Recovery of waste heat process through the various thermodynamic cycles: A critical review

This review study aimed at short description on most recent research available with regards to waste heat recovery (WHR) area which could be obtained with the help of various power as well as refrigeration cycles. From the literature, it is understood that WHR not only help us to reduce emission effects but even useful in energy saving that can further positively effect to the thermal performance or can be used for different purposes with the help of WHR cycles. Therefore, present study mainly discusses the literature with regard to application of various thermodynamic cycles widely employed these days for the WHR processes.
