Universidad de Zaragoza Exergy assessment and exergy cost analysis of a renewable-based and hybrid trigeneration scheme for domestic water and energy supply 2019 Access copy available to the general public Unrestricted Exergy and exergy cost analyses are proposed as complementary methods for the assessment and better understanding of the efficiency of a hybrid trigeneration system based on renewable energy sources. The system combines photovoltaic/thermal collectors, an evacuated tube collector and a wind turbine and produces electricity, sanitary hot water and desalted fresh water for a single family house. The system includes two desalination technologies (reverse osmosis and membrane distillation) that consume power and heat respectively, and two kinds of energy storage devices (a hot water tank and two lead-acid batteries). The assessment is based on simulations developed by using TRNSYS software. As a first level of detail, exergy analysis is applied in ten-minute basis to selected plant components. As a second level of detail, it is proposed to apply exergy-based indicators that summarize the system behavior during a longer period of time (monthly basis). By using aggregated values, exergy accumulation terms become negligible, what allows applying symbolic thermoeconomics to calculate exergy cost and to analyze in depth the process of cost formation. The system has an exergy efficiency of 7.76% (6.68 due to electricity, 0.33 due to fresh water and 0.75 due to sanitary hot water). info:eu-repo/grantAgreement/ES/MINECO/ENE2014-59947-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 6.082 2019 2.166 2019 THERMODYNAMICS 3 / 61 = 0.049 2019 Q1 T1 Building and Construction 2019 Q1 ENERGY & FUELS 20 / 112 = 0.179 2019 Q1 T1 Civil and Structural Engineering 2019 Q1 Electrical and Electronic Engineering 2019 Q1 Management, Monitoring, Policy and Law 2019 Q1 Energy Engineering and Power Technology 2019 Q1 Fuel Technology 2019 Q1 Industrial and Manufacturing Engineering 2019 Q1 Energy (miscellaneous) 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-4408-6881 Uche, J.
