Abstract
The refrigerating apparatus of the invention has a scroll compressor having a compressing section sucking and compressing a hydrofluorocarbon-based refrigerant, a condenser and the like, in which a plain bearing slidably supporting a driving shaft driving the compressing section of the scroll compressor is made of a material containing lead, and an ether oil miscible with the refrigerant used in a refrigerant circuit is used as a lubricant for lubricating the plain bearing.
Claims2
A refrigerant compressor comprising a compressing section sucking and compressing a refrigerant comprising at least one member selected from the group consisting of hydrofluorocarbon-based refrigerants, and a plain bearing slidably supporting a driving shaft for driving said compressing section;
- wherein said plain bearing comprises a member containing lead, and an ether oil miscible with said sucked and compressed refrigerant is used as a lubricating oil for said plain bearing, wherein said ether oil having misciblity with the refrigerant mainly comprises a cyclic ether-based compound.
A refrigerant compressor comprising a compressing section sucking and compressing a refrigerant comprising at least one member selected from the group consisting of hydrlfluorocarbon-based refrigerants, and a bearing slidably supporting a driving shaft for driving said compressing section;
- wherein said bearing comprises a rolling bearing, and an ether oil miscible with said refrigerant to be sucked and compressed is used as a lubricant for lubricating said rolling bearing, wherein said ether oil miscible with the refrigerant mainly comprises a cyclic ether-based compound.
