Thermodynamicsanalysis of the vapor-compression refrigeration system with various nanoparticle volume fractions of TiO 2(between 0.5%, and 1%) added to the compressor oil was performed. R-134a was used as the refrigerant. Two-step method was used to prepare the nano-lubricant for different solid particle volume fractions. It was observedthat COP of the refrigeration system enhances with the addition of nanoparticles and it is an increasing function ofnanoparticle volume fraction.eng[Fen > Temel Bilimler > Fizik, Uygulamalı]Araştırma Makalesi
