<p>Wall construction arrangement for the utilization of solar energy, e.g., in the heating of buildings. The objective of the invention is to improve the heat-economic output of wall constructions. The invention is based on the idea that at least one insulation is used whose heat conductivity is changed substantially as a function of temperature. When such an insulation is used, the wall construction functions as a sort of a heat diode so that heat is shifted mainly from outside inwards and not vice versa. The wall construction arrangement in accordance with the invention comprises a face board (1), which is substantially penetrable by the heat radiation of the sun but which is hardly penetrable by radiation of a different wavelength in the opposite direction, as well as an absorption layer (3), which is fitted inside the face board and which absorbs at least part of the heat radiation that has come through the face board (1). The insulation layer (7) which is fitted inside the absorption layer (3) is made of a material whose heat conductivity is substantially variable as a function of the temperature. This material preferably contains some liquid. The insulation material may be, e.g., cellular plastic whose pores contain moisture, or moist mineral wool.</p> |
