Latest Patents

Jin is credited with 1 patent: “Magnetic levitation motor sealing-cooling apparatus for refrigeration system and method therefor.” The invention combines air cooling and water cooling to cool the motors of first-stage and second-stage compressors. It uses working medium from the first-stage compressor outlet to cool the second-stage compressor, while cooling gas from the second-stage motor cavity is used for the first-stage compressor. Cooling-water loops are also provided in both motor housings.

The patent further describes impeller-back-sealing and shaft-sealing structures for the compressors and an expander. A portion of the working medium leaving the second-stage compressor is directed into the expander to serve as sealing gas.
