Résumé

Trifluoroethene (HFO-1123) has a very low global warming potential (GWP) and ozone depletion potential (ODP); thus, it has been proposed as a next-generation refrigerant. However, a short circuit in a motor under high temperature and pressure conditions may cause a disproportionation reaction of HFO-1123. Therefore, to commercialize a split air conditioner using HFO-1123, it is necessary to develop a technology to suppress this disproportionation reaction. In this study, disproportionation experiments were conducted under various temperature and pressure conditions. Variations in pressure, temperature, and input energy were recorded. Using a discharge method, we experimentally determined the threshold pressure of the disproportionation reaction. The disproportionation reaction was photographed using two high-speed cameras, and the flame temperature was measured using the two-color temperature radiometry method. The experiment was conducted using R32 and trifluoroiodomethane (R13I1) as the disproportionation reaction inhibitors, and the suppression effect of the disproportionation reaction was evaluated.
