Latest Patents

One of his latest patents is the "Thrust bearing cooling unit for a turbo compressor." This system is designed to cool a turbo compressor by utilizing two compressing parts located on opposite ends of a rotational shaft driven by a motor. When the temperature of the bearing chamber increases, fluid from a fluid chamber within the casing is supplied to the bearing chamber. An open-and-shut valve is activated to supply fluid, ensuring optimal performance of the compressor.

Another significant patent is the "Cooling system and cooling method." This cooling system includes a compressor that compresses refrigerant through motor operation, along with a condenser, expansion means, and evaporator. It features a motor cooling device that efficiently cools the motor by directing some refrigerant from the condenser to the compressor based on the motor's temperature. This innovation effectively manages the heat generated during compressor operation.
