Description

The invention relates to a component made of cement-bound materials for absorbing and storing environmental heat, with pipe coils embedded in the component and intended for the passage of a liquid or gaseous carrier medium for heating buildings by means of a heat pump, the component consisting of two firmly connected parts, and a method for producing this component.

Such components are e.g. described in DE-OS 30 35 538 by the same applicant.

According to the proposal of the aforementioned DE-OS 30 35 538, the components are integrated into the structure, the components located outdoors, i.e. e.g. External walls, balcony slabs or parapets, parapets, pilaster strips and the like, essentially the heat absorption and the components in contact with the earth, e.g. Floor and foundation plates that serve to store heat.

However, the measures proposed in DE-OS 30 35 538 can essentially only be implemented directly in the design and construction of new buildings.

However, in the course of energy-saving measures, there is also a considerable need for retrofitting buildings with heating systems that derive their energy from environmental heat.

5 The present invention has for its object to provide a prefabricated component of the type mentioned, with which a heating system working with a heat pump arrangement can be equipped without the component having to be directly integrated into the structure to be heated.

For this purpose, the component is designed in such a way that the part used to absorb heat is intended to be outdoors, so that it absorbs heat from the outside air flowing past, from the sun's rays and from Niels shock. Surface heat exchangers of this type are referred to as heat absorbers.

The second part, which is arranged as intended in the ground or in direct contact with the ground, stores heat when there is an oversupply of environmental energy in the interior of the storage component and in the adjacent ground and, if necessary, can release it to the heating system at a later time. It is a so-called cold store.

For certain purposes, it can be advantageous if the component is in one piece. According to another proposal, it can consist of two components that are subsequently assembled to form the component. Such components are recommended if they e.g. have to be transported over long distances. 30 Monolithic components are suitable for use as embankment angles, e.g. L-shaped or T-shaped in cross-section, with the L-shaped cross-sectional shape the vertical leg of the "L" can be used for heat absorption and the horizontal leg for heat storage.

The cross-sectional shape of an upside-down “T” is particularly suitable for the two-part design, the horizontal leg being used for storage and the vertical leg for heat absorption. With this component 40, e.g. make rows in the production of enclosure walls, whereby a mutual offset to bridge the butt joint is possible between the component parts.

It may also be expedient for the component 45 to be completely or partially closed, for example as a garage, the base plate of which forms the part for heat storage and the wall and roof areas of which serve to absorb heat.

It is also expedient if, in this component, the surfaces of the part designed for heat absorption, which are located outside in use, are structured in this way and / or are provided with a coating which increases the degree of absorption for short-wave radiation.

The invention further relates to a method for producing the component according to the invention, which is characterized in that the two parts are firmly connected to one another after separate production.

It is advantageous if, for the production of an L-shaped or T-shaped component with a cross section, the horizontally running part intended for heat storage having a continuous channel, the vertically running part intended for heat absorption, preferably on the construction site, into the Channel of the horizontally running 65 part is used.

The invention is explained below with reference to the drawing, for example. It shows:

embodiment of a component according to the invention;

2 shows a perspective illustration of a second exemplary embodiment of a component according to the invention;

3 shows a perspective section of a component which serves to absorb heat and has a surface structure which increases the surface area, and

Fig. 4-6 different circuit options of the circuits.

The “L” -shaped component according to FIG. 1 is particularly advantageous for production and retrofitting. It is monolithic, with pipe coils 10 and 21, indicated by dashed lines, embedded in its mutually perpendicular leg parts 10 and 20. This component can be used when retrofitting the heating system e.g. for embankment support, to form boundary walls and the like. The component is to be arranged in such a way that its horizontal leg part 20 is located in the ground below the surface 40 indicated by dash-dotted lines.

The second exemplary embodiment of the invention, which is illustrated in FIG. 2, is initially produced in two parts, which can be advantageous for production or transportation. In cross-section, it forms an upside down “T”. Its horizontal, heat-storing part 20 'is provided in the middle with a continuous channel 22' into which the leg part 10 'serving to absorb heat is subsequently inserted. This union can already take place in the manufacturing plant, but also on the construction site. This component is also to be mounted in such a way that the horizontal part 20 'is located below the earth's surface 40'. It can be used in the same way as the exemplary embodiment according to FIG. 1.

The surface of the parts used for heat absorption can, as indicated with FIG. 3, be structured in order to thereby increase the absorption capacity, that is to say the degree of heat absorption. Fig. 3 shows a component section 10 "with a cube structure 12" which e.g. can lead to a more than 4-fold increase in surface area compared to a flat surface. However, other structures such as corrugations are also suitable. Furthermore, it may be expedient to provide the surface with a coating which has a high degree of absorption for short-wave radiation, namely for thermal radiation. In the simplest case, this coating can be a coat of paint.

io In a manner not shown in the drawing, the prefabricated component itself can consist of a completely or partially closed structure, preferably a prefabricated garage, the bottom plate of which is used for heat storage and the wall and ceiling parts of which absorb heat.

The circuits 11, 11 'and 21, 21', which are only indicated schematically and are formed by the coils, are connected to the heat pump 30 or to one another, depending on the heat supply, heat requirement or storage state. Two or three switch positions are possible.

4, the heat pump 30 extracts the heat from the heat-absorbing part 10 via the circuit 11, raising the temperature level in a known manner and supplying the heating circuit (not shown) for space heating or process water preparation.

In the switching position according to FIG. 5, the heat pump takes over the heat energy stored in the part 20 serving for heat storage, which is made usable in the same way.

6, however, the circuits 11 and 21 of the parts 10 and 20 are connected in series via the circulating unit in the heat pump 30, the heat pump itself being out of operation. In this switch position, the heat absorbed by the component 10 is transported to the part 20 located within the soil for heat storage and stored there as well as in the ground.
