Abstract
Above a window there is arranged a ventilation lock (2) which permits air to enter into the room, but prevents noise from penetrating. A roller-blind casing (3) is located in front of the ventilation lock, the intermediate wall (6) exhibiting, laterally, an opening (9) for the passage of air, and an air-outlet opening (12) into the building interior being arranged on the wall (7), of the ventilation lock, which is laid against the room, to be precise on the side located opposite the opening (9). All the walls (6, 7) as well as the lateral closing-off means (4) with respect to the window reveal, consist of sound-absorbing material. In the intermediate wall (6), a suction blower (8) may be arranged in the opening (9). The arrangement is preferably suitable for windows glazed with toughened safety glass. <IMAGE>
Description
(54) A SOUND-ABSORBING VENTILATION INSTALLATION FOR OPENINGS IN
BUILDINGS
(71) We, J. EBERSPACHER, a German Company, of Eberspacherstrasse 24, 7300 Esslingen/Neckar, Federal Republic of
Germany, do hereby declare the invention for which we pray that a patent may be granted to us, and the method bv which it is to be performed, to be particularly described in and by the following statement:
The present invention relates to a soundabsorbing ventilating (assembly) for openings in buildings.
To an increasing extent, there is a need to protect rooms in buildings against penetrating noise. Single glazed windows are inadequate, especially at night time, since for reasons of ventilation it is desirable not to close the window tightly. Sound-proofed ventilation grilles in conjunction with windows having single or multiple pane glazing have therefore been fitted, in order to obtain adequate ventilation in spite of the window being closed.
It has, however, been shown that ventilation grilles of this type are insufficient to deaden the sound which occurs nowadays to such an extent that undisturbed sleep is possible. Moreover the use of a roller blind to assist in deadening the sound in these known arrangements, has been found to be impossible due to lack of space.
An attempt has been made to provide sound-proofing by means of a soundscreening roller blind with adjustable ventilation slits, each of the strips of which are constructed so as to be sound-absorbing on one side. Thus roller blinds have been used having two spaced steel plates provided with a staggered arrangement of ventilation slits.
The sound-absorbing sides of the roller blind strips in such an arrangement are directed towards the hollow space between the steel plates (German Auslegeschrift 1 282 284). Such arrangements, however, have the disadvantage that they occupy an exceptionally large overall space. Hence they have not been employed in practice.
An object of the invention therefore is to provide an arrangement for sound insulation in buildings which is constructionally simple yet produces adequate sound insulation and ventilation even with single-glazed windows. The arrangement must also be suitable for use in existing buildings.
According to the invention there is provided a sound-absorbing ventilating (assembly) for an opening in a building comprising a window, an elongate casing on the window housing a roller blind for the window, an air inflow aperture in the casing for admitting outside air thereto, and a ventilation duct adjacent the casing and extending longitudinally thereof, said duct having an air inlet open to the casing, and an air outlet for delivering air to the building offset longitudinally of the duct with respect to said air inlet so that air entering said inlet flows longitudinally of the duct to exit from said air outlet.
Because of the relative arrangement of the ventilation duct and the casing, a series connection relating to the passage of air through the installation is achieved. Thus adequate ventilation of the inside of the building is possible even with the window closed, both when the roller blind is lowered and raised. In this way optimal acoustic protection is provided on the lateral surfaces of an opening in a building, in which the arrangement is employed, in conjunction with provided edge insulation.
When the roller blind is lowered during the evening or at night, especially good sound insulation is produced. Valves of Rw 2 45 (d) B have been measured, where the
K valve has also been reduced to below 1 kcal/h . m2K. As a result of the improvement of transverse insulation of the duct by the adjacent roller blind casing, it is possible to use materials which are better from the point of view of manufacturing technology for the ventilation duct. Preferably acoustically permeable foil is used for edge insulation composed of polyethylene foil.
A perforated plate may be located in the opening between the ventilation duct and the roller blind casing.
The aperture for passage of the roller blind to and from the casing may be used as the air inflow aperture for outside air passing to the ventilation duct. As a result, an adequate quantity of air can be sucked in without additional inflow apertures having to be provided in the roller blind casing.
Thus air enters the roller blind casing over its entire length, and from there is sucked in without additional inflow apertures having to be provided in the roller blind casing.
Thus air enters the roller blind casing over its entire length, and from there is sucked into the ventilation duct through the air inlet between the casing and the duct. An intake blower may be located in the air inlet between the casing and the duct, the outflow aperture for the air from the duct to the inside of the building being offset longitudinally with respect to the air inlet so that sucked-in air always flows through the ventilation duct in a longitudinal direction.
The roller blind casing is constructed as a part of the ventilation duct, but may be a separate unit. An integral arrangement of duct and casing has proved advantageous with installations in new buildings or reconstructed buildings, where the windows are completely replaced. It produces simplification of manufacturing technology by omitting one wall between the ventilation duct and the roller blind casing, since only one dividing wall is necessary as compared with a separate construction.
The clearance between the window and the roller blind may be at least 10 cm, and preferably 12-14 cm, when the roller blind is lowered. It has been shown that optimal sound insulation can be achieved with these dimensions.
An embodiment of the invention will now be described by way of example with reference to the accompanying drawings wherein:
Figure 1 shows a longitudinal section of a sound-absorbing ventilation assembly according to an embodiment of the invention; and
Figure 2 shows a sectional view of the assembly of Figure 1.
The assembly shown in Figure 1 is shown mounted in an opening in the wall 1 of a building.
The assembly comprises a window 10 for the opening surmounted by a ventilation duct 2 and a casing 3 housing a roller blind for the window 10. The duct 2 and casing 3 are arranged to lie adjacent one another along the top of the window 2.
The longitudinal flow-through ventilation duct 2 is positioned to face the inside of the building and the roller blind case 3 to the exterior of the building. The advantage of the longitudinal flow-through duct 2, is that it does not project too far into the inside of the building, compared with known transverse flow-through ducts.
The opening is provided with edge insulation 4 composed of a sound-absorbing material covered with an acoustically permeable polyethylene foil and a perforated plate.
Thus when mounted in the opening of the wall 1, the insulation 4 is interposed between the duct 2 and casing 3 and the walls of the opening.
The roller blind 5 in its lowered position, provides sound insulation with a clearance of 'a' = 12 cm in front of a window 10.
The ventilation duct 2 is provided with sound-absorbing material 6 and 7 on at least two sides. A built-in intake blower 8 sucks the air occurring at 11 into the casing 3 and through an inflow aperture 9 between the casing 3 and the duct 2, into the ventilation duct 2. The air then flows through the duct 2 in a longitudinal direction and passes through the air outflow aperture 12 in the duct 2 and into the building.
An aperture 13 constituting a passage for the blind to and from the casing 3, provides an air intake aperture so that air can enter longitudinally of the casing 3 and thence to the ventilation duct 2. Fastening of the casing 3 together with the ventilation duct 2, to the wall 1 is by means of retaining elements 14.
