3. CONCLUSIONS The dispersion of nanoparticles in the lubricant resulted in overall performance enhancement of compressor. The working was found to be smoother and consuming lower power. The increase of rate of heat transfer in the evaporator and the lower power consumption facilitated an increase in COP of the system. The kinematic viscosity of the lubricant also showed an appreciable increase. The economic viability of the process is very promising. The cost of nanoparticles is Rs. 18,000/100g but each charging requires only a very low volume fraction of nanoparticles which costs only about Rs.15/-. Hence the use of nanofluids is economically feasible and paves a new path as an effective lubricant. ACKNOWLEDGEMENT The author wishes to thank Centre for Nanoscience and Nanotechnology, M.G.
