Comparación de dos técnicas de control en un sistema forzado de calentamiento de agua solar

study on the performance of a forced solar heating system in which a comparative analysis of two control strategies, including the classic on- off control and PID control is performed is presented. From the experimental results, it was found that the two control strategies show a similar behavior in the solar heating system forced an approximate settling time of 60min and over- elongation 2°C for the two control strategies. Furthermore, the maximum temperature in the storage tank was 46°C and the maximum efficiency of flat plate collector were 76.7% given that this efficiency is the ratio of the energy of the radiation on the collector and the energy used to heat water. The efficiency obtained is a fact well accepted because the business efficiencies of flat plate collectors are approximately 70%.
