Patent number: 11913463Abstract: A compressor for a heat transfer circuit includes a variable frequency drive (VFD), an electric motor that rotates a driveshaft, bearing(s) for supporting the driveshaft, a backup gas supply, and a power supply. During a utility power interruption, the backup gas supply operates utilizing DC electrical power generated by a back electromotive force of the electric motor. A method of operating an electric power supply system for a compressor includes operating in a utility power mode and operating in a backup power mode during a utility power interruption. In the utility power mode, AC electrical power is supplied from the VFD to the motor. In the backup power mode, DC electrical power generated in the VFD by a back electromotive force of the motor it used to operate a backup gas supply to supply compressed working fluid to gas bearing(s) of the compressor.Type: GrantFiled: May 7, 2021Date of Patent: February 27, 2024Assignee: TRANE INTERNATIONAL INC.Inventors: Seth M.

Publication number: 20220387952Abstract: Combined combustion and pyrolysis (CCP) systems, and associated systems and methods, are disclosed herein. In some embodiments, the CCP system includes an input valve fluidly coupleable to a fuel supply to receive a hydrocarbon reactant, a CCP reactor fluidly coupled to the input valve, and a carbon separation component fluidly coupled to the CCP reactor. The CCP reactor can include a combustion chamber, a reaction chamber in thermal communication with the combustion chamber and/or fluidly coupled to the input valve, and an insulating material positioned to reduce heat loss from the combustion chamber and/or the reaction chamber. The CCP reactor can also include a combustion component positioned to combust a fuel within the combustion chamber. The combustion can heat the reaction chamber and the hydrocarbon reactant flowing therethrough. The heat causes a pyrolysis of the hydrocarbon reactant that generates hydrogen gas and carbon.Type: ApplicationFiled: June 3, 2022Publication date: December 8, 2022Inventors: Roelof E.
