Definitions

• the present invention relates to a device for counteracting the flow of heat through a wall which divides off a primarily enclosed room with a temperature diverging from that of its environment.
• a prerequisite for achieving good indoor climate is also that of avoiding excessively large differences in temperature between the ceiling and floor of the room and the rapid drop in temperature that occurs in the case of poorly insulated walls.
• the present invention relates to a device which fulfils the afore- mentioned desiderata and solves the problems discussed above.
• the inventions relates to a device in conjunction with a wall that forms part of a delimitation of a primarily enclosed room with re-
• Apertures are disposed in the lower and upper part of the wall that connect the columnar space to the region of higher air temperature.
• a device e.g. a fan, for preferably con- tinous supplying of air to the columnar space, by which means air passes through the columnar space and out through the lower aper ⁇ tures, at the same time as part of the air is also forced into the insulation via the aforementioned air-distributing layer.
• the afore ⁇ mentioned flow of air into the insulation achieves what is termed counterflow or dynamic insulation, which involves a considerable lowering of the u-value.
• devices are disposed insided the columnar space, e.g. spacer blocks, ribs, fibreglass fabric etc, which disturb the flow of air through the gap and thereby cause turbulence therein, which in turns improves the necessary flow of air into the insulation and thus the desired improvement in the overall insulation of the wall, which can be measured through a considerably lower u-value.
• the air-supplying device (fan) is connected to a primarily enclosed compartment disposed in conjunction with the ceiling of the room and usually constituting its upper delimitation.
• One or several apertures are disposed between the com-
• the embodiment described in the preceding paragraph is supplemented by an air filter and/or a dehumidifier, alternative ⁇ ly, a humidifier.
• heating devices are also disposed in conjunction with the compartment. Since the invention results in a considerable improvement to the insulation of the wall, it is often sufficient to make use solely of the waste heat that is produced by lighting in order to attain the required room tempera ⁇ ture.
• each room comprises a separate unit, by means of which the risks of a spread of fire, smoke or gases in the case of central fan systems are completely avoided.
• fig. 1 which shows a partial section through a wall and a room.
• the figure depicts an embodiment of the invention in which a room 10 has an upper delimitation 11 comprising the ceiling of the room.
• a wall 20 is connected to the upper delimitation of the room. Seen from the outside, the wall is disposed in the conventional manner with a windtight layer, where required, an air layer, which is followed by one or several layers of insulating material 28. These parts of the wall are however omitted from the figure with the excep ⁇ tion of the insulating material which is partially shown in the figure.
• an air- -distributing layer 29 In the direction of the room there then follows an air- -distributing layer 29, a columnar space 21 and a primarily airtight layer 41 whose side facing closest to the room forms the delimiting surface 22 of the wall with respect to the room.
• Apertures 23 into the room 10 are disposed in conjunction with the lower part of the columnar space 21, and in conjunction with the upper part of this space there are disposed apertures 24 which open into a compartment 31 whose lower part forms the upper delimitation 11 of the room.
• devices 25 for disturbing the air current and for achieving turbulence therein. Examples of such devices are spacer blocks, ribs, fibreglass fabric etc.
• the compartment 31 contains a device 30 for supplying air to the columnar space 21 through the aforementioned upper apertures 24. There are then disposed one after the other an air filter 33, a humidifier 34 and a heating device 32 as well as a dehumidifier 35. It can be seen from the figure that the aforementioned devices form an enclosed duct one end of which opens into the compartment 31 and the other end is connected to the upper apertures 24 in the delimita ⁇ tion of the columnar space 21. This thus ensures that once the treatment of the air in the aforementioned devices has been com ⁇ menced, no untreated air is mixed with the air that is supplied to the columnar space 21.
• the invention in its simplest form is applicable only with the employment of the device 30 for direct supplying of air to the columnar space 21.
• the compartment 31 is, in the embodiment shown, disposed in its lower part in.the delimitation 11 towards the room 10 with apertures 12 through which air passes into the compartment 31.
• the figure also shows a ventilation duct 26 connected to a fan device 27 for connecting the room 10 to the environment. This means makes it possible to undertake the supplementary changes of air between the room 10 and the environment which may be required.
• the figure also shows a delimitation wall 42 placed in the compart ⁇ ment 31.
• the delimitation wall 42 is used in those embodiments where the compartment 31 collaborates with more than one wall and where several walls are disposed with columnar spaces 21.
• the thermal energy of this air layer is put to use, in that the air from the layer in question is supplied by means of the device 30 to the columnar space 21 through the upper apertures 24.
• warm air is sucked into the compartment 31 through the apertures 12 in the upper delimitation of the room and is then taken in turn through the de- humidifier 35, the heating device 32, the humidifier 34, the air filter 33, in order to then pass through the devicer 30.
• the device 30 of the devices enumerated is used. In this simple embodiment the air is thus taken directly from the compartment 31 or alternatively from the warm air layer below the ceiling of the room to the columnar space 21.
