Title: Sean Francis and Evaporator Expansion Valve Stabilization.

Introduction

Sean Francis is an inventor based in Cologne, Minnesota, whose patent work addresses stability in climate control systems. His invention focuses on detecting unstable operation in an evaporator expansion valve and responding to it through a bypass pathway.

Latest Patents

Francis is associated with 1 patent, titled “Evaporator Expansion Valve Stabilization.” The patent describes a method for monitoring operating parameters of an evaporator expansion valve (EXV) and determining whether the valve is operating stably. If instability is detected, the system opens a bypass pathway containing an intermediate heat exchanger and a second expansion valve arranged in parallel with the first expansion valve. The heat exchanger cools part of the working fluid entering the EXV by using another portion of the working fluid. The patent also describes a climate control system with sensors and a controller that adjusts operation based on the EXV’s stability.

Career Highlights

Francis is associated with Thermo King Corporation. His patent reflects work on climate control technology, particularly methods for improving the operation of expansion valves and managing working-fluid flow.

Collaborations

The available information identifies Thermo King Corporation as Francis’s company affiliation. It does not specify additional collaborators or co-inventors for the patent.

Conclusion

Sean Francis’s patent presents a climate-control approach that detects evaporator expansion valve instability and uses a bypass pathway to support stable system operation.
