Abstract

　エジェクタ式冷凍サイクル用ユニットは、エジェクタ（１３）と、エジェクタ（１３）の出口部（１３ｅ）の下流側に並列に接続され、エジェクタ（１３）の出口部（１３ｅ）から吐出された冷媒を蒸発させる第１蒸発器（１５）および第２蒸発器（１６）と、エジェクタ（１３）の出口部１３ｅから吐出された冷媒を第１蒸発器（１５）側と第２蒸発器（１６）側とに分配する冷媒分配器（１４、３３～３６）とを備える。エジェクタ（１３）は、冷媒を減圧膨張させるノズル部（１３ａ）から噴射される高速度の冷媒流によって冷媒吸引口（１３ｂ）から冷媒を吸引し、ノズル部（１３ａ）から噴射された冷媒と冷媒吸引口（１３ｂ）から吸引された冷媒とを混合して出口部（１３ｅ）から吐出する。また、エジェクタ（１３）の出口部（１３ｅ）から吐出された冷媒が冷媒分配器（１４、３３～３６）に直接流入するように、エジェクタ（１３）と冷媒分配器（１４、３３～３６）とが接続されている。
