Abstract

In the recent years, many researches have been focused towards the new technology in heat exchangers. Besides, the economy of manufacturing takes up a great attention of scientific works. Through this work the use of microchannel condenser achieves increase in energy. The study was conducted on two air conditioning units utilize R-22 as a refrigerant and having different cooling capacities 3516 W and 5274 W. The results showed that the use of microchannel condenser achieves increase in Energy Efficiency Ratio (EER) which reflected on the total efficiency of the device and reduce energy cost. The obtained results indicated that, the use of microchannel condenser led to increase in EER by (4.3:11.3%) for the first unit and and (9.5:29%) for the second one compared with that unit use FTC. Also, the use of MChC led to decrease the pressure drop by (20%:30%) while the convective heat transfer coefficient is improved by (61.6:84.1%).
