Abstract
CO2サイクル用のガスインジェクション方式を採用した多段圧縮機において、その圧縮効率および圧縮性能を向上させることができる多段圧縮機を提供することを目的とする。低段側ロータリ圧縮機構(4)で圧縮されたCO2冷媒ガスを密閉ハウジング(3)内に吐出し、密閉ハウジング(3)内の中間圧の冷媒ガスを高段側スクロール圧縮機構(5)が吸入して2段圧縮するCO2サイクル(1)用の多段圧縮機(2)において、密閉ハウジング(3)には、冷媒回路から抽出される中間圧のCO2冷媒ガスを、密閉ハウジング(3)内にインジェクションするガスインジェクション回路(15)が接続されるとともに、低段側ロータリ圧縮機構(4)と高段側スクロール圧縮機構(5)とは、略等圧力比で、かつ、押しのけ量比が略同等とされる。
