Evaluación de diferentes configuraciones para maximizar la captura energética de sistemas solares en Quito.

Abstract

New energy technologies are being used due to the energy transition that must take place on the planet to combat climate change. One such renewable technology is the use of solar radiation to heat water for sanitary use. Using the National Renewable Energy Laboratory's System Advisor Model Renewable Energy Laboratory's System Advisor Model, the goal is to establish a guideline where the energy capture is stable throughout the year and analyze several cases of consumption at different times proposed to have a constant production of domestic hot water during the year in the city of Quito-Ecuador.

A flat-plate solar collector is considered for the simulation data with an effective area of 2m^2 was used to analyze different theoretical consumption patterns, water heating and the energy captured throughout the year.

Finally, the results obtained are that the best orientation to obtain the best amount of absorbed energy is at an azimuth of 90º and an inclination of 20º, obtaining an average maximum temperature of 35.34ºC and the greatest amount of radiation that hits the collector is at an azimuth of 0º between June and August. Also, the best orientation for the use of water in the schedules 6h00 to 8h00, 11h00 to 13h00 and 18h00 to 20h00 is in the 90º azimuth with a 20º inclination for the first two consumption patterns and the 90º azimuth with a 20º inclination for the first two consumption patterns and the 270º azimuth with 20º inclination for the last consumption pattern.
