The invention relates to a roof structure, which is a further developed form of a known principle (so-called yast current roof), in which air is taken from the outside and inside into a space between an airtight exterior roof and a heat-insulating and air-permeable ceiling.

This air, which is usually relatively cold and dry, is compressed or sucked down through the ceiling by means of ventilation fans or the like. In this case, the air flowing through absorbs the heat and moisture that would otherwise have flowed out of the space below, resulting in heat loss and condensation in the roof structure.

The disadvantage of this structure is that the air-permeable ceiling, which usually consists of mineral wool, is destroyed by fire and that the amount of air that can pass through the ceiling is limited by the temperature that air can have as it flows into the living space below. The low heat capacity of the ceiling 2,63281 exacerbates this problem. Therefore, the need for ventilation cannot usually be satisfied by this principle.

The object of the invention is to avoid these disadvantages.

This is achieved by the structure defined in the claims. The invention will now be described in more detail with reference to the figures, in which Figure 1 the ceiling 3 is supported by a load-bearing and fire-protection plate 4, through which air flows. Thus, the structure is protected against fire and can carry loads.

Due to its considerable weight (which is otherwise adapted), the same plate 4 has a relatively high heat capacity, which, due to the flow of air, can be fully utilized for the air conditioning of the rooms below. In summer, for example, cool night air can be blown through the tile, which is thus able to absorb heat during the day from the sun-heated day air.

Due to the reasonable temperature of the roof, it can also act as a coolant by absorbing the heat radiation coming from below. This saves significant amounts of energy that would otherwise be consumed in the air conditioner.

Fig. 2 shows the same principle as Fig. 1, but in addition a heating element 5 is inserted between the insulator 3 and the load-bearing plate 4, through which air flows, e.g. an electrically operated, resistance-heated metal network (duct network, etc.).

With this heating option, the temperature of the air flowing through can be adjusted and thus the amount of air can be increased to such an extent that in certain cases no other ventilation is required in the rooms below. The heating and ventilation problem is thus solved in a reasonable way.

The load-bearing plate 4 (Figures 1 and 2), through which air can flow, has a sound-absorbing effect due to its open structure, whereby good acoustics are achieved approximately as described by the known principle described above.
