Comparative analysis of a solar trigeneration system based on parabolic trough collectors using graphene and ferrofluid nanoparticles
2020
In this comparative study, the thermodynamic analysis of a trigeneration
system driven by a parabolic trough solar collector based on two different
types of nanofluid is performed. A standard trigeneration system consists of
two subsystems, including an absorption heat pump and the organic Rankine
cycle. Two types of nanoparticles (graphene and ferrofluid) that possess
excellent and diverse physical properties within a base fluid (Syltherm 800)
were selected to be the absorption fluids in the solar cycle. Four organic
fluids, namely R123, R401a, R601, and R601a, for the organic Rankine cycle
are examined. The results clearly depicted improvement in the system
performance. It was found that graphene nanoparticles performed better as
compared to the ferrofluid nanoparticles. The largest temperature of the
collector outlet was obtained at 257.4℃ with Syltherm 800/graphene. The
highest net power produced by the system was 134.1 kW and the maximum
overall energy and exergy efficiencies of the system were 160.5% and 21.84%,
respectively. The highest net power produced by the system was 134.1 kW and
the maximum overall energy and exergy efficiencies of the system were 160.5%
and 21.84%, respectively. The solar collectors are the main source of the
exergy destruction and the highest value was recorded about 683kW.
