Definitions
- the present invention relates to an arrangement for improving ventilation indoors, which allows air flow from an air device to be preheated and distributed.
- the air devices comprise a complete unit made of sheet metal.
- the (overall) depth of the air devices varies as does their minimum height behind the radiator.
- radiators Since older radiators are usually fitted less than 22-30 mm from the wall and there is also often a window-sill, it is necessary to remove the radiator in order to be able to fit the outside air device. This necessitates extensive installation work.
- An object of the present invention is to partially or entirely solve the aforementioned problems by providing an arrangement which:
- this object is achieved by an arrangement for fitting between a wall and a radiator arranged on a wall in order to improve the indoor ventilation, which arrangement will allow an air flow to be heated and distributed and which has the characterising features specified in claim 1 below, with preferred embodiments being set forth in the dependent claims.
- the arrangement according to the invention is characterised in that it comprises a first part and a second part which are joined by a flexible duct made of a flexible material selected from a group comprising textile, rubber, rubberised fabric, film, or fibrous material.
- the air device improves indoor ventilation and allows incoming air to be heated and distributed. It is easy to fit the air devices behind a radiator without having to remove either the radiator or the window-sill, and the fact that the duct can be made to the desired length without affecting other functions makes it possible to adjust the air device to the height of the radiator.
- the first part is a filter box for filtering said air flow from an air inlet to the duct and having a filter hatch for changing the filter.
- the fact that the air flow contains particles such as pollutants and many different types of pollen means that for many people there is a great need to be able to filter out such substances which present problems, primarily for allergy sufferers but also for the public at large.
- the incoming air flow is filtered at an early stage and it is very easy to change filters and when necessary to clean the filter device.
- the second part comprises at least one expeller opening for expelling the air flow towards the radiator, the expeller opening moreover being designed to guide the air flow along the rear side of the radiator, which heats the incoming air flow and prevents cold draughts along the floor.
- the arrangement is designed so that the incoming air flow is delivered at high velocity and is angled upwards behind the radiator.
- a high velocity is important in order to prevent the cold air in wintertime "dropping" down below the radiator due to the high density of the air. If this should happen it results in cold draughts along the floor.
- Another important effect achieved by a high velocity delivered air flow is that the air flow then also expels the indoor air, that is to say it entrains the indoor air in proximity to the lower parts of the radiator. This means that warm indoor air mixes effectively with the cold outside air, which means that the temperature of the mixed air flow increases. This effect is particularly important in autumn and in spring when the temperature of the outside air may be low whilst the heating system is not in operation. During the heating period the air flow is also heated by the hot radiator.
- the air flow be allowed scope for proper warming by the radiator in that the air flow blows out towards the lower parts of the radiator. It is not effective, for example, to use an air device 230 mm behind a radiator which is 600 mm high. Since the arrangement according to the present invention allows the air flow to blow out against the lower parts of the radiator, this provides efficient heating of the outside air, since the air flow is forced to flow such a long distance along the radiator.
- the flexible duct is a substantially airtight fabric and the second part is suspended behind the radiator in the duct and the duct is suspended behind the radiator in the first part.
- the arrangement according to the present invention comprises three parts assembled into one unit.
- the arrangement has a depth, also known to the person skilled in the art as the overall depth, of approximately 17 mm, which corresponds to the minimum dimension encountered between radiator and wall. Its height behind the radiator is adjusted so that the largest possible proportion of the radiator is utilised.
- the first part 1 is referred to as a filter box. Fitted in this is a replaceable filter 10.
- a filter hatch 6 which may be insulated against condensation, is undone, providing access to the filter.
- a flexible and substantially airtight duct 3 is arranged in the lower edge of the filter box.
- substantially airtight means that the greater part of the air flow passes through the duct.
- the material for the duct can also be selected so that a minor leakage is permitted, which cannot be deemed to affect the functioning of the duct, however. It is intended that the duct material be selected according to requirements, a flexible material being chosen, that is to say a material such as textile, rubber, rubberised fabric, film, fibrous material.
- a second part 2 Arranged at the other end of the flexible duct 3 is a second part 2, which may also be known to the person skilled in the art as an expeller.
- expeller relates to a nozzle for blowing the air flow out and directing it, and which can be varied according to requirements. Other variants with equivalent characteristics may be used, however.
- the second part 2 is designed so that the incoming air flow is delivered at high velocity and is angled upwards behind a radiator 5.
- a high velocity is important in order to prevent the cold air in wintertime "dropping" down below the radiator 5 (due to the high density of the air). If this should happen it results in cold draughts along the floor.
- Another important effect achieved by a high velocity of the delivered air flow is that the air flow then also expels the indoor air. This means that warm indoor air mixes effectively with the cold outside air, which means that the temperature of the mixed air flow increases. This effect is particularly important in autumn and in spring when the temperature of the outside air may be low whilst the heating system is not in operation. During the heating period the air flow is naturally also heated by the hot radiator 5
- the design of the air device makes it possible to adjust the height of the air device so that the outside air is at all times delivered to the lower edge of the radiator 5.
- the duct 3 has an elongated cross-section.
- the duct 3 can be cleaned or replaced with a new one.
- the filter box 1 and the second part 2 can also be cleaned, for example, in a dishwasher, manually or by any other suitable method, so as to thereby clean the affected parts.
- the first part 1, the filter box comprises a box, the front side of which has an opening 7 in order to permit installation and changing of filters.
- the filter box 1 further more has a rear side which bears against a house wall which is provided with holes for the incoming air.
- In the rear wall of the filter box 1 there are holes 13 for fitting the filter box 1 to the house wall.
- the sealing strip prevents air from percolating out between the filter box 1 and the house wall.
- the opening 8 at the rear of the filter box 1 is somewhat over-dimensioned, the opening 8 being extra wide and high, in order to make the filter box 1 easier to install and adjust to the holes made in the house wall. It is possible to open up a number of holes in the house wall and the holes are not restricted to a particular size. However, the holes must be accommodated within the boundary of the rear opening 8 of the filter box.
- the filter hatch 6 for closing the front opening 7 of the filter box 1 is arranged at the front of the filter box 1. This means that the incoming air coming from the holes in the house wall is guided downwards towards the duct 3 and on to the second part 2.
- the filter hatch 6 also allows the filter 10 to be replaced or cleaned, as required.
- the filter box 1 is furthermore open at the bottom, where the duct 3 is intended to be fixed.
- the opening at the bottom allows the incoming air to flow towards the duct 3 and onwards to the second part 2, which is fixed to the other end of the duct 3.
- two of the longitudinal sides of the filter box 1 are preferably angled towards the front and rear side respectively of the filter box 1, which allows the duct 3 to be fixed to the filter box 1.
- Two grooves with rails reinforcing the grooves are correspondingly formed on the duct 3.
- the reinforced grooves of the duct 3 are bent backwards and pressed into the hooks formed by the backward angled parts 12 of the filter box 1.
- the first opening of the duct 3 is fixed to the lower opening of the filter box 1 and the second part 2 is accordingly fixed to the second opening of the duct 3 in the same way, using the same technique with which the duct 3 and the filter box 1 are connected to one another. It is possible to vary the height of the duct 3, that is to say the distance between the filter box 1 and the second part 2, so that the overall height of the filter device according to the present invention is adjusted according to the varying radiator heights encountered. Certain heights of radiators 5 are more common than others, however, which means that a standard height of air device will suffice for most radiator heights. For special designs of radiators 5 it is consequently very easy to adapt the air device to the height of the radiator 5 by using a suitable height for the duct 3.
- the ends of the duct 3 are respectively pulled or pushed towards the filter box or the second part 2.
- the reinforced grooves are bent outwards making it possible to pull the duct 3 free from the filter box 1 and the second part 2.
- the second part 2 has an opening 11 to the duct 3 and said backward angled parts 9 for fixing the second part 2 to the duct 3.
- the second part 2 also comprises at least one opening 4, an expeller, which is angled in order to allow the air flow from the duct 3 to be discharged towards the radiator 5 away from the floor and upwards. In this way the air flow is guided for a longer distance along the radiator 5, so that it is heated to the desired temperature and assumes a reduced velocity when the air flow leaves the radiator upwards and out into the room in which the air device and the radiator 5 are located.

Abstract
Description
- The present invention relates to an arrangement for improving ventilation indoors, which allows air flow from an air device to be preheated and distributed.
- Many dwellings that were built a number of years ago are largely equipped with ventilation systems of the natural draught or mechanical air discharge type. In these systems air is extracted from kitchens, toilets and bathrooms. Replacement air is taken in directly from outside via slit vents and fissures in the façade. Over time, the insulation of façades, etc., in a large number of buildings has been improved. This has meant that houses have become more impervious, thereby leading to a considerable deterioration in ventilation.
- On the other hand, mechanical air discharge has in recent years become the most common method of ventilation in dwellings. This relies on so-called outside air devices, which both filter and heat the outside air before it is delivered to the dwelling. This type of air device is fitted behind a radiator or the like and uses this as heat source for heating the outside air. Air devices are installed virtually throughout in all new buildings.
-
DE 20218457 U shows an example of such an outside air device, which is fitted behind a radiator and reveals all the features of the preamble of claim 1. - In older property it is often both difficult and expensive to improve the ventilation by means of efficient air devices, since the air devices comprise a complete unit made of sheet metal. The (overall) depth of the air devices varies as does their minimum height behind the radiator.
- In order to be able to fit these air devices without removing the radiator there must be at least 22-30 mm clearance between radiator and wall. Since the air devices must be lowered from the top between radiator and wall, there must not be any window-sill in the way. It is not feasible to insert these air devices from the side, since the radiator bracket gets in the way.
- Since older radiators are usually fitted less than 22-30 mm from the wall and there is also often a window-sill, it is necessary to remove the radiator in order to be able to fit the outside air device. This necessitates extensive installation work. First the radiator system has to be drained and the radiators in question removed. After making holes in the façade wall, the outside air device is fitted to the wall. The radiator must then be fixed to its brackets. In cases where it is necessary to increase the distance between radiator and wall, the pipework connection to the radiator will not fit. The pipes coming up from the floor or running along the wall then have to be bent so that these can be coupled to the radiator. Bending old pipes is not to be recommended since cracking can easily occur leading to problems of leakage.
- There is a need for an arrangement that will solve the aforementioned problems so as to be able to improve the indoor ventilation without the need for major intervention in existing installations...
- An object of the present invention is to partially or entirely solve the aforementioned problems by providing an arrangement which:
- improves indoor ventilation,
- allows incoming air to be heated and distributed,
- facilitates the fitting of an air device behind a radiator without having to remove either the radiator or the window-sill, and
- affords the facility for adjusting the air device to the height of the radiator.
- According to the present invention this object is achieved by an arrangement for fitting between a wall and a radiator arranged on a wall in order to improve the indoor ventilation, which arrangement will allow an air flow to be heated and distributed and which has the characterising features specified in claim 1 below, with preferred embodiments being set forth in the dependent claims.
- The arrangement according to the invention is characterised in that it comprises a first part and a second part which are joined by a flexible duct made of a flexible material selected from a group comprising textile, rubber, rubberised fabric, film, or fibrous material.
- Some advantages of the present invention are that the air device improves indoor ventilation and allows incoming air to be heated and distributed. It is easy to fit the air devices behind a radiator without having to remove either the radiator or the window-sill, and the fact that the duct can be made to the desired length without affecting other functions makes it possible to adjust the air device to the height of the radiator.
- According to one embodiment the first part is a filter box for filtering said air flow from an air inlet to the duct and having a filter hatch for changing the filter. The fact that the air flow contains particles such as pollutants and many different types of pollen means that for many people there is a great need to be able to filter out such substances which present problems, primarily for allergy sufferers but also for the public at large. With the present invention the incoming air flow is filtered at an early stage and it is very easy to change filters and when necessary to clean the filter device.
- According to one embodiment the second part comprises at least one expeller opening for expelling the air flow towards the radiator, the expeller opening moreover being designed to guide the air flow along the rear side of the radiator, which heats the incoming air flow and prevents cold draughts along the floor.
- The arrangement is designed so that the incoming air flow is delivered at high velocity and is angled upwards behind the radiator.
- A high velocity is important in order to prevent the cold air in wintertime "dropping" down below the radiator due to the high density of the air. If this should happen it results in cold draughts along the floor. Another important effect achieved by a high velocity delivered air flow is that the air flow then also expels the indoor air, that is to say it entrains the indoor air in proximity to the lower parts of the radiator. This means that warm indoor air mixes effectively with the cold outside air, which means that the temperature of the mixed air flow increases. This effect is particularly important in autumn and in spring when the temperature of the outside air may be low whilst the heating system is not in operation. During the heating period the air flow is also heated by the hot radiator. It is also important that the air flow be allowed scope for proper warming by the radiator in that the air flow blows out towards the lower parts of the radiator. It is not effective, for example, to use an air device 230 mm behind a radiator which is 600 mm high. Since the arrangement according to the present invention allows the air flow to blow out against the lower parts of the radiator, this provides efficient heating of the outside air, since the air flow is forced to flow such a long distance along the radiator.
- According to a preferred embodiment the flexible duct is a substantially airtight fabric and the second part is suspended behind the radiator in the duct and the duct is suspended behind the radiator in the first part. This solves the problem of fitting an air device behind a radiator without having to remove either the radiator or the window-sill. This affords the advantage that the arrangement can be applied without the need to remove the radiator and the weight of the second part keeps the duct taut and in place.

- The invention will now be described in more detail with reference to the schematic drawings which show an embodiment of the present invention. The arrangement according to the present invention comprises three parts assembled into one unit. The arrangement has a depth, also known to the person skilled in the art as the overall depth, of approximately 17 mm, which corresponds to the minimum dimension encountered between radiator and wall. Its height behind the radiator is adjusted so that the largest possible proportion of the radiator is utilised.
- The first part 1 is referred to as a filter box. Fitted in this is a
replaceable filter 10. When changing filters afilter hatch 6, which may be insulated against condensation, is undone, providing access to the filter. When the filter is removed there is a free passage out to the incoming air duct (in the façade wall). This can then easily be cleaned from indoors. A flexible and substantiallyairtight duct 3 is arranged in the lower edge of the filter box. The term substantially airtight means that the greater part of the air flow passes through the duct. The material for the duct can also be selected so that a minor leakage is permitted, which cannot be deemed to affect the functioning of the duct, however. It is intended that the duct material be selected according to requirements, a flexible material being chosen, that is to say a material such as textile, rubber, rubberised fabric, film, fibrous material. - Arranged at the other end of the
flexible duct 3 is asecond part 2, which may also be known to the person skilled in the art as an expeller. The term expeller relates to a nozzle for blowing the air flow out and directing it, and which can be varied according to requirements. Other variants with equivalent characteristics may be used, however. Thesecond part 2 is designed so that the incoming air flow is delivered at high velocity and is angled upwards behind aradiator 5. - A high velocity is important in order to prevent the cold air in wintertime "dropping" down below the radiator 5 (due to the high density of the air). If this should happen it results in cold draughts along the floor. Another important effect achieved by a high velocity of the delivered air flow is that the air flow then also expels the indoor air. This means that warm indoor air mixes effectively with the cold outside air, which means that the temperature of the mixed air flow increases. This effect is particularly important in autumn and in spring when the temperature of the outside air may be low whilst the heating system is not in operation. During the heating period the air flow is naturally also heated by the
hot radiator 5 - The design of the air device, with the
duct 3 of flexible material, makes it possible to adjust the height of the air device so that the outside air is at all times delivered to the lower edge of theradiator 5. In order to utilise the space behind theradiator 5 and to obtain the maximum possible effect, theduct 3 has an elongated cross-section. - Using an air device which is half the height of the
radiator 5 behind which it is located, for example, is not effective. It is better if the outdoor air delivered is at all times delivered down behind theradiator 5 and is heated by theradiator 5 over the longest possible distance. This affords effective heating of the outside air since the air flow is forced to flow further along theradiator 5. - In order to facilitate cleaning of the
duct 3, it is secured in such a way that it can readily be removed, see below for a more detailed description of the removal of theduct 3. Theduct 3 can be cleaned or replaced with a new one. In addition, the filter box 1 and thesecond part 2 can also be cleaned, for example, in a dishwasher, manually or by any other suitable method, so as to thereby clean the affected parts. - The first part 1, the filter box, comprises a box, the front side of which has an opening 7 in order to permit installation and changing of filters. The filter box 1 further more has a rear side which bears against a house wall which is provided with holes for the incoming air. In order to allow the incoming air to flow into the filter box 1 there is also at least one
opening 8 on the rear side of the box against the house wall. In the rear wall of the filter box 1 there areholes 13 for fitting the filter box 1 to the house wall. There are preferably just twoholes 13 with corresponding notches in the filter box 1 in order to allow screws to be fixed in the house wall, on to which the filter box 1 is then firmly hooked and slipped down so that the screws are carried along the notches, the screws then be properly tightened. Between the rear side of the filter box 1 and the house wall there is a sealing strip (not shown) for sealing between the filter box 1 and the house wall. The sealing strip prevents air from percolating out between the filter box 1 and the house wall. Theopening 8 at the rear of the filter box 1 is somewhat over-dimensioned, theopening 8 being extra wide and high, in order to make the filter box 1 easier to install and adjust to the holes made in the house wall. It is possible to open up a number of holes in the house wall and the holes are not restricted to a particular size. However, the holes must be accommodated within the boundary of therear opening 8 of the filter box. - This also allows any existing openings left by slit vents to be used, these usually being wide and narrow (low). The
wide opening 8 on the rear side of the filter box 1, however, allows the filter box 1 also to be used for these openings. - The
filter hatch 6 for closing the front opening 7 of the filter box 1 is arranged at the front of the filter box 1. This means that the incoming air coming from the holes in the house wall is guided downwards towards theduct 3 and on to thesecond part 2. Thefilter hatch 6 also allows thefilter 10 to be replaced or cleaned, as required. - The filter box 1 is furthermore open at the bottom, where the
duct 3 is intended to be fixed. The opening at the bottom allows the incoming air to flow towards theduct 3 and onwards to thesecond part 2, which is fixed to the other end of theduct 3. Where the filter box 1 opens to theduct 3, two of the longitudinal sides of the filter box 1 are preferably angled towards the front and rear side respectively of the filter box 1, which allows theduct 3 to be fixed to the filter box 1. Two grooves with rails reinforcing the grooves are correspondingly formed on theduct 3. In order to secure theduct 3, the reinforced grooves of theduct 3 are bent backwards and pressed into the hooks formed by the backwardangled parts 12 of the filter box 1. - The first opening of the
duct 3 is fixed to the lower opening of the filter box 1 and thesecond part 2 is accordingly fixed to the second opening of theduct 3 in the same way, using the same technique with which theduct 3 and the filter box 1 are connected to one another. It is possible to vary the height of theduct 3, that is to say the distance between the filter box 1 and thesecond part 2, so that the overall height of the filter device according to the present invention is adjusted according to the varying radiator heights encountered. Certain heights ofradiators 5 are more common than others, however, which means that a standard height of air device will suffice for most radiator heights. For special designs ofradiators 5 it is consequently very easy to adapt the air device to the height of theradiator 5 by using a suitable height for theduct 3. - In order to dismantle the
duct 3, that is to say to release theduct 3 from the filter box 1 and thesecond part 2, the ends of theduct 3 are respectively pulled or pushed towards the filter box or thesecond part 2. This causes the reinforced grooves of theduct 3 to be released from the hooks formed by the backwards angledpart 12 of the filter box 1 and the backwardangled part 9 of thesecond part 2. When the grooves are released from the backwardangled parts duct 3 free from the filter box 1 and thesecond part 2. - The
second part 2 has anopening 11 to theduct 3 and said backwardangled parts 9 for fixing thesecond part 2 to theduct 3. Thesecond part 2 also comprises at least oneopening 4, an expeller, which is angled in order to allow the air flow from theduct 3 to be discharged towards theradiator 5 away from the floor and upwards. In this way the air flow is guided for a longer distance along theradiator 5, so that it is heated to the desired temperature and assumes a reduced velocity when the air flow leaves the radiator upwards and out into the room in which the air device and theradiator 5 are located. Thesecond part 2 preferably comprises two ormore openings 4, so as to be able to guide the air flow between the panels of radiators having double panels or triple panels. It is also possible to use collapsible expellers so as to be able to adjust the angles at which the air flow is guided and also to allow anopening 4 to be completely closed. - If the
radiator 5 is not to be removed: - 1. Make one or more holes (for example 1x85, 1x105, 2x55 or 3x55 mm) in the façade wall above the
radiator 5. There is no need to specially shape the holes. They may be of any suitable format, for example angular or circular. - 2. Fit a façade duct (in the façade wall) and façade grille.
- 3. The device according to the present invention is inserted down behind the radiator 5 (start with the part comprising the expeller). The weight of the
