Zusammenfassung:	To suppress deterioration of cooling capacity even in a condition where an outside air temperature is high.SOLUTION: An ejector type refrigeration device includes: a circulation path 1 in which a heating heat exchanger 3, an ejector 4 and a condenser 5 are provided sequentially and a refrigerant is circulated among these elements sequentially; and a branch path 7 branched from a portion located between the condenser 5 and the heating heat exchanger 3 in the circulation path 1 and communicating with the ejector 4 via an expansion mechanism 40 and an evaporator 10. The branch path 7 includes an auxiliary booster 30 and a bypass path 31 bypassing the auxiliary booster 30.SELECTED DRAWING: Figure 1 【課題】外気温度が高い条件下においても冷却能力の低下を抑える。【解決手段】加熱熱交換器３、エジェクタ４及び凝縮器５が順次設けられ、これらの間に順次冷媒が循環される循環経路１と、循環経路１において凝縮器５及び加熱熱交換器３の間に位置する部分から分岐し、膨張機構４０及び蒸発器１０を介してエジェクタ４に連通する分岐経路７とを備えたエジェクタ式冷凍装置であって、分岐経路７に補助昇圧機３０及び補助昇圧機３０をバイパスするバイパス経路３１が設けられている。【選択図】図１
