The main aim of this work is to explore the effect of ZnO nanoparticles on the thermo physical properties of base POE oil and performance of the air conditioner working on vapour compression cycle. In this work nanolubricant of 0.2%, 0.6% and 0.8% concentrations were prepared by mixing ZnO nanoparticles of 30 to 60 nm size in the POE oil. The experimental data reveals that the thermal conductivity and viscosity of nanolubricant is high at 0.8% by weight concentration and hence 0.8% by weight concentration is selected for experimental performance evaluation. Therefore, nanolubricant in vapour compression system is the passive approach to get better performance of the system. An investigational result concludes that the system works normally and safely with the addition of nanolubricant. COP of the air conditioner along with nanolubricant has been enhanced by 38% at 0.4Kw heat load due to reduction in the compressor power and increase in the refrigeration effect. Experimental results show that the compressor power has been reduced by 33% and refrigeration effect has increased by 7.8% with the supplement of ZnO nanoparticles to the base POE oil for 0.4Kw heat load. Results indicate that the time taken to reach 20°C from 38°C in the conditioned space is reduced by 33% for ZnO nanolubricant. Thus, the ZnO nanolubricant can be used in the refrigeration and air conditioning system to improve the performance.
