Latest Patents

One of his latest patents is the "Dual heat source high-temperature regenerator." This invention aims to resolve issues associated with two conventional high-temperature regenerators. The first type, which uses a dedicated burner, incurs higher running costs, while the second type relies on exhaust gas from external systems, leading to limited capacity control. Sawakura's design features two inner shells within an outer shell, creating separate combustion and exhaust gas flues. The combustion gas flue is shaped like a sideways U, with a burner at the lower end and an exhaust duct at the upper end. The exhaust gas flue is straight and horizontal, with an inlet for exhaust gas. This innovative arrangement enhances the circulation of the dilute absorbent liquor, improving overall efficiency.

Another significant patent focuses on improving the response performance of absorption refrigeration machines. This invention reduces irregularities in solution concentration, which is crucial for adapting to changes in air-conditioning load. The design includes a spreader with openings of varying concentrations, strategically placed to optimize the flow of the solution. This configuration ensures a more consistent and efficient operation of the refrigeration system.
