Title: Hakkyu Kim: Innovator in Heat Pump Technology
Introduction
Hakkyu Kim is a prominent inventor based in Daejeon-si, South Korea. He has made significant contributions to the field of heat pump systems, holding a total of 4 patents. His innovative designs focus on enhancing the efficiency and performance of vehicle heating systems.
Latest Patents
One of Hakkyu Kim's latest patents is a heat pump system for vehicles. This system features a complex valve device that includes a three-way valve, an on-off valve, expansion means, and connection blocks that are integrally formed. The three-way valve is connected to the refrigerant circulation line of the exterior heat exchanger, allowing the refrigerant to selectively bypass the exterior heat exchanger. The on-off valve controls the bypass line, while the expansion means selectively expands refrigerant discharged from the interior heat exchanger. This innovative design allows for efficient refrigerant control through the complex valve device.
Another notable patent is the heat pump system for vehicles and the method of controlling it. This invention determines when frosting begins on the exterior heat exchanger and initiates defrosting control if the temperature difference between the outdoor temperature and the refrigerant temperature exceeds a specific threshold. This proactive approach enhances frost prevention and defrosting effects, improving the heating performance and stability of the system.
