    CONTROL OF THE INDOOR CLIMATE IN AN INDOOR AREA WITH AN INSULATION COMPOSITION LOCATED UNDER THE FLOOR
    The invention relates to controlling an indoor climate of an interior space, which interior space is partially bounded by a floor, wherein an underfloor space, for example a crawl space, is present under the floor.
    The invention has for its object to propose a climate control and associated means which provide one or more improvements with respect to known underfloor insulation solutions.
    For example, it is intended to provide a climate control that achieves one or more of the following objectives: improved energy efficiency, employability for multiple climate technology purposes, easy to install, low-cost to manufacture, easy to store and transport, easy to install, no substantial restriction to later access to the crawl space.
    The invention provides a method according to claim 1 for controlling an indoor climate of an indoor space. Here, the interior space is partially bounded by a floor, with a floor space underneath, such as a crawl space or a (non-heated) basement.
    The method uses a flow-through insulation assembly that is arranged under the floor of the interior space and in the subfloor space. For example, the assembly with its lower wall is laid on the bottom in the crawl space.
    The insulation assembly has a gas-tight chamber with an upper wall, a lower wall, and a circumference, for example with a circumferential wall. The top wall is at a distance below or against the floor of the interior. In a practical embodiment, several insulation assemblies are arranged under a floor, for example side-by-side, or for instance between floor beams, such that the underside of the floor is almost completely covered with insulation assemblies.
    In an insulating assembly, the top wall and the bottom wall, and the optional circumferential wall, are each substantially formed by an airtight foil material, for example of suitable plastic foil.
    Furthermore, a perforated upper foil and a perforated lower foil are arranged in the gas-tight chamber.
    The top wall, the bottom wall, the perforated top film, and the perforated bottom film are airtightly connected at the periphery of the gas-tight chamber, so that between the
    - perforated upper foil and the upper wall an upper cavity of the insulating assembly is limited, an under-cavity of the insulating assembly is bounded between the perforated lower foil and the lower wall, and a space which is permeable for gas to flow through between the perforated upper foil and the perforated lower foil.
    The insulation assembly has an upper opening that connects to the upper cavity, and a lower opening that connects to the lower cavity.
    The method uses a fan system with at least one fan.
    For controlling the indoor climate of the indoor space, that fan system is operated with the one or more fans to supply a gas, for example air, to the gas-tight chamber of the insulation assembly.
    The gas, for example air, is supplied via one of the bottom opening and the top opening. The supplied gas leaves the gas-tight chamber via the other of the bottom opening and the top opening. Depending on which of the bottom opening and the top opening the gas is supplied to, the gas flows through the insulation assembly either from below to above or from above to below.
    If the gas is supplied through the bottom opening through the fan system, the gas enters the associated under-cavity and then passes through the perforated under-foil associated with that cavity. The gas then enters the gas-flowable space between the lower film and the upper film, and flows upwardly through that space, and then leaves that space through the perforated upper film. The gas then flows into the upper cavity and leaves that upper cavity and the gas-tight chamber through the upper opening.
    In one embodiment, the fan system is only capable of realizing this flow from the bottom up.
    It is also conceivable that the fan system is arranged and operated to realize a gas flow from top to bottom. The gas is supplied via the top opening through the fan system and the gas enters the corresponding upper cavity. Then the gas passes through the perforated upper foil associated with that cavity. The gas then enters the gas-flowable space between the lower film and the upper film, and flows downwardly through that space, and then leaves that space through the perforated bottom film. The gas then flows into the under-cavity and leaves that under-cavity and the gas-tight chamber through the bottom opening.
    It is also conceivable, even advantageous, if the fan system is arranged and operated such that a flow from below to above or a flow from above to below can be realized through the insulation assembly.
    On the basis of examples, it will be further explained which flow direction is favorable for which purpose of the control of the indoor climate.
    The perforated upper foil and perforated lower foil have small flow openings or perforations, which are preferably present over the majority of the surface of the upper foil and the lower foil.
    For example, the upper foil and the lower foil are perforated over substantially their entire surface, for example evenly over the entire surface.
    For example, the perforated upper film and / or the perforated lower film are provided with a heat radiation reflecting layer, for example a metal layer, for example provided with a metal foil, for example plasticized aluminum. A blockage of heat radiation is hereby achieved.
    For example, the perforations each have a cross-section between 0.04 mm and 1 mm, preferably between 0.1 and 0.5 mm. The perforations can be present evenly over the entire surface or in groups.
    For example, at least 10,000 perforations per m2 are present in the perforated bottom film and / or perforated top film.
    For example, the perforated upper film and / or the perforated lower film are made of a vapor-permeable film, which has perforations that allow water vapor to pass through. For example with perforations with a diameter between 0.04 mm and 0.2 mm, for example between 0.05 and 01 mm. Such vapor-permeable film is used in the construction industry at large schools for other purposes. For example, the vapor-permeable film has an aluminum layer or the film is metallized, for example with aluminum.
    For example, the perforations are so small that a water column of 5 centimeters does not penetrate the perforations.
    For example, a vapor-permeable aluminum foil is used for the perforated upper foil and / or the perforated lower foil, for example with perforations of 0.2 mm diameter and with 20 perforations per cm 2.
    The flow of the gas experiences in each case a pressure drop during the passages through the perforated films. For a good flow distribution over the horizontal cross-sectional area of the flow-through space, it is preferable that the pressure drop across the perforated
    -4 foils and the intervening space is at least 15 times greater than the pressure drop across each of the cavities. This pressure drop can be realized by appropriately carrying out the selection of the pores in the perforated films and / or the size of the cavities.
    The method makes it possible for the gas that flows through the space between the perforated bottom film and top film, i.e. from bottom to top or vice versa, to flow faster than a speed of diffusion of the gas. Depending on the situation, heat or cold, which then flows in parallel with the gas, cannot flow against the gas flow and is thereby blocked, and preferably recovered. If the gas flow goes from hot to cold, a heat front occurs that blocks cold. If the gas flow goes from cold to warm, a cold front occurs that blocks heat.
    In the case of a cold front, the gas flowing through is heated, which costs heat energy, which is partly recovered from the diffuse heat flow, and in the case of a heat front, this heat can be lost to the outside. To limit this, it is preferable to keep the amount of gas flowing through the insulation assembly as small as possible, and / or to use a ventilation flow already associated with the interior space for the gas flow, and / or for the gas flow, the ventilation or air circulation of a heat pump. to use. It is also conceivable to recover the heat with a heat pump.
    The flow of the gas through the space between the top film and the bottom film is preferably laminar. This is possible in practical terms due to the presence of small through-flow openings, for example pores or perforations, in the perforated upper film and the lower film in combination with the large surface area of these films. As a result, the gas flow rate can be very low and the gas flow in that space between the perforated films laminar. This prevents disturbing thermal and / or convective turbulence in that space, and thus also a disruption of the described blocking action. This favorable effect is especially practicable if thermal stratification occurs in the gas-flow-through space between the perforated foils, for example, if in that gas-flow-through space the top is warmer and the bottom is colder. This is often the case with a (crawl) space under the floor of an interior space.
    Heat speed is a diffuse quantity, which depends on the average path length and the speed of the molecules in a medium, here a gas. It can be determined from the Peclet number Pe, which is greater than 1 if the convective flow is greater than the diffuse flow. In formula form: Pe = v I p Cp / λ, where v = gas velocity perpendicular to the surface of the flow-through space between the perforated films, I = path length through the
    -5 permeable space and thus the distance / height between the perforated bottom film and the perforated top film, p = the density of the gas flowing through, Cp = the heat capacity of the gas flowing through and λ = the heat conductivity coefficient of the gas flowing through.
    As the Pe number of the flowing gas becomes larger, the flow of the conductive heat becomes more blocked and the effective conductivity coefficient becomes smaller and the insulation of the insulating assembly becomes better.
    The insulation assembly and the fan system are preferably arranged such that a Peclet number Pe greater than 0, preferably greater than 1, more preferably greater than 3, is achieved in the gas flow through the space between the perforated upper foil and the perforated lower foil. wherein the Pe number is determined from the velocity component v of the flowing gas, which runs parallel to the heat flow, the thickness / height of the flowable space between the perforated upper film and lower film, the specific heat Cp, the specific mass p g , the specific mass p g , the thermal conductivity coefficient A g of the gas flowing through:
    Pe = v I Cp p g / A g .
    Depending on the height of the flow-through space, the flow-through speed with air can be, for example, between 0.05 - 4 mm / s and thus 0.05 - 4 liters / s per m 2 horizontal cross-sectional area of the flow-through space of the assembly.
    In one embodiment, a fan, for example via a tube or hose, pumps outside air from outside into the under-cavity of the insulation assembly. This air heats up through recuperation in the flow-through space and flows via the upper cavity warmed to the interior space, for example as heated fresh ventilation air. If the used ventilation air is discharged from that interior space, the heat contained in that used ventilation air can be recovered with a heat pump, so that virtually no heat is lost at the expense of some power consumption from the heat pump and the fan. This power consumption is only a small part of what is used without heating and therefore a huge saving on energy costs. For example, with an Rc value of 20 Km 2 / W of the insulation assembly, a ground temperature of 10 ° C and a floor temperature of 20 ° C, only 30 W is lost with a floor area of for example 60 m 2 . With a ventilation of 40 m 3 / hour the air at an outside temperature of 0 ° C must be heated with 267 W and with the loss of the floor this is approximately 297 W and there is
    -6 a COP of 5 only an electrical power of 59 W needed to recover the heat from the floor and the ventilation.
    In another embodiment there is furthermore a circulation passage which is connected to the bottom opening and to the top opening. This circulation passage forms a closed gas circuit with the lower cavity, the gas-flow-through space, and the upper cavity. The fan system herein comprises a fan associated with the circulation passage, which circulates gas present in the closed gas circuit and causes a displacement of the gas through the gas-permeable space, from bottom to top or from top to bottom or optionally in either direction . Air can be circulated in a closed gas circuit, but it can also be a gas other than air, for example carbon dioxide gas.
    In an exemplary embodiment in which the circulation of the flowing gas is closed, the gas is displaced by means of a fan through an evaporator part of a heat pump, for example sucked, and transported through the evaporator part cooled to one of the under-cavity or the upper cavity, depending on the desired influence. of the indoor climate.
    In a possible embodiment, the cooled gas coming from the evaporator part is transported to the bottom cavity. From there, the gas, possibly warmed by the contact of the under-cavity with the ground, flows to the flowable space, in which it further warms up during the flow from below to bottom through recuperation with the conduction heat. Arrived in the upper cavity, the gas is transported back to the evaporator part of the heat pump, where the absorbed heat is extracted again and after which the circulation is closed and starts again. This heat pump brings the absorbed heat to a condenser part of the heat pump, where this heat can be delivered at a higher temperature, for example to a heating system, such as underfloor heating, hot air heating, boiler, or other heating or heat storage. The heat pump thus supplies net heat energy from the ground beneath the interior space and the conduction heat which would be lost by the floor is fully recovered. If the ventilation of the interior space is, for example, provided by a balance fan, then with a balance efficiency of 70% at 40 m 3 / hour only 80 W is needed and with a heat pump capacity of 297 W only 217 W remains to heat the rest of the interior space , which is more than sufficient when applying good wall and window insulation and the internal heat production of people and equipment. Even then only 59 W of electrical energy is needed for a small and cheap heat pump, while the flow-through insulation assembly also requires only a small investment.
    -7 During the heating season, the temperature of the ground, due to the large heat content and the small uptake, drops by only 1 K and can be more than raised to its original level in the summer.
    If it is desired to heat the inner space with the heat pump, then a possible embodiment provides for the cooled gas coming from the evaporator part to be transported to the bottom cavity. From there, the gas, possibly warmed by the contact of the under-cavity with the ground, flows to the flowable space, in which it further warms up during the flow from below to bottom through recuperation with the conduction heat. Arrived in the upper cavity, the gas is transported back to the evaporator part of the heat pump, where the absorbed heat is extracted again and after which the circulation is closed and starts again. This heat pump brings the absorbed heat to a condenser part of the heat pump, where this heat can be delivered at a higher temperature, for example to a heating system. In practice, this solution requires only a very small heat pump, orders smaller than currently provided for heat pumps that are provided for heating interior spaces. In particular, the invention provides for the possibility of utilizing the heat pump's circulation fan as part of the fan system and thereby effecting the gas flow through the insulation assembly, whereby a better insulation of the insulation assembly is achieved. The integration with a heat pump according to the invention also makes it possible in some cases to dispense with the known outdoor unit of a heat pump that extracts heat from the outside air.
    If it is desired to cool the interior space in the system with a heat pump and a closed gas circuit, the direction of the gas flowing through is reversed and the floor of the interior space is cooled and the floor under the interior space is heated when the under-cavity makes contact with it . The heat that is released in the condenser section of the heat pump can then be used for things such as hot water, for example stored in a boiler, heat storage, or other useful applications.
    The films of the insulation assembly are airtightly connected at the periphery, such as with an air mattress. For example, the bottom wall film, the perforated bottom film, the perforated top film, and the top wall film are directly and airtightly connected to each other. An airtight connection is obtained, for example, with the aid of glue or welding.
    In a possible embodiment, the circumference of the gas-tight chamber is formed by a circumferential wall, to which the upper wall, lower wall and the perforated foils adhere airtightly at their circumference. Preferably, said circumferential wall is foldable, so that the insulation assembly can be collapsed into a foil package and optionally rolled up and / or folded up. Preferably, said peripheral wall is made of foil, for example the same foil as the top wall and the bottom wall. For example, the circumferential wall has a height that corresponds to the intended maximum distance between the perforated upper foil and the perforated lower foil.
    In a further embodiment, the insulating assembly has a further foil under the bottom wall, which foil is airtightly connected at the circumference and bounds a third cavity under the bottom cavity with the bottom wall. In operation, a medium other than the gas supplied by the fan system can flow through the third cavity, which medium then exchanges heat with the gas flowing through the under-cavity. This other medium can, for example, be groundwater, which can provide additional heat if the interior space has to be heated and if additional cooling is required for the interior space. Because a heat pump can extract more heat from the groundwater, the circulation can be increased and the conductive heat loss through the flow-through insulation assembly virtually goes to zero, while the heat pump then reduces the heating and cooling of the entire building including the interior space above the can provide crawl space.
    Equipment can be placed in, before or after the top opening and / or the bottom opening, with which the flowing gas is subjected to a pre-treatment or after-treatment, such as, for example, selected from the list of one or more filters, one or more gas absorbers, one or more humidifiers, one or more dehumidifiers, etc. This makes it possible, for example, for the flowing gas to be usefully used and not to contaminate or block the flowable space and the cavities.
    In a more possible embodiment of the method, the upper cavity is warmer than the lower cavity, as a result of which thermal stratification occurs, in particular in the gas-through space between the perforated upper foil and perforated lower foil. This is favorable because this stratification counteracts the occurrence of undesired turbulences that can negatively influence the blocking effect.
    The invention further relates to a climate control system according to claim 13 for controlling an indoor climate of an indoor space, for example according to the method as herein
    -9 described, which inner space is partially bounded by a floor, wherein under the floor there is an underfloor space, for example a crawl space.
    In a possible embodiment, for example in the situation in which the upper cavity is warmer than the lower cavity but possibly also in other situations, the space between the perforated upper foil and perforated lower foil is empty. Possibly there are threads or the like in that space which limit a maximum distance between the perforated films. Such wires or the like can also be provided in one or both cavities of the ventilation assembly.
    Due to the presence of thermal stratification in the gas-through space between the perforated upper film and perforated lower film, the presence of a porous insulating material as described in WO2019017784 and as provided therein to prevent thermal and flow turbulence can be omitted there. Therefore, in the context of the present invention, that space may be empty, which is preferred.
    In a possible embodiment, the insulation assembly is designed as a roll-up and / or foldable film package with a package of films piled on top of each other. In one embodiment, the foil package can be rolled out under the floor and inflated by the fan system, for example where the insulation assembly then unfolds as an air mattress. Optionally, the foil package has tubular spaces that are inflatable to serve as reinforcing ribs, as is known from inflatable tents.
    A roll-up and / or foldable embodiment of a foil package makes it possible, for example, to have the foil package collapsed again after the fan system has been turned off, for example under the influence of gravity. The collapsed insulation assembly can then possibly be rolled up and / or folded up again, and installed again later.
    For example, it is provided that the insulation assembly is designed as a foil package, wherein for performing work under the floor, the fan system is turned off so that the foil package collapses and access is made under the floor for performing those activities. The insulating assembly is preferably walkable in that collapsed state. Optionally, the collapsed package is rolled up and / or folded.
    The invention also relates to a building provided with an inner space which is partially bounded by a floor, wherein under the floor an underfloor space, for example a
    -10 crawl space, is present, which building is provided with a climate control system according to the invention.
    The invention also relates to a method according to claim 20 for installing a climate control system, wherein the insulation assembly is brought into the space below the floor, for example in the crawl space, in the collapsed state, optionally rolled up and / or folded, wherein the insulation assembly is placed in said space. room is inflated with the help of a fan, possibly first rolled out or unfolded, possibly placed on the bottom of the room.
    The invention will be explained below with reference to the figures. Hereby shows:
    FIG. 1 shows a schematic section of a flow-through insulation assembly according to the present invention;
    FIG. 2 shows a schematic section of a second application of a flow-through insulation assembly according to the present invention;
    FIG. 3 shows a schematic section of a third application of a flow-through insulation assembly according to the present invention;
    FIG. 4 shows a schematic cross-section of a detail of an embodiment of a flow-through insulation assembly according to the present invention.
    Figure 1 schematically shows a building 30 with side walls 31, 32, and roof 33, and in the building 30 an inner space 8. The inner space 8 is partially bounded by a floor 7.
    Below the floor 7 there is an underfloor space 34, here a crawl space with a bottom and below that the ground 14.
    In the space 34 there is an exemplary embodiment of a flow-through insulation assembly 1 according to the invention. The insulation assembly 1 has a gas-tight chamber with a top wall 3, a bottom wall 2, and a circumference 23, here with peripheral wall 36. The top wall 3, the bottom wall 2, and the peripheral wall 36 are each substantially formed by a gas-tight foil. Furthermore, a perforated upper foil 11a and a perforated lower foil 11b are arranged in the gas-tight chamber.
    The upper wall 3, the lower wall 2, the upper foil 11a, and the lower foil 11b are airtightly connected at the circumference, here with peripheral wall 36, of the gas-tight chamber, so that between the perforated upper foil 11a and the upper wall 3 there is an upper cavity 6 of the insulation assembly bounded between the perforated bottom foil 11b and the bottom wall 2 is an under-cavity of the insulation assembly, and between the perforated
    11 upper foil 11a and perforated lower foil 11b is defined as a gas-flowable space 4 surrounded by circumferential wall 36.
    As is preferred, the space 4 is empty, so free of a filling with porous material. The same applies to the cavities 5.6.
    The insulation assembly 1 has an upper opening 10, which connects to the upper cavity 6, and a lower opening 9, which connects to the lower cavity 5.
    In this example, the bottom opening 9 is connected to the outside air, for example via a tube and / or hose. The top opening 10 is here connected to the interior space, possibly with a ventilation system for the interior space 8.
    For effecting a flow of gas, here air, through the insulation assembly, a fan 13 is provided. In this example, the fan 13 is connected to the bottom opening 9.
    The insulation assembly 1 is here embodied as a rollable and / or foldable foil package with a package of superimposed foils, here the upper wall 3, the lower wall 2, the perforated upper foil 11a and the perforated lower foil 11b, wherein, preferably, the through-flow space between the perforated films 11a, b and surrounded by the peripheral wall 36 is empty.
    The insulation assembly 1 is, for example, brought into the space under the floor, for example in the crawl space, in the collapsed state, optionally rolled up and / or folded.
    Once in that space, the insulation assembly 1 is inflated with the aid of a fan, possibly after first being rolled out or unfolded. Here the insulation assembly is laid on the floor of the room. The fan 13 can optionally already be used during the installation of the assembly.
    After inflating, it is realized here that the top wall 3 sits under or against the floor 7 of the inner space 8 and the bottom wall 2 lies on the bottom of the space 34 and thus on ground 14. This fully or partially fills the crawl space.
    The flow of the flowing gas is indicated here by a streamline 12 in the form of a dotted line, which is indicated here in the heating state of the
    -12 climate control and which is the other way around in the cooling state. The gas flow can be both upwards and downwards, depending on the desired climate in the inner space 8.
    In this example, outside air is sucked in with the fan 13 and pumped into the lower cavity 5 via that opening 9. The air then passes through the perforated lower foil 11b associated with that cavity 5. The gas then enters the gas-flowable space 4 between the lower film 11b and the upper film 11a, and flows upwardly through that space 4, and then leaves that space 4 through the perforated upper film 11a. The gas then flows into the upper cavity 6 and leaves that upper cavity and the gas-tight chamber via the upper opening 10 and enters the inner space 8. In a possible embodiment, the fan system is only capable of realizing this flow from below to the top. As mentioned, the fan system can also be arranged to optionally, depending on the intended climate control, allow the flow through the insulation assembly to take place from bottom to top or from top to bottom. In all cases, the gas flows into the flow-through space 4 almost parallel to the heat flow, which can block the heat or cold.
    As described, as the Pe number of the flowing gas becomes larger, the flow of conductive heat becomes more blocked and the effective conductivity coefficient becomes smaller and the insulation of the flow-through insulating assembly 1 becomes better.
    Equipment can be placed in, before or after openings 9 and 10 to treat the flowing gas before or after, such as pumps, fans, filters, gas absorbers, humidifiers, dehumidifiers, etc., so that the flowing gas can be used effectively and the flowable gas Do not contaminate or block the insulation package 1 and the cavities 5 and 6.
    In Figure 2, components corresponding to Figure 1 are provided with the same reference numerals. Figure 2 again shows the building 30 with the insulation assembly 1 in the crawl space 34 below the floor 7.
    In contrast to the "open circulation" in Figure 1, this is a version with a closed gas circuit.
    In this embodiment a circulation passage 40 is present which connects to the bottom opening 9 and to the top opening 10. That passage 40 forms with the under-cavity 5, the pre-gas
    -13 throughflowable space 4, and the upper cavity 6, a closed gas circuit. In general terms, the fan system has a fan 13 associated with circulation passage 40 which circulates gas present in the closed gas circuit, thus in and out of the assembly 1, and causes movement of the gas through the gas-permeable space 4, from below to the top or from top to bottom.
    Also to be seen in this example is a heat pump 15 with an evaporator part and a condenser part. It is shown schematically here that the gas circulating in the closed gas circuit flows through an evaporator part of the heat pump 15 and thereby exchanges heat.
    It has been shown here that the heat pump 15 has a fan 13 which causes the gas to flow through the evaporator part and which forms part of the fan assembly.
    The flow of the gas flowing through is indicated by a streamline 12 in the form of a dotted line, which is indicated here in the heating state and which is reversed in the cooling state. The flow through the assembly 1 can, depending on the desired climate in the inner space 8, be directed both upwards and downwards.
    The flow-through insulation assembly 1 is connected to the evaporator part of a heat pump 15 and thereby exchanges heat. If the inner space 8 is to be heated, the fan 13 presses the cooled flowing gas from the evaporator to the bottom cavity 5 and absorbs heat from the ground 14 below the crawl space 34. The gas then passes through the flow-through insulating assembly 1 to the upper cavity 6 and is further heated up by recovering the conductive heat that the assembly 1 wants to flow down. The gas then flows again via the upper cavity 6 to the evaporator of the heat pump 15, where it is further cooled such that it is colder than the temperature of the ground 14 and after which the closed cycle is repeated. In the lower cavity 5 it is therefore colder than the ground 14 and only heat can flow from the ground 14 to the lower cavity 5 and the flow of the conductive heat from the floor 7 to the ground 14 is completely blocked. Thus, the air circulation of the air heat pump 15 is used to considerably improve the insulation of the insulation package 1 from the inner space 8. Furthermore, the heat pump 15 does not need an outdoor unit with filter and fan here and it extracts extra heat from the ground 14.
    The heat absorbed by the heat pump 15 is transferred through a condenser thereof according to the indicated flow lines 16 to a non-drawn one
    -14 heating system, such as, for example, underfloor heating, hot air heating, or on a boiler or other heat storage.
    If the inner space 8 is to be cooled, the fan 13 presses the cooled flowing gas from the evaporator part to the upper cavity 6 and the gas absorbs heat from the floor 7, which floor 7 and therefore also the space 8 are cooled thereby. Subsequently, the gas passes through the flow-through insulating assembly 1 to the under-cavity 6 and the gas is further heated by the conductive heat that wants to flow down through the assembly 1. It then flows to the under-cavity 5 where the gas releases its heat to the ground 14 and the gas then flows to the evaporator of the heat pump 15, where it is further cooled and after which the closed cycle is repeated.
    The heat absorbed by the heat pump 15 is transferred by means of its condenser along the indicated flow lines 16 to a system (not shown), such as for example a boiler or other heat storage.
    In Figure 3, components corresponding to Figures 1 and / or 2 are provided with the same reference numerals. Figure 3 again shows the building 30 with the insulation assembly 1 in the crawl space 34 below the floor 7.
    In the embodiment of Figure 3 there is talk of an insulation assembly T which has a further film 20 below the bottom wall 2 of the part further corresponding to insulation assembly 1, which foil bounds with the bottom wall 2 a third cavity 21 which is located below the under-cavity 5. A medium other than the gas displaced by the fan system is here flowed through the third cavity 21, for example groundwater, which medium exchanges heat with the gas in the under-cavity and with the ground 14.
    For example, ground water is pumped via the opening 37 through the additional cavity 21 via a pump 35 and led to the opening 38, where it is discharged again. Other options are, for example, hot, used ventilation air, bath or shower water, solar boiler heat, etc., whereby this heat is also stored in the ground 14, if it is not necessary, for later useful use by the heat pump 15.
    The flow of the gas flowing through is indicated here by a streamline 12 in the form of a dotted line, which is indicated here in the heating state and which in the cooling state is the other way around. The flow can be both upwards and downwards, depending on the desired climate in the inner space 8.
    -15 The flow-through insulation assembly 1 is connected to the evaporator of heat pump 15 and thereby exchanges heat. If the inner space 8 is to be heated, the fan 13 presses the cooled flowing gas from the evaporator to the bottom cavity 5 and the gas exchanges heat with the extra medium in the cavity 21, such as, for example, groundwater indicated by the streamline 22 in the additional cavity 21. and possibly also with the ground 14 under the bottom of the crawl space under the floor 7 of the inner space
    8. Subsequently, the gas passes through the flowable insulating assembly 1 to the upper cavity 6 and is further heated by the conductive heat which wants to flow down through the assembly 1. The gas then flows again via the upper cavity 6 to the evaporator part of the heat pump 15, where the gas is further cooled such that it is colder than the temperature of the additional cavity 21, after which the closed cycle is repeated. In the lower cavity 5 it is thus colder than the additional cavity 21 and only heat can flow from the additional cavity 21 to lower cavity 5 and the flow of the conductive heat from the floor 7 to the additional cavity 21 is completely blocked.
    Thus, the air circulation of the air heat pump 15 is used to considerably improve the insulation of the insulation package 1 from the inner space 8. Furthermore, the heat pump 15 does not require an outdoor unit with filter and fan and it extracts extra heat from the extra medium in the extra cavity 21 and possibly also from the ground 14.
    The heat absorbed by the heat pump 15 is transferred by means of the condenser according to the indicated flow lines 16 to a heating system (not shown), such as for example underfloor heating, or to a boiler or other heat storage.
    If the inner space 8 is to be cooled, the fan 13 presses the cooled flowing gas from the evaporator part of the heat pump 15 to the upper cavity 6 and absorbs heat from the floor 7, which is cooled thereby. Subsequently, the gas passes through the flowable insulation package 1 to the under-cavity 5 and the gas is further heated by the conductive heat that wants to flow down through the assembly 1. The gas then flows through the under-cavity 5 where it transfers its heat to the additional cavity 21 and possibly the soil 14, and the gas flows to the evaporator of the heat pump 15, where it is further cooled and after which the closed cycle is repeated.
    The heat absorbed by the heat pump 15 can then be transferred via the condenser to a system, such as for example a boiler or other heat storage.
    Figure 4 shows a schematic cross-section of a detail of an embodiment of the flow-through insulation assembly according to the present invention. The bottom wall 2, the top wall 3, and the perforated films 11a, b of the insulation package 1 are here kept at a maximum distance with wires 17 relative to each other when the closed flow-through space 4 is unfolded by the circulation fan by being inflated.
    At the periphery 23 of the insulation assembly 1, the peripheral wall 36, the bottom wall 2, the top wall 3, and the perforated films 11a, b are airtightly connected to each other, for example with an adhesive, weld, or sewing joints.
    If the insulation assembly 1 is only used for heating purposes where the air flow is upward, in a suitable embodiment the perforated films 11a and 11b will float in the perforations due to the air resistance and no wires 17 are required.
