Detailed description of the figures 15 Turning to figure 1, a webbing or layer 10 of phase changing materials (pern) is shown. The phase changing material is provided as pills 12 which are encapsulated in a packaging material 14. The packaging material 14 provides a barrier layer around the pills and shields the pem from the surroundings. The packaging material 14 also interconnects the pills 12 via intermediate zones 16 which extend between the pills 12. The distance 20 between the pills 12 may vary, but a rather compact configuration provides a good volumetric efficiency. The pills 12 are also referred to as pem volumes 12 or packaged pem volumes 12.
The provision of the phase changing materials in relatively small, separate volumes provides a relatively large contact surface per volume, i.e. per unit of weight of the phase 25 changing materials. Between the pills 12, interconnected open spaces are provided through which a liquid or gas may flow.
The phase changing material may be any material known as such in the field of the art.
An example is a salt hydrate, in particular magnesium nitrate with graphite . The 30 melting range of this salt hydrate lies between 60 en 80 degrees Celsius. The salt is embedded in a polymer (Thermusol), wherein possible left open volumes are filled with graphite. This material is compressed into substantially hard pills 12. The pills are packaged into a blister padding (BiCell). This blister padding is known from the packaging industry.
Other examples may be paraffin, fatty acid.
35 The layer 10 of pem volumes is approximately 1 cm thick, i.e. between 0,5 and 2 cm.
The pills 12 are circular when seen from the front and a have a substantially uniform thickness. The pills have a substantially flat upper side and a substantially flat bottom side.
-5-
Turning to figure 2, a layer 10 of packaged pcm volumes 12 is shown together with a support structure 20 or support layer 20.
The support material which forms the support layer 20 is a wire mesh, or may be another kind of support material with an open structure. The wire mesh comprises horizontal 5 wires 38 and vertical wires 39.
The wire of the wire mesh can be made of steel or another suitable metal. The wire may be provided with a coating. The wire mesh has a relatively open structure and can be manufactured from twined thread.
The wire mesh and the layer of pcm volumes are rolled onto on another into a roll 24.
10 Once rolled, the combination of the layer of pcm volumes and the support layer 20 provides rigidity, in particular in the lengthwise direction. This allows the roll 24 to stand upright in such a way that the packaged pcm volumes 12 remain in position. Thus, although the layer 10 of pcm volumes in itself does not have substantial rigidity, the support layer 20 provides the rigidity when both layers are rolled onto one another.
15 It is also possible that sections of layers 10 of pcm volumes and sections of support layers 20 are cut and laid on top of one another. Instead of rolling, there may be alternatives to provide alternating layers 10 of pcm volumes and layers 20 of support material.
The forces of gravity are transferred onto the support structure 20 and carried downward via the vertical wires 38.
20 The forces are then transferred via the lower edge 41 of the support layer 20.
It is also possible that the wire mesh comprises predominantly diagonal wires.
The layer 10 of packaged pcm volumes 12 and the support layer 20 are rolled onto themselves, such that between each two layers 10 of pcm, a support layer 20 is provided.
In top view, the layer of packaged pcm volumes and the support layer from a double 25 spiral.
A height 23 of the layer 10 of packaged pcm volumes is smaller than a height 25 of the support layer 20. This has a result in that in a lower section 22 of the roll 24, there is no layer of packaged pcm volumes. This will be further discussed herein below.
Turning to figure 3, a thermal storage device 30 is shown. The thermal storage 30 device 30 is a container having a cylindrical form. The thermal storage device 30 has a height 32, a width 34 and a central axis 36. The thermal storage device 30 has an upper side 40, a lower side 42, and a circumferential wall 44. The thermal storage device has a housing 46, which defines an inner space 48. The housing 46 can be metal or plastic or another material, such as fiberglass. The housing 46 may a double wall construction having 35 standard insulation between the walls.
The thermal storage device comprises an inlet 50 and an outlet 52. The inlet 50 and outlet 52 are provided at the top of the housing 30.
-6-
The inlet 50 goes over in a tube 54 which extends from the top 40 of the housing to a short distance 55 from the bottom end 42 of the thermal storage device 30. Here, the tube 54 ends in an open end. The inlet is attached to the top 40 of the thermal storage device.
In the interior space 48, the layer 10 of pern volumes 12 and the layer 20 of support 5 material are provided as a roll 24 about the central axis 36. In side view, the layers 10 of pem extend vertically, and between each layers 10 of pem, a layer of support material is provided.
It is noted that the although the sectional view shows many layers 10 of pem volumes and many layers 20 of support material, since the layer 10 and the layer 20 are rolled onto 10 one another, there physically is only one layer 10 of pem volumes and one layer 20 of support material. As mentioned above, other layer arrangements than a roll are conceivable.
In a lower region 60 of the thermal storage device, there are no pem volumes 12 provided, but only the support structure. This region is called a mixing zone. A similar mixing zone 62 is provided at the top of the thermal storage device. Here, there also is no support 15 material.
The support material in the lower mixing zone 60 engages the bottom 42 of the thermal storage device 30.
At the lower side 42 of the thermal storage device 30, a coupling inlet 82 and a coupling outlet 80 are provided. The coupling inlet 82 and coupling outlet 80 are closed off 20 with caps 81,83. These will be explained further below.
Operation
Turning to figure 4A, a normal operation of the thermal storage device 30 is shown.
In use, the inlet 50 and the outlet 52 are coupled to a liquid or gas conduit system, 25 such as a heating system or a heat pump. This means that in use the layers 10 of packaged pem volumes are continuously immersed in the liquid or gas.
The liquid or gas is pumped into the inlet 50 and flows through the tube 54 to the lower mixing zone 60. Here, the liquid or gas spreads out and flows into the entire mixing zone 60. Next, the liquid or gas flows upward between the layers 10 of pem. The liquid or 30 gas flows through the layers of support material 20. The support material is a wire mesh, or may be another kind of support material with an open structure, which allows a liquid or gas to pass through. The liquid or gas also flows through the open spaces between the pills 12.
Thus, the support structure 20 has a double function of on the one hand supporting the pem volumes 12 and preventing the pem volumes 12 of sagging or collapsing under 35 theur own weight, and on the other hand creating an open structure which allows a liquid or gas to pass through.
-7-
The liquid or gas may exchange heat with the layers 10 of pcm volumes during this period. The liquid or gas flows from the lower mixing zone to the upper mixing zone 62.
If the liquid or gas is warm, it will give off its heat to the phase changing material and cool off. The phase changing material will take up the heat and become warmer. If the liquid 5 or gas is cold, i.e. colder than the temperature of the phase changing material, the liquid or gas will take up heat from the phase changing material and become warmer. The layer 10 of pcm will then gradually become colder.
Turning to figure 4b, it is possible to couple multiple thermal storage devices 30A, 30B with one another. This results in a thermal storage device having an increased capacity. 10 A feed line (IN) and an Out-line 72 both are branched off in order to be connected with two thermal storage devices 30A, 30B.
Modular units
Turning to figures 5A and 5B, another option for coupling multiple thermal storage 15 devices 30 is shown. The coupling outlet 80 and coupling inlet 82 are provided with caps 81, 83. These caps 81, 83 are removed.
A thermal storage device 30B is then coupled with of another thermal storage device 30A. The coupling outlet 80 of unit 30B is coupled to the inlet 50 of unit 30A and the coupling inlet 82 of unit 30B is coupled to the outlet 52 of unit 30A. The bottom side 42 of 20 the unit 30B engages the top side 40 of the unit 30A.
The tubes 54 of the two units 30A, 30B are coupled with one another. A small insert 86 may be required to provide this coupling.
It can be seen in figure 5B that the inlet 50 of the unit 30B is now coupled to two successive pipes 54 which extend all the way down to the lower mixing zone 60 of the 25 bottom unit 30A.
Operation A liquid or gas enters the combined thermal storage devices 30A, 30B via the inlet 50. The liquid or gas then flows through the tubes 54 down into the lower mixing zone 60 of 30 the lower unit 30B. Here, the liquid or gas starts flowing upward through the layers of supporting material between the layers 10 of pcm volumes 12. The liquid or gas also flows through the open spaces between the pills.
After the liquid or gas arrives in the upper mixing zone 62 of the unit 30A, it flows through the outlet 52 of unit 30A and the coupling inlet 82 of unit 30B into the lower mixing 35 zone 60 of the unit 30B. From here, the liquid or gas flows through the layers of support material of the upper unit 30B. Eventually, the liquid or gas arrives in the upper mixing zone 62 of the upper unit 30B.
-8-
From here, the liquid or gas flows outward through the outlet 52.
