Oleg Podtchereniaev has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods of freezeout prevention for very low temperature mixed refrigerant systems
    Patent number: 7059144
    Abstract: Refrigerant freezeout is prevented by the use of a controlled bypass flow that causes a warming of the lowest temperature refrigerant in a refrigeration system that achieves very low temperatures by using a mixture of refrigerants comprising at least two refrigerants with boiling points that differ by at least 50° C. This control capability enables reliable operation of the very low temperature system.
    Type: Grant
    Filed: October 28, 2002
    Date of Patent: June 13, 2006
    Assignee: Helix Technology Corporation
    Inventors: Kevin Flynn, Mikhail Boiarski, Oleg Podtchereniaev
  • High efficiency very-low temperature mixed refrigerant system with rapid cool down
    Patent number: 6722145
    Abstract: The present invention is a refrigeration system that uses a nonflammable, nonchlorinated refrigerant mixture to achieve very-low temperatures using a single compressor. The system is characterized by both high efficiency and rapid cool down time.

  • Methods of freezeout prevention for very low temperature mixed refrigerant systems
    Publication number: 20030115893
    Abstract: Refrigerant freezeout is prevented by the use of a controlled bypass flow that causes a warning of the lowest temperature refrigerant in a refrigeration system that achieves very low temperatures by using a mixture of refrigerants comprising at least two refrigerants with boiling points that differ by at least 50° C. This control capability enables reliable operation of the very low temperature system.

  • Nonflammable mixed refrigerants (MR) for use with very low temperature throttle-cycle refrigeration systems
    Patent number: 6502410
    Abstract: Refrigerants containing HCFC's are replaced with new blends by using R-236fa and R-125, or R-125 with R-245fa, or R-236ea, or R-134a with R-236fa in place of HCFC's. No hardware or oil composition changes are required to maintain temperatures, pressures and capacity substantially unchanged in a refrigeration system.
