    Ventilation assembly for a building, as well as method for operating such a ventilation assembly
    The invention relates to a ventilation assembly for a building, comprising a frame as well as a closable main ventilation device connected to the frame with a grid and a valve means, wherein the maximum flow rate of one of the ventilation devices differs from the maximum flow rate of another ventilation -design.
    A ventilation assembly with a vent hatch is known. The known ventilation assembly generally comprises a grille, behind which this vent hatch is placed, which is movable between an open position and a closed position. In a relatively warm period, such as the summer period, this trap door is put in the open position at night to allow relatively cool air to enter the building. This is also called night ventilation.
    A drawback of such a ventilation assembly is that it is relatively difficult to control the flow through the air supply part with this vent section, since only when the vent section is opened to a relatively small extent does the flow change to a relatively large extent. In addition, even with a slight opening of the vent, the flow rate is usually too high for ventilation during the day, so that a relatively large amount of warm air enters the building from outside, which cancels out the effect of night ventilation. In addition, there can be a similarly large amount of cold air in the winter that enters the building at night and then needs to be heated.
    WO 2008/068774 discloses a ventilation assembly in the form of an air-conditioning unit with a closable main ventilation device that ensures an actively cooled air flow. This main ventilation device comprises a grille and a tiltable valve, which enables the cooled air flow through the grille in an open position and covers the grille in a closed state to block the cooled air flow. An auxiliary ventilation device in the form of a slide is arranged in said valve so that, when the valve covers the grille in the closed position, a relatively small cooled air flow through that valve is nevertheless possible.
    A disadvantage of the ventilation assembly of WO 2008/068774 is that the auxiliary ventilation device and the main ventilation device cannot function independently of each other. A related drawback is that the flow rate cannot, as a result, be fine-tuned.
    It is an object of the invention to provide a ventilation assembly in which the main ventilation device and the auxiliary ventilation device can function substantially independently of each other. It is a further object of the invention to provide a ventilation assembly that allows finer control of the flow.
    To this end, the ventilation assembly according to the invention is characterized in that at least one closable auxiliary ventilation device is directly connected to an edge of the frame.
    Because at least one closable auxiliary ventilation device is directly connected to an edge of the frame, the auxiliary ventilation device is not dependent on the main ventilation device for its functioning (in particular the position of the valve of the main ventilation device). A finer regulation of the flow rate through the ventilation assembly can hereby also be achieved.
    A first embodiment relates to a ventilation assembly in which the auxiliary ventilation device is provided adjacent to and outside the outside circumference of the grille, and preferably outside the outside circumference of the grille, with the main ventilation device. This results in an assembly in which the auxiliary ventilation device and the main ventilation device are conveniently combined.
    A further embodiment relates to a ventilation assembly in which the auxiliary ventilation device at least partially overlaps the grid of the main ventilation device. Due to this overlap, a more uniform view of the ventilation assembly can be obtained and the overall dimensions can remain limited.
    A still further embodiment relates to a ventilation assembly in which the valve means is located on an edge of the outer circumference of the grille of the main ventilation device and the auxiliary ventilation device is located on an opposite edge of that grille. This way relatively optimal use is made of the available space.
    An advantageous embodiment relates to a ventilation assembly in which the valve means comprises at least one valve or hatch, and preferably a plurality of adjacent valves. The position of a valve, or valves, or a hatch and the associated flow rate is relatively easy to adjust. The valve means can be arranged both hinged and sliding.
    A still further embodiment relates to a ventilation assembly in which an auxiliary ventilation device comprises in a known manner a housing through which a ventilation passage extends, as well as a valve body which is accommodated in the housing and which is rotatable between an open and a closed state. The rotatable valve body with the said ventilation passage ensures a fine control of the flow through the auxiliary ventilation device.
    A still further embodiment relates to a ventilation assembly in which the maximum flow rate of the main ventilation device is greater than the sum of the maximum flow rate of all auxiliary ventilation devices. Thus it is achieved that a coarse flow control is made possible with the main ventilation device, while a fine flow control is achieved with the auxiliary ventilation devices.
    A still further embodiment relates to a ventilation assembly in which the grille of the main ventilation device comprises mutually parallel slats between which ventilation passages are situated. Such a schedule can be burglar-proof.
    A still further embodiment relates to a ventilation assembly in which the slats are mutually connected by support profiles, and wherein an auxiliary ventilation device is attached to the support profiles. The support profiles act as a relatively easy attachment point for the auxiliary ventilation device.
    A still further embodiment relates to a ventilation assembly in which thermal insulation is arranged between the auxiliary ventilation device and the valve means on the one hand and the frame on the other hand. The thermal insulation provides a thermal interruption, so that the auxiliary ventilation device and the valve means are prevented from assuming the temperature of the frame and thereby would adversely affect the climate of the space behind.
    A still further embodiment relates to a ventilation assembly, wherein a throttle element is arranged upstream of the auxiliary ventilation device. With an increasing air pressure on the outside of the ventilation assembly, the throttle element closes off the auxiliary ventilation device, so that the air flow through the auxiliary ventilation device is reduced or prevented.
    The invention furthermore relates to a method for operating a ventilation assembly according to any one of the preceding claims, comprising the steps of: - determining a day and night cycle, keeping the open part of the cycle part coincident with the night main ventilation device and keeping an auxiliary ventilation device closed, keeping the main ventilation device closed during the day-end cycle part and keeping an auxiliary ventilation device open.
    Embodiments of a ventilation assembly according to the invention are further elucidated with reference to the accompanying figures. It shows:
    FIG. 1 a sectional view of a ventilation assembly according to the invention, with an auxiliary ventilation device with a rotatable valve body, the ventilation assembly being placed in a frame,
    FIG. 2 shows the ventilation assembly of FIG. 1 with an auxiliary ventilation device with two rotatable valve bodies,
    FIG. 3 shows the ventilation assembly of FIG.
    1 with an auxiliary ventilation device with removable profiles, and
    FIG. 4 shows the ventilation assembly of FIG. 2, wherein the ventilation assembly is arranged in a facade of a building.
    FIG. 1 is a sectional view of a ventilation assembly 1 according to the invention with an auxiliary ventilation device 4 with a rotatable valve body 13, which ventilation assembly 1 is placed in a frame 18. The outside of the facade in which the ventilation assembly 1 is placed is located on the left-hand side of the ventilation assembly 1 in Fig. 1. The inside of the building is located on the right-hand side of the ventilation assembly 1. In this exemplary embodiment, the ventilation assembly 1 comprises a grid 2, for example a burglar-resistant grid made of slats 6 and support profiles 26, and with a supporting frame 8 as a frame. On the inside of the grille 2 a main ventilation device 3 with a vent flap 15 is arranged as a valve means.
    For ventilation, outside air is drawn in by the auxiliary ventilation device 4 or the main ventilation device 3 by means of a mechanical ventilation unit (not shown) placed in or on the building. This mechanical ventilation unit can, for example, be CO2-controlled and be in communication connection with the auxiliary ventilation device 4 and main ventilation device 3.
    In this exemplary embodiment, the auxiliary ventilation device 4 is mounted between the grate 2 and an upper, horizontal profile of the frame 18 on the support profiles 26. The grate 2 is thereby provided on an upper side with a fitting profile 17 which is arranged in a receiving slot 23 on the underside of the auxiliary ventilation device 4. The auxiliary ventilation device 4 is provided at the top with a fitting profile 24 which is placed in the receiving slot 19 in the frame 18.
    The grille 2 has a number of slats 6. On the outside of the auxiliary ventilation device 4, upstream of the auxiliary ventilation device 4, a throttle element or self-regulating valve 7 is arranged. With an increasing air pressure on the outside of the ventilation assembly 1, the throttle element 7 closes off the opening 22 located upstream of the auxiliary ventilation device 4, so that the flow through the auxiliary ventilation device 4 is reduced. The throttle element or the self-regulating valve 7 can advantageously be of the type as described in the patent NL
    1,027,908.
    In this exemplary embodiment, the auxiliary ventilation device 4 has a housing 12 in which a rotatable valve body 13 is located. This rotatable valve body 13 is rotatable about an axis of rotation, whereby the rotatable valve body 13 can be transferred between a closed position and a partially or fully opened position by rotation. On the inside, the housing 12 of the auxiliary ventilation device 4 is provided with a removable insect screen for retaining insects. The auxiliary ventilation device 4 can be operated manually, such as by means of a cord connected to the rotatable valve body 13, or motorically, for example with the aid of a servomotor. Such a Servo motor can advantageously be controlled with the help of the CO2 control.
    Near a lower part of the grid 2, the slit flap 15 is mounted tiltably via a hinge 14. The slit flap 15 is movable between a closed position, wherein the slit flap 15 is oriented substantially vertically, covers parallel to the grille 2 and an air supply opening 16, and an open position, in which the slit flap 15 is tilted relative to the frame 8. The slit flap 15 is provided with thermal insulation 27. On the inside of the grid 2, mosquito netting (not shown) or a similar mesh can advantageously be tensioned.
    In a relatively warm period, for example in the summer period, the slit flap 15 can be put in the open position at night, so that relatively cool night air is admitted into the building via the air supply opening 16. The slit flap 15 has dimensions such that a relatively large flow rate can be achieved. In the exemplary embodiment of Fig. 1, the height of the slit flap 15 is approximately equal to the height of the frame 8. Due to the relatively large flow rate, the building is sufficiently cooled during the night, so that a pleasant temperature in the building can be achieved during the day. The mosquito netting meshed in front of grid 2 ensures that no mosquitoes or other vermin can enter the building during the night. By making the grid 2 burglar-resistant, it is possible to prevent unwanted people from gaining unwanted access to the building at night.
    During the relatively warm period, the vent hatch 15 is placed in the closed position during the day, so that relatively warm air cannot enter the building via the opening 16 that can be closed by the hatch hatch 15. The building, more specifically the relevant space, is now only ventilated by means of the auxiliary ventilation device 4, with which only a relatively small and finely adjustable flow rate can be achieved, compared to the flow rate that can be achieved through the vent 15 in the open position. However, this relatively small flow rate is sufficient to guarantee good air quality during the day, while relatively little warm air enters the building from outside.
    FIG. 2 shows the ventilation assembly 1 of FIG. 1 with an auxiliary ventilation device 4 'with two rotatable valve bodies 13. In this exemplary embodiment, the auxiliary ventilation device 4' is provided with two rotatable valve bodies 13. The auxiliary ventilation device 4 * in this exemplary embodiment is arranged on the inside of the grid 2, or behind the grid 2. On the inside, the auxiliary ventilation device 4 'is provided with two removable insect grilles for retaining insects. Thermal insulation 5 is provided on the supporting frame 8. The thermal insulation 5 isolates the auxiliary ventilation device 47 and a main ventilation device 3 comprising a vent flap 15 of the supporting frame 8. The insulation 5 thus prevents the flue vent 15 and the auxiliary ventilation device 4 from being thermally conductive. with the supporting frame 8. Two throttle elements 7 are each suspended from a slat 6. Near a lower part of the frame 8 is arranged a lower thermal insulation part, on which the slit flap 15 is mounted for tilting via a hinge 14. This slit flap 15 is also provided with thermal insulation 27.
    FIG. 3 shows the ventilation assembly 1 of FIG. 2 with an auxiliary ventilation device 4 '' with removable profiles 10. The outlet hatch 15 has now been replaced by three smaller outlet valves 9. Another number of outlet valves 9 is also possible. Due to the use of the smaller vent valves 9, the flow through the opening 16 can be controlled more precisely. Of course, even smaller vent valves 9 can be used, depending on the wishes of the user. The position of an individual drain valve 9 can, if desired, be adjusted independently of the other drain valves 9.
    In this example, the auxiliary ventilation device 4 '' comprises two profiles 11 placed one above the other, with removable profiles 10 accommodated therein, which can for instance be provided with insect gauze to keep insects and other vermin out. Of course, the number of profiles 11 placed above one another can be varied, this on the basis of the desired flow rate through the auxiliary ventilation device. The auxiliary ventilation device 4 '' is arranged between an upper thermal insulation section 5 and an intermediate thermal insulation section, so that the auxiliary ventilation device 4 '' is thermally disconnected from the frame 8 with the grid 2. The auxiliary ventilation device 4 '' can be be operated manually as motorized. The same also applies to the main ventilation device 3 '. In the case of manual operation, the auxiliary ventilation device 4 '' can for instance advantageously be placed at a height of 1.8 m from a floor present in the relevant room of the building in order to increase the user comfort. The auxiliary ventilation device 4 '' can also be advantageously connected to the frame 8 by means of a snap connection, so that if desired other types of basic ventilation units 4 '' can be clicked in, such as for example an auxiliary ventilation device 4 '' with rotatable valve bodies such as shown in FIG. 2.
    FIG. 4 shows the ventilation assembly 1 of fig. 2, wherein the ventilation assembly 1 is arranged in a facade 20 of a building. A leg 17a of the fitting profile 17 thereby partially overlaps with the outside of the facade 20 and bears on it. A uniform appearance of the ventilation assembly 1 is thus obtained on the outside. A leg 17b of the fitting profile 17 extends close to the facade 20.
    It will further be understood that the above description is included to illustrate the operation of some exemplary embodiments of the invention, and not to limit the scope of the invention. Starting from the above explanation, many variations will be evident to those skilled in the art that fall within the spirit and scope of the present invention.
