摘要

In this study, a new parabolic solar collector integrated combined power and refrigeration system with the thermoelectric generator (CPR-PTSC with TEG) was proposed. The suggested system was evaluated through energy, exergy, and exergo-economic analyses, and the effect of the TEG on the power generation performance was investigated. The influences of significant parameters such as pressure ratio of supercritical Brayton cycle (BC), length of parabolic solar collector, turbine inlet pressure (TIP) of transcritical Rankine cycle (RC), compressor discharge pressure (CDP) of vapor compression refrigeration cycle (VCRC) were determined. According to the results, it was found that the integration of the thermoelectric units to the system improved the exergy performance of the system with an exergy destruction rate of 803.4 kW, where it was calculated as 821.38 kW for the system without TEG. The result of parametric analyses represented that the various system parameters have the same effects on the performance of both CPR-PTSC with and without TEG. Furthermore, with the exergo-economic analysis of CPR-PTSC with TEG, the cost of generated power for TEG I and II were determined to be 0.6311 US$/h and 2.202 US$/h, respectively, and the cooling costs were calculated as 0.994 US$/h and 0.7462 US$/kWh.
