The impact of the inclusion of this technology in the energy matrix in the Andean city of Cuenca, Ecuador, is analyzed. In Ecuador, liquefied petroleum gas (LPG) is currently used to heat water due to the high state subsidy, with a cost of 0, 11 USD for an LPG kg compared to the international price of 1.18 USD a Kg of LPG in 2021. Sustainability indicators show that the urban energy matrix would be minimally affected by a high penetration of solar thermal systems. The indicators that are positively affected are related to energy self-sufficiency, emissions, and employment at the expense of an increase in the cost of energy. Moreover, the analysis of the impact on consumption exclusively in the residential sector shows that liquefied petroleum gas consumption would drop from 73 to 64%, mainly because the liquefied gas is used in cooking. However, the change in technology is limited by the subsidized cost of liquefied petroleum gas, which makes the adoption of this technology difficult in the current state.

[SPA] El intenso cambio de conciencia medioambiental por el cual ha apostado la Unión Europea en los últimos años está provocando una revolución masiva en todos los sectores y, como no podía ser menos, especialmente en el industrial. Durante el presente trabajo de fin de estudios se pretenderá dar una solución coherente a un problema propuesto por dos grandes multinacionales del ámbito energético. El proyecto tiene su origen en el evento organizado por Endesa e Isover Saint-Gobain, “Premios Eficiencia Industrial Isover 2018”, del cual se espera obtener propuestas de diferentes universidades nacionales para el aprovechamiento de parte de la energía derrochada en una de las centrales térmicas de las Islas Canarias. El presente trabajo, por tanto, hace constantes referencias al Trabajo de Fin de Máster “Modelización y simulación de un sistema integrado de recuperación, almacenamiento y valorización energética del calor de los gases de escape de los equipos de potencia de la Central Térmica de las Salinas”, de Enrique Moya Tárraga, a través del cual recibe su sentido completo. El fin al que se pretende llegar es el de realizar un análisis económico de la propuesta de solución para la explotación del calor residual de los equipos generadores de la isla. Dicha solución, a su vez, dependerá de la misma viabilidad técnica, económica y ambiental que se está buscando, generando así un problema retroalimentado. [ENG] The severe environmental awareness for which the European Union has opted in recent years is causing a massive revolution in all business areas, especially in industrial sector. Along this Final Master Project, it will be intended to find a consistent solution to a problem purposed by two energetic multinational companies. The project has its origin in the event organized by Endesa and Isover Saint-Gobain, “Premios Eficiencia Industrial Isover 2018”, through which it’s possible to obtain submissions of different national universities in order to make use of part of the waste heat in one of the thermal power stations in Canary Island. Thus, the present work constantly alludes to Final Master Project “Modelización y simulación de un sistema integrado de recuperación, almacenamiento y valorización energética del calor de los gases de escape de los equipos de potencia de la Central Térmica de las Salinas” (Enrique Moya Tárraga, 2019) through which obtain its full meaning. The aim to achieve is to perform a financial analysis of the solution purposed to profit the waste heat of island diesel and gas generators. This solution will depend on technical, financial and environmental viability, so a feed-back problem is created. ; Escuela Técnica Superior de Ingeniería Industrial ; Universidad Politécnica de Cartagena

En este proyecto se aborda el diseño de un distrito térmico de uso mixto para la generación de energía eléctrica, a base de gas natural, y térmica, con agua helada, cumpliendo con la demanda de un complejo administrativo ubicado en ciudades caribeñas. Es de vital importancia la implementación de este tipo de tecnologías en el mercado actual debido al constante crecimiento de los requerimientos energéticos en estas ciudades y que, a largo plazo, es muy rentable. El enfoque de este proyecto está centrado en el diseño del cuarto de máquinas de un distrito térmico, utilizando tecnologías de cogeneración para la producción de electricidad y frío y, además, realizar su estudio económico. El proceso de diseño consistió primero que todo en una investigación respecto a los distritos térmicos, luego se realizó una búsqueda exhaustiva de fabricantes y equipos. Seguidamente haciendo uso de la información de los fabricantes se procedió a la generación de ideas y alternativas que cumplieran con los requerimientos del proyecto, estas opciones de diseño fueron validadas con la metodología de AHP. La alternativa seleccionada constó de un arreglo de chillers eléctricos, como también de un chiller de absorción haciendo uso de motores a gas natural para la generación eléctrica. Las limitantes encontradas para la realización de este proyecto fueron la falta de información de detalle que nos podían proporcionar algunos fabricantes de los equipos. Lo conseguido por este proyecto fue el diseño exitoso de un distrito térmico cumpliendo las demandas requeridas por el cliente, y generando excedentes de energía que pueden ser usados por otros clientes, así como también para futuras aplicaciones. El análisis financiero del proyecto resultó en un proyecto atractivo para los inversionistas, así como también para los usuarios que demanden la energía. ; This Project addresses the design of a mixed-use district cooling for the generation of electricity, based on natural gas, and thermal, with cold water, meeting the demand of an administrative complex located in Caribbean cities. The implementation of this type of technology in the current market is of vital importance due to the constant growth of energy requirements in these cities and that, in the long term, is very profitable. The focus of this project is centered on the design of the machine room of a thermal district, using cogeneration technologies for the production of electricity and cold, and, in addition, conducting its economic study. The design process consisted first of all in an investigation regarding thermal districts, then an exhaustive search of manufacturers and equipment was carried out. Then, making use of the manufacturers' information, ideas and alternatives were generated that met the project's requirements. These design options were validated with the AHP methodology. The selected alternative consisted of an electric chiller arrangement, as well as an absorption chiller using natural gas engines for electricity generation. The limitations found for carrying out this project were the lack of detailed information that some equipment manufacturers could provide us. What was achieved by this project was the successful design of a thermal district meeting the demands required by the client, and generating surplus energy that can be used by other clients, as well as for future applications. The financial analysis of the project resulted in an attractive project for investors, as well as for users who demand energy.

El objetivo principal del Trabajo Fin de Grado es definir geométricamente y modelar la espuma metálica en la que se embebe el material de cambio de fase estudiado (Phase Change Material, PCM). El PCM constituye el relleno de la matriz metálica porosa que actúa como superficie extendida de un intercambiador de calor para acumulación de energía solar térmica (Thermal Energy Storage, TES). Una vez definida la geometría, se desarrollará una metodología de simulación numérica, que permita evaluar, y caracterizar, el proceso de fusión/solidificación (cambio de fase) del PCM, así como, la mejora que se produce en dicho proceso de carga y descarga de energía, en forma de calor sensible y latente, al aumentar la superficie de transferencia. El Trabajo Fin de Grado incluye realizar una revisión bibliográfica en relación con las estrategias de modelado de la espuma metálica a nivel macroscópico y/o microscópico, en función de sus características geométricas, así como, de los modelos numéricos utilizados por otros investigadores para simular el proceso de fusión/solidificación, teniendo en cuenta efectos como la convección natural, o el cambio de volumen del PCM durante el proceso de cambio de fase. ; Escuela Técnica Superior de Ingeniería Industrial ; Universidad Politécnica de Cartagena

The impact of the inclusion of this technology in the energy matrix in the Andean city of Cuenca, Ecuador, is analyzed. In Ecuador, liquefied petroleum gas (LPG) is currently used to heat water due to the high state subsidy, with a cost of 0, 11 USD for an LPG kg compared to the international price of 1.18 USD a Kg of LPG in 2021. Sustainability indicators show that the urban energy matrix would be minimally affected by a high penetration of solar thermal systems. The indicators that are positively affected are related to energy self-sufficiency, emissions, and employment at the expense of an increase in the cost of energy. Moreover, the analysis of the impact on consumption exclusively in the residential sector shows that liquefied petroleum gas consumption would drop from 73 to 64%, mainly because the liquefied gas is used in cooking. However, the change in technology is limited by the subsidized cost of liquefied petroleum gas, which makes the adoption of this technology difficult in the current state.

[SPA] El intenso cambio de conciencia medioambiental por el cual ha apostado la Unión Europea en los últimos años está provocando una revolución masiva en todos los sectores y, como no podía ser menos, especialmente en el industrial. Durante el presente trabajo de fin de estudios se pretenderá dar una solución coherente a un problema propuesto por dos grandes multinacionales del ámbito energético. El proyecto tiene su origen en el evento organizado por Endesa e Isover Saint-Gobain, “Premios Eficiencia Industrial Isover 2018”, del cual se espera obtener propuestas de diferentes universidades nacionales para el aprovechamiento de parte de la energía derrochada en una de las centrales térmicas de las Islas Canarias. El presente trabajo, por tanto, hace constantes referencias al Trabajo de Fin de Máster “Modelización y simulación de un sistema integrado de recuperación, almacenamiento y valorización energética del calor de los gases de escape de los equipos de potencia de la Central Térmica de las Salinas”, de Enrique Moya Tárraga, a través del cual recibe su sentido completo. El fin al que se pretende llegar es el de realizar un análisis económico de la propuesta de solución para la explotación del calor residual de los equipos generadores de la isla. Dicha solución, a su vez, dependerá de la misma viabilidad técnica, económica y ambiental que se está buscando, generando así un problema retroalimentado. [ENG] The severe environmental awareness for which the European Union has opted in recent years is causing a massive revolution in all business areas, especially in industrial sector. Along this Final Master Project, it will be intended to find a consistent solution to a problem purposed by two energetic multinational companies. The project has its origin in the event organized by Endesa and Isover Saint-Gobain, “Premios Eficiencia Industrial Isover 2018”, through which it’s possible to obtain submissions of different national universities in order to make use of part of the waste heat in one of the thermal power stations in Canary Island. Thus, the present work constantly alludes to Final Master Project “Modelización y simulación de un sistema integrado de recuperación, almacenamiento y valorización energética del calor de los gases de escape de los equipos de potencia de la Central Térmica de las Salinas” (Enrique Moya Tárraga, 2019) through which obtain its full meaning. The aim to achieve is to perform a financial analysis of the solution purposed to profit the waste heat of island diesel and gas generators. This solution will depend on technical, financial and environmental viability, so a feed-back problem is created. ; Escuela Técnica Superior de Ingeniería Industrial ; Universidad Politécnica de Cartagena

En este proyecto se aborda el diseño de un distrito térmico de uso mixto para la generación de energía eléctrica, a base de gas natural, y térmica, con agua helada, cumpliendo con la demanda de un complejo administrativo ubicado en ciudades caribeñas. Es de vital importancia la implementación de este tipo de tecnologías en el mercado actual debido al constante crecimiento de los requerimientos energéticos en estas ciudades y que, a largo plazo, es muy rentable. El enfoque de este proyecto está centrado en el diseño del cuarto de máquinas de un distrito térmico, utilizando tecnologías de cogeneración para la producción de electricidad y frío y, además, realizar su estudio económico. El proceso de diseño consistió primero que todo en una investigación respecto a los distritos térmicos, luego se realizó una búsqueda exhaustiva de fabricantes y equipos. Seguidamente haciendo uso de la información de los fabricantes se procedió a la generación de ideas y alternativas que cumplieran con los requerimientos del proyecto, estas opciones de diseño fueron validadas con la metodología de AHP. La alternativa seleccionada constó de un arreglo de chillers eléctricos, como también de un chiller de absorción haciendo uso de motores a gas natural para la generación eléctrica. Las limitantes encontradas para la realización de este proyecto fueron la falta de información de detalle que nos podían proporcionar algunos fabricantes de los equipos. Lo conseguido por este proyecto fue el diseño exitoso de un distrito térmico cumpliendo las demandas requeridas por el cliente, y generando excedentes de energía que pueden ser usados por otros clientes, así como también para futuras aplicaciones. El análisis financiero del proyecto resultó en un proyecto atractivo para los inversionistas, así como también para los usuarios que demanden la energía. ; This Project addresses the design of a mixed-use district cooling for the generation of electricity, based on natural gas, and thermal, with cold water, meeting the demand of an administrative complex located in Caribbean cities. The implementation of this type of technology in the current market is of vital importance due to the constant growth of energy requirements in these cities and that, in the long term, is very profitable. The focus of this project is centered on the design of the machine room of a thermal district, using cogeneration technologies for the production of electricity and cold, and, in addition, conducting its economic study. The design process consisted first of all in an investigation regarding thermal districts, then an exhaustive search of manufacturers and equipment was carried out. Then, making use of the manufacturers' information, ideas and alternatives were generated that met the project's requirements. These design options were validated with the AHP methodology. The selected alternative consisted of an electric chiller arrangement, as well as an absorption chiller using natural gas engines for electricity generation. The limitations found for carrying out this project were the lack of detailed information that some equipment manufacturers could provide us. What was achieved by this project was the successful design of a thermal district meeting the demands required by the client, and generating surplus energy that can be used by other clients, as well as for future applications. The financial analysis of the project resulted in an attractive project for investors, as well as for users who demand energy.

El objetivo principal del Trabajo Fin de Grado es definir geométricamente y modelar la espuma metálica en la que se embebe el material de cambio de fase estudiado (Phase Change Material, PCM). El PCM constituye el relleno de la matriz metálica porosa que actúa como superficie extendida de un intercambiador de calor para acumulación de energía solar térmica (Thermal Energy Storage, TES). Una vez definida la geometría, se desarrollará una metodología de simulación numérica, que permita evaluar, y caracterizar, el proceso de fusión/solidificación (cambio de fase) del PCM, así como, la mejora que se produce en dicho proceso de carga y descarga de energía, en forma de calor sensible y latente, al aumentar la superficie de transferencia. El Trabajo Fin de Grado incluye realizar una revisión bibliográfica en relación con las estrategias de modelado de la espuma metálica a nivel macroscópico y/o microscópico, en función de sus características geométricas, así como, de los modelos numéricos utilizados por otros investigadores para simular el proceso de fusión/solidificación, teniendo en cuenta efectos como la convección natural, o el cambio de volumen del PCM durante el proceso de cambio de fase. ; Escuela Técnica Superior de Ingeniería Industrial ; Universidad Politécnica de Cartagena
