Abstract

trata-se, dentre outras coisas, de um método e de um aparelho para controle de um dispositivo de refrigeração. o dispositivo de refrigeração compreende um circuito no qual um fluido refrigerante é circulado em uma passagem de fluido em que o circuito compreende um compressor e um condensador fornecido a jusante do compressor. um dispositivo de expansão de fluido é fornecido a jusante do condensador e um evaporador é fornecido entre o dispositivo de expansão de fluido e o compressor. o circuito compreende adicionalmente uma válvula fornecida na passagem de fluido entre o condensador e o dispositivo de expansão de fluido. o método compreende, durante um ciclo de atividade do compressor, controlar a abertura de válvula a fim de fornecer um fluxo de massa fluida variável do fluido refrigerante circulado no circuito em que a abertura de válvula é controlada de modo a diminuir durante o ciclo de atividade do compressor.
