Review on magnetic refrigeration devices based on HTSC materials

The development of a high-efficiency magnetic refrigerating machine (magnetic refrigerator) with a superconducting magnetic field source operating in the room temperature range is currently an actual scientific and engineering problem. The analysis of scientific and technical literature, regulatory documentation, other materials as well as existing patent landscape for the specified topic is carried out in the paper. Main areas of further research are considered, and comparative assessment of their efficiency is carried out. Different concepts of the magnetic refrigerating machine with a superconducting magnetic system are discussed including general schemes of implementation of both the machine and its assemblies.
