Summary

Successful implementation of heat pumps in the industry requires an adequate balance between two opposing goals: minimizing the system's capital expenditure (CAPEX) and maximizing the thermodynamic cycle's coefficient of performance (COP). In this study, we identify for several external conditions the working fluid and cycle layout which combined can provide end-users with the most economically attractive solution for the installation of a heat pump in their specific process. Consequently, we coupled numerical models of heat pump cycles and thermo-physical properties of working fluids with specifically developed cost models for heat pump components. The simulation results indicate that there is a trade-off between CAPEX and COP. Other economic metrics highlight the importance of a higher COP, resulting in a low operational expenditure (OPEX). Natural refrigerants result in higher COP (lower OPEX), but the added costs due to explosive environment safety for flammable refrigerants hamper the CAPEX.
