<p>A superconductor refrigeration system incorporates thermal superconducting elements accommodating heat transfer. The system includes an intensifying heat exchanging subsystem having a compressor (24) and two heat exchangers, (21,28) serially connected into a reversible refrigerating loop, a refrigerating heat exchange coil (55) formed from a thermal superconductor material and being in thermal communication with one heat exchanger, and a dissipating heat exchange coil (55a, 88) formed from a thermal superconductor material and thermally connected with the second heat exchanger. The refrigerating heat exchange coil (55) and the dissipating heat exchange coil (55a, 88) are connected to the respective heat exchangers (21, 28) by an evaporator heat exchange segment (34) and a condenser heat exchange segment (32) respectively. The system also includes a switch (36, 64, 64a, 64b, 64c ) which allows to alternatively connect the heat exchange coils with either one of the heat exchangers (21, 28 ) in order to change the mode of operation of the system from a refrigerating to defrosting.</p> |
