Abstract
UN SISTEMA DE REFRIGERACION MULTIETAPA UNICO PARA MULTIPLES VITRINAS O CAJAS EXHIBIDORAS DE PRODUCTO EN EL CUAL CADA VITRINA TIENE UN COMPRESOR DE REFUERZO DE ETAPA BAJA DISPUESTO EN ELLA. CADA COMPRESOR DE REFUERZO COMPRIME REFRIGERANTE RECIBIDO DEL EVAPORADOR EXISTENTE EN SU VITRINA Y ALIMENTA EL MISMO A UNA BATERIA DE ETAPA ALTA DISPUESTA EN UN CUARTO DE EQUIPO SITUADO A DISTANCIA. ESTA PREVISTO UN SUBENFRIADOR MECANICO PARA CONTROLAR LA TEMPERATURA DEL REFRIGERANTE LIQUIDO, Y SE CREA UN SISTEMA DE LUBRICACION MEJORADO PARA EQUILIBRAR LA DISTRIBUCION DE LUBRICANTE A TRAVES DE TODO EL SISTEMA. TAMBIEN SE MUESTRAN VARIAS MODIFICACIONES DEL SISTEMA.
