Method and device for air-conditioning a room

A device comprising at least one heat sink having at least one boundary surface facing a room, said boundary surface configured to have a temperature being lower than a thermal load inside said room, wherein at least one panel element is arranged between the boundary surface and the room, said panel element being at least partially permeable to heat radiation, wherein

• the panel element is spaced apart from the boundary surface, thereby forming a gap between the panel element and the boundary surface and the at least one panel element and the heat sink are surrounded by an edge compound, which is configured to seal the gap against the surroundings, wherein said device further comprises at least one dehumidifying apparatus being configured to expel water from the gap between the panel element and the boundary surface, wherein the boundary surface is at least partially covered with a non-woven fabric, and wherein the non-woven fabric extends beyond the edge compound to the rear side of a heat insulation arranged adjacent to said heat sink and on the opposite side of said boundary surface facing the room.
