Fundamental study about an air conditioner which combined the magnetic refrigeration with humidity regulation system.

We have proposed a new humidity regulation system applying a magneto-caloric effect to the desiccant type humidity regulator. When magneto-caloric materials coated with the sorbent are heated by magnetizing, the moisture in the sorbent is released into the air. During demagnetization, the moisture in the air is adsorbed on the sorbent. One-dimensional numerical analysis codes which simulate the experiment were developed and verified the validity.The analysis which was considered the effect of high magnetic field was also done and it was clear that the performance might be raised remarkably by using high magnetic field. In addition, the performance calculation for the magnetic refrigerator using superconducting magnets was already carried out, and we have obtained the result that COP of 5-8 is predicted when ΔH is 10 T. The possibility to apply the large scale air conditioner using the magnetic refrigeration technologies with superconducting magnets and humidity regulation system was confirmed.
