Latest Patents

One of Jiejie Song's latest patents is a "Centrifugal compressor assembly and method of operation with an air conditioner." This invention features a motor that drives a first-stage compressor, incorporating a rotor stabilized by radial aerostatic bearings. These bearings utilize a low-viscous vapor-liquid two-phase fluid as a lubricating medium, which significantly reduces radial and axial oscillation of the rotor. This innovation allows for a reduction in seal clearance by half, thereby increasing the efficiency of the centrifugal compressor by at least 10 percent.

Another significant patent is the "Method for increasing load capacity on a porous aerostatic bearing with a two-phase fluid." This method enhances the load capacity of porous aerostatic bearings by using a less viscous two-phase fluid compared to traditional lubrication oils. The unique design allows for vaporization within the bearing gap, which increases pressure and load capacity, similar to hydrostatic bearings. This advancement also helps in managing heat generated by bearing friction, allowing for higher relative speeds between bearing surfaces.
