Abstract
"COMPRESSOR DE PARAFUSO DE MULTI-ROTOR". Um compressor de parafuso de multi-rotor inclui um alojamento de compressor definindo pelo menos três seções de alojamento de rotor paralelas, cada seção de alojamento de rotor contendo um rotor, e rotores adjacentes definindo pelo menos dois pares de compressores, o alojamento ademais incluindo um orifício de sucção e um orifício de descarga para cada um dos pares de compressores, e ademais incluindo pelo menos dois orifícios adicionais selecionados do grupo que consiste em primeiros orifícios de lóbulo fechados, últimos orifícios de lóbulo fechados, e orifícios economizadores, em que pelo menos um dos orifícios adicionais é comunicado com um primeiro par dos pelo menos dois pares, e outros dos orifícios adicionais é comunicado com um segundo par dos pelo menos dois pares, por meio de que interação entre os orifícios adicionais é reduzida. De acordo com um aspecto adicional da invenção, um primeiro par de compressores é comunicado com um orifício economizador e tem um primeiro orifício de descarga, e um segundo par de compressores não é comunicado com o orifício economizador e tem um segundo orifício de descarga, e o primeiro e segundo orifícios de descarga são seletivamente dimensionados assim para prover o primeiro orifício de descarga com uma relação de índice de volume mais baixa (Vi) do que o segundo orifício de descarga. De acordo com um aspecto adicional da invenção, um primeiro par de compressores é comunicado com um orifício economizador e tem um primeiro orifício de descarga, e um segundo par de compressores não é comunicado com o orifício economizador e tem um segundo orifício de descarga, e o primeiro e segundo orifícios de descarga são seletivamente dimensionados assim para prover o primeiro orifício de descarga com uma relação de índice de volume mais baixa (Vi) do que o segundo orifício de descarga.
