Abstract
El presente informe entrega los resultados de las alternativas
trigenerativas y convencionales con GN para satisfacer las demandas energeticas
de un Supermercado, ubicado en la comuna de Quillota. Para esto se han
utilizando herramientas técnicas y econOmicas con el fin de evaluar la factibilidad
de implementar un sistema trigenerativo.
Para introducirnos en las alternativas trigenerativas, se presentan
los esquemas de cada una de ellas, y métodos de selecciôn en funciOn de la
relaciôn entre las potencias térmicas y eléctricas. Estas Ultimas, estudiadas de
los registros estadisticos de consumo de electricidad, y cálculos térmicos, segOn
Manual Carrier.
Por existir la posibilidad de asociar un estanque aislado a la
máquina generadora de agua frIa para climatizar, se modela matemáticamente,
mediante polinomio de Lagrange, la relación entre el caudal generado y el
volumen del estanque, parametrizando el costo del conjunto en funciOn de este
valor.
Para cada alternativa trigenerativa se ejecutO un balance
energetico del generador eléctrico, logrando seleccionar la potencia de la máquina
de absorciôn de fuego indirecto, a partir de la potencia térmica recuperada.
Finalmente, la decision de ejecutar un proyecto trigenerativo, es
dependiente del indicador econOmico CAUE, utilizado para comparar y definir la
rnwr alernativa desde el punto de vista de costos globales, no descartando el
consumir energia eléctrica desde la red, y utilizar una maquina de absorciOn de
fuego directo a GN (alternativa convencional).
In this report, the trigenerative and conventional with NG alternatives have been studied to satisfy the energetic demand of a Supermarket located in teh commune of Quillota. For this, technical and economical tools have been used with the purpose of evaluating the feasibility of implementing a trigenerative system. In order to enter into the trigenerative alternatives, the schemes of each one of them and selection method in function of the relationship among the thermal and electric powers are introduced. These last ones have been studied from the statixtical records of electricity consumption and thermal calculations, according to the Carrier Catalogue. Because there is the posibility of associating an isolated vessel to the cold water-generator machine to acclimatize, the relationship among the generated flow and the vessel volume is mathematically modelled through the Lagrange polynomial, limiting the group cost in function of this value. For each trigenerative alternative, an energetic balance of the electrical generator was performed, beind able to select the machine's indirect fire absoption power, from the recovered thermal power. Finally, the decision of executing a trigenerative project depends on the economical indicator CAUE, used to compare and define the best alternative from the point of view of global costs, not discarding the consuming of electrical power from the network, and using a direct fire absortion machine to NG (conventional alternative).
