Latest Patents
Friedhelm Franz holds a patent for a "Temperature and liquid level control system for fluid cycles." This control apparatus and method is designed to manage temperatures, temperature differences, and liquid levels in refrigeration cycles, such as those used in heat pumps and refrigeration installations. The system operates independently of the refrigerating medium and application field. It utilizes two-position relay control valves that are electromagnetically actuated and fluid pressure-operated. These valves are suitable for large numbers of cycles and are wear-resistant. The design effectively avoids instabilities in the refrigeration medium cycle, ensuring that variations in the evaporation endpoint do not negatively impact the control system's functionality. The conventional thermostatic expansion valves are replaced with high-frequency switching, wear-resistant two-position valves.
