EFFECT OF USING INTERNAL PACKAGING MATERIALS FOR NEW BUILDING WALLS ON HEATING LOAD

الملخص

Experimental and theoretical investigation of three types of internal packaging materials(PVC, MDF, Gypsum board) for the residential building was carried out in the present work, to reduce the heating load in winter. Experiments were carried out at the University of Wasit (Al-Kut city, late 32.5N), winter season by building a small room from the sandwich panel. The room's dimensions were 2m width, 2m length, and 2.4m height. On the south wall, made two slots, the slot dimensions are 0.3m width and 1m height. Two types of walls were built in the two slots. The first wall was built from common bricks. The second wall was built from bricks covered with packaging material. The radiant time series (RTS) method was used for calculating the experimental heat losses through the walls.ESP-R was used to calculate the theoretical result. The results of the experimental work show that. The maximum values of percentage energy saving are as follows: Internal packaging materials; 22.87% MDF, 20.48% PVC, and 16.45% Gypsum board.
