Abstract

In this study, cooling
performance of a refrigeration system under the effects of nanoparticle (TiO₂)
addition to the compressor oil (poly alkaline glycol (PAG)) was experimentally
investigated. Thermodynamics analysis of the vapor-compression refrigeration system
with various nanoparticle volume fractions of TiO₂ (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 observed that COP of the
refrigeration system enhances with the addition of nanoparticles and it is an
increasing function of nanoparticle volume fraction.
