Latest Patents

Kang’s listed patent portfolio includes 2 patents.

“Constant-Temperature Water Supply System Employing Carbon Dioxide Heat Pump, and Control Method Therefor” describes a system that uses a heat exchanger to transfer heat from a carbon dioxide heat pump to a water supply pipeline. By monitoring return-water and tank temperatures, the system directs water to a tank location with a similar temperature. This helps maintain stable temperature layering in the tank and supports constant-temperature water supply.

“Transcritical Carbon Dioxide Single-Stage and Double-Stage Compression Hot Water System and Control Method Therefor” describes a hot water system that can switch between single-stage and double-stage compression. Its components include compressors, heat exchangers, an expansion valve, a buffer water tank, and control valves. The system is designed to adapt to high- and low-temperature weather while maintaining heating capacity and energy efficiency.
