METHOD FOR INCREASING HEAT AND ACCUMULATING ABILITY OF BUILDING ELEMENTS FROM CALCIUM SILICATE, AND ALSO BUILDING ELEMENT FROM CALCIUM SILICATE

摘要

1. A method of increasing the heat storage capacity of building elements made of calcium silicate, in particular building elements made of porous concrete, moreover, the building material is subjected to one or more phase transitions, the material that stores heat through melting (PCM), characterized in that the material that stores heat due to melting, it is added in encapsulated form during the manufacture of building elements to one or more of the starting materials and / or to one or more intermediate Recreatives Products, so that with the further manufacture of finished building elements, this material is included in them. ! 2. The method according to claim 1, characterized in that the encapsulated material that accumulates heat due to melting is added in microcapsules with a diameter of from 1 to 40 microns, preferably from 2 to 20 microns. ! 3. The method according to claim 1, characterized in that the paraffin mixture and / or wax is used as the heat storage material due to melting. ! 4. The method according to any one of claims 1 to 3, characterized in that as a material that accumulates heat due to melting, use a material with a melting point between 18 and 35 ° C, preferably between 22 and 28 ° C, and a heat storage capacity ΔН between 50 and 200 J / g, preferably between 80 and 150 J / g during the phase transition. ! 5. The method according to claim 1, characterized in that the heat storage material due to melting is encapsulated in a shell of a material that is stable at temperatures up to at least 190 ° C, preferably at least 200 ° C. ! 6. The method according to claim 5, characterized in that the material that accumulates heat due to melting, encapsulation
