REFRIGERATION CYCLE DEVICE

To improve reliability at the time when a disproportionation reaction occurs in a refrigeration cycle device using a working medium containing HFO1123.SOLUTION: A refrigeration cycle has a compressor 16, an outdoor heat exchanger 15, expansion means, and an indoor heat exchanger, and uses a working medium containing 1,1,2-trifluoroethylene as a refrigerant. The refrigeration cycle is configured such that an outdoor unit 12 including the compressor 16, the outdoor heat exchanger 15 and the expansion means is provided with a communication part 129 that communicates a space housing the compressor 16 and the outside of the outdoor unit 12. Consequently, soot generated by disproportionation reaction is discharged from the communication part 129 to the outside of the outdoor unit. It is possible to reduce user's anxiety caused by the soot being blown out from a gap of the outdoor unit 12 vigorously, and it is possible to improve reliability.SELECTED DRAWING: Figure 5 【課題】ＨＦＯ１１２３を含む作動媒体を用いた冷凍サイクル装置の不均化反応発生時の信頼性の向上。【解決手段】圧縮機１６と、室外熱交換器１５と、膨張手段と、室内熱交換器とを有し、冷媒として１，１，２−トリフルオロエチレンを含む作動媒体を用いる冷凍サイクルにおいて、圧縮機１６と室外熱交換器１５と膨張手段とを備える室外機１２に圧縮機１６を収納する空間と室外機１２の外側とを連通する連通部１２９を設けた構成としてある。これにより、不均化反応で生じる煤が連通部１２９から室外機の外へと排出される。室外機１２の隙間から煤が勢いよく吹き出すことによる使用者の不安感を低減でき、信頼性を向上させることができる。【選択図】図５
