Abstract

"DISPOSITIVO AUTO-REGULáVEL PARA CONTROLE DE APARELHOS DE REFRIGERAçãO". Trata-se de um dispositivo auto-regulável para controle de aparelhos de refrigeração, tais como refrigeradores ou congeladores ("freezers"), preferencialmente demésticos, que compreendem um circuito de refrigeração com um compressor (2), um evaporador (3), um condensador (4) e um dispositivo de controle (6, 7) do compressor (2) com um sensor de temperatura (5) disposto em contato com o evaporador, nos quais o referido dispositivo (6, 7) de controle do compressor (2) é um dispositivo microprocessador que registra e processa a temperatura do evaporador e pelo menos um dos seguintes dois parâmetros: o tempo de funcionamento do compressor e o tempo durante o qual o compressor fica inativo e compara o(s) referido(s) tempo(s) com um ou mais valores tabuladores, para assegurar que o tempo de estado desligado (tr) do compressor (2) alcance e mantenha, mediante auto-regulagem, um valor tabular previamente determinado constante (tr1).
