Abstract

UN METODO PARA CONTROLAR UNA CAJA DE REFRIGERACION DE UN SISTEMA DE REFRIGERACION QUE INCLUYE LOS PASOS DE LOCALIZAR UNA VALVULA DE EXPANSION DE UNA CAJA DE REFRIGERACION, MOVER LA VALVULA DE EXPANSION DE LA CAJA DE REFRIGERACION FUERA DE UNA POSICION PREDETERMINADA, MUESTREAR LECTURAS DE TEMPERATURA DE UNA BOBINA DEL EVAPORADOR DE UNA CAJA DE REFRIGERACION, CALCULAR UN DIFERENCIAL-INTEGRAL-PROPORCIONAL ADAPTATIVO (PID) DE LA TEMPERATURA DE LA BOBINA DEL EVAPORADOR PARA LA REFRIGERACION PARA LA CAJA DE REFRIGERACION, Y MOVER LA VALVULA DE EXPANSION A UNA SEGUNDA POSICION MAS CERCA DE LA POSICION PREDETERMINADA EN BASE AL DIFERENCIAL-INTEGRAL-PROPORCIONAL CALCULADO HASTA QUE LA TEMPERATURA DE LA BOBINA DEL EVAPORADOR PARA LA CAJA DE REFRIGERACION SE ENCUENTRE DENTRO DE UN INTERVALO DE TEMPERATURA PREDETERMINADA.
