Exergy And Performance Analysis Of A CO2 Single Stage Thermal Compressor Heat Pump

A thermal compressor heat pump is a thermally driven heat pump application that mainly uses thermal
energy to drive a compression cycle, delivering heat to the user. The thermal energy can be in the form of waste
heat, combustion of natural gas, or solar, which would contribute to the demands for higher-efficiency machines
and decreasing greenhouse gas emissions. The thermal energy is directly received by the thermal compressor,
which aims to convert it into compression power, replacing a conventional electric compressor. Exergy analysis is
gaining more interest today as it offers a deep and detailed analysis of the inefficiencies in a system. Such
analysis highlights the highest deficiencies in components and the maximum possible potential for process
optimization. Being an important component, an overall performance optimization of a thermal compressor heat
pump cannot bypass the optimization of its compressor. For this reason, we carry out an exergy analysis on the
thermal compressor integrated into a single-stage heat pump cycle, based on previously derived data-driven
models. A parametric exergy analysis is carried out to find the optimal operating conditions
