Abstract

Metodo para controlar un circuito (2) de refrigeracion que opera intermitente y supercriticamente que comprende un compresor (4), un termointercambiador (10) de supresion de calor y una valvula (12) de control y un control (16), el metodo comprende las siguientes etapas: (a) modo subcritico, que controla la valvula (12) de control de tal manera que se mantiene una "presion supercritica" predeterminada que asegura un subenfriamiento predeterminado del refrigerante liquido en la salida (14) del termointercambiador (10) de supresion de calor; (b) un modo supercritico, que controla el control; valvula (12) de tal manera que se mantiene una "presion supercritica" predeterminada la cual se optimiza para eficiencia optima del refrigerante supercritico en la salida (14) del termointercambiador (10) de supresion de calor; y (c) un modo de limite en una region cerca del punto critico, que controla la valvula (12) de control dependiendo de una " presion de continuidad" la cual se determina en la base de la "presion subcritica" y la "presion supercritica" predeterminadas de las etapas (a) y (b).
