A Study On Ability To Keep Warmth And Heat Transfer Performance Of Light Timber Structure Wall

The warm insulation and heat transfer of wood framework wall is studies in thispaper. The mainly study contents including measure and evaluate the warminsulation of wood framework wall, Research the factors that influence the warminsulation of light timber structure wall, Research the measures that can improve thewarm insulation of light timber structure wall, Research the application of computersimulation in warm insulation measurement for light timber structure wall. Theresults of the study showed:The warm insulation material, the spacing of studs and the thickness of studs allaffect the warm insulation of wall. The heat transfer coefficient of wall6,9and12meet the cold thermal design rating. In addition, the heat transfer coefficient of theall walls met the values specified in GB. The correlation coefficient between thetheoretical calculation of the wall thermal resistance and the experimental one is0.9587.According the date by the simulation of heat transfer of ANSYS, we know themaximum wall heat flux is gypsum board, and then the OSB, the minimum is theoutside warm insulation board and the studs with glass wool. The correlationcoefficient between the simulation and experimental is0.9085.
