[0001] The subject of the invention is a Device for storage of energy, in particular cooling
energy, and the method of cooling the device for storage of energy, in particular
cooling energy, as well as the specific use of the device for storage of energy. The
invention is applicable to cyclic freeze-up, i.e. the generation and build-up of ice
and its use for refrigeration purposes, when there is an increased demand for cooling
power in systems, such as air conditioning or freezing. The application may also include
refrigeration or freezing devices that do not operate permanently, but the time and/or
duration of their use requires an additional supply of cold that cannot be obtained
during standard operation of such equipment. The solution is a particular development
of a previously filed invention for protection under number P.439045, under the same
title.
[0002] Devices for making and maintaining a permanent layer of ice are known to the general
public. The systems used for this are, as a rule, heat exchangers, where the principle
of refrigerant circulation is a pipe system, more or less extensive, in the form of
pipe serpentines, with additional pipe connections. The systems may additionally have
a manifold and a dedicated number of valves.
[0003] A device using a similar principle of operation, in particular the circulation of
the refrigerant through the interior of the piping system, is the ice-making and ice-storage
device described in
Polish Patent No. Pat.235695. A known solution reveals an arrangement of two pipe heat exchangers that overlap,
being connected by flow channels. The ice mass builds up on the outside of the pipe
system arranged in this way.
[0004] From the
Polish patent number Pat.207416, a cascade, two-stage refrigeration system is known, containing a thermoelectric
module of a high-temperature cooling stage, thermoelectric modules of a low-temperature
cooling stage, an interstage cold accumulator and a flow heat exchanger. The interstage
cold accumulator consists of two horizontal plates - heat exchangers - upper and lower,
separated by a working agent, where the upper exchanger has a concave, conical or
spherical inner working surface, and the lower exchanger has a convex inner working
surface. Both exchangers are mounted in the body and set coaxially with respect to
each other and the body. The exchangers are mounted in a body filled with a working
fluid, made of a material with low thermal conductivity, and they are arranged coaxially
with respect to each other and the body. The working fluid, as a rule, is designed
to freeze over and produce ice from it, which builds up between the plate top and
bottom exchangers. The method of operation of the interstage cold accumulator known
from this patent is that continuous thermal contact between the ice and the low-temperature
stage is maintained, and the operation of the high-temperature stage is carried out
in a cyclic cooling-heating mode, and the ice is cyclically formed in the form of
layers, and between freezing cycles, thermal de-icing of the formed ice layer is carried
out until the beginning of its ascent, ensuring its ascent before the melting of the
previous ice layer is completed.
[0006] For exchangers that are intended as cold accumulators in which the refrigerant, either
liquid or gas, flows through a pipe system, the ice is frozen up outside this pipe
system, and builds up around each pipe starting from the immediate vicinity of the
pipe around which the water being frozen-up is located. Then, the ice being frozen-up
usually increases in volume at a slower and slower rate, because, as it moves away
from the pipe, and therefore away from the refrigerant flowing through the pipe, its
impact on the water surrounding the pipe system decreases. The role of the chilling
agent is taken on by the ice that has already formed around the pipe. Cold propagation
therefore decreases with the passage of time, hence the rate of freezing up of the
ice in the exchanger also decreases. Notwithstanding the inconvenience of decreasing
the rate at which water is converted into ice, the unfavourable temperature distribution
in the tank containing the water to be converted into ice may be increased, of which
this generally applies to temperature irregularities at specific but different points
in the water tank due to circulation obstacles. This can further slow down the build-up
of ice.
[0007] In view of the above-mentioned structures, as well as the methods of cold accumulation
disclosed by their design, and also in view of the prior invention applied for legal
protection under No. P.439045, it has become apparent that it is possible to improve
the claimed invention, thereby ensuring both the security of a uniform ice build-up
over time, and a reproducible and precisely time-predictable method of this build-up
will be ensured, which method translates into long-term constancy of the parameters
and operation of the system, with the possibility of significantly accelerating the
processes of cold accumulation and recovery, and even extending these possibilities
and speed by carrying out both the build-up and recovery of cold from the accumulated
ice carrier at the same time. All of these processes will maintain a low probability
in terms of service needs due to plant damage, whether mechanical or process, or service
needs due to the high frequency of replenishment of utilities in the plant.
[0008] This is achieved with the device according to the present invention, which combines
the possibility of using an unexpected refrigerant circuit with respect to previously
known solutions, with methods already known and used previously. As a general rule,
such a combination was not known, either in terms of construction, process or specific
application according to the present invention.

[0048] A method of cooling the device for storage of energy according to the present invention,
in particular cooling energy, in which device continuous thermal contact between the
water being transformed into ice , i.e. for its liquid and solid states of aggregation,
and the refrigerant supplying the cold, via a thermal conductor is maintained, and
the transformation of water from its liquid state to its solid state of aggregation
and vice versa is carried out in a cyclic mode, wherein one from water to ice when
accumulating cold, and one from ice to water when discharging the cold, is based on
the fact that ice is formed during accumulation first in the immediate vicinity of
the thermal conductor, in the vicinity of which the refrigerant flows tangentially.
Water in both its liquid and solid states of aggregation, constituting a cold accumulator
bounded externally in each case by a first mantle made of a thermal conductor, is
thermally contacted and held on the inside of each first mantle which is previously
filled with it. When cooling the cold accumulator, once ice has been formed in the
immediate vicinity of the first mantle, in the form of a ring similar in size, but
with a smaller axial dimension in relation to the first mantle, it is further cooled
down by producing ice axially towards the inside of the cold accumulator while at
the same time producing successive layers of ice with successively smaller axial ring
dimensions in relation to the axial size of the first mantle of the individual cold
accumulator. The cold is supplied to the cold accumulators by washing over their first
mantles from the outside with liquid refrigerant collected and flowing as a free stream
through the tank. It is beneficial to force the circulation of this stream. At least
one cold accumulator is cooled down in one tank, and the refrigerant is maintained
in a liquid state of aggregation and at a temperature above its freezing point, preferably

with refrigerant by passing the refrigerant through this second mantle located inside
the cold accumulator, whereby said refrigerant is supplied and said refrigerant is
discharged from the exterior of the cold accumulator by means of a tubular inlet and
a tubular outlet respectively, supplying the second mantle from the freezing thermal
circuit.
[0049] Preferably, the ice is formed in the immediate vicinity of the second mantle, in
the form of a ring similar in size but with a larger axial dimension relative to the
second mantle, and it is subsequently cooled down by producing ice axially towards
the outside of the cold accumulator while producing successive layers of ice with
successively larger axial ring dimensions relative to the axial size of the second
mantle of the individual cold accumulator
[0050] Preferably, for every 1m
3 of volume of all cold accumulators cooled in the tank, between 0.01m
3 and 0.9m
3 of refrigerant operating in the tank outside the first mantles of the cold accumulators,
respectively, is used to cool them down.
[0051] Preferably, the temperature of the refrigerant is kept at a constant lower than -1°C,
preferably lower than -6°C.
[0052] Preferably, the refrigerant is supplied to the tank and/or to the inside of the second
mantle after cooling, preferably by pipes, with the supplied refrigerant being discharged
through a supply pipe after cooling and the supplied refrigerant being discharged
through a discharge pipe after use.

mantle during the cooling process, i.e. on an ongoing basis with simultaneous stream
exchange.
[0054] Preferably, refrigerant cooling is carried out in an external, self-contained heat
exchanger, operating for the purposes of the cooling process of the cold accumulators.
[0055] Preferably, the circulation of the liquid refrigerant is forced by a circulating
pump and/or an impeller equipped with blades.
[0056] Preferably, the forcing of the liquid refrigerant through the tank and/or through
the interior of the second mantle is carried out by a laminar flow, preferably at
a later stage of the process.
[0057] Preferably, the forcing of the liquid refrigerant through the tank and/or through
the interior of the second mantle is carried out by a turbulent flow, preferably at
an early stage of the process.
[0058] Preferably, the stream washing over the first mantles of the cold accumulators flows
through the tank along a serpentine path, using the spaces between the vertical baffles
and/or the spaces between the horizontal baffles and/or the spaces between the inner
inserts and/or the outer inserts and/or the openwork spaces.
[0059] Preferably, an aqueous solution of glycol or brine or alcohol or a solution thereof
is used as a refrigerant.
[0060] Preferably, the first mantle on the inside and the second mantle on the outside are
filled with water in an amount of no more than 90% of the volume of the spatial solid
of the first mantle.
[0061] Preferably, the freezing up of the ice during cold accumulation is carried out by
means of ice micro-radicals, preferably freely moved and/or stationary in the first
mantle and/or in the water filling thereof, using a volume amount of ice micro-radicals
preferably not exceeding 5% of the volume of the first mantle.
[0062] Preferably, up to 100 cold accumulators are used in a single tank, limiting them
spatially on the outside by their own first mantles and on the inside by their own
second mantles, their position relative to the tank and to each other being determined
by embedding the first mantles in the tank through internal spacer inserts and external
spacer inserts.
[0063] Preferably, between 15,000kJ and 15,000,000kJ of cooling energy is accumulated in
all cold accumulators operating in a single tank.
[0064] Preferably, a pressure of between 1atm and 6atm is maintained in the tank and/or
cold accumulators and/or inside the second mantle.
[0065] The application of the device for storage of energy, in particular cooling energy,
with cyclic freeze-up, i.e. the generation and build-up of ice, wherein the device
and/or the method shown above is used, is characterised in that during the cold accumulation,
i.e. during the transformation of water into ice, the same device is used for discharging
the cold, i.e. water is simultaneously obtained from the accumulated ice during the
reverse transformation.
[0066] Preferably, cooled refrigerant with a temperature of less than 0°C is used to supply
the cold, and it is supplied to the outer environment of the first mantle, while previously
used and now heated refrigerant with a temperature of more than 0°C is used to recover
the cold, and it is supplied to the inner environment of at least one of the second
mantles.
[0067] Preferably, the first mantle is used to build up ice in the cold accumulator, and
at least one second mantle is used to melt the ice.
[0068] Preferably, cooled refrigerant with a temperature of less than 0°C is used to supply
the cold, and it is supplied to the inner environment of at least one of the second
mantles, while a previously used and now heated refrigerant with a temperature of
more than 0°C is used to recover cold, and is supplied to the outer environment of
the first mantle.
[0069] Preferably, at least one second mantle is used to build up ice in the cold accumulator,
and the first mantle is used to melt the ice.
[0070] Preferably, conducting the transformation in a cyclic mode, preferably daily, periodic
intervals of simultaneous operation are used, during which the device is used in either
standard process accelerator mode of accelerated full accumulation or accelerated
full discharge, respectively, and during these periodic intervals a hybrid mode is
used.
[0071] The advantages according to the inventions are as follows:
- thanks to inventions in design and handling, the cold accumulator battery unexpectedly
freezes very quickly, and the refrigerant is not blocked from flowing, which has an
impact on the performance of the bed;
- the bed is used when there is an increased demand for cooling and regenerated by freezing,
with a reduced demand for cold transferred to downstream tasks;
- this appears to be the best possible solution, and thus much more precise in its applications
than currently known technologies;
- additionally and unexpectedly, thanks to the switching sequence, the system can be
adapted in advance to a predefined application under strictly defined conditions;
- above all, however, for the given operating parameters of the device, thanks to the
uninterrupted process of cooling and accumulative freezing up of the ice, it is possible
to calculate both the necessary process time and the accumulated cold in the form
of ice quite precisely - because the ice obtains a precisely designed volume, it does
not block the flow of the refrigerant in any way, which also precisely operates at
a given temperature around the mantles of the ice accumulators, i.e. the cold accumulators;
knowing the conductivity of the mantles, the cold supplied by the refrigerant transfers
its cooling potential to the ice which will remain in anticipation due to the hermetic
pressure and/or pressure-free structure of the tank and the ice accumulators; the
amount of cold that can be discharged will not be insufficient, as the threshold of
confidence in the accumulation achieved by the device and the method according to
the present invention will be significantly increased.
[0072] An unexpected advantage of the solution according to the invention is also the possibility
of using the same design of heat accumulation device with an appropriately selected
refrigerant and a substance crystallising due to phase transformation, in which case
the cycle can be carried out using accumulation and discharge temperatures other than
those for the cold respectively.
[0073] After exemplary realisations of the solution according to the invention, it has been
confirmed that the advantages of the invention make it possible to achieve an extremely
high and reproducible, and rapidly realisable performance of the bed comprising cold
accumulators, namely between 320,000 and 360,000 kJ/m
3 of such an accumulation bed.
[0074] The solution is illustrated in the manufacturing example, also in the drawing in
which Fig. 1 depicts the device of the first manufacturing example from above and
in profile along the long wall of the tank, in light cross-section of the walls revealing
the contents of the tank, Fig. 2 shows the device of the second example made from
above and in profile along the long wall of the tank, in light cross-section of the
walls revealing the content of the tank, wherein only the main differences of the
structure with respect to the first example are shown, without depicting the elements
that have not been changed and might not be identifiable due to the multiplicity of
mantles, Fig. 3 is a schematic representation of the refrigerant circuit of the structure
of the third example and its particular use of the hybrid mode, together with the
shown valves and their settings, through which the first and the second mantles are
connected to the refrigerant circuit of the whole system, so that for the accumulation
of ice in the cold accumulators the first mantles are used, and for the melting of
the ice the second mantles are used, while Fig.4 depicts schematically the refrigerant
circuit for the structure of the third example and the particular use therein of the
simultaneous mode, that is, for the mode of accelerator of standard processes, this
time of accelerated full accumulation without the participation of the cooling energy
receiver, together with the shown valves and their settings, through which the first
mantles and the second mantles are connected to the refrigeration circuit of the whole
system so that for the ice build-up in the cold accumulators both the first mantles
and the second mantles are used at the same time, which is in accordance with the
method of the first example described in more detail, and finally Fig. 5 depicts schematically
the refrigerant circuit for the structure of the third example and the particular
application therein of the simultaneous mode, i.e. for the standard process accelerator
mode, this time of accelerated full discharge without the involvement of the chiller,
together with the valves shown and their settings, through which the first and second
mantles are connected to the refrigerant circuit of the entire system so that both
the first mantles and the second mantles are used at the same time to melt the ice
in the cold accumulators.
[0075] The exemplary device for storage of energy, in particular cooling energy, is equipped
with the tank 1, the circulating pump 2 and the heat exchanger 3 of which heat exchanger
at least one cold accumulator 4 located in the tank 1 is a component. It is powered
in terms of refrigeration by the cooling liquid refrigerant 5 which is a carrier of
the cold. At least one cold accumulator 4 is placed in the tank 1, this time there
are precisely two of them, and each one is bounded by the mantle 6 in the form of
a spatial solid made of a thermal conductor, which spatial solid is filled with water
7 and an air buffer supplementing up to 100% of this filling. The mantles 6 of the
multiplied cold accumulators 4 are inseparably and at a distance connected to the
tank 1 and to each other, of which at a distance with respect to the walls 12 of the
tank 1 and with respect to the adjacent mantles 6, while directly with respect to
the bottom 13 of the tank 1 this time by their lower bases, and the distance between
the mantles 6 of the adjacent cold accumulators 4 ranges from 2mm to 150mm, this time
150mm. The tank 1 is filled with liquid refrigerant 5 as a cold carrier, which refrigerant
5 forms the surroundings of all mantles 6 of the cold accumulators 4 located in the
tank 1. The mantles 6 are incompletely submerged in the liquid refrigerant 5, this
time the refrigerant 5 washes over them up to 90% of their height, while the liquid
refrigerant 5 simultaneously constitutes the freezing thermal circuit of the cold
accumulators 4 bounded by their mantles 6. The mantle 6 surrounding each cold accumulator
4 is the first mantle 6' of that cold accumulator 4, while inside the first mantle
6', at a distance therefrom, but by means of the metal thermal bridges 34, being this
time and each time the bottom 34' and the cap 34" of the cold accumulator 4 to be
formed, there is the second mantle 6" of the same cold accumulator 4, wherein the
outer environment of the second mantle 6" is the cold accumulator 4, and the inner
environment in the kind of filling of the second mantle 6" is the refrigerant 5 supplied
and discharged by the second mantle 6" from the outside of the cold accumulator 4,
wherein the second mantle 6" has a tubular input 33' and has a tubular output 33"
connecting the second mantle 6" to the freezing thermal circuit.
[0076] The volume of tank 1 is no more than twice the volume of all the mantles of the first
mantles 6' of the cold accumulators 4 embedded in it, this time being 1.99 times,
while for every 1m

3 and 0.9m
3 of refrigerant 5, this time precisely 0.9m
3. The liquid refrigerant 5 constituting the freezing thermal circuit of the cold accumulators
4 bounded by their mantles 6', 6" is directed by valves 29, at least one pair of valves
29, and preferably even three pairs of valves 29, this time three. The circulation
pump 2 is permanently fixed in the tank 1, inside it on the side wall 12, being connected
to the tank 1 by a screw connection. The tank 1 is fitted with the single impeller
14 having helically mounted profiled blades 15, and it is fixed permanently but adjustable
inside the tank 1, forcing the refrigerant 5 to circulate omnidirectionally relative
to the tank 1. The tank1 is openable from the top, and is fitted with the lid 16,
the lid 16 being attached to the tank 1 via the flexible stub pipe 17. One outer spacer
insert 18 is provided between each first mantle 6' and the tank 1, at the bottom of
the tank 1 and halfway up the tank 1, and they are connected to the tank 1 and the
first mantles 6' at the bottom of the tank 1 inseparably, and at the halfway up the
tank 1 disjointly. Between the adjacent first mantles 6' of the cold accumulators
4 there is at least one inner spacer insert 19, this time two, one at ¼ of the height
of the tank 1, and the other at % of the height of the tank 1, and these are connected
to the first mantles 6' disjointly. The inner spacer inserts 19 are openwork, while
the outer spacer insert 18 located halfway up the tank 1 is solid. The tank 1 is provided
with at least one vertical baffle 20, this time in two, attached by its bottom edge
to the bottom 13 of the tank 1, and at most by its one lateral edge to the side wall
12 of the tank 1, both of these vertical baffles 20 being arranged in the tank 1 alternately,
with an offset one with respect to the other by being attached to the opposite side
walls 12. The tank 1 is in the form of a cuboid with a rectangular bottom, and the
6', 6" spatial solid mantles are cylinders with a circular bottom. The spatial solids
of the first 6' mantles have a closed top base, and each is equipped with a filling
valve 22 and a vent valve 23. The second 6" mantles are pass-through, i.e. they are
open on both sides to the refrigerant circuit 5. The bottoms of the spatial solids
of the first mantles 6', which are their lower base, are also a section of the bottom
13 of the tank 1. The spatial solids of the first mantles 6' and the second mantles
6" are placed vertically, coaxially, in the tank 1. The spatial solids of the first
mantles 6', in their cross-section, have a longest diagonal no longer than 60cm, this
time 40cm. The spatial solid of the second mantle 6" in its cross-section has the
longest diagonal no longer than 10cm, but no longer than 25% of the length of the
diagonal of the first mantle, this time it has precisely 10cm. The spatial solids
of the first mantles 6', in their longitudinal cross-section, have a longest diagonal
no longer than 300cm, this time 50cm. The spatial solid of the second mantle 6" in
its longitudinal cross-section, usually has the longest diagonal no longer than 95%
of the length of the longitudinal diagonal of the first mantle 6', preferably no shorter
than 50%, this time it is 45cm. The wall thickness of the first mantle (6') and the
second mantle (6") is no greater than 4mm, this time precisely 4mm. The first mantles
6' on the inner side are fitted with 24 rod tabs to increase the inner surface area
of the first mantle 6'. In the first mantles 6', on their inner side, the cores 25
are mounted, spaced from the side wall 12, vertically, being non-absorbent, but highly
flexible, which are compensators for the pressure force of the cold accumulator 4
in its phase transformation. In addition, in the first mantles 6', on their inner
side, the inserts 26 are mounted, horizontally sliding, non-absorbable but strongly
elastic, which are compensators for the evaporative force of the cold accumulator
4 in its phase transformation, and their number is multiplied to at least two, this
time three, and starting from the second one they are distributed in the first mantle
6' at distances from the upper base and the lower base in proportion, the first one
being fixed on the base of the lower spatial solid of the first mantle 6'. The tank
1 is a sealed pressure chamber with one sealing insert 27, which is also a spacer
insert. The tank 1 is lined with thermally insulating material, and the refrigerant
5 is an aqueous glycol solution. The first mantle 6' is filled with the water 7 in
an amount of no more than 90% of the volume of the space body of the first mantle
6', that is, at the same time, outside the second mantle 6", this time precisely 90%.
The first mantle 6' is also filled internally with the micro-radicals 28 of the ice
7', freely displaced in the first mantle 6' and in the water 7 constituting its filling,
the volume amount of the micro-radicals 28 of the ice 7' not exceeding 5% of the volume
of the spatial solid of the first mantle 6', this time not exceeding 3%. In one tank
1, all of the cold accumulators 4 arranged therein in their own mantles 6',6", seated
in the tank 1 by means of the internal spacer inserts 19 and the external spacer inserts
18, are arranged so that the inserts are elements which fix the position of the cold
accumulators 4 with respect to the tank 1, and with respect to each other. Exemplary
method of cooling the device for storage of energy, in particular cooling energy,
in which device continuous thermal contact between the water 7 being transformed into
the ice 7', i.e. for its liquid and solid states of aggregation, and the refrigerant
5 supplying the cold, via a thermal conductor is maintained, and the transformation
of the water 7 from its liquid state to its solid state of aggregation and vice versa
is carried out in a cyclic mode, wherein one from the water 7 to the ice 7' when accumulating
cold, and one from the ice 7' to the water 7 when discharging the cold, is based on
the fact that the ice 7' is formed during accumulation first in the immediate vicinity
of the thermal conductor, in the vicinity of which the refrigerant 5 flows tangentially.
The water 7 in both its liquid and solid states of aggregation, constituting the cold
accumulator 4 bounded externally in each case by the first mantle 6' made made of
a thermal conductor, is thermally contacted and held on the inside of each first mantle
6' which is previously filled with it. By cooling the cold accumulator 4, once the
ice 7' has been formed in the immediate vicinity of the first mantle 6' in the form
of a ring similar in size but with a smaller axial dimension relative to the first
mantle 6', it is further cooled by producing the ice 7' axially towards the inside
of the cold accumulator 4 while at the same time producing successive layers of the
ice 7' with successively smaller axial ring dimensions in relation to the axial size
of the first mantle 6' of the individual cold accumulator 4. The cold is supplied
to the cold accumulators 4 by washing over their first mantles 6' from the outside
with the liquid refrigerant 5 collected and flowing as a free stream through the tank
1. At least one cold accumulator 4 is cooled down in one tank 1, this time two, and
the refrigerant 5 is maintained in a liquid state of aggregation and at a temperature
above its freezing point, keeping the refrigerant 5 essentially at a constant temperature,
but the temperature of the refrigerant 5 is simultaneously maintained as less than
0°C. The cold is additionally supplied to the cold accumulator 4 by washing over the
interior of at least one second mantle 6" of the same cold accumulator 4 with the
refrigerant 5 by passing the refrigerant 5 through this second mantle 6" located inside
the cold accumulator 4, whereby said refrigerant 5 is supplied and said refrigerant
5 is discharged from the exterior of the cold accumulator 4 by means of the tubular
inlet 33' and the tubular outlet 33" respectively, supplying the second mantle 6"
from the freezing thermal circuit. The ice 7' is formed in the immediate vicinity
of the second mantle 6", in the form of a ring similar in size but with a larger axial
dimension relative to the second mantle 6", and it is subsequently cooled down by
producing the ice 7' axially towards the outside of the cold accumulator 4 while producing
successive layers of the ice 7' with successively larger axial ring dimensions relative
to the axial size of the second mantle 6" of the individual cold accumulator 4 This
is a simultaneous operation mode, during which the device is used in process accelerator
mode: accelerated full accumulation or accelerated full discharge, respectively, this
time accelerated cold accumulation in the form of the ice 7'. However, this is not
the only mode in which the device can be used. An example of this will be the hybrid
mode described below, occurring between consecutive simultaneous modes. For every
1m
3 of volume of all cold accumulators 4 cooled in the tank 1, between 0.01m
3 and 0.9m
3 of the refrigerant 5 operating in the tank 1 outside the first mantles 6' of the
cold accumulators 4, this time precisely 0.9m
3, respectively, is used to cool them down.
[0077] This time, the temperature of the refrigerant 5 is kept at a constant lower than
-1°C, and more precisely at -2°C. The refrigerant 5 is supplied to the tank 1 and
to the interior of the second mantle 6" after cooling down, by means of pipes, whereby,
after cooling down through the supply pipe 10', and after use, the supplied refrigerant
5 is discharged through the discharge pipe 10", where flow directions and temperature
of the flowing refrigerant 5 depends on whether the device is currently operating
in the accelerated accumulation mode, in the accelerated discharge mode or in the
hybrid mode, which depends on the settings of the valves 29. The refrigerant 5 is
supplied, as mentioned above this time during accelerated cold accumulation, to the
tank 1 and to the inside of the second mantle 6" also during the cooling process,
i.e. on an ongoing basis, with simultaneous stream exchange, and the cooling of the
refrigerant 5 is carried out in an external, independent heat exchanger operating
for the cooling process of the cold accumulators 4. The circulation of the liquid
refrigerant 5 is forced by the circulation pump 2 and the impeller 14 equipped with
the blades 15. The forcing of the liquid refrigerant 5 through the tank 1 and through
the interior of the second mantle 6" is carried out with a laminar flow, while this
occurs at a later stage of the process, and at an early stage of the process the forcing
of the liquid refrigerant 5 through the tank 1 and through the interior of the second
mantle 6" is carried out with a turbulent flow. The stream washing over the first
mantles 6' of the cold accumulators 4 flows through the tank 1 in a serpentine and
simultaneously spiral path, using the spaces between the vertical baffles 20 and the
spaces between the horizontal baffles 21 and the spaces between the inner inserts
19 and the outer inserts 18 and the openwork spaces. An aqueous glycol solution is
used as the refrigerant 5. The first mantle 6' from the inside and the second mantle
6" from the outside are filled with the water 7 to an amount of no more than 90% of
the volume of the spatial solid of the first mantle 6', this time precisely 90%. The
freezing up of the ice 7' during cold accumulation is carried out by means of micro-radicals
28 of the ice 7' freely moved in the first mantle 6' and in the water 7 filling thereof,
using the volume amount of micro-radicals 28 of the ice 7' preferably not exceeding
5% of the volume of the first mantle 6', this time 3%. Up to 100 cold accumulators
4 are used in the single tank 1 limiting them spatially on the outside by their own
first mantles 6', and on the inside by the second mantles 6", this time 2 each, their
position relative to the tank 1 and to each other being determined by embedding the
first coats 6' in the tank 1 through the internal spacer inserts 19 and the external
spacer inserts 18, and the second mantles 6" axially in the first mantles 6'. Between
15,000kJ and 150,000,000kJ of cooling energy is accumulated in all cold accumulators
4 operating in the single tank 1, but this time only 21,600kJ.
[0078] The pressure in the tank 1 and in the cold accumulators 4 is maintained in the range
from 1atm to 6atm, this time precisely corresponding to the atmospheric pressure.
[0079] An exemplary application of the device for storage of energy, in particular cooling
energy, with cyclic freeze-up, i.e. the generation and build-up of the ice 7', wherein
the device and/or the method shown above is used, this time in detail described by
cyclic accelerated cold accumulation mode, is that between cycles of accelerated cold
accumulation, a hybrid mode is used, i.e. during the cold accumulation, i.e. during
the transformation of the water 7 to form the ice 7', the same device is used to discharge
the cold, i.e. the water 7 is simultaneously obtained from the accumulated ice 7'
during the reverse transformation. The cooled refrigerant 5 with a temperature of
less than 0°C is used to supply the cold, and it is supplied to the outer environment
of the first mantle 6', while the previously used and now heated refrigerant 5 with
a temperature of more than 0°C is used to recover the cold, and it is supplied to
the inner environment of the second mantle 6". The first mantle 6' is used to build
up the ice 7' in the cold accumulator 4, and the second mantle 6" is used to melt
the ice 7'. conducting the transformation in a cyclic, daily mode, periodic intervals
of simultaneous operation are used, consisting in that the device is used in the standard
process accelerator mode of accelerated full accumulation or accelerated full discharge,
respectively. Between the successive simultaneous modes, therefore, a transitional,
or hybrid, mode is used, given above as a specific application for the device described.
Second example.
[0080] As in the first example with the following changes.
[0081] There are 500 cold accumulators 4 in the tank 1, each of which is bounded by the
first mantle 6' from the outside and the second mantle 6" from the inside, both in
the form of a spatial solid made of a thermal conductor. The distance between the
first mantles 6' of the adjacent cold accumulators 4 ranges from 2mm to 150mm, this
time 2mm. For every 1m
3 of volume of all the cold accumulators 4 cooled in the tank 1, there is between 0.01m
3 and 0.9m
3 of the refrigerant 5, this time 0.3m
3.
[0082] The circulating pump 2 is fixed outside the tank 1, and has a connection through
the circulation duct 9, via the inlet pipe 10' and the outlet pipe 10", to the tank
1 via the inlet port 11' of the tank 1 and the outlet port 11" of the tank 1, located
at opposite ends of the wall 12 of the tank 1, the same wall 12 of the tank 1, with
the inlet at the bottom above the bottom 13 of the tank 1 and the outlet at the top
of the tank 1 above the cold accumulators 4. The tank 1 is provided with a single
horizontal baffle 21, uninterruptedly attached by its edges, for at least 75% of their
full circumference, to the straight side walls 12 of the tank 1, whereby if there
were two horizontal baffles 21, they would be placed in the tank 1 alternately, with
an offset. The tank 1 is in the form of a prism with a regular polygon bottom, this
time a regular hexagon, and the coaxial mantles 6', 6" in the shape of a spatial solid
are in the form of a prism with a regular polygon bottom, also a hexagon. The spatial
solids of the mantles 6', 6" are placed in the tank 1 relative to the bottom 13 of
the tank 1 in an intermediate position, i.e. between the vertical and the horizontal
position, the deviation from the vertical being no more than 25° of angular measure,
this time 3° of angular measure to better force the spiral flow of the refrigerant
5 between the first mantles 6'. The spatial solids of the first mantles 6', in their
cross-section, have a longest diagonal no longer than 60cm, this time 6cm. The spatial
solids of the first mantles 6', in their longitudinal cross-section, have a longest
diagonal no longer than 300cm, this time precisely 300cm. The spatial solid of the
second mantle 6" in its cross-section has the longest diagonal no longer than 10cm,
but no longer than 25% of the length of the diagonal of the first mantle, this time
it has precisely 1cm. The spatial solid of the second mantle 6" in its longitudinal
cross-section, usually has the longest diagonal no longer than 95% of the length of
the longitudinal diagonal of the first mantle 6', preferably no shorter than 50%,
this time it is 300cm. The first mantles 6' on the inner side are fitted with 24 tabs,
this time flat ones. The refrigerant 5 in the tank 1 is aqueous brine. The volume
amount of micro-radicals 28 of the ice 7' is 5%.
[0083] An example of how to cool the device for storage of energy such that 500 cold accumulators
4 are cooled in one tank 1, and for every 1m
3 of volume of all cold accumulators 4 cooled in the tank 1, between 0.01m
3 and 0.9m
3 of the refrigerant 5 operating in the tank 1 outside the first mantles 6' of the
cold accumulators 4, this time precisely 0.3m
3, respectively, is used to cool them down.
[0084] This time, the temperature of the refrigerant 5 is maintained at a constant lower
than -1°C, precisely at -6°C. The volume amount of the micro-radicals 28 of the ice
7' preferably not exceeding 5% of the volume of the first mantle 6' is used, this
time precisely 5%. Between 15,000kJ and 15,000,000kJ of cooling energy is accumulated
in all cold accumulators 4 operating in the single tank 1, but this time only 8,488,800kJ.
The pressure in the tank 1 and in the cold accumulators 4 is maintained in the range
from 1atm to 6atm, this time precisely corresponding to six times atmospheric pressure.
[0085] The exemplary application of the device for storage of energy, in particular cooling
energy, with cyclic freeze-up, i.e. the generation and build-up of the ice 7', wherein
the device and/or the method shown above is used, that during the cold accumulation,
i.e. during the transformation of the water 7 into the ice 7', the same device is
used for discharging the cold, i.e. the water 7 is simultaneously obtained from the
accumulated ice 7' during the reverse transformation. The cooled refrigerant 5 with
a temperature of less than 0°C is used to supply the cold, and it is supplied to the
inner environment of the second mantle 6", while the previously used and now heated
refrigerant 5 with a temperature of more than 0°C is used to recover the cold, and
it is supplied to the outer environment of the first mantles 6'. In the hybrid mode
used here, therefore, the second mantle 6" is used to build up ice in the cold accumulator
4, and the first mantle 6' is used to melt the ice. Conducting the transformation
in a cyclic mode, periodic intervals of simultaneous operation are used, consisting
in that the device is used in the standard process accelerator mode, of accelerated
full accumulation or accelerated full discharge, respectively.
Third example.
[0086] As in the first example with the following differences
[0087] The mantles 6', 6" are completely submerged in the liquid refrigerant 5, this time
the refrigerant 5 washes over them to their full height and, in addition, the refrigerant
fills not only the chamber proper 32 of the tank 1, but the entire tank 1 including
the vestibules 30', 30", i.e. 100%. The tank 1 thus has at least one vestibule 30
by which the outer environment of the tank 1 is separated from its chamber proper
32 containing the refrigerant 5 and the cold accumulators 4 surrounded by the mantles
6', 6", the vestibule 30 being at least one manifold 30', 30". This time it has two
vestibules 30, and with two or more vestibules 30, at least one is the supply manifold
30', and at least the other is the return manifold 30". The manifolds 30', 30" are
separated from the chamber proper 32 of the tank 1 by the baffle 31, respectively
the supply manifold 30' by the first baffle 31' and the return manifold 30" by the
second baffle 31". For this reason, the mantles 6', 6" of the multiplied cold accumulators
4 are at a distance connected to the tank 1 and to each other, of which at a distance
with respect to the walls 12 of the tank 1 and with respect to the adjacent mantles
6', as well as with respect to the bottom 13 of the tank 1, because they are separated
by manifolds 30',30", the supply manifold 30' and the return manifold 30", which are
the vestibules 30 of the tank proper 32 in which the outer mantles 6' are embedded,
while the inner mantles 6" penetrate into the vestibules 30 through the baffles 31
, respectively through the first baffle 31' into the supply manifold 30' and through
the second baffle 31" into the return manifold 30". The circulation pump 2 is mounted
outside the tank 1, and has a connection via the circulation duct 9 with the inlet
pipes 10' and the outlet pipes 10", to the tank 1 and/or with the tubular inlet 33'
and the tubular outlet 33" via the inlet port 11' and the outlet port 11" of the tank
1. The inlet ports 11' and the outlet ports 11" are positioned on the opposite walls
12 of the tank 1, with the inlet at the bottom of the tank 1 and the outlet at the
top of the tank 1, but such that the tubular inlet 33' and the tubular outlet 33"
are positioned on the opposite walls 12 of the tank 1 and in other baffles 31', 31"
of the manifolds 30', 30". The method and application of the device for storage of
energy, this time, is performed so that cyclic freeze-up, i.e. the generation and
build-up of the ice 7' occurs, as well as cyclic discharge, i.e. the melting of the
ice 7' to form the water 7, separated by the application of the standard process accelerator
mode, respectively accelerated full accumulation and accelerated full discharge interchangeably
in sequence again and again consisting of simultaneous cooling of the first mantle
6' and the second mantle 6" with the refrigerant 5 and simultaneous heating of the
first mantle 6' and the second mantle 6" with the heated refrigerant 5. The hybrid
freeze-up sequence, i.e. together with the melting of the ice 7' once involves the
refrigerant 5 below 0°C flowing outside the first mantle 6' and at the same time above
0°C inside the second mantle 6", and the next time the refrigerant 5 below 0°C flows
inside the second mantle 6" and at the same time below 0°C outside the first mantle
6'. Transient, or hybrid, modes are therefore used between the successive simultaneous
modes, given above as specific applications for the device described, and the refrigerant
circulation in terms of direction and as a rule of flow depends on the settings of
the valves 29.
