Highlights•A novel trascritical CO2 trigeneration system driven by low-grade heat resource is presented.•System performance is investigated from the thermoeconomic viewpoint.•The effects of key operating parameters on system performance are identified.•Multi-objective optimization for the system in different operation modes is carried out.AbstractThis work focuses on designing a self-sufficient trigeneration system for low-grade heat resource applications. For this purpose, a novel transcritical CO2 combined cooling, heating, and power (CCHP) system is proposed, which integrates a Rankine power cycle and an ejector refrigeration cycle (ERC). To evaluate the feasibility of the proposed system, the mathematical model of the combined cycle is built and validated. The effects of seven key parameters on system performance are investigated from the thermoeconomic viewpoint. Furthermore, multi-objective optimization is performed for the system when it generates both cooling and power or simul
