Control method for air flow in electric heater mixing plenum
A recently granted patent (Publication Number: US11906245B2) discloses a method for controlling air flow through an electric heater mixing plenum in various systems, including air recirculation and drying systems. The method involves adjusting the positions of inlet and outlet dampers in different chambers of the plenum to regulate air flow based on monitored properties such as temperature, pressure, and humidity. By monitoring and adjusting the dampers, the system can optimize energy efficiency and performance based on factors like electric energy costs and fossil fuel costs. Additionally, the method includes provisions for shutting down and restarting the electric air heater, as well as increasing fossil fuel input into a combustion system when necessary.
Furthermore, the patent details the specific configurations and operations of the electric heater mixing plenum in different scenarios, such as in air recirculation systems and drying systems. The method involves precise control of inlet and outlet dampers in multiple chambers, including those with resistance-type electric air heaters, to ensure efficient air flow and temperature control throughout the system. By monitoring and comparing temperatures at various points within the plenum, the method can adjust the damper positions to maintain optimal conditions. Additionally, the inclusion of humidity measurements and adjustments based on measured humidity levels further enhances the system's ability to regulate air flow and volume effectively. Overall, the patented method offers a comprehensive approach to controlling air flow in electric heater mixing plenums, catering to different applications and optimizing energy usage based on specific operational requirements.
