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 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...
