Abstract

1 / 1 resumo “mã‰todo para controlar a velocidade do compressor centrã�fugo, e, sistema de controleâ€� a presente invenã§ã£o se refere a um mã©todo e sistema de controle para controlar a velocidade de um compressor centrã­fugo que opera dentro de um processo de adsorã§ã£o de oscilaã§ã£o de pressã£o de vã¡cuo para evitar uma operaã§ã£o em que sobretensã£o pode ocorrer e diretamente acionado por um motor elã©trico que por sua vez ã© controlado por um acionamento de frequãªncia variã¡vel. de acordo com a presente invenã§ã£o uma velocidade ã³tima para a operaã§ã£o do compressor ã© determinado em que o compressor vai operar ao longo de uma eficiãªncia de pico que opera a linha de um mapa de compressor do mesmo. esta velocidade ã© ajustada atravã©s de um multiplicador de velocidade de retorno da alimentaã§ã£o quando o fluxo ou outro parã¢metro que se refere ao fluxo atravã©s do compressor estã¡ abaixo de um mã­nimo e um multiplicador de prã©-alimentaã§ã£o durante a evacuaã§ã£o e a evacuaã§ã£o com as etapas de purga que multiplica o multiplicador de retorno de alimentaã§ã£o para aumentar a velocidade do compressor e desta forma evitar a sobretensã£o.
