To provide a refrigeration cycle device enabling reduction of manufacturing costs by simplifying the configuration.SOLUTION: A refrigeration cycle device 1 capable of simultaneously performing cabin interior air-conditioning and battery cooling includes a compressor 2, a condenser 3, a first decompression mechanism 4, a second decompression mechanism 5, a battery evaporator 6, an air-conditioning evaporator 7 and an evaporation pressure regulating valve 8. A refrigerant compressed by the compressor 2 is condensed by the condenser 3 and decompressed by the first decompression mechanism 4 and the second decompression mechanism 5. The battery evaporator 6 cools a battery by using evaporation heat of the refrigerant that has flowed out of the first decompression mechanism 4. The air-conditioning evaporator 7 generates air-conditioned air for cabin inner air-conditioning by using evaporation heat of the refrigerant that has flowed out of the second decompression mechanism 5. The evaporation pressure regulating valve 8 is provided in the middle of piping that connects the battery evaporator 6 with the compressor 2 to maintain the evaporation pressure of the refrigerant flowing in the battery evaporator 6 at a higher level than that of the refrigerant flowing in the air-conditioning evaporator 7.SELECTED DRAWING: Figure 1

    【課題】構成を簡素にすることにより製造上のコストを低減することの可能な冷凍サイクル装置を提供する。【解決手段】車室内空調と電池冷却とを同時に行うことの可能な冷凍サイクル装置1は、圧縮機2、凝縮器3、第1減圧機構4、第2減圧機構5、電池用蒸発器6、空調用蒸発器7および蒸発圧力調整弁8を備える。圧縮機2で圧縮された冷媒は、凝縮器3で凝縮され、第1減圧機構4と第2減圧機構5によって減圧される。電池用蒸発器6は、第1減圧機構4から流出した冷媒の蒸発熱により電池を冷却する。空調用蒸発器7は、第2減圧機構5から流出した冷媒の蒸発熱により車室内空調のための空調風を生成する。蒸発圧力調整弁8は、電池用蒸発器6と圧縮機2とを接続する配管の途中に設けられ、電池用蒸発器6を流れる冷媒の蒸発圧力を、空調用蒸発器7を流れる冷媒の蒸発圧力より高く維持する。【選択図】図1
