Liquefaction device for use in heat pump for liquefying medium to be condensed in industry, has condensation surface formed at condensation body, which comprises transit channel such that cooling medium is conducted through interior of body

摘要

The device (50) has a flow channel (21) for a medium to be condensed (23), and a condensation surface (38) formed at a rotatably mounted condensation body (30). The condensation body is rotational symmetrically formed and has a transit channel such that a cooling medium is conducted through interior of the condensation body. A hydrophobic coating is provided on a part of the condensation surface. The condensation body is extended from a lower end (51) of a centrifuge stage to an upper end (52) in an installation state, and partially consists of metal and/or a thermally conductive plastic. An independent claim is also included for a liquefaction method.
