The
main purpose of this study is to improve the energy efficiency of a
refrigerated facility by means of exergetic analysis. In order to achieve this
goal, we have evaluated the input exergy flows of the whole system to deduce
the exergetic yields, which are compared to the degree of irreversibility in order
to have a qualitative measurement of energy losses. The concept of exergy is
the part of energy that is virtually converted into work. The exergetic
analysis was performed on a refrigeration
unit ZR22K3E Copeland Scroll. The results of this analysis are consistent with
the condition, that the exergetic performance, which is: 36.57% and it is
approximately equal to the degree of irreversibility which is 37.50%. This
approach provides a comprehensive, standard and rigorous framework for the
analysis of energy systems, and thus for the understanding and systemic
management of the energy challenge.
