摘要:Nanofluids played significant role in enhancing the
thermophysical properties of a refrigerant which can lead to an
improved performance of the refrigerator compressor. This
study investigated the performances of four Aluminium based
nanolubricants in a vapour compression refrigeration
compressor system. Various tests which include evaluation of
the thermophysical properties and the determination of
thermodynamic parameters such as exergy, power
consumption, cooling load and coefficient of performance of
the refrigerator compressor system were carried out. The
outcome showed that the nanoparticles influenced greatly the
thermophysical properties of the base oil (Capella D) and
improved its thermodynamic properties. All the
nanolubricants showed improved better results in terms of
thermal conductivity and salinity, depicting better heat
transfer and thermal capacity. Also, the results of the viscosity
tests showed that the nanolubricants have lower values than
the conventional base oil, indicating good pumping ability of
the compressor and lower energy consumption. In addition, the
results of exergy analyses reveal that most of the nanofluids
systems generally showed better performance with higher
values. It thus can be concluded that the nanofluids systems
seem to provide better compressor/refrigerator working fluid
alternative with careful selection.
