To provide an ejector-type refrigeration cycle which can suppress the lowering of an air-conditioning capacity caused by a pressure loss of an ejector or a suction-side decompression part.SOLUTION: A bypass passage 21 for introducing a refrigerant flowing out of an outdoor heat exchanger 14 to a refrigerant inlet side of a suction-side evaporator 19, and an opening/closing valve 22 for opening and closing the bypass passage 21 are arranged at an ejector-type refrigeration cycle having an indoor condenser 12, the outdoor heat exchanger 14, a flow-out side evaporator 18 for evaporating the refrigerant flowing out of a diffuser part 16d of the ejector 16, and a suction-side evaporator 19 for evaporating the refrigerant which is decompressed by a fixed throttle 17, and making the refrigerant flow out to a refrigerant suction port 16c side of the ejector 16. Then, by using the indoor condenser 12 as a heat radiator, the bypass passage is opened at dehumidification and heating at which the outdoor heat exchanger 14, the flow-out side evaporator 18 and the suction-side evaporator 19 are used as an evaporator.SELECTED DRAWING: Figure 1

    【課題】エジェクタあるいは吸引側減圧部の圧力損失によって生じる空調能力の低下を抑制可能なエジェクタ式冷凍サイクルを提供する。【解決手段】室内凝縮器12、室外熱交換器14、エジェクタ16のディフューザ部16dから流出した冷媒を蒸発させる流出側蒸発器18、固定絞り17にて減圧された冷媒を蒸発させてエジェクタ16の冷媒吸引口16c側へ流出させる吸引側蒸発器19を備えるエジェクタ式冷凍サイクルに、室外熱交換器14から流出した冷媒を吸引側蒸発器19の冷媒入口側へ導くバイパス通路21、およびバイパス通路21を開閉する開閉弁22を設ける。そして、室内凝縮器12を放熱器として用い、室外熱交換器14、流出側蒸発器18および吸引側蒸発器19を蒸発器として用いる除湿暖房時にバイパス通路を開く。【選択図】図1
