A filter element ( 28 ) having planar ( 48 ) or cavity ( 30 ) geometry having applied thereto a coating ( 38, 39, 50, 53 ) of temperature super conducting (HTS) material in which the filter element ( 28 ) or coating of HTS material is provided with a porous structure ( 49 A) or has associated therewith a plurality of cooling passages ( 29, 40, 42, 55 ) for passage of refrigerant when the filter element ( 28 ) is connected to a refrigeration circuit. A refrigeration circuit includes a compressor ( 18 ) connected to a heat exchanger assembly ( 19 ) located in an evacuated housing ( 20 ), wherein the heat exchanger assembly ( 19 ) includes an influent line ( 22 ), a first heat exchanger unit ( 21 ) in communication with the influent line ( 22 ), a throttle valve ( 23 ) which is in communication with the filter ( 28 ), a second heat exchanger unit ( 25 ) in communication with the filter ( 28 ) and a return line ( 26 ) to the compressor ( 18 ). |
