| description | To provide a refrigerant compressor which can maintain the reliability of a slide part in the compressor.SOLUTION: A refrigerant compressor 1 of the present invention comprises a compressor mechanism part 720 for compressing a refrigerant, a rotating shaft 300 for driving the compressor mechanism part 720, and a slide bearing 10 (a main bearing 401, a slewing bearing 210) in at least one of an engagement part of the rotating shaft 300 and the compressor mechanism part 720 and a rotation pivot part of the rotating shaft. At least one out of R1234yf, R1234ze, R290 and R1270 is used as the refrigerant, or at least one out of these refrigerants and another refrigerant are combined for use. Refrigerator oil satisfies a condition that molecular weight is equal to or larger than 500, density is equal to or higher than 0.9 g/cm3, and the oil has a hydroxyl group at a terminal end of its chemical structure, or the refrigerant satisfying the condition and another refrigerator oil are mixed with each other, and a coating with a surface energy of 40 mN/m or more and 500 mN/m or less at a temperature of 20°C is formed on a slide face of the slide bearing 10.SELECTED DRAWING: Figure 3
【課題】圧縮機の摺動部の信頼性を維持できる冷媒圧縮機を提供する。【解決手段】本発明に係る冷媒圧縮機１は、冷媒を圧縮する圧縮機構部７２０と、前記圧縮機構部７２０を駆動する回転軸３００と、前記回転軸３００と前記圧縮機構部７２０との係合部および前記回転軸の回転支承部のうちの少なくとも一方にすべり軸受１０（主軸受４０１、旋回軸受２１０）を備え、前記冷媒は、Ｒ１２３４ｙｆ、Ｒ１２３４ｚｅ、Ｒ２９０およびＲ１２７０のうちの少なくとも一種を用い、またはこれらのうちの少なくとも一種と他の冷媒とを混合して用いられており、前記冷凍機油は、分子量が５００以上、密度が０．９ｇ／ｃｍ３以上および化学構造の末端に水酸基を有するという条件を満たし、または前記条件を満たすものと他の冷凍機油と混合されており、前記すべり軸受１０の摺動面に、表面エネルギーが２０℃において４０ｍＮ／ｍ以上５００ｍＮ／ｍ以下の被膜を備えている。【選択図】図３ |
