Abstract
In order to cool a room, a cooling element fitted in the ceiling region is cooled to below the freezing point, preferably to about -40.degree. C., during the cooling phases so that condensate forming thereon freezes immediately. During regeneration phases when the room is not in use, the cooling element is defrosted and the melted condensate is caught in a condensate tray beneath the cooling element and drained via a discharge. The great temperature difference between the room to be cooled and the cooling element also makes it possible to obtain a strong cooling effect with a small cooling element, especially by indirect radiation exchange between the room and the cooling element via an intermediate ceiling. The air in the room is also dehumidified since water vapor is deposited on and bonded to the cooling element in the form of ice. Moreover, the cooling element itself is supported by a stand upon a floor, and detachable from the floor so that the cooling element is capable of being relocated to different locations. In addition, the cooling element includes an upwardly facing cooling surface, a downwardly sloping boundary strip, and a condensate tray.
