| Abstract | ||
| The present work includes cooling load measurement in Iraq. One room located in Baqubah was the object of the study. The measurement was taken for the room in summer months of 2004 (i.e. in May, June, July, August & September). The area of test room was 15 m2 and 3 m ceiling height with medium weight construction specifications. The test room includes exterior east and west wall facing, un-conditioning adjacent space with an exterior roof, east window and an exterior west door. The air conditioner unit used in this work was a window type with a nominal capacity of 2 T.R. (7 kW). The theoretical cooling load was predicted by three methods of cooling load calculation, which are TFM, CLTD/SCL/CLF & TETD/TA methods. Measurement of cooling load showed that there is a large difference between the measured and predicted cooling load with all theoretical methods. The difference ranged from 33% to 40%. This large difference is appear because of the several season such as the air conditioner type, suffer environmental and the construction specification of the test room where it’s represent the Iraqi building and not exactly same as building specification tabulated in ASHRAE tables | ||
