The temperature inside the tank / storage can be measured. The temperature outside the tank / storage, ie. the ambient temperature can be measured.

    The medium to be provided in the insulation volume with adjustable thermal conductivity may comprise at least one of the following or a mixture of any of the following: a gas, a liquid, a pumpable medium, a viscous medium, air, water, a coolant, a crude oil component, a hydrocarbon.
    Two media can be arranged in the insulation volume. Liquids and gaseous media can be arranged in the insulation volume. A gasifiable medium (eg a hydrocarbon, a coolant) can be provided in the insulation volume. Changing the thermal conductivity of the insulation volume can be effected by changing the pressure and / or the amount of medium. Liquids typically have a higher thermal conductivity than gases. To increase the thermal conductivity of an insulator, the volume of liquid in the insulation volume can be increased at the expense of the volume of gas. The thermal conductivity of the insulation volume can be increased or improved with circulating liquid in the insulation volume. To reduce the thermal conductivity of the insulator, the volume of gas in the insulation volume can be increased at the expense of the volume of liquid. According to some embodiments, when low insulation capacity is required, liquid is provided in the insulation volume, and when higher insulation capacity is required, the liquid or part of the liquid is removed from the insulation volume and a vacuum is sucked into the insulation volume. The amount of vacuum can be adjusted. In order to increase the thermal conductivity, the density of the medium arranged in the insulation volume, such as a gas or a gas mixture, can be increased by increasing the pressure on the medium. The thermal conductivity typically increases in the medium as the density of the medium increases. Comparably, conversely, to reduce the thermal conductivity of the insulator, the density of the medium arranged in the insulation volume can be reduced by increasing the pressure on the medium, thereby reducing the thermal conductivity of the medium.
    A heat-conducting / heat-insulating medium can be replaced in the insulation volume to adjust the thermal conductivity of the insulating / heat-conducting structure. The thermally conductive / insulating medium in the insulating volume can be completely replaced with another medium to adjust the thermal conductivity of the insulating / thermally conductive structure.
    Preferably, the insulating capacity of the insulation of the tank is adjusted by changing the pressure of the insulating volume outside the inner casing.
    Preferably, the insulating capacity of the insulation of the tank is adjusted by changing the pressure of the insulating volume outside the inner casing. A pressure corresponding to that in the environment can be arranged in the insulation volume.
    Preferably, the insulating capacity of the insulation is increased by reducing the pressure of the medium in the insulating volume. In accordance with some embodiments, an overpressure of the medium in the insulation volume is reduced. the insulation volume can be pressurized. The underpressure in the insulation volume can be increased. A vacuum can be provided in the insulation volume.
    The value of the pressure arranged in the insulation volume, e.g. negative pressure, depends on, among other things, the thickness and shape of the wall of the insulation volume, such as the distance between the inner and the outer casing of the insulation volume. Preferably, the insulating capacity of the insulation is reduced by increasing the pressure on the medium in the insulating volume. In accordance with some embodiments, the negative pressure of the medium in the insulation volume is reduced. The insulation volume can be pressure translated. The overpressure in the insulation volume can be increased.
    The contents of the insulating structure can be cooled by reducing the insulating capacity of the insulating volume when the ambient temperature is lower than that of the contents of the insulating structure.
    The contents of the insulating structure can be heated by increasing the insulating capacity of the insulating volume when the ambient temperature is higher than that of the contents of the insulating structure.
    The insulating structure can be arranged as part of a tank or a warehouse.
    The warehouse and / or tank may be intended for storage of people, animals or goods. Equipment that produces heat can be stored in the warehouse and / or tank.
    The warehouse and / or tank can be a warehouse for the process industry and / or the food industry or a warehouse for pre-agriculture. The warehouse and / or tank may include, for example, equipment for energy distribution, electricity distribution, water distribution, sewage network, waste management, fuel distribution, data transmission or telecommunication network.
    By means of the adjustable insulation, the temperature of the material stored in the tank can be adjusted or stored. The temperature of the material stored can be raised and / or lowered. The temperature of the material to be stored can be kept constant. The ambient temperature, for example the temperature prevailing in nature, can be used to raise and / or lower the temperature of the material being stored. The variation in the ambient temperature, for example variation in daily temperature or seasonal variation of the temperature can be used in the insulation of the tank. In accordance with some embodiments, by utilizing the variation in the daily temperature in the environment of the tank, the need for heating and / or cooling can be reduced. Adjustable insulation enables energy to be saved. The thermal expansion and / or thermal contraction of the material in the tank or storage can be reduced. Changes in the stress state of the tank construction can be reduced.
    The principle of adjustable insulation, the insulating construction and the process presented in this description can be applied within the framework of, among others, the process industry and the food industry, as well as agriculture. By means of the insulating construction, the temperature of the material stored, the material fed into the process, or treated in the process can be reduced, maintained or increased in an energy efficient manner. In accordance with some embodiments, the tank may be used as a tank for decomposition processes, composting processes and fermentation processes.
    Thus, the heating and cooling effect obtained from the environment can be used in an energy efficient way in such biological processes. In biological processes, heat obtained from the outside of the tank can be used to activate a process, activating the function of bacteria, for example. Once the process has been activated, the temperature of the contents of the tank can be cooled to maintain a suitable operating temperature for the process by transferring heat from the outside of the tank if the temperature in the process increases to extreme, for example to the extreme effect of bacteria used in the process.
    The heat energy available in the vicinity of the tank / storage can be allowed to be transferred in an amplified manner to the contents of the tank and to raise the temperature of the contents of the tank so that the thermal conductivity of the insulation of the tank is adjusted to be higher. The heat energy available in the tank / storage can be allowed to be transferred in an amplified manner outside the tank and to reduce the temperature of the contents of the tank so that the thermal conductivity of the insulation of the tank is adjusted to be lower. 10 15 20 25 30 11 For example, the durability of fragile goods can be improved. The variation in temperature of the material to be stored can be reduced. The gasification and / or evaporation of gasifiable materials, such as fuels or waste, can be reduced or increased according to the application. By reducing the generation of gases, unwanted emissions to the environment of the tank can be reduced.
    The pressure of a gaseous medium can be increased to increase the thermal conductivity of the insulator, and the pressure of the gas can be reduced to decrease the thermal conductivity of the insulator. Reducing the pressure of the insulating gas to a level lower than the atmospheric pressure is particularly preferred, as even small pressure differences can enable significant differences in the thermal conductivity of the insulator to be obtained. Heat can be obtained from the surroundings into the insulation volume in an adjustable manner and / or heat can be transferred to the surroundings outside the insulation volume in an adjustable manner.
    As an example, an insulating structure with which the contents of a tank or storage are insulated against the influence of cold can be adjusted so that the insulator enables the transfer of heat from the outside into the contents. Correspondingly, an insulating construction that insulates against the influence of heat can be adjusted so that the insulator enables the transfer of heat from the contents in a reinforced manner outside the tank. Known solid insulation also prevents the transfer of heat when it would be more sensible not to insulate.

    Figure 1 shows a tank, comprising an inner casing 2 and an outer casing 3 arranged outside the inner casing. An inner surface 2 'of the inner casing 2 defines a receiving volume 4 of the tank 1 for the material to be stored. The inner surface 2 'of the inner casing 2 faces in the direction of the material to be stored in the tank 1. The material to be stored may be any substance or material, preferably surface material, such as gaseous, surface, semi-liquid, pumpable. viscous, powdery or granular materials. The material to be stored is not, as such, intended to be limiting of the invention. Figure 1 does not show the opening in the tank for moving the material between the inside and the outside of the tank 1. Figure 1 also does not show couplings, e.g. for the material to be stored, means for measuring quantities of material, a service hatch or the like, which typically belong to tanks.
    Metal and plastic materials have been used as materials in the tank. In Figure 1, the space defined by an outer surface of the inner casing and an inner surface of the outer casing is formed as an insulating volume 5, which completely encloses the inner casing. More or less medium has been arranged to be located in the insulation volume 5 through a channel 6. The insulating capacity of the tank 1 is arranged to be adjustable so that the thermal conductivity of the insulating volume 5 can be adjusted.
    In Figure 1, an outer surface 3 of the tank has been arranged within the range of action of the varying temperature of the environment, preferably outdoors.
    In the tank 1, an insulating construction comprises a wall construction with stud cover 2, 3, which encloses the material to be stored. The insulation volume 5 as an adjustable thermal conductivity is arranged between the housings 2, 3.
    Adjacent to the tank 1, which is presented as an example of the insulating construction, a vacuum pump 7 is provided, which is suitable for adjusting the pressure in the medium, the density of a medium and the amount of the medium being arranged as adjusting device 7 of the thermal conductivity. of the isolation volume 5. The operation of the vacuum pump 7 is controlled by means of a control means 8. The communication between the vacuum pump 7 and the control means 8 is marked with 8 '.
    Optionally, the internal temperature in the tank 1 can be measured with a first temperature sensor 9, which is preferably located inside the inner casing 2, and the measurement information therefrom is passed on to the control means 8 (dashed line 9 '). Optionally, the temperature outside the tank 1, i.e. the ambient temperature, is measured with a second temperature sensor 10, which is preferably located outside the outer casing 3 and the measurement information is passed from there to the control means 8 (dashed line 10 '). The measured temperature values can be processed in the control means 8. In the control means, an adjustment value for controlling the vacuum pump 7 can be determined based on measured temperature values. The control means enables the medium to be led in and out of the insulation volume 5 depending on the ambient temperature. The pressure information from the insulation volume 5 is transmitted from a pressure sensor 14 arranged in the insulation volume 5 to the control means 8 (dashed line 14 ').
    The agent can be led into and out of the insulation volume 5 depending on the ambient temperature. When the ambient temperature is lower than that of the contents of the tank 1, a gaseous medium can be reduced in the insulation volume 5 to cool the contents. When the ambient temperature decreases, the gaseous medium can be reduced in the insulation volume 5. When the ambient temperature is higher than that in the contents of the tank 1, the gaseous medium can be reduced in the insulation volume 5 to heat the contents. As the ambient temperature increases, the gaseous medium can be reduced in the insulation volume 5.
    The tank 1 comprises a vacuum-tight insulation volume 5 arranged outside the inner casing of a gaseous medium to be pressurized. The means to be arranged in the insulation volume 5 can be suppressed in an adjustable manner by means of the vacuum pump 7.
    To increase the thermal conductivity of the insulation volume, the density of the medium arranged in the insulation volume, such as a gas or a gas mixture, can be increased by increasing the pressure on the medium. Comparably, conversely, in order to reduce the thermal conductivity of the insulator, the density of the medium arranged in the insulation volume 5 can be reduced by increasing the pressure on the medium, whereby the thermal conductivity of the medium decreases. The insulation capacity of the insulation tank can be adjusted by changing the pressure on the insulation volume 5. A pressure corresponding to that in the environment can be arranged in the insulation volume. The insulating capacity of the insulating volume can be increased by reducing the pressure on the medium in the insulating volume. The insulation volume may be suppressed. The negative pressure in the insulation volume can be increased. A vacuum can be formed in the insulation volume. Preferably, the insulating capacity of the insulator is reduced by increasing the pressure on the medium in the insulating volume. In accordance with some embodiments, a negative pressure in the medium in the insulation volume is reduced. the insulation volume can be overpressured. The overpressure in the insulation volume can be increased.
    The thermal conductivity of the insulation volume can be increased by circulating liquid in the insulation volume.

    Figure 2 shows a bearing 11, comprising an inner casing 2 and an outer casing 3 arranged outside the inner casing. An inner surface 2 'of the inner casing 2 defines a receiving volume 4 of the tank 1 for the material to be stored. The inner surface 2 'of the inner casing 2 faces in the direction of a material intended to be stored in the bearing 11. As with the tank 1, the material to be stored may be any substance or material, preferably fl surface material, such as gaseous, fl surface, pumpable, viscous, powdered or granular materials. The material to be stored is not, as such, intended to be limiting of the invention. Figure 2 does not show an opening for transferring the material between the inside and the outside of the layer 11. In Figure 2, the space is defined between an outer surface of the inner casing and an inner surface of the outer casing formed as an insulating volume 5, which partly encloses the inner casing 2. the insulation volume 5 is defined by a divider 15, which is arranged in a pressure-tight manner between the inner and the outer casing. The space between the inner casing and the outer casing is divided so that the insulation volume 5 with adjustable thermal conductivity is on one side of the divider 15, on the upper side as shown in Figure 2, and on the other side is a compartment with fixed insulation 13. More or less medium has been arranged to be located in the insulation volume 5 through a channel 6. The insulating capacity of the tank 1 is arranged to be adjustable so that the thermal conductivity of the insulation volume 5 can be adjusted. Figure 1 has an outer surface 3 of the tank arranged in the operating range of the varying ambient temperature, preferably outdoors.
    The layer 11 is located partly in ground level 12, surrounded by a ground layer 16. The part of the layer 11 which is above ground is equipped with an insulation volume 5 which has adjustable thermal conductivity for a medium, arranged outside the inner casing 2. The casing part of the layer 11 below ground level 12, which is not directly within the range of the varying ambient temperature, is equipped with a fixed insulator 13.
    A vacuum pump 7 suitable for adjusting the pressure of the medium, the density of the medium and the amount of the medium has been provided as a means of adjusting 7 for the thermal conductivity of the insulating volume 5 in connection with the bearing 11, presented as another example of the insulating structure. is controlled by a control means 8 as in Figure 1.
    The pressure information for the insulation volume 5 is transmitted from a pressure sensor 14 to the control means 8 (dashed line 14 ').

    The control means enables the medium to be led into and out of the insulation volume 5 depending on the ambient temperature.
    Figure 3 shows a layer 21, which comprises two insulation volumes 5.1 and 5.2 separated from each other by a divider 15, the thermal conductivity of the insulation volumes 5.1 and 5.2 being adjustable. The layer 21 10 15 20 25 30 17 differs from the layer 11 in Figure 2 in that the insulation volume 5.2 with adjustable thermal conductivity has been arranged in place instead of the fixed insulator 13. A first pressure sensor 14.1 is arranged in the first insulation volume 5.1, from which the pressure information from the insulation volume 5.1 is forwarded to a control means 8 (dashed line 14.1 '). A second pressure sensor 14.2 is arranged in the second insulation volume 5.2, from which the pressure information from the insulation volume 5.2 is transmitted to a control means 8 (dashed line 14.2 ').
    The control means 8 can control a vacuum pump 7 to separately adjust the first insulation volume 5.1 through a first channel 6.1 and the second insulation volume 5.2 through a second channel 6.2. As an example of the operation of the layer, heat energy can be conducted to the contents of the layer 21 from the environment above ground level 12 in hot weather, advantageously amplified by solar radiation (for example, by reducing the insulation capacity of the insulation volume 5.1), and cooling can also be obtained from the soil layer 16 to cool the contents (for example by reducing the insulation capacity of the insulation volume 5.2). As another example of operation of the warehouse, heat energy can be conducted from the contents of the warehouse 21 to the environment above ground level 12 in cold weather, preferably in winter (eg by reducing the insulation capacity of the insulation volume 5.1). Consequently, the temperature of the contents of the storage 21 can be controlled in an energy efficient manner.
    Figure 4 shows a tank 31 comprising three separately adjustable insulation volumes 5.1, 5.2 and 5.3. The construction with adjustable insulation capacity shown in Figure 4 comprises a cylindrical tank 31 mounted in a vertical position. In connection with the first insulation volume 5.1 and the second insulation volume 5.2, reference is made to the description of Figure 3. A third insulation volume 5.3 is arranged below the second insulation volume, separated by a second divider 15 'and arranged within the operating range of the groundwater temperature in a groundwater storage 18. The boundary between a soil layer 16 closer to the ground level 12 and the groundwater layer 18 is marked with a dashed line 17. A third pressure sensor 14.3 is arranged in the insulation volume 5.3, from which the pressure information for the insulation volume 5.3 is transmitted (dashed line 14.3 ') to a control means 8, which is not shown in Figure 4.
    The control means 8 can control a vacuum pump 7 for separately adjusting the first insulation volume 5.1 through a first channel 6.1, the second insulation volume 5.2 through a second channel 6.2 and the third insulation volume 5.3 through a third channel 6.3.
    As an example, under certain conditions, the temperature may be about + 6- + 25 ° C in the environment around the tank 31 above ground, about + 6 ° C in the soil layer 16 and about + 4 ° C in the groundwater layer 18. The contents stored in the tank may be a dairy product. The contents of the tank 31 can be maintained at a temperature of about + 6-8 ° C as follows: a) when the temperature drops, the contents are heated by means of the insulation volume 5.1 by increasing the thermal conductivity of the insulation volume 5.1 (optionally the thermal conductivity of the third insulation volume 5.3), b) the temperature is maintained by means of a second insulation volume 5.2, and c) when the temperature of the tank contents increases, the contents of the tank are cooled by the third insulation volume 5.3 by increasing the thermal conductivity of the insulation volume 5.1. the thermal conductivity of the first insulation volume 5.1).
    A mixing device 19 can be arranged in the receiving volume 4 of the tank 31 to mix the contents of the insulating structure and to enhance the heat transfer between the contents and the outside of the tank.
    The mixing device may comprise a rotatable propeller. Openings in the tank are marked with reference numeral 20.
    A temperature sensor or sensors may be provided in connection with the ground layer in Figures 3 and 4, which can be used to measure measurement data to be transmitted to the control means 8 and to be processed by the control means 8 to generate an operating signal to an adjusting means. 7.
    At least two insulation volumes arranged to be separated from each other and with separately adjustable thermal conductivities can be arranged in an insulating construction to be renovated. the insulators or some of the insulators in an insulating structure that have been used (eg a tank, storage or container) can be replaced by the insulation volumes presented in this description, which are arranged to be separate and have separately adjustable thermal conductivity.
    As an example of arranging an insulating structure outside the inner casing, at least two visible insulation bags or liners may be mentioned, which are arranged to be separated from each other, have separately adjustable thermal conductivity, be arranged outside the insulating structure and designed in accordance with the shape of the insulating construction. The insulating liner or sack preferably has an adjustable insulating volume arranged between two walls. The insulation bag or liner can be filled with a medium. The insulation bag or liner can be arranged around a tank or container. Insulation bags or lining can be arranged side by side so that the difference from at least two insulation volumes is directed in markedly different directions in the receiving volume of the insulating structure intended for a material to be arranged in the insulating structure. In accordance with some preferred embodiments, at least two insulation volumes, arranged to be separate from each other and having separately adjustable thermal conductivity, are arranged in at least two different environments so that markedly different temperatures are directed towards the insulation volumes in the different environments. Thus, the temperature of the material to be arranged in the insulating construction can be adjusted between the (extreme) temperatures of the at least two different environments. In this way, the temperature of the material inside the insulating structure can be adjusted even without external energy. The adjustment of the temperature of the material to be stored can be taken care of very cost-effectively by utilizing the adjustable thermal conductivities of the insulation volumes located in the area of action of different environments.
