Definitions
- the present invention relates to an arrangement for controlling the temperature in buildings comprising at least one intermediate floor structure which separates at least one upper room from at least one lower room and which comprises a concrete slab and, on the underside thereof, a ceiling for said lower room, said floor struc ⁇ ture comprising pipes for a heating medium serving to transfer heat to and from air which is introduced through a gap between the concrete slab and the ceiling and which is then supplied to the lower room via said ceiling.
- Prior art technique comprises heating systems in which a concrete floor structure is charged with heat or cold by means of pipes conducting a heat transfer medium, such as water, and embedded in the floor structure. In these systems, discharge and temperature control is car ⁇ ried out by causing varying amounts of air to flow through air ducts embedded in said floor structure. Since concrete has excellent heat accumulating capacity, such an arrange- ment contributes to an even indoor temperature, at the same time as it is possible to charge the floor structure at periods when energy is inexpensive.
- DE 893,855 discloses a floor structure comprising a concrete slab and, at a distance underneath said slab, a ceiling for a lower room. Pipes conducting a heating me ⁇ dium are laid in the air gap formed between the ceiling and the concrete slab, the intention,being that an air current will flow through the air gap, heat being exchang ⁇ ed between the air and the heating medium, whereupon the air will flow down into the lower room through a large number of small holes in the ceiling.
- a heat-in- sulating layer is disposed in the area below the concrete slab, which means that the heat-accumulating and tempera ⁇ ture-equalising capacity of the concrete slab cannot be utilised.
- Fig. 1 is a schematic cross-sectional view of a build equipped with the arrangement according to the invention; and Fig. 2 is an enlarged part-sectional view of a floor structure forming part of the building in Fig. Detailed description of a preferred embodiment
- Fig. 1 is a cross-sectional view of a multistorey building comprising a base slab 1, a number of interme diate floor structures 2, and a roof-supporting struct 3.
- Each of the floor structures comprises a concrete s 2* and, on the underside thereof, a celling 5 for a ro below.
- a heating medium suitably water, is to flow through pipes 4 embedded In the concrete slab 2' .
- the embedment is carried out in such a mann that the supporting floor structure is first cast in c ventional manner with the requisite reinforcement, re ⁇ Deads, etc.
- the pipes whi for example, may consist of thin and flexible plastic hoses, are laid out on the floor structure, and a thin screed layer of fine concrete or so-called self-levell flooring compound is then made. In actual practice, it preferred that the pipes are thus arranged In the uppe half of the concrete slab.
- Fig. 2 shows the construction of the floor structure more in tail and which illustrates how the floor structure sep rates an upper room 20 from a lower room 21.
- a ceiling for a lower room 21 is disposed underneath the concret slab 2', at a certain distance from the underside ther Thus, an air gap 6 is defined between the ceiling and slab.
- the ceiling may be mounted on studs 7 suspended spacers 8, e.g. metal strips or the like, which are fi to the floor structure.
- studs of the type having open web portions through which the air can flow freely.
- the air intakes to the air gap 6 may suitably consist of a few air supply devices 9 in the face of the building, which suitably should co - prise air filters 10 easily accessible from every floor for cleaning or replacement.
- the ceiling con ⁇ sists of a perforated or otherwise air-permeable board material so that air can be supplied to the room below over a large area. Owing to the ensuing low air speeds, the air supply to the lower room is free from draught.
- Used indoor air is removed by means of air exhaust devices 11 and collected in a ventilation duct 12 common to seve ⁇ ral rooms, and leaves the building through the roof.
- a fan 13 is needed for producing the air flow and is suitably positioned in a space immediately below the roof.
- the system also comprises a heat pump 14 which makes use of heat from a deep well 15, and recovers heat from the exhaust air via a heat exchanger 16 on the roof. Then, the heat from the heat pump is supplied to the medium in the pipes in the floor structure at is ⁇ sue. It should be pointed out that the above description of the heating also, where applicable, concerns the cool ⁇ ing of the building.
- the arrangement shown n the drawings and described above provides a combined and flexible system for venti ⁇ lation, as well as for heating and cooling.
- a further ad ⁇ vantage is that useful spaces are created in the air gap, in which electric lines and communication lines can be run. Since the air gap extends over the entire underside of the floor structure, an insulating layer is formed, such that the room temperatures above and below every floor structure can be adjusted Independently of one an ⁇ other, e.g. by varying the air flow through the gap.
- the system can also be enlarged in various manners, such that separate floor structures and also separate floor struc ⁇ ture portions are provided with separate shunts so that the heat supply can be adapted to the requirements of dif ⁇ ferent parts of the building.
- the drawings also illustrate how a number of heat exchangers 17 are positioned in the air gaps 6, adjacent to the air supply devices 9.
- the heat exchangers commu ⁇ nicate with the well 15 via a feed pipe 18 and a return pipe 19.
- the intention is that, in warm climates or for buildings with considerable cooling requirements, it should be possible to cool the incoming air directly with cold well water, as well as to condense and conduct away surplus humidity in the incoming air, such that this hu ⁇ midity is not deposited inside the construction.
- a further cooling may optionally be carried out by means of the heating medium in the pipes 4, but most favourable from the point of view of humidity is that the air is cooled to a temperature somewhat lower than the one de ⁇ sired, whereupon the air is heated when flowing through the air gap 6.
- the capacity of the air to absorb humidity and dry out the building is increased. This is important since buildings located in warm climates and equipped with cooling systems are exposed to attack by the humidity accumulating in the construction due to the water-saturated air continuously flowing therethrough.
- the present invention may be modified in many ways within the scope of the appended claims. It is, for example, not necessary that the supply air is taken in through air supply devices in the face of the building, but it may also be admitted through a lift shaft.
- a cooling arrangement of the type described above, in which the air is cooled directly by means of cold well water, may in this case be arranged in the centre of the building at the upper and lower ends of the lift shaft, and a single cooling arrangement may be enough to cool the entire building.
- the Invention also makes it possible to reduce the thickness of the floor structure for houses made of concrete. This is due to the fact that the thick ⁇ ness of a concrete floor structure is most often dimen- sioned with regard to the requisite soundproofing and not with regard to the bearing strength.
- a ceiling of the type described above may easily be made soundproof and the thickness of the concrete floor structure be reduced. In this context, a saving in concrete of 10-20% is not unrealistic.
