Diseño y simulación de un sistema de calentamiento de agua residencial para vivienda unifamiliar de cinco personas, ubicada en la ciudad de Quito-Ecuador, mediante una resistencia eléctrica alimentada por energía fotovoltaica.

Abstract

The intent of this project was developed and simulate the implementation of a residential water heating system, applied to a five-person single-family home in the city of Quito-Ecuador, using an electrical resistance fed by photovoltaic energy. In this way, this system seeks minimize traditional electricity consumption and reduce CO2 emissions. This research was developed throught the analysis and data gathering provided by the Meteonorm software in conjunction with the location of the single-family home. Subsequently, in the desing of the system and operation, the use of monocristalline panels allows exploiting the incidence of radiation during the day. The generation by the photovoltaic modules is stored in lithium batteries, which helps to use the surplus during the day or on the days with less radiation. As far as the selection of the appropriate equipment is concerned, many different calculations were necessary for the required compliances, depending on the medium conditions. The results obtained throught the simulation in the TRNSYS software, allowed us to analyze all the conditions of the photovoltaic system applied to specific climatic conditions generated through the Meteonorm software. The simulation revealed the incident radiation on the surface of the photovoltaic panels and, in turn, made it possible to know the power generated from the arrangement, in order to achieve the needs of the single family home. The climatic conditions and the single-family location helped to achieve satisfactory result in power generation, being adequate to the needs of water heating.
