Patents by Inventor Steffen Korfmann

Steffen Korfmann 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).

  • Patent number: 9506701
    Abstract: A cold and/or heat accumulator has a first heat exchanger and preferably a second heat exchanger. The first heat exchanger may, in particular, be provided to be perfused by a refrigerant while the second heat exchanger is preferably perfused by brine. The first heat exchanger and preferably also the second heat exchanger are engaged in a heat-exchanging relationship with carrier elements charged with a cold or heat storage medium and may, in particular, be formed by graphite strips.
    Type: Grant
    Filed: May 29, 2006
    Date of Patent: November 29, 2016
    Assignee: WEBASTO AG
    Inventors: Noureddine Khelifa, Wolfgang Krämer, Steffen Korfmann, Thomas Peters

    Abstract: The invention relates to a cold and/or heat accumulator comprising a first heat exchanger and preferably a second heat exchanger. The first heat exchanger may, in particular, be provided to be perfused by a refrigerant while the second heat exchanger is preferably perfused by brine. The first heat exchanger and preferably also the second heat exchanger are engaged in a heat-exchanging relationship with carrier elements charged with a cold or heat storage medium and may, in particular, be formed by graphite strips. The cooling energy and/or heat accumulator according to the invention exhibits a good heat conduction, short charging times, a high cooling or heating performance, low pressure losses as well as a good cooling agent distribution. Further its integration options are manifold due to the selected fixation means.

  • Patent number: 7290599
    Abstract: A system for heating and cooling the interior of a motor vehicle includes a first climate control device designed to heat or cool a front area of the interior, and a second climate control device designed to heat or cool a rear area of the interior. A first evaporator connectable to a first cooling agent circuit assigned to the first climate control device and a second evaporator is connectable to a second cooling agent circuit assigned to the second climate control device. The second evaporator is located in a latent storage in order to charge the latent storage with cold and the second climate control device contains a first heat exchanger designed to transfer the cold removed via a heat transfer medium circuit or the second cooling agent circuit from the latent storage for cooling the rear area of the interior by an air flow.
