Completely Recuperative Supercritical CO2 Recompression Brayton/Absorption Combined Power/Cooling Cycle: Performance Assessment and Optimization

Excessive heat losses and water consumption in cooling units are significant constraints restricting the application circumstances performances for SCO2 Brayton cycle, exchange capacity precooler (PRC) is typically 1.5 times that of power generation. Therefore, this research offers a high-integrated combined power/cooling system which two waste exchangers (WHEs) rectifier (RET) used instead PRC to achieve 100% exhaust recovery. Each component’s energy exergy models developed, operational characteristics, coupling relationships, destruction distribution examined. Results indicate that, when compared thermal efficiency considerably increased, concentration difference WHE1 pitch point have influences on performance. Further exergoeconomic optimization analysis reveals superior case mostly recommended relevant increasing rates 13.7% 9.17%, respectively, unit cost 81.33% base case. Turbine 1 (TUR1) main compressor (MCP) first second highest rates, RET generator (GEN) account roughly 34% rate 20% rate, respectively. In addition, reducing transfer differences equipment can further promote
