Description

INSULATION SYSTEM WITH THERMAL INSULATING PARTITION

The invention relates to an insulation system for insulating an inner space relative to an outer space, in which use is made of a thermally insulating partition which flows through for a gaseous flow medium.

A number of insulation systems are known in the prior art in which use is made of a flow-through partition, such as in NL7810215.

In the unpublished application PCT / NL2018 / 05055 an insulation system is described in which an inner space is insulated by using a flow-through partition. Which insulation system includes an air flow in one direction and a heat flow in the opposite direction. Said air flow runs from the outer space to the inner space or from the inner space to the outer space through a number of flowable insulating walls. In embodiments, slats are placed between the insulating walls.

In the unpublished application NL1042647, an insulation system is described which comprises a closed gas circuit through which a gaseous medium flows which absorbs heat from the interior space or the exterior space and returns it to the interior space or exterior space via a heat exchanger. The closed gas circuit comprises a flowable insulating wall placed between the inner wall and the outer wall, which forms an inner cavity with the inner wall and an outer cavity with the outer wall. The gaseous medium flows against the direction of the heat flow. This closed insulation system has the advantage over the insulation system described in PCT / NL2018 / 05055 that possible problems such as condensation, accumulation of contamination, and mold in the insulation system can be avoided.

The invention described in this application is a further improvement over the systems described above. The object of the invention is to provide a handy and easy-to-install insulation system using a thermally insulating partition flowable through a gaseous flow medium.

The insulation system according to the invention is designed for insulating an inner space, which inner space is separated from an outer space by means of a wall

-2 comprising an inner wall and an outer wall with a cavity between them, the insulation system comprising:

a thermally insulating partition for flowable through a gaseous flow medium, and

a fan for a gaseous flow medium, the thermal insulating partition being arranged to be arranged in the cavity between the inner wall and the outer wall, so that the cavity is divided into an inner cavity and an outer cavity, the inner cavity being bounded by the inner wall and the thermally insulating partition and the outer cavity is bounded by the outer wall and the thermally insulating partition, and the thermally insulating partition separates the inner cavity from the outer cavity, and the fan is arranged to create a pressure difference between the inner cavity and the outer cavity and thus displacing a gaseous flow medium by effecting the thermally insulating separation.

According to the invention, the thermally insulating partition comprises a serpentine molded part made of a foil, for example a light-transmitting foil, which foil is folded into a serpentine mold, comprising the serpentine molded part with flanks separated by flanks, spacers being arranged around neighboring keep flanks of the serpentine molded part at a distance, and preferably make it possible to clamp the serpentine molded part while retaining the tops and valleys, the flanks being closed to the gaseous flow medium, and perforations being provided in the foil at the peaks and valleys of the serpentine molded part such that the serpentine molded part defines a plurality of parallel channels extending between the flanks of the serpentine molded part and each bounded at one end thereof by either a top or a valley of the serpentine molded part, and where the perforations at said top or that valley form inflow openings or outflow openings for the gaseous flow medium through the relevant

-3 duct under the influence of the pressure difference created by the fan between the inner cavity and the outer cavity.

The system according to the invention is able to insulate an interior space, for example a space in a house. When the insulation system according to the invention is placed, it can for instance be placed in an outer wall of the house. The inner wall, together with the thermally insulating partition, defines the inner cavity and the outer wall, together with the thermally insulating partition, the outer cavity.

The serpentine molded part of the thermally insulating partition is folded in a serpentine mold so that it forms a wave in one direction, for example the lengthwise direction, of the serpentine molded part, and in the other direction, for example, the widthwise direction, of the serpentine molded part has parallel flanks.

The spacers give a certain degree of firmness to the serpentine molded part of the thermally insulating partition. The spacers ensure that the flanks of the serpentine molded part do not collapse and touch each other undesirably, thereby blocking channels. Furthermore, spacers can ensure that the flanks of the serpentine molded part do not move too far apart when, for example, the serpentine molded part is stretched under the influence of its own weight, or when the serpentine molded part is unfolded.

The spacers can be arranged between adjacent flanks where the spacers can moreover be designed as partitions. In this case, spacers between two flanks divide the channel between those adjacent flanks into smaller channels separated from one another. The presence of baffle spacers can be beneficial to the flow through the channels.

The spacers, alternatively or in combination with spacers between the flanks, may also be attached over the group of crests and / or over the group of troughs of a serpentine molding, for example as ribbons or wires, for example vertically oriented while the flanks are horizontally oriented.

For example, a plastic spacer is attached to the foil of the serpentine molded part by means of a heat seal.

-4 In embodiments, a spacer and / or reinforcing rib is formed by thermoforming the foil.

Locally at the crests and valleys, which may not be exactly on the crest or in the valley but also in the vicinity of the crests and valleys of the serpentine molded part, perforations have been made through which the gaseous flow medium flows under the influence of the fan pressure differential generated. This flow is mainly defined by these perforations, which in practically advantageous embodiments are much smaller in cross-sectional area, also jointly, than the cross-sectional area of the connecting part of the channel defined mainly by adjacent flanks.

For example, the perforations each have a diameter between 0.2 and 1 millimeter or a corresponding cross-sectional area if the perforations are not round.

For example, the perforations with a diameter between 0.4 and 0.6 millimeters, for example 0.5 millimeters, are made.

Preferably, the distance between adjacent perforations is a multiple of the diameter of each perforation.

Preferably, one or more parallel and straight rows of perforations are arranged in the vicinity of a top or a valley, for instance arranged with a perforating machine after the foil has been unrolled from a roll.

The foil is preferably of a type which, without additional treatment, is closed or closed to the gaseous flow medium, so that the perforations form the only passage for the gaseous flow medium.

The foil is preferably a plastic foil, for instance a single-layer or multi-layer foil.

Optionally, the foil has one or more plastic foil layers and one or more metal foil layers, for example an aluminum layer, for example to obtain a heat-reflecting effect.

The foil can also be a preferably thin metal foil, possibly from a roll. A plastic film, optionally with one or more metal layers, is preferred.

-5 For example, in use, the pressure drop over the perforations is at least 10 times greater than the pressure drop over the inner cavity and the outer cavity, for example at least 15 times greater. For example, this applies to a closed gas circuit embodiment as explained herein.

The sides of the serpentine molded part are closed.

The serpentine molded part of the thermally insulating partition preferably has an even distribution of perforations over its gas-flowed surface, in particular viewed in the longitudinal direction of the flanks.

The serpentine molded part is preferably manufactured from a non-rigid, for instance thin film, for instance a film to be unrolled from a roll. For example, the foil has a thickness between 2 µm and 200 µm.

The serpentine molded part is made, for example, from a PET film. For example, if the PET film has a thickness of 5 µm and the distance between the flanks of the serpentine is, for example, 5 mm, then there are about 200 flanks per linear meter.

For example, the distance between neighboring flanks is between 3 and 10 millimeters, for example between 4 and 7 millimeters, for example 5 millimeters.

For example, the distance between the plane with the tops and the plane with the valleys of the serpentine molded part is at least 3 centimeters, for example at least 5 centimeters, for example between 7 and 12 centimeters. In a practical version, that distance is between 8 and 10 centimeters.

The ease with which heat moves through a flowable thermal wall against the direction of movement of a gaseous medium is measured with the Peclet number, Pe. Here it holds that Pe = v I p C _p / λ, where v is the medium speed perpendicular to the surface of the flowable thermal wall, I is the path length through the flowable thermal wall, p the density of the gaseous medium, C _P the heat capacity of the gaseous medium and λ is the heat conduction coefficient of the flow medium.

-6Depending on the design of the thermally insulating partition, the gaseous flow medium flows, for example, with flow rates of 0.1-4 mm / s through the thermally insulating partition.

In embodiments of the invention as described herein, it is arranged to support a Peclet number greater than 1.

If the Peclet number is greater than 1, the conductive heat through the flowable thermal wall is blocked by the flow of the gaseous medium. When the gaseous medium flows from hot to cold, a heat front occurs which blocks an opposing flux of cold. On the other hand, if the medium flow is from cold to warm, then a cold front occurs, which blocks an opposite heat flux. With a Peclet number greater than 1, virtually no heat transport takes place through the flow-through thermal wall.

If the Peclet number is greater than 1, then there is talk of a superadiabatic flow and a superadiabatic effect, the effect which ensures that virtually no heat transport takes place opposite to the flow direction of the gaseous medium.

If the gas flow has a Peclet number greater than 1 as it passes through the thermally insulating partition, a heat front or a cold front is created in the thermally insulating partition that blocks a heat flow or cold flow through the thermally insulating partition. Experiments have shown that a Peclet number of 3 is sufficient to almost completely block the heat flow or cold flow.

The superadiabatic effect can be disrupted if thermal or convective turbulence occurs in the insulation system. For this it is necessary that the flow is kept laminar. Due to the large wall area of the thermally insulating partition and the relatively small perforations in the thermally insulating partition, the flow will be mainly laminar.

Thermal turbulence can be prevented by allowing the flow medium to flow mainly horizontally through horizontal narrow gaps. The gaps can be formed by the flanks of the serpentine molded part when arranged horizontally. For an optimal effect, the flanks can be placed several millimeters apart, for example 5 mm.

In embodiments, the thermally insulating partition is arranged to be placed in the cavity such that the tops and valleys of the serpentine molding extend horizontally.

For example, the thermally insulating partition has an attachment tab at the top and bottom that extends parallel to the tops and troughs of the serpentine molded part for securing the thermally insulating partition at the top and bottom of the cavity.

In addition to preventing thermal turbulence by horizontally placing the tips and troughs of the serpentine molded part, this also ensures that the heat flow is mainly parallel to the air flow. This ensures improved insulation of the interior.

In a possible embodiment, the spacers can be folded, for example by lowering or raising an end of the serpentine mold using a folding device. For example, the spacers are arranged to be folded in half. A foldable version of the spacers, in combination with suitable foil, preferably folds the thermally insulating partition. When folded, the flanks of the serpentine molded part are close, possibly on top of each other.

If the thermally insulating separation of PET film with a thickness of 5 µm and with a distance between the flanks of the serpentine of, for example, 5 mm, then the folded package has a thickness of 3 mm per linear meter, which with a flank width of, for example, 10 cm. only forms a volume of 3 liters. The thermal insulating partition with these properties weighs 0.144 kg / m ² insulation panel at this flank width and has a specific mass of only 1.44 kg / m ³ when unfolded. In this way, the thermally insulating partition can be easily transported when folded because it is light and compact.

In possible embodiments, the spacers are arranged between the flanks of the serpentine blank and the spacers have a u-shape, either a z-shape, or an, o-shape viewed in a view parallel to a longitudinal direction of a channel formed between the flanks.

In possible embodiments, the insulation system is provided with a folding device intended for folding and unfolding the thermally insulating partition in the cavity. The folding and unfolding of the thermally insulating partition takes place by moving towards and apart from each other a first and a second end of the thermally insulating partition.

Preferably, the folding device includes a guide for guiding the at least one end during folding and unfolding.

By folding and unfolding the thermal insulating partition, the insulating effect can be switched on and off according to the wishes of the user.

In one possible embodiment, the thermally insulating partition is foldable and is suspended from cords in the insulating system that allow the thermal insulating partition to be pulled up to form a layered package or lowered to be brought from a rest position to an operating position .

In a possible embodiment, the thermally insulating partition is foldable and is suspended from cords with which the thermal partition can be pulled up to be unfolded or lowered to be folded into a layered package. When pulled up, the system is brought from a rest position to an operating position, and when lowered, the system is moved from a working position to a rest position.

In a possible embodiment, at least a portion of the thermally insulating partition is translucent to allow light transmission through the insulation system. For example, a part of the thermally insulating partition is translucent and a part of the inner wall and the outer wall form a window with the thermally insulating partition placed between them. In this embodiment, the insulation system insulates an interior space with a wall containing a window.

In a possible embodiment, the gaseous flow medium is air. This has the advantage over the use of another gas that the system is easy to install.

In a possible embodiment, the insulation system further comprises a circulation channel for connecting the inner cavity to the outer cavity such that the circulation channel with the inner cavity, the outer cavity and the intermediate thermal insulating partition forms a closed gas circuit, which is filled with a gaseous flow medium. Furthermore, the insulation system comprises a heat exchanger adapted to exchange heat between the gaseous flow medium in the closed gas circuit on the one hand and a separate heat exchange medium flow therefrom on the other hand.

In this embodiment, the fan is arranged to effect circulation through the closed gas circuit of the gaseous flow medium.

An advantage of these embodiments is that the heat, or cold, that enters the system from the inner space is recovered by a heat exchanger and is therefore not lost. This heat or cold can in turn be usefully used for, for example, heating or cooling the interior.

In closed system embodiments, the gaseous flow medium may consist of a number of different gases. The gaseous flow medium can be, for example, air, argon, krypton, or carbon dioxide. The gas chosen to serve as a gaseous flow medium, due to the size of the Peclet number, influences the degree of insulation by the insulation system.

The choice of which gaseous flow medium is chosen can be made on the basis of both user requirements and economic arguments.

Depending on the choice of the gaseous flow medium, the closed gas circuit must be sufficiently gastight.

The insulation system according to the invention, in suitable embodiments, can function in a number of different ways depending on the temperature in the inner space relative to the outer space, whether the system comprises an open or a closed gas circuit, and the direction of circulation of the gaseous flow medium.

In a first possibility for a system with an open gas circuit, i.e. a system without a closed gas circuit, the inner space is desirably warmer than the outer space and ventilation air flows through the thermally insulating wall from the inner space to the outer space. In this case, the ventilation air will cool as it passes through the thermally insulating

-10 secretion flows. If the Peclet number is greater than 1, a cold front will occur in the thermally insulating partition and virtually no heat will be lost by the ventilation air.

In a second option for an open gas circuit system, the interior is desirably warmer than the exterior and ventilation air flows through the thermally insulating wall from the exterior to the interior. In this case, the ventilation air will heat up as it flows through the thermally insulating partition. If the Peclet number is greater than 1, hardly any cold will flow into the interior via the ventilation air.

In a third option for an open gas circuit system, the interior space is desirably colder than the exterior space and ventilation air flows through the thermally insulating wall from the interior space to the exterior space. In this case, the ventilation air will heat up as it flows through the thermally insulating partition. If the Peclet number is greater than 1, hardly any cold will be lost due to the ventilation air.

In a fourth option for an open gas circuit system, the interior is desirably colder than the exterior and ventilation air flows through the thermally insulating wall from the exterior to the interior. In this case, the ventilation air will cool as it flows through the thermally insulating partition. If the Peclet number is greater than 1, virtually no heat will enter the interior through the ventilation air.

In a first possibility for a system with a closed gas circuit, the inner space is desirably warmer than the outer space and the gaseous flow medium flows through the thermally insulating wall from the inner cavity to the outer cavity. In this case, the gaseous flow medium will cool as it flows through the thermally insulating partition. Then, the cooled gaseous flow medium will flow to the heat exchanger where the gaseous flow medium extracts heat from a warm heat exchange medium. The heated gaseous flow medium then flows back to the inner cavity. In this way, part of the heat is recovered and can be used for, for example, heating the interior.

In a second possibility for a closed-loop gas circuit system, the inner space is desirably warmer than the outer space and the gaseous flow medium flows through the thermally insulating wall from the outer cavity to the inner cavity. In this case, the gaseous flow medium will heat up as it passes through the thermally insulating partition

-11 flows. Then, the heated gaseous flow medium will flow to the heat exchanger where the gaseous flow medium extracts cold from a cold heat exchange medium. The cooled gaseous flow medium then flows back to the outer cavity. In this way, some of the cold that would have entered can be used for other purposes.

In a third possibility for a closed gas circuit system, the inner space is desirably colder than the outer space and the gaseous flow medium flows through the thermally insulating wall from the outer cavity to the inner cavity. In this case, the gaseous flow medium will cool as it flows through the thermally insulating partition. Then, the cooled gaseous flow medium will flow to the heat exchanger where the gaseous flow medium extracts heat from a warm heat exchange medium. The heated gaseous flow medium then flows back to the outer cavity. In this way, part of the heat that would have penetrated through the ventilation air is retained.

In a fourth possibility for a closed-circuit gas system, the inner space is desirably colder than the outer space, and the gaseous flow medium flows through the thermally insulating wall from the inner cavity to the outer cavity. In this case, the gaseous flow medium will heat up as it flows through the thermally insulating partition. Then, the heated gaseous flow medium will flow to the heat exchanger where the gaseous flow medium extracts cold from a cold heat exchange medium. The cooled gaseous flow medium then flows back to the inner cavity. In this way, part of the cold is recovered and can be used, for example, to cool the interior.

In the closed system, the heat losses depend on the rate at which the gaseous flow medium flows through the thermally insulating partition and past the heat exchanger. At a high speed due to the thermally insulating partition, a high Peclet number is achieved, however the heat exchanger must exchange more heat that can be used usefully. If the speed is too high, this is no longer the case and an unnecessarily large heat exchanger with unnecessary blind power and additional blind losses is required. The optimal Peclet number thus depends on the heat or the ventilation flow required to heat or ventilate the interior, for example. If a lot of ventilation or heat is required, the Peclet number is high and the conduction losses are low and vice versa. The velocity of the gaseous flow medium,

The arrangement of the fan adapted to effect circulation of the gaseous flow medium through the closed gas circuit must be such that the net heat loss is minimal. In combination with a suitable heat exchanger, the efficiency can be further increased.

In a possible embodiment of the closed system, the gaseous flow medium is carbon dioxide gas. Carbon dioxide gas provides better insulation than if the system was filled with air and is relatively inexpensive.

In a possible embodiment, a heat exchanger is arranged for exchanging heat between the gaseous flow medium and a separate flow of ventilation air to or from the relevant interior space. In an example of an embodiment, the heat exchanger extracts heat from the gaseous flow medium and releases it to cold ventilation air coming from outside. In this case, the interior space will be warmer than the exterior space and unnecessary cold will not enter the interior space via the ventilation air.

In a possible embodiment, a heat exchanger is arranged for exchanging heat between the gaseous flow medium and a heating medium for the relevant interior space. In an example of an embodiment, the heat exchanger extracts heat from the gaseous flow medium and delivers it to water intended for the heating installation in the interior. In this case, the interior space will be warmer than the exterior space and less energy will be required for the heating installation in the interior space.

In a possible embodiment, the insulation system is further provided with a control system for controlling, preferably automatic control, the fan and / or the folding device, the control system preferably comprising one or more sensors. The control system may, for example, be provided with a pressure sensor for measuring the pressure in the inner cavity or the outer cavity or a temperature sensor for measuring the temperature in the inner space, the outer space, the inner cavity, or the outer cavity. The one or more sensors provide information on the basis of which the fan and / or the folding device can be controlled.

Preferably, a laminar flow takes place in the insulation system, the control system can ensure that the flow remains laminar by controlling the fan.

-13 The Peclet number can be influenced by controlling the fan. The Peclet number determines the degree of insulation of the system and it may be preferable to adjust the Peclet number in relation to a small temperature difference in case of a large temperature difference between the interior and the outdoor space in order to increase the insulation value of the system.

In embodiments, the insulation system comprises positioning means arranged to be placed in the inner cavity, between the inner wall and the thermal partition, and / or in the outer cavity, between the outer wall and the thermal partition. The positioning means position the thermal barrier with respect to the inner wall and the outer wall, respectively, without blocking the flow of the channels. The positioning means are, for example, in the form of a perforated plate, ribs or a corrugated sheet, the ribs and the corrugated sheet being arranged such that the ribs and the waves respectively extend in a direction perpendicular to the channels of the thermally insulating partition.

Due to the flow of the gaseous flow medium through the insulation system, the thermally insulating partition can be pushed from its ideal position. The positioning means ensure that this does not happen while at the same time not blocking the flow.

In embodiments, the inner wall has a significant insulating effect, for example, the inner wall determines more than 10% of the insulation value of the insulation system. Due to the insulating effect of the inner wall, the temperature in the inner cavity can be lower than if the inner wall has a less insulating effect. As a result, the temperature drop across the thermal insulating wall is lower and more flowing medium must be circulated to maintain the heat capacity and the insulation system can function at a higher Peclet number, i.e. at a higher flow rate of the gaseous flow medium, resulting in better insulation of the insulation panel. It is possible that optimal insulation is achieved by a combination of an insulating inner wall and an insulation system according to the invention. For example, a combined system can be advantageous with a large temperature difference between the interior and the exterior.

The invention also relates to a thermal insulating partition claim 17, which thermal insulating partition is flowable for a gaseous

-14 flow-through medium, for providing an insulation system according to one or more of claims 1-16.

The invention also relates to an insulation panel according to claim 18.

The insulation panel can be manufactured in its entirety in a central location and transported to interior space to be insulated. An advantage of this embodiment is that, for example, walls with the thermally insulating partition can be manufactured quickly and efficiently.

In embodiments, the insulation panel is provided with a connection opening which communicates with the inner cavity and a connection opening which communicates with the outer cavity. The connection openings can be used for introducing and / or outputting a gaseous flow medium into and / or from the inner cavity and the outer cavity, respectively.

The connection openings allow the insulation panel to be connected to, for example, an existing ventilation system.

In embodiments, the connection openings communicate with the inner cavity or outer cavity through a row of multiple discrete openings or a single elongated opening extending along the majority of the respective side of the inner cavity or outer cavity.

By designing the connection openings in this way, a good distribution of the supply and / or output of the gaseous flow medium will take place.

In embodiments, the connection opening, which communicates with the inner cavity, and the connection opening, which communicates with the outer cavity, communicates with the respective cavity in opposite sides of the panel. For example, on the top and bottom of the panel and / or the left and right side of the panel, respectively.

By placing the connection openings at opposite locations, the gaseous flow medium will spread through the panel and improve the insulation value.

In embodiments, the insulation panel is provided with a folding device for folding and unfolding the thermal insulating partition in the cavity by moving towards and apart from each other a first end and a second end of the foil. The folding device preferably includes a guide for guiding at least one end of the thermally insulating partition during folding and unfolding.

The folding and unfolding of the thermally insulating partition has the advantage that the insulating effect of the system can be switched on and off.

In embodiments, the insulation panel comprises positioning means placed in the inner cavity, between the inner wall and the thermally insulating partition, and / or in the outer cavity, between the outer wall and the thermally insulating partition. The positioning means serve to position the thermally insulating partition with respect to the inner wall and the outer wall, respectively, without blocking the flow-through of the channels.

The positioning means are, for example, in the form of a perforated plate, ribs or a corrugated sheet, the ribs and corrugated sheet being arranged such that the ribs and the waves respectively extend in a direction perpendicular to the channels of the thermally insulating partition.

In embodiments, the positioning means are connected to the inner wall and / or the outer wall and also function as guides for guiding at least one end of the thermally insulating partition during folding and unfolding.

The folding and unfolding will be better by conducting the thermally insulating partition.

In embodiments, the positioning means are connected to the tops and / or the valleys of the thermally insulating partition. The positioning means thus form a sandwich construction with the thermally insulating partition.

In embodiments, the positioning means are made of corrugated sheets arranged so that the waves extend in a direction perpendicular to the channels of the thermally insulating barrier. The waves of the corrugated sheet are connected near the crests to the crests and troughs of the thermally insulating barrier.

In embodiments, the corrugated sheet waves near their peaks are provided with perforations which overlap with the perforations provided in the peaks or troughs of the thermally insulating barrier.

In embodiments, a corrugated sheet is provided in the inner cavity and a corrugated sheet is provided in the outer cavity, in which channels formed by the corrugated sheet are alternately connected to a first connection opening and a second connection opening, such that the corrugated sheets in combination with the thermally insulating partition have a first gas circuit and form a second gas circuit, each having channels in the inner cavity and channels in the outer cavity, the channels of the first gas circuit being alternated with channels of the second circuit.

In this embodiment, air in the first gas circuit can flow from the inner space to the outer space and air in the second gas circuit can flow from the outer space to the inner space. For example, if the inner space is warmer than the outer space, in this embodiment the ventilation air in the first gas circuit can flow from warm to cold and the ventilation air in the second gas circuit can flow from cold to warm. By allowing heat transfer between the two gas circuits, the insulation panel can be equipped with a heat exchange effect.

In embodiments, the insulation panel is provided with a fan, which is adapted to effect a pressure difference between the inner cavity and the outer cavity, and thus a displacement of a gaseous flow medium through the thermally insulating partition.

According to another aspect of the invention, the insulating panel chamber according to one or more of claims 18-29 is a gas-tight chamber, and the panel further comprises:

- a circulation channel, which circulation channel is coupled to the connection openings such that the circulation channel connects the inner cavity to the outer cavity and the circulation passage with the inner cavity, the outer cavity, and the intermediate thermal insulating partition forms a closed gas circuit, which is filled with a gaseous flow medium; and

- a heat exchanger, which is arranged, when the panel is arranged between an inner space and an outer space, to effect exchange of heat between

-17 the gaseous flow medium on the one hand and a separate flow of heat exchange medium on the other hand,

This embodiment of the insulation panel has the advantages of the closed insulation system and of the insulation panel. It is a closed system that can be manufactured in a central location.

In an embodiment of the insulation panel, a part of the circumferential wall delimits a part of the circulation passage. In this embodiment, the part of the circumferential wall is designed as a heat exchanger.

In one embodiment, the panel is provided with a top edge and a bottom edge, which top edge and bottom edge are connected to each other by means of two side edges. The thermally insulating partition is arranged between the inner wall and the outer wall such that the tops and valleys of the serpentine molded part extend parallel to an upper edge and a lower edge of the panel. When the panel is installed, the thermal insulating partition extends in a substantially vertical direction, and the tops and valleys of the serpentine blank extend parallel to the horizontal.

In an embodiment of the insulation panel with the top edge and bottom edge, the panel is provided with pads that extend on the inside of the room and along the sides of the panel. The pads engage the edges of the insulating thermal partition to provide a substantially leak-tight seal between a side of the chamber and a side of the thermally insulating partition.

In one embodiment of the cushion insulation panel, the cushions are inflatable cushions. In the inflated state, the pads form a leak-tight seal with the thermally insulating partition, and in the non-inflated state, the pads allow displacement of the thermally insulating partition along the pads. Preferably, the cushions are inflated by the fan, which is also adapted to create a pressure difference between the inner cavity and the outer cavity.

The invention also relates to a building with at least one interior space, characterized in that the building is provided with an insulation system according to any one of claims 1-15, and / or a thermally insulating partition according to claim 17, and / or with a or more insulation panels according to one or more of claims 18-34.

-18 For example, the building is a horticultural greenhouse, in which the insulation system is installed in the roof and / or in the side wall of the greenhouse. The walls and the insulating partition for daylight are advantageously transparent, so that daylight can enter the greenhouse. However, it may also be the case that the insulating partition is foldable and a folding device is provided. In that case, the insulating partition does not have to be permeable to daylight. In fact, a conscious choice can be made not to design the collapsible insulating partition in a transparent manner, for example with a metal layer in a plastic film. In the evening and at night, for example, undesired light radiation from a greenhouse that is then lit with artificial light can be prevented. In addition, it is possible to opt to realize the insulating effect for the greenhouse only in the evening and / or at night. The invention also relates to a method for growing a crop in a greenhouse provided with an isolation system as explained herein, in particular a greenhouse provided with heating means for maintaining a heated climate in the greenhouse. It will be clear that the same idea can also be used for other buildings.

The invention also relates to a method for insulating an inner space relative to an outer space, characterized in that the method comprises applying:

an insulation system according to one or more of claims 1 to 16, and / or

- a thermally insulating partition according to claim 17, and / or

- installing an insulation panel according to one or more of claims 18-34.

The invention also relates to a method for manufacturing a thermally insulating partition, characterized in that the method comprises:

- providing rows of perforations in the foil;

- applying spacers, between the rows of perforations and on both sides of the foil, by attaching the spacers with one end to the foil:

alternately folding the film in half and attaching an opposite end of the spacers to the film to form and retain the serpentine molded part, respectively.

The invention also relates to a method for manufacturing a thermally insulating partition, characterized in that the method comprises:

thermoforming a foil to form spacers and / or reinforcing ribs from the foil;

- providing rows of perforations in the foil, for example in the foil formed by thermoforming, for instance between the spacers and / or reinforcing ribs previously formed by thermoforming;

- alternately folding the foil in half,

- attaching the spacers.

Attaching the spacers to a flank of the serpentine molded part can be effected, for example, by means of a heat-seal, if the spacer is suitably designed, for instance also from foil, for example by thermoforming formed from the same foil

This method of manufacturing the thermally insulating partition has the advantage that the thermally insulating partition is manufactured from a foil and the method is simple to automate.

In a second embodiment of the present invention, the serpentine mold is maintained by ribbon spacers which are welded or glued to the tips and troughs of the serpentine molded part. The flanks are reinforced with thermoforming reinforcing ribs, which are nested when nested when the thermally insulating partition is folded together. In this state, the superadiabatic effect is not present.

The reinforcing ribs are, for example, ribs on the flanks of the serpentine molded part. This has the advantage that the flanks warp less easily, so that the channels remain better defined.

This method of manufacturing the thermally insulating partition has the advantage that the thermally insulating partition can be folded together more easily.

Figure 1 shows a first view of a first embodiment of an insulation system according to the invention.

The insulation system (1) is placed between an inner space (2) and an outer space (3), which are bounded by a respective inner wall (5) and an outer wall (6). The insulation system comprises a thermally insulating partition (8) for a gaseous medium flow-through, which is placed between the inner wall (5) and the outer wall (6).

The thermally insulating partition (8) is placed between the inner wall (5) and the outer wall (6) so that there is an inner cavity (10), between the inner wall (5) and the

-21 thermal insulating partition (8), and an outer cavity (11), between the thermally insulating partition (8) and the outer wall (6), is formed.

The insulation system (1) further comprises a fan (9) adapted to create a pressure difference between the inner cavity (10) and the outer cavity (11). As a result, a flow of the gaseous flow medium through the thermally insulating separation is effected.

The thermally insulating partition (8) is made of a thin foil and is folded in a serpentine form. The serpentine molded part includes flanks (12), crests (13), and valleys (14).

Spacers (15) are arranged between the flanks (12), for example made of the same material as the thermally insulating partition (8). The spacers (15) are placed in such a way that they keep the flanks (12) of the thermally insulating partition (8) separate. Preferably the spacers (15) also ensure that the flanks (12) continue to run sufficiently parallel when the serpentine molded part is clamped.

The serpentine mold defines a number of channels (17) bounded by the flanks (12) and the spacers (15) and bounded on one side by a crest (13) or a valley (14) of the serpentine mold. A number of perforations (16) are provided in the tops (13) and valleys (14) of the serpentine molded part so that the gaseous flow medium flows through the channels from the inner cavity (10) to the outer cavity (11) or from the outer cavity (11) to the inner cavity (10) can flow. When the channel (17) flows through, the perforations (16) form inflow openings or outflow openings for the respective channels (17).

The fan (9), which creates a pressure difference in the gaseous flow medium between the inner cavity (10) and the outer cavity (11), and the thermally insulating partition (8) are arranged to have a Peclet number greater than 1 in the insulation system (1 ). In particular, the perforations are arranged in the flow-through surface such that the flow of the gaseous flow-through medium is sufficiently laminar and rapid for a superadiabatic effect to occur.

Figure 1 is a side view of an insulation system (1) according to the invention in which the tops (13) and troughs (14) of the thermally insulating partition (8) extend parallel to a horizontal. For example, the thermally insulating partition (8)

-22 attached to a mounting tab (not shown) from which the thermal insulating partition (8) is suspended.

The spacers (15) disposed between the flanks (12) of the serpentine molded part are seen in side view in Figure 1. For example, from a view parallel to the flow of the gaseous flow medium through the channels (17), the spacers (17) have an o-shape or a u-shape.

The insulation system (1) in figure 1 is provided with guide (18) which, if possible fold up the thermally insulating partition (8), conduct the thermally insulating partition. The guides (18) in this embodiment are formed from the inner wall (5) and the outer wall (6).

In this embodiment, the guide (18) serves as a positioning means (22). The pressure difference between the inner cavity (10) and the outer cavity (11) puts pressure on the thermally insulating partition (8) to move out of its intended position. The positioning means (22) are arranged to keep the thermally insulating partition (8) separate from the inner wall (5) and the outer wall (6).

In embodiments, the inner wall (5) has a significant insulating effect, for example, the inner wall determines more than 10% of the insulation value of the insulation system (1).

In Figure 2, the embodiment of Figure 1 is shown in a cross section from a top view.

The inner space (2) is separated from the outer space (3) by the insulation system (1). The insulation system (1) comprises the thermally insulating partition (8) placed between the inner wall (5) and the outer wall (6).

The inner wall (5) together with the thermally insulating partition (8) delimits the inner cavity (10) and the outer wall together with the thermally insulating partition (8) delimits the outer cavity (11). The thermally insulating partition (8) includes crests (13), troughs (14), and flanks (12).

Spacers (15) are placed in the thermally insulating partition (8) to prevent the flanks (12) of the serpentine molding from coming into contact with each other.

In the embodiment shown in Figure 2, the spacers (15) are formed in an O shape.

Perforations (16) are provided in the tops (13) and valleys (14) of the serpentine blank. The perforations together with the flanks (12), the spacers (15), the tops (13), and the valleys (14) form channels (17) through which the gaseous flow medium flows through the thermally insulating partition (8).

Positioning means (22) are attached to the inner wall (5) and the outer wall (6) to prevent the thermally insulating partition (8) from coming into contact with the inner wall (5) and / or the outer wall (6).

In the embodiment given in figure 1 and figure 2, the gaseous flow medium flows from the inner space (2) through the supply (23) through the inner cavity (10) through the thermally insulating partition (8) and through the outer cavity (11) into the outer space (3).

If, for example, the inner space (2) is desired to be warmer than the outer space (3), a heat flow will occur which flows from the inner space (2) to the outer space (3). This is the third possibility as discussed in the open system description introduction.

The gaseous flow medium will heat up as it flows through the channels (17) of the thermally insulating partition (8). Because the heat flow is opposite, the heat flow will experience some resistance from the flow of the gaseous flow medium and, with a Peclet number greater than 1, there will be practically no cold from the interior (2) through the insulation system (1) to the exterior ( 3) flows.

Figure 3 shows a cross-sectional side view of an insulation panel (21) with a closed gas circuit and positioning means (22) according to the invention.

The embodiment as given in figure 3 comprises an insulation panel (21) placed between an inner space (2) and an outer space (3). The insulation panel comprises an inner wall (5) and an outer wall (6) between which a thermally insulating partition (8) is placed. The thermally insulating partition (8) defines an inner cavity (10) together with the inner wall (5) and an outer cavity (11) together with the outer wall (6).

-24The thermally insulating partition (8) is in a serpentine form with flanks (12), tops (13), and valleys (14). Spacers (15) are placed between the flanks (12) which prevent the flanks (12) from coming into contact with each other.

Perforations (16) are provided in the tops (13) and valleys (14) of the serpentine molded part. The perforations (16), spacers (15), flanks (12), crests (13), and valleys (14) of the serpentine mold form channels (17) through which a gaseous flow medium can flow.

In this embodiment, the gaseous medium is, for example, carbon dioxide gas.

The insulation system (1) further comprises a fan (9) adapted to create a pressure difference between the inner cavity (10) and the outer cavity (11), thus effecting a displacement of the gaseous flow medium by the thermally insulating separation ( 8).

The insulation system (1) further comprises a circulation channel (19) connecting the inner cavity (10) and the outer cavity (11) and together with the inner cavity (10), the outer cavity (11), and the intermediate thermal insulating partition (8) closed gas circuit. A gaseous flow medium flows through the closed gas circuit.

A heat exchange medium flows through a heat exchanger (20) and exchanges heat between the gaseous flow medium and the heat exchange medium.

Corrugated sheets (22) are arranged in the insulation panel (21) for positioning the thermally insulating partition (8) relative to the inner wall (5) and the outer wall (6), respectively. The waves of the corrugated sheets (22) extend perpendicular to the channels (17) of the thermally insulating partition (8).

Figure 4 shows a cross-sectional plan view of the insulation panel with a closed gas circuit and positioning means of Figure 3.

The insulation panel (21) is placed between an inner space (2) and an outer space (3) and comprises an inner wall (5) and an outer wall (6). A thermally insulating partition (8) is placed between the inner wall (5) and the outer wall (6), which together with the inner wall (5) forms an inner cavity (10) and together with the outer wall (6) forms an outer cavity (11).

The serpentine molded part of the thermally insulating partition (8) comprises tops (13) and valleys (14), perforations (16) being made in the foil near those tops and valleys. The thermally insulating partition (8) forms a serpentine comprising flanks (12) separated from each other by spacers (15).

The spacers (15) together with the flanks (12), crests (13), valleys (14), and perforations (16) form channels (17) through which a gaseous flow medium, for example air or possibly carbon dioxide, flows.

Corrugated sheets (22) are used in the inner cavity (10) and outer cavity (11), which serve as positioning means (22) for the serpentine mold part of the thermally insulating partition (8). The waves of this positioning corrugated sheet are arranged such that the waves thereof extend perpendicular to the crests (13) and valleys (14) of the serpentine molded part.

Near their top, the waves of the positioning corrugated plates (22) are connected to the tops (13) or the valleys (14) of the thermally insulating partition (8). Perforations (16) which overlap with the perforations (16) of the thermally insulating partition (8) are provided in the tops of the corrugated sheets.

In the embodiment of Figure 3 and Figure 4, for example, it is desirably warmer in the inner space (2) than in the outer space (3). This is the first option for a closed gas circuit system as described in the description introduction.

The gaseous flow medium flows through the thermally insulating wall (8) from the inner cavity (10) to the outer cavity (11) and through the circulation channel (19), driven by the fan (9), back to the inner cavity (10).

The gaseous flow medium will cool as it flows through the thermally insulating partition (8). When the gaseous flow medium subsequently flows through the circulation channel (19), it will extract heat in the heat exchanger (20) from the warm heat exchange medium flowing from the inner space (2) to the outer space (3). The cooled gaseous flow medium then returns to the inner cavity (10).

-26 Fig. 5 shows a cross-sectional side view of an insulation system with a first gas circuit and a second gas circuit.

The insulation system 1 is placed between an inner space 2 and an outer space 3, which are bounded by a respective inner wall 5 and a respective outer wall 6. The insulation system comprises a thermal insulating partition 8 which flows through for a gaseous medium and which flows between the inner wall 5 and the outer wall 6 is positioned and is bounded by two positioning means 22 which are designed as corrugated sheets. A first corrugated sheet 22a is placed between the thermally insulating partition 8 and the inner wall 5 and a second corrugated sheet 22b is placed between the thermally insulating partition 8 and the outer wall 6.

The corrugated sheets 22 are perpendicular to the serpentine mold part of the thermally insulating partition 8, so that in Fig. 5 only a top and a valley of the corrugated sheets 22 are drawn.

The thermally insulating partition 8 is made of a foil and is folded in a serpentine form. The serpentine molded part comprises flanks 12, tops 13, and valleys 14. Spacers 15 are arranged between the flanks 12, which are arranged to keep the flanks 12 separate from the thermally insulating partition 8.

The tips 13 of the serpentine molded part of the thermally insulating partition (8) are attached to the tops of the first corrugated sheet 22a and the valleys 14 of the serpentine molded part of the thermally insulating partition 8 are attached to the valleys of the second corrugated sheet 22b. Perforations are provided in the tops (13) and valleys 14 of the serpentine mold part of the thermally insulating partition 8 and of the corrugated plates 22 so that the gaseous flow medium can flow through the corrugated plates 22 and the thermally insulating partition 8 via the perforations.

The thermally insulating partition 8 together with the inner wall 5 forms an inner cavity 10 and together with the outer wall 6 an outer cavity 11. The first corrugated sheet 22a splits the inner cavity 10 into two parts, a first inner cavity 10a and a second inner cavity 10b which are separated from each other through the first corrugated sheet 22a. The second corrugated sheet 22b splits the outer cavity 11 into two parts, a first outer cavity 11a and a second outer cavity 11b which are separated from each other by the second corrugated sheet 22b.

-27Fig. 6 shows a cross-sectional plan view of the insulation system with a first gas circuit and a second gas circuit of FIG. 5. The corrugated plates 22 are shown in a view perpendicular to the wave. The first corrugated sheet 22a divides the inner cavity 10 into a first inner cavity 10a and a second inner cavity 10b. The first inner cavity is located between the inner wall 5 and the first corrugated sheet 22a and the second inner cavity is located between the first corrugated sheet 22a and the thermally insulating partition 8.

The second corrugated sheet 22b divides the outer cavity 11 into a first outer cavity (11a) and a second outer cavity 11b. The first outer cavity 11a is located between the thermally insulating partition 8 and the second corrugated sheet 22b and the second outer cavity 11b is located between the second corrugated sheet 22b and the outer wall 6.

In this embodiment, two gas circuits are formed. In a first gas circuit, air flows from the outer space 3 via the first outer cavity 11a through the thermally insulating partition 8 and via the first inner cavity 10a to the inner space 2. In a second gas circuit, air flows from the inner space 2 via the second inner cavity 10b insulating partition 8 and via the first pipe cavity 11a to the outside space 3.

If the inner space 2 is desirably warmer than the outer space 3, air in the first gas circuit will flow from cold to warm and as it flows through the insulation system 1 it will absorb heat from air flowing from the inner space 2 to the outer space 3 in the second gas circuit. In this way, the insulation system 1 has a heat exchange effect.

Fig. 7 shows a foil with spacers formed by thermoforming therein. The spacers 15 are formed from a foil 8 using a thermoforming process. As a rule, the foil is thereby heated and then deformed over or in a mold and then cooled.

In this embodiment, the spacers have a triangular shape in side view. The spacers are arranged in rows on the foil and rows alternately protrude above and below the foil. Perforations 16 are arranged in rows between the spacers 15.

Fig. 8 shows a folded film in which the thermoformed film is folded into the serpentine molded part of the thermally insulating partition 8. The spacers 15 are connected to the upper flanks 12 of the serpentine molded part by means of fusion welding points 24. The spacers 15 are with a slight deviation

-28 welded together. This has the advantage that the spacers 15 are not welded together but that they are attached to the flanks 12 of the serpentine molded part.

Fig. 9 shows a side view of the folded foil of fig. 8 and fig. 10 shows a top view of the folded foil of fig. 8. The spacers 15 are formed with two pairs of welding points 24 per spacer 15. This ensures that the spacers 15 simply welded together with a small deviation.

Fig. 11 shows a front view of a second embodiment of a serpentine molded part with reinforcing ribs 25 formed by thermoforming. The reinforcing ribs 25 are formed from a foil 8 using a deep drawing process. Ribbon-shaped spacers 15 are used in this embodiment, which are connected to the tops and valleys of the serpentines with welding or glue. Perforations 16 are arranged in rows between the reinforcing ribs 25.

Fig. 12 shows a side view of the folded foil of fig. 11 and fig. 13 shows a top view of the folded foil of fig. 11. The ribbon-shaped spacers 15 run perpendicular to the flanks, preferably vertically, and are fixed by these with the tips and joining the serpentine molded part by welding, glue, or other means.

Fig. 14 shows a folded film of the second embodiment in which the reinforcing ribs 25 are nested together. In this state, the superadiabatic effect is not present and when used for window insulation, the view is undisturbed when the insulation system is in this folded state.
