Abstract:
1. A ventilation device for ventilation of a building having an interior and an exterior comprising: a double-window, said double window comprising at least two window glass panes and an air space, wherein said air space is between said window glass panes; a first throttle; a second throttle; a third throttle; a fourth throttle; a first actuator is configured for actuating the first throttle, and a second actuator is configured for actuating the second throttle, the third throttle and the fourth throttle; a first chamber wherein said first chamber is in communication with the building interior and exterior; and a second chamber, wherein said second chamber is in communication with the building interior and exterior; wherein said first throttle selectively controls passage of air from said air space into said first chamber, wherein said second throttle selectively controls passage of air from said air space into said second chamber; wherein said third throttle selectively controls passage of air from said first chamber into said building interior; and wherein said fourth throttle selectively controls passage of air between said building exterior and said first and second chamber, wherein temperature-sensitive actuators automatically control each of said first throttle, second throttle, third throttle, and fourth throttle and wherein dependent upon the temperature, 1/air from said air space will flow into the building interior or 2/air from said air space will flow to the building exterior.
