WINDOW MODULE Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: window module has window casement, light-permeating glazing material, and light-transparent heat-reflecting coating located through height of window opening. Light-transparent heat-reflecting coating is of thickness δ_x which is non-uniform in height of glazing, and with degree of blackness ε_x which both are determined according to formulas: δ_x= δ_o+A(X/h(1,2)ⁿ;, where X - distance from lower boundary of light opening derived from condition of ε_x= ε_o+B(X/h(1,2); 0<X<h(1,2;h₁) - height of area with heat-reflecting coating, h₂ - thickness of deposition made by spraying at distance X; X,δ_o - local value of blackness degree of light-transparent heat-reflecting coating at distance X; X,ε_o - local value of blackness degree of light-transparent coating at lower point of glazing X=0, A, B, m, n - constant coefficients determined from conditions of retaining standard light-engineering parameters of premise at reaching of maximal increase of heat protection O. Application of aforesaid embodiment of window module allows for enhancing thermal resistance of window modules with singular casements and with single- and double-chamber window glass units, also separate and dual casements without loss of illumination at work surface remote from light opening. EFFECT: higher efficiency. 3 cl, 7 dwg
