Life Cycle Exergy Analysis of Renewable Energy Systems
نویسنده
چکیده
Exergy concepts and exergy based methods offer an insight to the understanding of sustainable energy engineering. The utilization of energy and other resources by applying physical concept as exergy and exergy based methods and the value of these tools in the design are presented, in particular Life Cycle Exergy Analysis (LCEA). LCEA is applied to a typical wind power plant. This brings a new approach and insight to the engineering conditions for a sustainable development that is further elaborated. The importance of introducing this new knowledge into present engineering education and practices is argued for.

The energy and exergy analysis of a novel cogeneration organic Rankine power and two-stage compression refrigeration cycle
The energy crisis in recent years has led to the use of thermodynamic cycles that work based on renewable energies. Low-temperature cycles—such as organic cycles—are suitable strategies for the application of renewable energies. The present study proposes a novel cycle through the integration of a two-stage compression refrigeration cycle with a combined Rankine power and ejector refrigerat...
