Abstract

"SISTEMA PARA AJUSTAR A TEMPERATURA EM UM APARELHO DE REFRIGERAçãO". Compreendendo: pelo menos um compartimento de refrigeração (RC) fechado por uma porta frontal (11); um compressor (20 ); adicionalmente pelo menos um ventilador (50); um meio sensor de temperatura (40); e um meio de controle (30) construído para ativar e desativar o compressor (20) e o ventilador (50) quando o interior do compartimento de refrigeração (RC ) alcançar temperaturas de ativação e de desativação, respectivamente. O sistema de ajuste em questão compreende um meio detector de abertura de porta (60) operativamente associado ao meio de controle (30) que é projetado para reduzir a temperatura de desativação do compressor (20) e/ou do ventilador (50) quando a temperatura do compartimento de refrigeração (RC), detectada pelo meio sensor de temperatura (40), for maior que a temperatura de ativação do compressor (20) e/ou do ventilador (50) no momento do fechamento da porta frontal (11) ou em pelo menos mais um momento subseqüente, apresentando um retardo em relação ao momento anterior, de modo a minimizar as variações de temperatura do alimento armazenado no compartimento de refrigeração (RC).
