Abstract
ABSTRACT
The invention relates to a method in controlling the conditions in a dwelling-house. Heating air is circulated in a closed system through a heat-accumulat-ing bottom slab (14) in the house while supplying heat to the bottom slab or taking up heat therefrom. The heat supply from the bottom slab is directed towards the dwelling spaces by proper heat insulation (17, 19) on the upper and lower sides of the bottom slab. In order to eliminate moisture from the house moisture is driven out or kept away from the bottom slab by moisture move-ment being allowed and being directed towards the under-lying ground (22) through pores and other existing voids and passages in the heat insulation (19) at the lower side of the bottom slab, moisture movement from the bottom slab to the surroundings through the edge sur-faces of the bottom slab being prevented.

Description
o A ~IET'IO~ OF CONTROLLII~G THE CONDITIONSIN A DWELLING--HOUSE
The invention relates to a method of controlling he conditions in a dwelling-house.
The high energy costs have raised a demand for low-energy dwelling-houses. One measure of the efforts in providing low-energy dwelling-houses is that the houses have been made as tight as possib1e in order to 1~ eliminate draft which otherwise is responsible for a great part of the energy consumption during the cold season. However, when a house is made practically completely tight, moisture is largely prevented from escaping from the house. It follows in many cases that 1~ the energy problem is replaced by a severe moisture problem. The moisture trapped in the house causes decomposition ot existing wood structures in the t~ouse and is an excellent breeding ground for mould funguses which are spread to wall-to-wall carpets, furniture, clothes and other texkiles in the house where they cause an unpleasant and annoying smell. The existence of mould in a dwelling-house in ~urn may cause allergies and other diseases of the people dwelling and living in the house, and also may attract insects living on the mould funguses.
In other words, the conditions in the house will not be acceptable to people living in the house.
The most common remedy for moisture and mould in dwelling-houses is to see to it that there is a satis-factory drainage around the hous~e and that the house is insulated against penetration of moisture ~rom the outside, ventilation of the spaces wheré mould is present at the same time being provlded. Said latter measure is, of course, a charge to the energy account. However, these measures do not provide the intended eftec~ in all cases, because moisture may be trapped in the building structure :

2~) without the possibility to escape therefrom and without being available for rehabilitation steps.
The purpose of the invention is to provide such a control of the conditions in the dwelling spaces of a dwelling-house that the conditions are not injurious to health due to the existence of moisture or mould, the requirement of low-energy consumption at the same time being satisfied. The invention is based on the principle of low-energy heating of a dwelling-house, which is described in the international application with publication number WO 81/02775. In the method of the invention for controlling the conditions in a dwelling-house heating air is thus circulated in a closed system through a heat-accumulating bottom slab in the house while supplying heat to the bottom slab or taking up heat therefrom, the heat supply from the bottom slab being directed towards the dwelling spaces by proper heat insulation on the upper and lower sides of the bottom slab.
Various aspects of the invention are as follows:
An improved foundation arrangement providing for selective control of moisture and temperature related conditions of a dwelling-house built thereon; said arrangement comprising: 5 (a) a bottom slab portion having upper and lower surfaces and a side edge and being reinforced with irons;
(b) a closed heat-radiating air circulation system imbedded within said bottom slab portion; 0 (c) a first insulatin~ layer positioned above said bottom slab portion upper surface;
~Z~2~0 (d) a second insulating layer positioned below said bottom slab portion lower surface; said second insulating layer including voids and passages therein constructed and arranged from selected movement of moisture downwardly therethrough;
(e) edge insulation means constructed and arranged to provide suhstantial heat and moisture insulation along said slab portion side edge and along edge portions of said first and second insulating layers; said edge insulating means being provided ;~ with recesses for receiving said reinforcing irons and defining a wall oriented along, and outside of, said slab portion side edge;
(f) whereby said heat-radiating circulating system may be selectively actuated to substantially dry said bottom slab portion by driving moisture therein through said second insulating layer and toward ground thereunder, while simultaneously heating sald bottom slab portion.
A method of controlling moisture and temperature related conditions in a foundation portion of a dwelliny-house, said method comprising the steps:
(a) providing a first insulating layer; said insulation layer including voids and passages therein and constructed and arranged for selected movement of moisture downwardly therethrough;
(b) providing a heat and moisture insulation building element along side edge portions of:said first insulating layers; the building elements having a vertical extension greater than said first insulating layer; ~ ~
(c) using said first insulating layer and said building element as a mold when molding a bottom slab portion in the foundation; the bottom slab portion having upper and lower surfaces and a side edge;
t~l - ~Z~2~0 2b (d) providing a closed heat-radiating air circulation system imbedded within said bottom slab portion, (e) providing a second insulating layer above said bottom slab portion upper surface; and (f) selectively providing heat to said bottom slab portion through said heat-radiating circulation system; said heat driving moisture in said bottom slab portion downwardly through said first insulatiny layer and toward ground thereunder.
In order to explain the invention in more detail reference is made to the accompanying drawing in which FIÇ. 1 is a fragmentary vertical sectional view of the basement of a dwelling-house for working the method of the invention, FIG. 2 is a plan view of a building element forming part of the basement structure, and FIG. 3 is a side view of the building element of FIG. 2.
The dwelling-house fragmentarily shown in FIG. 1 has a basement which comprises building elements 10 which are set in cement mortar 11. The building elements are made of foamed polyurethane with a surface mat-rial .
129~Z~O
of cement-based panel and are constructed as shown in FIGS. 2 and 3. At each end edge thereo~ the building element has a groove 12 to be connected to an adjacent identical building element by means of a rib. At one side of the building element there are provided two recesses 13 having triangular cross-sectional form, wni ch open into the upper edge surface and extend down~
wards through the building element over substantially half the height thereof. The basement including build-1~ ing elements according to FIGS. 2 and 3 functions as amould for moulding a bottom slab 14 of reinforced construction concrete. The bottom slab extends into the recesses 13 wherein it is anchored by means of rein-forcing irons 15. In the bottom slab there is provided a passage system 1~ which can be obtained e.g. by posi~ioning metal tubes in the concrete. On top of the bottorn slab 14 a relatively thin layer 17 of heat--insulating mater;al is arranged, and on top of this layer a floor material 18, such as particle board, parquet, or similar material is arranged. Below the bottom slab there are one or several layers 19 of heat--insulating material. Below the heat-insulating layer or layers, a drainage layer 20 with drainage pipes 21 therein, is arranged and this layer is positioned on intact or compacted ground 22. A side wall 23 of an arbitrary construction is supported on top of the base-ment including the building elements lU. The basement structure of the dwelling-house described is substan-tially in agreement with the disclosure of the inter-national application mentioned above and having thepublication number WO 81/;02775, and it is also the intention that heat shall be supplied to the bottom slab 14 such that the bottom slab functions as a heat magazine, and that the insulating layers 17 and 1~
~ shall be dimensiGned in relation to each o~her such -:
. ~
' ~ ; :
~Z9~Z6~) that the heat supply from the bottom slab 14 is directed upwards into the dwelling spaces of the house. The heating of the bottom slab 14 and also the recovery of heat stored therein is effected by circulating air in a closed circuit through the passage system 16, the circulating air for heating being allowed to pass through a sun collector, a heat pump, a furnace, an electric heater, or a heater of any other kind.
The construction concrete of the bottom slab 14 provided as a heat magazine, can comprise conventional concrete, but an additive may be included therein, e.g.
an agent forming air voids therein retarding the heat delivery from the bottom slab. The reinforcement of the bottom slab can be made very simple, but since the bottom slab is relatively thick it may also be inforced by means of beams, e.g. in such cases as piling has to take place. The bottom slab can function as a heat magazine at low temperatures, and in that case the passage system 16 should be located substantially centrally of the height of the bottom slab and should be arranged in such manner that the heat when stored into the bottom slab will be distributed substantially uni-formly in the entire slab.
In addition to the function of the basement includ-ing the building elements 10, as a mould in moulding the bottom slab 14 the basement also functions as a pro-visional load support for the wall structure 23 erected on the basement, until a vault effect is obtained in the bottom slab 14 connected to the basement, all load support then being effected over the bottom slab.
The insulating layer or layers 19 should be pervious so that a fluid can pass therethrough. The layer or layers can comprise e.g. SUNDOLIT or STYROLIT
(registered trademarks) consisting of poiystyrene .~
~ ,:
~z~z~o granules with external voids, i.e. open voids or passages between adjacent granules. This means that moisture can pass from the bottom slab 14 through the insulating layer or layers 19 downwards into the drainage layer 20 and the ground 22. Therefore, when the basement is built up and immediately after moulding of the bottom slab 14, hot air can be circulated through the passage system 16 to dry the bottom slab, the moisture being driven downwards through the layer or layers 19 to the underlying ground. The heat storage in the bottom slab and the drying of the bottom slab thus can take place immediately after moulding, and if the house is built during the cold season, the cement binding can be accelerated by this procedure. Thus, the basement will be warm and dry before the house is built from the basement, which means that the building moisture problems are eliminated and no freezing of the ground below the bottom slab can take place. The build-ing elements 10 function as a moisture barrier at the edge surfaces of the bottom slab 14, and therefore the moisture in the bottom slab which is driven from hotter areas to colder areas, will be driven down into the ground below the bottom sl~b and moisture will be effect;vely prevented from penetrating into the house from below. There is obtained a temperature gradient in the basement structure securing that the dew point and thus the moisture precipitation will be located at the underlying ground 2~ or possibly to the surface thereof.
However, no moisture precipitation will take place in the basement structure proper and as a consequence thereof the existence of moisture and mould in the portions of the house which are in contact with the basement structure, is eliminated.
~ If the air circulating in the passage system 16 is allowed temporarily at uniform intervals to reach a high ~2~ 0 temperature, e.g. about 150C, which can be controlled by means of proper electronic apparatus, the passage system will be sterilized. Since the circulation system, moreover, is a closed circulation system, spores and bacteria cannot be supplied to the passage system from the outside, which al1 guarantees that there is no breeding ground whatsoever for funguses and bacteria in the passage system.
The temperature of the heat magazine formed by the bottom slab 14 can vary between e.g. 22C and 37C.
Then, the insulation 1ayer 17 should be calculated such that there is obtained a maximum temperature at the surface of the floor material 18 ot 21.5C. However, if it is desired to have a higher surface temperature 1~ of the floor, e.g. about 25C, as in a bathroom, the thickness ot the insulating layer 17 should be made smaller. The purpose of this insulating 1ayer is above a11 to retard the heat supply from the bottom slab 14 and to provide a uniform temperature distribution on the floor surfaces.
By a dwelling space being heated in the manner described, i.e. by controlled heat supply from a bottom slab arranged as a heat magazine, the differences between the surface temperatures of f100r, wa11s and ceiling will be at minimum, and as a consequence thereof there will be no significant redistribution of positive and negative ions in the space and thus no static electricity, which is contrary to heating of houses having a common "cold" basement structure and radiators wherein the temperature differences of the surfaces can be of the order of 50C. Consequently, the collection of dust will be reduced, because the dust particles have no tendency or combining to larger aggregates in the absence of static electricity.
Within the scope of the invention this can be B
lZg4Z60 applied also to other house constructions than that described herein in order to illustrate the invention.
