Latest Patents

One of Cheolho Bai's latest patents is an energy-saving refrigeration system that utilizes composition control with mixed refrigerants. This system circulates a mixture of R-134a, R-32, and R-125, with the composition being controlled by a vapor separator. The design incorporates a vortex generator to effectively separate the refrigerant mixture. For high thermal load operations, R-32 remains in the circulating line, enhancing cooling capacity, while R-134a and R-125 are stored in a tank. Conversely, during low thermal load operations, R-134a and R-125 circulate, improving energy efficiency, with R-32 stored separately. Additionally, multiple storage tanks can be employed to manage the composition of each refrigerant independently.

Another significant patent involves a refrigeration system with a de-superheating bypass. This system includes a compressor, condenser, expansion device, and evaporator, all connected in a closed circuit. A portion of the liquid refrigerant exiting the condenser is diverted through a secondary expansion valve and a heat exchanger. This setup allows the superheated refrigerant vapor to be cooled close to its saturation temperature before entering the condenser, thus eliminating the need for a de-superheating process. The result is a more efficient condenser that increases subcooling and cooling capacity while reducing compressor workload.
