A filter element (28) having planar (48) or cavity (30) geometry having applied thereto a coating (38, 39, 50, 53) of temperature super conducting (I-ITS) material characterised in that said filter element (28) or said coating of HTS material is provided with a porous structure (49A) or has associated therewith a plurality of cooling passages (29, 40, 42, 55) for passage of refrigerant when said filter element (28) is connected to a refrigeration circuit. The invention also includes a refrigeration circuit having a compressor (18) connected to a heat exchanger assembly (19) located in an evacuated housing (20) wherein the heat exchanger assembly (19) comprises 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).
A filter element having planar or cavity geometry having applied thereto a coating of temperature super conducting (HTS) material characterised in that said filter element or said coating of HTS material is provided with a porous structure or has associated therewith a plurality of cooling passages for passage of refrigerant when said filter element is connected to a refrigeration circuit.
A filter element as claimed in any preceding claim wherein the HTS material is formed from YSZ, YBCO, TBCCO 2223, TBCCO 2212 and BSCCO 223.
A filter element as claimed in any preceding claim wherein the cooling passages having a diameter of 20 microns to 5 mm or nanotube capillary passages are formed in a body of the filter element.
A refrigeration circuit incorporating a filter as claimed in any preceding claim.
A cavity type filter having a conducting layer of HTS material applied to a hollow interior of the cavity type filter.
