... 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...
