Item Análisis de un sistema energético alternativo para el calentamiento de agua sanitaria en la compañía de economía mixta hotelera y turística Ambato(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Gamboa Vargas, Luis Alberto; Gavilanes Martínez, Sebastián Raúl; López Velástegui, Jorge EnriqueThe experimental work is focused on mitigating the emission of greenhouse gases from the burning of Liquefied Petroleum Gas, while operating a Solar Thermal System (SST) that is nearing its useful life, since its installation dates back to 2013, so it is appropriate to consider new alternatives to reduce the environmental impact and supply the energy demand of 59,533.43 (kWh/year). For sanitary water heating, the operational percentage was calculated, the main system is (SST) same that covers 57 percent and the auxiliary system comprises the use of 4 heaters that cover 43 percent, in this sense, the historical data survey was performed during the period (2018-2023), because the hotel demand was directly affected by the pandemic of COVID-19, the data obtained were essential to raise the real situation of the hotel and as a result the study of the different alternatives of thermal generation for Sanitary Hot Water (SHW) was carried out. In order to mitigate the consumption of LPG, different alternatives were established to cover the energy demand: Solar Thermal Collectors, Condensing Gas Boilers and Heat Pump. Based on different configurations, it was determined that the most viable option is the Mixed System between Heat Pumps and Solar Thermal Collectors, because it meets the previously established energy demand and at the same time its operating cost is lower compared to the other proposals.Item Análisis del suministro de energía para el calentamiento de agua sanitaria del hospital general Ambato (IESS)(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-09) Medina López, Patricio Camilo; López Velástegui, Jorge EnriqueIn the first phase of this study, the equipment that is part of the process for the heating of sanitary water in the machine room of the Hospital General Ambato IESS was identified. These components were classified according to their function, whether for the generation and distribution of steam and the exchanger, which is responsible for taking advantage of this fluid in order to add heat to the water that is then distributed to all the blocks of the institution. For the heating of the hospital's sanitary water, 35.526,152 gallons of Diesel No. 2 are required per year for steam generation. Calculations were made of the system losses during the most current period (April 2022 - July 2023) in order to identify any anomalies affecting the operation of the system, by analyzing numerical and quantifiable data. This resulted in an exchanger effectiveness of 41.46 percent. Thermal generation alternatives for sanitary hot water were proposed with the purpose of reducing the consumption of fossil fuels, establishing four possible systems to cover the energy demand, which are: solar thermal collectors and heat pumps; solar thermal collectors and steam; heat pumps and finally the recovery of sensible heat from the dry gases of the boiler chimney, determining that the most viable option are heat pumps because they cover the calorific consumption required per year, additionally its return on investment is shorter compared to the other processes, because approximately in a year and a half the financing will be recovered.Item Diseño e implementación de un sistema fotovoltaico para el suministro parcial de energía de la unidad educativa Huachi Grande(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-08) Tonato Palomo, Denisse Anabel; Tutin Chicaiza, Riquelme Estefania; Mayorga Pardo, Alex SantiagoThis technical project was applied in the Huachi Grande Educational Unit of the city of Ambato in order to provide electricity to the administrative area, since there is no good infrastructure design, so it does not have enough spaces for the entry of natural lighting, in addition, the electrical wiring is in poor condition as there are no short circuits in some areas of the institution, causing them to run out of electricity on several occasions. For this project, the necessary components for the installation will be selected taking into account different design parameters such as the calculation of the energy demand of the 15 bulb-shaped luminaires, which is the basis for subsequent calculations. Using alternative selection tables, the specific components for the photovoltaic installation were chosen. With the components already selected, the photovoltaic installation is carried out in the institution to supply energy to the established areas. Finally, performance tests were carried out on 2 specific days: sunny, cloudy and at night, with a certain load value. Under these conditions, the voltage and current intensity at the input and output of the solar inverter were measured, obtaining the behavior of battery consumption and ensuring that the photovoltaic system is working correctly.Item Cálculo de la distribución espacial y temporal del consumo de energía en el sector residencial del Ecuador entre 2010 y 2050 a una resolución de 1 km2 por hora usando sistemas geográficos de información(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2022-01) Borja Cáceres, Rodrigo Alexander; Pérez Salinas, Cristian FabiánThis research based on geographic information systems GIS aims to be a database source that relates climatic conditions, population density with energy demand in order to be used to optimize energy consumption at the national level, in addition of estimating energy demand for end-uses for decades to come. Through the temporal estimation that was carried out for each hour of each month and spatially for each square kilometer, the calculations were carried out that allowed identifying the energy demand for heating and ventilation of homes, water heating and lighting and electrical appliances. A summation of each generated raster was made to determine a National demand, in addition to which it was possible to determine hourly demand profiles, especially for the two Ecuadorian metropolises. For energy projections, the combination of populations and estimated consumption under SSP2 parameters was used, while for climate projections the RCP 8.5 scenario was used. The resulting data set for the years 2010, 2015, 2020, 2030,2 040 and 2050 is designed for use in: a new integrated assessment model called MUSE and in any analysis of energy end-use technologies in the residential sector.Item Diseño e implementación de un sistema de generación de energía eléctrica mediante celdas fotovoltaicas ubicada en las riveras del río Payamino de la ciudad del Coca para la empresa Orellana Turismo EP(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-09) Viera Andi, Jonathan Andrés; Mayorga Pardo, Alex SantiagoThe present technical project was applied for a house-building room of the Yasuniland Park in Coca city in order to provide energy to the place and to reduce the use of an electric generator avoiding air pollution with carbon dioxide and noise in nature. This project took into account the factors that affect photovoltaic installations such as the existing solar radiation in the area, which was taken from the National Renewable Energy Laboratory (NREL); and with the energy demand that the house has calculated the number of solar panels, the number of batteries and the type of regulator and inverter, in addition fuses were added to avoid short circuits which will provide greater security to the equipment. For this system a connection was designed in parallel with the solar panels and batteries, which increased the potential and obtained greater capacity of energy accumulation, which was regulated by the use of a solar controller, which allowed a system voltage of 12V. Finally, it was tested in 3 specific days: sunny, partially cloudy and cloudy, with a certain load value. Under these conditions, voltages, amperages and power were measured at the input and output of the solar regulator, achieving the behavior of the consumption of the batteries and ensuring that the photovoltaic system is functioning correctly
