Abstract

Un método perfeccionado de detectar la acumulación de hielo en el serpentín de un sistema de refrigeración por compresión de vapor vigilando el funcionamiento de un motor de compresor, caracterizado por las operaciones de: vigilar un parámetro operativo del motor del compresor en respuesta al régimen de transmisión de calor de un serpentín conectado operativamente a él y producir, a partir de dicha vigilancia, una señal de salida eléctrica continua que indica la variación del parámetro operativo durante el funcionamiento cíclico del motor del compresor; generar, a partir de dicho parámetro vigilado, una señal de referencia eléctrica que indique el funcionamiento del motor del compresor durante la operación libre de hielo de serpentín; comparar dicha señal de salida eléctrica producida durante el funcionamiento cíclico con dicha señal de referencia y producir una señal de mando en respuesta a una variación predeterminada entre dichas señales de salida y de referencia; y acoplar dicha señal de mando a medios de descongelación activables, al recibirse dicha señal de mando, para lograr la descongelación de dicho serpentín.
