Abstract

LA VIA NORMAL DEL FLUJO DE ACEITE/REFRIGERANTE REGENERADO DESDE EL REFRIGERADOR (12) SE CAMBIA DURANTE PERIODOS DE OPERACION DE CARGA BAJA DE MANERA QUE LA MEZCLA ACEITE/REFRIGERANTE FLUYE DIRECTAMENTE DEL REFRIGERADOR (12) AL EYECTOR (40) EN VEZ DE POR LA VIA DE PASO DE CAJA DE SUCCION NORMAL. ESTO SE CONSIGUE MEDIANTE SISTEMAS DE VALVULAS (27,28) SENSIBLES TANTO A UNA DIFERENCIA DE PRESION COMO A UNA POSICION DE ALABES DE GUIA, SIENDO AMBOS INDICADORES DE CONDICION DE CARGA.
