Abstract

EN UN PROCESO PARA LA COLOCACION, EL CONTROL Y LA INSPECCION DEL NIVEL DE UNE EVAPORADOR REFRIGERANTE (3) UBICADO EN UN CIRCUITO CERRADO DE UN FRIGORIFICO (1) Y EVAPORANDO UN FLUJO DE MASA DE REFRIGERANTE (4) PARA FORMAR UN GAS DE ASPIRACION SUBSTANCIALMENTE SECO, UNA UNIDAD DE MEDIDA (11) CALENTABLE SE INTRODUCE EN LA LINEA DE IMPULSION DEL GAS (71) EN LA DIRECCION DE CIRCULACION DEL FLUJO DEL EVAPORADOR REFRIGERANTE (3). EL GAS DE ASPIRACION CIRCULA ALREDEDOR DE LA UNIDAD DE MEDIDA (11). SE CALIENTA A UNA TEMPERATURA SUPERIOR A LA DEL GAS DE ASPIRACION. LA COLISION DE GOTAS DE REFRIGERANTE SOBRE LA UNIDAD DE MEDIDA (11) SE DETERMINA POR LA MEDIDA DE LA ENERGIA NECESARIA PARA EVAPORARLAS GOTAS DEL LIQUIDO. LA SEÑAL DE MEDIDA PUEDE SER EVALUADA DE MANERA FIABLE SI SE COMPARA CON UNA SEÑAL BASE OBTENIDA DE UNA PRIMERA SEÑAL PARCIAL QUE SURGE DEL RUIDO ELECTRONICO E UNA UNIDA DE MEDIDA Y EVALUACION (93) USADA PARA IMPLEMENTAR EL PROCESO Y DE UNA SEGUNDA SEÑAL PARCIAL QUE SURGE DEL FLUJO DE GAS DE ASPIRACION QUE CIRCULA POR LA UNIDAD DE MEDIDA (11), POR LO QUE LA DIFERENCIA ENTRE LA MEDIDA Y LAS SEÑALES BASICAS ES HALLADA Y COMPARADA CON UN VALOR AJUSTABLE DE REFERENCIA QUE SE COLOCA EN EL NIVEL DE HUMEDAD DEL GAS DE POTENCIA POR ENCIMA DEL CUAL EL GAS DE ASPIRACION PUEDE SER CONSIDERADO COMO VAPOR O HUMEDO.
