Abstract
"SISTEMA DE CONTROLE DE TEMPERATURA EM UM APARELHO DE REFRIGERAçãO". Compreendendo: um gabinete (10) definindo pelo menos um compartimento de refrigeração (RC) fechado por uma porta (11); um compressor (20); e um meio de controle (30) provido de um meio temporizador (31) e construido para ativar e desativar o compressor (20) quando o interior do compartimento de refrigeração (RC) alcançar temperaturas de ativação e de desativação, respectivamente. O sistema de controle compreende um meio sensor de temperatura ambiente (50) e um meio de detector de abertura de porta (60), operativamente conectados ao meio de controle (30), este último sendo projetado para ajustar as temperaturas de ativação e de desativação do compressor (20) em função da temperatura ambiente externa ao gabinete (10) e do padrão de abertura da porta (11), de modo a minimizar as variações da temperatura do alimento armazenado no compartimento de refrigeração (RC)."TEMPERATURE CONTROL SYSTEM IN A COOLING APPLIANCE". Comprising: an enclosure (10) defining at least one refrigeration compartment (RC) enclosed by a door (11); a compressor (20); and a control means (30) provided with a timer means (31) and constructed to activate and deactivate the compressor (20) when the interior of the refrigeration compartment (RC) reaches on and off temperatures, respectively. The control system comprises an ambient temperature sensing means (50) and a door opening detector means (60) operatively connected to the control means (30), the latter being designed to adjust on and off temperatures compressor (20) as a function of the ambient temperature outside the cabinet (10) and the door opening pattern (11) so as to minimize variations in the temperature of the food stored in the refrigeration compartment (RC).
