12. Dyse (16) ifølge krav 11, hvor længdeaksen af den indre væg (72) befinder sig vertikalt over længdeaksen af den ydre væg (70).
13. Dyse (16) ifølge et hvilket som helst af de foregående krav, hvor den mindst ene luftudgang (18) omfatter en enkelt luftudgang.
14. Ventilatorenhed (10), der omfatter et vingehjul (40), en motor (44), til at dreje vingehjulet (40) for at generere en luftstrøm, og en dyse (16) ifølge et hvilket som helst af de foregående krav til modtagelse af luftstrømmen.
