Description
・インジェクションを実行しない場合の圧縮動力:Gr×(a+b)
・インジェクションを実行した場合の圧縮動力:Gr×a+(Gr+α)×c
(αはインジェクション量)
・両者の差:Gr×(a+b)−Gr×(a+c)=Gr×(b−c)
(ただし、インジェクション量αを除外して比較)
前記実施形態では、第2流量制御弁63として固定絞りを用いたが、第2流量制御弁63として膨張弁を用いることも可能である。この場合には、図4に示す変形例の冷凍サイクル装置100Aのように、気液分離器62内の圧力を検知する第2の圧力センサ(第2圧力検知手段)92を設け、この圧力センサ92で検知される中間圧Pmが所定圧力Pb以上となるように第2流量制御弁63の開度を制御手段8で調整してもよい。図4に示す例では、圧力センサ92は、バイパス路6の第1流量制御弁61と気液分離器62との間に設けられている。
