Design of a combined cooling, heating and power system aboard ships

Internal combustion (IC) engines are the major source of motive power in the ships. one of the improvable method is getting waste heat energy of diesel engines and reusing it to produce electricity, cooling and heating. in this study a combined electricity, cooling and heating system based on regenerative Rankine cycle with open feed water heater and absorption refrigeration cycle is offered to recover the waste heat of engine coolant and exhaust gas to generate electricity, cooling and heating. maximum electricity output is 3471 kW and cooling output relevant is 17601 kW. effect of evaporator temperature, condenser temperature, extraction pressure are studied to optimize electricity produced with rankine cycle.
