Abstract

"MáQUINAS DE DESLOCAMENTO DE MúLTIPLOS ROTORES E DE DESLOCAMENTO POSITIVO, E, APARELHO DE REFRIGERAçãO DE COMPRESSãO/EXPANSãO DE UM úNICO FLUIDO" Uma máquina de deslocamento positivo que tem um conjunto de rotores de engrenamento paralelo, empregados em um sistema de refrigeração de compressão/expansão e recebe uma entrada de refrigerante fluido a partir de um condensador e expande o fluido em uma primeira zona e força substancialmente todo o fluido na primeira zona até um evaporador. O fluido restante a partir da primeira zona da máquina é então comprimido em uma segunda zona adjacente da máquina para formar um vapor de alta pressão, o qual é então encaminhado de volta para o condensador. A máquina de deslocamento positivo inclui um primeiro rotor que tem uma pluralidade de lobos helicoidais colocados ao redor de uma periferia de rotor. No mínimo um segundo rotor tem uma pluralidade de sulcos helicoidais colocados ao redor de uma segunda periferia de rotor para acomodar os lobos do primeiro rotor durante rotação dos motores em direções opostas. Uma carcaça define uma câmara para encerrar os rotores. A máquina de deslocamento múltiplo inclui uma abertura de entrada de uma extremidade, uma abertura de saída em uma extremidade opostas, e uma abertura intermediária em uma parede lateral da câmara entre as aberturas de entrada e de saída. Uma câmara efetivamente fechada de trabalho em expansão é formada entre as aberturas de entrada e intermediária, enquanto uma câmara efetivamente fechada de trabalho em contração é formada entre as aberturas intermediária e de saída.
