Simulation of a magnetic cooling system and synthesis of its cooling capacity regulator

The article reviews existing designs of cooling systems and analyzes problems in their development and operation. As a result, a magnetocaloric refrigerator is selected as a research object. The refrigerator device under study and the processes occurring therein are investigated to develop a mathematical apparatus for simulating an active magnetic regenerator as the most problematic part of the refrigerator device. Subsequently, the system for controlling cooling capacity is synthesized and implemented in software form to regulate temperature fluctuations in steady-state mode at the boundary with heat dissipation. Simulation of transient heat transfer processes between a magnetic material and a coolant is carried out taking into account the spatial distribution of the object under consideration. The setting of the regulator is based on the static characteristic of changes in the coolant temperature on the value of magnetic induction in the orthocenter of the boundary plane with the cold heat exchanger.
