Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a refrigeration device that can prevent refrigerant from causing disproportionation reaction due to heat input from an electric motor of a compressor.SOLUTION: Refrigerant containing fluorohydrocarbon having property causing disproportionation reaction is used as refrigerant. A refrigeration device is provided with: a coil temperature detection part (70, 92) for detecting coil temperature of an electric motor (32); and a control part (93) for controlling the coil temperature detected by the coil temperature detection part (70, 92) to a prescribed temperature Ts or lower.SELECTED DRAWING: Figure 1 【課題】圧縮機の電動機からの入熱に起因して冷媒が不均化反応を起こすことを防止できる冷凍装置を提供する。【解決手段】冷媒として、不均化反応を起こす性質を有するフッ化炭化水素を含む冷媒が用いられる。冷凍装置には、電動機（32）のコイル温度を検知するコイル温度検知部（70,92）と、コイル温度検知部（70,92）で検知したコイル温度を所定温度Ts以下に制御する制御部（93）とが設けられる。【選択図】図１
