Description

METHOD FOR MOVING THERMAL ENERGY AND/OR MOISTURE IN A SHELL STRUCTURE OF A BUILDING AND A SHELL STRUCTURE

Field of the invention

The invention relates to a method for moving thermal energy and/or moisture in a shell structure of a building such as a roof or a facade as defined in the preamble of independent claim 1.

The invention also relates to a shell structure of a building such as a roof or a facade as defined in the preamble of independent claim 21.

The invention also relates to a method for heating a building as defined claim 39 and to a method for cooling a building as defined claim 43.

The invention relates to a method for moving thermal energy and/or moisture in the shell structure or the building envelope of a building (hereinafter "shell structure") and to a shell structure of a building, which shell structure is provided with means for moving thermal energy in the shell structure. By a structural part of a building is here meant the part(s) of the roof or the part(s) of the wall of the building not being the shell structure of the roof or the wall such as a load-bearing structure of the roof or the wall, a support structure of the roof or the wall, or a primary structure of the roof or the wall. Moving thermal energy means in this context that thermal energy is removed from the shell structure and/or moved inside the shell structure from one place to another. Moving moisture means in this context that moisture is removed from the shell structure and/or moved inside the shell structure from one place to another. Examples of parts of a building belonging to a building's shell structure are the roof and the facade. The word fluid used in this text refers to liquids such as cooling liquid and gases such as air and to mixtures of liquids and gases

Shell structures of buildings having ventilation channels for defining fluid paths inside the shell structure are known in the art. One known way to arrange such channels inside a shell structure is to form channels inside the insulation layer of the shell structure by making the insulation layer of insulation boards which are provided with elongate ventilation channels or elongate ventilation groves. ISOVER OL-K- TOP and OL-KA (producer Saint-Gobain Isover Oy, Finland) are a rigid insulation boards provided with open elongate ventilation grooves in one of the surfaces of the rigid insulation board. By using these known insulation boards can ventilation channels be formed inside the insulation layer by covering the surface provided with the open grooves of the rigid insulation board with another insulation layer so that closed channels having open ends are formed of the open grooves. The purpose of this known arrangement is to improve the removal of moisture from the shell structure.

Publication DE 198 45 557 Al discloses an air-circulation heating having has externally closed air circulation with air ducts integrated in insulating panels. A heat- reflecting layer has a vapor barrier on the inside of the insulating panel facing away from the building. A room-ventilation unit is integrated in the insulating panel's ventilating plane. The ventilation system incorporates fans, air filters, air de- humidifiers with one or more heat-exchanger elements and control and regulation unit. Publication DE 198 49 127 Al discloses a composite dynamic heating system consists of a multi-ply outer covering for the building, through which air flows. The inside of the building's outer has a layer through which air flows; the outside of the building's outer cover has one or two layers through which air flows The outer layer is chiefly for obtaining solar heat; the inner layer on the outside of the building's outer cover is mainly for obtaining heat transmission losses from the inner wall. The layer on the wall's inner side is for heating and ventilating the room. The two layers through which air flows on the outside of the wall are thermally separated by a layer. The air ducts are interconnected.

Publication DE 41 03 010 Al discloses a heat recovery system involving the use of a closed circuit of either air or liq. to surround a building. Cavities are formed by insulation and a ventilation shaft from the top to the bottom. The ventilator provides the forced circulation, and the air in the cavity under the roof is heated by the sun, shutters controlling the air flow.

The objective of the invention is to provide a new and inventive method for moving thermal energy and/or moisture in a shell structure of a building.

Another object of the invention is to provide a new and inventive shell structure of a building, which shell structure is provided with an arrangement for moving thermal energy and/or moisture in the shell structure.

Short description of the invention

The method of the invention is characterized by the definitions of independent claim 1.

Preferred embodiments of the method are defined in the dependent claims 2 The shell structure of the invention is correspondingly characterized by the definitions of independent claim 21.

Preferred embodiments of the shell structure are defined in the dependent claims 22 to 38. The invention also relates to a method for heating a building as defined claim

39.

Preferred embodiments of the method for heating a building are defined in the dependent claims 40 to 42.

The invention also relates to a method for cooling a building as defined claim 43.

Preferred embodiments of the method for cooling a building are defined in the dependent claims 44 and 45.

The invention is based on the idea that a flow means comprising a motor means and a fluid moving means operable by the motor means is functionally connected to channels inside the shell structure of the building for creating a flow of fluid in the channels. If the temperature of the shell structure surrounding the channels is higher than the temperature of the fluid flowing in the channels, thermal energy from the shell structure flows to the fluid flowing in the channels and as a consequence of this the temperature of the fluid flowing in the channels rises. This is due to the second law of thermodynamics according to which differences in temperatures in systems evens out which in this case means that thermal energy flows from the shell structure to the fluid in the channels, provided that the temperature if the shell structure is higher than the temperature of the fluid in the channels. By removing from the channels fluid, which temperature has been raised by thermal energy of the shell structure, can therefore thermal energy be removed from the shell structure in the form of thermal energy transferred from the shell structure to fluid flowing in the channels and as a result of this the temperature of the shell structure of the building is lowered. By moving in the channels fluid, which temperature has been raised by thermal energy of the shell structure, thermal energy can be moved inside the shell structure for example to warm up cold or colder parts of the shell structure.

The advantage of the invention is especially apparent in the summer when the shell structure of the building is heated by the sun. With preferred embodiments of the invention can at least partly such thermal energy, which otherwise could or would flow from the warmer shell structure to the colder interior of the building, be transferred away from the shell structure before it flows from the warmer shell structure into the colder interior of the building.

Preferred embodiments of the solution according to the invention reduces for example the need for using other means for preventing the temperature of the interior from rising such as air conditioning. Correspondingly, in the winter thermal energy accumulated in the shell structure for example due to sunshine can be transferred from the shell structure of the building to a structural part of the building and/or directly to the to and interior of the building or via a heat exchange to an interior of the building to reduce the need of using other heating means for warming up an interior of the building.

Preferred embodiments of the invention can also be used for moving thermal energy from or to the shell structure depending on the time of the day. During the evening of the night can thermal energy be moved from the shell structure of the building to a structural part of the building (provided that the temperature of the shell structure is higher than the temperature of the structural part for example due to solar radiation having heated up the shell structure during the day) to heat up the building during the evening or the night by thermal energy which otherwise would flow to the atmosphere surrounding the building.

In addition to remove thermal energy from a shell structure of a building, moisture can effectively be removed from the shell structure of a building by means of a solution according to the invention. If the moisture content of the shell structure surrounding the channels is higher than the moisture content of the fluid flowing in the channels, moisture from the shell structure flows to the fluid flowing in the channels and as a consequence of this the moisture content of the fluid flowing in the channels rises. By removing from the channels fluid, which moisture content has been raised by moisture from the shell structure, can therefore moisture be removed from the shell structure in the form of moisture transferred from the shell structure to fluid flowing in the channels and as a result of this the moisture content of the shell structure of the building is lowered.

This preferred embodiment of the method for heating a building 22 comprises a step for creating a fluid flow through said at least one additional channel 16 from the outside of the building 2 and back to the outside of the building 2 by controlling the motor means 13 of the flow means 12 with the control unit 31 provided than the temperature outside the building 2 measured by the first temperature sensor 26 is lower that the temperature of the fluid flowing inside said at least one additional channel 16 measured by the fourth temperature sensor 29.

A preferred embodiment of the method for heating a building 2 comprises a step for preventing a fluid flow between said at least one channel 7 and said at least one additional channel 16 and a step for preventing a fluid flow through said at least one channel 7 and said at least one additional channel 16 from the outside of the building 2 and back to the outside of the building 2 provided that the temperature outside the building 2 measured by the first temperature sensor 26 is higher than the temperature of the fluid flowing inside said at least one channel 7 measured by the third temperature sensor 28, and provided that the temperature of the fluid flowing inside said at least one additional channel 16 measured by the fourth temperature sensor 28 is lower than the temperature of the fluid flowing inside said at least one channel 7 measured by the third temperature sensor 28. Next the various ways of operating a structure comprising channels and additional channels that may be a wall or a roof and that is shown in figures 8 to 14 will be described in greater detail. The arrangements illustrated in figures 8 to 14 comprises a first temperature sensor 26 for measuring the temperature of the atmosphere surrounding the building 2, a second temperature sensor 27 for measuring the temperature of the surface of the shell structure 1, a third temperature sensor 28 for measuring the temperature of the fluid in a channel 7, a fourth temperature sensor 29 for measuring the temperature of the fluid in an additional channels 16, a fifth temperature sensor 30 for measuring the temperature inside the building 30, and a interface unit 32 for feeding a comfort value for the temperature inside the building eq. 2O⁰C to a control unit. The first temperature sensor 26, second temperature sensor 27, the third temperature sensor 28, the fourth temperature sensor 29, and the fifth temperature sensor 30 are preferably, but not necessarily, functionally connected to the control unit 31 for controlling the motor means 13 of the flow means 12 (not shown in figures 8 to 14) for creating fluid flows in the channels 7, for controlling the second flow means 18 (not shown in figures 8 to 14) for creating fluid flows in the additional channels 16, for controlling valves 23 (not shown in figures 8 to 14) arranged in the channels 7 and/or in the additional channels 16 for allowing and preventing fluid flows in the channels 7 and/or in the additional channels 16 and/or for allowing and preventing fluid flows between the channels 7 and/or the additional channels 16 and outside 25 of the building. It is obvious for a person skilled in the art that the arrangements illustrated in figures 8 to 14 need not to have all temperature sensors shown in the figures 8 to 14 to be able to function. Figures 8 to 11 relates to situations where the building needs heating. In figure 8 fluid i.e. air is drawn into the channels 7 formed in the shell structure 1 of the building 2 from the atmosphere surrounding the building.

The method shown in figure 8 can for example be employed in the morning for heating/warming up the shell structure 1 that has been cooled down during the night in a situation where the temperature of the atmosphere surrounding the building 2 is higher than the temperature of the shell structure 1 and/or higher than the temperature of the fluid in the channels 7. More precisely, when the sun rises in the morning, the temperature of the atmosphere surrounding the building 2 starts to rise. The temperature of the shell structure 1 of the building has however usually decreased during the night to a temperature that is lower than the temperature of the atmosphere surrounding the building 2 when the sun has raised the temperature of the atmosphere surrounding the building 2. By circulating air by means of flow means 12 (not shown in figure 8) from the atmosphere surrounding the building 2 in the channels 7 and back to the from the atmosphere surrounding the building 2 can the temperature of the shell structure 1 of the building be raised faster, because thermal energy of the air that is circulated in the channels is transferred to the cooler shell structure 1. The arrangement shown in figure 9 can for example function automatically so that when the control unit 31 notices that the temperature of the atmosphere surrounding the building 2 measured by the first temperature sensor 26 exceeds the temperature of the air in the channel 7 measured by the third temperature sensor 28, the control unit 31 controls the flow means 12 to circulate air from the atmosphere surrounding the building 2 inside the channel 7.

The method shown in figure 8 can for example be employed in the evening/night to slow down the cooling down of the shell structure 1. More precisely, when the sun sets in the evening thermal radiation is emitted from the surface of the shell structure 1 into the space provided that the sky is at least partly clear and the temperature of the shell structure is decreased. When the temperature of the shell structure has decreased to a temperature below the temperature of the atmosphere surrounding the building 2, air from the atmosphere surrounding the building 2 can be circulated in the channels 7 and back to the from the atmosphere surrounding the building 2 to slow down the decreasing of the temperature of the shell structure 1, because thermal energy of the air that is circulated in the channels 7 is transferred to the cooler shell structure 1.

Figure 9 is a variation of the situation shown in figure 1. In figure 2 fluid i.e. air is drawn from the atmosphere surrounding the building into the additional channels 16 formed in the shell structure 1 of the building 2 closer to the load- bearing structure of the building than the channels 7. The method shown in figure 9 can for example be done in the morning for heating/warming up the shell structure 1 that has been cooled down during the night in a situation where the temperature of the atmosphere surrounding the building 2 is higher than the temperature of the shell structure 1. This can for example be done in the morning for heating/warming up the shell structure 1 that has been cooled down during the night in a situation where the temperature of the atmosphere surrounding the building 2 is higher than the temperature of the fluid in the additional channels 16. More precisely, when the sun rises in the morning, the temperature of the atmosphere surrounding the building 2 starts to rise. The temperature of the shell structure 1 of the building has however usually decreased during the night to a temperature that is lower than the temperature of the atmosphere surrounding the building 2 when the sun has raised the temperature of the atmosphere surrounding the building 2. By circulating air from the atmosphere surrounding the building 2 in the channels 7 and in the additional channels 16 and back to the from the atmosphere surrounding the building 2 can the temperature of the shell structure 1 of the building be raised faster, because thermal energy of the air that is circulated in the channels 7 and in the additional channels 16 is transferred to the cooler shell structure 1. By circulating air additionally in the additional channels 16 (compare with figure 8) is thermal energy more effectively also transferred to the load bearing structure 14 of the building past the insulation 6. The arrangement shown in figure 9 can for example function automatically so that when the control unit 31 notices that the temperature of the atmosphere surrounding the building 2 measured by the first temperature sensor 26 exceeds the temperature of the air in the channel 7 measured by the third temperature sensor 28 and the temperature of the air in the additional channel 16 measured by the fourth temperature sensor 29, the control unit 31 controls the flow means 12 to circulate air from the atmosphere surrounding the building 2 inside the channel 7 and inside the additional channel 16.

In figure 10 fluid i.e. air is circulated between channels 7 and additional channels 16. This can for example be done during the day when solar radiation has heated up the shell structure 1 so that the temperature of fluid in the channels 7 that are closer to the outer surface of the shell structure 1 is higher than the temperature of the fluid in the additional channels 16 that are closer to the load-bearing structure of the building than the channels 7 and when the temperature of the atmosphere surrounding the building 2 is lower than the temperature of the fluid in the channels 7. In other words, in figure 10 is fluid not drawn into the channels 7 or into the channels 16 from the atmosphere surrounding the building 2, because the temperature of the atmosphere surrounding the building 2 is lower than the temperature of the fluid in the channels 7 and the temperature of the fluid in the additional channels 16 and because figure 10 relates to a situation where the building needs heating. By circulating air between channels 7 and additional channels 16 as shown in figure 10 thermal energy can be transported from the shell structure 1 to the load bearing structure of the building to decrease the need for heating up the inner space of the building. The arrangement shown in figure 10 can for example function automatically so that when the control unit 31 notices that the temperature of the atmosphere surrounding the building 2 measured by the first temperature sensor 26 is lower than the temperature of the air in the channel 7 measured by the third temperature sensor 28 and the temperature of the air in the additional channel 16 measured by the fourth temperature sensor 29, the control unit 31 controls the flow means 12 to circulate air inside between the channel 7 and the additional channel 16. In figure 11 fluid i.e. air is not circulated between channels 7 and additional channels 16, nor is fluid drawn into the channels 7 and/or into the additional channels 16 from the atmosphere surrounding the building 2, nor is fluid removed from the channels 7 and/or from the additional channels 16 to atmosphere surrounding the building 2. This can for example be done in a situation where the building needs heating such as during the night and where the temperature of the fluid in the additional channels 16 is higher than the temperature of the fluid in the channels 7 and where than the temperature of the fluid in the channels 7 is higher than the temperature of the atmosphere surrounding the building 2. The arrangement shown in figure 10 can for example function automatically so that when the control unit 31 notices that the temperature of the atmosphere surrounding the building 2 measured by the first temperature sensor 26 is lower than the temperature of the air in the channel 7 measured by the third temperature sensor 28, and that the temperature of the air in the additional channel 16 measured by the fourth temperature sensor 29 is higher than the temperature of the air in the channel 7 measured by the third temperature sensor 28, the control unit 31 controls the flow means 12 to not to create air flows inside the channel 7 or inside the additional channel 16 in order to not transport thermal energy from the additional channel 16 to prevent cooling of the structural part 14. Figures 12 to 14 relates to situations where the building needs cooling.

In figure 12 fluid i.e. air is circulated in the channels 7 and additional channels 16 from the atmosphere surrounding the building 2 back to the atmosphere surrounding the building 2. The method illustrated in figure 12 can for example be employed during the morning, day or evening when the temperature of the fluid in the channels 7 and the temperature of the fluid in the additional channels 16 is due to solar radiation having heated up the building higher than the temperature of the atmosphere surrounding the building 2. When fluid having a lower temperature than the temperature of the fluid in the channels 7 and the temperature of the fluid in the additional channels 16 is circulated in the channels 7 and in the additional channels 16 thermal energy flows from the shell structure 1 to fluid flowing in the channels 7 and in the additional channels 16 and as a consequence of this fluid flowing in the channels 7 and in the additional channels 16 is heated up. By removing such fluid from the channels 7 and from the additional channels 16 which fluid has been heated up by thermal energy of the shell structure 1 of the building thermal energy can be transported from the shell structure 1 to the atmosphere surrounding the building 2. The situation illustrated in figure 12 can for example be used in the summer in the morning or evening or during the day. The arrangement shown in figure 12 can for example function automatically so that when the control unit 31 notices that the temperature of the atmosphere surrounding the building 2 measured by the first temperature sensor 26 is lower than the temperature of the air in the channel 7 measured by the third temperature sensor 28 and the temperature of the air in the additional channel 16 measured by the fourth temperature sensor 29, the control unit 31 controls the flow means 12 to circulate air inside between the channel 7 and the additional channel 16 in order to transport thermal energy from the channel 7 and the additional channel 16 to cool down the shell structure 1 and the structural part 14.

In figure 13 fluid i.e. air is not circulated between channels 7 and additional channels 16, nor is fluid drawn into the channels 7 and/or into the additional channels 16 from the atmosphere surrounding the building 2, nor is fluid removed from the channels 7 and/or from the additional channels 16 to atmosphere surrounding the building 2. The situation illustrated in figure 12 can for example be used in the summer in a situation where the temperature of the atmosphere surrounding the building 2 is higher than both the temperature of the fluid in the channels 7 and the temperature of the fluid in the additional channels 16. The arrangement shown in figure 13 can for example function automatically so that when the control unit 31 notices that the temperature of the atmosphere surrounding the building 2 measured by the first temperature sensor 26 is higher than the temperature of the air in the channel 7 measured by the third temperature sensor 28, and the temperature of the air in the additional channel 16 measured by the fourth temperature sensor 29, the control unit 31 controls the flow means 12 to not to create air flows inside the channel 7 or inside the additional channel 16 in order to not transport any additional thermal energy from the atmosphere surrounding the building 2 into the channel 7 or into the additional channel 16 to prevent additional warming up of the structural part 14.

Figure 14 is a variant of the situation shown in figure 12. In figure 12 fluid is circulated in the additional channels 16 from the atmosphere surrounding the building 2 back to the atmosphere surrounding the building 2. This can for example be done in a situation where the temperature of the fluid in the additional channels 16 is higher than the temperature of the atmosphere surrounding the building 2. The situation illustrated in figure 12 can for example be used in the summer in the morning or evening or during the night. The arrangement shown in figure 14 can for example function automatically so that when the control unit 31 notices that the temperature of the atmosphere surrounding the building 2 measured by the first temperature sensor 26 is lower than the temperature of the air in the additional channel 16 measured by the fourth temperature sensor 29, the control unit 31 controls the flow means 12 to circulate air inside the additional channel 16 in order to transport thermal energy from the additional channel 16 to cool down the the structural part 14.

It is apparent to a person skilled in the art that as technology advances, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are therefore not restricted to the above examples, but they may vary within the scope of the claims.
