Abstract

The present invention relates to a ventilation device for ventilation of a building with a double-window construction with an air space, wherein the device communicates with the air space and has at least a first throttle, a second throttle, a third throttle, ad a fourth throttle, wherein the first and the second throttles are able to selectively cut off the passage of air from the air space and into a first and a second chamber, respectively, of the device; wherein the third throttle is able to selectively cut off the passage of air from the first chamber and into the building; and wherein the fourth throttle is able to selectively cut off the passage of air between the open and the first and the second chamber; temperature-sensitive actuators for actuation of the throttles, whereby the air from the space will, in case of increasing temperature within a first low range of temperatures of the air in the air space, to an increasing extent be conveyed into the device via the first and the second throttle and on into the building; and temperature-sensitive actuators for actuation of the throttles, whereby the air will, in case of increasing temperatures within a second range of temperatures of the air in the air space 5/the flow passage 17, above said first temperature range, be conveyed from the space and out into the open by closure of the second throttle and the third throttle and opening of the fourth throttle, simultaneously with air from the open being allowed to flow into the second chamber via the fourth throttle. Hereby a ventilation device is accomplished, whereby, in particular circumstances, it is possible to regulate the amount of air and the temperature in the air space of the window and hence of the room in the building, as it is hereby ensured that a certain amount of air is supplied to the room of the building.

Claims

1. A ventilation device (20) for ventilation of a building with a double-window construction having between the window glass panes an air space and with an air intake (15) and the lower frame element (3) of the double window, wherein the device is in communication with the air space, characterized in that the device has at least a first throttle, a second throttle, a third throttle;

and a fourth throttle,

wherein the first and the second throttles are able to selectively cut off the passage of air from the air space and into a first and a second chamber, respectively, of the device, said second chamber being in communication with the building interior;

wherein the third throttle is able to selectively cut off the passage of air from the first chamber and into the building; and

wherein the fourth throttle is able to selectively cut off the passage of air between the open and the first and the second chamber; and

temperature-sensitive actuators for actuation of a second group of throttles, whereby air from the air space will, in case of increasing temperatures of the air within the air space within a first low range of temperatures of the air in the air space, be allowed to flow into the device and on into the building via the first and the second throttle; and

temperature-sensitive actuators for actuating a second group of throttles, whereby the air will, in case of increasing temperatures with in a second range of

temperatures of the air in the air space or close to the fourth throttle above said first

temperature range, be allowed to flow from the space and out into the open by

closure of the second throttle and the third throttle and opening of the fourth throttle,

simultaneously with air from the open being allowed to flow into the second chamber

via the fourth throttle and into the building.

2. A device according to claim 1, characterized in that a first actuator is configured for actuating the first and the second throttle:

and that a second actuator is configured for actuating the fourth throttle.

3. A device according to claim 1, characterized in that air within a third range of temperatures within the air space, said third range being between the first range and the second range, by partial opening of the fourth throttle, can be allowed to flow between the open and the building via the first and the second chamber, simultaneously with air being allowed to flow from the air space and into the building via the first and the second -chamber,

whereby the second activator is caused to actuate the second and the third throttle near the upper limit of the third range, said to throttles being closed in case of increasing temperatures.

4. A device according to claim 1, characterised in that the device comprises a separating wall (26) configured centrally in the device (20) between two adjoining passages (30) in such a manner that two separate chambers (36,37) are provided.

5. A device according claim 1, characterized in that the actuators (41, 42) are self-operating thermohydraulic actuators (41, 42) that contain a liquid with a temperature expansion coefficient that determines the traveling of the throttles (31, 32, 33, 34).

6. A device according to claim 1, characterized in that the first actuator (41) is configured in the first chamber (36).

7. A device according to claim 1, characterized in that the second actuator (42) is configured in a position in front of the ventilation device (20), air intended for traveling through the fourth throttle enclosing the second actuator (42).

8. A method of ventilating a room in a building by use of a ventilation device which is in communication with the air space between the window glass panes in a double-window construction having an air intake (15) at the bottom frame element (3) of the double window, said device having at least a first throttle (31), a second throttle (32), a third throttle (33), and a fourth throttle (34);

wherein the first and the second throttles are able to selectively cut off the passage of air from the air space and into a first and a second chamber, respectively, of the device (20), said second chamber being in communication with the building interior;

wherein the third throttle is able to selectively cut off the passage of air from the first chamber and into the room of the building; and

wherein the fourth throttle is able to selectively cut off the passage of air between the open and the first and the second chamber;

whereby air from the space will, in case of increasing temperatures within a first low range of temperatures for the air within the air space, to an increasing extent be allowed to flow into the device and on into the building via the first and the second throttle; and

whereby the air will, in case of increasing temperatures within a second range of temperatures of the air in the air space or close to the fourth throttle above said first temperature range, be allowed to flow from the space and out into the open by closure of the second throttle and the third throttle and opening of the fourth throttle, simultaneously with air from the open being allowed to flow into the second chamber via the fourth throttle.

9. A method according to claim 8, characterized in that air within a third range of the temperature in the air space, said third range being between the first range and the second range, is by partial opening of the fourth throttle allowed to flow between the air space and into the building via the first and the second chamber, simultaneously with air being allowed to flow from the air space and into the building via the first and the second chambers.

10. A method according to claim 8, characterized in that the actuators are self-operating thermohydraulic actuators (41, 42) that contain a liquid having a temperature expansion coefficient that determines the traveling of the throttles.

11. A method according to claim 8, characterized in that the second actuator (42) is configured with traveling, by which the throttles are actuated, and wherein, during the first part of its traveling, the actuator is configured for closing the first and the second throttles, and, during the last parts of its traveling, it is configured for opening the fourth throttle.

12. A device according to claim 8, characterized in that the device is configured as an elongate box-shaped unit for being incorporated in the upper frame element or upper frame of the double window.
