The deployment of distributed generation in electricity distribution networks can potentially increase their reliability and reduce the cost of power, by installing energy sources closer to the demand or consumption points. This type of generation involves a great variety of energy sources, such as; wind, solar, hydraulic, fossil fuels, biomass, among others.</p> 2020-02-06T09:09:35+00:00 ##submission.copyrightStatement## Potential energy of plant biomass: banana, coconut, cacao and corn 2020-06-06T05:48:56+00:00 Genial Belvine Epeni Tombo Edison Cedeño Zambrano Jair Loor Barreiro Jordi Medranda Posligua <p style="text-align: justify;">In this document, a study was carried out on the energy potential of plant biomass in the Portoviejo canton, since climate change is not a utopia, but the reality. Throughout this study, an overview of the capacity in biomass at the national, provincial and cantonal level (Portoviejo) was presented, a study on the culture of banana, cocoa, coconut, and corn was made since it is important to know if the canton can respond to the biomass demand of the selected plants. Then the socio-economic and environmental impacts were analyzed in a general way.</p> 2020-03-31T12:38:31+00:00 ##submission.copyrightStatement## Obtaining biogas product from biological residues vaccines in Chone city 2020-06-06T05:48:55+00:00 Janner Leonel Santos Mantuano Manuel Enrique Vergara Macías Erik Sebastian Sanchez Toapanta Klever Steven Tubay Palma María Fernanda Vivas Giraldo <p style="text-align: justify;">In this research, we studied the use of cattle biological waste to obtain biogas through a biodigester in the city of Chone, considered the livestock capital of Ecuador. Biogas is a mixed gas produced by the fermentation (anaerobic digestion) of organic materials in the absence of oxygen. It is mostly composed of methane and carbon dioxide. The biogas production process takes place in a container called a digester, in which the anaerobic fermentation process occurs. Obtaining biogas is one of the most used alternative sources for the production of renewable energy, so it can be evidenced by its importance as a tool against the fight of the environmental problem that exists today. The use of biogas of bovine origin has a high calorific value so it can be used for the production of heat, electricity or biofuel. This initiative seeks to manage and sustainably reduce organic waste, reduce the amount of greenhouse gas emitted into the atmosphere and reduce dependence on fossil fuels.</p> 2020-04-01T13:30:15+00:00 ##submission.copyrightStatement## Design and construction of an industrial ship conditioning system 2020-06-06T05:48:55+00:00 Ricardo Fabricio Muñoz Farfán Telly Yarita Macías Zambrano Fausto Roberto Andrade Badillo Adrián Adalberto Hernández Solís <p style="text-align: justify;">This project is based on the design and construction of an industrial air conditioning system for the improvement of the working thermal comfort of workers that for various reasons there is the trend of the increase in body temperature are these by machines, equipment or the same work activities, which affects the productive performance and possible health risks. During development, the selection of mechanical equipment such as the fan, water pump, ventilation transport ducts is studied with high rates of energy efficiency. In the light of the above, the environmental economic partner alternative is chosen to implement the evaporative conditioning system, conducive to working in open places to lower the temperature by labor and technology installed in the production areas, as well as the extraction of fumes derived from production processes. The importance of the evaporative conditioning system is to derive the appropriate mechanisms to take advantage of the surface heat transfer of a panel and copper and aluminum coil using water, and thus take advantage of its temperature differential reaching 25<sup>o</sup>C, with an average humidity of 66% and energy consumption of 0.29 KW/h.</p> 2020-04-30T00:00:00+00:00 ##submission.copyrightStatement## Quality management of electricity service with photovoltaic generation distributed in rural area 2020-06-06T05:48:54+00:00 Gino Joaquín Mieles Alcira Magdalena Vélez Quiroz Ciaddy Gina Rodríguez Borges Antonio Vázquez Pérez <p style="text-align: justify;">The need to search for new energy models that are integrally sustainable for the present and the future, especially photovoltaic solar energy that would contribute to a radical change in Manabí Ecuador where populations are living in rural areas away from the electricity grid, which causes impacts negative economic and in some rural electrification projects, and low quality have oriented national policies towards the search for the best alternatives, such as renewable sources, that is, the efficient use of resources and the increase in reliability, coverage, and quality in the electrical supply that Manabí has. Emphasizing "good living" as an objective of the Ecuadorian government, meeting its needs for the development of its agricultural, artisanal, commercial and industrial activities. Thus, avoiding that due to lack or poor quality of energy that prevents them from being able to carry out an activity typical of the countryside or rural areas, these people migrate to the cantonal headwaters, further thickening the cords of misery. The work presents an analysis on the quality of the electric service in isolated areas of the Chone municipality, proposing solutions that can improve the quality of the service, through sustainable energy planning using indigenous resources from the territory.</p> 2020-04-30T00:00:00+00:00 ##submission.copyrightStatement##
