Abstract

SISTEMA DE CONTROL PARA BOMBA DE CALOR QUE CUENTA CON UNA DISPOSICION DE SENSOR DESACOPLADO, EN EL CUAL SE DOSIFICA EL REFRIGERANTE A TRAVES DE LA VALVULA DE EXPANSION BASANDOSE EN MEDICIONES DE LA TEMPERATURA DE DESCARGA DEL COMPRESOR Y DE LA TEMPERATURA DEL AIRE AMBIENTAL. EL SISTEMA DE CONTROL BASADO EN MICROORDENADOR SELECCIONA EL APROPIADO AJUSTE DE LA VALVULA DE MOTOR PROGRESIVO PARA CONSEGUIR EL RENDIMIENTO OPTIMO. LAS MEDICIONES DE TEMPERATURA UTILIZADAS EN EL SISTEMA DE CONTROL SE DESACOPLAN DE FLUCTUACIONES DEBIDAS AL DESPLAZAMIENTO DEL PUNTO DE DESECACION DEL REFRIGERANTE. ESTO PERMITE QUE EL SISTEMA SEA HECHO FUNCIONAR A TEMPERATURAS DE SUPERCALOR MUCHO MENORES QUE LAS HASTA AHORA CONSEGUIDAS, PRODUCIENDO UN RENDIMIENTO MEJORADO Y UNA DURACION MAYOR DE LOS COMPONENTES.
