Abstract

"CICLO REFRIGERANTE". Um vaporizador (38) para ferver um refrigerante líquido a partir de uma mistura combinada de refrigerante líquido/lubrificante (32) desviada a partir de um evaporador (24) utiliza um refrigerante gasoso comprimido quente desviado (42) a partir de uma localização à montante do condensador. Em uma configuração preferencial, o refrigerante é desviado (60) partir de uma câmara de compressão (62) para dentro do compressor. O refrigerante quente (42) ferve de maneira eficiente o refrigerante líquido para fora da mistura (32) assegurando lubrificante de alta viscosidade. Em outras características, uma linha de lubrificante de retorno (56) a partir do compressor (22) passa para o interior de um poço (48) para adicionalmente ferver refrigerante líquido.
