A REVIEW OF THERMODYNAMIC ENERGY AND EXERGY ANALYSIS OF A CASCADE REFRIGERATION SYSTEM FOR PROCESSES OPTIMIZATION

Abstract

This article presents an overview of thermodynamic energy and energy analysis with the aim of
designing, developing, and optimizing a cascade refrigeration system for energy-efficient
construction processes and ultra-low-temperature product management. A review of the classes
of cascade systems was carried out, stating the benefits and setbacks. All components of the
cascade refrigeration system were identified, explained, and designed theoretically. Energy and
exergy techniques was used to analyze every component of the system separately, modeled and
evaluated to minimize energy destruction. Necessary equations for calculating energy and
exergy destructions were outlined to ensure effective modeling and optimization of the system
processes. Exergy analysis of processes was used in detecting, quantifying, and minimizing
inefficiencies in processes. A better insight into the thermodynamic performance of the process
and the fictitious efficiency of the process was noticed. The outcome helps to identify the sites of
energy destruction and determine the maximum performance of the system. The analysis helped
in solving energy-related environmental problems, reducing the cost of operating and designing
processes, and hence ultimately leading to sustainable development. This provides a logical
basis for improving the performance of an ultra-low-temperature freezer for heat-sensitive
vaccine management. The effective modeling and building of cascade refrigeration systems for
zero energy destruction and high efficiency is made possible.
