Definitions
- the invention relates to a heat accumulator, comprising a large-volume storage container for storing a storage medium, in particular hot water, and to processes for its production.
- a heat storage heat from a heat source such as a solar system
- record and store long term If necessary, the stored energy can be removed from the heat storage again and used, for example, for heating.
- a heat accumulator which comprises at least one storage container arranged in the ground, the storage container being formed from a pressure-resistant material and surrounded by a heat-insulating, pressure-resistant material.
- One way of designing heat accumulators is to construct the heat accumulators to include an inner container, an outer container, and a thermal insulation disposed between the inner and outer containers.
- the inner container is designed such that it withstands the internal pressure caused by the storage medium accommodated in the heat accumulator.
- the heat insulation is arranged without pressure around the inner container. Neither the heat insulation nor the protective outer shell serving as a protective cover take up a significant part of the internal pressure. The internal pressure is thus almost completely absorbed by the inner container.
- the inner container If the inner container is made of plastic, then it must have a very large wall thickness in order to have sufficient strength to withstand the internal pressure permanently.
- the thus required large wall thicknesses of the inner container are disadvantageous, since the weight of the heat accumulator is thereby increased, which makes handling difficult and transport costs are increased, higher costs incurred by the higher material consumption and thus the outer diameter of the heat accumulator is relatively large.
- the heat accumulator is intended for use in a house, its outside diameter may advantageously not exceed the standard door width of 79 cm.
- a large wall thickness thus causes the inner diameter of the heat tank is reduced and thus the maximum volume of the heat accumulator is limited. It is an object of the invention to provide a large-volume heat storage, which is inexpensive in construction and relatively easy to produce and can store heat efficiently over a longer period of time.
- the large-volume storage container of the heat accumulator comprises an inner container and an outer container, wherein the inner container made of a temperature-resistant thermoplastic material and the outer container is made of a pressure-resistant thermoplastic material. In a space between the inner container and the outer container, a pressure-resistant, heat-insulating material is arranged.
- the wall thickness of the outer container is greater than the wall thickness of the inner container.
- the outer container, the inner container and the heat-insulating material are designed in such a way that a pressure exerted on the heat accumulator is absorbed essentially by the outer container.
- a pressure exerted on the heat accumulator is, in particular, an internal pressure exerted by the storage medium accommodated in the heat accumulator.
- an external pressure can act on the heat accumulator. This is particularly the case when the heat storage is absorbed in the soil and is not or only partially filled with a storage medium.
- the plastic from which the outer container is formed is suitable to be received in the ground.
- the heat storage can be arranged to save space in the ground.
- a particular advantage of the heat accumulator according to the invention is that the storage container can be produced in a particularly simple and inexpensive manner, since the production of the storage container, which is to be formed from a low-cost, thermoplastic material can be done in a relatively easy to carry out B las molding process.
- the storage container substantially in the form of a sphere, an ellipsoid of revolution or a cylinder.
- the spherical shape when used in the soil to choose because due to the ratio of surface area to volume, the ball the least heat loss can be expected and the ball can demonstrate a high compressive strength at the same time.
- the temperature-resistant plastic of the inner container is preferably polypropylene (PP) or polyethylene (PE), since PP or PE has a heat resistance up to 95 ° C and is thus adapted to the temperature conditions of the storage medium, if the inner container, for example, for receiving of hot water is used.
- PP polypropylene
- PE polyethylene
- the pressure-resistant plastic of the outer container is preferably polyethylene (PE), a thermosetting plastic or a plastic reinforced with glass fibers (GRP).
- the heat-insulating, pressure-resistant material of the intermediate layer between the outer container and the inner container is a rigid foam, preferably polyurethane (PU) 5 since polyurethane may have a strength which is in the pressure conditions in the inner container, which are in the range of 100 to 200 kPa , is adjusted
- the outer container comprises at least a first part and a second part. It is particularly advantageous if these parts have a maximum dimension in a direction smaller than 79 cm, for example each maximum 79 cm long. In this way, the parts of the outer container can be easily transported through a standard door with a width of 79 cm. Due to the structure of the outer container of several parts, a larger filling volume of the heat accumulator can be realized and this heat storage can still be easily transported into interiors.
- Another aspect of the invention relates to a method for producing a large-volume storage element for storing heat energy, in which an inner container made of thermoplastic material is produced in a blow molding process.
- an outer container with a larger diameter than the inner container made of thermoplastic material In a further blow molding process, an outer container with a larger diameter than the inner container made of thermoplastic material.
- the outer container is divided into at least two parts. These parts are arranged at a predetermined distance from the outer surface of the inner container with a gap therebetween. Subsequently, the parts of the outer container are interconnected and the space between the inner container and outer container is filled with plastic foam material.
- a further aspect relates to a further method for producing a large-volume storage container for storing heat energy, in which in a blow molding process, an inner container made of thermoplastic material and in a further blow molding at least two parts of an outer container with a larger diameter than the inner container made of thermoplastic material , On the inside of the parts of the outer container, which faces the inner container in the assembled state, a layer of plastic foam material is applied in each case in a foaming process, which is dimensioned such that an intermediate region between the inner container and the outer container is at least partially filled by this layer.
- the parts of the outer container are arranged around the inner container and then connected to each other.
- the parts of the outer container are preferably connected to each other via at least one screw connection formed by at least one external thread and at least one internal thread.
- the threads can be easily formed during the manufacture of the parts in the blow molding process. Furthermore, such a screw connection when disassembling a heat storage can be solved non-destructive.
- the parts of the outer container may be interconnected by a clamping ring.

- FIG. 1 shows, in a simplified sectional representation, a spherical heat accumulator 10 with a storage container 12, which comprises an inner container 14 and an outer container 16.
- the storage container 12 is arranged in this example in use in the ground.
