Keeping in view the scope and wide range applications of cooling systems and refrigeration cycles, there has always been a dire need of developing economic and efficient cooling systems. In this regard, current research paper provides an overview of how the optimization of vapor absorption cycle-the most economic refrigeration cycle-can be carried out and suggests the means of its thermodynamic modeling for obtaining its better output. This will lead to accomplishing the target of providing an economic and efficient method of producing refrigeration effect.
