Abstract


In the present investigation, nanofluid contains suspension of nanoparticles (Al2O3) in water (base fluid) with different concentrations (1%, 2%, 3% and 4% by volume) are prepared. Nanofluid taken as a cold fluid in the condensing unit of air conditioner and the heat transfer rate has investigated. Experimental results emphasis the enhancement of heat transfer rate by 1.77% to 37.35% due to the nanoparticles presence in the cold fluid. Coefficient of heat transfer is increases with increase in volume concentration of nanoparticles in the base fluid.
