Title: Harold L. Jeffery: Innovator in Temperature Control Systems
Introduction
Harold L. Jeffery is a notable inventor based in Ft. Wayne, IN (US). He has made significant contributions to the field of temperature control systems, holding a total of 4 patents. His work primarily focuses on improving the efficiency and effectiveness of heating and cooling systems.
Latest Patents
One of Jeffery's latest patents is related to the "Leaving Air Temperature Control of Cooling System." This invention monitors the temperature of air leaving a cooling coil, ensuring it does not drop below various threshold values. The system reduces the number of cooling stages chilling the refrigerant when the temperature falls below a first threshold. It continues to adjust damper positions to regulate airflow to the cooled zones based on previously sensed temperatures. If the temperature drops below a third threshold, all cooling stages are turned off.
Another significant patent is the "Leaving Air Temperature Control of Heating System." This invention monitors the air temperature leaving a heating coil, ensuring it does not rise above a first threshold temperature. An offset value is calculated for damper positioning when the temperature exceeds this threshold. The system maintains this offset until the temperature drops below a second threshold. Additionally, any supplementary heating sources are turned off if the temperature rises above a third threshold.
