An oil-free centrifugal refrigerant compressor and lubricating method for low pressure refrigerant compressed into high pressure refrigerant, oil-free centrifugal refrigerant compressor includes a coolant flow passage, and compression module, radial bearing, first, into the collecting tank, and the first discharge, which has the compression module the compression device and a drive shaft, a radial bearing rotatably sheathed on the rotating shaft, and the first thing to import lubricating surface cooling fluid into the radial bearing, on the drive shaft drives the rotation and drives the compression to the low pressure refrigerant compressed into the high pressure the refrigerant, the refrigerant fluid lubrication with the radial bearing and the rotating shaft to provide proper lubrication effect, and the first discharge element is used to convert the lubricating cooling fluid discharge. Accordingly, the utility model can solve the pollution problem caused by grease lubrication of the existing compressor.
