Exergetic performance of VCR system with TiO2-nano additive in the compressor oil

ABSTRACT
Exergy analysis of a vapor-compression refrigeration system with TiO2 nanoadditives in the compressor oil was performed. Two-step method was used for the preparation of nano-oil for various solid particle volume fractions between 0% and 1%. Irreversibilities were determined by using second law of thermodynamics. Reduction in total irreversibility is achieved with nanoparticle inclusion and it was significant for higher particle volume fraction.
