Zusammenfassung:PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of suppressing temperature slide to the extent of applicable to a heating use by avoiding the frost formation while increasing the mixture ratio of the refrigerant with a small GWP.SOLUTION: An air conditioner 1 comprises: a first decompression unit 51 for decreasing the pressure of the non-azeotropic refrigerant mixture flowing out of a condenser 4 until the gas-liquid two-phase state; a gas-liquid separator 11 for separating the non-azeotropic refrigerant mixture decompressed to the gas-liquid two-phase state into a gas-phase and liquid-phase; a first path 121 for supplying the gas-phase refrigerant in the gas-liquid separator 11 to an evaporator 6; a second path 122 for bypassing the liquid-phase refrigerant in the gas-liquid separator 11 with respect to the evaporator 6; an intercooler 13 for condensing the refrigerant flowing through the first path 121 by heat exchanging with the refrigerant flowing through the second path 122; a second decompression unit 52 for decreasing the pressure of the refrigerant flowing through the first path 121; and a third decompression unit 53 for decreasing the pressure of the refrigerant flowing through the second path 122.SELECTED DRAWING: Figure 1 【課題】GWPが小さい冷媒の混合比率を高めながらも、着霜の発生を回避して加熱用途に適用可能な程度にまで温度すべりを抑えることができる冷凍サイクル装置を提供すること。【解決手段】空気調和機1は、凝縮器4から流れ出た非共沸混合冷媒の圧力を気液二相の状態にまで減少させる第1減圧部51と、気液二相の状態にまで減圧された非共沸混合冷媒を気相および液相に分離する気液分離器11と、気液分離器11における気相の冷媒を、蒸発器6へと供給する第1経路121と、気液分離器11における液相の冷媒を蒸発器6に対してバイパスする第2経路122と、第1経路121を流れる冷媒を、第2経路122を流れる冷媒との間で熱交換することで凝縮させるインタークーラー13と、第1経路121を流れる冷媒の圧力を減少させる第2減圧部52と、第2経路122を流れる冷媒の圧力を減少させる第3減圧部53とを備える。【選択図】図1
