Analysis of Combined Heating Cooling Power Plant
Abstract: Exergy analysis is a useful concept for ecology and sustainability because it can use as a common measure of resource quality along with quantity. The exergy of an energy form or a substance is a measure of its usefulness or work potential. Plant efficiency management in first instance is concerned with thermal efficiency. Ultimately plant wants to produce as much output for least expenditure of fuel. When plant efficiency deteriorates, …

Analysis of a Medium Temperature Organic Rankine Cycle for Various Mixtures of Organic Fluids
Abstract: AbstractA blend of 70% alkane and 30% carbon dioxide (molar composition) possess low global warming potential, zero ozone depletion potential and are non-flammable. These mixtures are reported to be the potential working fluids for power generation in a transcritical condensing cycle. In this paper, detailed thermodynamic analysis is performed for the medium temperature organic Rankine cycle (ORC) with the mixtures of CO2 with propane or isobutene or isopentane. Among all …
