Air conditioning system consumes approximately 50% of the total energy consumption of buildings. Split-type air conditioner is the most widely used in residential and commercial buildings. As a result, enhancement on the performance of the air conditioners will yield a significant energy savings. The use of ejector as an expansion deviceon the split-type air conditioners is one method to increase the system performance. Exergy analysis on a split-type air conditioner usesan ejector as an expansion device at room and outdoor temperatures of 24oC and 34oC, respectively,yielded thepercentage of exergyreduction up to40.6%. Also, the exergy losses on in the compressor had the highest impact on the performance improvement of the split-type air conditioner.
