PROBLEM TO BE SOLVED: To provide a refrigeration cycle capable of maintaining an environment in a cabin relative to a trouble factor caused by an engine room without changing a through hole provided in a dash panel and a seal member for closing the through hole even if a specification has no inner heat exchanger.SOLUTION: A refrigeration cycle 1 includes: a refrigerant circuit 9 mounted to a vehicle and formed by interconnecting a compressor 2, a condenser 3, an expansion device 4 and an evaporator 5 through piping 61-66 to circulate a refrigerant; an inner heat exchanger 10 disposed in a cabin R; a connector 20 through which a flow passage 6 of the refrigerant between the condenser and a first heat exchange section and a flow passage 7 of the refrigerant between a second heat exchange section and the compressor pass; and a seal component 30 for closing a through hole 91 provided in a dash panel D. The seal component has a peripheral wall portion 31. The whole or part of the connector is accommodated in an accommodation space partitioned by the peripheral wall portion, and the whole or part of the expansion device has an outer shape that can be accommodated in the accommodation space.SELECTED DRAWING: Figure 1

    【課題】本開示は、内部熱交換器を備えない仕様となっても、ダッシュパネルに設けた貫通孔及び該貫通孔を塞ぐシール部材を変更することなく、エンジンルームに起因する不具合要因に対して、車室内の環境を維持できる冷凍サイクルを提供することを目的とする。【解決手段】本発明に係る冷凍サイクル1は、車両に搭載され、圧縮機2、凝縮器3、膨張装置4及び蒸発器5を配管61〜66で接続して冷媒を循環させる冷媒回路9と、車室Rに配置される内部熱交換器10と、凝縮器と第1の熱交換部との間の冷媒の流路6及び第2の熱交換部と圧縮機との間の冷媒の流路7が通るコネクタ20と、ダッシュパネルDに設けられた貫通孔91を塞ぐためのシール部品30と、を備え、シール部品は、周壁部31を有し、コネクタの全体又は一部は、周壁部によって区画された収容空間に収容され、膨張装置の全体又は一部は、収容空間に収容可能な外形形状を有する。【選択図】図1
