Design of a hybrid solar collector with a flat plate solar collector and induction heating: evaluation and modelling with principal components regression

Food drying is one of the main food preservation processes, which are supplied with electrical energy (EE). Recently, the EE has had constant increases in its costs, prompting the integration of renewable energy sources for these processes. Therefore, the objective of this research was to design, build and model a hybrid solar collector (HSC-IH) for drying food, made up of solar energy (SE) through a solar collector and EE by means of induction heating. (IH), this work prioritizes the incorporation of an auxiliary heating system for the solar collectors, minimizing temperature variability and increasing its heat capacity, the HSC-IH has a collection surface of 1 m2, adjustable flow of 0.3 - 4 CMM and maxim of 80 ° C, the prediction model developed with PCR, to determine the outlet temperature (OT) provided by the HSC-IH with only the use of solar energy and to estimate the energy provided by the EE with the IH, the final model it has an R2 of 0.934 and can be used to understand the OT of HSC-IH.
