The Reduction of thermal environment effect by using portable secondary window
DIYALA JOURNAL OF ENGINEERING SCIENCES,
Volume 10, Issue 4, Pages 1-18
Abstract
The Environmental heat which transform to building inside through window glass is very large ( due to the large value of glass heat transfer coefficient ) .Therefore an auxiliary window made from simple aluminum frame and consisted from three layers of polycarbonate solid transparence insulation sheet is suggested .This window can be joined to the building window at inside or outside according to building design requirement .This study was carried out at Baghdad climate zone (32.2N0) through summer season (may to September ) 2015 .The test results showed that , using secondary window will reduce the electrical energy consumption used for cooling by ( 8 – 28.5)% according to glass types .
