Title: Innovations by Fulin Gui
Introduction
Fulin Gui is an accomplished inventor based in Rockledge, FL (US), known for his contributions to refrigeration technology. He holds a total of 5 patents, showcasing his innovative approach to solving complex engineering challenges.
Latest Patents
Gui's latest patents include a Magnetic Bearing Centrifugal Refrigeration Compressor and Refrigerant. This invention utilizes a vapor compression refrigeration system, such as a water chiller, that employs a centrifugal compressor with magnetic bearings. The use of refrigerants like HFC-227ea and HFC-227ca minimizes enthalpy rise across the compressor and allows for single-stage compression for low cooling capacity. The magnetic bearings eliminate issues associated with lubricated bearings, enhancing the reliability of the compressor during operation.
Another significant patent is the Portable Refrigerant Recovery System. This electrically powered system employs a single manifold to streamline fabrication and reduce costs. It features a hot gas discharge port combined with a check valve, enabling the recovery system to function as both a vacuum pump and a refrigerant recovery device. The design includes a rectangular aluminum oil separator with internal baffles, strategically placed between the inlet and compressor. A low-voltage control circuit is implemented to prevent short cycling of the compressor, thereby extending its lifespan. This system also introduces an improved push-pull recovery method, allowing superheated refrigerant vapor to be efficiently diverted back to the unit being emptied, accelerating the recovery process.
