Abstract

Descongelación bajo demanda controlada por ordenador para un recinto cerrado enfriado y evaporador a través del cual se hace circular refrigerante. Está previsto un sensor de la temperatura del aire adaptado para generar una señal de la temperatura del aire indicativa de la temperatura del aire dentro del recinto cerrado. Está previsto un sensor de la temperatura del refrigerante adaptado para generar una señal de la temperatura del refrigerante indicativa de su temperatura. Está previsto un controlador programable adaptado para comparar la señal de la temperatura del aire y la señal de la temperatura del refrigerante, para calcular una diferencia entre la temperatura del aire y la del refrigerante. El controlador inicia una rutina de descongelación para eliminar condensado del evaporador si la diferencia entre la temperatura del aire y la del refrigerante es mayor o igual que un umbral de descongelación. Se describen métodos para descongelar un dispositivo refrigerado y detectar la acumulación de condensado.
