Health monitoring methodology based on exergetic analysis for building mechanical systems
George, E.N.; Bailey, M.B.; Domigan, W. - In: Energy 35 (2010) 3, pp. 1216-1223
Exergetic analysis is not often performed in the context of retrocommissioning (RCX); this research provides insight into the benefits of incorporating this approach. Data collected from a previously developed RCX test for an air handling unit (AHU) on a college campus are used in an advanced...

Exergetic optimization of single level combined gas–steam power plants considering different objective functions
Bracco, Stefano; Siri, Silvia - In: Energy 35 (2010) 12, pp. 5365-5373
Combined cycle power plants have been studied in this paper with the aim of optimizing the heat recovery steam generator using a first and second law approach. To this end, a mathematical model has been developed for determining the optimal steam pressure in a one pressure level heat recovery...

Exergetic analysis of an innovative small scale combined cycle cogeneration system
Badami, M.; Mura, M. - In: Energy 35 (2010) 6, pp. 2535-2543
The purpose of this paper has been to carry out an exergetic analysis of an innovative natural gas (NG) combined cycle cogeneration system (150-kWe, 192-kWt). The combined cycle is composed of a reciprocating Internal Combustion Engine (ICE), which is used as the topping cycle, and a water...

Simulation and exergetic evaluation of CO2 capture in a solid-oxide fuel-cell combined-cycle power plant
Petrakopoulou, Fontina; Lee, Young Duk; Tsatsaronis, George - In: Applied Energy 114 (2014) C, pp. 417-425
The incorporation of fuel cells into power plants can enhance the operational efficiency and facilitate the separation and capture of emissions. In this paper a fuel-cell unit, consisting of solid-oxide fuel-cell stacks, a pre-reformer, and an afterburner is incorporated into a combined-cycle...

New deep-freezing process using renewable low-grade heat: From the conceptual design to experimental results
Le Pierrès, Nolwenn; Stitou, Driss; Mazet, Nathalie - In: Energy 32 (2007) 4, pp. 600-608
An exergy-based analysis applied to ideal thermochemical dipoles allowed to design an original process that could use low-grade energy, produced from a thermal solar collector at around 70°C, to provide low-temperature cold, below −23°C, in order to store deep-frozen food. The ideal...

Economic Approaches to Ecosystem Analysis
Eichner, Thomas; Pethig, Rüdiger - 2001
Ecological systems (ecosystems, for short) are complex systems of interacting species, plants and animals, where each of the species consists of individual organisms that interact with organisms of the same or other species in various ways: they compete for scare resources and they are involved...
