Abstract: Hybrid utilization of solar and geothermal energy is an attractive option to solve the global energy crisis as well as environmental issues. A solar-assisted ground source absorption heat pump (SGSAHP) system is proposed ...

Abstract: This study investigated the feasibility of a combined cycle comprising a topping SCO2 cycle and a bottoming TCO2 cycle (SCO2-TCO2 cycle). A simple SCO2 cycle and a recompression SCO2 cycle were considered as the topping ...

Abstract: The solar-powered Organic Rankine Cycle (ORC) could solve the energy crisis and achieve low emissions because it presents a high energy conversion efficiency for a low-temperature heat source, with little impact on the ...

Abstract: This study investigated the feasibility of a combined cycle comprising a topping

Abstract: In this paper, the performance of the regenerative organic rankine cycle (ORC) working with R123 is experimentally analyzed at different heat source temperatures of approximately 85, 95, 110, and 130°C. The higher heat ...

Abstract: Utilizing the organic Rankine cycle (ORC) for waste heat recovery is an important energy conversion method. Some faults may occur in the ORC in actual operation, but few studies have focused on the fault detection and ...

Abstract: The transcritical CO2 (TCO2) Rankine cycle has been receiving more and more attention for the lower irreversible losses and the excellent thermophysical characters of CO2. However, it is hard to condense CO2 to liquid due ...

Abstract: The present paper conducts the experimental evaluation of the performance of a regenerative organic Rankine cycle (ORC) system working with refrigerant R123 and generating 10-kW-level power. The ORC system consists of an ...
