In the present study, thermo-economic analysis of a combined solid oxide fuel cell (SOFC) with a gas turbine, a generator-absorber heat exchanger (GAX) and heating process heat exchanger for heating, cooling and power production as a tri-generation system is conducted. Also, an external steam reformer is applied to convert methanol as oxygenated fuel to hydrogen for the electrochemical process ...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

This paper studies planning problems for a group of heating systems which supply the hot water demand for domestic use in houses. These systems (e.g. gas or electric boilers, heat pumps or microCHPs) use an external energy source to heat up water and store this hot water for supplying the domestic demands. The latter allows to some extent a decoupling of the heat production from the heat demand...

This involves having production units distribute to the consuming units through a single vertical and central distribution network. Each fl oor is served by an indirect connected substation (Figure 3). Enhancing comfort1 and reducing energy demand2 is possible when fl oorto-fl oor (rather than building-to-building) consumption is moderate (cooling) or low (heating) temperature radiant-based sur...

We have performed molecular dynamics (MD) simulations of zeolite-guest systems driven by microwaves (MW), to study how energy is distributed in these systems as a function of guest loading. Expanding on a previously published communication [Blanco, C.; Auerbach, S. M. J. Am. Chem. Soc. 2002, 124, 6250.], we have found that MW-driven MD with the Andersen thermostat gives robust steady states, wh...
