Experimental and Theoretical Study to Minimize the Cooling Load by Using a New Alternatives in a Space Located in Baghdad City

Abstract

The present investigation is concerned with the alternatives used for the cooling load reduction of a space in Baghdad. A numerical and experimental study has been accomplished in Baghdad during July and August of 2008 with the application of a new technique by a suitable alternative for minimizing the cooling load. In the experimental side of this work, a vertical aluminum flat plate is situated on the eastern and southern walls. This sheet is extended into the under ground to a depth of (1) m of a cube test room having (1) m3 size. The experimental data showed that the indoor temperature reduced from (34.5) °C to (31.7) °C and (29.9) °C when using aluminum plate with air gap and glass wool insulation respectively. The heat flux on the southern wall reduced by (23.5%) and (33.7%) for air gap and glass wool respectively. The corresponding reductions on the eastern wall were (20%) and (29.8%) for air gap and glass wool respectively. A numerical simulation two-dimensional model was performed applying a finite difference technique implemented in a sophisticated MATLAB program.
