Definitions
- the invention relates to a heat-insulated storage tank according to the preamble of patent claim 1 and a method for designing a heat-insulated storage tank according to the preamble of patent claim 8.
- a heat-insulated storage container of the type mentioned is generally known per se, so that no special written proof is required.
- a heat-insulated storage container intended for holding heating circuit medium i.e. usually water
- a heat-insulated storage container intended for holding heating circuit medium (i.e. usually water)
- the thickness of the insulation layer that rests against and surrounds the wall of the storage container that has an inside and an outside is regularly specified. 25
- the object of the invention is to improve a heat-insulated storage container of the type mentioned at the outset.
- a storage tank with optimized thermal insulation is to be provided.
- This object is achieved with a heat-insulated storage container of the type mentioned by the features listed in the characterizing part of patent claim 1.
- the object is achieved by the features listed in the characterizing part of patent claim 8 . 5
- the insulating layer is made thicker in an area with an above-average temperature difference between the inside and outside of the wall than in an area with a lower temperature difference between the inside and outside of the wall, although it goes without saying here it is about a temperature difference that occurs during operation, in particular during stationary operation, of the storage container.
- the invention provides that an area of the wall with an above-average temperature difference between the inside and outside of the wall during operation of the storage tank is determined and a greater thickness of the insulation layer is defined in the determined area than in any other area of the wall.
- the storage tank according to the invention is characterized in that the thickness of the insulation layer is designed to be oriented to the heat flow through the wall 25 of the storage tank.
- different temperature differences can occur in different areas of the wall. These areas are optionally determined - which can be implemented by a person skilled in the art - by means of 30 practical tests or else by a computer simulation - which is necessary for a person skilled in the art with the appropriate knowledge simulation knowledge is also realizable.
- a particularly thick insulation layer is provided there in order to compensate for the temperature differences or to make them more uniform over the entire wall.
- a storage tank designed or designed in this way is thermally more favorable than one in which no account was taken of the areas in which there is a risk of particularly large temperature differences.
- the wall in the areas with an above-average temperature difference is designed to be concave on the outside and convex on the inside to accommodate the thicker insulation layer. This requirement also leads to a particularly pressure-resistant storage container.
- the storage tank be designed as a defrosting buffer or buffer storage of a heat pump (see, for example, the buffer storage according to DE 102018 25 102 670 A1) and in the housing of the heat pump itself, in particular a heat pump intended for installation inside a building.
- the storage container according to the invention which is or can be very compact due to its special design or shape, is particularly well suited for this purpose.
- the insulation layer is made thicker in the area or those areas where the inside of the wall is colder than the outside of the wall during operation of the storage container.
- an operating mode of the storage container is selected in which the inside of the wall is colder than the outside of the wall.
- thermally insulated storage container according to the invention and the method according to the invention for its design, including its advantageous developments according to the dependent patent claims, are explained in more detail below with reference to the graphic representation of a preferred exemplary embodiment.
- FIG. 3 shows the storage container according to FIG.
- the storage container shown in the figures initially consists, in a known manner, of a wall 110 forming the storage container, having an inside and an outside, and a wall 110 lying on the outside of the wall 1, enclosing the storage container and attached to different areas 1.1, 1.2 of the wall 1 insulation layer of different thicknesses 2.
- Said wall 1 preferably consists of a metallic material.
- the storage container preferably has a supply connection 3 and a discharge connection 4 (see in particular FIG. 2).
- a thickness of an insulation layer 2 lying against a wall 1 of the storage tank having an inside and an outside and surrounding the storage tank is defined in a known manner. 30 Objectively considered, it is now essential for the storage container according to the invention that the insulation layer 2 is thicker in an area 1.1 with an above-average temperature difference between the inside and outside of the wall 1 than in an area 1.2 with a lower temperature difference between the inside and outside of the wall 1 is formed.
- the insulating layer 2 is made thicker in the area 1.1 , on which during operation of the storage container 25 the inside of the wall 1 is particularly cold compared to other areas 1.2 and colder than the outside of the wall 1 or that to determine the above-average temperature difference in a (specific) area 1.1 (and in comparison to other areas 1.2), an operating mode 30 of the storage container is selected, in which the inside of the wall 1 is colder than the outside of the wall 1.
- the said temperature difference can be positive or negative depending on the mode of operation of the storage tank, ie cold outside and warm inside (e.g. heating mode of the heat pump) or warm outside and cold inside (e.g. cooling mode of the heat pump).
- the insulation layer 2 is at least so thick that the dew point is not undershot at any point on the wall 110 or condensation occurs.
