TY - JOUR TI - Exergetic performance of vapor-compression refrigeration system with TiO2-nanoadditive in the compressor oil AU - Selimefendigil Fatih AU - Öztop Hakan F JN - Thermal Science PY - 2021 VL - 25 IS - 1 SP - 637 EP - 642 PT - Article AB - 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 nanooil for various solid particle volume fractions between 0% and 1%. Irreversibilities were determined by using the Second law of thermodynamics. It is found that a reduction in total irreversibility is achieved with nano-particle inclusion and it was significant for higher particle volume fraction.
