Diseño de un sistema solar térmico para la sustitución de consumo de combustibles fósiles para la producción de derivados lácteos de la Quesera Santa Marta – San Juan – Chimborazo.

Abstract

The present research work had the aim to design a thermal solar system for the substitution of fossil fuels for the production of dairy products of Santa Marta Cheese dish in San Juan Parish, of Chimborazo Province , it was realized the selection of flat plane solar collectors, function to calculate the training area needed to pasteurize 500 L/d being 103.,62m2, the same solar panels were chosen for having a greater solar radiation collection area, use thermic oil as a heat transfer fluid without need to have an auxiliary power generation device, as extra help to the system. By mass and energy balance that dimensions a heat exchanger in counter flow of transfer area of 0,15m2, to change phase to steam water for delivery to jacket type pasteurizer. The technical validation was done through simulation in the software SolidWorks and drawings in third dimension, observing the correct functioning of the solar thermal system in real time, throwing operation data as thermal oil temperature of 180ºC, at the exit of the collectors and the steam temperature of the entrance to the pasteurizer 120ºC, to perform pasteurization with 6 hours a day of solar radiation use. Concluding that this thermal solar system helps the environment, since it substitutes a hundred years for the use of fuel of fossil type avoiding the pollution of the planet. It was recommended to have the existing cauldron as securityif there is any fault in the solar thermal system.
