Abstract

SISTEMA ADAPTABLE DE DESCONGELACION DE INTERCAMBIADOR DE CALOR, POR EJEMPLO UN EVAPORADOR DE BOMBA DE CALOR, QUE INCORPORA UN CONTROLADOR DEL SISTEMA QUE ADAPTA LOS INTERVALOS ENTRE LOS CICLOS DE DESCONGELADO A LAS CONDICIONES PREVALECIENTES PARA MEJORAR LA EFICACIA GLOBAL. EL TIEMPO QUE LLEVA EL COMPLETAR UN CICLO DE DESCONGELACION SE MIDE Y COMPARA CON EL TIEMPO EMPLEADO POR EL CICLO DE DESCONGELACION ANTERIOR PARA DETERMINAR SI HAY QUE AUMENTAR O DISMINUIR EL INTERVALO ENTRE LOS MUESTREOS DEL PARAMETRO OPERATIVO UTILIZADO PARA DETERMINAR SI ES NECESARIO UN CICLO DE DESCONGELACION.
