Abstract:
Exergoeconomic investigations are carried out for different cycle designs (e.g. the Standard-Cycle, the Recuperator-Cycle and the Saturator-Cycle) and at different scales (0.5, 1.0 and 5.0 MWth). The focus of the simulations will be R245fa as a working fluid. The simulations are carried out with Aspen and the heat exchangers are modelled in Aspen-Plus with a shell-tube-design. The costs of these are estimated with available cost functions. The following question is answered: Which optimization measure in the cycle design is economic and beneficial for which size of the waste heat source?
