Abstract

"COMPRESSOR". Um compressor helicoidal possui uma linha de injeção do economizador nas câmaras do compressor helicoidal. Uma válvula descarregadora comunica, seletivamente, a linha de injeção do economizador de volta para a sucção. Neste arranjo, os bter a injeção do economizador são também utilizados para obter a descarga de desvio da sucção e, assim, tanto projeto do compressor e do sistema, como a construção são simplificados.
