摘要：
In the Part 1 of this paper, a variable temperature heat reservoir irreversible intercooling regenerative Brayton combined heat and power (CHP) plant model is set up, and the exergy efficiency and exergy output rate formulae are obtained. The optimization of pressure ratios and the influence analyses of some vital parameters on the exergy performances are carried out. In this Part, the heat conductance distributions about the high temperature-side heat exchanger, regenerator, intercooler, thermal consumer exchanger and low temperature-side heat exchanger, and the pressure ratios are optimized step by step. The effects of main parameters (such as of turbine and compressor efficiencies, working substance pressure drop loss, heat consumer required temperature, and so on) on the optimum exergy performances are investigated, and the heat capacitance rate matching between the heat reservoirs and working substance is studied.
