Examination and optimization of a novel auxiliary trigeneration system for a ship through waste-to-energy from its engine

Considering the thermal processes with the help of smart heat recovery, this study proposes a novel auxiliary trigeneration system for a ship based on the waste heat of its engine to produce electricity, cooling, and freshwater. The system consists of a regenerative organic Rankine cycle (RORC) with...
