Abstract (en)

[origin: EP0255039A2] A cavity floor comprises the underfloor (10), covered by a heat insulating layer (11), on which the upper floor (12) rests with supporting feet (13). Provided in the heat insulating layer (11) are channels (17), in which there are hot air ducts (18). The hot air fed in flows through the hot air duct (18) into a distributing space and from there into the cavity floor (16), which is arranged on a different level than the hot air ducts (18). The cross-section of the hot air ducts (18) is independent of the height of the supporting feet (13). The supporting feet (13) can be of a small height, thereby increasing the air velocity in the floor cavity (16) and improving heat transfer. <IMAGE>
