Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE REFRIGERACION PARA UN MOTOR (5) SOBREALIMENTADO CON UN CIRCUITO DE ALTA TEMPERATURA Y OTRO DE BAJA TEMPERATURA, EN DONDE SE HAN PREVISTO DOS REFRIGERANTES DE AIRE DE SOBREALIMENTACION POR LOS QUE CIRCULAN AGENTES REFRIGERANTE DE DIFERENTES NIVELES DE TEMPERATURA PARA LA REFRIGERACION DEL AIRE DE SOBREALIMENTACION EN DOS ETAPAS. EL CIRCUITO DE ALTA TEMPERATURA SE COMPONE DE UN REFRIGERANTE DE RETORNO (3) DE ALTA TEMPERATURA CONECTADO EN SERIE CON EL MOTOR (5). CON ELLO PUEDE SER MANTENIDA BAJA LA CANTIDAD TOTAL DE AGENTE REFRIGERANTE Y PUEDE SER ALCANZADO UN ALTO GRADO DE INTERCAMBIO DE CALOR EN UNA DISPOSICION DE TUBERIAS MAS SENCILLO. LA CANTIDAD DE REFRIGERANTE QUE ARRASTRA EL CIRCUITO CONTIGUO ES MEZCLADA CON LA CORRIENTE DE AGENTE REFRIGERANTE QUE CIRCULA EN EL MOTOR (5), Y LA CORRIENTE TOTAL DE AGENTE REFRIGERANTE QUE PROCEDE DEL MOTOR (5) FINALMENTE ES CONDUCIDA HACIA EL REFRIGERANTE DE RETORNO (3) DE ALTA TEMPERATURA. LA CANTIDAD DE REFRIGERANTE NECESARIA EN EL RANAL CONTIGUO ES DESVIADA DEL AGENTE REFRIGERANTE QUE CIRCULA AL MOTOR (5). ESTE CAUDAL QUE CIRCULA DEL REFRIGERANTE DE RETORNO (3) DE ALTA TEMPERATURA SE MEZCLA CON EL CAUDAL DE REFRIGERANTE PROCEDENTE DEL REFRIGERANTE DE AIRE (1) DE ALTA TEMPERATURA DEL AIRE DE BARRIDO Y DEL REFRIGERANTE (22) DE BAJA TEMPERATURA. EL CIRCUITO DE BAJA TEMPERATURA SE COMPONE DE UN REFRIGERANTE DE RETORNO (4) CONECTADO EN SERIE CON EL REFRIGERANTE DE AIRE DE BARRIDO (2) DE BAJA TEMPERATURA.
