Since I could no longer use as a vented dryer my dryer after moving, I saw in the Kondensatbox a good solution. The frozen ice in the cup to cool the humid air holds only a good drying cycle from, well half. Through the slits of the box but always occurs from moist air and also reflected in the room to the window pane, door glass and elsewhere probably (not so clearly visible). That's why I have the box covered with a Frottèhandtuch. Well, then it has kept away from the area a bit. But was under the impression it has been going to the drying also a lot longer. You have to watch just that the humid air comes out from the space. The other solution would have been a new condenser, as this is somehow less expensive alternative.
