The use of the organic Rankine cycle (ORC), flash (OFC) and Kalina (KC) is proposed to enhance electricity generated by a supercritical CO2 recompression Brayton (SCRB) cycle. Novel comparisons SCRB/ORC, SCRB/OFC SCRB/KC integrated plants from thermodynamic, exergoeconomic sustainability perspectives are performed choose most appropriate bottoming for waste heat recovery SCRB For comprehensiven...

The maritime industry will continue to see increasing regulatory requirements reduce carbon emissions from ships’ operations. Improving the energy efficiency of ships with waste heat recovery systems based on organic Rankine cycle (ORC) is an attractive way meet these tightening requirements. operational profile a ship has huge influence feasibility installing ORC onboard as it affects source d...

Energy efficient systems are the most desirable systems. Due to huge rise in energy prices and lack of availability of energy, the effective use of energy has become the need of time. Energy recovery both in heating systems as well as in air-conditioning systems saves a lot of energy. In this paper energy recovery system has been designed and optimized for central air-conditioning systems for v...
