Abstract

EN UNA VALVULA DE EXPANSION (10) PARA CONTROLAR EL CAUDAL UNITARIO DE UN REFRIGERANTE ADMINISTRADO A UN EVAPORADOR (1) DE UN SISTEMA DE REFRIGERACION, SE DISPONE UNA CAMARA SENSIBLE A LA TEMPERATURA (30) PARA ADVERTIR LA TEMPERATURA DEL REFRIGERANTE DE RETORNO DE DICHO EVAPORADOR (1) Y PARA ACCIONAR UN MECANISMO DE VALVULA (20) PARA REGULAR EL FLUJO DE REFRIGERANTE ADMINISTRADO A DICHO EVAPORADOR (1). UN SISTEMA DE ABSORCION (35) DISPUESTO DENTRO DE LA CAMARA SENSIBLE A LA TEMPERATURA (301) PARA ABSORBER UNA PARTE LICUADA DE UNA CARGA DE GAS DENTRO DE DICHA CAMARA (30) PARA MANTENER DICHA PARTE LICUADA LEJOS DE LAS PARTES DE PARED CALIENTES DENTRO DE LA CAMARA (30). ADEMAS, O COMO ALTERNATIVA, DICHA CAMARA (30) ESTA SEPARADA DE UN PASO DE RETORNO (12) DE DICHO REFRIGERANTE POR UN SISTEMA DE RETRASO DE TRANSFERENCIA TERMAL PARA RETRASAR LA TRASFERENCIA TERMAL DE UNA CAMBIO DE TEMPERATURA DEL REFRIGERANTE A LA CARGA DE OBTURACION DENTRO DE LA CAMARA SENSIBLE A LA TEMPERATURA (30). DICHO SISTEMA DE RETRASO DE TRANSFERENCIA TERMAL PUEDE CONVERTIRSE EN RESTRICTOR DE FLUJO (28A,38,48) PARA SUPRIMIR UN FLUJO EXCESIVO ENTRE DICHA CAMARA (30) Y DICHO PASO DE RETORNO (12) DEL REFRIGERANTE.
