Abstract: Organic Rankine cycle (ORC), biomass combustion and single-effect lithium bromide absorption refrigeration are appealing and promising technologies for combined heat, cool and power (CCHP) system. A novel biomass-fired CCHP system incorporating ORC and single-effect lithium bromide absorption refrigeration integrated with monoethanolamine (MEA)-based CO2 capture is proposed in this paper, in which the pressurized hot water is used as heat source for ORC system and refrigeration cycle. Specifically, the condensation heat of ORC can be properly harvested for domestic hot water supplying. The refrigeration coefficient of rC is defined to characterize energy distribution relationship between ORC and refrigeration cycle. Results show the optimal evaporating temperature and heat source temperature are determined with refrigeration efficiency and net present value through gray correlation method when achieving excellent thermo-economic performance simultaneously. Besides, the optimal condensation temperature is directly affected by domestic hot water temperature. It further suggests that biomass-fired CCHP system incorporating ORC with cyclopentane owns the best thermo-economic performance with the maximum power efficiency of 7.4 %, refrigeration efficiency of 14 %, thermal efficiency of 81.5 % and primary energy saving ratio of 13.3 %. The optimized bioenergy system is thermodynamically and economically attractive, environment-friendly with negative CO2 emissions substantially attributed to CO2 capture.
