On the other hand, features that are included in the present description but are not visible or illustrated in the drawing will be readily understood by those skilled in the art.

1 shows a schematic view of a first exemplary embodiment of a storage housing composite of a heat / cold accumulator.

From the heat / cold storage 1, such as a thermal energy storage, a single storage enclosure composite 2 is shown partially open. As is clear from the illustration in FIG. 1, the storage housing composite 2 is constructed in layers of solid wood elements 3 and 4 made of solid wood. The two solid wood elements 3 and 4 are constructed without glue by means of solid wooden connector dowels, which are referred to as solid wood dowels 5 and can be seen in detail in Figs. 2 to 4. The overall structure of the storage enclosure 2 or the heat / cold storage 1, which contains at least two such Speichergehäuseverbunde 2, may be a block or alternatively serve simultaneously as an inner wall, outer wall, ceiling element or roof element for a building.

As illustrated in the illustration of Fig. 1, a meandering memory line 6 is quasi inserted in the front solid wood element 3 in the drawing by in the drawing in the direction of facing away side solid wood element 3 a channel-like receiving recess 7 storage line 6 according to Meander shape of the memory line 6 is included. The corresponding side of the solid wood element 3 is thus referred to as receiving side 8. Furthermore, it can clearly be seen from the illustration of FIG. 1 that the mounting surface 8 of the previously discussed first solid wood element 3 faces the adjacent upper solid wood element 4 and thus the corresponding second solid wood element 4 thus forms the receiving recess 7 covered with lying in memory line 6. With regard to the storage line 6, therefore, the first solid wood element 3 and the second solid wood element 4 are thermal insulations.

Furthermore, the illustration of Fig. 1 can be clearly seen that the two solid wood elements 3 and 4 consist of parallel juxtaposed solid wood boards 9 and 10 and the solid wood boards 9 and 10 of the adjacent solid wood elements 3 and 4 at an angle a , with 0 ° &lt; a &lt; 180 ° to each other, wherein in the first embodiment according to FIG. 1, the angle α = 90 °.

The storage line 6 has a supply end 11 and a discharge end 12, which extend from / to the outside of the storage housing composite 2 and is supplied or removed by the heat / refrigerant fluid. These supply ends 11 and / or the discharge ends 12 of each storage line 6 of each accumulator housing assembly 2 are connected via controllable valves 13 to a distribution system 14 or connectable.

The freedom from gluing the connection of the two solid wood elements 3 and 4 together is advantageous for the function of the heat / cold storage 1, as this is followed in a particularly advantageous manner, the thermal expansion of the solid wood of the two solid wood elements 3 and 4 of the heating of the heat / cold fluid , In particular, the structures of the heat / cold storage 1 are not unduly burdened or even damaged or destroyed.

Each storage case assembly 2 of the heat / cold storage 1 may contain more than two layers of solid wood elements, for example, a plurality of first solid wood elements 3 may be included, i. Such solid wood elements containing the channel-like receiving recess 7 with memory line 6 contained therein from the receiving side 8 ago and either follow each other directly or by one or more second solid wood element (s) 4 are separated or completed.

Preferably, at least every other layer of solid wood elements, channel-like structures / cavities, i. a channel-like receiving recess 7 is kept free or e.g. created by milling from the solid material. The storage conduit 6 in each receiving recess 7 consists of tubes or hoses of a suitable material, e.g. Alu-Plast, copper, stainless steel and the like and are preferably inserted and fixed so that the tube or hose ends lead out as supply ends 11 and discharge ends 12 from the storage housing assembly 2, which may for example form a block, and as connections to the distribution system 14th serve. The tubes or tubes of the storage line 6 are placed in the cavities, i. the receiving recess 7, preferably embedded with a natural material, e.g. dry clay, clay paste, sawdust, fine sand or the like. This material is advantageously the additional heat storage and better heat transfer from the pipe to the wood.

An essential aspect of the present invention is that the tubes or hoses of the storage line 6 of different Speichergehäuseverbunden 2, which may for example be arranged parallel to each other and thus in adjacent or superimposed planes are not directly coupled to each other, but separately controllable to the Distributor system 14 are connected or connectable, via appropriate controllable valves 13th

If necessary, water or a cooling liquid or generally a heat / cold fluid is pumped out of or into the distribution system 14 through the tubes or hoses of the storage line 6. Thus, heat may be carried into each storage case assembly 2, which may constitute, for example, a storage block, or generally the heat / cold storage 1, or heat may be taken out of the storage case assembly 2 or generally the heat / cold storage 1, as needed.

By temperature sensors in the heat / cold storage 1 and by an electronic control system, such as a computer control, can be accomplished that always optima storage enclosure 2 for storage or removal is driven by heat or cold. This can be z. B. via solenoid valves or thermally controlled valves with the principle of thermal expansion. Temperature sensors and controls (control electronics) are readily apparent to those skilled in the art in terms of function and arrangement and are therefore neither further described nor shown in the drawing.

The heat / cold storage 1 can serve to store heat and / or alternatively to store cold, i. The heat / cold storage 1 heat is removed by a cooled liquid is passed as a heat / cooling fluid, which lowers the temperature. The cooled heat / cold storage 1 then serves, for example, for the cooling of a building in hot climates or in warm seasons, whereby e.g. Also an excessive entry of solar heat in the summer can be compensated.

Heating and cooling can be made simultaneously in separate Speichergehäuseverbunden 2 the same heat / cold storage 1, since the Speichergehäuseverbunde 2 can be addressed separately by the controllable valves 13.

Any heat losses from the heat / cold storage 1 out can be advantageously used for the heating of a building when the heat / cold storage 1 configured as a wall element or integrated into a wall element, since thus a surface of the heat / cold storage 1 the interior of the Facing the building. Similarly, in a cooling operation, the heat input from the building in the heat / cold storage 1 is achieved.

To utilize an additional latent heat effect for energy storage, the embedding of the storage line 6 into the channel-like receiving recess 7 may include materials which undergo a phase transition at suitable temperatures, e.g. melting paraffin.

The heat / cold storage 1 can be combined with thermo-solar energy panels 16 (see FIG. 4). The solar heated storage liquid in the form of heat / cold fluid is passed directly into the heat / cold storage 1 and stored there with the heat contained. Through intelligent control of the various circuits in the thermal solar panels and in the Speichergehäuseverbunden 2 high efficiency can be achieved.

The heat / cold storage 1 can also be combined with photovoltaic panels. The power generated may be for direct or indirect heating (e.g., via a heat pump or via Peltier elements) or alternatively for cooling (e.g., via a heat pump or over cooling Peltier elements). When using Peltier elements, the combined generation of heat and cold in adjacent Speichergehäuseverbunden 2 is possible.

The heat / cold storage or generally energy storage 1, for example, with a local wind power tan läge be combined. The power generated can be used analogously to the above-explained photovoltaic variant.

The heat / cold storage 1 can also be integrated as a cold storage in the walls, floor and ceiling of a refrigerator / refrigerator. The wooden structures also serve as thermal insulators for the construction of the cold room / refrigerator. Thus, the cooling energy is locally and directly available for cooling the room. Losses to the interior of the room contribute to cooling.

In order to reduce the expense for an electronic control of the heat / cold storage 1, the following principle can be used: the inlet and outlet valves 13 are directly controlled by the heat status of the respective heating or cooling circuit, such. in the heating control conventional thermally controlled valve systems, which uses the thermal expansion effects for opening and closing the valves. At high temperature of the storage circuit, i. of the heat / refrigerant fluid in a storage line 6, the valve 13 is closed for the heat input more and more fully closed at a maximum desired storage temperature, opened at lower temperatures, however. [0048] A combination of two separate but adjacent storage enclosure interconnections 2 may be used as an electric power generator utilizing the Peltier / Seebeck effect. The Peltier elements are connected or integrated with the one side in a warmer storage enclosure 2 (e.g., heat storage) and the other on a cooler storage enclosure 2 (e.g., cold storage). Electric current can be removed at a sufficient temperature difference and processed by DC-AC or DC-DC converters in the desired manner.

A combination of two separate but adjacent storage enclosure interconnections 2 can be used as an electrical or mechanical power generator by means of a Sterling engine. The mechanical energy can be converted by a generator into electrical energy or used directly (for example, to drive a water pump or a ventilation fan).

For the sake of completeness, it is to be noted that the heat / cold storage 1 according to the first embodiment contains two storage housing assemblies 2 according to FIG. 1, which may be arranged adjacent to each other, but also spatially separated from each other. For a block-type heat / cold storage 1, it is preferable to combine two or more storage housing bundles 2 adjacent to one another in a flat manner. In a design of the heat / cold storage 1 as a wall or wall element, the storage housing bundles 2 contain more than two solid wood elements in which the respective storage line is integrated, and two or more storage housing bundles 2 are adjacent to the front, i. adjacent or spaced. In this respect, the person skilled in the art understands the representation of FIG. 1 and the above descriptions as a doctrine as to how a storage housing assembly 2 is to be designed in principle and readily understands the freedom of design with regard to the number of solid wood elements for constructing a storage housing bundle 2 and with regard to the number and arrangement of two or a plurality of storage case interconnections 2 for constructing a heat / cold storage 1.

2, a second embodiment of a storage enclosure 2 of a heat / cold storage 1 is illustrated in an exploded schematic view. Basically, the structure and the design possibilities are the same as in the first embodiment. The differences between the second and the first embodiment are in the number of solid wood elements and in the design and shape of the course of the memory line 6 and thus the corresponding extending channel-like receiving recess 7. The meandering course of the memory line 6 According to FIG. 1 in the second embodiment replaced a grid, as illustrated by the course of the channel-like receiving recess 7 shown in FIG. 2, a third solid wood element 15, the increased insulation of the storage line 6 in the solid wood element 3 to an environment out, which is advantageous if the heat / cold storage 1 forms a building exterior wall, then the Solid wood element 15 forms the outside towards the environment. The valves 13 and the manifold system 14 are omitted in FIG. 2 for the sake of clarity.

In Fig. 3 is a exploded schematic view of a third embodiment of a storage enclosure 2 of a heat / cold storage 1 is illustrated. Basically, the structure and the design possibilities are the same as in the first embodiment. The differences between the third and the first embodiment are in the number of solid wood elements and in the design and shape of the course of the memory line 6 and thus the corresponding extending channel-like receiving recess 7. The meandering course of the memory line 6 according to the first embodiment is in the third embodiment by a double spiral-like course of the memory line 6 is replaced. Finally, the storage housing composite 2 shown in FIG. 3 still has a third solid wood element 15, the increased insulation of the storage line 6 in the solid wood element 3 to an environment out, which is advantageous if the heat / cold storage 1 forms a building exterior wall, then the Solid wood element 15 forms the outside towards the environment. In an exploded schematic view, FIG. 4 illustrates a fourth exemplary embodiment of a heat / cold accumulator 1 with two storage housing interconnections 2. Similar to the second and third embodiments, in the fourth embodiment, in the first storage case assembly 2 shown below in FIG. 4, there is an additional insulating outer solid wood member 15. Further, on the free outer side of the solid wood member 15, a thermal solar panel 16 is provided. For a readily clear connection line from the thermo-solar energy panel 16 to the storage line 6, a passage 17 is provided in the thermal solar panel 16 and in the solid wood element 15. The second storage housing composite 2 is applied flat to the first storage housing composite 2 and contains only a first and a second solid wood element 3 or 4. The storage lines 6 of the two storage housing 2 are at their supply ends 11 and discharge ends 12 via the controllable valves 13 to the distribution system 14th connected or connectable.

Hereinafter, some advantageous and preferred embodiments are given and explained.

A heat / cold storage 1 as an inner wall or outer wall can be directly connected to a heating surface or a radiator (tubes with heat fluid or coolant embedded in eg clay plaster), so that, for example, a wall surface heating or cooling directly to the storing wall can be realized with the heat / cold storage 1.

Active thermal storage designated heat / cold storage 1 for heating and / or cooling can thus be prepared in an advantageous manner predominantly from renewable and recyclable raw materials. The layered structure with a combination of heat conduction, heat storage and insulation enables high efficiency. Further optimized efficiency is achieved by electronic temperature sensors and control of separate heating / cooling circuits via valves and pumps. Optionally, additional thermal insulation located outside and / or in intermediate layers of the heat / cold storage (s) 1, such as, for example, can be provided. Soft wood fiber material can be used.

A use of the heat / cold storage 1 as or in house inner walls (s) for the thermal storage has particular advantages in winter. A use of the heat / cold storage 1 as or in Hausau ßenwände (s) for the thermal storage has particular advantages in the summer. In hot climatic periods or zones can be achieved with the heat / cold storage 1 cold storage. An increased storage effect of the heat / cold storage 1 can be achieved by utilizing latent heat effects by co-embedding e.g. Paraffin elements are achieved.

For direct heating of the heat / cold fluid, a combination of the heat / cold storage 1 can be used with thermal solar panels. A combination of the heat / cold storage 1 with photovoltaic solar panels allows further direct or indirect heating via heat pump or Peltier effect. With this design, the generation of electrical energy from two combined Speichergehäuseverbunden 2 for heat and cold using Peltier / Seebeck elements is possible. A generation of mechanical and / or electrical energy can be obtained from two combined storage casings 2 for heat and cold by means of Stirling engines.

With the heat / cold storage 1 as a wall or wall element of a refrigerator / refrigerator cabinet, the insulating and simultaneously storing properties of the heat / cold storage 1 can be advantageously exploited. Similarly, a &quot; waste heat &quot; or a heat loss of the heat / cold storage 1 can be optionally used for an interior heating.

Advantageous for a low operating cost of the heat / cold storage 1 are self-controlling valve functions via thermally actuated valves. 7.13
