Abstract
LA INVENCION SE REFIERE A UN APARATO DE REFRIGERACION O CONGELACION, CON PREFERENCIA DE TIPO DOMESTICO, EQUIPADO CON AL MENOS UN COMPRESOR RECIPROCO HERMETICO, PROVISTO CON UN MOTOR DE ACCIONAMIENTO ELECTRICO DE TIPO SIN ESCOBILLAS Y UNA DISPOSICION DE CONTROL DE FRECUENCIA ELECTRONICA ADAPTADA PARA OPERAR EL INDICADO MOTOR EN UNA PLURALIDAD DE RPM DIFERENTES PREVIAMENTE SELECCIONADAS. EL INDICADO COMPRESOR ESTA PROVISTO CON UNA CARACTERISTICA DE PROTECCION CONSTITUIDA POR MEDIO DE UNA APLICACION DE RPM MINIMAS PRESELECCIONABLES (VMIN) DEL INDICADO MOTOR, POR DEBAJO DE LA CUAL LA DISPOSICION DE CONTROL INDICADO CORTA LA OPERACION DEL MOTOR. ADEMAS LA DISPOSICION DE CONTROL INDICADA SE ADAPTA PARA SELECCIONAR LAS RPM DEL MOTOR (VMAX) QUE ES DIFERENTE DE CUALQUIER RPM PRESELECCIONABLE CUANDO LA DISPOSICION DE CONTROL SE SUMINISTRA CON UN COMANDO EXTERNO O UNA COMBINACION PARTICULAR DE SEÑALES QUE SON INDICATIVAS DE LA OPERACION DEL APARATO DE REFRIGERACION.
