| Sumario: | In this doctoral thesis, the mathematical modeling of thermal zones is used to evaluate the ability of the control in sliding modes, to regulate the internal temperature of a case study. The grouped parameters technique is used to represent the closed spaces, which, when complemented with experimental measurements and optimization algorithms, allowed the construction of a simulator to reproduce the conditions of the model studied with an accuracy of more than 97 %, which allowed studying the system in general while introducing disturbances or variations in the model parameters. Initially, reduced-scale models were used to characterize the thermal insulating effect of the Thermo Skold solution on the internal temperature. The impact of the painting on each one of the heat transfer parameters was studied, which allowed us to understand the savings and results obtained experimentally. Subsequently, the reduced scale models were used to evaluate the control technique in sliding modes, so the effectiveness of the technique was modeled, simulated and veri ed experimentally to maintain a fixed reference temperature, with an error of less than 2 %. In the final stage of the thesis, a geodesic dome was used as a case study, which was modeled with an electrical circuit proposed for its speci c characteristics. Experimental measurements of the thermal conditions of the geodesic dome were made, with which the simulator was adjusted using the Pattern Search optimization algorithm. Thanks to the simulator developed, the thermal comfort conditions and the cooling needs of the dome were studied, considering different situations and internal loads by occupants and cooling systems. |
