Determining the source of irreversibilities in the system with the aid of energy and
exergy analysis and decreasing the losses of the system would result in more efficient systems.
Additionally, to evaluate the TSI based on the second law of thermodynamics, an all-inclusive
exergy balance of the ORCs is carried out.
Such aspects can be physically assessed through a thermodynamic property called
exergy, which in layman term represents useful energy and is a measure of the quality of any natural or man-made system with respect to its surrounding environment, also referred to as dead state.
The main goal of this analysis was to obtain the optimal operating area of the TG steam turbine in which will be achieved maximum
exergy efficiencies and minimum
exergy destructions, for every turbine operating point.
Li analyses the performance of semiconductor materials under small temperature difference from a perspective of
exergy, put forward to getting
exergy efficiency as evaluation parameters, and found that with the decrease of the temperature difference, the efficiency of semiconductor thermoelectric generator decreases obviously, but basically
exergy efficiency stays stable [76].
Also, Mahmud and Fraser [17] have done second law analysis to conserve
exergy of a thermo-fluid setup.
Simultaneous application of nanofluid as a coolant and an organic paraffin wax as a phase change material (PCM) on the
exergy and energy efficiencies of the PV/T system is investigated experimentally by Hosseinzadeh et al.
Therefore, roundtrip efficiency based on
exergy analysis which is based on the second law of thermodynamics would be beneficial in better understanding the characteristics of the different types of OCAES systems.
Electricity output, cooling output, primary energy ratio and
exergy efficiency is chosen as objective functions.
When the proponent of the new technology cannot explain in plain English how it works, or resorts to throwing in "pseudoscience," particularly if the justification relies on some vague reference to "entropy" or "
exergy" (two favorite concepts misused by sellers) without any meaningful calculation in support, alarm bells should definitely ring.
As increased demands are placed on cold storage requirements, retailers will need to find new ways to control costs, notes Amrit Robbins, CEO of Axiom
Exergy, based in Richmond, Calif.
