Abstract

UN APARATO DE CONTROL DE FLUJO DE MASA Y METODO PARA SU UTILIZACION EN COMBINACION CON UN SISTEMA DE TRANSFERENCIA POR CALOR (10) QUE TIENE UN COMPRESOR (16), UN CONDENSADOR (18), UNA VALVULA DE EXPANSION (22), UN EVAPORADOR (14) Y UN FLUIDO MOTOR (12) EN UN CIRCUITO DE FLUIDO. EL FLUJO DE MASA ES CONTROLADO UTILIZANDO UN SENSOR DE CALIDAD (150) PARA EL FLUIDO MOTOR QUE SALE DEL EVAPORADOR (14), Y UN SENSOR DE PRESION LATERAL ELEVADA (50). UN CIRCUITO DE CONTROL (60,160) MONITORIZA EL SENSOR DE CALIDAD (150) Y EL SENSOR DE PRESION LATERAL ELEVADA (50) Y CONTROLA LAS OPERACIONES DEL COMPRESOR (16), DEL VENTILADOR DEL CONDENSADOR (20) Y DE LA VALVULA (22), EN RESPUESTA A LOS MISMOS. UN MODO DE REDUCCION DE FLUJO ES UTILIZADO PARA REDUCIR LA PRESION LATERAL ELEVADA EN LA ENTRADA DE LA VALVULA SIN UN EXCESIVO CICLAJE DEL COMPRESOR, CAMBIANDO LA PROGRAMACION DEL SENSOR DE CALIDAD CUANDO LA PRESION LATERAL ELEVADA EXCEDE LA PRESION DE ENCENDIDO DEL VENTILADOR DEL CONDENSADOR, PERO ES MENOR QUE LAPRESION DE DESENLACE DEL COMPRESOR.
