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...

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...

Adaptive monitoring of emissions in energy boilers using self-organizing maps: An application to a biomass-fired CFB (circulating fluidized bed)
Liukkonen, M.; Hiltunen, T. - In: Energy 73 (2014) C, pp. 443-452
Improvement of energy efficiency, reduction of operating costs, and reduction of harmful emissions released into the atmosphere are issues of major concern in modern energy plants. While air emissions have to be restricted due to tightening environmental legislation, at the same time it is ever...
