The unit exergetic cost of the system final exergetic product is 7.92 W/W.
This temperature level leads to maximum exergetic performance for all the examined absorber types.
Maximum exergetic efficiency exceeded 11%, maximum environmental efficiency reached up to 95% at optimized process.
Table 4 Non-exergetic and exergetic cost rates and exergoeconomic indicators for the initial guess and optimal solution for a HACHP with (x_r) = 0.8 covering 15%% of the total heat load kth Decision var.
The exergetic cost was calculated for all of the flows of the GAX refrigeration cycle, the unit exergetic cost of the heat flow at the evaporator is 6.8.
Exergetic cost effectiveness (ECE) parameter is used to decide about which components will be improved.
All the curves seem to be close to each other but the curve which corresponds to 10 mm fin length leads to the maximum exergetic performance.
In this case, the maximum exergetic performance of the collector is 45.41% and it is a bit greater than in the other cases.
The global maximum exergetic efficiency is achieved for inlet temperature equal to 750 K and it is 45.3%.
The minimization of the collecting area, which means maximum exergetic efficiency, is the optimization goal in every case.
