A rotary heat exchanger magnetic refrigerator.
Author(s) : KITANOVSKI A., EGOLF P. W., GENDRE F., et al.
Summary
A magnetic refrigerator with a cylindrical heat exchanger of porous periodic structure has been designed and numerical system performance calculations have been performed. This refrigerating machine, respectively heat pump device, can be operated with air or water as working fluid. In the article the design of the new refrigerator is outlined and the coupled basic equations of magnetism and thermodynamics are presented, which contain three independent characteristic geometrical quantities characterizing the heat exchanger structure. Magnetic fields, magnetic flux densities, and COP, etc. were investigated for magnetic inductions between 1 and 5 T. The obtained COPs are promising high compared to conventional refrigeration equipment working with gas compression and expansion.
