Latest Patents

One of his latest patents is a "Clean Negative Pressure Hospital Room System Using Compressor and Turbine." This invention effectively maintains a negative pressure state within hospital rooms by sucking air using a compressor. It creates a high-temperature and humid environment through water spray, the compressor, and a sterilization chamber, which helps eliminate bacteria and viruses. The compressor utilizes power generated by a turbine, and it is designed to recover heat from the air exiting the compressor to improve system efficiency. Additionally, some of the clean air produced in the sterilization chamber can be directly supplied back to the hospital room via a bypass mechanism.

Another notable patent is the "Cooling System Using Ejector and Membrane." This system dehumidifies and cools indoor air by employing an ejector, an ejector membrane, an evaporation chamber, and an indoor dehumidifying membrane. The cooling system's performance is enhanced by utilizing the evaporation latent heat generated in the evaporation chamber, which is driven by the suction force of the ejector. Furthermore, solar heat is harnessed to produce high-temperature and high-pressure steam, which is supplied to the ejector, thereby improving energy efficiency. The design incorporates two ejectors arranged in multiple stages to lower the temperature of the generated steam, further optimizing energy consumption.
