Abstract

LA COMPOSICION DE UN REFRIGERANTE EN UN CICLO DE REFRIGERACION SE DETECTA, DE MANERA QUE EL CICLO DE REFRIGERACION ES CONTROLADO POR UN METODO DE CONTROL DE ACUERDO CON LA COMPOSICION DETECTADA. UN VALOR DE OBJETIVO DE CONTROL SE ESTABLECE DE ACUERDO CON LA COMPOSICION DETECTADA, Y CUANDO LA COMPOSICION ES VARIADA, EL OBJETIVO DE CONTROL ES CAMBIADO DE ACUERDO CON LA VARIACION. COMO RESULTADO, INCLUSO CUANDO LA COMPOSICION REFRIGERANTE ES VARIADA, EL CICLO DE REFRIGERACION PUEDE SER OPERADO ESTABLEMENTE. EL CICLO DE REFRIGERACION UTILIZA UN REFRIGERANTE NO AZEOTROPICO, Y COMPRENDE UN DISPOSITIVO PARA DETECTAR LA COMPOSICION DE UN REFRIGERANTE NO AZEOTROPICO; UN DISPOSITIVO PARA DETECTAR EL ESTADO OPERATIVO DEL CICLO DE REFRIGERACION, POR EJEMPLO VALORES DE ESTADO A CONTROLAR, TALES COMO TEMPERATURA O PRESION; UN APARATO DE CONTROL DE CALCULOS PARA ACEPTAR LA COMPOSICION, LA TEMPERATURA O LA PRESION, O SIMILARES DETECTADOS POR EL DISPOSITIVO DE DETECCION COMO UN DATOS DE ENTRADA Y PARA LLEVAR A CABO UNA CONVERSION DE SEÑAL, UN CONTROL DE CALCULO PARA OBJETIVOS DE CONTROLO SIMILARES; Y UN APARATO DE TRANSMISION PARA CONDUCIR LOS COMPONENTES DEL CICLO DE REFRIGERACION , ASI COMO UN COMPRESOR O UN APARATO DE REDUCCION DE PRESION DE REFRIGERANTE.
