Economia de energia e redução do pico da curva de demanda para consumidores de baixa renda por agregação de energia solar térmica (original) (raw)

The main objective of the present work is to establish a methodology capable of assessing, through the use of a compact thermosyphon solar hot water heating system, the energy saving and electric energy peak reduction potential during the peak hours for a group of low-income residential consumers. In order to quantify these potentials, a total of 90 lowincome consumers were chosen to have their electric energy consumption monitored. Analysis of the collected data rendered relevant information for energy conservation policies, such as the hourly distribution of hot water consumption, the fraction of the electric energy consumption used for water heating, the average contribution of electric showerheads to the peak demand, and the estimated solar fraction for the group of consumers. The validation of the TRNSYS (Transient System Simulation Program) computational code for a thermosyphon solar water heating system is undertaken. The multi-objective economic optimization of constructive ...
