Application of Graph Theoretic Approach in Performance Analysis of Refrigerants
Keywords:
Refrigerants, ODP, GWP, Graph Theory and Matrix Approach (GTMA).Abstract
The objective of this study is to develop a methodology for selection of a refrigerant between different refrigerants on the basis of their characteristics with effects. The study analyses the complete performance of refrigerants for identification and discussion of key-attributes with their sub-factors. An index is used to analyse and compare the performance of different refrigerants. Refrigerants have several positive characteristics such as zero ozone depletion potential (ODP), very low global warming potential (GWP), nontoxicity, high miscibility with mineral oil, good compatibility with the materials usually employed in refrigeration systems. An attempt is made by the authors to represent the overall effect of the identified refrigerant attributes quantitatively by employing a simple, systematic and mathematical tool to guide user in taking an appropriate decision. This is accomplished by using a graph theory and matrix approach (GTMA).
