also allow high flow velocities in the flow channel. Namely, this waveform can provide a reduced flow resistance in the flow passage even with a helical pipe, so that a disturbance of the basic convection can be kept small. In addition, owing to the Welian shape, a turbulent flow can be achieved in a structurally simple manner in the flow channel as well as in the line. 18/02 2011 FR 18:20 [SE / EM NR 8967] © 006 18/02 2011 18:23 FAX 0761263884 PA JELL 11007 / 018 • «« · • «
    -4- improved heat transfer or absorption are taken care of. In contrast to known thermosiphon systems, an improved dynamics can therefore be made possible even with a large heat exchange surface and thus a high efficiency of the heat exchanger.
    Simple construction conditions can result if the flow channel runs essentially along the jacket of the heating water store and if the line is designed as a service water line for heating process water. Advantageously, this also allows a considerable arc length of the helically extending line, whereby the surface for heating the service water and thus the efficiency of the heat exchanger can be significantly improved.
    In order to increase the flow capacity of the heat exchanger, it can be provided that a plurality of parallel connected hot water lines are provided in the flow channel. In addition, so that the dynamics of the heat exchanger can be improved because with the help of an increased cold entry in the flow channel, a rapid response of the convection is possible. Therefore, in contrast to the prior art, the heating water storage tank can be discharged comparatively quickly via the service water and nevertheless ensure a high bulk capacity via the service water pipes. In addition, can be made possible by an increased number of hot water pipes advantageously a low Graßigkeit the heat exchanger.
    Constructive simplicity may result if the service water pipes connect to a common manifold with a cold water connection and open into a common manifold with a hot water connection. In addition, it can be ensured uniform pressure conditions in the parallel lines for improved efficiency of the heat exchanger.
    In order to avoid a separate to the Heizwasserspeicher Windkessel, a pressure equalization tank can be provided in Heizwasserspeicher. In addition to a simple handling of the heat accumulator when connecting to a heating system, this pressure equalization tank can also be used for provide constructive simplicity to create a flow channel. For this purpose, the flow channel can connect to this pressure equalization tank and thus serve as part of the boundary of the flow channel when the pressure equalization tank at least partially delimits the flow channel. In addition, the surge tank can be used for winding the lines by this carries the lines of the flow channel. In addition to a constructive simplicity, therefore, a comparatively easy to handle heat storage can be provided. In a simple way, the pressure equalization tank on a gas as kompres-sible medium for pressure equalization.
    In particular, this flow channel can also lead the lines for heating the Heizwasserspeichers and be used, for example, to connect a Soiaranla-ge.
    In order to meet different performance requirements of the heat exchanger, the flow channel can have openings for heat exchange with heating water of Heizwasserspeichers over its channel length.
    If the pressure equalization tank has connecting openings in the flow channel, then the heating water taken up by the pressure equalization tank can be entered into the respective stratification of the heating water tank according to its temperature, if the pressure drops due to a discharge of the heating water tank. The Strömungskanai ensures namely for its related temperature allocation, so that the stratification in Heizwasserspeicher maintained and thus can be designed particularly stable.
    In the figures, for example, the subject invention is illustrated using an exemplary embodiment. 1 is a sectional view of a heat accumulator and Fig. 2 is a sectional view according to JI-IL of Fig. 1, 18/02 2011 FR 18:20 [SE / EM NR 8967] @ 008 18/02 2011 18:24 FAX 0761263884 PA JELL El 009/018 «· · · ·» * * * * • * * * * * * * * -6-
    3 is a partial elevational partial view of FIG. 1,
    4 and 5 are enlarged partial views of Fig. 1st
    The illustrated in Fig. 1, for example, heat storage 1 has a Heizwasserspeicher 2, which is surrounded by a storage wall 3. At this memory wall 3 includes a non-illustrated outer insulation. As is known, a heat-laden heating water storage tank 2 has a vertical temperature gradient, which causes different heating water temperatures 4, 4 ', 4 "of the heating water 5 in the heating water storage tank 2. These temperature-related density differences of the heating water 5 can be used to create a thermosiphon system. For this purpose, a flow channel 6 or 7 is provided in the Heizwasserspeicher 2, which is such circulation with the Heizwasserspeicher 2, that a free convection 8 of the heating water 5 enters this free convection 8 can be used, lines 9 and 10 in the flow channel 6 and 7 to apply heat, which lines 9 and 10 are used to guide a standing in heat exchange with the HeizwasserS liquid 11 and 12 respectively. This construction can now provide a heat exchanger 5 with circulating heat exchanger 13 or 14 without additional input of energy. The lines 9 and 10 are helically provided in the flow channel 6, 7 running to provide, inter alia, a high Wärmetauschfiäche, which can be seen for example in view of the lines 9 of FIG. 3 in connection with FIG. In particular, the efficiency and the dynamics of the heat exchanger 13 or 14 can be improved if the wall 15 or 17 of the flow channel 6 or 7 consists of a thermal insulation 16 and 18 respectively. On the one hand, a basic convection 8 'can thus be ensured and, on the other hand, a high requirement-specific convection 8 "(convection due to the respective performance requirements of the heat exchanger 13 or 15) can be generated because the flow duct 6 or 7 is thermally separated from the heating water reservoir 2 is what can be better taken from Figures 4 and 5. The free convection 8 according to the invention, consisting of basic convection 8 'and requirement-specific convection 8 ", is therefore particularly suitable for meeting high quantity and temperature requirements for liquid to be heated. Advantageous is the 18/02 2011 FR 18:20 [SE / EM NO 89671 0009 18/02 2011 18:24 FAX 0761263884 PA JELL © 010/018 -7-
    Flow channel 6 and 7 running substantially vertically in one direction, so as to be able to use the buoyancy or output flows or forces for heat exchange purposes unhindered, as can be seen in particular in FIG. In addition, even with low temperature differences in the Heizwasserspeicher 2 a basic convection 8 'can be ensured.
    The flow channel 6 extends along the jacket 3 'of the Heizwasserspeichers 2, whereby a particularly kink-free vertical flow channel 6 can form with relatively high stratification forces. In addition, the heat losses of the Heizwasserspeichers can always be introduced into the lower portion of Heizwasserspeichers 2 through the flow channel 6 along the jacket 3 '. The stratification of the Heizwasserspeichers 2 can thus remain relatively long, so that despite a cooling of Heizwasserspeichers 2 are still sufficiently high temperatures for heat exchange available. Stand-by losses can thus be reduced.
    In addition, this peripheral flow channel 6 also has relatively large dimensions, so that it is particularly suitable for lines 9 for heating service water 11, because here lines 9 can be laid with considerable length. An efficient heat exchanger 13 for heating service water 11 can thus be created.
    The line 9 is formed as a corrugated tube, as can be seen from the partial view of FIG. 3, which Welienrohrform can provide improved discharge of Heizwasserspeichers 2.
    In the flow channel 6 four parallel connected hot water lines 9, 9 ', 9 ", 9"' are provided so as to allow a more efficient discharge of Heizwasserspeichers 2. These lines 9, 9 ', 9 ", 9'" are also formed as a corrugated pipe to increase the energy content to be withdrawn from the Heizwasserspeichers 2 in addition. 18/02 2011 FR 18:20 [SE / EM NR 8967] ®010 18/02 2011 18:25 FAX 0761263884 PA JELL @ 011/018 -8-
    The service water pipes 9, 9 ', 9 ", 9'" are connected to a common manifold 19 with a cold water connection 20 and open into a common manifold 21 with a hot water connection 22. The manifolds 19 and 21 are provided in the heating water tank 2, which is a constructive Can create simplicity.
    The Heizwasserspeicher 2 also takes a pressure equalization tank 23 in the middle. The surge tank 23 is used to support the lines 10 of the second flow channel 7, which allows constructive simplicity of the heat accumulator 1.
    Different stratification in Heizwasserspeicher 2 can be met, if this flow channel 14 has over its channel length 14 'openings 24 for heat exchange with heating water 5 of Heizwasserspeichers 2. This opening 24 is S-shaped extending into the insulation 18 introduced to allow a special layering. Namely, the openings 24 may allow the heating water 5 of the flow channel 14 to fall back into the heating water storage 2 when its rise is limited by higher temperature layers.
    The pressure equalization tank 23 has a gas, in particular an inert gas 25, which can be filled via a gas pressure line 26 into the surge tank 23. In addition, this gas pressure line 26 can be used to vent the Heizwasserspeichers to befufilen this with heating water. After filling, the inert gas 25 can then be introduced in order to be able to absorb a thermal expansion of the heating water on the basis of the compressibility.
    The lines 10 in the flow channel 14 are connected, for example, with a soy collector, not shown, so that can be loaded via these lines 10 of Heizwasserspeicher 2. During this heating, a free convection 27 forms, which can connect with a free convection 28 from the pressure equalizing tank 23, in order to allow for a special loading of the heating water supply 18/02 2011 ER 18:20 [SE / EM NR 8967] @ 011 18/02 2011 18:25 FAX 0761263884 PA JELL® 012/018
    To be able to take care of it. For this purpose, the insulated outer wall 29 of the surge tank 23 has a connection opening 30. About this connection opening 30, the pressure equalization tank 23 can first absorb the thermal expansion of the heating water 5. If the heating water storage tank 2 is discharged, then advantageously the hot heating water 5 of the pressure compensation tank can be introduced via the respective opening 24 of the flow channel 14 into the associated stratification of the heating water storage tank 2. 18/02 2011 FR 18:20 [SE / EM NR 8967] ®012
