Description

The The invention relates to a buffer storage for the heat transfer medium a heat consumer according to the preamble of the protection claim 1.

Known are buffer tanks for the heat transfer medium a heat consumer, for example in the context of solar thermal Systems in which with solar collectors a heat transfer medium, especially water, can be heated, the heated Water is stored in the buffer tanks.

Known is it, cache in basements of houses to arrange, but with the disadvantage that the buffer memory, as they entered the cellar through the door must be either a size of 600 to 800 l can not exceed or disassembled in pieces disassembled by the cellar door placed in the corresponding cellar rooms and on site must be assembled.

The DE 20 2007 002 525 U1 discloses a buffer tank which is suitable for installation outside the house in the ground. The buffer described therein is in a waterproof plastic barrel, which is expensive to manufacture and also does not have sufficient stability for various applications.

The DE 20 2008 004 897 U1 discloses a buffer for the heat carrier of a heat consumer with a heat-insulating, load-bearing container casing made of concrete, which is filled in a permanent formwork on site.

The EP 1 132 691 B1 discloses a buffer for the heat carrier of a heat consumer with a load-bearing container and with a heat insulation between the container shell and a watertight heat transfer container.

The The object of the invention is an easy to install, stable buffer for the heat transfer medium a heat consumer for installation except To provide house in the ground.

The The object of the invention is achieved by a buffer memory with the features of the protection claim 1.

advantageous Embodiments and developments of the invention are specified in the subclaims.

Of the Inventive buffer memory for the Heat carrier of a heat consumer for the installation outside the house in the ground with a load-bearing Container and a watertight heat transfer container, between the container and the watertight heat transfer container an insulation is arranged, characterized in that the container is made of concrete, the container a container pan and a container cover having an opening and wherein the container trough and the container cover as a one-piece Element are formed. The buffer memory is thus considered a Finished part delivered and is directly out of the house in the ground Can be used without the concrete poured into a formwork on site must, which makes assembly much easier. The buffer will be off Concrete made to give the buffer a high stability to rent. In addition, the production of concrete is particularly cost-effective.

According to one particularly preferred embodiment of the invention the container formed pressure-retaining. This will in particular a direct connection of the buffer to a heat consumer, especially a heating system of a house, allows without a heat exchanger must be interposed. In particular, this is the container for pressures designed up to 3 bar.

According to one advantageous development of the invention is the heat transfer container Made of stainless steel, this way the buffer too for long-term installation.

Preferably is the heat transfer container as a film designed to be able to produce material saving.

According to one preferred embodiment of the invention is the opening Closable by a cover to the buffer completely opposite to the surrounding soil complete.

Of the End cover is preferably screwed onto the opening, a reliable connection between the end cap and container even under pressure in the interior of the container to ensure.

According to one preferred embodiment of the invention, the container a volume of more than 1000 liters but preferably less than 10000 l, so he has a suitable sizing for buffer memory of single or multi-family homes.

Preferably, the heat transfer container is on a in the interior on the bottom surface of the Be arranged rigid foam insulation arranged, whereby a smooth bearing surface is formed for the heat transfer container.

Favorable Way is the insulation between the heat transfer container and the container wall at least partially formed by a Blähtongranulat, which in a simple and cost-effective manner the space can be poured and good thermal insulation Features.

One Embodiment of the invention will be with reference to the following Figures explained. It shows:

1 a longitudinal section through an embodiment of a buffer memory according to the invention,

2 a longitudinal section through the container of the buffer memory according to 1 and

3 a cross section through the container according to 2 ,

1 shows a longitudinal section through a buffer memory 10 with a container 20 , a heat transfer container 30 and one between the innards 30 and the container 20 arranged insulation 40 , where in the 2 and 3 a longitudinal and a cross section of the container 20 are shown.

The container 20 has a container trough 21 with a bottom side 21a and a lateral surface 21b and a container cover 23 on. The container 20 is made of concrete, especially as a single one-piece element.

The container pan 21 is with the container cover 23 integrally connected, wherein in the manufacture of the buffer memory 10 the heat transfer container 30 with the container 20 is surrounded such that the buffer memory 10 subsequently available as a finished part, without the buffer tank 10 to be specially made outside the house in the ground. The cache 10 holds about 1000 to 10000 l and is thus dimensioned to serve as a buffer for a single or multiple dwelling. The cache 10 is used in the ground and can, because it is available as a finished part, can be used directly in the ground and connected without a costly installation, especially by on-site in formwork to be poured concrete, would be necessary.

The heat transfer container 30 is made of stainless steel and in particular made of stainless steel foil or designed as a stainless steel tank, wherein in the interior of the heat transfer container 30 the heat transfer medium, in particular water, is arranged. The heat transfer container 30 has water connections 32 on, to which water pipes 34 can be connected, which from the buffer memory 10 through an implementation 26 be led out.

The container cover 23 has an opening 24 on, which is dimensioned by the diameter such that the heat transfer container 30 not retrospectively through the opening 24 in the interior of the container 20 can be introduced. The opening 24 is for maintenance purposes only.

The container 20 is formed pressure-retaining. This is made possible in particular by the use of concrete as a material in the manufacture of the container 20 , the one-piece design of container tray 21 and container cover 23 as well as the small dimensioning of the opening 24 to the container 20 to give the necessary stability. Due to the pressure-retaining design of the container 20 it becomes possible the water pipes 34 To connect directly to a heating system of a house, without a heat exchanger must be interposed.

The opening 24 of the container 20 Can through a cover 27 be sealed, which in particular can be used via a thread to the pressure-retaining properties of the container 20 to ensure. In an embodiment, not shown in the figures, the implementation 26 for the water pipes 34 directly in the end cap 27 arranged. In the alternative embodiment shown in the figures is at the opening 24 first an intermediate piece 25 either integrally formed or attached via a thread. The intermediate piece is substantially tubular and substantially perpendicular to the top of the container 20 around the opening 24 arranged. In a lateral opening of the intermediate piece 25 is the implementation 26 formed, wherein the intermediate piece 25 up through the end cap 27 is completed.

In the interior of the container 20 is on the bottom side 21 a foam board 42 arranged to a flat support surface for the heat transfer container 30 to build. The space between the heat transfer container 30 and the lateral surface 22 and the heat transfer container 30 and the container cover 23 is with a Blähtongranulat 44 as insulation 40 refilled. Alternatively, the expanded clay granules 44 also in the area between the heat transfer container 30 and the bottom side 21 be arranged additionally. Is the heat transfer container 30 Under pressure, the pressure on the insulation 40 to the container 20 issued.

For example, the inner diameter the container trough 2 m, the outer diameter 2.24 m and the diameter of the opening 24 less than 1 m. The internal height of the container 20 is for example 1.9 m, the external height 2.11 m. The wall thickness of the lateral surface 22 is thus about 0.12 m, the wall thickness of the container cover 23 in the range of about 0.2 m.
