Experimental Heat Engineering Studies for Rational Design of Wall Structures with Reflecting Heat Insulation

At present, to provide high requirements for heat protection of external wall structures the heat insulation materials with a low coefficient of heat conductivity are used; their use don’t influence on heat losses due to the radiation process. Reduction in heat losses of a building is possible due to the use of reflecting heat insulation which reduces the heat flow passing through the external enclosing. To assess the efficiency of the use of reflecting heat insulation in the external wall enclosing structure, the experimental heat engineering studies have been conducted in the climatic chamber of NIISF RAACS. As a result, on the basis of experimental data the values of thermal resistances of air cavities having surfaces of materials with different coefficients of reflection of surfaces have been obtained. On the basis of the developed methodology and algorithms of calculation of the level of heat protection of air cavities with reflecting heat insulation and without it with the use of experimental date obtained, the efficiency of the use of reflecting heat insulation in external wall enclosings has been assessed.
