PROBLEM TO BE SOLVED: To suppress the generation of disproportionation reaction in refrigerant.SOLUTION: In a rotary compressor, the refrigerant is HFO1123 refrigerant or mixed refrigerant including the HFO1123 refrigerant, and 0<N×(Q/A)≤15000 and 0.0016×Q≥D×h are satisfied where Q[mm] is the displacement volume of a cylinder chamber, A[mm] is the opening area of a discharge hole, N=60[rps] is the rotation speed of a motor, D[mm] is the diameter of the discharge hole, and h[mm] is the maximum movement amount of the front end of a discharge valve when moved on the center line of the discharge hole relative to the discharge hole.SELECTED DRAWING: Figure 4 【課題】冷媒に不均化反応が生じることを抑制する。【解決手段】ロータリ圧縮機において、冷媒は、ＨＦＯ１１２３冷媒、またはＨＦＯ１１２３冷媒を含む混合冷媒であり、シリンダ室の排除容積をＱ［ｍｍ３］、吐出孔の開口面積をＡ［ｍｍ２］、モータの回転数をＮ＝６０［ｒｐｓ］、吐出孔の直径をＤ［ｍｍ］、吐出孔の中心線上において吐出弁の先端部が吐出孔に対して移動する最大移動量をｈ［ｍｍ］としたとき、０＜Ｎ×（Ｑ／Ａ）≦１５０００、０．００１６×Ｑ≧Ｄ×ｈを満たす。【選択図】図４
