This study investigates task -blind and task -specific training methods to determine appropriate radial basis function based neural network architectures. These neural nets identify system behavior of air-cooled chiller condensers by grouping dominant features (clustering) of measured chiller performance data. Task specific clustering proved superior but more computationally demanding than task...

This work applies the second-law analysis of thermodynamics to quantify the exergy destruction of the components of screw liquid chiller, and to identify the potential for each component to contribute to improve the overall energy efficiency of the system. Three screw liquid chiller units were built to demonstrate the feasibility of the model presented herein. Unit A was a 100 RT water-cooled s...

The dairy industry uses a number of energy intensive thermal processes like cooling, heating and cleaning that require electrical energy. Those use temperatures between 4 °C 200 could be potentially powered using solar but one the main challenges is complexity selection integration components used for system such as collectors, cooling equipment. with temperature requirements 300 400 are mainly...

Chemical looping process (CLP) is a promising technology for in-situ CO2 capture without energy penalty. Direct CLP has more compact structure, favorable economic competitiveness, and larger reduction of exergy loss compared to syngas CLP. In this work, novel biomass direct chemical combustion (CLC) driven tri-generation system the production cooling, heating, power proposed. The proposed conta...

Sustainable greenhouses have gained relevance in recent years due to their potential reduce the carbon footprint of agricultural sector by being integrated with renewable systems, contributing decarbonization energy. Although solar technologies tend be more accessible cover system’s energy demands, are subject installation area restrictions, limiting potential. This research evaluates advantage...

Campylobacter spp. cause foodborne illnesses in humans primarily through the consumption of contaminated chicken. The aim of this study was to evaluate the United States Department of Agriculture's (USDA) recommended methodology, protocol MLG 41.02, for the isolation, identification and direct plate counting of Campylobacter jejuni and C. coli samples from the broiler slaughtering process. A pl...
