Exergy performances were investigated for a 220 MW gas-fired steam turbine power plant operating at full and partial loads. The analyses relied on full and partial plant load design data. Compared to other components, boiler exergy efficiencies, 42.8%, 42.5% and 41.8%, were the least at 100%, 75% and 50% loads, respectively. The condenser exergy efficiency was least (40.29%) at 25% load. Exergy efficiencies of high pressure heater 6 were the highest across all the loads. For the entire plant, overall exergy efficiencies increased from 28.29% at 25% load to 33.18% at 100% load.

The main objective of this study is to assess both energetically and exergetically the performance of a novel auto-cascade refrigeration (NACR) cycle enhanced by an internal heat exchanger using R290/R170. In contrast to the ACR cycle with a -60°C evaporation temperature, the NACR cycle displays a COP increase of 140.78% and a 148.67% improvement in exergy efficiency. Additionally, there is a notable decrease of 13.77% in compressor discharge temperature. For an evaporation temperature of -55°C, the NACR cycle achieves a COP of 0.403 and an exergy efficiency of 14.61%, with the compressor discharge temperature registering at 126.60°C.
