Device for building ventilation

Abstract

The present invention relates to a device for building ventilation, having heat recapturing, wherein the heat of the room air that is fed outside is recaptured, and cold outside air being fed inside can be preheated by means of the recaptured heat.

         4 . The ventilation system according to  claim 1 ,
 wherein the vent openings and/or the aeration openings can be closed.   
     
     
         5 . The ventilation system according to  claim 1 ,
 Wherein pumping elements are provided for supporting the circulation of the heat transfer medium.   
     
     
         6 . The ventilation system according to  claim 5 ,
 wherein the pumping elements are electrical pumping elements.   
     
     
         7 . The ventilation system according to  claim 6 ,
 wherein the electrical pumping elements are driven by means of solar cells.   
     
     
         8 . The ventilation system according to  claim 1 ,
 wherein the building element is a window casement, a window frame, a door panel, a door frame, or a wall or roofing element.   
     
     
         9 . The ventilation system according to
 wherein the first region is accommodated in the upper part and the second region in the lower part of the building element.   
     
     
         10 . The ventilation system according to  claim 1 ,
 wherein at least the outer vent openings and the outer aeration openings are closed toward the outside by means of a screen.   
     
     
         11 . The ventilation system according to  claim 1 ,
 wherein at least the pipeline that is found upstream to the first heat exchanger is heat-insulated, and a check valve is provided downstream to the second heat exchanger and/or a second check valve is provided downstream to the first heat exchanger.   
     
     
         12 . The ventilation system according to  claim 11 ,
 wherein the vent openings and/or the aeration openings can be closed.   
     
     
         13 . The ventilation system according to  claim 12 ,
 wherein pumping elements are provided for supporting the circulation of the heat transfer medium.   
     
     
         14 . The ventilation system according to  claim 11 ,
 wherein pumping elements are provided for supporting the circulation of the heat transfer medium.   
     
     
         15 . The ventilation system according to  claim 13 ,
