... with the annual operating cost to drive the system have been presented. A thermodynamic model was first formulated using engineering equation solver (ees) software for the computation of the coefficient of performance (COP) and exergetic efficiency (ECOP). The most influential parameters like temperature...

... the coefficient of performance (COP) using two different optimization scenarios. The decision variables are defined as GC pressure (75–140 bar), evaporator temperature (−19.5–0.2 °C), and GC outlet temperature for CO 2 (16–36 °C). The model performance is constrained by the practical ranges of the GC...

..., enthalpy, and entropy of the cycle states are illustrated for aforesaid conditions as per working fluids properties in the form of quadripartite diagrams. Subsequently, the cycle was analyzed thermodynamically. The coeffcient of performance (COP) was performed for refrigeration (cooling procedure), heat...

...-water showed improved coefficient of performance (COP) compared to other top cycle refrigerants, with a COP improvement of 2.9% to 8.6%. This study demonstrates the thermal feasibility of using water as a refrigerant in low-temperature cascade systems. Using water as a refrigerant in the top cycle...

..., and the simulation outcomes are compared with the experimental test results. A correlation of a coefficient of performance (COP) which is a function of PCM temperature has been proposed. Based on the developed numerical model and the correlation, two other PCM-based heat exchangers, RT25 and RT25HC, are also...

...Adityabir Singh; Ranjan Das In this study, the compatibility of exergy destruction minimization (EDM) as the main objective is checked by plotting coefficient of performance (COP), exergy coefficient of performance (ECOP), and overall exergy destruction rate by simultaneously varying input...
