Enhanced Performance the Air-Conditioning System by Adding Al2O3 to the Compressor Oil Abstract

Scientists are striving to discover new methods to reduce energy consumption in response to the high demand for energy. The purpose of this article is to find how adding nanoparticles to the compressor oil can enhance the cooling of an air conditioner and to compare this oil to natural oil without nanoparticle addition. Nanomaterial’s were added to the compressor oil at a mass concentration of 0.2%. Nanoparticles (Al2O3) were prepared, and then the stability of the nanoparticles was evaluated through direct monitoring, and this monitoring was done over different time periods. The results obtained showed that conditioning leads to enhancement when adding nanoparticles to the base oil present in the system, by making a comparison with the use of oil alone. The results showed an increase in the cooling rate of the Nano-oil system by an increase estimated at (16%), while the increase in the efficiency of the Nano-oil system was higher than that, reaching (19%) in the case of comparison with the traditional system used in the system. Another result obtained is that when solid nanoparticles are added to the cooling oil in the system, this leads to an improvement in the thermo physical properties of the system by an estimated rate of about (14%).
