Abstract

UN SISTEMA DE SUPERVISION PARA UN SISTEMA DE CALEFACCION O REFRIGERACION INCLUYE UNA RED NEURAL PARA COMPUTAR EL ESTADO DE UNA O MAS VALVULAS DE EXPANSION DENTRO DEL SISTEMA. LA RED NEURAL ES ENTRENADA PARA QUE APRENDA DETERMINADAS CARACTERISTICAS DEL SISTEMA DE CALEFACCION O REFRIGERACION DURANTE EL MODO DE DESARROLLO DE LA OPERACION. LA RED NEURAL ASI ENTRENADA COMPUTA OPORTUNAMENTE EL ESTADO DE UNA O MAS VALVULAS DE EXPANSION DURANTE EL MODO DE TIEMPO DE EJECUCION DE LA OPERACION. LA INFORMACION RESPECTO AL ESTADO DE UNA O MAS VALVULAS DE EXPANSION ESTA DISPONIBLE PARA EVALUACION EN TIEMPO REAL DURANTE EL MODO DE TIEMPO DE EJECUCION DE LA OPERACION.
