Abstract

EN UN SISTEMA DE REFRIGERACION MULTI-COMPRESOR DE ALIMENTACION LINEAL UTILIZABLE POR DISTINTOS USUARIOS, QUE COMPRENDE UNA UNIDAD CENTRAL DE REFRIGERACION SUMINISTRADA CON UNA PLURALIDAD DE UNIDADES COMPRESORAS A MOTOR (11, 12, 13) DE DISTINTA POTENCIA DE UNIDAD DISPUESTAS EN PARALELO ENTRE UN COLECTOR DE SUCCION (14) Y UN COLECTOR DE DESCARGA (15), SE SUMINISTRAN UN INVERSOR (17) Y UN SISTEMA LOGICO PROGRAMABLE O DEDICADO ASOCIADO (16), QUE CONTROLA SELECTIVAMENTE LA ACTIVACION DE LAS UNIDADES INDIVIDUALES COMPRESORAS A MOTOR (11, 12, 13) PARA OBTENER UNA POTENCIA DE INCREMENTO Y/O DESCENSO LINEALMENTE, Y LA MANTIENE IGUAL A LA REQUERIDA POR LOS USUARIOS. PREFERIBLEMENTE, LAS UNIDADES COMPRESORAS A MOTOR (11, 12, 13) SON TRES EN NUMERO, DE LAS QUE DOS (11, 12) SON DE ALTA POTENCIA Y UNA (13) ES DE BAJA POTENCIA.
