Title: Innovations by Clifford C. Federspiel
Introduction
Clifford C. Federspiel is an accomplished inventor based in Shorewood, Wisconsin. He holds a total of 5 patents that showcase his expertise in airflow control systems and ventilation strategies. His work has significantly contributed to advancements in environmental control systems.
Latest Patents
One of his latest patents is the "Adaptive flow controller for use with a flow control system." This invention provides an adaptive airflow control system designed for positioning damper systems or controlling air units in environmental control systems. The system utilizes a fixed-gain, proportional-only feedback design to ensure stable operation despite the nonlinear behavior of flow through a valve or damper. It incorporates a time-dependent deadzone of nonlinearity to reject measurement noise, with an adaptively calculated proportionality constant that allows the control system to switch between various operating modes for optimal performance.
Another significant patent is the "Optimal ventilation control strategy." This invention offers a method for modeling multi-zone ventilation systems. It integrates flow rate standards with the concept of age of air, serving as the foundation for various ventilation effectiveness calculation methods. The method translates outdoor air requirements to age of air requirements and vice versa. It also facilitates the development of new ventilation strategies for multi-zone systems, minimizing the amount of outdoor air needed to maintain the age of the zone air at acceptable levels. This strategy ensures that the age of air in each zone conforms to ASHRAE Standard 62 requirements.
